what are some drawbacks to using mice in genetic studies?

Answers

Answer:

One drawback to using transgenic, knock-in, and knock-out mice to study human diseases is that many disorders occur late in life, and when genes are altered to model such diseases, the mutations can profoundly affect development and cause early death.

hope this helps

Explanation:

Genetically altered mice have served to recapitulate human diseases, including cancer, glaucoma, heart disease, and diabetes. However, despite their genetic similarity to humans, mouse models are criticized for their failure to accurately mimic human disease phenotypes.

Why it's bad to use mice as an experiment:

The use of mice as model organisms to study human biology is predicated on the genetic and physiological similarities between the species. Mice are less reliable as models of human disease, however, because the networks linking genes to disease are likely to differ between the two species.

Answers

Answer:auditory tube

Explanation

The structure that regulates air pressure between the external atmosphere and the middle ear cavity is known as the Eustachian tube.

What is the structure of Ear?

The ear is a type of organ of hearing and balance which consists of a cavity in the skull structure lined with soft tissue. It surrounds three distinct spaces filled with air or fluid i.e. the outer, middle, and inner ear. These specialized spaces host both the sound transmission apparatus and the sensory apparatus.

Types of bones present in the ear are

1. Hammer shaped bone known as malleus which is attached to the eardrum.

2. Anvil shaped bone known as incus present in the middle of the chain of bones.

3. Stirrup shaped bone known as stapes is attached to the membrane-covered opening which connects the middle ear with the inner ear (oval window).

The cavity of the middle ear is a narrow air-filled space which is a slight constriction divides it into an upper and a lower chamber known as tympanic cavity proper below and the epitympanum above. The main function of the Eustachian tube is to equalize the air pressure between the environment and the middle ear.

Thus, the structure that regulates air pressure between the external atmosphere and the middle ear cavity is known as the Eustachian tube.

How can increases travel boosted the spread of certain species

Answers

Answer:

a

Explanation:

ajiiiiiiiiiiiiiiiiiiiiiiiii

Global travel and spread of certain species
Explanation:
Many pathogenic species of bacteria, virus, and
other microbes are more prevalent in
developing or tropical countries rather than in
developed countries.
When an individual's immune system is weak
they become more susceptible to get infected
and become carriers of that particular species.
The species grows, develops, and multiplies in
the host's body and when the traveler travels to
his/her home country or any other place he/she
can transmit the disease to others and again the
species grows in numbers. Higher the rate of
spread of infection higher is the increase in
species.

Would you expect the cells from the root of a plant to be the same is structure and function as cells from a leaf


please help don't guess.. I have a d in biology and I'm trying to get a better grade. my parents keep hassling me about it please help

Answers

You would not expect cells from the root and leaves to have the same function and structure. This is because they are made for different jobs and are built as such. Leaves may have more chloroplasts containing chlorophyll, thus why they are green, but roots may have few to no chloroplasts, thus why they are not green.

Plants lose __ % water to transpiration resulting in 10% increase in atmospheric water vapor which increases relative humidity and chance of precipitation.

A: 90
B: 10
C: 100
D: 45​

Answers

Answer: A

Explanation: Transpiration is the loss of water from the plant through evaporation at the leaf surface. It is the main driver of water movement in the xylem. Transpiration is caused by the evaporation of water at the leaf–atmosphere interface. Up to 90 percent of the water taken up by roots may be lost through transpiration as only a small amount of that water is used for growth and metabolism.

Answer:

Its "C"  Inversion

Explanation:

I took the test and got it correct

Type of mutation reverses the direction of parts of a chromosome is inversion. The correct answer is option C.

What is the basic structure of chromosome ?

The chromosomes are thread like structures present in the nucleus and the  these chromosomes carry the genetic information in them from one generation to another.

Inversion inverts the structure of chromsome and it basically turns the chromsomes inverted.

Inversion is the process where one arm of the chromosome gets detached from the basic structure and it gets attached in the inverted direction.

This  creates multiple copies of DNA turning it into genetic material and one of the X linked recessive disorders is haemophilia in which same type of mutation caused by the chromosome at the 8th position takes place.

Therefore, Mutation that reverses the directions of the part of the chromosome.

Describe how gravity is associated with many erosional agents.

Answers

Answer:

Gravity is associated with many erosional agents, because the force of gravity tends to pull all material down the slope. is when a rill channel evolves to become deep and wide. glaciers are dense so they can carry large rocks and debris for a long distance.

Role of gravity in erosion, because gravity tries to draw everything down the slope, gravity is linked to numerous erosional agents.

What are erosional agents?

Glaciers and running water both erode due to gravity. This is a result of gravity pulling water and ice downward. These are examples of indirect effects of gravity on erosion.

Due to the force of gravity, mass movement is an erosional process that carries rocks and sediments down slope. The material is moved from higher heights to lower elevations, where it can be picked up and moved to even lower levels by other carrying mechanisms like streams or glaciers.

Therefore, glaciers and running water both erode due to gravity. This is a result of gravity pulling water and ice downward. These are examples of indirect effects of gravity on erosion.
