What happens when two haploid
gametes are combined during
fertilization?
A. The cell doubles in size.
B. The diploid number is restored to the zygote.
C. The cell immediately fuses to any cell any the
vicinity
Answer:
Option B is the correct one
Explanation:
Fertilization between the haploid gametes forms a diploid zygote. ... Haploid (1n) spores germinate and undergo mitosis to produce a multicellular gametophyte (1n). Specialized cells of the gametophyte undergo mitosis to produce sperm and egg cells (1n), which combine in fertilization to make a zygote (2n)
Horses and donkeys can breed and produce sterile offspring known as mules. Horses and donkeys remain separate species because of this hybrid sterility, which is a(n) Group of answer choices post-zygotic barrier to reproduction. sympatric barrier to reproduction. pre-zygotic barrier to reproduction. allopatric barrier to reproduction. good thing.
Answer:
The correct answer is ''post-zygotic barrier to reproduction''
Explanation:
Biological barriers prevent the exchange of genes between two or more populations, a postzygotic reproductive barrier reduces the survival or reproduction of hybrid offspring. In hybrid non-viability there is low survival of the hybrid, especially during embryonic stages. On the other hand, the sterility of the hybrid occurs when the fertilized egg develops into a healthy but sterile adult. Segregation of aneuploid gametes during meiosis, different gene associations occur on the chromosomes of the parents.

What happens to waste before it is passed out of the body???
Answer:
It goes through a series of "Events" I'll talk you through them lol.
Explanation:
See, when you eat something it goes down the esophagus and into the stomach, then to your small and large intestine. While it slowly travels through your intestines, your body is slowly taking the nutrients from that piece of food, which makes the food turn into a different color, since all the nutrients is taken out of the food, then the body no longer needs that food. Then it disposes from the body!
Hope this helped!

Describe the difference in how energy is transferred to producers and consumers
Answer:
Producers create their own energy using photosyntehsis. They absorb light and water to make glucose. Consumers have to eat, they can't make their own energy.
Explanation:
If a microscope has a 40´ objective lens in place and a 15´ ocular lens, the total magnification of the microscope system under these conditions is
Answer:
600`
Explanation:
The total magnification of a microscope is obtained by multiplying the magnifying power of the ocular lens and that of the objective lens.
Mathematically.
Total magnification = ocular magnification x objective magnification
In this case, ocular magnification = 40`, objective magnification = 15`
Total magnification of the microscope system = 40 x 15
= 600`
Hence, the microscope system under these conditions would be 600`.
c) Taxol is a cancer medication that makes the structures in the cytoskeleton
more stable. This makes it harder for cells to form mitotic spindles. Why would
this be effective when fighting a tumor? (1 point)
Answer:
Explanation:
Taxol will be effective because it stops the uncontrollable cell division of cancerous cells. It makes it very difficult for cells form mitotic spindles and hence will make it very hard for the DNA to be divided. This will then stop division and causes it to die.

Which allele combination represents a female who is a carrier for an X-linked recessive disorder?
XRXr
XrXr
XRY
XrY
The allele combination XRXr represents a female who is a carrier for an X-linked recessive disorder.
X-linked recessive inheritanceFemales usually inherit two chromosomes X, while men inherit only one chromosome X (and one chromosome Y).
The inheritance of the chromosome X in females resembles mendelian inheritance because females have two X chromosomes.In this case, females having the genotype XRXr are carriers because lowercase letters denote the presence of the recessive allele.In conclusion, the allele combination XRXr represents a female who is a carrier for an X-linked recessive disorder.

A group of scientists studied the effects of exercise on insulin sensitivity in elderly women. The scientists measured the amount of insulin secreted in the saliva when given glucose. Measurements were taken at 0, 20, 40, and 70 minutes after the glucose was administered. The graph shows the data collected before and after a four-month exercise program was put into place
Which statement BEST analyzes the data shown in the graph?
A. Elderly women secrete more insulin the more they exercise.
B. Exercise decreases insulin sensitivity in elderly women.
C. Insulin sensitivity is at its highest after 50 minutes.
D. Insulin sensitivity increases as exercise decreases.
Answer:
B. Exercise decreases insulin sensitivity in elderly women.
Explanation:
I got the answer correct in a test.
Exercise decreases insulin sensitivity in elderly women.
What is Insulin?
Your muscle cells are better equipped to use any insulin that is present to take up glucose during and after exercise because their insulin sensitivity has risen.
Whether or not insulin is present, when your muscles contract during activity, your cells can absorb glucose and utilise it as fuel.
Depending on how long you exercise for, among other things, will determine how your physical activity affects your blood sugar levels.
Learn how your blood sugar changes as a result of activity. You can better understand the advantages of exercise by monitoring your blood sugar levels more frequently before and after exercise.
Therefore, Exercise decreases insulin sensitivity in elderly women.

What percentage of DNA comes from
each parent during sexual reproduction?
Answer:
50 %
Explanation:
So, each sperm contains 50% of the father's genes and each egg contains 50% of the mother's genes. This makes gametes different from other cells in the body
Answer:
50 from each parent is the correct answer

Tourniquet ____ Using your gloved hand to apply pressure on the wound to control bleeding ____ Bleeding that can be seen coming from a wound ____ The escape of blood from an artery, vein or capillary inside the body ____ A tight band placed around an arm or leg to constrict blood vessels in order to stop blood flow to a wound ____ Blood vessels that carry blood from all parts of the body to the heart ____ Vessels that transport blood to the capillaries for distribution to the cells ____ A bandage applied snugly to maintain pressure on the wound to control bleeding
Answer:
Using your gloved hand to apply pressure on the wound to control bleeding. b. Direct pressureBleeding that can be seen coming from a wound. a. External bleeding The escape of blood from an artery, vein, or capillary inside the body. d. Internal bleeding A tight band placed around an arm or leg to constrict blood vessels in order to stop blood flow to a wound. g. TourniquetBlood vessels that carry blood from all parts of the body to the heart. f. Veins Vessels that transport blood to the capillaries for distribution to the cells. e. ArteriesA bandage applied snugly to maintain pressure on the wound to control bleeding. c. Pressure bandageExplanation:
Direct pressure is a technique used to stop the bleeding on the wound. The person should place both hands over the wound and press firmly till doctors arrive. With this first aid technique, we prevent excessive blood loss, which can cause worse problems in the future.
There are two types of bleeding, external and internal. In the first one, the skin opens, and blood comes out to the exterior. In the second one, the skin is not open, so the blood does not come out to the exterior, but blood goes to tissues around the broken vessel due to an internal injury.
A tourniquet is a first-aid technique use to stop blood flow and prevent that the injured person bleeds out till death. A band, a piece of shirt, or a belt should go around the limb and tie it hard to stop the blood flow and allow the patient to arrive at the hospital. It is a technique usually use when there is a wound that affects the main vessels.
There are different types of vessels. They change in size and structure. Veins are the vessels that carry blood back to the heart, where it will go to the pulmonary circuit to be oxygenated. Arteries will take the oxygenated blood from the heart to the rest of the body. The arteries branch into small vessels called arterioles, and the arteries branch into capillaries which will give oxygen to the cells.
A pressure bandage controls bleeding and prevents the injury from being contaminated. The pressure bandage does not restrict blood flow as a tourniquet.
