Substitution:
Substitution is the switch of codons. A C could be switched to an A, but the original is now substituted for the new codon. This can change the amino acid present or it can be a silent mutation. If the stop codon is switched in, the protein will be cut short and the effects could be very serious.
Insertion:
Insertion is where base pairs are inserted into the DNA. This is different from substitution because nothing is getting switched out, just new ones are getting inserted. The original codons will still be present, just new ones are coming in. Insertions result in a frame-shift, which means everything after the mutation is shifted and nothing will be correct after this. Insertions are more harmful than substitution because it doesn't affect just one amino acid, but many.
Deletion:
Deletion is where some codons or DNA is deleted. This will result in everything after the mutation being incorrect and can cause drastic effects. Deletion is very similar to insertion because they both cause a frame-shift, but also very different because they do the opposite from one another. Deletion is also more harmful than substitution because of the frame-shift and the change in future amino acids.

Consider this plant cell.
The organelles in a plant cell are labeled. Part E is a complex of vesicles and folded membranes within the cytoplasm.
Which organelle is labeled E?
Golgi apparatus
chloroplast
ribosome
nucleus
Mark this and return
The correct answer is A. Golgi apparatus
Explanation:
In a plant cell, the cytoplasm contains organelles such as the chloroplast, the ribosome, the Golgi apparatus, among others. From these organelles, the Golgi apparatus is the one that is composed of vesicles and folded membranes, which makes it look like a system of flattened, long, and folded sacs or membranes connected. Additionally, this organelle is in charge of process proteins and lipids by packaging and modifying these before they go to other sections or organelles in the cell. According to this, the organelles labeled E is likely the Golgi apparatus because only this includes a set of vesicles and folded membranes.

Which eras ended with a mass extinction?
O A. Paleozoic and Precambrian
O B. Mesozoic and Paleozoic
OC. Mesozoic and Cenozoic
O D. Cenozoic and Paleozoic
B. Mesozoic and Paleozoic eras ended with mass extinctions.
What is Mass extinctions?Mass extinctions are periods in Earth's history when a significant proportion of the planet's biodiversity is wiped out in a relatively short period of time.
These events have occurred several times throughout Earth's history, and they are typically associated with major geological and environmental changes.
The Mesozoic era, which lasted from about 252 to 66 million years ago, ended with the Cretaceous-Paleogene extinction event. This event was likely caused by the impact of a large asteroid or comet, which triggered a range of environmental changes, including wildfires, acid rain, and a nuclear winter-like effect.
The event is most famous for wiping out the dinosaurs, but it also resulted in the extinction of many other species, both on land and in the oceans.
The Mesozoic era ended with the Cretaceous-Paleogene extinction event, which wiped out the dinosaurs and many other species.
The Paleozoic era ended with the Permian-Triassic extinction event, which was the largest mass extinction in Earth's history, and resulted in the loss of approximately 96% of all marine species and 70% of land species.

The instructions for making proteins are coded in the (cytoplasm / DNA / endoplasmic reticulum / nucleus) of a cell. In a eukaryotic cell, these instructions are located in the (cytoplasm / DNA / endoplasmic reticulum / nucleus).
Answer:
The instructions for making proteins are coded in the (cytoplasm / DNA / endoplasmic reticulum / nucleus) of a cell. In a eukaryotic cell, these instructions are located in the (cytoplasm / DNA / endoplasmic reticulum / nucleus).
Explanation:
The genetic code is contained in DNA, or deoxyribonucleic acid. This is usually the same among most organisms, save some RNA viruses. But in eukaryotes, the DNA is in the nucleus, whereas in prokaryotes the DNA is in the "nucleoid region", or a twisted up section near the middle of the cell.
The instructions for making proteins are coded in the DNA of a cell. In a eukaryotic cell, these instructions are located in the nucleus.
What is DNA?Deoxyribonucleic acid is a polymer made up of two polynucleotide chains that coil around each other to form a double helix that contains genetic instructions for the development, functioning, growth.
it is also involved in reproduction of all known organisms and viruses. Nucleic acids include DNA and ribonucleic acid.
The information molecule is DNA. It stores instructions for the production of larger molecules known as proteins.
These instructions are stored in the nucleus of each of your cells and are distributed across 46 long structures known as chromosomes.
These chromosomes are composed of thousands of shorter DNA segments known as genes.
DNA is a linear molecule made up of four different types of smaller chemical molecules known as nitrogenous bases.

Explanation:
A botanist has acquired a group of pea plants. All of the pea plants have yellow pea pods (the recessive form of this trait) except for one, which has green pea pods (the dominant form of this trait). The botanist decides to use a test cross to determine the genotype of the green pea pod plant for this trait. The botanist performed the test cross and found the following: 50% of the offspring had yellow pea pods and 50% of the offspring had green pea pods. Based on this information, what was the genotype of the initial green pea pod plant
Answer:
Hetezygous
Explanation:
The genotype of the initial green pod plant would be heterozygous.
Let pea pod color be represented by C (c) alleles.
First, let us assume that the genotype of the green pea pod plant is homozygous dominant, CC. This was crossed with homozygous recessive, cc.
CC x cc
Cc Cc Cc Cc
All the progeny will have Cc genotype with phenotypically green color. This is in contrast to the result obtained from the test cross in the illustration, hence the genotype of the initial green pea pod plant cannot be homozygous dominant.
Now, let us assume that the genotype is Heterozygous, Cc.
Cc x cc
Cc Cc cc cc
50% of the progeny has Cc genotype with phenotypically green color while the remaining 50% has cc genotype with phenotypically yellow color. This is consistent with the result from the illustration.
Hence, the genotype of the initial green pea pod plant is heterozygous.
Albino is a rare recessive genetic disease. Sally and her parents are normal but her sister is albino. It seems that Sally has chance to carry the albino allele. If she marries a normal person with no family history of albinos, what is the chance for Sally's first baby to be a carrier of the recessive allele?
Answer:
2/3 ×2/3× 1/4
Explanation:
Albino is a rare recessive genetic disorder which is characterized by low production of melanin or no melanin production. It is an inheritable disorder can be pass from generation to generation. Since the parent of Sally has no Albino and Sally sisters has, it means there is an history of Albino in the family that make her sister to have. She has 2/ 3 chance of having and the possibility that her first child will have is 1/4 meaning 25% because her hubby has no Albino history in their family.

