Answer:
As an example of an exaptation, Gould (1991) used the large size of the human brain and its function of enabling humans to produce speech. The large brain size, according to his argument, originally arose as an adaptation for some (unspecified) functions in humans' ancestral past ( Gould, 1991 ).

HELPPP!!! What would the mass of an artificial cell containing 20mL of a 25% sugar solution be after it was placed in a beaker containing a 30% sugar solution for 30 minutes? Remember to include units in your answer.
Answer: The sugar will move from the 50 % concentration to the 0 % concentration.
Explanation:
Dialysis is an analytical technique which uses a semipermeable membrane in order to remove the impurities from the body.
This technique is used when the kidney failure inside the body takes place. The kidney inside the body perform function of filtration, when kidney failure takes place then the dialysis is used.
In this case the tubing bag containing 0% sugar is put into a sugar solution having 50% solution.
After sometime the sugar will move from 50 % to 0% bag because of the phenomenon known as osmosis.

In fission, how does the DNA of the daughter cells compare to the DNA of the parent cells?
It is exactly the same
It is different due to meiosis
It it mostly the same with slight changes
It is better than the parent DNA
Answer: It is exactly the same!
In fission, the DNA of the daughter cells compared to the DNA of the parent cells will be exactly the same. The correct option is A.
What do you mean by a parent cell and a daughter cell?The cell that divides to produce two daughter cells is known as the mother or parent cell in the process of cell division. Mitosis produces two offspring cells that are genetically identical to the mother cell. We are all alive now due to a process known as mitosis.
Mitosis is the process through which a single cell divides into two new, identical cells. The initial cell is known as the parent cell, while the newly created cells are known as the daughter cells.
The daughter cell is exactly identical to the mother cell, that's why the DNA will also be the same in both cells.
Therefore, the correct option is A. It is exactly the same.

C) reservoirs
D) all the above
Answer:
the answer is a
Explanation:
Volcanic eruptions, breathing, decaying dead matter, burning fossil fuels, and warm bodies of water are all carbon examples of sources. Therefore, option (A) is correct.
What are sources of carbon?Carbon is one of the most important elements for life on Earth, and it can be found in a variety of sources. Some of the most common sources of carbon include:
Fossil fuels: coal, oil, and natural gas are all made from carbon-based materials that have been buried and transformed over millions of years.Plants: Plants take in carbon dioxide from the atmosphere during photosynthesis and use it to build their tissues.Animals: Animals obtain carbon by eating plants or other animals.The ocean: The ocean contains dissolved carbon dioxide, which can be absorbed by marine organisms and transformed into calcium carbonate, a key component of shells and other structures.Soil: Carbon is stored in soil as organic matter, such as decaying plant and animal material.The atmosphere: Carbon is present in the form of carbon dioxide, methane, and other gases in the atmosphereLearn more about carbon sources, here:

The hydrophobic effect is related to the fact that water is most stable when it has the most hydrogen bonds and that nonpolar molecules decrease the number of those bonds. True or false
Answer:
True
Explanation:
When a hydrophobe is dropped in an aqueous medium, hydrogen bonds between water molecules will be broken to make room for the hydrophobe; however, water molecules do not react with hydrophobe. This is considered an endothermic reaction, because when bonds are broken heat is put into the system. The hydrophobic effect is considered to be the major driving force for the folding of globular proteins. It results in the burial of the hydrophobic residues in the core of the protein. It is exemplified by the fact that oil and water do not mix and was described well by G. S. Hartley in 1936. 1 Hydrophobic effect. The hydrophobic effect increases the thermodynamic activity of large hydrophobic molecules of metal complexes formed in the aqueous phase of solvent extraction systems, which promotes their transfer from the aqueous to the organic phase.

How do you think the rock layers and fossils found in Red Rock Canyon can provide evidence for Earth's geologic history? What types of information can scientists learn from fossils?
Answer:
Fossils found in Canyon are crinoids, brachiopods, and sponges.
Explanation:
The rock layers and fossils found in Red Rock Canyon can provide evidence for Earth's geologic history because the canyon has marine fossils such as crinoids, brachiopods, and sponges and also contains terrestrial fossils such as impressions of leaf, dragonfly wing, scorpions, centipedes, and reptiles. So we can say that Red Rock Canyon provides a lot of evidences about geological history. The scientists learn a lot of information from fossils such determine the age of the rock, relation of different organisms with one another and ancient environments.

The examples of geological processes that occur slowly is soil erosion and weathering.
What do you mean by soil erosion?Soil erosion is the denudation or wearing away of the upper layer of soil. It is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice, snow, air, plants, and animals.
Soil erosion occurs primarily when dirt is left exposed to strong winds, hard rains, and flowing water. In some cases, human activities, especially farming and land clearing, leave soil vulnerable to erosion.
Removing trees and plants, plowing fields, and overgrazing by livestock disrupts roots that stabilize sediment and soil. These human activities can increase erosion rates 10 to 100 times that of non-human geologic processes.

Which of the following characteristics of a population will make it better able to adapt to environmental changes?
A.Rapid production of many offspring.
B.Specialization in one type of food source.
C.Large amount of inherited genetic variation.
D.Isolation to a limited geographic range.
Answer:
C
Explanation:
Answer: C. Large amount of inherited genetic variation.
If you had a population where the genetic variation wasn't as high or practically non-existent, then that population is likely suited to that very narrow specific environment. If the environment doesn't change, then the population wouldn't have a problem. However, the environment isn't likely to stay static. Things change all the time and this change will bring challenges to the population that was suited for the old environmental conditions.
Populations with high genetic variability will have some individuals thrive while some unfortunate members will perish. The members that die off are likely the ones who cannot adapt to the changes. As the environment changes, the individuals who survive will pass on their DNA to their offspring, allowing for natural selection to reinforce those favorable traits. Since the environment is constantly changing, whether that change is slow or fast, this means the process is continued indefinitely. So that's why high genetic variability is favored.
What do variations create?
Variations in species help them to adapt themselves to that particular environment and give them a chance of survival. For example, thermophilic bacteria are variants that are resistant to extreme temperature. They have a chance of survival in high temperate zones while others die.
