What is the difference between an autotroph and a heterotroph?

Answers

Answer:

Autotroph produces its own food (Plants)

Autotrophs are known as producers because they are able to make their own food from raw materials and energy. Examples include plants, algae, and some types of bacteria. Heterotrophs are known as consumers because they consume producers or other consumers. Dogs, birds, fish, and humans are all examples of heterotrophs.

How does the double helix structure of DNA explain how the molecules can be copied or replicated

Answers

Answer:

How does the double-helical structure of DNA explain how the molecules can be copied or replicated? Because of base pairing, each strand has all the information to serve as a template for the other strand.  DNA replication occurs only during the S phase of the cell cycle.

Because of base pairing, each strand has all the information to serve as a template for the other strand.  DNA replication occurs only during the S phase of the cell cycle.

What is DNA?

Humans and nearly all other species carry their genetic information in DNA, also known as deoxyribonucleic acid. The DNA of an individual can be found in almost all of their cells.

The majority of DNA is found in the cell nucleus (where it is known as nuclear DNA), but there is also a tiny quantity of DNA in the mitochondria (where it is called mitochondrial DNA or mtDNA). Cellular organelles called mitochondria transform the energy from food into a form that can be utilized by cells.

Adenine (A), guanine (G), cytosine (C), and thymine (C) are the four chemical bases that make up the code that stores the information in DNA (T).

Therefore, Because of base pairing, each strand has all the information to serve as a template for the other strand.  DNA replication occurs only during the S phase of the cell cycle.

Answers

Answer:

-saliva

-hydrochloric acid

-pancreatic juices

Explanation:

When the food such as carbohydrates enters our mouth, the saliva enzyme starts break down of that carbohydrate. Then the food enters the esophagus and then reaches the stomach. In stomach, hydrochloric acid  is present which helps in digestion of food. Then the food enters the small intestine and their pancreatic juice is present which also helps in break down of sugars, fats, and starches.

A woman without hemophilia marries a man with hemophilia they have a daughter with hemophilia what is the genotype of the mother and father

Answers

Answer:

Mother- XXH

Father- XHY

Explanation:

The mother is a carrier for hemophilia and since the disease is sex linked and found on the X chromosome, only one of the alleles has that H allele attached to it. The father is male so he only has one X chromosome, which is why he is effected by the disease and not just a carrier like the mother.

WHY DOES WATER HAVE A HIGH SPECIFIC HEAT? WHAT IS THE SPECIFIC HEAT OF WATER?

Answers

Answer:

Depends on the temperature of it's surroundings.

Explanation:

Answer:

There are two reasons. One of them is that the water molecule is “bent”. It is rotationally asymmetric, meaning that it can “store” more energy in the rotational degrees of freedom than other, symmetric molecules (like diatomic molecules, or CO 2  for example).

The other and more important reason are the hydrogen bonds. When a hydrogen atoms binds with a more electronegative atom (such as oxygen in the case of water), its electron has a higher probability to be found in the vicinity of the oxygen atom, leaving the hydrogen nucleus partly “exposed”. This partial charge on the hydrogen will create a very weak bond with the partly negatively charged oxygen atom of a neighbouring water molecule (remember, the hydrogens’ electrons prefer to be around the oxygen atom instead, making it a bit negatively charged). This electrostatic interaction, or bond, between neighbouring water molecules is the famous hydrogen bond.

Even though each hydrogen bond by itself is weak compared to the bonds in the molecules themselves, there are many neighbours around each water molecule, which means that water can store a significant amount of energy in these bonds. As you add heat to water, instead of speeding up the molecules (increasing their kinetic energy and thus temperature) the hydrogen bonds get broken up, soaking in the additional heat without much change in temperature.

A response is a “reply” or a “reaction.” Use this information to explain why the health damage that results after exposure to a harmful chemical is called a response.

Answers

a response to exposure would mean that your body is reacting to the harmful chemical. when your health is at stake, your body reacts with a response. for example, if you get a chemical in your eye, you start tearing up and your eye turns red. that's a response to the chemical.

