Organisms that digest molecules in organic material and convert them into inorganic forms are called decomposers. They are classified as heterotrophic since they use organic substances in obtaining the energy and nutrients they need to survive. They are organisms that are responsible for breaking down decaying organisms into simple molecules in order to bring these back to the biogeochemical cycles into the ecosystem. In the food chain, they are the last step. Examples of these decomposers are fungi, snails and some insects. These organisms do not have an internal digestive organs since the the organic substrates undergo biochemical reactions only.
The cell’s DNA is first transcribed in a temporary copy (mRNA), which is then translated into the amino acid sequence of protein.
The combination of weathering and movement of the resulting sediments is called erosion. Lithification is the changing of sediments into rock. There are two processes involved in this change, compaction and cementation.
Answer:
Option D, The chance that you share an allele with either a parent or a sibling is one half.
Explanation:
All individuals receive 50 percent of their genes from each parent, Thus, it can be said that each sibling will share nearly half of their genetic material with each parent. In case of full siblings (when both the parents are same), 50 percent of their genetic material matches.
For instance,
There are two parents each with genotype AA and aa
Cross between AA and aa will produce following offspring
AA * aa
Aa, Aa, Aa, Aa
Thus, each offspring will have one gene from each parent and hence they share 50% of their genetic material with their parents
Two siblings get the same gene from their two parents. Hence, 50 percent of their genetic material matches.
Hence, option D is correct
Answer:
Hemoglobin
Explanation:
Hemoglobin is the protein present in the red blood cells of the blood. The protein hemoglobin serves as oxygen carrier and binds to the oxygen in lungs. As blood flows from lungs to the different body parts, hemoglobin serves to carry oxygen from lungs to various cells of the body. At higher partial pressure of carbon dioxide and lower pH of cells of the body, the hemoglobin releases oxygen and thereby, serves as oxygen carrier.
