what is the answer of this question?

Answer: peptide bonds

Explanation:

A peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water.

This is a dehydration synthesis reaction (also known as a condensation reaction), and usually occurs between amino acids.

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.

The given question is not complete, the complete question is:

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.

4. The formation and evolutuion of stars and galaxies

The interphase (G1, S, and G2 phases) precedes meiosis (Meiosis 1 and meiosis 2). Immediately after meiosis, cytokinesis occurs.

1: S phase / 2: Anaphase 1 and 2 / 3: cytokinesis / 4: S phase / 5: Prophase 1.

---------------------------------

The interphase occurs before cell division. It is composed of the G1, S, and G2 stages.

During the S stage occurs the DNI replication process. At this point, also happens the synthesis of histones and other associated proteins. This is the only stage where the DNI molecule is replicated.

Among the enzymes involved in the DNA replication process, two of them are  

•  Responsible for DNA elongation by adding nucleotides to the growing chain, from 3' to 5' extremes.

•  It includes only nucleotides that complement the original strand.

•  They need to recognize a primer to begin.  

1. the protein DNA polymerase  >>>>>>>  S phase.

4. the protein ligase  >>>>>>>  S phase.

                               ****************************************************

Through Meiosis, a diploid cell (2n) produces four haploid daughter cells (n).

After DNA replication there are two meiotic phases.

During prophase 1 of meiosis, each chromosome carefully pairs with its homologous chromosome.  

Crossing-over is the interchange of genetic information between two homologous chromosomes, making the daughter cells genetically different from the original one.  

The point where the interchange of genetic information occurs is the chiasma.  

5. the chiasma formation >>>>>>> propahase I

                          ****************************************************

Antiparallel microtubules between the separating chromosomes compose the spindle apparatus.

These fibers get elongated during the anaphase, while chromosomes or chromatids migrate to the opposite poles of the cell.

The depolarization of the microtubules drives the chromosomes or chromatids to segregate during the anaphase.

2. the depolymerization of the microtubules >>>>>> anaphase I and II

                          ****************************************************

Actin is a globular protein. Actin filaments are composed of the polymerization of the protein.

Among their many functions, actin polymers are involved in cytokinesis.

The final strangulation of the cytoplasm during the division process occurs through the organization of actin filaments.

Filaments form a ring structure, which progressively narrows its diameter until the complete separation of the two daughter cells.

3. the polymerization of actin >>>>>>> cytokenesis

Explanation:

Denaturation occurs when the protein deforms and loses its structure.

According to the question, A protein is exposed to extremely high heat, causing it to lose its secondary structure and be left with only its primary structure.

A protein becomes denatured when its normal shape gets deformed because some of the hydrogen bonds are broken.

Weak hydrogen bonds break when too much heat is applied or when they are exposed to an acid.

B. Mesozoic and Paleozoic eras ended with 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.

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.

d. endocytosis and exocytosis

Explanation:

These processes bring specific items in/out of the cell through active transport since the particles being brought in are generally large. Water for example, a much smaller particle, would use passive transport through the process of osmosis. Hope this helps!

Endocytosis and exocytosis are examples of active transport across the cell membrane.

Active transport is the movement of substances in and out of the cell through the membrane using energy and occurs against a concentration gradient.

An example is the endocytosis of the complex that is formed between receptor proteins of polypeptide or protein hormones at the level of the plasma membrane.

Insulin secretion is done in small pinocytosic vesicles that have insulin in colloidal dispersion, this secretion is in favor of a gradient, since insulin is more concentrated within the cell than in the extracellular space.

Therefore, we can conclude that endocytosis and exocytosis are examples of active transport across the cell membrane.
