Answer: C the cruciate and collateral

Explanation:

- Anterior cruciate ligament (ACL) - The ligament, located in the center of the knee, that controls rotation and forward movement of the tibia (shin bone).

- Posterior cruciate ligament (PCL) - The ligament, located in the center of the knee, that controls backward movement of the tibia (shin bone).

- Medial collateral ligament (MCL) - The ligament that gives stability to the inner knee.

- Lateral collateral ligament (LCL) - The ligament that gives stability to the outer knee.

Identify the isolation mechanisms described using the drop-down menus. Differences in courtship or other behaviors prevent matin
lana [24]

Answer:

First, let's add the missing piece of information

Identify the isolation mechanisms by labeling either Geographical, Behavioral, Temporal, or Anatomical from the drop-down menu

The correctly identified mechanism is

1. Behavioral

2. Geographical

3. Temporal

4. Antomical

Explanation:

Differences in courtship or other behaviors prevent mating.- our answer is Behavioral

(Behavior isolation is the term used to describe reproductive isolation as a result of variations in courtship behaviours between the members of the same species occupying the same region).

Species can no longer interact because they are separated by physical boundaries.- it is Geographical

(Geographic isolation is seen in situations where the two populations of the same species get isolated by a geographical barrier such as mountain, island or river. This results in an inability to breed between the two populations as they become distinct new species).

Species do not interbreed because they breed at different times. this is definately Temporal.

(Temporal isolation is a form of reproductive isolation due to mating at separate times and seasons among two populations of the same species).

Species cannot physically mate due to genitalia or gametes being incompatible. And the correct answer is Antomical.

(Anatomical isolation

It is observed in situations when two populations of the same or distinct species cannot interbreed due to physical features such as genitalia and gametes formed in the organisms that make them uniquely separated).

Yes! this is the right answer. I just solved this question and its CORRECT.

Secretion of human chorionic gonadotropin (hcg) occurs during what time frame during pregnancy?
masha68 [24]
Secretion of human chorionic gonadotropin [HCG] only occur during pregnancy in the placenta. The concentration of this hormone increase rapidly during the first three months of pregnancy; the amount in the blood stream doubles every two to three days as the development of the placenta and embryo progress. The hormone reaches its maximum concentration peak around the sixth week of pregnancy and after this, its concentration decline.

C

Asexual reproduction does not produce variety in population, unless through mutations, because offspring are exact copies of their parent – because they reproduce by binary fission.

Explanation:

Sexual reproduction produces variations by genetic combinations. Remember during meiosis, there is the crossing over of chromosomes. In addition during fertilization, in sexual reproduction, each gamete brings in alternative forms of alleles of genes.  The advantage of asexual reproduction is that it allows for fast reproduction because only one parent is involved in the formation of offspring.
