a. It produces the greatest change in high and low tides.
b. It produces the least change in high and low tides.
c. It produces semidiurnal tides.
d. It produces diurnal tides.
Answer: The combined gravitational pull of the Sun and moon cause high tides in the path of the alignment, meaning that low tides occur at ninety degrees from the path of the solar eclipse. Due to inertia, the high tides also occur on the opposite side of the Earth from the solar eclipse.

The process by which sperm is made is called
Answer: The process of producing mature sperm is called spermatogenesis. Sperm are produced in the seminiferous tubules of the testes and become mature in the epididymis. ... Spermatogonia lining the seminiferous tubule undergo mitosis to form primary spermatocytes, which are also diploid.
Explanation:
A male generative cell is called sperm. Sperm comprises a head, body and tail. It is an important reproductive gamete in males that combines with the egg to produce offspring.
The process by which sperms are produced is called spermatogenesis.
The male reproductive cell forms in the male reproductive gland called the testes.From one male germinal cell (2n) four sperm (n) are produced.Spermatogenesis undergoes mitosis and meiosis.By the process of spermiogenesis, the spermatid receives nourishment and grows into sperms.Therefore sperm are produced by spermatogenesis.

What are the roles nucleic acid plays on living system?
Answer:
The functions of nucleic acids have to do with the storage and expression of genetic information. Deoxyribonucleic acid (DNA) encodes the information the cell needs to make proteins. A related type of nucleic acid, called ribonucleic acid (RNA), comes in different molecular forms that participate in protein synthesis.
Explanation:
When does
transcription
happen?
Answer:
Transcription begins when RNA polymerase binds to a promoter sequence near the beginning of a gene (directly or through helper proteins). RNA polymerase uses one of the DNA strands (the template strand) as a template to make a new, complementary RNA molecule. Transcription ends in a process called termination.
Explanation:
Transcription Initiation. The first step in transcription is initiation, when the RNA pol binds to the DNA upstream (5′) of the gene at a specialized sequence called a promoter (Figure 2a). In bacteria, promoters are usually composed of three sequence elements, whereas in eukaryotes, there are as many as seven elements ...

how does the nervous system help the excretory system maintain homeostasis?
Answer:
The nervous system maintains homeostasis by controlling and regulating the other parts of the body. A deviation from a normal set point acts as a stimulus to a receptor, which sends nerve impulses to a regulating center in the brain.
Explanation:
The nervous system keeps the body in a state of homeostasis by controlling and regulating excretory system.
What is Homeostasis?In a broad sense, homeostasis refers to a system's stability or balance. It's the body's endeavor to keep its internal environment consistent. Internal environment stability necessitates regular monitoring and modifications as conditions change. Homeostatic control refers to the balancing of physiological systems within the body.How does nervous system regulates homeostasis?Because the nervous system does not store nutrients, it must get them from the bloodstream on a regular basis. Any disruption in blood flow might result in brain injury or death.The nervous system keeps the body in a state of homeostasis by controlling and regulating the other organs. A variation from a regular set point stimulates a receptor, which transmits nerve impulses to a brain regulating area.learn more about homeostasis here:
