Black-footed ferrets are native to the Great Plains. They spend most of their
time underground in prairie dog burrows. Which factor would increase an
area's carrying capacity for black-footed ferrets?
A. Increased competition for space
B. Increased number of diseases
C. Increased number of predators
D. Increased availability of food
Answer:
D. Increased availability of food
Explanation:
Trust
The factor that would increase an area's carrying capacity for black-footed ferrets is the increased availability of food. The correct option is D.
What is carrying capacity?Carrying capacity is defined as the average population size of a species in a given habitat.
Environmental factors such as adequate food, shelter, water, and mates limit the species population size. If these requirements are not met, the population will decline until the resources recover.
If there is more food available in an area, more black-footed ferrets can survive and reproduce, increasing the species' carrying capacity.
Increased competition for space, more diseases, and more predators would all reduce the carrying capacity of black-footed ferrets by reducing the number of individuals that could survive and reproduce in the area.
Thus, the correct option is D.

You observe every fall that the trees in the forest lose their leaves, but by the following fall, the leaves have disappeared. The most accurate explanation for this observation would be:
The tree creates a layer known as the abscission layer, which prevents nutrients and water from reaching the tree and inhibits the growth of the leaves. Hormones in the trees cause the process of abscission.
What is abscission layer?Tiny tubules in the abscission layer are responsible for carrying carbohydrates back into the tree and delivering water to the leaf, flower, or fruit.
The amount of nutrients and water that pass through the tubes is decreased in the autumn because cells in the abscission start to expand and exude a waxy substance.
Abscission of leaves, which takes place in the fall, is the natural loss of an old leaf at the base of the petiole. Many physical and biochemical changes occur during leaf abscission, most of which are controlled by plant hormones.
Therefore, every fall that the trees in the forest lose their leaves.

A white blood cell (WBC) encounters bacteria in a scrape on the knee of a child who has fallen off of his bicycle. The WBC’s job is to take the bacteria inside of itself and destroy the bacteria. If the bacteria cannot be moved across the WBC membrane, how will the WBC most likely take it in?
Answer:
The correct answer is - phagocytosis.
Explanation:
Phagocytosis is a type of endocytosis that also engulfs the solid material including microbial pathogens like bacteria and others. In immunity response macrophages, neutrophils and. immature dendritic cells are white blood cells that perform the phagocytosis process to kill the microbes and antigens.
Phagocytosis ingests and digest pathogens and develops an adaptive immune response an essential part of the innate immune system. WBC will most likely take it in through phagocytosis in the given case.
2. Give one possible reason why the population decreased in 1990 after it had reached its
carrying capacity
1 I
Answer: The population exceeded its carrying capacity because there were more resources available so many deer reproduced and the population quickly exceeded the carrying capacity.
Explanation:
When the population size exceeds the carrying capacity, the population must decrease. One possible reason is the lack of available resources to support this population size.
What is Carrying Capacity?
A growing population that inhabits a limited space is gradually affected by density, rebounding in the multiplication rate.
The population growth per capita rate decreases as population size increases.
The population reaches a maximum point delimited by available resources, such as food or space. This point is known as the carrying capacity, K.
Carrying capacity refers to the maximum point at which the environment can support a growing population.
K is a constant. It coincides with the population size when natality rate and mortality rate are equal to each other. This is the equilibrium point.
If the population size, N, is inferior to K ⇒ the population still grow. When N approximates to K ⇒ the population's growth speed decreases. When N=K ⇒ the population reaches equilibrium, When N is superior to K (N>K) ⇒ the population must decrease in size because there are not enough resources to maintain that size.So when the population size exceeds K, carrying capacity makes the population decrease in size. This is because there are not enough resources for this population to survive.
Probably this population's size exceeded the carrying capacity because there were available resources and animals were not predated by any other species. So this population kept growing until they exceeded the carrying capacity level.
Once they did it, the environment could not support this population size, probably because of the lack of available resources, so the population had to decrease in size. Mortality rate must have increased while natality rate must have decreased.
One possible reason is the lack of available resources to sopport this population size.

