Answer: Humans and greater primates excrete water, broken down proteins and Urea. Many things cause unusual urine, Urea gives urine its yellow color a lack of urea can mean kidney failure. however it's hard to tell a lack of urea by just looking at urine as drinking excessive amounts of water turns the color clear and drinking caffeine turns the color reddish or brown so lab testing must be done

Sensory neuron(s) then transmit information from the sensory receptor(s) to the Central Nervous System

Explanation:

These receptors are located all over the body but some types of receptors are in specific areas of the body (e.g. taste receptors in the mouth).

Sensory neuron(s) then transmit information from the sensory receptor(s) to the Central Nervous System (i.e. the brain and spinal cord, sometimes referred to in the abbreviated form: C.N.S.). This is happens because peripheral nerves all connect to the spinal cord via the network of nerves within the nervous system.

The information so received by the C.N.S. is further transmitted by relay neurone(s) with the C.N.S.

Explain the role of insulin in the homeostatic regulation of blood glucose levels
Xelga [282]

Answer:

Insulin helps the cells absorb glucose, reducing blood sugar and providing the cells with glucose for energy. When blood sugar levels are too low, the pancreas releases glucagon. Glucagon instructs the liver to release stored glucose, which causes blood sugar to rise.

Hope this helps!

All of the following are true of spermatogenesis EXCEPT: Question 18 options: DNA replicates once, but cells divide twice. The p
jolli1 [7]

Answer:

  • One spermatogonium produces 4 spermatids FALSE. One primary spermatocyte produces 4 spermatids.

Explanation:

Germ cells are diploid reproductive cells in charge of gamete production. Germ cells divide by mitosis and meiosis. Through mitosis, they originate more sexual cells, but through meiosis, they produce gametes -sperm and egg cells-. This process is known as gametogenesis.

Gametes´destiny is to merge during fecundation, and a new diploid cell called zygote emerges through fertilization. The zygote is a complete cell and suffers successive mitosis to form the new organism.

Spermatogenesis is the process of production and maturation of sperm cells. Spermatogonia are the masculine diploid germ cells, carrying 46 chromosomes. These germ cells suffer mitosis to reproduce. Some of them stay as spermatogonia, and some others become primary spermatocytes, which are in charge of gamete production. Primary spermatocytes are also diploid cells, meaning that they still carry 46 chromosomes.

Each primary spermatocyte replicates its genetic material and then goes through meiosis I to produce two daughter haploid cells called secondary spermatocytes, each of them carrying 23 chromosomes. Each secondary spermatocyte will produce two other haploid daughter cells by meiosis II.

The total result from the two cellular divisions of each primary spermatocyte is four haploid daughter cells called spermatids.

During spermiogenesis, spermatids mature into spermatozoa or sperm cells. Each sperm cell characterizes by being composed of a head, midpiece, and tail.

  • DNA replicates once, but cells divide twice TRUE
  • The products are spermatozoa that each have a head, midpiece, and tail TRUE  
  • Spermatids containing 23 chromosomes (1n) are produced TRUE
  • One spermatogonium produces 4 spermatids FALSE. One primary spermatocyte produces 4 spermatids.
  • Genetically diverse spermatids are created TRUE

Suppose you can read the sequence of bases on only one strand of the double helix. What would you use to figure out the sequence
olchik [2.2K]

Answer:a). base pairing rules

Explanation: A DNA is a double stranded helix in which the two DNA strands are antiparallel and complementary to each other. Watson and Crick developed the base pairing rules that adenine pairs with thymine and cytosine pairs with guanine. The complementary strand are not the same in base sequence and composition instead anywhere adenine is found in one strand, thymine is found in the other strand and anywhere cytosine is found in one strand, guanine occurs in the other strand.
