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?
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.

Explanation:
If the temperature of the earth keeps increasing due to the burning of fossil fuels and all other reasons that cause Global Warming, then what all can happen to the earth?
Statement A: Changes in weather.
Statement B: Melting of all the glaciers into water. This will cause an increase in the sea level and widespread decrease in the snow and ice.
Statement C: Afforestation.Required to answer. Single choice.
Answer:
Statements A and B.
Explanation:
Scientists attribute the global warming trend observed since the mid-20th century to the human expansion of the "greenhouse effect" — warming that results when the atmosphere traps heat radiating from Earth toward space. Certain gases in the atmosphere block heat from escaping. Long-lived gases that remain semi-permanently in the atmosphere and do not respond physically or chemically to changes in temperature are described as "forcing" climate change. Gases, such as water vapor, which respond physically or chemically to changes in temperature are seen as "feedbacks."
What three organelles work together to prevent a plant cell from bursting
when it has too much water
The contractile vacuole and the cell wall work together to prevent a plant cell from bursting.
What is turgor pressure?
The pressure exerted by the presence of excess water on the insides of the plant cell is called the turgor pressure. It is maintained with the help of two organelles. These are the cell wall and the contractile vacuole.
The cell wall is the outermost covering of the plant cells. It provides structure and rigidity to the plant cell. When a plant cell is kept in a hypotonic solution, it swells by taking up water by osmosis. The cell wall is an enclosed structure which prevents it from bursting. This condition of the plant cell is called turgidity.
Also, the contractile vacuoles of the plant cell are able to pump out excess water from the water when it has become extremely turgid.
Therefore, the cell wall and contractile vacuoles work together to prevent the plant cell from bursting.

Which of the following is not a phase change that can occur when water absorbs heat?
a
evaporation
b
sublimation
c
condensation

melting
Answer:
C
Explanation:
The condensation is the opposite process of evaporation. And we know that when water absorbs heat evaporation, melting, and sublimation all occur. Leading us to conlude that condensation is not a phase change that can occur when water absorbs heat.
Helppppp please What characteristic of water
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
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.

______ help blood clot following wounds, so that wounds stop bleeding.
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

The answer is heterozygous
Answer: depends on what the dna is. For sure they’ll be hetrodyus
Explanation:
fill in the blanks in the paragraph below using the word bank provided.
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.
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
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).
