Dominik [7]

1. shotgun

2. inbreeding

3. cloning

4. Y chromosomes

5. The Human Genome Project sought to map a human's entire genome.

6. Inbreeding is a type of selective breeding that occurs when individuals with similar characteristics continue to be bred in an attempt to keep a certain set of traits. However, inbred organisms are genetically similar, and the probability that members of the population will receive mutated alleles leading to disorders is high.

7. Since no two humans have the same DNA, except for identical twins, forensics can take advantage of this fact by using DNA fingerprinting to solve crimes, convict wrongdoers, or overturn unjust convictions.

slavikrds [6]

Answer:

The correct answer is - 6.8950.61 gm per mole

Explanation:

Given:

One form of hemoglobin is 0.324% Fe by mass

1 hemoglobin = 4 Fe

Solution:

Molar Mass of iron = 55.85

mass of 4 iron atom = 55.85 * 4 = 223.4 gms

0.324 % correspond to 223.4 gms

100 % correspond to = 223.4 *100/0.324

= 68950.61 gm

MM of haemoglobin = 68950.61 gms = 6.8 E4 gms

<u>Answer</u>: predator and prey

<u>Explanation</u>:

The described graph illustrates the cycle of a predator and prey population.  The population curves for predator and prey are not synchronized with each other and their amplitudes differ.

Changes in the prey population will not result in immediate or exactly identical changes in the predator population.

In the attached image, the red line represents the prey population and the blue the predator population. As it can be observed, when the prey population increases in size, the predator population size increases too.

However, this increase is not of the same size and is delayed in time. The predator population will continue to increase even though the prey population has started to decrease.

This has to do with the fact that the adult predators mated and gave birth when the food availability was still high. However, these new young individuals will not survive and reproduce due to decreasing prey. As the prey continues to decrease, more and more predators will perish.

The same cycle will then repeat over and over again.

A diploid cell has two pairs of homologous chromosomes. How many different combinations of chromosomes could there be in the gam
jonny [76]
Because there are 23 chromosomes in the haploid cells. Chromosomes from each haploid cell (sperm/egg) come together to from a diploid cell, meaning that the 23 chromosomes from the sperm have intermixed with 23 chromosomes in haploid cells of the egg so this is you answer hope this helped
