Answer:
SAM and HPA
Explanation:
The physiology of stress has two components. One in which is a fast response meditated by the SAM axis, and one which is a slow response meditated by the HPA axis.
Answer:
See the steps below (8,681.25 g of will be needed0
Explanation:
From the equation, 4 moles of H2 requires 1 mole of Fe3O4.
1st step: calculate the number of mole of 300 g of H2.
mole = mass/molar mass
Mole of 300 g H2 = 300/2 = 150 mole
Hence, 150 moles of H2 will require: 150/4 = 37.5 moles of Fe3O4.
Step 2: Use the mole of Fe3O4 to calculate the mass of Fe3O4
mass = mole x molar mass
mass of 37.5 mole Fe3O4 = 37.5 x 231.5 = 8,681.25 g
Hence, 8,681.25 g of Fe3O4 will be required to completely react with 300 g H2
<h3><u>Answer;</u></h3>
<em>Common ancestry </em>
Similar DNA sequences in genes can be evidence of <u><em>common ancestry</em></u>
<h3><u>Explanation;</u></h3>
- <em><u>DNA molecules are fundamental molecules in organisms since they carry genetic information in living organisms.</u></em> DNA sequences similarity among various organisms may be used to establish evolutionary relationship among living organisms.
- <em><u>Many organisms have distinct DNA sequences, however, animals may share some specific types of genes which are similar genetically in the sequences of DNA. </u></em> Organisms or animals whose DNA sequences are similar share common evolutionary origin.
