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.

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.

The picture is that of a maize grain.
Answers and Explanation:
a. The label a represents endosperm, b is scutellum (cotyledon), c is coleoptile, d is plumule, e is radicle, f is c is coleorhiza.
b. The function of endosperm is that it helps to supply nutrients for supporting embryonic. It protects the embryo and controls embryo growth by acting as a mechanical barrier during seed development and germination.
c. Hypogeal germination occurs in this seed. In this type of germination, the epicotyl elongates while the cotyledons remain underground.

Explain how damaged DNA in a stem cell could cause a large impact to an organism
DNA damage can affect normal cell replicative function and impact rates of apoptosis (programmed cell death, often referred to as 'cellular senescence'). Alternatively, damage to genetic material can result in impaired cellular function, cell loss, or the transformation of healthy cells to cancers.

Where has the population reached the carrying capacity in the graph shown
above?
A. Point A
B. Point D
C. Point B
D. Point C
Answer: the correct answer is D
Explanation:Carrying capacity is characterized as the maximum populace size that a domain can continue inconclusively. For most species, there are four factors that factor into figuring the carrying capacity of an individual population: food accessibility, water resources, habitat, and ecological conditions.
In a graph representation of population size in a time period increases until it reaches carrying capacity, carrying capacity is representing in the graph where the increase in curve becomes stable and makes a plateau.

4. What steps of the water cycle cause rainy weather conditions? Use the terms
evaporation, condensation, saturation, and precipitation in your explanation. (10
points)
In water cycle, liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow.
What are the characteristics of water cycle?The water cycle, also known as the hydrologic cycle or the hydrological cycle, is a biogeochemical cycle that describes the continuous movement of water on, above and below the surface of the Earth.
The water cycle shows the continuous movement of water within the Earth and atmosphere. It is a complex system that includes many different processes. Liquid water evaporates into water vapor, condenses to form clouds.
The water cycle consists of three major processes: evaporation, condensation, and precipitation. Evaporation is the process of a liquid's surface changing to a gas. In the water cycle, liquid water evaporates and becomes water vapor.

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.
