ecosystem. They are sorted into three groups: producers or autotrophs,
consumers or heterotrophs, and decomposers or detritivores.</span>
Answer: Option D
Explanation:
The blood from the mother carrying oxygen, and essential nutrients is carried to the fetus.There is no different system available in the developing fetus which aids in its growth and development.
The region representing A provides oxygen and nutrients to the fetus and removes carbon dioxide from fetus.
This can be defined as an intersection between the fetus and mother so that there can be exchange of materials.
The correct term to fill in the blank would be peripheral. The two major divisions of the nervous system are the central and the peripheral nervous systems. The central nervous system consists of the spinal cord and the brain. The peripheral nervous system is made up of nerves and small amount of gray matter known as the ganglia. The nervous system is a very important part of the body as it is responsible of connecting all of the organs and the parts to the brain. It is responsible for carrying messages to the brain and out from the brain to the other parts of the body.
Answer: Peptide bond
Explanation:
Polysacharride are monomers of carbohydrates linked together by glycosidic bonds to form long chains, also proteins are polymers of amino acids linked together by peptide bonds.
Linear chains of carbohydrates are linked together by glycosidic alpha-1,4- glycosidic linkages(between the OH group of the first carbon if the 1st monomer and the OH group of the 4th carbon of the second monomer. The branched point are linked by alpha-1,6-linkages.
In proteins the alpha carboxyl group of one amino acid react with alpha amino group of another amino acid to form a peptide bond or CO-NH bridge. Proteins are made by polymerization of amino acids through peptide bonds.
Answer:
1. The bottom graph matches this statement, because it shows a drastic decrease in population.
2. The top graph matches this statement, because it shows most of the population surviving for quite some time.
3. The second graph matches this statement, because it shows a drastic increase in population.
4. This would be the third graph, because it shows a dramatic increase then a stabilization.
