what is the best description of the peidmont region of nourth carolina

Answer:

A and B are both correct.

Explanation:

Chromosomes from both parents are interchanged, which increases the number of possible combinations that the offspring can receive.

Explanation:

The plant cell has a large central vacuole and creates a stronger exterior.

The plant cell has a rigid cell wall and the pressure from the central vacuoles causes the stiffness of the plant and animal cells do not have a cell wall therefore the boundary of the cell is weaker.

The plant cell is stronger because it has the chloroplast and causes a strong boundary that support the cell due to the glucose that is made from the process of photosynthesis.

Answer:

light-dependent reactions or light reactions

Answer:

Monounsaturated Fats: This type of unsaturated fat contains only one double bond in its structure.

EXAMPLE: Stearic acid having chemical formula= C18H36O2

Polyunsaturated Fats: This type of unsaturated fat contains two or more double bonds in their structure.

EXAMPLE: Lenolic acid having chemical formula= C18H32O2

Answer:

Anomalous expansion

Explanation:

Anomalous expansion of water is the abnormal way water expands when exposed to low temperature.

At 4 degree Celsius , the density at the top layer is usually at the Maximum which makes the water sinks down and then the water in the lower layer rises up.

When the temperature drops below 4 degree Celsius, the water molecules at the top then freezes leaving the denser molecules at the bottom which doesn’t freeze as a result of their high density.

This way, organisms can survive in the water due to the lower layer not freezing.

Answer:

Chemical change, exposure to air has caused the apple to turn color, indicating  something new.

Explanation:

Chemical change, exposure to air has caused the apple to turn color, indicating  something new, because it is not asking if cutting the apples is a physical or chemical change, it is asking if the apples turning brown is a physical or chemical change.

Increase in plant and animal diversity describes what might happen with a sudden increase in precipitation in the grassland biome. Therefore, the correct option is C.

Precipitation is the phenomenon in which condensed water vapors falls on the earth's surface under the influence of gravity.

A sudden increase in precipitation in the grassland biome can provide more water for plants and support their growth, which can lead to an increase in plant productivity and diversity. This in turn can provide more food and habitat for animals, leading to an increase in animal diversity as well.

While there may be some nutrient loss and soil erosion as a result of increased runoff, the overall effect on the ecosystem is typically positive in terms of increased biodiversity. Salt and sediment deposition are not typically associated with an increase in precipitation in the grassland biome. Therefore, the correct option is C.

Answer:

120 cm

Explanation:

volume is length x width x height so 3 x 4 is 12 and 12 x 10 is 120cm

Answer:

120 cm^3

Explanation:

V= width x length x height

3 x 4 x 10 = 120

and when you multiply centimeters,

cm x cm = cm^2

cm x cm x cm = cm^3

Answer:

True

Explanation:

As a matter of geological record, the Earth's magnetic field has undergone numerous reversals of polarity. We can see this in the magnetic patterns found in volcanic rocks, especially those recovered from the ocean floors. In the last 10 million years, there have been, on average, 4 or 5 reversals per million years.

Answer:

A food web can be formed by more than one food chain, since the webs includes all possible interactions that can occur between individuals of different trophic levels.

Explanation:

Based on the scheme shown in the image

This food network is made up of three food chains

Food webs often include several food chains, since they are due to the interaction between organisms at different trophic levels, which actually happens within an ecosystem.

In this case, both the insect and the bird are herbivorous organisms, since they feed of the producer, which is the plant.

The only autotrophic organism is the plant, since it is capable of manufacturing its nutrients from sunlight and inorganic matter.

The third order heterotroph is the snake, since it feeds on other animals.  The snake is a carnivore and can be a secondary or more commonly tertiary consumer, so it can be placed in the 3rd or 4th trophic level.

According to the scheme proposed, the bird is omnivorous, since it feeds on both plants and insects.

In this case, the plant, the insect, the bird and the snake are part of more than one food chain.

The bird can be located in both the second and third trophic level, being a primary consumer —when it feeds on plants— or secondary, when it feeds on insects.

Decomposers are generally bacteria and fungi, organisms capable of degrading organic matter, thus enriching the soil. Decomposers can feed on any trophic level.

As the ascent of the pyramid occurs —or at the upper trophic level— the amount of energy available decreases. This is because from one trophic level to another only 10% of the energy can be used. If a plant has 5000 Kcal available, the herbivore that consumes it can only use 500 Kcal.

The main reason for the difference in energy in each trophic level is that energy is lost in each one of them, which the organisms use in their metabolism. A consequence of the metabolism is the loss of energy as heat, which is acquired by the environment.

Answer:

It has physically increased in size. Often, growth of a multicellular organism occurs as more cells are created. In unicellular organisms (like bacteria), growth still occurs. ... For this reason, most biologists will tell you that development only occurs in multicellular organisms, not in unicellular ones.

Answer:

well.. I apologize if I'm wrong but I think it'd be C because ionization is when something basically can go into water and loose part of its' substance to become apart of the water and salt pretty much dissolves completely in water lol

Answer:

The answer is B

Explanation:

Answer:

About 14.75 days

Answer:

Photosynthesis uses energy from the sun in terms of sunlight and cellular respiration uses ATP energy.

Photosynthesis uses energy from the sun and cellular respiration uses glucose to get  ATP energy. Thus option B and D are correct.

The process in which autotrophic plants use light energy from sun and convert it into chemical energy, and prepare their food in the form of glucose called as photosynthesis.

This chemical energy is created from water and carbon dioxide and stored as a sugar molecule, it occur in chloroplasts which has three pigments such as chlorophyll a, chlorophyll b, carotene and xanthophyll.

various factors influence photosynthesis like increase in light intensity causes higher rate of photosynthesis, Higher concentration of carbon dioxide increases the rate of photosynthesis, Temperature range between 25° to 35° C optimum for photosynthesis,

Thus option B and D are correct.
