The nervous system interacts with the endocrine system by.
A. sending neurotransmitters to endocrine target cells
B. sending neurotransmitters to neuroendocrine cells
C. receiving messages from hormones
D. translating messages from endocrine cells.
Answer:
c. receiving messages from hormones.
Explanation:
a primary function of the sympathetic and parasympathetic nervous systems is to interact with the endocrine system to elicit chemicals that provide another system for influencing our feelings and behaviours.
A gland in the endocrine system is made up of groups of cells that function to secrete hormones. A hormone is a chemical that moves throughout the body to help regulate emotions and behaviours. When the hormones released by one gland arrive at receptor tissues or other glands, these receiving receptors may trigger the release of other hormones, resulting in a series of complex chemical chain reactions. The endocrine system works together with the nervous system to influence many aspects of human behaviour, including growth, reproduction, and metabolism. And the endocrine system plays a vital role in emotions. Because the glands in men and women differ, hormones also help explain some of the observed behavioural differences between men and women.
Suggest ONE reason why some plants have no dispersing seeds
Answer:
Some plants don't use seeds to grow.
Explanation:
For example bananas grown from bulb or rhizome. They are the result of a genetic selection.
Answer:
Plants make seeds that can grow into new plants, but if the seeds just fall to the ground under the parent plant, they might not get enough sun, water or nutrients from the soil. Because plants cannot walk around and take their seeds to other places, they have developed other methods to disperse (move) their seeds.

Gene expression in prokaryotes is regulated at which stage?
A. Translation
B. Transcription
C. Post-transcriptional modification
Answer:
Transcription
Explanation:
This occurs in three steps itself: initiation, elongation, and termination
Initiation (beginning)
- RNA polymers bind to a promoter on a gene
- DNA then unwinds to be "read" by an enzyme
- DNA now ready to make mRNA strand
Elongation (Second step)
- nucleotides are added to mRNA strand
- mRNA molecule is built after RNA polymers reads the DNA that unwound
- adenine (A) in DNA connects to a uracil (U) of RNA while connected to each other
Termination (End)
- RNA will cross a stop sequence in the gene (termination)
- mRNA done and disconnects or detaches from DNA
Hope this helps!

UGA CUG
Below is the base sequence in a segment of one strand of DNA: ACT GAC, and the base sequence in the mRNA that results from this segment of DNA is UGA CUG, which is in option C.
What is transcription and mRNA?The process of transcription is the first step in gene expression, where the information stored in DNA is transcribed into a complementary single-stranded messenger RNA (mRNA) molecule. During transcription, an enzyme called RNA polymerase reads the DNA sequence and synthesizes a complementary RNA molecule using the base pairing rules between DNA and RNA.
Hence, below is the base sequence in a segment of one strand of DNA: ACT GAC, and the base sequence in the mRNA that results from this segment of DNA is UGA CUG, which is in option C.

Compare and contrast the elevated temperature of someone who is exercising vigorously and someone who has an infection.
Answer: seen below
Explanation:
In vigorous exercise, your brain and body do everything they can to cool you off by increase the flow of blood to the skin where it can cool down with the aid of sweating , while in someone who has an infection they push the temperature inside your body to extreme levels by strengthening your immune system resistance to the infection, the immune system deliberately raises your body temperature as part of its strategy to kill the infection attacking you.
Which image models the action of the enzyme helicase in the DNA replication process? A. a sewing machine B. a zipper C. a glue stick D. a copy machine
Answer:
the answer is a zipper
The replication of DNA is a zipper process. An enzyme called helicase is utilized to divide the two DNA strands that are present before DNA replication begins. Thus, option B is correct.
What is the zipper action of the enzyme helicase?Single-stranded DNA is created as a result of this energy-intensive unwinding reaction, which is needed as a template or reaction intermediate in DNA replication, repair, and recombination.
It splits the two DNA strands by unwinding the double helix. Helicase prepares the DNA strands for replication by separating and untwisting them.
It splits the two DNA strands by unwinding the double helix. Helicase prepares the DNA strands for replication by separating and untwisting them.
Therefore, DNA helicases accelerate the breaking of the hydrogen bonds that bind the double-stranded DNA's two strands together.

hurricanes come from
Answer:
Hurricanes are the most violent storms on Earth. They form near the equator over warm ocean waters. Actually, the term hurricane is used only for the large storms that form over the Atlantic Ocean or eastern Pacific Ocean. ... As the wind passes over the ocean's surface, water evaporates (turns into water vapor) and rises.
Answer:
Hurricanes form over the warm ocean water of the tropics. When warm moist air over the water rises, it is replaced by cooler air. The cooler air will then warm and start to rise. This cycle causes huge storm clouds to form.