2. Complete the following chart about the three main research projects
that led to the identification of DNA as the genetic material.
RESEARCHERS' NAMES
SUMMARY OF RESEARCH
SUMMARY OF CONCLUSIONS
Griffith
found a "transforming principle"
Avery
Hershey and Chase
identified the substance that phages inject
into bacteria
Answer:
Griffith's experiment, reported in 1928 by Frederick Griffith, was the first experiment suggesting that bacteria are capable of transferring genetic information through a process known as transformation. Griffith's findings were followed by research in the late 1930s and early 40s that isolated DNA as the material that communicated this genetic information.
Griffith's experiment discovering the "transforming principle" in pneumococcus bacteria.
Pneumonia was a serious cause of death in the wake of the post-WWI Spanish influenza pandemic, and Griffith was studying the possibility of creating a vaccine. Griffith used two strains of pneumococcus (Streptococcus pneumoniae) bacteria which infect mice – a type III-S (smooth) which was virulent, and a type II-R (rough) strain which was nonvirulent. The III-S strain synthesized a polysaccharide capsule that protected itself from the host's immune system, resulting in the death of the host, while the II-R strain did not have that protective capsule and was defeated by the host's immune system. A German bacteriologist, Fred Neufeld, had discovered the three pneumococcal types (Types I, II, and III) and discovered the quellung reaction to identify them in vitro. Until Griffith's experiment, bacteriologists believed that the types were fixed and unchangeable, from one generation to another.
In this experiment, bacteria from the III-S strain were killed by heat, and their remains were added to II-R strain bacteria. While neither alone harmed the mice, the combination was able to kill its host. Griffith was also able to isolate both live II-R and live III-S strains of pneumococcus from the blood of these dead mice. Griffith concluded that the type II-R had been "transformed" into the lethal III-S strain by a "transforming principle" that was somehow part of the dead III-S strain bacteria.
Completing the attached chart about the three main research projects ;
Griffith summary of research : Identified what R-strain bacteria took up from heat-killed S bacteria,Avery summary of research : Identified protein as not the transforming factorAvery summary of conclusion : Found a " transforming principle "Hershey and chase summary of conclusions : Found the " Infection and replication principle "All three researches were carried out to discover the genetic material ( DNA ) which is responsible for the transfer of genetic traits from parent cells to daughter cells.
Griffith research shows that bacterias can get there DNA ( genetic material ) through a process known as transformation and the experiment to prove this research was carried out by killing S bacterias through heat and then adding them to R-strain bacteria. Griffith observed and concluded that the Genetic materials of the S bacteria was taken up by the S -bacterias through a process known as " transforming principle "
During Avery research for the genetic material ( DNA ) Avery treated a mixture with DNA-destroying enzymes to see if the colonies of the mixture will transform but they failed to transform which proves that proteins are not the transforming factors and that DNA is the genetic material.
Hence we can conclude that Completing the attached chart about the three main research projects is as written above.

Answer:
The probability that their first child will both be ab/ab = 41%.
Explanation:
Available data:
Two linked genes (A) and (B) ⇒ 18 centiMorgans apartMan ⇒ Aa BbMan´s father ⇒ AA BBWoman ⇒ aabbThe recombination frequency is given by the distance between genes. We have to know that 1% of recombinations = 1 map unit = 1cm.
Recombination frequency = 0.18
Man: AaBb
Gametes) AB Parental
ab Parental
Ab Recombinant
aB recombinant
18 centi morgan = 18 % of recombination in total
= % aB + % Ab
= 9% aB + 9% Ab
100% - 18% = 82% of parental in total
= % of AB + % ab
= 41% AB + 41% ab
The frequency for each gamete is:
AB 41%
ab 41%
Ab 9%
aB 9%
