The capsid copies the host cell’s DNA is the role of the capsid play in viral reproduction.
The role capsid play in viral reproduction is that the capsid copies the host cell’s DNA. Thus, option C is correct.
What is reproduction?
Reproduction has been defined as the process carried out by the living organisms and during the process of reproduction the living organisms produces their own young ones and feed them. Reproduction has been the supreme quality of living things. The role capsid play in viral reproduction is that the capsid copies the host cell’s DNA.
There are two types of reproduction and these are sexual and asexual reproduction. The process of reproduction in which two parents are involved has been said to be sexual mode of reproduction and the process of reproduction in which only single parent has involved in known as asexual mode of reproduction. The example of asexual reproduction are budding, fragmentation, spore formation, and binary fission.
Therefore, The role capsid play in viral reproduction is that the capsid copies the host cell’s DNA. Thus, option C is correct.

13. A group of students want to investigate the effects of plant moisture on the growth of caterpillars. The
students fill three identical boxes with an equal number of a kind of leaf that caterpillars eat. The students
keep the leaves in the first box dry, spray the leaves in the second box with two sprays of water, and spray
the leaves in the third box with four sprays of water. The students then add four caterpillars to each box.
Every day the length of each caterpillar is measured and recorded, and the results are averaged. What is
the outcome/dependent variable in this experiment?
A. The number of leaves put in each box
B. The amount of water put on the leaves
C. The number of caterpillars in each box
D. The change in length of the caterpillars.
The outcome or dependent variable in this experiment is the change in length of the caterpillars, which is option D. As the students are investigating the effects of plant moisture on the growth of caterpillars, the growth of the caterpillars is the variable that they are measuring.
What are variables?In an experiment, there are two types of variables: independent variables and dependent variables. Independent variables are the factors that are manipulated or changed by the researcher, while dependent variables are the factors that are measured or observed in response to the changes in the independent variables. In the given experiment, the independent variable is the level of moisture applied to the leaves, which is varied across the three boxes. The dependent variable is the change in length of the caterpillars over time, which is measured and recorded every day.
Hence, the outcome or dependent variable in this experiment is the change in length of the caterpillars, which is in option D.

Explanation:
The experiment to visualize these microbes from an environmental sample will be:
Standard plate count- collect a water sample from environment diluted with 99 ml sterile water and placed it in Petri dishes with nutrient Agar, then incubate it . Then you can notice the colony of bacteria.Membrane filter technique: Collect 100 ml of water sample from the environment. Then passed through a cellulose filter called a membrane filter. Then filter pad is transferred to a bacteriological growth medium. Then you can notice the colony of bacteria.What are Prokaryotes?A prokaryote is a single-celled organism that lacks a nucleus, and other membrane-bound organelles.

On the Galapagos Islands, in the Pacific Ocean, live over a dozen species of small birds that are the same except for their beaks. Each species beak is a different size and shape. Birds with small, narrow beals ate either small seeds or insects. Birds with large beaks ate larger seeds. Based on the information in the passage, explain why there are two different beak sizes on the island. What will most likely happen to the finch population if the large seed plant becomes extinct.
Why would this happen? How can adaptations and natural selection help explain the reasoning for population changes in finches?
Answer:If the large seed plant becomes extinct the finches with larger beaks will probably die out thus reducing the finch population
2)This will happen as their source of food is gone and thus leaving them to either feed on what there not used to or die
3)im not too sure of this but this is what i think; In Darwin's finches, those that have short beaks turned out to be an adaptation that made them more suited into poking holes in the ground and feed on grubs. Also the drought reduced the number of seeds and finches with bigger beaks were able to eat the larger and harder seeds so more of them survived.

Hemophiliacs have blood that does not coagulate well, and they often die at a young age. The disease allele is recessive and X-linked. The normal allele (N) is completely dominant over the disease allele (n). If a hemophiliac woman and a non- hemophiliac (normal) man have children, what percentage of their sons would be expected to have the disease? What percentage of their daughters would be expected to have the disease?
Answer: 25 or 50 %?

A man and a woman marry and have four children with the following blood types: Type A, Type B, Type AB, and Type O. What are the genotypes of the parents? Hint: Work the problem backwards.
Answer:
the man would have type B blood
the women would have type A blood
Explanation:
In the given question, the genotype of the parents are :
- One parent is Heterozygous for A
- Other parent is heterozygous for B
What are the different Blood Groups?Blood is made up of Red Blood Cells, White Blood Cells and Plasma.
There are majorly four type of Blood Groups such as:
- Blood Group A
- Blood Group B
- Blood Group AB
- Blood Group O
Blood group AB doesn't contain any antibodies and thus they lack antigens and couldn't donate it to any other blood group.
Thus AB is a Universal Acceptor.
Blood Group O does not contain any antigen and thus it is the Universal donor.
What is a Genotype?Genotype simply means version of DNA sequence that an individual has. There is a large amount of variation in DNA sequencing among individuals and these sequencing when applied to an individual gene are called as genotype.
Genotype can also be used to refer to the alleles or variants an individual carries in a particular gene or genetic location.
The number of alleles an individual can have in a specific gene depends on the number of copies of each chromosome found in that species, also referred to as ploidy.
What are alleles?Allele is defined as the variant of a given gene.
In genetics it is normal for genes to show deviations or diversity and all alleles together make up the set of genetic information that defines a gene.
In the given question the genotype of the first child would be IAIO and for the second child it is IB IO. For the third child, it is IAIB and the fourth child would be having IO IO.
As children inherit one allele from each parent, these genotypes are possible only when the genotype of parents is IAIO i.e. heterozygous for A and IB IO heterozygous for B.
Thus one parent is Heterozygous for A and other parent is heterozygous for B.

Which of the following is not typically represented by pyramids in ecology? 30 points
- mass, - energy flow, - populations in ecology, - predator and prey relationships
The biomass pyramid shows the decline or steady decline in biomass from base to peak of each trophic level. Pyramids employed in ecological systems don't use fresh weight.
What is the role of biomass in ecological pyramids?The biomass that is produced by organisms at every trophic level can be measured using a biomass pyramid.
The bottom level of this pyramid is occupied by the producer, which are typically plants. Primary consumers come after the producers.
The total living biomass or organic matter present at various trophic levels in an ecosystem is represented by a biomass pyramid.
The mass of living things present at each trophic level in a given sample size is used to determine biomass. Calories per unit area or dry weight in grams are two ways to see it.
Therefore, biomass is not typically represented by pyramids in ecology.
