Answer:
A substance that removes carbon dioxide gas
Explanation:
Options-
A. A substance that removes carbon dioxide gas
B. A plant to produce oxygen
C. A glucose reserve
D. A valve to release excess water
Solution -
It is given that the rate at which oxygen is consumed and the rate at which carbon dioxide is produced is same. Therefore, if we somehow are able to measure the volume of carbon dioxide, we can interpolate the rate of consumption of oxygen from it.
Hence, A substance that removes carbon dioxide gas is essential to provide accurate volumetric measurements of oxygen gas consumption
Option A is correct
Answer:
True
Explanation:
The Polymerase Chain reaction (PCR) is a technique widely used in molecular biology to identify specific DNA fragments generally in a size range of 100 to 1000 base pairs (bp). PCR sensitivity refers to the potential of the PCR technique to specifically amplify the desired sequence in the sample. PCR is a highly sensitive (and also specific) method with values around 100% if the experimental conditions are proper. However, to reach these values, it is imperative to work in optimal conditions by eliminating contaminant factors in the sample which may alter PCR amplification.

The interstitial cells in the body produce testosterone for endocrine purposes. The seminiferous tubules' generation of spermatozoa constitutes the exocrine function.
<h3>
What are Endocrine Functions of Testes?</h3>
- The pituitary and hypothalamus regulate the amount of testosterone the testes make and secrete.
- The pituitary gland receives a signal from the hypothalamus to release gonadotrophic chemicals (FSH and LH). The production of testosterone is stimulated by luteinizing hormone. The hypothalamus warns the pituitary gland to produce less LH, which instructs the testes to lower testosterone levels, if too much testosterone is being produced.
- Boys' normal physical growth need testosterone. It is the principal androgen, which is a name for any chemical that promotes and/or supports the development of the male genitalia. Many of the processes that help a boy transition to manhood during puberty require testosterone, including:
- healthy growth of male genitalia
- growth of body and face hair
- reduction in voice volume
- Adam's apple development
