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.

What happens to the tides if the earth spinner fast??
Answer:
it would be a disaster
Explanation:
The centrifugal force would pull hundreds of feet of water toward the Earth's waistline.
Answer:
If the Earth were to spin faster, the tides would change because the fast speeds would increase stress; making tighter circles of convection. This would cause more natural disasters like hurricanes, cyclones, and tsunamis.

What is the mechanism by which the secretion of a hormone is followed by travel to a distant target cell
Answer:
induction or repression of enzymes
Explanation:
Hormones are chemical messengers which are secreted by endocrine glands and regulate the rate of existing activities, usually through the induction or repression of enzymes within distant target cells via the endocrine system. They travel in the bloodstream, having slower, but longer lasting effect and are effective in small quantities.
hope it helps
The mechanism by which the secretion of a hormone is followed by travel to a distant target cell is primarily through the bloodstream. Once in the bloodstream, hormones are carried throughout the body, allowing them to reach their target cells or tissues.
Hormones are usually released in small amounts but have potent effects on target cells. The binding of a hormone to its specific receptor triggers signaling pathways within the target cell, leading to changes in cellular function or gene expression.
The travel of hormones through the bloodstream ensures their widespread distribution and enables them to reach distant target cells located in different organs or tissues.
This mechanism allows hormones to exert their regulatory effects on various physiological processes, including growth and development, metabolism, reproduction, and homeostasis.

Many industrialized countries exist in an ecological deficit due to their lack of productive land, overproduction of waste, or low freshwater supplies. Which scenario describes a way to create an ecological surplus for an industrialized country?
Import beef and soy products into the country
Export garbage and wastes to other countries
Change farming techniques to conserve soil
Allow unlimited freshwater resources for all
Answer: change farming techniques to conserve soil
Explanation:
The scenario that describes a way to create an ecological surplus for an industrialized country is the change farming techniques to conserve soil. The correct option is C.
What are farming techniques?Farming technology, the system of practices used in crop production The goal of agricultural technique is to ensure high crop yield with minimal labor and capital investment per unit of realized product.
The circumstance that characterizes a manner for an industrialized country to generate an ecological excess is changing farming techniques to conserve soil.

Which equation shows how matter is transformed and conserved in photosynthesis? In other words, which is the balanced chemical equation for
photosynthesis?
O 602 + 6H2O + Sunlight → CH208 + 6CO2
O 6CO2 + 6H2O + Sunlight → CH,20g + 602
O CH120o + 6CO2 → 602 + 6H20 + Sunlight
son
CH,208 + 602 → 6CO2 + 6H2O + ATP
Answer:
B
Explanation:
The reactants of photosynthesis are CO2 and H2O and the products are C6H12O2 and O2
the answer is not exact, but it is the closest to the actual equation
The equation shows how matter is transformed and conserved in photosynthesis is O 6CO2 + 6H2O + Sunlight → CH,20g + 602. Thus, option B is correct.
What is photosynthesis?Photosynthesis can be described as a process which plants use to produce their own food. In this process, carbon dioxide and water get converted into sugar (glucose) and oxygen. Light energy from the sun is needed for this reaction to occur. The excess oxygen produced by this process is released into the atmosphere. The sugar made is used as fuel by the plant.
Cellular respiration is the process by which living organisms obtain energy by breaking down food molecules. Cellular respiration can occur in the presence of oxygen (aerobic) and this combines glucose molecule to form carbon dioxide (CO2) and water (H2O) and release energy for use.
The equation best models cellular respiration is: C6H12O6 + 602 = 6H20 + 6CO2 + Energy (ATP). The reactants of photosynthesis are CO2 and H2O and the products are C6H12O2 and O2.
Thus, option B is the correct option.

What does RNA have that DNA does not ?
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.
