D :) try it at home or go to the forest and you will see tiny brown dots
<span>on the underside of some fern fronds - called sori. these contain big amount of spores.</span>
Answer: d. insulin
<span>Actually, there are two hormones secreted by islet cells within the pancreas: insulin and the glucagon. However, their secretions in response to blood sugar levels, are in opposite fashion! </span>
<span>Insulin is normally secreted by the beta cells of the pancreas while glucagon by the alpha cells. The </span><span>amount of insulin secreted into the blood increases as the blood glucose rises. In the same way, as the blood glucose falls, the amount of insulin secreted by the pancreas goes down.</span>
In glucagon, it is opposite. If blood glucose is high, then there is no glucagon secreted. Therefore, the answer is insulin.
Changes to an organism that are a results of or results in genetic mutation alter the genetic makeup of an organism and can be passed on to the next generation.
Answer:
Biodiversity will increase which will make the ecosystem more immune towards diseases and changes in weather.
Explanation:
Example: If u have 1 type of fish in a lake and suddenly the water became salty for some reason, that kind of fish may not survive and if it doesn't there will be no life left in the lake, but if there were multiple types of fish and other animals then some of them would be able to survive and adapt on the change in environment. Hope I helped!
there are two or three types or methods in which they change according to the class you study so this a answer from a 8th grader ( there are difference in classes)
<u>Nitriates</u> are a form of <u>nitrogen</u> that is usable by plants.
It is assimilated into plant tissue as protein. The nitrogen is passed through the food chain by animals that consume the plants, and then released into the soil by decomposer bacteria when they die.
Nitrification is the conversion of ammonia (NH3) to nitrate (NO3). It is usually performed by soil living bacteria, such as nitrobacter. This is important because plants can assimilate nitrate into their tissues, and they rely on bacteria to convert it from ammonia to a usable form.
denitrifying bacteria convert nitrogen into ammonia which is a form of nitrogen that is useful to humans. Bacteria "fixes" gaseous nitrogen into nitrogen usable by plants in the form of nitrate.
