In a 1973 essay with the same name, geneticist Theodosius Dobzhansky made famous the idea that nothing in biology makes sense except in the light of evolution. From a careful reading of The Serengeti Rules, one could also argue that nothing in biology makes sense except in the light of regulation. Do you agree or disagree with this claim
I agree with this claim because organisms interact with one another in an ecosystem, thereby regulating population sizes in the community.
The Serengeti Rules is a documentary film based on biologist Sean B. Carroll's book (2017). This book explains the balanced functioning of an ecosystem by exploring the discoveries of five pioneering scientists: Mary Power, Bob Paine, Tony Sinclair, John Terborgh, and Jim Estes.
The term 'Serengeti rules' is due to many of these rules were obtained by studying natural populations in the Serengeti National Park (Tanzania).
These rules are a set of simple ecological rules of nature that indicate how ecosystems work.
The Serengeti rules explain how organisms interact with one another in the ecosystem, thereby regulating population sizes in the community.
Some key concepts of the Serengeti rules are as follow: Keynote species is a type of species whose activities govern the wellbeing of other species in the ecosystem. A trophic cascade is a phenomenon by which species impact other species even when they do not directly interact with each other. Downgrading refers to cascading effect of the removal of a species at the top of a food web (e.g., predators)

b. Bobcats are another predator of snowshoe hare. If a population of bobcats immigrates to the
area, how is this likely to affect the habitat's carrying capacities for hare and lynx?
Answer:
Decrease population and carrying capacity.
Explanation:
If a population of bobcats immigrates to the area, the population of hare and lynx decreases that also affect the habitat's carrying capacities for hare and lynx because bobcats feed on both hare and lynx. Bobcats are very aggressive in nature, and has an aggressive hunting style. With these characteristics, the bobcats can hunt both hare and lynx which leads to decrease in population and carrying capacity.

Match the following description with the appropriate type of respiration:
a. occurs in the mitochondria
b. resting muscles depend on this type of respiration
c. lactic acid builds up in muscle fibers
d. rapidly produces ATP for short time periods
e. produces large quantities of ATP but takes longer to synthesize
1. anaerobic respiration
2. aerobic respiration
Answer:
The correct answer is -
1. c, and d.
2. a, b, and e.
Explanation:
Anaerobic respiration is the short and quick way of producing energy, however, it produces less amount of energy than aerobic respiration and produces lactic acid as a byproduct. It takes place in the cytoplasm of the cell and working or acting muscles depend on such respiration.
Aerobic respiration is the main and important respiration process that takes place in mitochondria and it takes time to produce ATPs that are much more than anaerobic respiration. Resting muscles get energy by this type of respiration.

A right circular cylinder with a ratio of surface area to volume equal to
2.1 m?
What results would you expect if these two models were compared in a
diffusion test?
A. The rate of diffusion would be slower for the right cylinder,
B. The rate of diffusion would be the same for the two models.
0
C. The rate of diffusion would be faster for the right cylinder.
D. The rate of diffusion would be faster for the sphere.
Answer:
the rate if diffusion will be faster in the right cylinder
Explanation:
The surface area to volume ratio of the cylinder is higher. This means that in the cylinder more reactants are exposed at the surface and the rate at which diffusion takes place increases
A genetically heterogeneous population of rice has a mean in the number of days to maturation of 30. Selection for decreased period of maturation is carried out for one generation. The average period to maturation among the plants selected as parents for the next generation is 25 days. F1 plants mature on average in 27 days. Estimate the narrow sense heritability.
Answer:
h² = 0.6
Explanation:
Before answering the question, we need to know a few concepts.
Artificial selection is the selecting practice of a specific group of organisms in a population -that carry the traits of interest- to be the parents of the following generations.
Parental individuals carrying phenotypic values of interest are selected from the whole population. These parents interbreed, and a new generation is produced.
The selection differential, SD, is the difference between the mean value of the trait in the population (X₀) and the mean value of the parents, (Xs). So,
SD = X₀ - Xs
Heritability in the strict sense, h², is the genetic component measure to which additive genetic variance contributes. The heritability might be used to determine how the population will respond to the selection done, R.
h² = R/SD
The response to selection (R) refers to the metric value gained from the cross between the selected parents. R can be calculated by multiplying the heritability h², with the selection differential, SD.
R = h²SD
R also equals the difference between the new generation phenotypic value (X₁) and the original population phenotypic value (X₀),
R = X₀ - X₁
-------------------------------------------------------------------------------------------------------------
Now that we know these concepts and how to calculate them, we can solve the proposed problem.
Available data:
You are selecting rice´s decreased period of maturation. The population of rice has a mean maturation time of 30 days → X₀ Parental selected average period to maturation is 25 days → Xs F1 plants mature on average in 27 days → X₁ N arrow sense Heritability → h²According to what we sow previously, we need to find out the value of h².
We know that h² = R/SD, so we need to get R and SD first.
R = X₁ - X₀
R = 27 - 30
R = -3
SD = Xs - X₀
SD = 25 - 30
SD = -5
Knowing this, we can calculate h²
h² = R/SD
h² = -3/-5
h² = 0.6

