Answer:
The correct answer is: Yes.
Explanation:
- Conducting research on human subjects and specimens require the research organisation to obtain prior permission or consent from the person on whose specimen the research is being conducted.
- These ethical guidelines provided by the ethical committee need to be followed by all the research organisations and scientists.
- De-identification of biological specimen refers to the non-revelation of identity and preservation of the confidentiality of the person from whom the biological specimen is derived. The person from whom the biological specimen is obtained is made anonymous.
- According to the question, Investigator A obtained the biological specimen from human subjects for conducting research on emphysema.
- Under conditions of de-identification of the specimen, the specimen can be used by the Investigator B for performing research on lung cancer without the necessity for a re-consent.
PH – depends on the environment the cell that is respiring is in.
Temperature; as it increases, the rate increases…to a point (too hot and enzymes denature!)
Answer:
C. If spiders evolved first, six legs is the derived trait.
Explanation:
A derived trait is a characteristic that is <u>present in a species but was absent in the common ancestor of this species.</u>
Spiders evolved from a crab-like ancestor and, although crabs are decapods, they possess eight walking legs and two claws. As insects evolved after spiders, the 'new' or derived trait that was absent in the ancestor would be having <u>six legs</u>.
Therefore, in this scenario, Mr. Morales states that <u>spiders evolved before insects</u>, which indicates that <u>the trait of six legs is a derived trait</u> from the last common ancestor, a characteristic that separates arachnids from insects.

Answer:Regulation: The main stimulus for ADH release is an increase in osmolality of circulating blood. Osmoreceptors located in the hypothalamus detect this increase and activate the paraventricular and supraoptic nuclei to release ADH. It also releases in response to hypovolemia