A chemical substance is a stimulus which produces a response or reply in the body.

What is a stimulus?

A stimulus is a factor or agent that produces a response in the body of a living organism.

When a stimulus is received by the body, it produces a response.

A harmful chemical that is introduced to the body is a stimulus which could cause damage to the body.

The response the body produces to the chemical substance would be to help the body recover.

Therefore, a chemical substance is a stimulus which produces a response or reply in the body.

Phylogeny can be based on morphological homologies and molecular homologies. What are the advantages and limitations to using each

Answers

Answer:

1. Molecular data:  

- Advantages:  

a. less susceptible to evolutionary convergence

b. huge amount of potential characters available for data comparison (each nucleotide can potentially be used to assess the state of a character)

c. useful for assessing times of divergence

- Disadvantages:  

a. multiple sequence alignments are hard to solve for sequences with high evolutionary rates

b. limitation to the number of states of the character

c. generally unuseful for comparing with data from extinct species

d. difficulties of inferring positional homology

2. Morphological data:

- Advantages:  

a. useful to understand the evolutionary significance of traits in extinct ancestral species

b. there is not limitation to the number of different states of the character

- Disadvantages:

a. susceptible to evolutionary convergence

b. limited number of characters is available

Explanation:

Morphological and molecular data are the two primary sources of information used to infer homology. In the last years, molecular data gained ground for this purpose. However, it should be stressed that molecular data only have 4 different states (i.e., 4 different types of nucleotides), while for morphological data in principle there is not limitation to the number of different states. On the other hand, morphological traits are more susceptible to evolutionary convergence, thereby leading to spurious results when assessing the homology of problematic characters. Finally, it is important to highlight that morphological data are generally more useful to understand the origin and homology of traits in extinct species.

How did the Invention of the cotton gin affect slave labor in the United States? My life is really depending on you guys!! Many years ago, parrots could talk just as humans do. Parrots always told the truth, so people greatly admired them. There was one old parrot who lived with a dishonest man, in a little house on the edge of town. This parrot was known in the town to be wise, honest, and good. One night, the man went out and stole his neighbors ox, and, the next day, the neighbor came to the thiefs house with several other people. She banged on the wooden front door until the thief answered. Did you steal my ox? asked the angry neighbor. Of course not, said the thief. Lets ask the bird, said another woman. He is always honest. They asked the bird, and he said Yes, he did steal the ox. What proof is the word of a bird? asked the thief. This bird cant be trusted because he doesnt always tell the truth. The people were unsure of what to do next, so they went away to think about it, promising to come back the next day. The thief knew he had to find some way to get his neighbors to not trust the parrot. They had to believe that the bird didnt always tell the truth. The clever thief came up with a plan. That night, while the parrot was sleeping next to the window, he placed a large dome over the birds cage. Then, he poured water over the top of the dome. The bird awoke to see water falling. He thought it must have been raining outside. He tried to go back to sleep but was awoken again by loud noises. The man was banging on the floor with a stick, out of the birds sight. The next morning, the neighbors came back. The thief said, I can prove that this bird is a liar. Ask him what the weather was last night. The bird told them, Last night there was a great thunderstorm. The people couldnt believe it! There was no storm last night. It was a clear night. The bird was a liar! They were so angry that they told the bird to go into the forest. The parrot was sad. After all, hed done nothing to deserve this. A mockingbird asked why the parrot was sad, and the parrot told his story. Why didnt you just repeat the words you heard, like I do? asked the mockingbird. People always like to hear their own words. What the man said wasnt true, the parrot replied. People dont always want to hear the truth, answered the mockingbird. Say what they say, and theyll think youre a wonderful bird. From then on, the parrot only repeated the words of people.Select the THREE correct answers.How does the man tricking the bird move the story forward? 1. It leads to the man telling the people that the bird lies sometimes.2. It leads to the people thinking that the parrot is a liar. 3. It leads to the parrot deciding to repeat only what people say. 4. It leads to the parrot being sent to live in the woods.5. It leads to the parrot telling the people that the man stole the ox.
