Answer:
D. four haploid cells
Explanation:
When meiosis is complete,four haploid cells are formed from a single diploid cell. The four daughter cells produced that contains half the number of chromosome than that of their parent cell. Due to meiosis the number of chromosomes remain fixed in a species from generation to generation.
The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell. Meiosis has both similarities to and differences from mitosis, which is a cell division process in which a parent cell produces two identical daughter cells.

Embryonic stem cells are undifferentiated cells. They can grow and divide giving rise to any type of tissue in a developing embryo. What must be true of the DNA in an organism's stem cells?
Answer:
Stem cells cut and repair their own DNA to promote formation of new tissues.
Explanation:
Stem cells cut itself and then repair their own DNA as a mechanism of activating genes that promote the development of new tissues. Stem cells are special type of cells that the ability to develop into many different types of cell such as muscle cells, brain cells etc. These cells are also capable to repair damaged tissues in the body.

This condition is present from birth. It can occur with other heart defects. The heart's ventricles are the two lower chambers of the heart.
location :
Bicuspid valve is one of the four valves of the heart which is situated between the left atrium and the left ventricle. Tricuspid valve is one of the four valves of the heart which is situated between the right atrium and the right ventricle. Bicuspid valve is present in between the left atrium and the left ventricle.

What is structure of eye?Three coats enclose the optically clear aqueous humour, lens, and vitreous body in the eye.
The cornea and sclera form the outermost coat; the choroid, ciliary body, and iris form the middle coat, which contains the main blood supply to the eye and extends from the back to the front.
The eye functions as a sensory organ. It collects light from our surroundings and converts it into nerve impulses. The optic nerve sends these signals to the brain, which creates an image and thus provides sight.
Thus, as per the labeling number, Vitreous gel, Optic Nerve, Macula, Fovea, Retina, Lens, Pupil, Cornea, Iris respectively are the parts of eye.

true or false? Embryonic stem cells are more limited in what they can become than somatic stem cells
Answer:
true
Explanation:
Embryonic stem cells.
These are pluripotent (ploo-RIP-uh-tunt) stem cells, meaning they can divide into more stem cells or can become any type of cell in the body. This versatility allows embryonic stem cells to be used to regenerate or repair diseased tissue and organs.

Which of the following solar phenomena is thought to cause short term climate changes?
A) solar flares
B) prominences
C) sunspots
D) solar winds
Answer:
Solar flares
Explanation:
The magnetic field lines near sunspots often tangle, cross, and reorganize. This can cause a sudden explosion of energy called a solar flare. Solar flares release a lot of radiation into space. If a solar flare is very intense, the radiation it releases can interfere with our radio communications here on Earth.
