Are mitochondria found in plant cells, animal cells, or both??
Please help:)
Answer:
Both.
Explanation:
Both animal and plant cells have mitochondria, but only plant cells have chloroplasts. Plants don't get their sugar from eating food, so they need to make sugar from sunlight.
Answer:
Both.
Explanation:
Without mitochondria, cells would not be able to function, no matter what type they are. Mitochondria is the powerhouse of the cell! Hope this helped

Answer:
DNA and RNA
Explanation:
The difference between two molecules include the type of sugar that forms a section of the molecules and the identity of one of the four nigtrogenous bases that make up another section of the molecules. These two molecules are Ribonucleic acid and Deoxyribonucleic acid.
Ribonucleic acid contains Ribose sugar while Deoxyribonucleic acid contains Deoxyribose sugar which is the major difference between the two molecules.

What role does gene expression play in determining traits on an offspring? Explain your response
Gene expression has been defined as the process where the genes produce proteins and RNA. They determine the traits in offspring as various types of proteins pass from parent to offspring.
What is gene expression?Gene expressions are said to be the expression of the genome products in the cell that undergoes the process of transcription and translation to produce the RNA and protein structures that are responsible for providing the phenotype and genotype.
The genes code for the RNA and protein that regulates the amount and type of proteins to be expressed in the offspring that are passed from a parent through reproduction methods. They are hereditary patterns that vary in some amount to make two individuals different from each other.
Therefore, gene expression plays an important role in determining the trait in offspring.

If a strand of DNA has 45% A, what percent will be C?
Answer:
55%
Explanation:
Answer:
[tex]\boxed {\boxed {\sf C=5\%}}[/tex]
Explanation:
There is a method to calculating base percentages known as Chargaff's Rule. It states:
[tex]A+T+G+C=100\%[/tex]
We know the DNA has 45% Adenine or A.
Adenine always pairs equally with Thymine. In other words, the percentage of adenine equals the percentage of thymine (45% Thymine or T).
[tex]45\%+45\%+C+G=100\%[/tex]
[tex]90\%+C+G=100\%[/tex]
Subtract 90% from both sides.
[tex]90\%-90\%+C+G=100\%-90\%[/tex]
[tex]C+G=10\%[/tex]
Cytosine(C) and Guanine(G) pair equally and their percentages will be equal. We can divide 10% by 2.
[tex]C+G=10\% /2[/tex]
[tex]C/G=5\%[/tex]
The percentage of Cytosine or C is 5 percent.

what would happen to your body of blood pressure didn't work as it should?
Answer:
Vision problems. Heart attack. Stroke.
Explanation:
Answer:
Many things.
Explanation:
Blood pressure is a needed thing in a body. It gets blood to your organs and everywhere that needs it. If it didn't work, many things could happen.
Too high BP(hypertension):
If your blood pressure is too high, it can cause ruptured vessels, heart attacks, strokes, heart failure, which is where the heart enlarges too much to continue pumping blood at the adequate pressure/speed, kidney disease/failure, which would be from damage to the arteries around the kidneys, vision loss due to damage to the vessels in the eyes, angina, which is chest pain due to narrowed vessels in the chest, some forms of which may cause heart attacks.
Too low BP(hypotension):
If you're experiencing hypotension, there are many things commonly associated with it. These are dizziness, fainting, nausea, blurred/fading vision, lack of focus, and fatigue. If hypotension becomes extreme, it can cause someone to go into shock, which is life threatening and can and will cause death.

PLEASE HELP QUICKLY! ANSWER AS MANY AS POSSIBLE. DO NOT ONLY SAY "I don't know"
1. How do we know the continents were ever connected (what evidence do we have)?
2. What does the map show about the Earth 225 million years ago ?
3. In what era was the Mesosaurus alive?
4. What animal do you think the Lystrosaurus is related to today and WHY?
Answer:
1. Wegener then assembled an impressive amount of evidence to show that Earth's continents were once connected in a single supercontinent. Wegener knew that fossil plants and animals such as mesosaurs, a freshwater reptile found only South America and Africa during the Permian period, could be found on many continents.
2. It shows that all continents started from a one large land mass. It might be named Pangea. Because people are close to each other, it's so easy to talk and talk about things not just about them but also about other people.
3.Mesosaurus, (genus Mesosaurus), early aquatic relative of reptiles, found as fossils from the Early Permian Period (299 million to 271 million years ago) in South Africa and South America.
4.The Lystrosaurus is a mammal-like animal from the early Triassic period that roamed modern day regions such as India, South Africa and Antarctica over 250 million years ago. It has tusks like an elephant and a beak similar to a turtle, and it was roughly the size of a pig.

Answer:
An important term in genetics that was not used by Mendel was the word "gene", a particle of the chromosome responsible for the traits of a living being. The molecule discovered by Oswald Avery - related to genes and inheritance - was DNA, a discovery he made in 1944.
Explanation:
Despite being considered the father of genetics and providing important information about the inheritance of traits, Mendel did not go so far as to use the term "gene," which is where the alleles responsible for those traits reside. The term "gene" was first used by another botanist, Wilhelm Johanssen, who in 1909 proposed the use of the word gene as the name of the particle responsible for inheritance.
In 1944, the Canadian physician Oswald Avery, faced with the mistaken belief that genes were found in proteins, proposed an experiment where he discovered that the molecule responsible for heredity was deoxyribonucleic acid, or DNA.
