Challenge question! Imagine the following situation. You receive a viral vector coronavirus vaccine that uses a specific adenovirus and your immune system mounts a strong immune response. At the same time, your friend receives an RNA coronavirus vaccine and also has a strong immune response. One year later a new coronavirus variant emerges and neither of the original vaccines protect people from this new variant.
A new viral vector vaccine is developed to the variant using the same adenovirus as before. In clinical trials, it is found that the new vaccine protects people that originally received the RNA coronavirus vaccine that your friend had but does not protect people that originally received the viral vector coronavirus vaccine that you had.
Question: Can you think of an explanation for why the new vaccine didn’t protect you, but did protect your friend?
Answer:
she took more care of her self and her immune system its more advance rather than the other person!
Explanation:
Due to being more careful meaningly taking care of not catching it, but also just cause you had it doesnt mean you're going to be carless "free" because you got the vaccine.
your friend could've been protected even though she had the vaccine she was not carless unlike the other person she thought about her actions.
You are breeding alligators to be reintroduced in the wild. One of the female alligators is albino. Would it be possible to get normal colored alligators from this female? Identify the genotypes of each individual and show your work in
the Punnett squares below.
Answer:
It is possible for normal coloured alligators to be produced. If the albino trait is recessive and normal is dominant, the male would need 1-2 dominant alleles to produce a normal coloured alligator. It is also possible for a normal coloured alligator to be produced if albino is dominant and normal is recessive. In this circumstance, the female must be h e t e r ozygous, but the male can be either h o m ozygous or h e t e r o zygous to produce normal coloured offspring.
First punnet square genotypes:
Female - albino
Male - albino/normal (can be either one)
Second punnet square genotypes:
Female - Normal
Male - albino/normal (can be either one)

The University of Illinois has been conducting one of the longest selection experiments, begun in 1896 by C.G. Hopkins. Researchers have been selecting for high corn oil content (as measured in % dry mass). Researchers select those plants with the highest corn oil content, and use only those individuals to seed the next generation. Here is a portion of actual data from their experiment:
1899 mean oil content in entire population: 5.65% dry mass
mean oil content of selected plants: 6.30% dry mass
1900 mean of oil content in entire population: 6.10% dry mass
Calculate the heritability of corn oil content (% dry mass). For full credit, show your work, including any equations used.
Answer:
0.725
Explanation:
This type of question is a concept of Narrow-sense Heritability and Artificial selection used by plant breeds.
So, heritability = R/S
where;
R = response to selection
S = selection differential
S further implies the difference in mean oil content between base population & selected population.
S = 5.65 - 6.30 = 0.65% ( where the negative sign are not regarded)
R implies the difference in mean oil content between the offspring or population after implementation of selection and the base population.
R = 6.10 - 5.65 = 0.45%
∴
Heritability = R/S = 0.45% / 0.6%
= 0.725
Thus; the heritability in the oil content of corn in the given set of population = 0.725.

#4-6-Base your answers to questions #4-6 on the information below and on your knowledge of biology. Five individuals had their pulses taken in beats per minute (bpm) before and after exercise. The data are shown in the chart below. 4. State one reason why an individual's pulse rate increased during exercise 5. Calculate the average pulse rate before exercise for this group, to the nearest tenth___________bpm . 6. State why the individuals in this group have different pulse rates before exercise *
Answer:
4. (answered below); 5. 66.2; 6. (answered below)
Explanation:
4. The individual's heart rate increased because the individual needs more oxygen supplied to their muscles so the heart has to pump the oxygenated blood through the body at a faster rate.
5. Take average of the number of the pulse before exercise:
(68 + 70 + 54 + 64 + 75) / 5 = 66.2
6. Different individuals are different sizes and are in different states of health. An individual who is more physically fit will have a slower rate rate because their heart muscle is "exercised" or worked more and pumps blood more efficiently.

Paleoclimatic analysis has generated a claim that there is a possible correlation between an extinction event around 29 million years ago that allowed grasslands to become abundant and the adaptive radiation of several groups of butterflies.
Which of the following proposes the best alternative hypothesis for the claim?
A- Climate analysis conducted by sampling pollen preserved in amber shows an increase in grass pollen 29 million years ago, but there is no significant difference between speciation rate, as well as species richness with regard to butterflies, before and after 29 million years ago.
B- Climate analysis conducted by sampling pollen preserved in amber shows an increase in grass pollen 29 million years ago, which indicates there was an increase in grasslands that correlates to an increase in butterfly speciation during the same time period.
C- There is a correlation between the rapid and wide-ranging decrease in species richness of insects in general 29 million years ago and the increase in species richness and diversity among the butterfly population during the same time period.
D- Evidence of rapid speciation among butterfly species 29 million years ago is evenly distributed among all environments of that period.

