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.

Answer:
The PH at which an enzyme will function best is;
In the optimal range
Explanation:
Every enzyme has an optimal pH value which is specific for the enzyme, and where their maximum activity of the enzyme is observed, which is known as its optimal pH
When the enzyme is placed in a different pH, the enzyme activity is observed to be diminishing until the effect of the enzyme stops
This is so because, as the pH of the environment changes, the shape of the active site on the substrate to which the enzyme binds to have an effect changes and the enzyme is no longer able to effectively interact with the substrate
The enzymes in the stomach work best in the acidic environment of the stomach and have an optimal pH of 2, while the enzymes of the small intestine have an optimal pH of 7.5

How does a cell control the process of cell division?
In cell division, the cell that is dividing is called the "parent" cell. Cells regulate their division by communicating with each other using chemical signals from special proteins called cyclins. These signals act like switches to tell cells when to start dividing and later when to stop dividing.
Cells control their division by communicating with each other using chemical signals from special proteins which is known as cyclins.
What is Cell division?Cell division is defined as the process by which a parent cell divides into two daughter cells usually as part of a larger cell cycle in which the cell grows and changes its chromosomes before dividing.
A single cell divides to give rise to two cells where these two cells then divide to form four cells, and so on. This process is called "cell division" and "cell reproduction" because new cells are formed when old cells divide. This plays an important role in all living organisms which is essential for growth, repair and reproduction.
This process helps in:
Renewing of damaged cells. Production of new cells from older ones.Thus, cells control their division by communicating with each other using chemical signals from special proteins which is known as cyclins.

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.

Question: How does carbon move between the atmosphere, hydrosphere, biosphere, and geosphere?
1. Explore: Use the Gizmo to create a path for carbon that begins and ends in the atmosphere. Fill in the
steps in the path below. Then, label each location with the system it represents. Finally, summarize very
briefly how the carbon atom got to that location.
Answer:
Yes.
Explanation:
Yes, everything made or modified by humans with the help of knowledge and education. Without knowledge it is impossible to made new things or modify it. Carbon move from atmosphere to the biosphere by the process of photosynthesis done by plants in order to produce their own food so for that reason the plants take carbondioxide from the atmosphere and change into food whereas in the breathing of organisms this carbon moves again to the atmosphere. Carbon also moves from atmosphere to hydrosphere by dissolved in ocean water and lakes and the volcanic eruption and acid rain causes exchange of carbon between atmosphere and geosphere.
Which of these best explains why mosquito populations show an exponential increase followed by a die off on a seasonal basis with a regular pattern?
Answer:
B) Mosquitoes are limited by temperature, with reproduction levels high in the spring and summer and low in the fall and winter.
Explanation:
Mosquitoes are limited by temperature, with reproduction levels high in the spring and summer and low in the fall and winter.
Answer:
B. Mosquitoes are limited by temperature, with reproduction levels high in the spring and summer and low in the fall and winter.
-Explanation:
Since mosquitoes reproduce when the temperatures are warm, their populations undergo a predictable increase in the warmer months. The first frost will kill many of the larvae and decrease the reproduction of these short-lived individuals.

Explanation:
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).

Most water enters the atmosphere through surface runoff.5. Water vapor warms as it rises. True or False
help help help help helppppp
Answer:
true
Explanation:
this is because as a gas, it needs to cool down, and cool air and humid air is lower than warmer air.
The statements "Most water enters the atmosphere through surface runoff" and "Water vapor warms as it rises" are false.
Evaporation occurs when water is converted to vapor, the amount of evaporation is controlled by the energy available at the surface and the ease with which water vapor can diffuse into the atmosphere.
From the Earth's surface, water is transferred to the atmosphere through evaporation, from surfaces of free water, snow or ice, the ground or vegetation.
Most of water comes from through evaporation of oceans, while the remaining 20% comes from water from continental regions and the transpiration of vegetation.
Condensation occurs in the atmosphere when hot air rises, cools, and its ability to store water vapor decreases.
The hot air, as it rises, cools down for two reasons:.
The air gives up heat to the surrounding masses that are at a lower temperature.As it rises, it supports less and less pressure and expands, this expansion causes its temperature to drop: it cools.In this air mass and on dust particles, the condensation of water vapor begins and the "water droplets" of the cloud are formed.
Therefore, we can conclude that the statements "Most water enters the atmosphere through surface runoff" and "Water vapor warms as it rises" are false.
