Solnce55 [7]
If they are trying to convert any measurements or just measure out the chemicals, it wouldn't be very familiar to them so they could make a mistake that can result of too much or too little of the chemicals, which can make the chemicals react differently.

Can someone pls… im so close to being done
likoan [24]

Answer:

Because liquids flow freely, they take the shape of the container they are in, but have a definite volume. Like liquids, the shape of a gas changes with the container. This is because the atoms in a gas move rapidly and freely to fill any available space. Unlike liquids, the volume of a gas changes depending on the container it is in.

Why would mitochondria in heart muscle cells have more cristae than mitochondria in skin cells?
anyanavicka [17]

Answer:

The structure of mitochondria contains the foldings in the inner side called "cristae" which increase the surface area of the mitochondria. The cristae are important to mitochondria as well as cell as cristae embody the ATP synthase enzymes which help in the formation of the ATP molecules.

Heart cells require more energy to pump the blood from the heart to the body so it needs a more mitochondrial number in the cells with more infoldings to synthesize more ATP.

Compare and contrast the cell cycle with mitosis and the cell cycle with meiosis. Citing atleast 4 similarities and 5 difference
I am Lyosha [343]

Answer:

Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells. Below we highlight the keys differences and similarities between the two types of cell division.

Mitosis is a form of eukaryotic cell division that produces two daughter cells with the same genetic component as the parent cell. Chromosomes replicated during the S phase are divided in such a way as to ensure that each daughter cell receives a copy of every chromosome. In actively dividing animal cells, the whole process takes about one hour.

Meiosis is the form of eukaryotic cell division that produces haploid sex cells or gametes (which contain a single copy of each chromosome) from diploid cells (which contain two copies of each chromosome). The process takes the form of one DNA replication followed by two successive nuclear and cellular divisions (Meiosis I and Meiosis II). As in mitosis, meiosis is preceded by a process of DNA replication that converts each chromosome into two sister chromatids.
