Answer: The male reproductive system has many roles, but two are: it <em>produces, maintains, and transports sperm </em>(male reproductive cells)<em> </em>and <em>semen </em>(the fluid which protects the sperm and allows it to swim to meet the female egg). (continued answer in explanation)
Explanation:
One of many structures in the male reproductive system is the prostate gland. The prostate gland's most necessary feature is that it aids in creating fluid that, together with sperm cells from the testicles and fluids from other glands, makes up semen. The prostate also has muscles which ensure that the semen is vigorously pushed into, and then expelled from the urethra during ejaculation. One hormone in the male reproductive system is LH, or luteinizing hormone. It is made by your pituitary gland (a small gland located beneath the brain). LH plays a very important role in the sexual development and functioning of males. LH also plays a key role in gonadal (testicles) function.
When scientists say they share a universal genetic code it means that all organisms it can mean either:
-DNA as the main source of hereditary information in all life forms we know of
or more likely
-that all organisms we know of use a three base pair code for the synthesis of proteins, DNA produces mRNA this mRNA is read three base pairs at a time by a ribosome, this is called the genetic code.
Answer:
0,58
Explanation:
Mice are diploid (2n) organisms, which means that their cells contain two complete sets of homo-logous chromosomes (i.e., they have two copies of any given <em>locus</em>/gene). An allele can be defined as a variant of a gene, whereas diploid (2n) organisms have two alleles at each genetic <em>locus</em>, which are located on homo-logous chromosomes. In this case, we know that there are 580 dominant alleles in a population of 500 individuals, thereby the total number of alleles in this population is 1000 (2n >> 500 x 2 = 1000 alleles), and the frequency of the dominant allele is 0,58 (580/1000 = 0,58).
