Can water change the land quickly, slowly, or both? Explain.
Answer: Yes, but slowly
Explanation: Flowing water causes sediment to move. Flowing water can erode both rocks and soil.
Materials can dissolve in water. With enough time, even rocks can be dissolved by water. This process happens really slowly. It may take over a million years to dissolve a rock. It doesn't matter how big the rock is. With enough time, flowing water can dissolve it. Moving water also has the ability to move small pieces of rock and soil. How can water move a rock? Doesn't it need energy? Of course, water gets its energy because it is moving. Moving water has kinetic energy. Things that have more energy can do more work. When water stops moving it will have no energy. It will no longer be able to move the rock and soil. When this happens the rock and soil will settle to the bottom of the calm water. Scientists call this process deposition. Faster-moving water has more kinetic energy. Therefore, it can carry larger particles. It can also carry more particles. What causes water to move faster? The steeper the slope, the faster the water flows. It's just like a toy car rolling down a ramp. It will roll the fastest when the ramp is steep. It will roll slower when the ramp is less steep. If the ramp is flat, it may have no motion. The slope of the land causes water to move faster. If a stream or a river is flowing down a mountain, it will move more quickly. If it is flowing across a flat area, it will move slowly. Some minerals dissolve in water. The minerals are then carried along in the solution. Small particles, such as clay and silt, are carried in suspension. They are mixed throughout the water. These particles are not dissolved in the water. Somewhat bigger particles bounce along the bottom. Particles, such as sand, move in little jumps near the stream bottom. They are nudged along by moving water. The biggest particles move in a different way. They are too big to hop. Instead, they roll along the bottom. Gravel and pebbles move in this way. These particles roll or drag along the bottom of the water.
Compared to the particles in a solid metal sample, the particles in a liquid metal sample
(1) have a lower temperature
(2) have less kinetic energy
(3) have more kinetic energy
(4) are closer together

What are two possible changes that might occur in a green insect species if the green grass it uses for camouflage turns brown due to drought
I guess evolution could eventually occur causing the insect species to darken but since it's a drought it's probably a short period
another thing is the species is hunted and dies out. their source of camouflage is gone leaving them out in the open for predators

Which of the following fur colors are possible in males? Choose all that apply.
Remember that the S gene for white spots is on an autosome, and the O gene is on the X chromosome.
Black
Black and White
Black, Orange, and White
Orange
Orange and White
Answer:
Black, Black and White, Orange, Orange and White
Explanation:
Black, black and white, and orange, orange and white are the available fur color possible in males due to the S gene present on an autosome.
What is autosome and X chromosome?When a gene is found on one of the numbered, or non-gender, chromosomes, it is said to be on an autosome.
Here, the O genes are found on the X chromosome whereas the S genes for white spots are found on an autosome. As a result, the progeny have fur that is black, white, and orange.
As a result, there are three conceivable fur colors: black, black, and white, and orange, orange, and white.
Therefore, S gene is present on autosome, hence black, black, and white, and orange, orange and white are possible fur colors in males.

The survival function that occurs inside of these structures relies on which three items?
A. sunlight, oxygen, soil
B. oxygen, carbon dioxide, water
C. sunlight, carbon dioxide, water
D. water, xylem, soil
Answer:
This question is incomplete as no structure is portrayed, however, the question can be answered based on general understanding. The answer is
C. sunlight, carbon dioxide, water
Explanation:
The structure being referred to in this question is CHLOROPLAST, which is an organelle in plant cells saddled with the responsibility of making food (sugar) via the process of photosynthesis. In order for the photosynthetic process to occur, three major components or raw materials are needed.
The three items that is relied upon by chloroplast in order to perform its photosynthetic function are sunlight, carbon dioxide (CO2), and water (H2O). The CO2 enters the plant from the atmosphere/air while the H2O is absorbed by the roots of plants. The light is absorbed by certain pigments in the chloroplast called CHLOROPHYLL.
Phagocytosis occurs in many cells. The protist called an amoeba relies on phagocytosis for nourishment. Take a look at the image. Compare this cell undergoing phagocytosis with the human body. What organs in the human body would be represented by A and B? A) A. skin and B. mouth B) A. mouth and B. stomach C) A. stomach and B. vacuole D) A. mouth and B. digestive system
Answer:
I believe D would be the answer
Explanation:
As in the first part the pseudo podium is engulfing the particle which is more similar to taking food and the next part in the phagosome the particle is engulfed and further the enzymes would be released which would digest the particle hence similar to digestion

Why is it important for a person to receive a blood type and Rh factor that is compatible with his or her own blood?
Answer:
Hey!
Here's why its important:-
When a foreign antigen reaches one’s blood, it stimulates the defense mechanism. On receiving unmatching blood, the antigen present in the donor's blood and the antibody present in the recipient's blood will react with each other and form a blood clot. Hence, everyone cannot receive blood from all blood groups.
Answer:
While there are more than 20 blood-type systems, ABO and Rh are the most important ones. The importance of knowing your blood type is to prevent the risk of you receiving an incompatible blood type at a time of need, such as during a blood transfusion or during surgery.

A specific type of flower comes in red, white and pink colors. What pattern of inheritance is being followed? If you were to cross a pink flower with a white flower, what percent of your offspring would be red?
Answer:
Incomplete dominance, 0%
Explanation:
In incomplete dominance, the phenotypes of the dominant and recessive genes are blended. In this case, red and white are blended to create pink.
A Punnett square can be used to determine the phenotypes of the offspring of a white flower and a pink flower. In this case, we'll let "R" represent a gene for a red flower and "r" represent a gene for a white flower.
r r
R Rr Rr
r rr rr
The "Rr" genotype would result in a pink flower, and the "rr" genotype would result in a white flower. It is impossible for this cross to result in a red flower.
Which statement describes a physical property related to the particles that make up a material? A. An iron nail has a reddish color because iron atoms on its surface combine with oxygen atoms B. A fruit has a sour taste because some of the compounds that make it up are acids. C. Salt crystals are hard and brittle because they are made up of atoms that combine by ionic bonding. D. A vegetable has a bitter taste because some of the compounds that make it up are bases.
Answer:
The correct answer would be C. Salt crystals are hard and brittle because they are made up of atoms that combine by ionic bonding.
Explanation: All the other ones are chemical changes because a new substance is formed.
The statement that describes a physical property related to the particles that make up material is as follows:
Salt crystals are hard and brittle because they are made up of atoms that combine by ionic bonding.Thus, the correct option is C.
What is Physical property?Physical property may be defined as a property of matter or substance that is not associated with alterations in its chemical composition.
An example of iron nails involves a chemical reaction to occur and a result of which chemical composition alters. Options B and D are naturally occurring phenomena that do not involve any physical manifestation.

Answer:
El contenedor que tiene fertilizantes crecerá más.
Explicación:
El contenedor que tiene fertilizantes en dosis óptimas crecerá a un ritmo más alto y producirá más vegetación en comparación con otros contenedores que tienen poco o ningún fertilizante porque los fertilizantes tienen los nutrientes que necesitan las plantas en mayor cantidad para su crecimiento y desarrollo.
