Answers

the answer is B cause earth moon and sun combined together creates the greatest gravitational pull and makes tides.

Answer:

B. The interaction of Earth, the Moon, and the Sun

Explanation:

The gravitational attraction of the moon causes the oceans to bulge out in the direction of the moon.

Can someone please help me this question?The choices are:
A) move and capture food
B) create and exchange genetic material
C) Store and regulate water
D) make and store energy

Answers

Answer:

A) move and capture food

Explanation:

Amoeba is madeup of single cell and having a true nucleus or membrane around the nucleus. Amoeba belongs to kingdom protista because it has some characteristics of animals such as it can move from one place to another. Amoeba used phagocytosis which is a type of endocytosis in which large substances are entered into the cell. Pseudopod is part of amoeba body which is responsible for the movement and capturing the food.

The rough endoplasmic reticulum to created proteins that can be packaged in vesicles.

Answers

Answer:

After mature mRNA is created, it migrates to the cytoplasm then to the rough endoplasmic reticulum to create proteins that can be packaged in vesicles.

Explanation:

Translation is the process by which mRNA is decoded and translated to produce a polypeptide sequence, otherwise known as a protein. This method of synthesizing proteins is directed by the mRNA and accomplished with the help of a ribosome, a large complex of ribosomal RNAs (rRNAs) and proteins. In translation, a cell decodes the mRNA genetic message and assembles the brand-new polypeptide chain. Transfer RNA, or tRNA, translates the sequence of codons on the mRNA strand. The main function of tRNA is to transfer a free amino acid from the cytoplasm to a ribosome, where it is attached to the growing polypeptide chain. tRNAs continue to add amino acids to the growing end of the polypeptide chain until they reach a stop codon on the mRNA. The ribosome then releases the completed protein into the cell.
