How do animals get nitrogen that is stored in the soil?
O A) Animals do not take in the nitrogen stored in the soil.
O B) Bacteria change the nitrogen into a gas that the animals breathe.
OC) Plants ab orb the nitrogen from the soil and animals can eat the plants.
O D) The animals can eat the soil and absorb the nitrogen through their digestive system​

Answers

Answer: C) Plants absorb the nitrogen from the soil and animals can eat the plants.

Heterotrophs, specifically herbivores and omnivores, are animals that eat plants (autotrophs) to get the nutrients they need. Those that eat the plants get the nitrogen from the plant that has absorbed it from the soil. Omnivores and carnivores eat the herbivores to get nitrogen that way. For more more information, take a look at the nitrogen cycle.

Max tried an experiment in which he added red-dyed salt water to clear freshwater. He noticed that a lot of the red water sank below the clear water. Which of the following statements explains why this happened?
a. Adding salt to water makes it more dense.
b. Adding salt to water makes it less dense.
c. Adding salt to water decreases its temperature.
d. Adding salt to water increases its temperature

Answers

Answer:

A

Explanation:

Adding salt to water causes its density to increase. Denser water will sink below less dense water.

As salt water is denser and will sink at the bottom and adding the salt raises the temperature of water body and hence will make it more warm and saline.

A max tries to add red dyed salt water to clear the fresh water he sees a red color sinking below the fresh water that is cool.

The option D is correct.

What genotype would a long-haired guinea pig have? ss

Explanation:

I just used S to substitute for my alleles, but you can use any letter. (For example: Ee, EE, ee)

If H is the dominant allele for short hair, we would have the followng genotypes:

Heterozygous short haired: Hh

Pure breeding short haired: HH

Long-haired guinea pig: hh

What is a Dominant Allele?

A dominant allele is an allele of a trait that always expresses itself in the presence of a recessive trait in an allelic pair. Capitral letter is usually used to denote the dominant allele.

Let H represent short hair (dominant allele)

h represents long hair (recessive allele)

Therefore, we would have the following:

Genotype for heterozygous short haired would be: Hh

If number of electrons in an atom is 8 and number of protons is also 8, then
(i) what is the atomic number of the atom? and
(ii) what is the charge on the atom?

Answers

Answer:

i) 8

ii)0

Explanation:

The equal nos of the electrons and protons means it's not a ion, which makes the atomic number equal to them.

Since it is not an ion, the charge shall be 0 since it is neither positively nor negatively charged. The overall charge of an atom is neutral too.

Answer:

(i) atomic number = number of protons = number of electrons = 8

(ii)atom will be neutral (no charge) because number of protons(+) is equal to the number of

Please help me I need to write a 3 sentence​

Answers

Answer:

It can't be fluorite because your fingernail is less on the Mohs scale than fluorite. When an object is less than another object on the Mohs scale it doesn't leave a scratch on the other object. Therefore if your finger leaves a scratch on the material then it has to be less than 2.5 on the Mohs scale. Fluorrite is not less than 2.5 on the Mohs scale so it is impossible that it is that mineral.

**Urgent** Will mark brainliest!

Answers

Answer:

Although these two animals are both bears, clearly they are entirely different. Becasue they live in pretty much opposite environments, they developed individual traits so they could survive, which is called adaption. While the polar bear's thick fur and fat serve as great protection against the cold, it wouldn't be very helpful in hot climates. And the sun bear, with it's short hair and lack of protection, would freeze to death in the polar bear's environment. Each animal, over time, has to develop new traits that allow it to adapt to it's particular environment.

Answer:

These 2 different types of polar bears, may be the same type of animal, but as given in that text, they differ. These 2 different types of polar bears have different types of survival skills, in order to adapt to their environment. The Polar bear in the Northern Hemisphere has very thick fur, and other thick parts in it's body to keep them warm in the ice-covered areas that it lives in so that it wont die, due to the cold. While on the contrary, the bear in the tropical rainforest only has short hair, to keep them at a just-right temperature, so it wont die due to how hot it is. If both of these bears were to switch their environment, then they will die easily since they are not well adapted to that environment.

Consciousness of self is the first abstract problem that the human being solves. Indeed, it is this self-consciousness that removes us from lower animals. This primitive grasp of identity develops with constantly shifting emphasis through all our years. Perhaps maturity is simply the history of those mutations that reveal to the individual the relation between himself and the world in which he finds himself. After the first establishment of identity there comes the imperative need to lose this new-found sense of separateness and to belong to something larger and more powerful than the weak, lonely self.