In lab we looked at succession using marine organisms. The process of succession also happens because of wildfires, and those communities do recover and follow the general model of succession. Below is a photo I took one year after a fire at Lake Tahoe. You can see see the burned trees in this photo. What proportion of r-selected species relative to K-selected species should we expect to see at this early stage of recovery? a. # of r-selected species > # of K-selected species b. # of r-selected species = # of K-selected species c. # of r-selected species < # of K-selected species. The diagram is given in the attachment below.
Answer:
The correct answer is option A, that is, the population of r-selected species will be more in comparison to the k-selected species.
Explanation:
Based on the evolutionary strategies, the preferred selection of the species that generate small body sizes, short life span offspring, and exhibit early semelparity and thrive in unstable surroundings is r-selection. These species possess the tendency to overcome the huge loss of offspring and are considered opportunists.
On the other hand, the preferred selection of the species that exhibit delayed reproduction, generate few large body size, possess long life span offspring and iteroparity, and thrive in stable surroundings is k-selection. Thus, it is clear that the r-selected species will be more in number than the species that are k-selected as r-selection plays an essential role in the initial phases of succession.
Mutations and DNA replication errors can alter base sequences, thereby potentially creating or eliminating recognition sites. Group of answer choices True False
Answer:
The given statement is true.
Explanation:
An error at the time of the replication of DNA or mutation can either result in the addition or deletion of DNA bases that eventually makes a substantial change in the sequence of DNA, and thus, will exhibit a substantial influence on the recognition sequence because of which one can witness a change in the site of recognition.
This variation witnessed in the DNA's recognition site can be evaluated by treating the mutated DNA with the restriction enzymes that exhibit a uniqueness for the restriction sites. Afterward, by going through the process of gel electrophoresis one can witness the change in the number of bands of DNA showing variation in the restriction sites.

Why do sex-linked traits follow different patterns of inheratance than other traits
Answer:
Males and females have different sex chromosomes.
Explanation:
Sex Linked trait is controlled by the chromosomes while other traits are controlled by autosomes. The autosomal cells and traits have a constant characteristics in a human being. The chromosomal cells however vary. The male chromosome XY is different from the female chromosome XX.
This is the reason why sex-linked traits follow different patterns of inheratance than other traits as a result of the Males and females having different sex chromosomes is valid.
This skull belongs to a multituberculate non-therian mammal, Taeniolabis, from the Paleocene. It looks superficially like some rodent skulls. Given that multituberculates diverged before rodents had evolved, would their overall similarity be homologous or convergent
Answer:
Convergent evolution
Explanation:
Convergent evolution can be described or explained as a process in evolution in biology. It usually occurs when two species from unrelated lines develop the same traits or features. This is believed to have happened due to the fact that they live in similar or related habitats, and have to develop solutions to the same kind of problems.
Therefore, in this case, the type of evolution between the two organisms mentioned is convergent.

The examples of organisms that are used in making alcohol and yoghurt are Sacharomyces cerevisae, which is yeast, and Lactobacilli spp respectively.
Why does secondary session occur faster them primary secession
Answer:
During secondary succession, the soil isn't damaged hence there is no need for pioneering species such as lichens to dissolve the damaged soil into organic ones that can sustain more complex plants.
Explanation:
Secondary succession, type of ecological succession (the evolution of a biological community’s ecological structure) in which plants and animals recolonize a habitatafter a major disturbance—such as a devastating flood, wildfire, landslide, lavaflow, or human activity (e.g., farming or road or building construction)—significantly alters an area but has not rendered it completely lifeless. Secondary succession is distinguished from primary succession, in which a biological community develops where no life had existed
Secondary succession, type of ecological succession (the evolution of a biological community’s ecological structure) in which plants and animals recolonize a habitatafter a major disturbance—such as a devastating flood, wildfire, landslide, lavaflow, or human activity (e.g., farming or road or building construction)—significantly alters an area but has not rendered it completely lifeless. Secondary succession is distinguished from primary succession, in which a biological community develops where no life had existed previously.
Secondary succession follows a major disturbance, such as a fire or a flood. The stages of secondary succession are similar to those of primary succession; however, primary succession always begins on a barren surface, whereas secondary succession begins in environments that already possess soil. In addition, through a process called old-field succession, farmland that has been abandoned may undergo secondary succession.
Secondary succession takes place where a disturbance did not eliminate all life and nutrients from the environment. Although fire, flooding, and other disturbances may bring visible ruin to a landscape, drive out many plants and animals, and set back the biological community to an earlier stage, the habitat is not lifeless, because the soil retains nutrients and seeds that were set down before the disturbance occurred. Buried seeds can sprout shortly after the effects of the disturbance pass, and some may have greater success from reduced competition and reduced shading. Some species may be adapted to the frequent passage of a particular disturbance. For example, the jack pine (Pinus banksiana), a tree species common in the northeastern U.S. and Canada, requires heat from a wildfire to open its cones (strobili) before seeds can be spread for new growth.
