Applying ice to a wound will constrict the blood vessels, allowing a clot to form more quickly and stop the bleeding. The best way to do this is to wrap ice in a clean, dry cloth and place it on the wound
I think the ice will help the blood clot which will help the wound stop bleeding.
a. Explain why leaves need stomata.
b. Explain why plants need small amounts of minerals. Describe how they obtain these minerals.
Answers
Answer:
Explain why leaves need stomata?
Stomata have two main functions, namely, they allow for gas exchange acting as an entryway for carbon dioxide (CO2) and releasing the Oxygen (O2) that we breathe. The other main function is regulating water movement through transpiration.
Explain why plants need small amounts of minerals. Describe how they obtain these minerals?
Plant roots absorb mineral salts including nitrates needed for healthy growth. For healthy growth plants need mineral ions including: - Nitrate for producing amino acids which are then used to form proteins. - Magnesium is needed for chlorophyll production.
Answer:
stomata allow a plant to take in carbon dioxide which is needed for photosynthesis
Explanation:
plants need small amount of minerals to produce amino acids which are then used to form proteins for plant growth. plants Roots absorb minerals needed for healthy growth

Which of the following best explains why cells that contain the same genetic material do not develop into the same types of cells?
A. Because chemical signals that are released during the cell cycle can result in the linking of similar genes
B. Because internal or external stimuli can trigger the activation of specific genes in the DNA of cells
C. Because messenger RNA is converted to transfer RNA when cell differentiaton begins
D. Because random mutations can occur in the DNA of cells during early embryonic development
Answers
The statement 'internal or external stimuli trigger the activation of specific genes in the DNA of cells' BEST explains why cells having the same genetic material do not develop into the same cells (Option B).
Cell specialization refers to the process by which common stem cells differentiate to produce specialized cells that perform specific functions.Cell specialization is caused by differential gene expression patterns that lead to the expression of different proteins in different types of cells.For example, hematopoietic stem cells differentiate into red blood cells to transport oxygen in the blood by expressing the hemoglobin gene, whose protein binds to oxygen.In conclusion, the statement 'internal or external stimuli trigger the activation of specific genes in the DNA of cells' BEST explains why cells having the same genetic material do not develop into the same cells (Option B).

means that clear water is not
necessarily clean water?
A. the density of the water
B. high specific heat capacity
C. the temperature of the water
D. ability to act as a universal solvent
Answers
Answer:
B
Explanation:
Ability of water to act as a universal solvent means that clear water is not necessarily clean water. Therefore, option (D) is correct.
What is clean water?Clean, safe water is defined by the USGS as "water that won't hurt you if you come in touch with it." Although drinking water is often mentioned when discussing clean water, clean water is also crucial for all residential uses.
It is impossible to smell, taste, or even see the microscopic contaminants that pollute water, such as bacteria, viruses, and parasites. Therefore, just because your water is clear doesn't imply it's okay to drink.
Therefore, due to the fact that water is a universal solvent, meaning that it is capable of dissolving a wide range of substances with relative ease clear water is not considered clean.

In natural selection, organims that are well suited for their environment tend to survive and reproduce. WHen organisms reproduce, they pass their characterisitcs on to their offspring through their genes. Organisms with characters not well suited for their environment are not as likely to survive to reproduce and pass on their characteristics. Organisms that are not able to reproduce and pass on their traits to their offspring die off, or become extinct.

Through these fossilized artifacts, scientists can make conclusions. Some hominid trends include a flatter face as hominids modernized. Refer to diagram M. According to Hominid trends, which of the three jaws would most likely b that of a modern hominid?
Answers
Answer:
The first and second hominids have a more recent common ancestor than the first and third hominids.
Explanation:
The similarity in DNA can definitely reveal us about common ancestry but it does not guarantee that the two species must be mating and reproducing. The best example to support this statement is that humans and chimpanzees share a common ancestor and both have so much similarity in their DNA. The DNA of humans and chimpanzees is around 99% similar but still humans and chimpanzees cannot mate to produce off springs. Several attempts have been made in past to obtain fertile off springs by mating humans and chimpanzees but so far their mating has not produced any fertile off spring.
