Answer:
This question is incomplete as it lacks options, however, it will be answered BROADLY so the it can be understood enough to select the correct answer.
Please find the explanation below
Explanation:
Cells perform different functions and look differently because of the process of CELL DIFFERENTIATION. All cells arise from a single stem cell, which then gradually differentiates into different types of cells with different functions, as they divide.
At the molecular level, these different types of cells contain the same DNA sequence as rightly stated in the question. However, they look and perform differently because some of the genes are turned on while the others are turned off via the process of GENE EXPRESSION.
Therefore, a blood cell and skin cell possess exactly the same DNA sequence but look different and perform different functions because of CELL DIFFERENTIATION in which some genes on the DNA sequence are expressed and others are repressed. For example, in the blood cell; the genes coding for certain proteins found in blood are expressed while every other gene is silenced or inhibited. This allows those cells to perform only blood-related functions.
Answer:
c.
The rows of bushes
Explanation:
<em>The experimental unit in this experiment would be the rows of bushes in the field.</em>
<u>By definition, experimental units are considered physical entities that can randomly be assigned to varied treatment regimes during the course of a research.</u>
In this case, the entity that are given different treatment condition during the process of experimentation are the rows of berry bushes within one of the several fields. Half of the rows were covered with nets while the remaining half were left uncovered.
<em>The rows were given different treatments and hence, considered the experimental units in this particular experiment.</em>
The correct option is c.
The limited policies is the kind of health insurance policies that covers low frequency diseases.This policy only pay on event of certain occurrences as specified in the contract. It provide insurance for very narrow and specified risks.Example of dread disease policy can be purchased to cover specific disease as it is named in the policy.
Answer:
Increases
Explanation:
Biomagnification refers to a phenomenon in which the harmful toxic chemical gest magnified or amplified or increases in the food chain trophic level.
The biomagnification is caused by the bio-accumulation of the toxic material in the organisms.
The harmful toxic chemical enters the food chain through eating like when the crops are sprayed with pesticides and insecticides runoff in the water. From there the toxic material enters the aquatic food chain like from the planktons to fish and then to vultures.
The organisms at higher trophic level die because of the accumulation of the infected lower trophic organisms.
Thus, Increases is the correct answer.
