Answer:

The correct answer is blank1: quadrant sampling, and blank2: endangered.

Explanation:

A scientist needs to test her hypothesis she needs to perform an experiment or test and for a slow-moving animal (like snail or earthworm) quadratic sampling is a perfect method. The quadrate method uses a closed plot of land to find the vegetation of plant or population percentage of animals present in that land.

A decreasing population of animal could be endangered if the trend will not change.

Thus, The correct answer is blank1: quadrant sampling, and blank2: endangered.

sergejj [24]

The correct answer is A. Quantitative traits

Explanation:

In genetics, quantitative traits refer to traits or phenotypes (observable traits) that depend on many factors including multiple genes and actions in the environment. These traits differ from other traits because the traits tend to be more diverse in a population. In the case presented, the shell color in clams is an example of a quantitative trait because this phenotype is the result of three different each and each gene contains two alleles which means the color depends on many factors. Additionally, as most quantitative traits there is a higher variation in the phenotype considering clams can have different hues.

user100 [1]

Answer:

Chromatin helps regulate DNA replication.

Explanation:

Chromatin helps condense DNA strands to smaller units that can be easily managed during DNA replication and gene expression. This also prevents the breakage of the strands and facilitates equal distribution of chromosomes during cell division (during mitosis and meiosis).
