a specfic mutation in a certain animal leads to abnormal development of the heart and kidney, resulting in miscarriage. Why did this happen?
Answer:
These kinds of mutations are referred to as Lethal mutations
Explanation:
This type of mutation deleteriously affects the vital genes that are responsible for the core functions of the body. The heart supplies blood to the body organs for nutrients and oxygen while kidneys filter out toxins and end products of metabolism. Mutations in genes for development of these organs will be deadly.

8) What are the differences between asexual reproduction and sexual reproduction?
A) Offspring are produced only by sexual reproduction.
B) An exchange of genetic material only occurs with asexual reproduction. C) Sexual reproduction involves one parent organism, while asexual involves two parent organisms.
D) Asexual reproduction produces offspring identical to the parents, while sexual reproduction produces offspring different from the parents.
Answer:Option D
Explanation:
The continuity of organism on Earth is maintained by the process of reproduction.There are two modes of reproduction. One is sexual reproduction and other is a sexual reproduction.
The asexual reproduction is the process by which identical progeny is produced by single parent. There is no need for two parent.
In case of sexual reproduction the offspring produced is not the exact copy of the parents they show variation. This variation in the offspring provides stability to the organism.

In the pea plant, the allele for green pod color (G) dominates the allele for the yellow pod color (g). The Punnet square illustrates a cross for this trait. Which offspring can be described by these genotypes and phenotypes?
the color of the pea pods will be have a more of a chance to be green due to the fact that there is 75% of the square, because the big G means that it will be that color and if it has (gg) then it will be yellow.
Answer:
a) Homozygous offspring with yellow pod color - gg
b) Homozygous offspring with green pod color - GG
c) Heterozygous offspring with yellow pod color - None
Explanation:
It is given that green pod color (G) is dominant over yellow pod color (g).
Thus, an offspring will have green pod color, when its has heterozygous genotype (Gg) and homozygous dominant genotype (gg). While an offspring will have yellow pod color, only when it has homozygous recessive genotype (gg).
Thus, the offspring with under given phenotypes will have following genotypes -
a) Homozygous offspring with yellow pod color - gg
b) Homozygous offspring with green pod color - GG
c) Heterozygous offspring with yellow pod color - None , a heterogygous offspring will be green in color as green pod color is dominant over yellow pod color.

If the concentration of a sugar solution is lower outside the cell than inside the cell, which will happen by osmosis?
The hypertonic solution has a lower water concentration than the hypotonic solution, so a concentration gradient of water now exists across the membrane. ... On the other extreme, a red blood cell that is hypotonic (lower concentration outside the cell) will result in more water flowing into the cell than out.
Answer:
Water molecules will move out of the cell
Explanation:
We are given that the concentration of a sugar solution is lower outside the cell than inside the cell. This means that a concentration gradient of water now exists across the membrane.
In Osmosis, we know that water molecules move from a less concentrated solution into a more concentrated one.
So in this case, water molecules will move out of the cell.
Which is responsible for muscle pain felt after repeatedly lifting weights
I found out what causes muscle soreness after workouts.

c.
Idea models are typically in the form of a graph or equation.
d.
Idea models are used to show the relationship between variables
the correct answer to this question is b
Answer:
The correct answer is the option A.
Explanation:In science, a model is a representation of an idea, an object or even a process or a system that is used to describe and explain phenomena that cannot be experienced directly. Models are central to what scientists do, both in their research as well as when communicating their explanations.Models are a mentally visual way of linking theory with experiment, and they guide research by being simplified representations of an imagined reality that enable predictions to be developed and tested by experiment.
What happens to the surface to volume ratio as a cell grows
The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume.
As a cell grows in size, its surface area-to-volume ratio decreases due to the cell's volume increasing more rapidly than its surface area. This reduction in ratio can affect the cell's efficiency in nutrient and waste exchange. In multicellular organisms, cell specialization helps mitigate these efficiency issues.
Explanation:As a cell increases in size, the surface area-to-volume ratio decreases. This occurs because the volume of the cell increases faster than the surface area. The surface area of a cell is proportional to the square of its radius, while its volume is proportional to the cube of its radius. Thus, as a cell grows, its volume increases more rapidly than its surface area, resulting in a reduced surface-to-volume ratio.
This reduction in the surface-to-volume ratio can limit the cell's efficiency. If the surface area is unable to support the rate of diffusion required for the increased volume, the cell could struggle to get nutrients in and wastes out efficiently. This is due to the fact that the surface of the cell is where nutrients and wastes exchange occurs.
The solution to sustaining life in larger organisms is for them to become multicellular, allowing for specialization of cells and more efficient exchange of nutrients and waste. For example, some cells specialize in bringing nutrients and removing waste (like circulatory systems) or providing oxygen and removing carbon dioxide (like respiratory systems).
