Answer:
A Origin
Explanation:
Sternocleidomastoid is the muscle found in the cervical and it’s the largest. It is responsible for the rotation and flexibility of the neck and is a very powerful and tissue-rich muscle.
The sternocleidomastoid muscle extends from the mastoid process of the temporal bone to the sternum and medial clavicle. When both sternocleidomastoid muscles contract, the head is flexed. The end of the muscle called ORIGIN connects to the sternum.
Answer: O cytoplasm: protects cell structures
Explanation:
Given what we know, we can confirm that the statement in the question is in fact true, by the end of the eighth week, the embryo is only 1 inch long and weighs just 1 gram.
<h3>What else do we know about the
embryo in this time frame?</h3>
During the first eight weeks, the embryo undergoes many changes. At this time:
- The legs and arms have formed.
- The fingers and toes are beginning to develop.
- It begins to be called a fetus.
- It is developing the lungs and lymphatic system.
- and much more.
Therefore, we can confirm that the statement that by the end of the eighth week, the embryo is only 1 inch long and weighs just 1 gram, is in fact true.

<span>Animal cells have a cleavage furrow which will pinch the cytoplasm into two nearly equal parts. While plant cells have a cell plate that forms halfway between the divided nuclei. Division of the cytoplasm to form two separate daughter cells. Plant cells divide by a cell plate that eventually becomes the cell wall. Cytoplasm and cell membranes are necessary for cytokinesis in both plants and animals.</span>
Answer:
Clean rooms are used for biological research in order to prevent the research from contamination of other microorganisms.
Explanation:
Rooms were cleaned before any biological research in order to reduce the intervention of other microorganisms in the research and made the research proof from any impurities. These labs have high atmospheric pressure which decline the growth of microbes and the research will be done in a better way.
