PLEASE HELP , WILL GIVE BRAINLIEST. In Mendel’s first experiment, he crossed tall plants with short plants and found tall plants were dominant to short plants. Draw a Punnett square to describe this experiment and list the genotypes and phenotypes of the offspring.
PLEASE HELP, WILL GIVE BRAINLEIST. Explain the difference between primary and secondary succession. please not such a simple answer
Answer:
Primary succession begins on a newly exposed surface
while secondary succession begins on soil.
Primary succession basically takes place on "lifeless" areas as result of a disturbance for example, Glaciers and lava flow from valcanos.
Secondary succesion begins from things such as forest fires or an abandon field.

Imagine that all of the sunlight is blocked from reaching Earth's
surface. What kind of organisms would be impacted first? *
O producers
O primary consumers
O secondary consumers
O tertiary consumers
O decomposers
Answer:
The correct answer is - producers.
Explanation:
Producers are organisms that are capable of making their food and energy on their own with the help of light energy get from the sunlight. These are the base of any ecosystem due to the fact that all the organisms depend directly or indirectly on the producers for food and energy.
So, if all the sunlight is blocked from reaching the earth's surface producers will be affected first in terms of ecosystem and trophic level.
Thus, the correct answer is - producers.
What changes when a cell divides into two daugther cells to make it easier for the cells to exchange materials across the surface of the cell? A. Cell division does not make it easier to transfer materials across the cell surface. B. The new cells move materials faster. C. Each new cell has an increased surface area to volume ratio
The new cell has an increased surface area to volume ratio is a process that makes easier the exchange of materials across the surface of the cell (Option C).
What is cell division?Cell division is the process by which cells generate new daughter cells, which may be due to mitosis or meiosis in higher organisms.
Cell division is able to increase the surface/volume ratio and therefore it facilitates the movement of materials in the resulting cells.
In conclusion, news cell has an increased surface area to volume ratioand it makes easier the exchange of materials (Option C).

C. Embryos are frequently fossilized and illustrate change over time.
D. Embryos go through various stages that suggest the animal’s evolutionary process.
Answer:
Embryos go through various stages that suggest the animal’s evolutionary process.
its right
Embryos help scientists that Embryos go through various stages that suggest the animal’s evolutionary process.
What is structural evidence for evolution?Observing anatomical features shared between organisms (including ones that are visible only during development) can indicate that they share a common ancestor.Structural evidence can be compared between extant (currently living) organisms and the fossils of extinct organisms.EmbryologyEmbryology is important to understanding a species' evolution since some homologous structures can be seen only in embryo development. For example, all vertebrate embryos, from humans to chickens to fish, have a tail during early development, even if that tail does not appear in the fully developed organism.Thus, we can conclude that embryos go through various stages that suggest the animal’s evolutionary process.

Which of the following is not a health risk associated with ozone?
A) skin cancer
B) cataracts
C) obesity
D) respiratory illneses
Answer:
obesity
Explanation:
The following that is not a health risk associated with ozone is obesity. The correct option is C.
What is ozone?Ozone is a trioxygen inorganic molecule that is of pale blue color. The ozone layer is present in the stratosphere of the atmosphere. It absorbs the UV rays coming from the sun. Thus, it is a protective layer that saves from UV rays.
UV rays are harmful rays that affect health. It creates skin problems and many other health problems. So the ozone layer protects us from UC radiation, it acts as a shield.
Obesity is a condition in which the body becomes fat. It happens with the accumulation of fat in the body. This does not occur with UV rays. It occurs due to food. So this will not be a health risk associated with ozone.
Thus, the correct option is C. obesity.

C) respiratory
D) skeletal
This organ is the primary organ of the integumentary system. It protects, regulates, and prevents water loss. It is your
A) brain.
B) kidneys.
C) skeleton.
D) skin.
1. The correct answer would be C) respiratory system.
Respiratory system is made up of set of organs which help in taking in oxygen and expelling out carbon dioxide from the body.
In humans, it is composed of nose, pharynx, larynx, trachea, bronchi, pair of lungs, and diaphragm.
Alveoli (in lungs) are the site of gaseous exchange where oxygen is exchange with carbon dioxide.
Carbon dioxide is the toxic waste product of cellular respiration. Circulatory system helps in transporting CO₂ from cells to the alveolar site where it is exchanged with oxygen and excreted out as a part of exhaled air.
2.The correct answer would be D) skin, hope this helps
Each of the following changes will result in increased blood flow to a tissue except Each of the following changes will result in increased blood flow to a tissue except increased vessel diameter. increased blood pressure. relaxation of precapillary sphincters. increased hematocrit. decreased peripheral resistance.
Answer:
The question above is written twice, and without options attached. For comprehension, I would re-write the question with the options attached
Each of the following changes will result in increased blood flow to a tissue except
a. increased vessel diameter.
b. increased blood pressure
c. relaxation of precapillary sphincters
d. increased hematocrit
e. decreased peripheral resistance.
The correct answer is Option D (increased hematocrit)
Explanation:
An increase in vessel diameter would lower resistance, thereby increasing blood flow to the tissue.
An increase in blood pressure would increase blood flow to a tissue. This statement is true provided the blood pressure taking blood to tissue is not increased in the arteries.
The relaxation of precapillary sphincters which regulate the flow of blood through capillaries would cause increased blood flow to a tissue.
A decreased peripheral resistance, which means a decrease in resistance of the arteries to blood flow would increase blood flow to a tissue.
While increased hematocrit means increased red blood cells in the total volume of blood causing more thickened blood resulting in reduced blood flow to a tissue.

why do cells have to stay within a certain size range in order to maintain stable conditions? Explain how surface area and volume are related to this phenomenon.
Answer:
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.
Explanation:
hope this helps :D
The important point is that the surface area to the volume ratio gets smaller as the cell gets larger.
What is Surface area?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.
A solid object's surface area is a measurement of the overall space that the object's surface takes up.
In comparison to the definition of arc length for one-dimensional curves or the definition of surface area for polyhedra (i.e., objects with flat polygonal faces), where the surface area is equal to the sum of the areas of its faces, the mathematical definition of surface area in the presence of curved surfaces is significantly more complex.
Therefore, The important point is that the surface area to the volume ratio gets smaller as the cell gets larger.
