The heart pumps harder and blood pressure rises during a fight-or-flight response. This response is due toa. thyroxine secreted by the thyroid gland.
b. adrenaline secreted by the adrenal glands.
c. insulin secreted by the pancreas.
d. oxytocin secreted by the pituitary gland.

Answers

Answer 1
Answer: The correct answer is letter b. adrenaline secreted by the adrenal glands.
The heart pumps harder and blood pressure rises during a fight-or-flight response. This response is due to adrenaline secreted by the adrenal glands. Adrenaline is a substance that is released in the body of a person who is feeling a strong emotion.

Which organ in the digestive system has a function that is most similar the function of the bladder in the excretory system?(1 point)A. small intestine


B. esophagus


C. large intestine


D. stomach

Answers

The stomach is similar to the function of the bladder in the excretory system. The answer is D. stomach.

The urinary bladder is has inner distensible walls which enables it to serve as a temporal storage of urine up to 500 ml. Its functions also including expulsion of urine form the body.

Based on these functions, the stomach, which is an organ in the digestive system, also act in a similar capacity. The stomach also stores food temporally that are passed down from the esophagus.

See the attachment below for the diagram of the human stomach.

Therefore, the organ in the digestive system that has a function that is similar to that of the urinary bladder is d. stomach.

which part of the brain receives sensory stimuli and passes along the information to the other parts of the brain? A. brain stem B. thalamus C. cerebrum D. hippocampus

Answers

The answer is; B

The thallium receives sensory information, such as visual and auditory, processes the information and passes it to requisite areas of the brain such as the cortex. It acts as the hub for the brain were most signals pass through and are channeled. Thalamus  also plays a significant role in sleep and consciousness of a person.


B. The thalamus acts as a relay station, receiving sensory stimulation and passing it along to other parts of the brain.

In genetic complementation testing, crosses are performed between pure-breeding strains for recessive mutations that confer the same mutant phenotype. If the two mutations are in the same gene, then what phenotypic ratios would be expected among the progeny? A. All of the F1 progeny would display the mutant phenotype associated with the parents.
B. There will be a 1:1 ratio of mutant to wild-type.
C. All of the F1 progeny would be wild-type.
D. All of the F1 progeny would display a novel mutant phenotype that differs from that of the parents.
The answer is not C.

Answers

Answer:

All of the F1 progeny would be wild-type.

If the two mutations are in different genes, then we expect complementation to occur (each mutant strain provides a functional copy of the gene that is defective in the other strain) and wild-type progeny to be produced

Final answer:

In genetic complementation testing, a 1:1 ratio of mutant to wild-type phenotypes is expected in the progeny when the two mutations are in the same gene.

Explanation:

In genetic complementation testing, crosses are performed between pure-breeding strains for recessive mutations that confer the same mutant phenotype. If the two mutations are in the same gene, then the expected phenotypic ratio among the progeny is a 1:1 ratio of mutant to wild-type, which means equal numbers of individuals displaying the mutant phenotype and individuals displaying the wild-type phenotype.

during normal mitotic cell division a parent cell having four chromosomes will produce two daughter cells each containing what

Answers

Answer:

Equal number of chromosomes.

Explanation:

Mitosis may be defined as a type if cell division in which a single parent cells divides into daughter cells. This type of division occurs in the somatic cells of the organism.

Mitosis division is also known as equational division as the number off chromosomes remains equal in the daughter cells. The cells that contain four number of chromosomes, the daughter cells also contains the four number of chromosomes as mitosis is a type of equational division.

Thus, the answer is equal number of chromosomes.

Mitotic division produces diploid cells from diploid cells. So, if the parent cell has four chromosomes, then each daughter cell will also contain four chromosomes.
