Vacuoles are storage organelles that are found in both animal and plant cells. They store food or any other forms of nutrients, they also store waste products so as to protect the contamination of the cell environment. These waste products are sent out of the cell via vacuoles. In plants the vacuoles are larger than in animals. The vacuole provides plant nourishment in the scarcity of water in the external environment hence, prevents the wilting of plants.
Answer:
A new mutation
Explanation:
A mutation refers to the random changes in the DNA of organisms. A mutation changes the allele and genotype frequencies by the introduction of a new allele in the gene pool.
However, mutations are not the major factor responsible for changes in the gene pool of a population as mutations are rare. The rate of mutations is very slow and does not allow it to serve as a major factor to change the allele and genotype frequencies.
I believe it would be a fossil of a reptile but I'm not a 100% sure about it.
They are called reactants
Hey there!
Here is a paraphrased version of the text:
Objects that are nonliving never had the qualities of life, and never will. Things that are dead did have an experience to have the qualities of life, but then they eventually die, they fail to keep some of the characteristics. So in science, dead is not an identical word to nonliving. A rock is nonliving, a fallen tree is dead, and a moose is living.
Note: While paraphrasing a text, a good thing to do is to think of as many synonyms of the words in the text as you can.
Hope this helps you.
Have a great day!
