When is the production of genetically identical offspring a disadvantage? Explain your reasoning.
Answer: In an unstable or unpredictable environment asexually-reproducing species may be at a disadvantage because all the offspring are genetically identical and may not have the genetic variation to survive in new or different conditions. In an unstable or unpredictable environment asexually-reproducing species may be at a disadvantage because all the offspring are genetically identical and may not have the genetic variation to survive in new or different conditions.
Explanation:
The correct answer for the given question about Asexual Reproduction is "Production of genetically identical offspring is a disadvantage in an unstable or unpredictable environment".
What is Asexual Reproduction?Asexual reproduction refers to a type of reproduction when a child is born to a single parent. The newly created people are clones of their parents since they have the same genetic and physical characteristics.Both multicellular and unicellular species can reproduce asexually. There will be no gamete fusion involved in this procedure, and the number of chromosomes will remain the same. With the exception of specific situations where there is a possibility that a rare mutation may occur, it will inherit the same genes as the parent.So we can conclude that as all of the offspring are genetically identical and could not have the genetic variation to thrive in novel or changing environments, asexually reproducing animals may be at a disadvantage in an unstable or unpredictable environment.

(c) Based on the data, describe the time period during which Chlorella approximates exponential growth. Based on
the data and assuming logistic growth, describe the time period during which the Chlorella population has reached
the carrying capacity of the culture. Based the data, calculate the growth rate per day for the 5-day period with
the greatest growth rate.
Populations that experience a logistic growth model depend on the density and available resources. A) 5 - 10 days. B) 25 - 30 days. C) 0.27 x 10⁶cells/mL/day
What is the logistic growth model?In a logistic growth model, the population growth depends on density. Natality and mortality depend on the population size, meaning that there is no independence between population growth and population density.
When a population grows in a limited space, density rises gradually and eventually affects the multiplication rate. The population per capita growth 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.
K is a constant that equals population size at the equilibrium point, in which the natality and the mortality rate get qual to each other.
Assuming that the population size is N, when
N<K, the population can still grow. N approximates to K, the population's growth speed decreases. N=K the population reaches equilibrium, N>K, the population must decrease in size because there are not enough resources to maintain that size.The sigmoid curve represents the logistic growth model.
In the example,
Between 0 and 5 days the population remains relatively stableBetween 5 and 10 days Chlorella approximates exponential growth.Between 10 and 20 days Chlorella experiences exponential growth. Between 20 and 25 days the population is near the K and decreases its growth rate.From 25 to 30 days, the population reached the equilibrium point, and got to stabilize.Time period during which Chlorella,
A) approximates exponential growth ⇒ Between 5 and 10 days
Between 10 and 20 days its already exponential growth.
B) has reached the carrying capacity of the culture ⇒ 25 to 30 days
Finally,
C) Growth rate per day for the 5-day period with the greatest growth rate.
First we need to figure out during which period Chlorella experiences the greatest growth rate. To do it, we just need to make the following substraction,
Growth rate per period = final concentration - initial concentration
Period 0-5 ⇒ 0.08 - 0.01 = 0.07Period 5-10 ⇒ 0.55 - 0.08 = 0.47Period 10-15 ⇒ 1.9 - 0.55 = 1.35Period 15-20 ⇒ 2.8 - 1.9 = 0.9Period 20-25 ⇒ 3.2 - 2.8 = 0.4Period 25-30 ⇒ 3.2 - 3.2 = 0Now we know that during the period from 10 to 15 days, the population experienced its greatest growth rate. But this rate is acchieved in 5 days. Now we need to find out the growth rate per day. So all we need to do, is to divide the result of the substraction per 5 days,
1.35 x 10⁶ / 5 days = 0.27 x 10⁶ cells/mL/day
The answer is 0.27 x 10⁶ cells/mL/day

Researchers allow bees to feed from a feeder located 500 meters due south of the hive for several days in a row. They then place a new feeder due south of the hive and place feeders in several other directions from the hive as well, but all are now 450 meters from the hive. They leave the original feeder empty. Next, they determine which feeders that new bees from the hive now visit. What information can they learn from this experiment alone
Answer:
they can learn if Bees are able to calculate distance and direction or if they simply stick to what they know.
Explanation:
From this experiment they can learn if Bees are able to calculate distance and direction or if they simply stick to what they know. Since they have been accustomed to feeding from the feeder that is south they may continue to do so, but since it is not the farthest from the hive and there are other feeders located closer they may chose the new feeder. If they do decide to change feeder, then it tells the researchers that the Bees are able to calculate the distance and know that the new feeders are closer, while which feeder they choose might give them information on how bees determine direction.

