Answer:
1200m
Explanation:
Let the depth of sea be x.
Given that the sound has to travel to the bottom of the sea and get reflected back to the ship itself, thus total distance traveled by the sound is 2x.
Time taken to hear an echo t=1.6 s
Therefore, 2x = vt
Hence, we have 2x =1500m/s × 1.6s
=> 2x = 2400
⟹ x = 2400 ÷ 2
= 1200m
Hence, the final answer is 1200m
Zygote, and it is diploid (2n) because it has 46 chromosomes
<u>Answer:</u> C. A plant absorbing carbon dioxide during photosynthesis
<em>A plant absorbing carbon dioxide during photosynthesis can be considered as assimilation in the carbon cycle.
</em>
<u>Explanation:</u>
<em>The process of carbon fixation is called assimilation in carbon cycle. In the atmosphere carbon occurs in the form of carbon dioxide. </em>
By the process of carbon fixation this carbon dioxide is converted into carbon compounds and these act as source of energy in an ecosystem.
Photosynthesis is an example of carbon fixation process. Other processes like chemo-synthesis also fix carbon. <em>Majority of carbon fixation takes place in marine environments. </em>
answer:
During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses. The chromatin coils and becomes increasingly compact, resulting in the formation of visible chromosomes. ... The replicated chromosomes have an X shape and are called sister chromatids
