Asexual reproduction produces offspring that are genetically identical to the parent because the offspring are all clones of the original parent. This type of reproduction occurs in prokaryotic microorganisms (bacteria) and in some eukaryotic single-celled and multi-celled organisms.
Which process produces only genetically identical offspring?
Asexual reproduction produces offspring that are genetically identical to the parent because the offspring are all clones of the original parent. This type of reproduction occurs in prokaryotic microorganisms (bacteria) and in some eukaryotic single-celled and multi-celled organisms.
Which structure produces chemicals that regulate the reproductive system?
These are chemicals that stimulate or regulate the activity of your cells or organs. The primary hormones involved in the functioning of the male reproductive system are follicle-stimulating hormone (FSH), luteinizing hormone (LH) and testosterone. FSH and LH are produced by the pituitary gland .
Which structure produces cells that have potential to become gametes?
Early in the development of the embryo, specialized diploid cells, called germ cells, are produced within the gonads, such as the testes and ovaries . Germ cells are capable of mitosis to perpetuate the cell line and meiosis to produce gametes.
Which statement best explains how each of the different cell types can develop from the same embryo?
Which statement best explains how each of the different cell types can develop from the same embryo? The cells have identical genetic instructions, but different parts of these instructions are being expressed in each cell.
Are the parents and the offspring identical?
In sexual reproduction one full set of the genes come from each parent. Living things produce offspring of the same species, but in many cases offspring are not identical with each other or with their parents. ... Changes in genes can be caused by environmental conditions, such as radiation and chemicals.
Can humans reproduce asexually?
Humans cannot reproduce with just one parent; humans can only reproduce sexually. ... These organisms can reproduce asexually , meaning the offspring (“children”) have a single parent and share the exact same genetic material as the parent. This is very different from reproduction in humans.
Where does the absorption of ATP occur?
Chloroplasts , the sites of photosynthesis, are surrounded by an inner and outer membrane; a complex system of thylakoid membranes in their interior contains the pigments and enzymes that absorb light and produce ATP.
Why are ovaries known as the female gonads?
Ovaries are the female gonads — the primary female reproductive organs. These glands have three important functions: they secrete hormones , they protect the eggs a female is born with and they release eggs for possible fertilization.
How will you make your reproductive system healthy?
- Quit smoking. A single stick of cigarette contains countless toxic compositions that lead to addiction, cancer and coronary issues. ...
- Go for regular screenings. ...
- Practice safe sex. ...
- Have regular orgasms. ...
- Increase consumption of calcium and magnesium. ...
- Final note.
Which life function is not necessary for an individual organism stay alive?
The life process that is not necessary for the life of a single organism is reproduction 20. Control and coordination of life activities is carried on by the regulation system.
In which structure S would sperm cells normally be deposited?
The male gonads, or testes, produce sperm within the seminiferous tubules ; the sperm are housed here until they are nearly mature, at which point they enter the epidydimis for full maturation. The testes are housed in the scrotum, an external sac that keeps the sperm at a temperature lower than that of the body.
Which structure provides the optimum temperature for sperm production?
The two oval-shaped testes (also called testicles) lie outside the body in a pouch of skin called the scrotum, where they can maintain the optimum temperature for sperm production – approximately 5° F, lower than body temperature.
Which statement best explains the fact that some identical twins?
Which statement best explains the fact that some identical twins appear different from one another? Their DNA is essentially the same and the environment plays a significant role in the expression of their genes.
What best describes how different cell types develop?
Which of these statements best describes how different cell types develop? Each cell type contains only the active parts of the DNA needed for that cell type . ... Each cell has multiple copies of DNA that are affected in different ways by the environment to change the function of the cell at regular intervals.
Which structure does the placenta normally develop?
The placenta is a structure that develops in the uterus during pregnancy. In most pregnancies, the placenta is located at the top or side of the uterus. In placenta previa, the placenta is located low in the uterus.
