Answers
Answer:
Vitamin A
Explanation:
Most people with vitamin A toxicity have a headache and rash. Consuming too much vitamin A over a long period of time can cause coarse hair, partial loss of hair (including the eyebrows), cracked lips, and dry, rough skin. Chronic consumption of large doses of vitamin A can cause liver damage.
Consuming too much vitamin A over a long period of time can cause coarse hair, partial loss of hair (including the eyebrows), cracked lips, and dry, rough skin. Chronic consumption of large doses of vitamin A can cause liver damage. It can also cause birth defects in a fetus. Later symptoms include severe headaches and general weakness. Bone and joint pain are common, especially among children. Fractures may occur easily, especially in older people. Children may lose their appetite and not grow and develop normally. Their skin may itch. The liver and spleen may enlarge.

What does RNA have that DNA does not ?
Answers
Answer:
The major difference between DNA and RNA is that DNA is double-stranded and RNA is single-stranded. DNA is responsible for genetic information transmission, whereas RNA transmits genetic codes that are necessary for protein creation. DNA is a long polymer with deoxyriboses and phosphate backbone. Having four different nitrogenous bases: adenine, guanine, cytosine and thymine. RNA is a polymer with a ribose and phosphate backbone. Four different nitrogenous bases: adenine, guanine, cytosine, and uracil.

Which type of mutation reverses the direction of parts of a chromosome?
Deletion
Duplication
Inversion
Translocation
Answers
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.

How can increases travel boosted the spread of certain species
Answers
Answer:
a
Explanation:
ajiiiiiiiiiiiiiiiiiiiiiiiii
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.
Peter is 20 months old, weighs 28 lb, and he wants to eat the same food his older brothers do. No baby food for him; he is a big boy now! His mother is worried that this might not be an appropriate diet for a toddler and asked you, the nutrition student, to check it out. Be prepared for a challenge! It’s not easy to think about all the elements that make a healthful diet at the same time. You have to think about kilocalories, Acceptable Macronutrient Distribution Ranges (AMDR, which by the way are different for toddlers than for adults and adolescents), and watch iron (the most common dietary deficit in toddlers) and fiber intake. And that’s just the beginning. Adequate intake of fluids and electrolytes is also critical for a toddler’s health. Is your head spinning already? Let’s simplify the job by approaching each of the recommended Daily Values separately.

A balanced diet helps to prevent malnutrition in all of its manifestations as well as a number of noncommunicable diseases (NCDs) and illnesses throughout the life course.
What is Diet?However, there has been a change in dietary patterns as a result of increased production of processed foods, growing urbanization, and changing lifestyles.
Nowadays, individuals eat more meals that are heavy in calories, fats, free sugars, and sodium/sodium, and many people eat insufficient amounts of fruit, vegetables, and other dietary fiber-rich foods like whole grains.
Depending on individual characteristics (such as age, gender, lifestyle, and level of physical activity), cultural context, regionally accessible foods, and dietary habits, a diversified, balanced, and healthy diet will take on different compositions.
Therefore, A balanced diet helps to prevent malnutrition in all of its manifestations as well as a number of noncommunicable diseases (NCDs) and illnesses throughout the life course.

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.

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.

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.