Name and give examples of 2 major types of mutations. What do they have in common? How are they different?
Answer:
The correct answer would be - Two major types of mutations are deletions and substitutions.
Explanation:
The two major types of mutations are deletion and substitution, other than these there are many more mutations that are categorized under gene mutations and chromosomal mutation.
The deletion mutation takes place in the conditions where the DNA deletes or missed copying the nucleotide in a new DNA molecule. This type of mutation can occur in one or more nucleotides. Whereas Substitution mutation occurs when there is a wrong nucleotide added to the DNA sequence or substitute with other.
Both could be deleterious and takes place at the nucleotide level. Both mutation depends on the number of nucleotide or the location of the mutation on the gene.

For the 2nd one with the bear: Thick coats on a bare will help provide warmth whenever they go to hybernate. Thin fur would leave room for freezing and wouldn't be able to help them maintain the proper body temperature.
The 3rd one with the clownfish: A round tail provides a bigger boost when swimming since it is able to push more water. A forked tail would create a gap when they swim so they would have to expend more energy than with a round tail.
The 4th one with the Finch: Since grubs live underground a thinner beak would be able to dig them out and stab them faster. This allows them to reach farther and get more food.

How does the color adaptation help fish residing in the coral reefs?
Answer:
Fish found in coral reefs also have bright coloring to help with mating or camouflage. Due to the wide variety of prey found in coral reefs, the fish have developed a generalized feeding structure to take advantage of the biodiversity. Lastly sessile animals, such as coral, have adapted toxins to keep away predators.
Explanation:
Answer:
Many fish have color patterns that help them blend in with their environment. This may allow the fish to avoid being seen by a predator. Some fish, such as the flat fishes (Pleuronectiforms) , can change their skin coloration to match the surrounding habitat. Fish can also have disruptive markings to hide body parts

1. Explain why the greenhouse effect is necessary but how an enhanced greenhouse effect can harm the planet.
2. Define global warming and explain what has caused the recent trend of warming that the earth is experiencing.
3. Explain why Earth's temperature is directly affected by the amount of greenhouse gases in the atmosphere.
4. Define carbon sequestration and explain how deep geologic burial of carbon works.
5 Describe the connection between fossil fuel burning, the melting of polar ice, and the rising of global sea levels.
Answer:
1. The enhanced greenhouse effect disrupts the Earth's climate equilibrium and has led to an increase in the global average surface temperatures.
2. Scientists attribute the global warming trend observed since the mid-20th century to the human expansion of the "greenhouse effect" 1 — warming that results when the atmosphere traps heat radiating from Earth toward space. Certain gases in the atmosphere block heat from escaping.
3. Greenhouse gases absorb some of the energy and trap it in the lower atmosphere. Less heat radiates into space, and Earth is warmer. ... Carbon dioxide, methane, water vapor, and nitrous oxide are naturally present in Earth's atmosphere.
4. Carbon sequestration is the process of capturing and storing atmospheric carbon dioxide. It is one method of reducing the amount of carbon dioxide in the atmosphere with the goal of reducing global climate change.
5. As climate change caused by burning fossil fuels drives temperatures higher, the ocean warms, causing it to expand. ... Scientists have found that water draining from melting glaciers and ice sheets in polar and mountain regions is now also contributing to this rise in sea levels.
Answer: 1. Necessary because it keeps heat in and keeps the planet at the right temperature for life.
It can harm the planet if more pollution occurs and the greenhouse gas effect traps too much heat and causes global warming. 2. Scientists attribute the global warming trend observed since the mid-20th century to the human expansion of the "greenhouse effect"1 — warming that results Greenhouse gases let the sun's light shine onto the Earth's surface, but they trap the heat that reflects back up into the atmosphere.
