Answer:
C. their gametes do not require water for fertilization to occur.
Explanation:
Seed bearing plants are plants that produce seeds. The gametes of seed-bearing plants do no depend on water for fertilization. Fertilization could occur through the transfer of pollen from the male gametophtye to the female gametophyte through animals or wind.
Unlike other plant types like the bryophytes, they rely on water for fertilization. They so have xylem and phloem as well as other plants. They also have stems,roots and leaves like other plants.
The best answer is d. endometrium.
Endometrium is the innermost layer in the Uterus, and it is found in the whole uterus.
For comparison, Cervix is the structure on the "bottom" of the uterus, vagina is below it (outside of the womb) and the ovaries if where the unfertilized eggs are.
T cells and B cells are the two main cell types that are crucial to the efforts of the adaptive immune response, in addition to cytokines and APCs.
<h3>Passive immunity is conferred by which of the following?</h3>
By supplying antibodies or lymphocytes that have already been produced by an animal or human donor, a vaccination may also impart passive protection. Most vaccines are administered parenterally (by injection), although some can also be taken orally or even nasally (in the case of flu vaccine).
Monoclonal antibodies search for and bind to the spike protein that protrudes from the coronavirus that causes COVID-19 after they have entered your body. Monoclonal antibodies that bind to the spike protein can prevent the virus from entering cells, slowing the infection.
The endothelial cell glycocalyx, which serves as a molecular sieve, and pressure gradients in the capillary beds both affect how lymph fluid is formed. toward with fluid propulsion
