melomori [17]2 years ago
6 0

Answer:

Option A, Fixed quota models are risky because slight miscalculations can result in fish population extinction

Explanation:

Some of the major drawbacks of modelling fishing are as follows –  

a) The fixed quota model is very risky as a miniscule change in attributes can result into extinction of fish.  

b) On the other hand fixed effort harvesting can decrease the risk of fish population extinction

Hence, option A is correct

Mendel used single gene (or monohybrid) experiments to describe his law of segregation. He used _______ characters (or dihybrid)
allochka39001 [22]

Answer:

Law of Independent assortment

Explanation:

Gregor Mendel, who was regarded the father of Genetics, discovered principles that governs inheritance in his experiments. He discovered that the alleles of a gene will separate into gametes when he performed a crossed involving a single gene or character like height, pea color etc. He proposed his law of segregation based on this.

However, he considered two characters or genes in his cross, which he called a DIHYBRID cross. He discovered that the alleles of each different gene separates into gametes independently of one another i.e. without one gene influencing the other in each gamete. He called this principle his LAW OF INDEPENDENT ASSORTMENT.

He obtained a 9:3:3:1 phenotypic ratio for the F2 dihybrid offsprings which is only possible if each gamete equally likely contains two alleles of the two different genes in different combinations.

What technique did Hershey and Chase use in their experiment that led to the conclusion that DNA, not protein, was the genetic m
Olenka [21]

Answer:

They used radioactive labeling techniques to build two different types of phage.

Explanation:

In 1952, a set of experiments were carried out by American biochemists Alfred D. Hershey (1908-1997) and Martha Chase. They prepared two separate virus samples, one contained DNA labeled with a radioactive isotope and the other contained protein labeled with a different radioactive isotope. They grew the two types of viruses separately, infected bacteria with the two sets of phages and analyzed the bacteria for radioactivity. From the results obtained, Hershey and Chase concluded that the viral genetic material was DNA and not protein, reinforcing the observations previously made by Avery.

What are the products of Anaerobic Respiration in yeast?
8090 [49]

The products of anaerobic respiration in yeast are carbon dioxide and ethanol.

<h3>Anaerobic respiration</h3>

This refers to respiration in the absence of oxygen.

In the absence of oxygen, both the citric acid cycle and the electron transport chain cannot proceed. Thus, only glycolysis takes place.

The two pyruvate molecules produced in anaerobic respiration in yeast are converted to ethanol, instead.

A scientist wants to know wheter a particular cell is round or rectangular.How should the scientist observe the overall shape of
dezoksy [38]

Answer:

<em>The shape of a cell can easily be seen through a light microscope.</em>

Explanation:

A microscope can be defined as a device which is used to visualize things which are otherwise not visible to the naked eye. The shape of a cell can be seen even through a light microscope. For example, an animal cell can be seen to have a round shape under the light microscope, a plant cell will be seen rectangular under the light microscope.

Other microscopes such as the electron microscope can even show the organelles present inside the cell.
