The Serengeti region of Africa contains a population of cheetahs and a population of lions. Studies have shown that the cheetah population has very low genetic diversity, while the genetic diversity of the lion population is quite high. The cheetah population is also much smaller than the lion population. Both populations are vulnerable to infection with a particular virus that can be fatal in both species. What is the most likely outcome if both populations are infected with this virus?
A.
The cheetah population is more likely to survive because there are fewer individuals for the virus to attack.
B.
The lion population is more likely to survive because larger populations are immune to viruses.
C.
The cheetah population is more likely to survive because lower genetic diversity increases immunity to viruses.
D.
The lion population is more likely to survive because it is more likely to have individuals with traits to combat the virus.
Answer:
D. The lion population is more likely to survive because it is more likely to have individuals with traits to combat the virus.
Explanation:
Since lions have greater genetic diversity it is likely that there's one or two lions that have a trait to resist or kill the virus thus won't be infected, whereas, since cheetah's have low genetic diversity and low population size it is likely that they have little to no chance to surviving this virus attack since the genetic makeup is similar among the members of cheetah species.

Use the rose experiment to answer the question. What are the independent and dependent variables?
Answer:
Independent Variable - Amount of Light;
Dependent Variable - Plant Growth;
Controlled Variables - temperature, soil, container, and humidity
Explanation:
Independent Variable - Amount of Light;
Dependent Variable - Plant Growth;
Controlled Variables - temperature, soil, container, and humidity
1. Plants need light for it growth and development. By studying photosynthesis and chlorophyll one can recognizes two factors: measure of light and development of a plant.
The adjustment in light influences the development of a plant. Both the two factors are measurable.
Cause-Independent Variable: measure of light
Impact Dependent Variable: development of plant
2. Plants have stems that become upward and roots that become descending. Become familiar with geotropism.
Answer:
The rose experiment is not a specific experiment but refers to a general example used to explain the concept of variables in an experiment. In this example, let's say we want to study the effect of fertilizer on the growth of roses.
The independent variable in this experiment is the fertilizer. It is the variable that is manipulated or changed by the experimenter. In other words, the experimenter decides how much fertilizer to apply to each group of roses.
The dependent variable in this experiment is the growth of the roses. It is the variable that is being measured and affected by the independent variable. In this case, the experimenter measures the height, number of leaves, and number of flowers for each group of roses, and this data is used to determine if the fertilizer had any effect on the growth of the roses.
Therefore, in the rose experiment, the independent variable is the amount of fertilizer applied to each group of roses, and the dependent variable is the growth of the roses, measured by their height, number of leaves, and number of flowers.

If one strand of DNA double helix has the following nucleotide sequence ATCGGTCAAGCTAGG what would the dna complementary stand read
Answer:
TAGCCAGTTCGATCC
Explanation:
In DNA, there are 4 different nucleotide bases. Adenine (A), Thymine (T), Cytosine (C) and Guanine (G).
A (adenine) always pairs with T(thymine) and C(cytosine) always pairs with G (guanine).
If we have the strand:
ATCGGTCAAGCTAGG
We have to pair A with T, and C with G. Therefore, the complementary strand of DNA will be:
TAGCCAGTTCGATCC
Explain the effect of temperature and pH on enzyme action.
Needs to be done ASAP.
Answer:
enzymes loose their form in both unsuitable ph and temprature.
Explanation:
at very high tempratures enzyme molecules denatures due to high speed movements, at low tempratures enzymes works too slow to be useful enough.
low ph solotions contain lot of H+ and high ph solutions have few H+ , and the number of these H+ ions have polar effects on enzymes. some Enzymes like pepsin works perfect in acidic environment ( ph=2) while others might work at high ph or average ph( like Trypsin works well at ph=7).
Are bats blind?Non scientific or scientific question?
Answer:
No, bats are not blind. Bats have small eyes with very sensitive vision, which helps them see in conditions we might consider pitch black. They don't have the sharp and colorful vision humans have, but they don't need that.

Which component of a DNA synthesis reaction is an enzyme?
Answer:
DNA polymerase
The enzyme that synthesizes DNA, DNA polymerase, can only add nucleotides to an already existing strand or primer of DNA or RNA that is base paired with the template. An enzyme, DNA polymerase, is required for the covalent joining of the incoming nucleotide to the primer.

Discuss the interconnections of the cardiovascular system with each of the other major body systems introduced. Give specific examples of these interactions and explain their effect on homeostatic balance.
The correct answer to this open question is the following.
The interconnections of the cardiovascular system with each of the other major body systems is of the utmost importance for the health of the human body. The circulatory system's main function is to take blood to all the cells of our body. The instant the heart stops bombing blood to all the cells, organs, glands, and systems, the body stops its vital functions. The Circulatory system has a direct relation to the optimal operation of other systems such as the Respiratory system, the Reproductive system, the Digestive system, the Skeletal system, the Muscular system, the Lymphatic system, the Nervous system, and the Endocrine system.

where has the population reached the carrying capacity in the Graph shown above? (need help quick!)
A. point C
B. point B
C. point A
D. point D
Answer:
The correct answer is option D. point D.
Explanation:
Carrying capacity is characterized as the maximum populace size that a domain can continue inconclusively. For most species, there are four factors that factor into figuring the carrying capacity of an individual population: food accessibility, water resources, habitat, and ecological conditions.
In a graph representation of population size in a time period increases until it reaches carrying capacity, carrying capacity is representing in the graph where the increase in curve becomes stable and makes a plateau.
Thus, the correct answer is option D. point D.

which components of dna determine the genetic code?
Answer:
Explanation:
Genetic code. Genetic code, the sequence of nucleotides in deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) that determines the amino acid sequence of proteins. Though the linear sequence of nucleotides in DNA contains the information for protein sequences, proteins are not made directly from DNA.

you are given a quadrat of 1.5 square meters and you count the
dandelions in 10 quadrats and find an average of 2 dandelions per quadrat
area. Use this information to estimate the population density of dandelions
per square meter in a 4500 square meter open field. (make your answer
just the number, round to the nearest 2 decimal places) *
Your answer
In a stable population of rabbits and wolves a government agency enacts a 1 point
Answer:
1.33 dandelions per square meters
Explanation:
The correct answer would be 1.33 dandelions per square meter of land.
Size of quadrat = 1.5 square meters
Average number of dandelions per quadrat = 2
Total study area = 4500 square meter
Population density = number of organisms per unit area
There were 2 dandelions per 1.5 square meters
How many would be per square meter?
= 2 x 1/1.5 = 1.3333 dandelion per square meters
To 2 decimal places = 1.33 per square meters

One function of the poly-A tail on eukaryotic MRNA sequences is to help the MRNA be transported from the nucleus to the cytoplasm. Prokaryotic mRNA also has a poly-A tail. Choose the best explanation of the prokaryotic poly-A tail.
Answer:
In eukaryotes, it is well known that polyadenylation is required to produce the mature messenger RNA (mRNA) molecule and it provides stability to the mRNA during translation initiation. In prokaryotic organisms, polyadenylation is required for the degradation of the mRNA in a mechanism that involves three steps: endonucleolytic cleavage, polyadenylation and exonucleolytic degradation. Moreover, it is also important to note that no evidence of polyadenylation has bee reported in some prokaryotes including the halophilic bacteria Haloferax volcanic (Slomovic et al. 2005).
