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:

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.

For each codon, find the correct tRNA anticodon and drag it to the ribosome. Start with the AUG codon
in the ribosome. Find and drag its match, the UAC anticodon, to it. Also, record this pair and the
associated amino acid, Met, to complete the first row of the data table.
PLEASE HELP I DONT KNOW HOW TO DO THIS AT ALL
Drag the correct tRNA anticodon into the ribosome. Therefore, A matches U and C matches G.
What is the UAC anticodon?The Ribosome Workbench uses the AUG codon as a universal signal to initiate translation. Because the methionine-bound tRNA has the anticodon sequence UAC, the AUG start codon signals the ribosome to insert into the amino acid methionine.
What is the correct tRNA anticodon for the mRNA codon 5 GGA 3?1 One codon is 5'-ACG-3'. What is the sequence of tRNA anticodons that bind? Which amino acids does tRNA have? The sequence of the tRNA anticodon is 3'-UGC-5', and the tRNA has the amino acid Thr, the amino acid encoded by the codon.

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 ...
