Seems pretty tough
Good luck with it
Phytoplankton; small cells that use photosynthesis to turn sunlight into food that live near the surface of the ocean. There also responsible for about half of the Earth's primary production. The seasons also affect how well there doing, they need the climate best for them to produce right, changing seasons doesn't nearly affect them as much as climate change though.
Hope this helps, have a BLESSED day! :-)
Answer - 1,000 kcal/day
Given the situation above, Matthew should consume an extra <span>1,000 kcal per day in order </span>to regain to a healthy weight. This <span>will promote a two pound weight gain </span>per week. <span>Typically, one pound of fat weighs 3500 kcal, so it would takes </span>an extra<span> 3500 </span>calories<span> to gain one pound of body weight.</span>
Answer:
pre-zygotic reproductive isolation
Explanation:
<em>The molecules regulate the pre-zygotic reproductive isolation mechanism.</em>
<u>Reproductive isolation generally refers to the variety of biological processes that sustain the formation of new species of biological organisms. </u>
Some of these processes <em>act to prevent fertilization or the formation of zygotes between organisms that are not of the same species</em> (pre-zygotic mechanisms) while others <em>ensure that the product of fertilization is invalid</em> in case the former fails (post-zygotic mechanisms).
Some pre-zygotic mechanisms ensure that there exists no form of mating among organisms that are not of the same species due to incompatible reproductive organs, but where this fails, another pre-zygotic mechanism will act so that that the mating will not lead to fertilization and there will not be formation of zygotes.
The prevention of fertilization between organisms with compatible reproductive organs but of different species is carried out by molecules. These molecules ensure that there are locks and keys in place to prevent the fertilization of the egg by the sperm.
lesser
Explanation:
Reykjavik the capital city of Iceland heats its buildings using geothermal energy sources at a cost that is lesser of what it would be if oil were used.
In all ramification, the use of geothermal energy sources is far more preferable and better than using fossil fuels like oil.
- Geothermal energy is energy from within the earth
- It is natural and renewable source of energy.
- The cost of product is very low
- It has little to no impact on the environment as well.
- They are usually found where magma pockets are close to the surface
