Respiration is the process in which food is oxidized to release energy. Complex organic compounds are converted into simpler ones, e.g glucose into CO2 water and energy released.
Breathe in, breathe out. The oxygen that got in lungs is absorbed into blood and carbon dioxide diffuses out of blood into lungs. That's gaseous exchange.
Gaseous exchange is the diffusion of gases from a region of higher concentration to a region of lower one. It is used for the exchange of oxygen and CO2 between organism and its environment.
While using that oxygen to breakdown food and generate energy particles is respiration.

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.

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.
Cornell University recently conducted a study that estimated that honeybees pollinate more than $14 billion worth of crops each year. The study suggested that nearly seventy-five percent of all global crops that are grown for food, fiber, beverages, condiments, spices, and medicines are pollinated. Produced with the help of pollinators, agricultural products including legumes, vegetables, fruits, berries, nuts, herbs, spices, oils, seeds, grains, clover, and cotton make a significant contribution to the economy. As the human population increases, so does the demand for pollination; sadly, the honeybee population is decreasing. Within the past thirty years, parasites, predators, and disease have weakened both wild and managed populations of honeybees. In fact, around the globe, honeybees are being decimated by an epidemic known as colony collapse disorder (CCD).
According to this article, who collected information to research the honeybees?
Answer:
Cornell University collected the information used to research the honeybees.

What is one reason water can remain in the liquid state on Earth?
A. Earth's atmosphere is deep enough to allow water to cycle through
its solid, gas, and liquid states.
OB. Earth's surface is continually bombarded by comets, which add
liquid water.
OC. Earth's distance from the sun keeps the temperature just right for
liquid water to exist.
OD. Earth's atmosphere is warm enough to prevent water vapor from
condensing.

Answer:
c
Explanation:
water boils at 100 degrees Celcius and freezes at zero degrees Celcius. if you want to keep water in a liquid phase, the temperature has to be between 0 and 100 therefore earth is the only planet that is able to keep water in a liquid phase as it is not too hot nor too cold
Because they create multiple alleles, mutations can cause
A. cell division.
B. damaged DNA to repair itself.
C. overproduction of offspring.
D. variations in traits.
Because they create multiple alleles, mutations can cause D. variations in traits.
Gene mutations and evolutionThe production of mutations in DNA molecules is known as mutagenesis. Changes in DNA sequence or chromosome rearrangement are just two examples of mutations that can occur in DNA. These mutations can happen on their own, as a result of mistakes made during DNA replication or mitosis. Natural selection requires genetic variety, which is produced by spontaneous mutations.
The process by which populations of organisms change over generations is known as evolution. These modifications are caused by genetic differences. Different features in an organism can be introduced by genetic differences that modify gene activity or protein function. If a characteristic is beneficial and helps an individual survive and reproduce, it is more likely to be handed down to the following generation (a process known as natural selection).
