Three types of macromolecules are mentioned in the video that are digested and ABSORBED in the small intestine. What do they all get absorbed into first?
Lacteals
Epithelial cells
Capillaries
Answers
Given what we know about the biology of the small intestine, we can confirm that the macromolecules are being absorbed into the "Epithelial cells".
The small intestine is in charge of absorbing the nutrients, which we require in order to survive and perform even the most basic metabolic processes, from the food that we ingest. In order to be able to perform this function, the cells in question have specialized epithelium which consists of Microvilli.
Microvilli can be thought of as membrane protrusions that serve to expand the surface area of the epithelial cells. This allows the cells to have a greater area through which to absorb nutrients such as the macromolecules mentioned.

3. Would you expect organisms belonging to the same class to have fewer structural characteristics in common than organisms belonging to the same order? Explain.
Answers
The organisms belonging to the same order will share more structural similarities than the organisms belonging to the same class. It is because order is a lower group in taxonomic classification.
What is taxonomy?Taxonomy is the systematic and scientific approach of grouping things based on their similarities. Taxonomy provides hierarchical classification of the things.
Taxonomy contains seven basic elements in which the organisms are grouped into. Species form the unit level of taxonomy. Genus, family, order, class, phylum and kingdom of an organism is included. Kingdom is considered as a superior and diverse group of taxonomy.

using the information provided under the tables, calculate Fst for each species
what do these values for Fst tell you about geographic population subdivision in each species? Briefly explain your reasoning.
Answers
The Fst statistic reveals the degree of genetic variation between populations. If Fst is high, it indicates significant geographic population subdivision, while if it is low, it indicates little geographic population subdivision. As a result, Species A has significant population divergence in comparison to Species B.

The observed allele frequencies (p and q) and the expected heterozygote frequencies (2pq, assuming Hardy-Weinberg equilibrium) for Location 1 + 2:
Species A Observed allele frequencies: p=0.55 q=0.45
Expected heterozygote frequencies: 2pq = 2(0.55)(0.45)

calculation: Fst is the proportion of genetic variation present among populations, and it is calculated by dividing the genetic variation between populations by the total genetic variation.
Fst = Fst = (Ht - Hs) / Ht
Species A: Fst = [0.495 − ((0.42 + 0.32) / 2)] / 0.495
Fst = 0.1767

The Fst value is high in Species A and low in Species B. Species A shows a high Fst value (0.1767), which indicates a significant geographic population subdivision in this species. The low Fst value (0.0000) in Species B implies that there is little geographic population subdivision in this species.

Which immune cells are activated first when suspicious cells are identified in the blood stream?
a. T cells
b. Kinins
c. Phagocytes
d. B cells
Answers
Option c is Correct. When suspicious cells are found in the blood stream, phagocyte immune cells are the first to become active.
The innate immune system's neutrophils are regarded as the initial defense. The blood is carried by neutrophils and macrophages, which remain in tissues and keep an eye out for any concerns. Both cells have the ability to "eat" bacteria and, in the event of a problem, to interact with other immune cells.
Due to IgM's ability to be expressed without isotype switching, it is always the first antibody to be produced in a humoral immune response. Neutrophils play a crucial role in the initial response to injury because they act as the body's initial line of defense against microbes within 10 minutes of the injury. These early IgM antibodies are created before somatic hypermutation of B cells, which is why they tend.

Phenotype percentages can also be affected by factors, such as environmental influences or interactions between different genes.
What is Phenotype percentages?The phenotype percentages refer to the frequencies of observable traits or characteristics that result from the expression of genes in an organism. The specific percentages of phenotypes that occur in a population can vary depending on the genetic makeup and environmental factors.
For example, if a gene for eye color has two alleles, one for brown eyes and one for blue eyes, and the brown allele is dominant over the blue allele, then the phenotype percentages in the offspring of two heterozygous parents (Bb x Bb) would be:
75% brown-eyed
25% blue-eyed
This is because the offspring could inherit either a brown allele from one parent and a brown allele from the other parent (resulting in brown eyes), a brown allele from one parent and a blue allele from the other parent (still resulting in brown eyes), or a blue allele from each parent (resulting in blue eyes).

The correct response regarding the relationship between photosynthesis and cellular respiration is option B. The products of cellular respiration are the reactants of photosynthesis.
Photosynthesis and cellular respiration are two essential processes in autotrophs. These processes are opposite to each other as photosynthesis is an anabolic and respiration is a catabolic process.
In photosynthesis, carbon dioxide and water are reactants that are combined to form glucose. Light energy is stored in chemical energy in this process. In cellular respiration, glucose is oxidized in presence of oxygen and produces water and carbon dioxide as products, and releasing ATP is released as the source of energy.Thus, the correct answer is - option B. The products of cellular respiration are the reactants of photosynthesis.

Answers
If replication were conservative, the chromosomes labeled in the Meselson Stahl experiment would look like option (d): Parental generation H-H, first generation ½ H-H and ½ L-L, second generation ¼ H-H and ¾ L-L.
1. Parental generation: The original DNA molecule has both strands labeled with heavy nitrogen (15N), so it is represented as H-H.
2. First generation: If replication is conservative, the new DNA molecules formed will have one molecule with both parental strands (H-H) and another with both newly synthesized strands (L-L). Thus, the first generation consists of ½ H-H and ½ L-L.
3. Second generation: After another round of conservative replication, the parental H-H molecule will produce another H-H molecule, while the L-L molecule will produce another L-L molecule. In the second generation, we have ¼ H-H (1 H-H molecule out of 4) and ¾ L-L (3 L-L molecules out of 4).
Summary: In the Meselson Stahl experiment, if replication were conservative, the chromosomes would be labeled as follows: Parental generation H-H, first generation ½ H-H and ½ L-L, and second generation ¼ H-H and ¾ L-L.
