Answer:
Low levels of dissolved oxygen would decrease the diversity of the fish population.
Explanation:
Salinity means an increase of the dissolved salt content in a water body.Water that has a high content of salt contains low amount of dissolved oxygen and therefore, it becomes a less appropriate environment for some aquatic organisms.
Although, most of the water bodies have specific optimal salinity range, They can adjust to live in that certain range, however, if salinity increases beyond that range , water bodies will shift from that environment to a new one that is more suitable for them to live. On the other hand, fish or other waterbodies that are more tolerant to salinity will migrate to this acquatic zone and will adapt there. But sometimes, an abrupt increase in salinity do not give alot of time to the fishes to relocate and they just die from salt stress. This has something to do with decreasing the diversity of fish population.
Hope it help!
Answer:
The correct answer is C: "The secretory phase of the uterine (menstrual) cycle occurs when <em>progesterone stimulates the endometrium to prepare it for implantation".</em>
Explanation:
The luteal phase, also known as a <u>secretory phase </u>or postovulatory phase, has place immediately <em>after ovulation</em>, from 15th to 28th day, and it lasts <em>until the end of the menstrual cycle</em> when bleeding starts again.
During the secretory phase, the <em>follicle</em> in the ovary <em>produces </em><em>progesterone</em> to keep <em>preparing the uterus for a possible pregnancy</em>. If there is no fecundation, estrogen and progesterone levels fall as the follicle reduces. When this happens, the endometrial is eliminated as menstruation and a new cycle begins.
<em>If the ovule is fecundated, </em><em>it occurs implantation</em><em> </em>and follicles continue to produce progesterone and estrogen in high amounts to sustain the endometrial until the placenta is formed.
Answer:
Cytokinesis occurs in mitosis and meiosis for both plant and animal cells. The ultimate objective is to divide the parent cell into daughtercells. In plants , this occurs when acell wall forms in between the daughter cells. In animals , this occurs when a cleavage furrow forms.
The answer would be true! A table does display data in a row and columns!
