Answer:
This is an example of natural selection. There were two types of moth colors, white and black and white. Before the industrial revolution, the environment had white trees, meaning that the white moths can blend in. The black moths are more likely to be eaten because they stick out. Now that the trees are black, the white moths stick out more causing there to be more black moths.

Explain how the sugars, phosphates, and nitrogenous bases in one strand of DNA connect to a complementary strand during replication
Answer: One strand of DNA binds to another via base complementarity.
Explanation:
The two strands of the DNA double helix are connected through nucleotides. There are hydrogen bonds between the nitrogenous bases. Each nucleotide has a sugar, nitrogenous base and phosphate group. The phosphate group and sugar forms the backbone of the DNA double helix. The nitrogenous base form pairing with each other via base complementarity. Purines are adenine and guanine and pyrimidine are cytosine and thymine these are nitrogenous bases. The adenine bonded with thymine via two hydrogen bonds and cytosine with guanine with three hydrogen bonds. These nitrogenous bases help in replication process.
The two strands of DNA are actually connected by hydrogen bonds (H-bonds) between the nitrogenous bases.
There are 2 hydrogen bonds between adenine and thymine, and 3 hydrogen bonds between cytosine and guanine.
Why are sugar-phosphate and nitrogenous bases important to DNA molecules?The sugar-phosphate backbone is a significant component of DNA's double helix structure.
The structure of DNA is tied to its function. The pairing of the nitrogenous bases that are connected to the sugar-phosphate backbone play a key role in the ability of DNA to store and transfer genetic information.
Thus, base complementary is the reason.

What are Eukaryotic organisms?Eukaryotic organisms may be defined as those organisms whose cells have a well-defined nucleus and the existence of membrane-bound cell organelles. They are single-celled or multicellular in nature. They belong to the group of organisms Eukaryota or Eukarya.
There is a large range of eukaryotic organisms in nature. Examples of eukaryotic organisms are all animals, plants, fungi, protists, and most algae. While bacteria are classified into the category of prokaryotic organisms.
Viruses are neither eukaryotic nor prokaryotic in nature. This is because they are non-cellular and can not able to multiply or reproduce outside the living host.
Therefore, eukaryotic organisms are fungi, plants, and animals. Thus, the correct options are B, C, and E.

Answer:
My answer is the genotypes are BB, Bb, Bb, and bb.
Explanation:
I attached a photo of the punnet square after crossing the genotypes Bb and Bb. Crossing the B on top with the B on the side results in the genotype BB. Crossing the b on top with the B on the side results in Bb. The genotype that results is written in the box that connects the row and the column (such as top row and left column results in BB).

Which statements correctly describe herbivores and carnivores?
Choose all that apply:
Carnivores are often secondary or higher consumers.
Carnivores are often primary consumers.
Herbivores are often primary consumers.
Herbivores are often producers.
Answer:
The First and Third one for sure
Explanation:
Carnivores eat primary consumers as well as other carnivores if I'm not wrong, which would make them secondary or higher consumers.
Also, herbivores eat producers, which are plants and stuff and basically organisms that make their own food, which would make them primary consumers.
Which of the following statements is NOT correct?
O Heat energy is needed to melt ice into water.
O The most important source of water in the atmosphere is conduction from the oceans.
O Water reaches the land surface as rain or snow and is transported to the ocean by streams, rivers, and lakes.
O Liquid water from the Earth's surface is evaporated into a gaseous form and enters the atmosphere as water vapor.
Answer:
it's O n2. So, The most important source of water in the atmosphere is conduction...
Explanation:
Hope that helps! (Btw I did this test and got it correct)
The statement "The most important source of water in the atmosphere is conduction from the oceans" is not correct.
The most important source of water in the atmosphere is evaporation.
What is evaporation?Evaporation is a process through which a liquid transforms into a gas. It's a type of vaporization that occurs specifically at the surface of a liquid. Whenever a liquid gets heated the molecules, near its surface gain energy. Become more active. These energetic molecules tend to collide with each other resulting in some of them escaping from the liquids surface and entering the gas phase.
In terms of sourcing water for the atmosphere, evaporation of water from the Earths surface plays a role. Although water vapor does come from the oceans through conduction it's not the source that we rely on.

The pedigree below shows the inheritance of a dominant allele of a gene in a family over several generation. Circles represent females and squares represent males. Shaded symbols indicate individuals carrying the allele. The pedigree suggest that the gene is on a nuclear chromosome, and not on a mitochondrial DNA, because A) mitochondrial genes are not heritable B) mitochondrial mutations cannot produce dominant traits C) maternal mitochondrial mutations are inherited by all of a mother's offspring D) mitochondrial DNA is circular, whereas chromosomal DNA is linear
Complete question:
You will find the pedigree in the attached files
Answer:
The correct option is C) maternal mitochondrial mutations are inherited by all of a mother's offspring.
Explanation:
Mitochondrial inheritance is one of the ways in which a disease or a trait might be inherited from the maternal line.
Most of the DNI is located in the nucleus, but there is also DNI in mitochondria. Sperm cells hardly carry mitochondria, so mitochondrial DNI is mostly inherited from the maternal side. If there exists any mutation in this DNI, the whole progeny of the mutated woman will be affected, as they will get the mother´s mitochondria carrying the mutation. On the contrary, if there is a man affected by a disease caused by a mutation in mitochondrial DNI, non of their descendants will get the disease.
In the exposed pedigree, we can see that the mother is affected by the disease, but the couple had two daughters, and only one of them was affected, while the other one was not. This tells us that the mutation occurred on a nuclear chromosome. If the mutated allele was in mitochondria, both daughters would be affected.
The pedigree suggests that the gene is on a nuclear chromosome, and not on a mitochondrial DNA because maternal mitochondrial mutations are inherited by all of a mother's offspring (Option C).
Mitochondrial DNA (mtDNA) is a special type of genetic material that exhibits a matrilineal inheritance pattern.In consequence, all genes (and mutations) contained in mtDNA will pass from the mother to her offspring.It is for that reason that mtDNA is widely used in evolutionary studies (we can trace matrilineal lineage from mtDNA).In conclusion, the pedigree suggests that the gene is on a nuclear chromosome, and not on a mitochondrial DNA because maternal mitochondrial mutations are inherited by all of a mother's offspring (Option C).

Which of these processes does not occur as part of the cell cycle in animal cells?
1) Mitochondrial DNA is released into the cytoplasm
2) Two identical copies of chromosomes are produced
3) Cell growth and mRNA synthesis occur
4) Nuclear DNA is replicated
The cell cycle is an essential process of growth and function. It has many phases which divide the genetic material and the cytoplasmic organelle equally into new cells. The cell cycle is crucial for survival.
Option 1) Mitochondrial DNA released into the cytoplasm is the process that does not occur in the animal cell cycle.
Cell cycle steps in animals can be explained as:In the animal cell cycle during the synthesis step, the genetic material replicates to produce two identical chromosomal groups.The cell divides to grow and the processes of central dogma including mRNA synthesis and protein formation occur.Mitochondrial DNA does not get released in the cytoplasm but remains sustained in the mitochondria structure.Therefore, mitochondrial DNA is not discharged into the cytoplasm.
