An acentric fragment is one result of crossing-over between a normal chromosome and a chromosome that has undergone what kind of mutation?
Answer:
paracentric inversion
Explanation:
A paracentric inversion happens as a result of a portion of one chromosome , or a packet of genetic information, which is flipped such that there are changes in the order of genetic information. Every of the chromosome has a part that is near the middle which is referred to as a centromere. Paracentric inversions do not include the involvement of the centromere of a chromosome.

Gas exchange involves the transport of two respiratory gases, oxygen and carbon dioxide. Review how each gas is transported between the atmosphere and the cells of your body by completing this exercise.1. required for cellular respiration
2. net diffusion from alveoli to lung capillaries3. sometimes transported as bicarbonate
4. net diffusion from body tissues to blood
5. net diffusion from lung capillaries to alveoli
6. waste product of cellular respiration7. enters alveoli during inhalation
8. transported by hemoglobinA. Oxygen onlyB. Carbon Dioxide OnlyC. Both Oxygen and carbon dioxide
Answer:
When we breathe, we inhale oxygen and we exhale carbon dioxide.
Explanation:
1. For the cellular respiration, the body cells are provided with oxygen during gas exchange in respiration.
2. Oxygen gas diffuses from alveoli to the capillaries in our lungs.
3. Carbon dioxide is always transported in plasma or bounded to the hemoglobin or in some form of bicarbonate.
4. Carbon dioxide gas diffuses from our body tissues to the blood.
5. In our lungs, carbon dioxide gas diffuses from capillaries in to alveoli. Carbon dioxide leaves the body when we exhale.
6. During cellular respiration, we give give out and removes carbon dioxide from our body which is a waste product.
7. When we inhale, both oxygen and carbon dioxide gases enters the alveoli,
8. All the oxygen present in blood is bounded by hemoglobin and it is carried to all the body tissues and body and diffuses from our blood to our body tissues.

Two factors that affect human sleep patterns are the time of day and level of melatonin, a chemical found in one's body. For example, as the Sun goes down at night, the body knows it is time to go to sleep. Similarly, when a person's level of melatonin changes, they can become alert or sleepy. Using this information, how could these stimuli be described?
A. Hours of sunlight per day and melatonin levels are both Internal stimuli.
B. Hours of sunlight per day and melatonin levels are both external stimull.
C. Hours of sunlight per day is an external stimulus, while the level of melatonin in a person is an internal stimulus.
D. Hours of sunlight per day is an internal stimulus, while the level of melatonin in a person is an external stimulus.
E. Hours of sunlight per day and melatonin levels are both internal and external stimuli.
Answer:
C. Hours of sunlight per day is an external stimulus, while the level of melatonin in a person is an internal stimulus.
Explanation:
Melatonin is a hormone therefore internal. Sunlight is outside of the body therefore external

What happens when a cell reaches the Hayflick limit ? Why does this have to happen for the health of the cell?
Answer:
The Hay-flick Limit is a concept that helps to explain the mechanisms behind cellular aging. The concept states that a normal human cell can only replicate and divide forty to sixty times before it cannot divide anymore, and will break down by programmed cell death or apoptosis.

Why are surface antigens on sperm cells not recognized as “self,” and why do they require a blood-testis barrier to prevent antibody formation?
Answer: Sperm cells are recognised as foreign cells by the immune system and requires blood testis barrier to prevent antibody formation.
Explanation:
Shortly after birth, the immune system of an individual starts to recognize the surface antigens of its body cells as 'self' and avoids forming an antibody against it. Spermatozoa (sperm cells) are formed at puberty, between the age of 10 and 14. Hence, the body immune system will recognise the antigen on the sperm cells as 'non-self' and stimulate antibodies against it. This is prevented by the blood testis barrier.
The blood testis barrier which are formed from the Sertoli cells at the seminiferous tubules helps in the isolation of the sperm cells and protects it from immune surveillance. This barrier also prevents sperm cells from coming in contact with blood.
Sperm cells formed during puberty hence immune system recognize them as non-self. Immune attack is prevented by the blood-testis barrier.
Blood-testis barrier:
It is the barrier that is made from the Sertoli cells in the seminiferous tubule. This helps to isolate the sperm cells from the immune surveillance. This also protects sperm cells to come in contact with blood.
Sperm cells formed during puberty hence immune system recognize them as 'non-self'.
Therefore, Sperm cells formed during puberty hence immune system recognize them as non-self. Immune attack is prevented by the blood-testis barrier.
