Answer:
Women need more iron than men to make up for the amount of iron they lose in their menstrual period.
Explanation:
The primary function of the chloroplasts in a plant is to convert light
from the sun into glucose and energy in a process that is known as
photosynthesis. This energy is then used by the plant cells for
incredibly important functions such as growth and repair, so the chloroplasts are amongst the most necessary parts of any plant.
Answer:
<h2>The changes that do not affect the function of a protein are called silent mutations.</h2>
Explanation:
As given here as a mutation occurs in an original DNA template that changes the DNA, by transcription this mutation passes into RNA and changes the RNA, but it does not change the protein sequence, it means that this mutation could be silent mutation.
Silent mutation is the mutation which cause the change of a base in that, after the mutation the codon codes for the same amino acid, or the amino acid which do no cause any change in the protein, hence these changes do not affect the function of a protein.
The answer is; D
This is referred to as co-evolution. It involves the reciprocal evolution of 2 species. This kind of evolution can be seen in mutualism (like the choices described above), and also predator-prey, host-parasite relationships. The term co-evolution was coined by Paul R. Ehrlich and Peter H. Raven in 1964.
Answer:
a glass of muddy water
Explanation:
Pure substances contain only one element or compound.
Calcium is one element so it is a pure substance. Ice and water have the same molecular structure, so it is a pure substance. Aluminum oxide is a chemically pure compound.
The only example that is not a pure substance is muddy water due to the multiple components of mud mixing with the components of water.
Hope that helps.
