Which statement describes an important role of carbon dioxide in Earth's atmosphere?
Animals breathe carbon dioxide.
O Plants use carbon dioxide to make food.
O Carbon dioxido helps animals make proteins.
Carbon dioxide forms clouds that produce rain

Answers

Answer:Plants use carbon dioxide to make food

Explanation: Carbon-dioxide plays a very important role in sustaining life on Earth.

Plants use carbon-dioxide and water for photosynthesis in presence of sunlight and chlorophyll to produce food and oxygen.

CO₂ + H₂O →  O₂ + glucose (food)

This food is consumed by the animals and oxygen is used for respiration. Animals use energy from the food to do work and exhale back carbon-dioxide.

Gel electrophoresis allows molecules to migrate along the gel at different rates by using:

Answers

Answer:

Agarose gel or Pores in the gel

Explanation:

This question could have multiple answers because the gel has pores in it that allow smaller fragments of DNA to move faster through the pores because they're not getting stuck in the gel. Larger fragments of DNA get stuck in the gel as they try to fit through the large pores.

So, you could either say the agarose gel itslef or you could say the pores in the agarose gel allow the molecules to move at different rates.

Explanation:

Soma- in Latin, means (Body),

So, Somatic cell .. means a Body cell,

Generally, our body contains 2 types of cells according to number of chromosomes :

1- Somatic cells : - almost all body cells are somatic cells

- contain 46 chromosomes (diploid)

2- Germ cells : - only sperms in male & Eggs in female, are germ cells

- they contain 23 chromosomes (haploid)

- they are supposed to unite together (Egg & sperm) to form a diploid cell (23+23=46) ...that will eventually grow into a baby.
