Are there any parts of the human body that get oxygen directly from the air and not from the blood? Are there nuclear reactions going on in our bodies?
Answer:
The cornea is the only part of a human body that has no blood supply; it gets oxygen directly through the air. The cornea is the fastest healing tissue in the human body, thus, most corneal abrasions will heal within 24-36 hours.
Nuclear reactions do indeed occur in the human body, but the body does not use them.

of the circulation process?
• A. The blood releases carbon dioxide on the way back to the heart.
•
B. The blood goes through the liver to be cleaned.
O C. The blood travels back to the heart in a vein.

Flatworms are free-living or parasitic animals, with bilateral symmetry, triblastic and with no coelom. The correct answer is FLATWORMS.
What are the flatworms?These are animals of variable size, going from a few millimeters to centimeters.
Flatworms are bilateral, acoelomated, and triblastic animals. The fact of being acoelomate means that they lack an internal cavity. Their whole body is solid, having mesenchyme where different organs are located.
Sense organs are located in the anterior part of the body.
These animals are hermaphrodites, exhibiting cross reproduction and eventually autofecundation.
They might be free-living animals or parasitic.

Hysterectomy Is a surgical removal ofthe Uterus.It may or may not be accompanied by Salpingo-oophorectomy, removal of the uterine tubes and ovaries. Why would it be an advantage to leave the ovaries intact
It is an advantage to leave the ovaries intact because the woman will still be able to produce eggs and children through In vitro fertilization.
What is an Ovary?This is a part of the female reproductive system which serves as the site for egg production.
When the ovaries are intact, the eggs can be taken and fertilized with the sperm in a lab dish and implanted into the uterus of another female for development of the zygote.

What happens to energy from the Sun when it reaches Earth
Answer:
The energy from the sun that reaches Earth’s surface is mostly “shortwave” radiation – mostly visible light. This energy passes freely through the atmosphere and is absorbed by Earth’s surface. The surface warms from the energy input, and some of its heat projects back to the atmosphere as infrared radiation.
Explanation:
Energy released from the Sun is emitted as shortwave light and ultraviolet energy. When it reaches the Earth, some is reflected back to space by clouds, some is absorbed by the atmosphere, and some is absorbed at the Earth’s surface. … Shortwave radiation reflected back to space by clouds.

Each embryo has some type of tail bone, whether it may or may not be used when actually born.
This can be used to support evoultion because the similarities clearly and visibily show a common ancestor between embryos. Because of their obvious similar traits, embryos must share ancestral DNA that they evolved from.

15. If out of 100 offspring, 74 are purple flowered and 26 are white, what were the likely genotypes and
phenotypes of the parents if this is a simple monohybrid cross?
Answer:
so it would be a 3 : 1 ratio.
Explanation:
The probable genotypes of the parents is Pp (Purple). When we will cross the two heterozygous purple flowers we will get the purple and white coloured flowers
The ratio would be 3:1. The parents' likely genotypes are Pp (Purple). Purple and white colored flowers will result by crossing two heterozygous purple blooms.
What are Genotypes and Phenotypes?The type of variant existing at a specific locus (i.e., region) in the genome is scored by what is known as a genotype. Symbols can be used to symbolise it. For illustration, BB, Bb, and bb might be employed to denote a certain gene variant.
The term "phenotype" refers to an organism's observable qualities, which are a multifactorial result of hereditary attributes and environmental factors. The physical, biochemical, physiological, and behavioral characteristics of an organism make up its phenotype.
Pp is the likely genotype of the parents (Purple). In the example presented above, combining two heterozygous purple blossoms will produce flowers that are both purple and white.
Thus, the ratio would be 3:1. The parents' likely genotypes are Pp (Purple). Purple and white colored flowers will result by crossing two heterozygous purple blooms.
