Assuming DNA is replicated correctly (so there are no mutations),

Biology
1 answer:
gavmur [86]3 years ago
7 0

Answer:

None of the choices would lead to all identical gametes.

Explanation:

Gametes are sex cells produced by sexually reproducing organims via a process of cell division called MEIOSIS. Meiosis is a cell division process which produces four (4) daughter cells (gametes), which are genetically different from the parent cell.

The difference in genetical content is as a result of a process unique to only meiosis called CROSSING-OVER OR RECOMBINATION. This process ensures that the genetic content of the gametes are altered. Hence, since gamete formation is done via meiosis, none of the scenarios in the option will lead to all identical gametes.

The coracobrachialis muscle originates on the __________.
Travka [436]

Answer:

Option C, coracoid process of the scapula

Explanation:

Coracobrachialis muscle is one of the essential muscles that is responsible for the movement of elbow along with biceps brachii and triceps muscles.  

The coracobrachialis arises from the coracoid process of the scapula. It assists the elbow in flexion and internal rotation. Musculocutaneous nerve passes through the Coracobrachialis muscle and terminates at the lateral end of the cutaneous nerve of the forearm. However, the Coracobrachialis terminates at the humerus and its medial surface

Hence, option C is correct

If humans had been present to build log structures during the Carboniferous period (though they were not!), which plant types wo
aliina [53]

Answer:

The plant types suitable during that period would be ferns, horsetails, and lycopods.

Explanation:

A geologic period and system, which covers 60 million years from the termination of the Devonian period to the start of the Permian period is known as the Carboniferous period. During the Carboniferous period, the plant life was luxuriant and extensive, mainly at the time of Pennsylvanian. It comprises ferns and fernlike trees, that is, the giant horsetails known as club mosses, calamites, or lycopods like Sigillaria and Lepidodendron.  

Thus, if humans had been present to construct log structures during the Carboniferous period, then they would have used logs of ferns, horsetails, and lycopods for construction work.
