Answer:
(4) tissues
Explanation:
There are three circles the innermost circle indicated the cells middle circle is the tissues and the outermost circle indicated the organs. Multicellular organisms are made up of thousands of different types of cells .Different cells constitute together forma a tissues and different tissues form a organ and different organs together form an organ system. Hence the X labeled circle denotes the tissues.
The answer is archaea. Though <span>bacteria, protozoa, </span>unicellular<span> algae, and </span>unicellular<span> fungi are all unicellular, archaea are the only ones that can survive in harsh environments</span><span />
Answer:
The higher the altitude the lower the air pressure and therefore the lower the oxygen levels. Low oxygen means low oxygen is getting to the lungs and into the blood and into tissues. Therefore Krebs cycle becomes ineffective in generating ATPs, the energy currency of cells. Mountain climbing is a physically extraneous exercise hence energy is required by the body yet the cells are no producing enough ATPs.
This effect is similar to cyanide permanently binding to Cytochrome c oxidase that catalyzes the reduction of oxygen as the ultimate electron and proton acceptor in the Krebs cycle. Oxygen reduction is significant in the generation of ATPs in the mitochondria.

Answer: Recessive Gene. Homo zygote Allele.
Explanation:
Each gene is composed of two alleles. Alleles can be Dominant or Recessive. A Dominant gene is always expressed on the Phenotype (XX/Xx); A Recessive gene expresses on the Phenotype if both alleles are the same (xx).
In this statement, it's implied that the gene that codes for "blue-eyes" is recessive, since both parents had to provide the same allele for it to express.
