Why is it possible that two ecosystems with identical conditions of temperature and precipitation, could support different plants?
Answer:
Because even if they are similar, they still have a difference between them, and that difference helps other plants.
It is possible because plants require other factors like sunlight and soil nutrients) other than Temperature and precipitation to grow
Plants require some Important factors for its growth and development and they are :
Temperature precipitation Sunlight soil nutrients type of soilThe two ecosystems with identical conditions of Temperature and precipitation might have differences in the amount of sunlight they receive and the Nutrients contained in its soil. therefore the ecosystems although similar can support different plants based on the difference in the amount of sunlight and Nutrients contained in the soil.

what stores and delivers nutrients throughout the cell and transports waste to the cell membrane
[tex] \huge \sf \star{Answer} \star[/tex]
Vacuoles store water, food, and waste. The endoplasmic reticulum (ER) is a series of tunnels throughout the cytoplasm. They transport proteins from one part of the cell to another. Ribosomes are the protein factories of the cell.
Hope it helps uh...The organelle that is responsible for storing and transporting nutrients through the cells is Vacuoles.
Vacuoles are also know as storage containers, they act as a storage organ in the body. This storage organ helps to transport food substances /molecules in the cell. Vacuoles are composed of enzymes, they help to hold water an food molecules. Vacuoles also help to remove waste substances that are harmful to the body.
The vacuole helps to keep balance in the body as they help to keep useful molecules and also get rid of waste substances.

Maria claimed that she could not see through the safety goggles and wore them on top of her head rather than over her eyes. While pouring an unknown chemical into a beaker, she accidently splashed some of the chemical in her eyes. What should Maria immediately do next?
Answer:
She should immediately rinse or flush her eyes with water.
Explanation:
One of the most important precautionary measure to be taken when working with explosive chemicals in the laboratory is the use of safety goggles. However, in this case, Maria claimed that she could not see through the safety goggles and wore them on top of her head rather than over her eyes.
Maria accidentally splashed some chemicals into her eyes while trying to pour it into a beaker. The primary or initial response to this happening is to immediately FLUSH OR RINSE her eyes with water. This will flush away the chemical from her eyes before it can have its detrimental effect.
Answer:
proceed to the eye wash station, open her eyes, and rinse them for at least 15 minutes

A typical virus is made up of 2 parts. Check all that apply.
A) Golgi Body
B) Nuclear envelope
C) Nucleic Acid
D) Capsid
Answer:
C) Nucleic Acid
D) Capsid
Explanation:
A virus is structure that is dependent on a living host to replicate itself. Viruses are majorly pathogenic in nature and have a structure that is made up of two parts namely: nucleic acid and capsid.
The nucleic acid, which can either be RNA or DNA holds the genetic information of the virus while the capsid is a protein coat that enclosed and protects the virus' genetic material. The capsid is also used during the infection life cycle of a virus where it helps the virus to attach to receptor cells on the host's cell membrane.

Which is NOT true of magnetic
domains?
A. Magnetic domains are groups of aligned
atoms.
B. Magnetic domains are too small to be seen.
C. Magnetic domains are outside of a magnet.
The study of magnetic domains is defined as the micro magnetics. The Magnetic domains are outside of a magnet is not true. The correct option is C.
What is a magnetic domain?A magnetic domain is defined as a region within a magnetic material in which the magnetization is in a uniform direction. This indicate that the individual magnetic moments of the atoms are aligned with one another and they point in the same direction.
The magnetic domain structure is responsible for the magnetic behavior of ferromagnetic materials like iron, nickel, etc. The domains are found to be oriented randomly if there is no external magnetic field.
Thus the correct option is C.

Explanation:
Why do deserts tend to form on land at latitudes of 20-30 degrees north and south?
Answer:
Deserts can form even on tropical coasts beside cold ocean currents, such as the west coast of South America. The currents cool the air, which then rises and warms as it moves over land, drawing up moisture that is later precipitated as the air moves farther inland.

Answer:
The correct answer would be -
FSH - used as fertility drugs to makes egg mature.
LS - stimulates the release of eggs.
Oestrogen - causes the lining of the womb to break down.
Explanation:
FSH is a hormone released from the pituitary gland and is the abbreviation of Follicle-stimulating hormone which controls the menstrual cycle and growth of eggs in ovaries. It is also used as a fertility drug that promotes the growth of eggs to mature it.
LS or Luteinising hormone is the hormone that is released from the pituitary gland and promotes the surge of the release of eggs.
Oestrogen is the hormone that helps females during puberty during the menstrual cycle to breakdown the lining of the womb.

What is the effect of inputting stem cells instead of body cells into the original system?
Explanation:
Stem cell research indicates that s.cells are cells that are not fully developed; in turn if researchers inject a patient with type 1 diabetes into the pancreas the result is that the pancreas produces it's own insulin eliminating the chances of spikes in the blood sugars of the patient & also long term effects of high blood sugars that effect all vital organs & nervous system.
Researchers were also using stem cells to limbs that were amputated or damaged resulting in the limb regenerating itself.
I have seen a mouse that had a human ear attached to its body.
Researchers were ordered by our government to cease the experiments because pharmaceutical companies were making more $$ on medicines to supposedly help diabetics or veterans to live a normal life..
Does the Second Amendment need to be "revisited" in 2021? yes and why?
I need help pleasee
Answer:
It needs to be revisited because of the random acts of violence that it enables.
Explanation:
People that have access to weapons of mass destruction use them to kill people for no reason. For example, the sandy hook shooting, the recent Stoneman Douglas shooting, and the Christchurch shooting. All these shootings could have been prevented if there was stronger gun control. If people did not have access to automatic firing machine guns, less people would have died.

Which of the following would cause an error in DNA replication?
A. DNA polymerase pairing A with G
B. DNA ligase connecting chunks of DNA
C. Helicase making a replication fork
D. DNA polymerase checking the DNA
Answer:
A. DNA polymerase pairing A with G
Explanation:
Adenine (A) always pairs with thymine (T), and cytosine (C) always pairs with guanine (G).
DNA polymerase pairing A with G would cause an error in DNA replication. The correct option is A.
An error in DNA replication occurs when an incorrect nucleotide is inserted during the replication process.
DNA polymerase is responsible for synthesizing a new DNA strand by adding complementary nucleotides to the existing template strand.
It ensures the accuracy of replication by matching each nucleotide with its complementary partner (A with T and G with C).
If DNA polymerase pairs A with G instead of A with T, it results in a mismatched base pair.
This is considered an error in DNA replication since it introduces a mutation in the newly synthesized DNA strand.
The fidelity of DNA replication relies on the correct base pairing and proofreading mechanisms of DNA polymerase to minimize errors and maintain the integrity of the genetic information.
Thus, the correct option is A.
