mrs_skeptik [129]4 years ago
4 0

<u>Answer:</u>

Area receives little precipitation.

<u>Explanation:</u>

  • Arid climate is a type of climate that receives less than 25.4 cm of rainfall throughout the year.
  • Desert climate is called as arid climates. Rainfall in arid climates is usually irregular but when rainfall occurs then it will be huge with thunderstorm.
  • Many plants and animals found in that climate adopt themselves from rare rainfall and they remain inactive during most of time of the year and active only on the time when rainfall occurs.

How do the circulatory and respiratory systems work together to get oxygen to the body cells?
svetoff [14.1K]
When we breathe, our respiratory system takes up oxygen and carbon dioxide or other useless gases go out . The oxygen combines with the haemoglobin in the blood of the circulatory system . This is transferred to all the cells of our body to get energy.

What is the probability that a cross between a true-breeding pea plant with spherical seeds and a true-breeding pea plant with w
notsponge [240]

Answer:

1 or 100%

Explanation:

Let the allele for seed shape be represented by S.

True breeding spherical shape seeded pea plant will have SS as genotype

True breeding pea plant with wrinkled seeds will have ss as genotype

Crossing the two:     SS  x   ss

Progeny: Ss, Ss, Ss, Ss

Based on the assumption that spherical shape allele is dominant over wrinkle shape allele, all the F1 offspring will have spherical seeds.

<em>Hence, the probability is 1 or 100%</em>

svlad2 [7]

Answer:

1. DNA

2. Nucleus

3. mRNA

4. Transcription

5. Nucleus

6. mRNA

7. Cytoplasm

8. Ribosome

9. Translation

10. anti-codons

11. codon

12. amino acids

13. protein

Explanation:

Deoxyribonucleic acid or DNA hold all the instructions that make up an organism. It determines the physical structure and even the function of the different cells that make up all organisms.

The DNA are all stored in the NUCLEUS of cells. Typically, eukaryotic cells have a nucleus except red blood cells. The nucleus has a nuclear envelope that keeps the DNA stored inside but it has nuclear pores that allows it to interact with the cytoplasm.

In order for DNA to be replicated, it needs to be turned into messenger RNA, otherwise known as mRNA. The mRNA decodes the DNA in order for the cell to use the code. The process is called transcription.

Transcription is done within the nucleus. Before the cell can understand what to do with DNA, mRNA transcribes to know what information it needs to produce specidic proteins.

Once transcription is done, it will then bring the information out of the nucleus and into the cytoplasm. The cytoplasm is the viscous gel-like solution that holds the organelles of the cell. In the cytoplasm you have ribsomes.

Ribosomes is where protein synthesis takes place, this is why it is called the protein factory of the cell. It is a molecule that is made up of ribosomal RNA, which direct the chemical processes involved in protein synthesis. For protein synthesis to happen, it will need another type of RNA, which is the tRNA.

tRNA is transfer RNA and they translate the mRNA sequence into proteins. tRNA have amino acids attached to it.

Each 3 bases of the mRNA are collectively known as codons. These codons correspond with specific  tRNA that hold the anticodons. These anticodons code for specific amino acids that they also hold.

When they pair up, the tRNA drop off the amino acid which form a chain with the other tRNA amino acids that complete the code. These chain of monomers then make the protein specific to the DNA code that was copied in the beginning.

erastova [34]

Answer: just write "onion cell microscope slide experment" as the topic

Explanation: To study the structure of the onion epidermal cell, with particular emphasis on the nucleus and nucleoli.As the cells observed do not have a cell wall, nor a prominent vacuole, the cells of the specimen on the slide are animal cells.
