In photosynthesis, water, carbon dioxide
Answer:
3) Fertilization membrane.
Explanation:
When sperm cell fertilizes an egg cell, signal transdution occurs which causes fertilization membrane to be formed. Ovum thickens and hardens the vetelline membrane causing separation and prevents multiple fertilization by the spermatozoon.
Answer:
E. 3, 6, 7, 4, 5, 8, 1, 2
Explanation:
Systemic circulation is the circulatory pathway which is involved in the transport of the oxygenated blood to the body when pumped by the heart through arteries, capillaries and then back to the heart.
In the given question, the order of vessels in the systemic circulation has been asked which begins with the entry of the deoxygenated blood to the heart.
1. The deoxygenated blood enters the blood from vena cava to the right ventricle.
2. From the right ventricle, the blood enters the right atrium which pumps the de-oxygenated blood to the lungs through an artery called the pulmonary artery.
3. In the lungs, the blood becomes oxygen rich and is returned to the left atrium through the pulmonary vein.
4. The blood then enters the left atrium which is then pumped to the body through the main artery called the aorta.
This completes the systemic circulation and thus, Option-E is correct.
Phagocytic response is considered the most effective host defenses in combating S. aureus infection.
<h3>What is phagocytic response?</h3>
Phagocytosis is a type of cell response that plays a key role in the course of an immune response as well as in the remodeling of tissues and the healing of wounds. Professional phagocytes are specialized cells that can carry out this task quite effectively.
<h3>What is S. aureus infection?</h3>
It has long been known that S. aureus is one of the most significant germs that harm humans. It is the main contributor to skin and soft tissue infections such cellulitis, furuncles, and abscesses (boils). Boils are the most typical staph infection form. This is a pus-filled pocket that forms in an oil gland or hair follicle. Typically, the skin around the infected area turns red and swells. To treat staph infections, doctors frequently administer cefazolin, nafcillin, oxacillin, vancomycin, daptomycin, and linezolid. Vancomycin may be necessary for staph infections that are severe. This is due to the fact that a large number of staph bacterium strains have developed resistance to other common antibiotics.
Thus from above conclusion we can say that phagocytic response is considered the most effective host defenses in combating S. aureus infection.

Answer:
b. What is the difference between dominant and recessive traits? Dominant traits are always expressed when the connected allele is dominant, even if only one copy of the dominant trait exists. Recessive traits are expressed only if both the connected alleles are recessive.
c. In the simplest possible terms, purebreds are the offspring that result from mating between genetically similar parents while hybrids are the offspring that are the result of mating between two genetically dissimilar parents.
