(A) The structure is the cell wall. The cell wall protects the cell from damage. It is also there to make the cell strong, to keep its shape.

(B) Structure Z is a chloroplast. Chloroplasts work to convert light energy of the Sun and turn it in to sugars that can be used by the cells. This process is also called photosynthesis.

(C) Since chloroplasts create sugar for a plant cell, fungi has mitochondria. Fungi uses mitochondria which create ATP (also know as Adenosine Triphosphate) which is energy. Therefore, fungi doesn’t need chloroplasts.

The mutation rate is the probability of a single gene mutating in an offspring bug.
Ilya [14]

Answer:

True

Explanation:

A mutation is any alteration in the genetic sequence of the genome of a particular organism. Mutations in the germline (i.e., gametes) can pass to the next generation, thereby these mutations can increase their frequency in the population if they are beneficial or 'adaptive' for the organism in the environment in which the organism lives (in this case, an insect/bug). The mutation rate can be defined as the probability of mutations in a single gene/<em>locus</em>/organism over time. Mutation rates are highly variable and they depend on the organism/cell that suffers the mutation (e.g., prokaryotic cells are more prone to suffer mutations compared to eukaryotic cells), type of mutations (e.g., point mutations, fragment deletions, etc), type of genetic sequence (e.g., mitochondrial DNA sequences are more prone to suffer mutations compared to nuclear DNA), type of cell (multicellular organisms), stage of development, etc. Thus, the mutation rate is the frequency by which a genetic sequence changes from the wild-type to a 'mutant' variant, which is often indicated as the number of mutations <em>per</em> round of replication, <em>per</em> gamete, <em>per</em> cell division, etc. In a single gene sequence, the mutation rate can be estimated as the number of <em>de novo</em> mutations per nucleotide <em>per</em> generation. For example, in humans, the mutation rate ranges from 10⁻⁴ to 10⁻⁶ <em>per </em>gene <em>per</em> generation.

What is an outcome variable? Give an example. (plz i need this)
daser333 [38]

Answer: An independent variable, sometimes called an experimental or predictor variable, is a variable that is being manipulated in an experiment in order to observe the effect on a dependent variable, sometimes called an outcome variable.

Explanation: Example: What is a good outcome variable for deciding whether cancer treatment in a country has been improving?

A first thought might be "number of deaths in the country from cancer in one year." But number of deaths might increase simply because the population is increasing. Or it might go down if cancer incidence is decreasing.  "Percent of the population that dies of cancer in one year" would take care of the first problem, but not the second.

This example makes the point that a rate is often a better measure than a count.
