B. Magma with high silica content.
I’m pretty sure
Answer:
All of these choices are correct.
Explanation:
Cell cycle is the process of growth and division of cell. It comprises of interphase and mitosis. In interphase the cell grows, replicates its genomic content and prepares itself for division. In mitosis the division occurs.
Cell cycle is controlled by a group of kinases called as Cyclin dependent Kinases (CDKs). They act by phosphorylating their substrates. They are of various types like Cdk1, Cdk2, Cdk4 etc. They become active when they bind to a regulatory protein called cyclin. They are also of various types like Cyclin A, Cyclin B, Cyclin C etc. Level of cyclin and corresponding CDK increases and decreases according to the stage of cell cycle. For example in S phase of cell cycle concentration of cyclin A and E shoots up. CDK2 is able to bind to these cyclin molecules and hence it becomes active.
Cell cycle has major checkpoints where the condition of cell is analysed before it proceeds to the next stage of cycle. If any abnormality is detected, repair mechanism is activated or the cell is killed. Checkpoints do not allow cell cycle to proceed in damaged cells.
p53 is a tumor suppressor protein which can halt cell cycle when it detects some abnormality in cell. It usually acts in G1/S checkpoint (before the DNA replication starts in cell) and G2/M checkpoint (before the cell division begins). Hence, all of the above statements are true.
Answer:
A and D I think
Explanation:
It's not erosion, so that is out of the answer choices. And I doubt it is crystallization, so that is why I think it is A and D. (correct me if I am wrong.)
Answer:
Answer. The more an experiment is repeated, with the same outcomes, the more biased it becomes
Explanation:
Gastropods are centrally flattened molluscs that move via muscle contractions.
<h3>What are gastropods?</h3>
Gastropods are invertebrates animal that belong to the phylum molluscs. Examples of gastropods are snails and slugs. The lol be in either salt water or freshwater or land. Their body parts include head,mantle, body mass and shell. They have muscular foot which help in movement through muscular contractions.
Therefore, Gastropods are centrally flattened molluscs that move via muscle contractions.
