As a galaxy gets farther away from Earth, what happens?

Answers

Answer 1
Answer:

As a galaxy gets farther away from Earth it gets faster.

Explanation:

First, moving away “from the Earth”. They certainly aren’t going away from the Earth. Everything is moving apart from everything else. No matter where you are in this expanding world, everything else will seem to be dropping from you. The space in within the galaxies is expanding! And the farther away a universe is the more space there is to increase so the faster the galaxy appears to move away from us.
Answer 2
Answer: After the Big Bang happened, the universe is constantly expanding. The Universe has expanded for around 13.7 billion years. The further a galaxy is, the faster it would move away from Earth. This principle is called the conservation of momentum.

A cell forms glycogen from simple sugars when food is plentiful. Which statement describes this process?A It is a catabolic reaction that is endothermic.
B It is an anabolic reaction that is endothermic.
C It is a catabolic reaction that is exothermic.
D It is an anabolic reaction that is exothermic.

Answers

Answer: The correct answer is-

B It is an anabolic reaction that is endothermic.

A cell forms glycogen from simple sugars when food is plentiful. In human beings, carbohydrates ( glucose) are stored in the form of glycogen in muscles and adipose tissue.

The formation of glycogen from glucose is called as glycogenesis and it requires large amount of energy ( endothermic reaction) as a larger molecule is formed from simple glucose molecules, which shows an anabolic reaction.

Thus, option B) is the right answer.

What do bacteria have in common with the cells of other living organisms

Answers

Answer:

Bacteria and other living cells have some universal features that are, they are present in all the living cells.

These features include:

Plasma membrane: The lipid bilayer which separates the cell from the external environment. It is present in all the living organism.

Cytoplasm: It is a gel-like substance present within the plasma membrane of the cell (excluding nucleus). It contains and supports all the cell organelles and cell parts.

Ribosome: It is a vesicular structure made up of protein and ribosomal RNA. It is the main site of protein synthesis in all the cells. Prokaryotes generally contain 70S ribosomes and eukaryotes generally contain 80S ribosomes.

Genetic material: All the living organisms contains genetic material (usually DNA) either confined in the nucleus or floating freely in the cytoplasm.
They have ribosomes.They contain cytoplasm.
Some things bacteria have in common with cells of other livingorganisms is they both have chromosomes, they both have organellesand a nucleus, and are alive.
