Answer:

Velocity.

Explanation:

The dependent variable is dependent on the independent variable. Basically, in order for the dependent variable to happen, the independent variable needs to do something first. Usually on a graph, x is the independent variable, and y is the dependent variable. In this situation, the time (x) needs to be graphed in order to track the velocity (y) on the graph.

The other answers are valid, but are not listed on the graph. Unless something is implied with a specific answer (like saying that speed and velocity are considered one on one side of the graph), the other answers wouldn't be correct.

I hope this helps.

Explanation:

Dependent variables receive this name, because in an experiment they depend by some rule on the values of other variables.

here, time (in seconds) is all measured by itself.

but velocity is a measurement that depends on 2 input values : distance (m) and time (s).

so, velocity is the dependent variable.

Scientists use DNA sequencing to understand relationships among life on Earth. The chart illustrates differences between five sp

OlgaM077 [116]

Answer:

With respect to the differences in the DNA sequence of six species, including the human one, it is true that the DNA sequences may vary but the aminoacid sequences are identical.

Explanation:

Options for this question:

The DNA sequences may vary but the amino acid sequences are identical.
The nitrogen bases in the nucleotides must also be different in each.
The process in producing additional DNA, replication, is identical in all six.
The process of producing DNA, or replication, varies due to the differences in the DNA codes.

The different species that exist have specific genomes for each of them, this is the genetic information contained in the DNA varies from one species to another, as can be seen in the scheme (see image). However, the genetic code is universal, and does not vary from one species to another.

The genetic code is found in the RNA molecule and is a sequence of nucleotides that, organized in triplets (codons), are responsible for the synthesis of specific amino acids. An RNA molecule contains the information necessary for protein synthesis.

The scheme shows the differences of five species with respect to the human, based on the respective DNA sequences. But what it does not show is a universally accepted truth, that the nucleotide sequence encoding an amino acid is the same for each of these species.

1. Why does the Elodea cell have chloroplasts but the onion cell does not, even though both are plant cells? Please answer quick

Oksanka [162]

Chloroplasts contain chlorophyll which is what makes plants green. Onions are not green because they do not contain chloroplasts. The reason they do not have chloroplasts is because in the chloroplast, photosynthesis takes place. A key player in the process of photosynthesis is the sun. The onion itself grows underground which means while they grow they do not come into contact with the sun so chloroplasts in an onion is pointless since they can’t undergo photosynthesis. Hope I helped!

How does the Digestive system help maintain homeostasis?

Gnesinka [82]

Answer:

The bacterial flora in the intestines are essential to homeostasis in the body, they not only break down food so the nutrients can be absorbed, they produce vitamins like biotin and vitamin K and guard against harmful bacteria that enter the system. While your heart is a vital organ, the brain (and the nervous system that attaches to the brain) make up the most critical organ system in the human body. The digestive system ordinarily gets 20% to 25% of the oxygenated blood pumped out by the heart and the receptors in muscles provide the brain with information about body position and movement, the brain controls the contraction of skeletal muscle the nervous system regulates the speed at which food moves through the digestive tract.
