Answer:
<u>In the scientific method, theories offer explanations for facts.</u>
Explanation:
Scientific theory is based on complex observation, inference and experimentation techniques. Usually, the resulting reports are checked and peer-reviewed thoroughly before being accepted as explanations for facts evidence.
Thus, theories are rigorously tested, and verifiable explanations for facts which are based on observations.
False
Coccidioides immitis is not a member of domain bacteria.
Coccidioides immitis is a dimorphic fungus that causes the fungal disease; coccidioidomycosis. Coccidioides immitis is mainly found in soils and it exists in two different forms (saprophytic and parasitic). When Coccidioides immitis enter a host, their spores separates from the hyphae and develop into round structures (spherules) that divides to form endospores which causes infection within the host.
Answer:
Explanation:
The above mentioned key points are mechanisms by which cells used to correct replication error and repair damaged DNA.
Proof Reading: while printing a page, the typesetter set the types and impression is taken, proof reading is done to correct mistakes if any, and the final printing is done. A similar follow up mechanism is done after DNA synthesis. If DNA polymerase detects an incorrect nucleotide pair, it will remove and replace with the correct nucleotide immediately.
Mismatch Repair:even after DNA synthesis, mismatch area(insertion or deletion) can be identified on the newly synthesized DNA.
In the mismatch repair, specific proteins scan the newly synthesized DNA strand. The mismatch area is identified and loop.
The second protein complex remove the mismatch segment. Finally correct segment is synthesized by the help of DNA polymerase, SSBs and ligase.
DNA damage repair mechanism: when DNA get damaged, there's a repair process that fix the damage. This includes Direct reversal, excision repair and Double stranded break repair
The right answer is Calcium
99% of the calcium is located in the bone, ensuring the skeletal strength and the hardness of the teeth.
In children and adolescents, it promotes bone growth; in young adults, it participates in the maintenance of bone capital; in the elderly, it contributes to the prevention of osteoporosis.
Beside the bone, calcium has other functions like blood coagulation, muscle contraction, nerve conduction, activation of certain enzymes.
Adequate calcium intake - consistent with the recommended dietary intakes - would have a preventive effect against high blood pressure.
