function of a mitochondion
Answer:
mitochondria are to produce the energy currency of the cell, through respiration, and to regulate cellular metabolism.
Explanation:
the role of mitochondrion is to generate the energy commodity of the cell, by respiration, and control of cell metabolism.Mitochondrial is the ATP synthesis site for the cell. The amount of mitochondria present in a cell is also a strong predictor of the cell 's rate of metabolic activity; cells that are very metabolically active, such as hepatocytes, may have more mitochondria.

Explanation:
Define natural selection and give Example with detailed explanations.
Answer:
Natural selection is when animals who are able to survive in their environment flourish, and those animals who aren't die out.
Explanation:
Lets say there were two rival animals, we can call them plantoids 1 and 2. These plantoids were both trying to out-survive each other. The problem is birds loved to eat them, so through evolution plantoids 1 began producing toxins, so when chewed on the bird would be poisoned. For awhile this worked, and the plantoids without it were dying off. Then plantoids 2 created a thorn on their heads, and were able to blend well. This worked well, and sadly for plantoids 1 the birds were able to eat them. The birds went through natural selection and those who were immune to the poison survived. Now these two plantoids are two completely different species, and they were once the same. In the end plantoids 2 survived because they were more adapted to the setting they lived in.

The picture shows a contractile vacuole of a unicellular freshwater organism. The contractile vacuole regulates the flow of water into and out of the cell in an aquatic environement. What condtions cause the contracile vacuole to fill with water? Your answer: The concentration of water is greater outside the cell than inside the cell. The concentration of water inside the cell is the same as the concentration outside the cell. The temperature of water in the vacuole is higher than the temperature of its environment.
Answer:
The concentration of water is greater outside the cell than inside the cell.
Explanation:
In living cells, water moves by Osmosis across the cell membrane, which acts as the semi-permeable membrane. Osmosis is the movement of water molecules from a region of high water concentration (low solute concentration) to a region of low water concentration (high solute concentration).
The contractile vacuole of this freshwater organism helps regulate water intake and exit by storing excess water. According to osmotic flow, water will flow into the organism via its cell membrane (semi-permeable membrane) because the concentration of water outside the cell is high than inside the cell, hence, this causes an osmotic gradient causing water to flow into the cell. The water that flows into the cell is stored in the Contractile vacuole.

In transcription within the nucleus, RNA is made
through
pairing with the
antisense strand in
DONE
Answer:
The correct answer is - Base pairing rule and DNA.
Explanation:
According to the base pair rule during transcription, along with antisense strand DNA, the RNA was made and the bases of the purines and pyrimidines strands bind together, Uracil paired with the A-strand and the C strand being paired to G-strand in transcription within the nucleus.
Thus, the correct answer in the first line is "Base-pairing rule" while in the second line is "DNA".
Answer: The answers are In transcription within the nucleus, RNA is made through
✔ base
pairing with theantisense strand in
✔ DNA

Why do you think there is a ring with a dark gap within the body of the wood?
How would pH levels decrease due to production of fatty acids
Answer:
Fatty acid synthesis is the creation of fatty acids from acetyl-CoA and NADPH through the action of enzymes called fatty acid synthases. This process takes place in the cytoplasm of the cell. Most of the acetyl-CoA which is converted into fatty acids is derived from carbohydrates via the glycolytic pathway.

4. If you are male, which member of your family should you look at to tell whether you are going to
go bald? Why? Use a punnett square to prove your answer.
Answer:
Your mother
Explanation:
If you are a male, the member of the family you should look at to tell whether you are going to go bald is your mother.
Baldness is a sex-linked recessive trait and as such, the two X chromosomes in females need to carry the allele in order for females to be phenotypically affected for the disorder. The males having only one X chromosomes however, means that they only need that single X chromosome to carry the baldness allele in order for them to be affected for baldness.
Assuming the allele for baldness in represented by b. Your mother is affected for baldness while your father is free from the disorder. This means that the genotype of your mum would be [tex]X^bX^b[/tex] while that of your dad would be [tex]X^BY[/tex]. According to law of inheritance, males usually inherit their X chromosomes from their mother. This means that any male your mother gives birth to would have the genotype [tex]X^bY[/tex] which phenotypically means that they will be affected for baldness.
The attached image shows the Punnet's square analysis of what will happen during inheritance.
