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
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.

Define gamete and zygote. What number of chromosomes does each have?
Answer:
gamete: a mature haploid male or female germ cell which is able to unite with another of the opposite sex in sexual reproduction to form a zygote. zygote:a diploid cell resulting from the fusion of two haploid gametes. zygote has 46 chromosomes, gamete has 23
Explanation:
Gel electrophoresis allows molecules to migrate along the gel at different rates by using:
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.

Which event will cause a protein to function incorrectly within a cel
А
A decrease in the amount of carbohydrates in the cell lowers the amount of available energy.
B A chemical causes the cell membrane to become more ridged to prevent water loss.
С A cell is exposed to a chemical that increases the rate at which RNA is produced.
An increase in the internal temperature of the cell changes the protein's shape.
Explain what happens to the egg following fertilization, make sure you use the word "cells" and "chromosomes" in your answer.
Please HELP!!!
Answer:
The fertilized egg stays in the fallopian tube for about 3 to 4 days. But within 24 hours of being fertilized, it starts dividing fast into many cells. It keeps dividing as it moves slowly through the fallopian tube to the uterus. Its next job is to attach to the lining of uterus.

Define gamete and zygote. What number of chromosomes does each have?
Answer:
Gametes (23) reproductive cell produced during meiosis that has the haploid number of chromosomes
Zygote (46) diploid cells
Which is a function of melosis?
Answer:
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction

somatic cells can also be called
Answer:
They are also called vegatal cells.
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.
what molecular process is occurring at a higher rate to result in an increase in lacz mrna?
Answer:
RNA Polymerase
Explanation: General transcription factors position RNA polymerase at the start of a protein-coding sequence and then release the polymerase to transcribe the mRNA. Activators enhance the interaction between RNA polymerase and a particular promoter, encouraging the expression of the gene.

howw does an acquired mutation in a somativ cell gene leading to cancer develipment affact a persons abilty
Answer:
Cells become cancer cells largely because of mutations in their genes. Often many mutations are needed before a cell becomes a cancer cell. The mutations may affect different genes that control cell growth and division. Some of these genes are called tumor suppressor genes.
