Genetic recombination would be most closely associated with which process in disease-causing microorganisms?

A.binary fission in fungi
B.sexual reproduction in fungi
C.spore formation in bacteria
D.viral replication in host cells

Answers

i think the answer is B because genetic diversity in sexually reproducing organisms can allow an organism to function in new ways

Genetic recombination is most closely associated with: Choice D: Viral replication in host cells

Definition:

Genetic recombination (otherwise termed genetic reshuffling) is simply the exchange of genetic material between different organisms which leads to production of offspring with combinations of traits that differ from those found in either parent.

In retroviruses, recombination actually occurs at the point during replication when the retrovirus genome is in a DNA form and takes place by the same break-rejoin technique as in cells and DNA viruses.

Recombination can occur both between two related retroviruses and between the retrovirus DNA and the host DNA.

Why is having many sense organs an advantage for an animal?

Answers

Sense organs allow animals to sense changes in the environment around them and in their bodies so that they can respond appropriately.They enable animals to avoid hostile environments,sense presence of predators and find food.

Faculties help all creatures arrange themselves in their surroundings, to discover food, to escape from risk, and to discover others of their own sort. Nonhuman creatures may have faculties that people don't have. For instance, most birds can see bright light while people can't.

Provide an example of how a genetic mutation could be positive, then explain how that mutation could cause a change in a population over time.

Answers

Q1: A genetic mutation can have a positive impact on a species as it can give them an advantage in survival in comparison to its counterpart that does NOT have that same mutation.
Q2: If this mutation has a positive impact on survival rates, it’ll be more common for the ones that have the mutation to reproduce rather than the ones that don’t. As time goes on the majority of the population will have this mutation, possibly changing it completely.

Answer: Some mutations happen during cell division, when DNA gets duplicated. But the mutations we hear about most often are the ones that cause disease. Some well-known inherited genetic disorders include cystic fibrosis, sickle cell anemia, Tay-Sachs disease, phenylketonuria and color-blindness, among many others.

A. They contain radioactive isotopes that decay at a constant rate.
B. They are made primarily of radioactive carbon that is easy to detect.
C. They give off radioactive isotopes when an electrical charge is applied.
D. They have been exposed to large amounts of radioactivity in the atmosphere.

Answers

Answer: I think the correct answer is A or B.

Explanation: But i highly suggest B

Radiocarbon dating is a feasibe method because the isotopes involved decay at a constant rate.

What is radiocarbon dating?

The term radiocarbon dating refers to the use of carbon in the establishment of the age of a sample. This is usually done by the use of carbon -14 isotope.

The reason why radiocarbon dating can be used to determine the accurate age of these items is that they contain radioactive isotopes that decay at a constant rate.

Refer to the figure below and match the angle with the correct measurement in degrees.

Answers

Answer:

Cool

Explanation:

The possible genotypes of the parental generation are as follows :

Male : Night Blindness Female : Normal

What is Genotype ?

Genotype is the collection of the the two alleles that makes up the gene inherited by an offspring from its parents.

Given that only one of the males of the first generation suffers from Night blindness, He inherited the Night blindness from the parental generation. therefore the male from the parental generation is a carrier of the Night blindness allele while the Female is not a carrier.

Hence we can conclude that The possible genotypes of the parental generation are Male : Night Blindness and Female : Normal.

There are several microorganisms all around us, they all come in different shapes and sizes. It might be quite difficult to identify one organism from the other. To solve this problem scientists came up with a method of naming and grouping microorganisms into different categories, this method is known as TAXONOMY.

Taxonomy is the method of classifying different organisms into various groups. The scientist that first came up with this method is known as Carl Linnaeus. The different categories include; kingdom, phylum, class, order, family, genus, species.

Hence scientists group similar organisms together through a process called TAXONOMY.

Each conditional jump may have one of two possible resolutions: either it will branch (i.e. the next instruction in the pipeline is the target of the jump) or it will not not branch (i.e. the next instruction in the pipeline is the instruction in the subsequent memory location after the conditional jump instruction).In all cases, if the next instruction is predicted wrong (a misprediction), it must be squashed from the pipeline, and the correct instruction fetched after a bubble. To avoid the penalty of frequent mispredictions, we want to choose the best possible branch predictor.In case of control hazards caused by a conditional jump instruction such as jeq, stalls can be reduced by using a branch predictor. In class, we discussed three kinds of branch predictors: Predict branch taken - After a conditional jump, the next instruction in the pipeline will the bethe target of the jump. Predict branch not taken - After a conditional jump, the next instruction in the pipeline will be the instruction at the subsequent memory address. Dynamic prediction - After a conditional jump, the next instruction will be chosen based on the resolution of the previous execution of the conditional jump. If there was no previous execution of the conditional jump, predict that the branch will not be taken.In answering the following questions about the above E20 program, assume that each misprediction results in a penalty of 3 clock cycles, occupied by a pipeline bubble while the correct instruction is executed. For the purposes of this exercise, you can ignore other hazards.(a) What will be the total misprediction penalty accrued in the above program, if it is run on a processor that always predicts branch taken? Justify your answer.(b) What will be the total misprediction penalty accrued in the above program, if it is run on a processor that always predicts branch not taken?
