Nonpolar: tail; hydrophilic
Answer;
Follicle- stimulating hormone (FSH)
Explanation;
-Follicle stimulating hormone is produced by the pituitary gland. It regulates the functions of both the ovaries and testes. Lack or insufficiency of it can cause infertility or sub-fertility both in men and women.
-Follicle stimulating hormone is one of the hormones essential to pubertal development and the function of women’s ovaries and men’s testes.
-In women, this hormone stimulates the growth of ovarian follicles in the ovary before the release of an egg from one follicle at ovulation. It also increases oestradiol production. In men, follicle stimulating hormone acts on the Sertoli cells of the testes to stimulate sperm production.
b. gel electrophoresis.
c. an electrical current.
d. whole animal cloning.
The answer is A .
PCR stands for Polymerase Chain Reaction. It is a method to analyze a short sequence of DNA or RNA and is used to reproduce (amplify) selected sections of the nucleic acid. Untold numbers of copies can be made of the DNA in just a few hours.
PCR amplifies the regions of DNA that it targets and can therefore be used to analyze extremely small amounts of sample. This is often critical for forensic analysis, when only a trace amount of DNA is available as evidence.

The correct answer is B. He was the first scientist to dissect animals and use them as models for humans in a digestion trial. (i took the test)
Explanation:
Mm
cm
m
kM
The smallest unit among the options is mm(Millimeters). Thus, option a) is the answer.
The smallest unit among the options is "a) mm," which stands for millimeter. It's a metric unit of length that is one-thousandth of a meter (1/1000). Millimeters are commonly used for precise measurements, especially in fields like engineering, science, and manufacturing, where accuracy is crucial.
Centimeters (cm) are larger than millimeters, with one centimeter being equal to 10 millimeters. Meters (m) are even larger, being the base unit of length in the metric system. Kilometers (km) are the largest unit among the options, equivalent to 1000 meters.
In summary, when comparing the given options, millimeters are the smallest unit of length, followed by centimeters, meters, and then kilometers, with each subsequent unit being larger by factors of 10.
The correct option is : a) mm.

Answer:
The the smallest unit among the options provided is mm (millimetre).
Explanation:
mm (millimetre) is a metric unit of length equal to one-thousandth (1/1000) of a metre.
cm (centimetre) is equal to one-hundredth(1/100) of a metre. It is a subunit of length is the SI Sytem. It is used to measure small lengths.
m (metre) is the distance that light travels in vaccum in 1/299792458 seconds. It is the fundamental building block in metric system and is universally accepted.
km (kilometre) is equal to 1000 metres. It is commonly used to measure longer distances.

Answer: A control density dependent limiting factor.
A food processing is a process of increasing the shelf life of preventing the growth of bacteria and improving it's taste. A density dependent limiting factor is the one which affects the size and growth of the population depending upon the density of the population. Food is a density dependent limiting factor as it effects and availability are dependent upon the density of the population.
Food processing is advantageous in a sense as it maintains the quality of food hence, is a control over density dependent limiting factor.
