How are adaptations related to natural selection?
A. Through adaptation, organisms learn to survive in their
environment. The behavior changes their genes, and they are able
to pass the genes to their offspring. These traits then become
more common within the population.
B. Through adaptation, organisms learn to survive in their
environment. They teach these behaviors to their offspring, so
these traits become more common within the population.
C. Adaptations increase the chances that an individual will reproduce
and pass its genes onto the next generation. Such traits then
become more common within a population.
D. Adaptations increase the chances that an individual will live
longer. As a result, the individual's traits will become more
common within the population.
On an rna molecule, which would base pair with adenine?.
Uracil
Explanation:RNA stands for ribonucleic acid. This helps with the expression of genes.
Bases of RNA
RNA has 4 different bases: adenine (A), uracil (U), cytosine (C), and guanine (G). Next to each base, you can see the symbol that represents the base. These bases are called nitrogenous bases because they contain nitrogen and act as a base (as opposed to an acid). These monomers are one of the building blocks of nucleic acids.
In RNA, adenine and uracil bond, and cytosine and guanine bond.
DNA
RNA and DNA are commonly confused because they perform similar jobs, but nonetheless, they are different. One reason they are different is that DNA does not have uracil. In DNA, adenine bonds with thymine (T).

Challenge: baking powder is a combination of three substances. one is an acid salt, and the other two are
other "known" substances in the gizmo. what are these two substances?
Acid powder and sodium bicarbonate are combined to make baking powder (like cream of tartar). It only requires moisture and heat to activate because it already contains an acid.
What are the characteristics of baking soda?Cornstarch, baking soda, and cream of tartar are the three components. Describe the actions taken by two of these three “active components” in baking powder when water is added to produce bubbles.
When the two active substances are combined with water, a chemical reaction occurs, resulting in the creation of a gas. It is frequently employed in recipes that don't call for the addition of an acidic component.
When wet in a dough or batter, a chemical process takes place that results in carbon dioxide gas and inflates cookies, cakes, and pancakes.
Therefore, baking soda and starch are these two substances.

What is the slope of the line? please help.
Answer:
The slope is [tex]\frac{4}{3}[/tex].
Explanation:
Slope is [tex]\frac{y}{x}[/tex], and to find it we need to look for where the line directly ends on the corner of the graph square. One occurs at (3,4), but the reason the slope is 4/3 and not 3/4 is because it is y over x. The y coordinate lines up at 4 and the x lines up at 3 getting you your answer of [tex]\frac{4}{3}[/tex].

What reactants are involved in photosynthesis?
A. H₂0 and CO₂ and sunlight energy
B. C₂H4O2 and H₂0 and chemical energy
C. H₂O and CO₂ and chemical energy
D. C₂H4O2 and H₂0 and sunlight energy
Answer: A
Explanation:
The three reactants used in photosynthesis are water (H2O) carbon dioxide (CO2), and light (sunlight energy). These reactants are used to produce glucose/food for plants and oxygen that is later released.
H₂0 and CO₂ and sunlight energy are reactants involved in photosynthesis. Therefore, option (A) is correct.
What do you mean by photosynthesis?Plants and other organisms use a process called photosynthesis to transform light energy into chemical energy that can later be released to power the organism's activities through cellular respiration.
C3, C4, and CAM (crassulacean acid metabolism) are the three primary types of photosynthesis. I had to learn some of their pathways and mechanisms.
Its is how green plants use sunlight to make food for themselves. Life on Earth cannot exist without photosynthesis. Without it there would be no green plants, and without green plants there would be no creatures.
