Birds are the main predators of these beetles; they hunt the beetles by sight and pick them up off of the tree bark where they feed. A logging company clears the trees off of the island and plants younger trees as a replacement. Trees with light bark are planted on one side of the island and trees with dark bark are planted on the other side of the island. What do you predict would happen to the range of coloration in the populations of beetles on each side of the island?

Select TWO answers, one to represent the beetles living on the light colored trees and one to represent the beetles living on the dark colored trees. (2 points)

A. graph 2 below

B. graph 3 below

C. graph 4 below

D. graph 5 below

Answer:

B. graph 3 below

D. graph 5 below

Explanation:

The original population of beetles (Graph 1) shows that most individuals had an intermediate phenotype between dark and light color. The graph expresses its highest point in the middle of the phenotypic ax, while the curve´s tails coincide with light and dark colors.

Probably, most of the trees inhabiting the whole island had some darkish color tone, which beetles used to camouflage and avoid predation.

When the company cleared the area and reforested, they planted light trees on one half and dark trees on the other half of the island. This change in the environment modeled the beetled phenotype, together with predation pressure.

If we consider the whole original population, we should say that it went under a disruptive selection. But if we think about the sides of the island separately, we could say that the population living on each side went under directional selection. We are not thinking about the whole population of beetled inhabiting the whole island, but two groups inhabiting each side of the island.

Graph 3 represents the beetles inhabiting the part of the land with dark trees. The population went under directional selection, and most of them turned into dark-colored to camouflage with the substrate in which they live.Graph 5 represents the beetles inhabiting the other part of the land with light trees. The population went under directional selection, and most of them became light-colored to camouflage with the substrate in which they live.

Answers

Answer:

generating tetanus-specific memory B cells

Explanation:

Memory B cells are cells of the immune system that produce antibodies against specific antigens present in pathogenic organisms. The B lymphocyte cells produce clonal memory B cells after the first exposure to the antigen, a process known as clonal selection. Subsequently, memory B cells that circulate in the bloodstream trigger a rapid secondary immune response (after a second exposure to the antigen) by producing antibodies against specific antigens that activated their parent B cell. Moreover, the DPT vaccine includes purified tetanus toxins (i.e., target antigens) that induce clonal expansion in specific B cells, thereby generating a population of memory B cells that produce specific antibodies rapidly in secondary immune responses.

Elements in the same column of the periodic table of the elements all
A. have the same number of protons.
B. share the same atomic structure.
C. have similar physical characteristics.
D. share the same number of neutrons

Answers

Answer:

C

Explanation:

elements in the same column have different number of protons and different number of neutrons.

Elements in the same column of the periodic table of elements all share the same atomic structure. Thus, the correct option for this question is B.

What is the similarity in the elements that belong to the same column?

Each column is called a group. The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements.

The number of protons governs the atomic number of an element. So, elements never have the same number of protons. The number of neutrons along with protons governs the atomic mass of an element which also never remains the same.

The physical characteristics of any element depend on the majority of the attributes. So, it may also vary from element to element.

Therefore, elements in the same column of the periodic table of elements all share the same atomic structure. Thus, the correct option for this question is B.

Explanation:

A fish maintains its depth in fresh water by adjusting the air content of porous bone or air sacs to make its average density the same as that of the water. Suppose that with its air sacs collapsed, a fish has a density of 1.18 g/cm3. To what fraction of its expanded body volume must the fish inflate the air sacs to reduce its density to that of water?

Answers

Answer:

0.153

Explanation:

We know the up-thrust on the fish, U = weight of water displaced = weight of fish + weight of air in air sacs.

So ρVg = ρ'V'g + ρ'V"g where ρ = density of water = 1 g/cm³, V = volume of water displaced, g = acceleration due to gravity, ρ'= density of fish = 1.18 g/cm³, V' = initial volume of fish, ρ"= density of air = 0.0012 g/cm³ and V" = volume of expanded air sac.

ρVg = ρ'V'g + ρ"V"g

ρV = ρ'V'g + ρ"V"

Its new body volume = volume of water displaced, V = V' + V"

ρ(V' + V") = ρ'V' + ρ"V"

ρV' + ρV" = ρ'V' + ρ"V"

ρV' - ρ"V'  = ρ'V" - ρV"

(ρ - ρ")V'  = (ρ' - ρ)V"

V'/V" = (ρ - ρ")/(ρ' - ρ)

= (1 g/cm³ - 0.0012 g/cm³)/(1.18 g/cm³ - 1 g/cm³)

= (0.9988 g/cm³ ÷ 0.18 g/cm³)

V'/V" = 5.55

Since V = V' + V"

V' = V - V"

(V - V")/V" = 5.55

V/V" - V"/V" = 5.55

V/V" - 1 = 5.55

V/V" = 5.55 + 1

V/V" = 6.55

V"/V = 1/6.55

V"/V = 0.153

So, the fish must inflate its air sacs to 0.153 of its expanded body volume

What are Decomposers?

Decomposers are organisms that convert decaying organic matter into more basic components. They are an important component of the nutrition cycle because they convert complex chemical substances, such as nitrogen and carbon, into direct nutrients that can be absorbed by plants and other living things.

