Answer 2

The currently recognized classification scheme is the five - kingdom system.

The five kingdom classification involves the grouping of living organisms into classes such that organisms in each class share similar characteristics such as : reproductive process, homeostasis, growth, mode of nutrition, cell structure and so on.

The five kingdom classes include :

Kingdom Monera

Kingdom protista

Kingdom plantae

Immunization with the childhood DPT (diphtheria, pertussis, and tetanus) vaccine protects against subsequent exposure to tetanus by Group of answer choices generating tetanus-specific memory B cells. producing life-spanning antitetanus IgE antibodies. stimulating quick inflammation upon future exposure. preloading antigen-presenting cells. stopping isotype switching of B cells from IgM to IgA.

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.

Explanation:

because that is the 2nd decompers

B group would represent the decomposer organisms. Therefore, the correct option is B.

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.

In 1976, an outbreak of pulmonary infections among participants at an American Legion convention in Philadelphia led to the identification of a new disease, Legionnaire's disease. The bacterium responsible for the disease had never before been known to be pathogenic. From your knowledge of bacterial genetics, can you postulate how it might have acquired the ability to cause disease

Answers

Answer:

Evolution.

Explanation:

It might have acquired the ability to cause disease due to evolution. Due to evolution, the harmless bacteria can turn into infectious pathogens that cause diseases. Evolution is the change in the characteristics of a species over several generations due to the process of natural selection. This evolution in the bacteria occurs due to changing of environmental conditions which changes the genetic makeup of that harmless bacteria and turn into infectious pathogen.

It is the number of a particular species that an ecosystem can support. D.It is a process of chang during which species in a community are established or replaced.

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.

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
