Because they are autorotrophs(they make their own food)so most organisms depend on them.
The concentration of salt in water affects the rate of osmosis because it will determine how much water should be transported or excreted or to be taken in. The cellular process is keen to the salt concentration of its system thus making sure to maintain balance between the salt concentration the right amount of water must also be in its area of release for any expected occurences.
Osmosis then is the movement of water particles from which has water and from which has not and to provide it with the sufficient H2O.

If your body lacks enzymes that break down
carbohydrates, it would be unable to get sugar molecules for energy production.
If you lacked the enzyme to digest proteins, you may not absorb enough amino
acids.
The digestive system in our body changes
carbohydrates into glucose; also known as blood sugar to be use as an important
source of energy. Meanwhile, amino acids are organic compounds that combine to
form proteins, which are the building blocks of life.
The best suited group for the mentioned plant is Angiosperms and monocot.
Answer: Option C
<u>Explanation:</u>
As mentioned the seed of the plant has one cotyledon and the specific name for these type of plants whose seeds has one cotyledon is called Monocot, Suppose if the seed of the plant has two seeds, It is called dicot.
Hence we can conclude that the mentioned plant comes under monocot and not dicot. On the other hand, Angiosperms refers to the plants that has flowers with it and gymnosperms usually includes plants without flowers and hence we can classify the plant as Angiosperm and monocot.
Answer:
The four- chambered hearts of birds and mammals are best described as <u>homoplasies.</u>
Explanation:
In evolution, homoplasies are the trait shared in different species despite that their ancestors didn't have it at all. In other words, these are traits that can be gained or lost during evolution in different lineages independently. For example, wings of birds and wings of bats do the same function (help in flying) but they were not there in the ancestors so both animals developed these structures independently.
In the given example, birds and mammals have four-chambered heart but their ancestors have 3 chamber hearts. They evolved independently and developed 4 chamber heart. This might be due to several reasons. However, their ancestors didn't have the feature so it is an example of homoplasy.
