Why is semi-conservative important

Biology
1 answer:
inn [45]3 years ago
6 0
The importance of the semi-conservative model is unhealthy old and new genes cancel each other. The result new cells are disease and mutation free. ... DNA replication is semiconservative because DNA is composed of two complementary strands, each of which acts as template to construct a new strand complementary to itself.

Answer: The correct answers are-

1) C) S Phase

2) A) prophase, metaphase, anaphase, telophase.

S phase ( synthesis phase) corresponds to the duplication of the genetic material (DNA). It takes place place after G1 ( Gap 1 phase) phase.

Answer:

BENEFITS:

The Descriptive investigation is used to describe a natural system when nothing or very little is known about the system. Like observing a new specimen in the microscope and describing it by observing the specimen.

A comparative analysis is used to compare two or more variable in nature by collecting data like observing the different colors of the rocks. It provides the data to show the similarity and dissimilarity of the population.

The Experimental investigation is used where experiments are performed to test and answer the scientific questions. The advantage is that data can be used as evidence for future research.

LIMITATIONS:

<u>descriptive  method  of  investigation </u>

It cannot be used to correct variable or be used to determine causes and  effect  of  the  problem

<u>experimental  method  of  investigation </u>

It might create an artificial situation that do not always represent the real  life situation

<u>comparative  method  of  investigation </u>

It  is not easy to control other variables that might influence the study

A tertiary consumer, such as a red-tailed hawk, receives what percent of the energy fixed by primary producers in a typical fiel
myrzilka [38]
Assuming a 10% trophic efficiency, the herbivore (primary consumer) will get 10% of the producer energy. Then, the second consumer that eat the herbivore will get 10% of the primary consumer energy, so it is 10%*10%= 1% of the primary producers.
Then, the t<span>ertiary consumer should get 0.1% of the primary producers' energy.</span>
