Answer:
True
Explanation:
Oogenesis includes the formation of one egg cell from a single oocyte or egg mother cell. The diploid primary oocytes in the ovaries enter into the first meiotic division and form a haploid secondary oocyte and a haploid first polar body. After fertilization, the secondary oocytes complete the meiosis-II and forms one large ovum and a second polar body. The ovum formed by meiosis-II is much larger than the second polar body due to the unequal distribution of cytoplasm during meiosis-II. This imparts enough amount of cytoplasm in the zygote to support the mitosis without any cell growth.
Answer:
The correct answer will be option-E
Explanation:
The autonomic nervous system or ANS activity in the brain is mainly controlled and regulated by the hypothalamus structure. The autonomic centres of the hypothalamus control the hormonal secretion adrenal medulla like adrenaline and norepinephrine.
The secretion of the hypothalamus controls the activity of the vasomotor center which help maintain the blood pressure.
Thus, option-hypothalamus is the correct answer.
Answer:
uniformitarianism, Fossil groups, 48 million years ago.
Explanation:
- Uniformitarianism is the doctrine of uniformity that assumes that same environmental laws and process operate till date that has also occurred on the past but not with the same uniformity. Unlike the atmospheric that is short-lived and sudden changes over the period of time.
- William Smith was a geologist who has noticed a certain type of fossil in a certain layer of sedimentary and igneous rock. A similar layer of strata could be found in the areas that were further apart.
- The Permian period was from 229 to 251 million years and was the last period of the paleozoic era and is recorded for the last major extinction in the history of life in earth and it lasted for 48 million years.
The statement is True.
In Microsoft Office Excel, when the text inside a cell is longer than the width of the cell it overflows the display on the next adjacent cell on the right as long as its an empty cell. If there is a data, the other text will be hidden unless you click on Wrap text.
