Answer:
<em>The correct option is A) Reproductive assurance: any individual of the same species is a potential mate.</em>
Explanation:
A hermaphrodite can be described as an organism that is capable to produce gametes associated with both the male and female sexes. It has a complete or partial reproductive organ.
In the deep sea, biodiversity is scarce. There are limited amounts of organisms present. Hence, to have a reproductive assurance, the organisms present in the deep sea are mostly hermaphrodite. Hence, they will be able to mate with any organism of the same species.
(Initial individuals + newborn individuals) - dead individuals = total individuals
Growth rate = (total individuals/initial individuals) * 100
Population growth rate = new percentage minus 100%
Calculations
(1000 + 500) - 200 = 1500 - 200 = 1300
Growth rate = (1300/ 1000) * 100
= 1.3 * 100
= 130%
Population growth rate = 130% - 100%
= 30% per year if it is uniform
Answer:
They have helical thickening of lignin in their walls to prevent collapse
Explanation:
the primary function of Xylem and its conducting vessels tracheids is to provide support and tranport water and minerals in plants.
Xylem vessels have layers of dead materials in the walls called LIGNIN. Lignin is a polymer; a very strong, hard materials that stop water passage through it,because it contains dead cells,
Therefore the presence of deposit of these strong impermeable, ligified walls in its walls prevent its collapse during mass flow of water of transpiration pull.
Organelles exist within cells, which exist within tissues. Communities exist within ecosystems, which exist in the biosphere.
Answer:
Epididymis
Explanation:
From the testes, the sperms travel to the epididymis. These structures can be found resting on top of each testes. Fresh out of the testes, sperms are not yet matured and this is where the epididymis takes over. The sperm are stored here and this is where sperm matures. From here, the sperm moves into the vas deferens.