Some species of bacteria, fungi and insects are specialized decomposers. These organisms are essential to maintaining healthy soil because they aid in the recycling of nutrients and the breakdown of organic matter, which would otherwise build up and cause nutrient imbalances. Decomposers, which break down dead organisms and aid in the containment of pathogens, may be important in disease prevention.

Therefore, the correct option is B.

Answers

Answer:

Cytotoxic T cell - kills infected human cells after recognizing antigens displayed on MHC class 1 B.

Helper T cell - does not directly kill microbes; after recognition of a specific antigen displayed on MHC Class 2, it secretes molecules that help other cells to do so.

B cell - phagocytoses microbes after recognizing specific antigens; secretes antibodies

Natural Killer Cell - kills virus-infected human cells by releasing perforin and granzymes.

Macrophage - Phagocytoses microbes after recognizing PAMPs; acts as an Antigen Presenting Cell to activate another type of immune cell

Mast Cell - Does not directly kill microbes; secretes histamine to initiate an inflammatory response.

Explanation:

T cell are immune-response cells that originate in the bone marrow but migrate and develop in the thymus gland. They are of two classes; Cytotoxic T cells and Helper T cells.

Cytotoxic T cell - kills infected human cells after recognizing antigens displayed on MHC (Major histocompatibility complex) class 1 B.

Helper T cell - does not directly kill microbes; after recognition of a specific antigen displayed on MHC Class 2, it secretes molecules that help other cells to do so.

B cells are formed and develop in the bone marrow. They make antibodies against antigens, and phagocytoses microbes after recognizing specific antigen.

Natural Killer Cells are cytotoxic lymphocytes of the innate immune system. They kill virus-infected human cells by releasing perforin and granzymes.

Macrophages are a type of white blood cells that detects and phagocytoses microbes after recognizing PAMPs (Pathogen-associated molecular pattern) They also act as Antigen Presenting Cell (APCs) to activate another type of immune cell

Mast Cells are cells found in the connctive and they function as part of the immune system of the body. They do not directly kill microbes. They secrete histamine to initiate an inflammatory response.

Answers

Answer:

D. It is a process of change during which species in a community are established or replaced

Explanation:

Ecological succession is a process that occurs when a community is being established or replaced.

It shows the change in community over time, focusing on the types of plants and the maturity of plants that are in the community.

Primary and secondary succession are the two types of succession. Primary succession shows the process of change in the establishment of a community. Secondary succession shows the change when a community is being replaced.

So, the correct answer is D. It is a process of change during which species in a community are established or replaced

There is a population of alien dogs, species Dogus Cute-ee-us, that live on the planet Woof. Their genomes and biology are amazingly identical to the genomes and biology of earth dogs. Consider a di-hybrid cross, where the first locus has alleles A and a, and second locus has alleles B and b. Each additional copy of either an A or B allele in the two-locus genotype increases the friendliness of the dog. Friendliness is measured by the Wilcoxon-Canus Amicus Diagnostic Scale (WCADS). There are five categories:

0 = Unfriendly/Loner (although not aggressive);
1 = Somewhat friendly/shy;
2 = Friendly;
3 = Very friendly;
4 = Maximally friendly.

For example, an alien dog with a two-locus genotype of Aabb would have a Somewhat friendly/shy behavior, since there is one copy of A and zero copies of B, adding to a score of 1 for the WCADS. Similarly, an alien dog with a two-locus genotype of AaBB has a Very friendly behavior (one copy of A + two copies of B = three copies total of A or B).

In the following mating: AaBb x AaBb, what is the expected ratio of Maximally friendly:Very friendly:Friendly:Somewhat friendly:Unfriendly alien dogs in the offspring, assuming the parents produce a very large litter?

a. 0:1:1:1:0
b. 1:2:3:2:1
c. 1:4:6:4:1
d. 9:3:3:1

Answers

Answer:

c. 1:4:6:4:1

Explanation:

The term quantitative heritability refers to the transmission of a phenotypic trait in which expression depends on the additive effect of a series of genes.  

Polygenic heritability occurs when a trait results from the interaction of more than one gene. And these genes can also have more than two alleles. The action of many genes and alleles can cause many different combinations that are the reason for genotypic graduation.  

Quantitative traits are those that can be measure, such as longitude, weight, eggs laid per female, among others. In the exposed example, the measurable trait is the dog´s friendliness. These characters do not group individuals by any precise and clear categories. Instead, they group individuals in many different categories that depend on how the genes were intercrossed and distributed during meiosis. The result depends on the magnitude in which each allele contributes to the final phenotype and genotype. When they interact, they create a gradation in phenotypes, according to the level of contribution.  

In the exposed example, each dominant allele contributes with a higher level of friendliness.    

aabb → 0 = Unfriendly/Loner (although not aggressive); Aabb, aaBb → 1 = Somewhat friendly/shy; AAbb, AaBb, aaBB → 2 = Friendly; AABb, aABB → 3 = Very friendly; AABB → 4 = Maximally friendly.
