Which of the following do all cells in a multicellular organism have in common?1. They all express the same genes.

2. They all have the same proteins.

3. They all have the same mRNA.

4. They all have the same DNA.

Answers

Answer 1
Answer:

The correct answer is (d) They all have the same DNA.

  • All the multicellular organisms have same DNA but the different parts of the body has different gene expression.
  • For example: the same DNA is found in the cells of kidney and liver, but the gene expression for liver results in large number of hepatocytes and the same DNA in the kidney will give rise to nephrons.
  • This proves that all the cells in the multicellular organisms have same DNA but their expression of protein in different cells are different.

On the other hand, an unsustainable society would have an emphasis on using fossil fuels due to being cheaper and having an ever-increasing productions of goods, not considering how taxing this might be on the planet. 

Mitosis results in the formation of how many cells; meiosis results in the formation of how many cells? see concept 13.3 (page 262)

Answers

Mitosis results in the formation of two diploid cells while Meiosis results to the formation of four haploid cells. Mitosis is a process that takes place in the somatic cells; a cell that has doubled its genetic material divides to produce two diploid daughter cells while meiosis is a process that take place in the gamete cells where a doubled cell undergoes two rounds of division producing four haploid cells. 

which of the following hormones has a different effect when it is released in males instead of females?

Answers

Answer;

Follicle- stimulating hormone (FSH)

Explanation;

-Follicle stimulating hormone is produced by the pituitary gland. It regulates the functions of both the ovaries and testes. Lack or insufficiency of it can cause infertility or sub-fertility both in men and women.

-Follicle stimulating hormone is one of the hormones essential to pubertal development and the function of women’s ovaries and men’s testes.

-In women, this hormone stimulates the growth of ovarian follicles in the ovary before the release of an egg from one follicle at ovulation. It also increases oestradiol production. In men, follicle stimulating hormone acts on the Sertoli cells of the testes to stimulate sperm production.
Human sex characteristics and biological-oriented behaviors are sometimes the cause of the hormonal release inside the gland organs in the human body. For instance, in males testosterone is the hormone or gland which is responsible for the many functions of the male sex characteristics.