In the DNA double helix, archaic pairs with thymine and cytosine pairs with
guanine.
True or false?
Answer:
False
Explanation:
'Adenine' pairs with thymine and cytosine pairs with guanine in a DNA double helix.
It is false that in the DNA double helix, archaic pairs with thymine and cytosine pairs with guanine.
What is DNA double helix?In molecular biology, the structure created by double-stranded molecules of nucleic acids like DNA is referred to as a "double helix."
A nucleic acid complex's double helical structure develops as a result of its secondary structure and plays a crucial role in establishing its tertiary structure.
One of the four bases—adenine (A), cytosine (C), guanine (G), or thymine—is joined to each sugar (T).
Adenine forms chemical bonds with thymine while cytosine forms chemical bonds with guanine to join the two strands together.
A broad head, prominent supraorbital ridges (brow ridges), and the absence of a prominent chin are characteristics of archaics that set them apart from anatomically modern humans.
Thus, the given statement is false.

money supply and inappropriate government policies of economics fluctuations
Answer:
Both are responsible for the economics fluctuations.
Explanation:
Fluctuations occurs in the economic condition of a country due to the inappropriate polices of the government because polices of government has direct impact on the the growth of economy of a country whereas the money supply tells us the current status of the economy of a country. The money supply refers to the total value of money available in an economy at a specific time so we can conclude that both money supply and inappropriate government policies leads to the economics fluctuations of a country.

A The new species can create excess nutrients in the soil that can damage native species
The series can harminative anime and damage the ecosystem
Answer:
Due to lack of biological gent.
Explanation:
Introducing a new species to a new ecosystem often leads to a disaster because of the absence of bioagent for that species. Bioagent are those organisms which has the ability to control other organisms by feeding on them. A new species does not make problem in its old or original ecosystem due to the presence of controlling agents but in the new ecosystem there is no bioagent that can stop its growth so that's why sometimes the introduction of new species leads to a disaster.

Which characteristic of living things does a virus lack?
A. the ability to evolve
B. the use of a genetic code
C. the need for materials and energy
D. the ability to reproduce once in a host cell
Answer:
virus grow and reproduce only in the host cell. they evolve according to the environment condition accordingly time passes. they also use genetic code the answer is the need for material and energy
The characteristic of living things that is lacking in a virus can be the need for materials and energy. So the correct option is C.
What are viruses?
A virus is a contagious microorganism made up of a protein-coated piece of nucleic acid, usually DNA or RNA. A virus can't multiply by itself; it has to infect cells in order to utilize the host cell's components to generate copies of itself. A virus frequently causes harm to the host species by destroying the host organism in the process. AIDS, COVID-19, measles, and smallpox are well-known examples of viruses that cause human illness.
Viruses may infect people. But in reality, viruses infect a wide variety of creatures. For example, there are viruses that infect fungi and viruses that infect bacteria. By researching viruses that infect so many different species, we may learn a lot about just how viruses keep themselves alive.
That actually advances our understanding of human illness. However, the viruses that affect people make up a very small portion of all viruses. The viruses that infect bacteria and are frequently referred to as phages would have the greatest abundance. They have many of the same characteristics in common, yet they are far more numerous. The mechanisms by which viruses infect people will be thoroughly investigated in the future, as will any potential methods of preventing viral replication in human cells.
Therefore, the correct option is C.

Explain how and why natural selection has allowed species such as sharks and alligators to remain genetically stable for thousands of years.
Answer:
Stabilizing natural selection keeps gene frequencies constant in a population. The normal, most common traits are selected for and preserved so only a limited amount of evolution occurs and species can remain unchanged even over long periods of time.
Explanation:
A biological process called reproduction occurs when an organism creates young (offspring) of the same species.
What influence natural selection for survival of species?Gene frequencies in a population are maintained constant through stabilizing natural selection.
Because only a small amount of evolution takes place and the most typical, most prevalent features are preserved, species can persist unmodified even across very lengthy epochs.
It is among the most crucial traits shared by all living things. While not necessary for an individual's existence, reproduction is necessary for the survival of a whole species.
