The answer is A. <span>effective length of the tube
In wind instrument, the effective length is not the actual length of the instrument but only the length that the finger holes manage to cover.
The more holes it managed to cover, the higher frequency of vibration it might able to produce, which lead to higher pitch of the instrument.</span>
The answer is that they are somatic cells
Answer:
The correct answer will be option-C.
Explanation:
Hypothalamus is a part of the brain which controls many important functions of the body by producing hormones.
When the amount of water gets reduced in the blood, it leads to a change in the osmolarity which can be easily detected by the osmorecpetors present in the neurons of the hypothalamus.
In response, neurons secrete Anti-diuretic hormone in the blood which acts in the tubules of the kidney where they help in re-absorption of the water from the body.
Thus, Option-C is the correct answer.
The current population of a threatened animal species is 1.6 million, but it is declining with a half-life of 25 years. How many animals will be left in 35 years<u> The decay law i</u>
<u>p(t) = 1,700,000 (1/2)t/25</u>
<u>where t is in years and p(t) is the population at time t. Plug in 40 and 55 for t.</u>
<h3>What is
threatened animal?</h3>
Any species (including those of animals, plants, and fungi) that is likely to become endangered in the near future is considered to be a threatened species. The population dynamics measure of critical depensation, a calculation of biomass related to population growth rate, is occasionally used to identify threatened species. This quantitative indicator is one way to gauge how endangered an area is. When discussing IUCN categories, the terms threatened and vulnerable may be used interchangeably; however, threatened generally refers to the three categories (critically endangered, endangered, and vulnerable), whereas vulnerable generally refers to the category that is least at risk among the three. However, since all threatened species are vulnerable species, they can usually be used interchangeably.
