Attractions between particles hold the particles of liquids and solids close together.
Why is the attraction that particles have for each other not enough to keep gas
particles close together?
Answer:
Kinetic energy is needed to overcome the force of attraction between particles of the same substance. In solids, particles don't have enough kinetic energy to overcome the force of attraction between them. The particles are packed closely together and cannot move around

The mouth generally has a neutral pH close to 7. When salivary enzymes are swallowed and enter into the stomach, which of the following will occur?
a. The enzymes will be deactivated by the change in pH.
b. The enzymes will be activated by the change in pH.
c. The enzymes will be deactivated by inhibitors in the stomach.
d. The enzymes will be activated by coenzymes in the stomach.
The mouth generally has a neutral pH close to 7. When salivary enzymes are swallowed and enter into the stomach, the enzymes will be activated by coenzymes in the stomach. Thus, option D is correct.
What happens when pH is too low in the stomach?
If the pH is too low in the stomach, it will denature the proteins that usually break down food. The major enzyme in the stomach is pepsin, which breaks down proteins in the food we eat. Therefore, the answer is the second statement, "Decrease in pH of the stomach will distort the active site of the enzyme pepsin, which affects its action.

Explain why mutations may or may not affect phenotype
Answer:
Explanation:
Mutations may or may not affect the phenotype because they can occur in coding or non coding areas of the DNA. If they occur in coding areas of the DNA, the protein that is coded in that part could be processed incompletely or have a different amino-acid in some part of its structure, this would affect the phenotype. If they occur in non coding areas, this would have no effect on the phenotype.
When the viral DNA becomes active in the lysogenic cycle, which life cycle does it enter?
A.lytic
B.lysogenic
C.cell cycle
D.DNA replication
Answer:
A.lytic
Explanation:
Lysogenic and lytic cycles are two cycles of viral reproduction. In the lysogenic cycle, the viral DNA is incorporated into the host cell genome. Then, it can be passed on to the cell's daughter cells after it divides.
The other cycle of viral reproduction is called the lytic cycle. In the lytic cycle, the DNA is activated (transcribed). Viral particles can then assemble and replicate, and lyzing the host cell.

Pedigrees and karyotypes provide the means for individuals to identify their risks of genetic disorders. What can be observed on a karyotype but not on a pedigree?
family carriers of a genetic disorder
family history of a genetic disorder
risk of a genetic disorder in offspring
a visual image of a chromosomal defect
Answer:
D) a visual image of a chromosomal defect
Explanation:
The genetic disorders, or inheritance of traits, and abnormality in the chromosome can be studied through pedigree charts and karyotyping.
The correct answer is Option D, a visual image of a chromosomal defect.
The difference between karyotype and pedigree chart can be explained as:
Pedigree charts are the diagrammatic representation of the phenotypes of a particular gene or the lineage of the ancestors. The chart is used to study the inheritance of a trait or a disease. Karyotype refers to the collection of chromosomes, in which disorders or structures of chromosomes are studied. Karyotype provides visual damage or abnormality in the structure of chromosomes.
Thus, the correct answer is Option D.

The following are sources of Earth's internal heat energy EXCEPT
a. Decay of radioactive isotopes
b. Primordial heat
c. pressure from overlying layers
d. Sun’s energy
The sun's energy is not a source of Earth's internal heat. So the correct option is D.
What is the earth's internal heat?
Nobody has even gotten close to directly examining the interior of the Earth. So there is disagreement among geophysicists as to how heated the Earth's core is. However, the speed at which earthquake waves, sometimes known as "seismic waves," move may reveal a lot to scientists about the composition of the Earth.
The solidity, liquidity, or partial solidity of these materials can also be determined using seismic data. Laboratory results, meanwhile, show what pressures and temperatures the materials inside the Earth should melt at.
The temperature of the Earth's core is thought to be between 5,000 and 7,000 degrees Celsius based on this information. That is far colder than the sun's inside, yet roughly as heated as the sun's surface.
Although the amount of heat created inside the Earth is immense, the amount of heat energy received from the sun is around 5,000 times stronger. The weather is influenced by the sun's heat, which ultimately leads to erosion. It is so paradoxical that although the heat of the Earth creates mountains, the energy of the sun gradually breaks them down again.
Therefore the correct option is D.

I will mark you as brainlest if you answer right color blindness (due to a mutation on the x chromosome,a person can't see certain colors (positive or negative or neutral
Answer:
Negative
Explanation:
The mutation that causes color blindness is negative for many reasons. First off, not being able to see color can cause you to not be able to do certain things in life. For example driving, if you can't see the correct colors to know when to stop or go, you can't safely drive. There are also some jobs where colors are important. Such as jobs that have to do with fixing colored wire. It's also bad because of how it takes away one of our senses and holds us back from seeing things and completeness. People who are colorblind can not truly experience the world like a person who can see color can.

Explain how green slugs can be considered both an autotroph and heterotroph
Answer: Green slugs can be considered both an autotroph and heterotrophs because they both are able produce their own food from raw materials and energy and they also consume fruits, vegetables, leaves, and other types of plants.
Explanation: The Yellow slug (Limacus flavus) is a greyish green to olive green slug, which may sometimes even have a yellowish brown colour. ... While the slug's body mucus is yellowish in colour, the sole mucus is colourless. Contrary to the adult slugs, the yellow slug's juveniles have a more greenish colour. Slugs will eat any kind of vegetation but prefer tender leaves. This means that particularly tender-leaved plants or seedlings are very vulnerable to slug damage. Slugs will also eat vegetables and fruits, causing unsightly damage to crops.
