Answer:
The periodic table of elements includes only elements.
Explanation:
All the materials on Earth are made up of the same elements, which can be found on the periodic table. These elements combine to form compounds, or mixtures such as water, a compound of hydrogen and oxygen, or air, which is a mixture of nitrogen, oxygen, carbon dioxide (a compound!) and many other gases, even water vapor. It is the combination of these elements in different ways that gives us so many different substances. Hope this helps!
Answer:
Explanation:
Elements are pure substances with only one type of atom.
The substances on Earth are created when two or more elements are combined.
Because elements can combine to form compounds, more substances can be created on Earth.

Most forms of vaccination consist of injecting a person with inactive viruses. How do the proteins from the inactive viruses protect the person from later infections by those viruses?
A. The proteins cause a mild infection that prevents the person’s body from responding to later infections.
B. The proteins bond with receptors on the cells of the person so that later active viruses cannot bind with them.
C. The proteins stimulate an immune response, which produces memory cells that can generate antibodies when new active viruses try to infect cells.
D. The proteins remain in the body and serve as a food source for later active viruses instead of feeding on the person’s tissues and causing the infection.
Answer:
C
Explanation:
Because when you get a vaccine the proteins and bacteria are working against each other so when the doctor says its normal to run a low fever thats why.

Some scientists are modifying the genetic code of certain fish by inserting genes that cause the fish to produce more growth hormone, which causes the fish to grow more quickly. Salmon is one type of fish on which scientists are working. Which answer choice shows the most significant negative impact to society that could result from producing genetically modified salmon?
Salmon cells could become less responsive to the hormone over time, slowing the growth rate of the fish.
Salmon could be reintroduced into the ecosystem where they could breed with, and alter, populations of wild salmon.
The genetically modified salmon will be very expensive to raise, so the fish will be too expensive for people to buy.
The modified, farmed fish would be more difficult for predators to hunt than wild salmon if reintroduced into the ecosystem.
Answer:
breeding with and altering the population of wild salmon
the extra growth hormone could change the wild salmons reproductive fitness, could slow them down or make them less fertile or more fragile so they aren't able to spawn etc and reduce the wild population of salmon which would have large effects
there is a rainforest in BC that's survival relies on the nutrients that salmon bring when they spawn and die
It could also be scare mongering and have no negative effect, could be a net positive??

The diagram below shows a microscopic view of the lower epidermis of a maple leaf. The cell indicated by the letter B is a guard cell. Guard cells are found on each side of the stomata.
Which of the following statements correctly describes how guard cells affect the physiological processes in a leaf?
A. Guard cells shrink to let in pollen for plant reproduction and swell to keep in oxygen.
B.Guard cells shrink to let in carbon dioxide for photosynthesis and swell to limit transpiration.
C. Guard cells shorten to let in light for photosynthesis and elongate to keep water from entering the cell.
D. Guard cells become rounder to let in oxygen for cellular respiration and flatten out to block the release of carbon dioxide.
Answer:
D is the answer of your quest.
Explanation:
D
The statement that correctly describes how guard cells affect the physiological processes in a leaf is as follows:
Guard cells shrink to let in carbon dioxide for photosynthesis and swell to limit transpiration.Thus, the correct option is B.
What is Photosynthesis?Photosynthesis may be defined as a type of process through which green plants and photosynthetic algae generally prepare their own food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.
Guard cells generally mediate the opening and closure of stomata. With the help of this activity, they regulate the rate of transpiration. Guard cells swell up and open the stomata for the exchange of gases when the plant has an excess of water and other useless gases. These types of cells are generally identified by their kidney-shaped appearance that surrounds the stomata.
Therefore, the correct option for this question is B.

An air mass acquires the temperature and humidity of its source region.
True
False
An air mass acquires the temperature and humidity of its source region is a true statement, an air mass is a substantial volume of air that contains both temperature and humidity.
What is an air mass?As the name implies, an air mass is a substantial volume of air that contains both temperature and moisture. The temperature will change depending on where the air mass is located, for instance, the temperature will always be lower in the center of the air mass.
Similar to how air mass humidity fluctuates, air mass humidity will not change when air temperature decreases.
However, depending on the environment, it may either gain or lose water mass. Temperature and humidity may change at any time, but the pressure never does.
Therefore, air mass acquires the temperature and humidity of its source region is a true statement.

What is another term for the responding variable?
O primary variable
dependent variable
independent variable
uncontrolled variable
The answer is DEPENDENT VARIABLE
-edgy 2021
Answer:
B. Dependent variable.
Explanation:
An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).
Hence, an experiment is used by scientists or psychologists to illustrate how a change in variable affects behavior.
This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.
In an experiment, there are two (2) main types of variables and these are;
I. Independent variable: this is the variable that is being manipulated or alters and as such it is the cause of a behavior. This variable stands alone.
II. Dependent variable: this variable is the direct effect of the actions of the researcher in an experiment.
Basically, the dependent variable is the variable that is being measured and tested by an experimentalist.
Hence, dependent variable is another term for the responding variable because it responds to an action.
why is DNA replication called simi conservative
Answer:
As the DNA double helix is unwound by helicase, replication occurs separately on each template strand in antiparallel directions. This process is known as semi-conservative replication because two copies of the original DNA molecule are produced. Each copy contains one original strand and one newly-synthesized strand.
Explanation:
If a molecule is too large to pass through a cell membrane, it will need to use a
