Natural selection is not a contributor to genetic drift.

Genetic drift and natural selection are two mechanisms that can lead to changes in allele frequencies within a population. The main difference between the two is that genetic drift is a random process that occurs due to chance events, whereas natural selection is a non-random process that occurs due to the differential survival and reproduction of individuals based on their genetic makeup. Genetic drift can occur in any population size, but it is more pronounced in small populations. Natural selection, on the other hand, requires a population to have variation in traits and a mechanism by which certain traits are more favorable than others for survival and reproduction.

The labels are placed in the jars along with the specimens to make sure that they are not lost. Because fish are stored in 50% isopropyl alcohol, which disintegrates most types of paper, the labels have to be made of a special paper that does not disintegrate.

The following are the steps for preserving specimens for scientific study:

Euthanizing. Specimens should be killed in a way that leaves them uninjured and comfortable, in accordance with the Institutional Animal Care and Use Committee's best standards (IACUC).

Slitting and injection. Liquid preservatives must be injected or inserted through slits into the body cavities, limbs, and tail.

Fixing. While the specimens are still relaxed, place them on trays so that they harden in the right position.

Labeling. Each specimen should be accompanied by specific data, which should be either connected directly to the specimen or documented in a notebook with a number matching to a numbered tag affixed to the specimen.

Storage. After specimens have been properly positioned, they should be preserved in liquid preservative for at least several days before being allowed to remain in the liquid or moved to plastic bags for temporary storage.

The ratio of radioactive argon to radioactive potassium in a rock is measured using the potassium-argon dating method to establish the age of the rock.

The best method for dating a fossilized skull associated with Homo Erectus, a species that emerged around 1.9 million years ago, would likely be potassium-argon (K/A) dating of the supporting rock. By measuring the ratio of radioactive potassium to radioactive argon in the rock, the potassium-argon dating technique establishes the age of rocks. This dating technique is based on the radioactive potassium-40, which is present in minerals and rocks, decaying to radioactive argon-40 and calcium-40. From 4.3 billion years ago (the Earth's age) to around 100,000 years ago, potassium-argon dating is reliable. With present detection methods, only 0.0053% of the potassium-40 in a rock would have converted to argon-40 after 100,000 years.

Answer:Lactose and Lactase: Exploring Enzymes as Catalysts. Digestive enzymes help your body break down your food.

Explanation:

Site of conversion of chemical energy of glucose to ATP is depicted by part labelled as B in the figure which corresponds to mitochondria of the cell.

ATP is created through the cellular respiration of glucose. Glucose is completely oxidised to produce CO2 and water, which releases ATP-stored energy. One glucose molecule undergoes aerobic respiration, yielding 38 ATP molecules. Aerobic respiration occurs in the mitochondria and cytoplasm. Cellular respiration includes the processes of glycolysis, the Krebs cycle, and oxidative phosphorylation via the electron transport system. The site of this conversion is represented as the part B in the image.

Glycolysis is the term for the lysis or splitting of sugars. During glycolysis, one molecule of the 6-carbon chemical glucose is split into two molecules of 3-carbon pyruvic acid. Whether or whether the cytoplasm contains oxygen, this is a possibility. In sum, we have two pyruvic acid, two ATP, and two electron carrying NADH molecules.

.The reactive intermediate is an allylic carbocation.

The reactive intermediate adds to a double bond.

Both claims are true; during the biosynthesis of geranyl diphosphate, an intermediate called an allylic carbocation is formed, and it joins with a double bond to produce geranyl diphosphate.

Ionic species known as carbocations have a positive charge on the molecule's carbon atom. Typically, they develop as an intermediary during different chemical reactions. Steric hindrance and the +I impact of alkyl groups linked to the carbocation's C+ dictate the stability of carbocations .The positive charge is delocalized over the two terminal carbons because the conjugated allyl carbocation's actual structure is a mix of the two resonance structures. The allyl carbocation becomes more stable than a typical primary carbocation as a result of this delocalization.

A- The frequency of the dominant allele, D, is 0.27, and The frequency of individuals with dominant traits is 0.09. B-  the population is not in Hardy-Weinberg equilibrium.

A) The frequency of the dominant allele, D, is found by adding the number of individuals with the DD genotype (2100) and half the number of individuals with the Dd genotype (2450/2 = 1225) and dividing by the total number of individuals (2100 + 2450 + 450 = 5000). P(D) = (2100 + 1225) / 5000 = 0.81. The frequency of the recessive allele, d, is found by adding the number of individuals with the dd genotype (450) and half the number of individuals with the Dd genotype (2450/2 = 1225) and dividing by the total number of individuals (2100 + 2450 + 450 = 5000). P(d) = (450 + 1225) / 5000 = 0.27.

The frequency of individuals with dominant traits (black beaks) is found by adding the number of individuals with the DD genotype (2100) and the number of individuals with the Dd genotype (2450) and dividing by the total number of individuals (2100 + 2450 + 450 = 5000). P(DD + Dd) = (2100 + 2450) / 5000 = 0.93. The frequency of individuals with heterozygous traits is found by taking the number of individuals with the Dd genotype (2450) and dividing by the total number of individuals (2100 + 2450 + 450 = 5000). P(Dd) = 2450 / 5000 = 0.49. The frequency of individuals with recessive traits (yellow beaks) is found by taking the number of individuals with the dd genotype (450) and dividing by the total number of individuals (2100 + 2450 + 450 = 5000). P(dd) = 450 / 5000 = 0.09

B) The Hardy-Weinberg equilibrium states that the frequency of alleles in a population will remain constant from generation to generation in the absences of genetic drift, mutation, migration or selection. To be in Hardy-Weinberg equilibrium, the observed genotype frequencies must be equal to the expected genotype frequencies based on the allele frequencies. In this case, the observed genotype frequencies do not match the expected genotype frequencies based on the allele frequencies. Therefore, the population is not in Hardy-Weinberg equilibrium.

The correct option is (A): Receptor tyrosine kinase activity. A medication that precisely prevents the addition of phosphate groups to proteins would inhibit receptor tyrosine kinase activity.

Phosphorylation, or the addition of a phosphate group, regulates several proteins in the organism. Kinases are enzymes that add phosphate groups to protein substrates. Kinases phosphorylate their substrates by transferring the terminal phosphate group of ATP (or GTP). Phosphorylation, or the addition of a phosphate group, activates proteins. Protein phosphorylation happens in all living things. Proteins are deactivated via dephosphorylation, which is the removal of a phosphate group. Proteins can activate or suppress important cellular actions such as secretion as part of a hormone. A cell uses phosphorylation as a switch to turn on or off protein activity. Dimerization and phosphorylation are characteristics of receptor tyrosine kinase activation. Because intracellular receptors are present exclusively in target cells, lipid-soluble signaling chemicals such as aldosterone traverse the membranes of all cells but influence only target cells.

Dicot roots undergo secondary growth in two stages: a) the development and activity of the vascular cambium; and b) the development and activity of the cork cambium.

Between the xylem and phloem in roots is a collection of parenchymatous or sclerenchymatous cells known as conjunctive tissue. Within the body of the plant, xylem transmits sap and water, and phloem delivers organic food. These cells initiate the lateral roots and vascular cambium during the secondary growth. The pith is minute or barely noticeable. The lateral meristems, which are inactive in herbs or herbaceous plants, are responsible for the secondary growth of plants, which results in an increase in stem thickness.
