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

As the Earth warms overall, insects are shifting toward the poles to colonize areas that are warmer than before in the summer months. Yet many of these insects lack the ability to survive the colder winters found in these regions. ... As the days stay warmer later into the fall, insects' bodies get confused.

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.

Explain the versatility of carbon atoms. Why is carbon the base element for all life's molecules?
Answer:
Life is based on carbon; organic chemistry studies compounds in which carbon is a central element. The properties of carbon make it the backbone of the organic molecules which form living matter. Carbon is a such a versatile element because it can form four covalent bonds.

1) Sembrar 5 granos de maiz en cada uno de los siguientes recipientes sustratos, arena, canto rodado, arcilla, tierra negra abonada. 2 Medir semanalmente por un mes su crecimiento. Describe lo observado y redacta conclusiones de la experiencia
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. El fertilizante contiene nitrógeno, fósforo, potasa y algunos otros nutrientes que contribuyen al crecimiento y desarrollo del cuerpo de la planta, por lo que podemos concluir de este experimento que el contenedor con nutrientes crecerá más rápido que otros.

An increase in the concentration of greenhouse gases, like carbon dioxide, in the atmosphere can increase the temperature on Earth. How would such an increase in temperature most likely affect Earth's water cycle?
Answer:
Global warming intensifies water cycle
Explanation:
Global warming can dramatically intensify the water cycle because this phenomenon is associated with an increase in temperature, thereby a higher amount of water is evaporated into the air and a higher amount of ice is melted at the poles. Warmer atmospheric air will have a higher amount of water vapor, increasing the frequency and intensity of rainstorms. In consequence, global warming can significantly increase the probability of flooding in coastal communities.

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.

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.