A. Household garbage
B. Industrial waste
C. Leftover art supplies
D. Yard trimmings
The reuse center might accept: D. Yard trimmings
What is a reuse center?
A reuse center, also known as a recycling center or a second-hand store, is a facility where various materials and items that are still in usable condition are collected, sorted, and made available for resale or redistribution. The main goal of a reuse center is to divert materials from the waste stream and promote their reuse, extending their lifespan and reducing the demand for new products.
These centers typically accept a wide range of items, such as furniture, appliances, clothing, electronics, books, toys, and more. By accepting and selling these items at affordable prices, reuse centers help reduce waste, conserve resources, and provide affordable options for individuals and communities.
A reuse center can accept yard trimmings as it include grass clippings, leaves, branches, and other organic waste from landscaping and gardening activities.

Sperm cells are not normally exposed to blood, but if they are, the immune system may produce ____________ against sperm cells' ____________ and render someone sterile.
Answer:
Sperm cells are not normally exposed to blood, but if they are, the immune system may produce __auto-antibodies__ against sperm cells' __auto-antigens_ and render someone sterile.
Explanation:
Auto-antibodies are antibodies that can destroy cells from the same organism. They are mistakenly directed against organs or tissues of the same organisms, causing auto-immune diseases or affections. The autoantibodies action occurs when the organism fails in recognizing its own cells and faces them as strange elements.
Auto-antigen is the molecule produces by the body that fails in being recognized due to a break up in the tolerance mechanisms, triggering an immune response.
In the exposed example, sperm cells do not usually mix with blood. So when they do, blood cells recognize them as strange bodies and act against them. Sterility might be an effect of this auto-immune response.

Guinea pigs can produce different coat colors, white, brown, and mixed white/brown (agouti). The allele B is codominant with allele W (white coat). Cross an agouti-colored Guinea pig with a brown Guinea pig. What are the odds of the offspring?
Answer:
Brown
Explanation:because the agouti itself is a mixture that remains of a pale brown color and the melanin content in the animals is in the darker colors so it is more likely that the brown color is predominant to the agouti due to the content of melanin that it
The descendants of a cross between an agouti heterozygous (AB) colored Guinea pig and a brown (BB) colored Guinea pig are half heterozygous agouti, half homozygous brown. The correct option is A.
What exactly is codominance?Codominance is a genetic effect that happens whenever the alleles are expressed in heterozygotes.
In this particular instance, allele B co-dominates with allele W, resulting in heterozygous (WB) colored Guinea pigs like one of the parents.

B. depressant.
C. stimulus.
D. response.
Answer:
D. Response
Explanation:
Basically, You Are Coordinating What Is Happening Which Triggers The Brain For A Response.
Answer:
D.
Explanation:
You are responding to the rain by closing the window.
- it is not an involuntary action because that is something that doesn't require thinking such as breathing and blinking.
- it is not a depressant because that is something that reduces functional activity - so affects the body.
- it is not a stimulus because a stimulus is a change or signal in the environment that can make an organism react. So, in this case the rain would be the stimulus.
