Answer:
b. Theories unify a broad range of observations and hypotheses.
Explanation:
In broad terms, theories are the set of principles that can or must be used to explain certain phenomena. It involves the involvement or inclusion of any set of principles to get to a conclusion.
Hypothesis, on the other hand, is just a term used for an assumption made. And this assumption may be made even before any observation has been done, a mere suggestion for how to proceed with things or an assumption about things.
Thus, scientific theories unify a broader range of observations that had been done, including any hypothesis. So, the correct answer is option b.

Explanation:
A sample of human blood was placed in a test tube containing a
physiological saline solution (0.9% sodium chloride). This type of solution is
often used intravenously to quickly rehydrate patients. A drop of the blood
from the test tube was placed on a slide and red blood cells (RBCS) were
observed under a microscope. Three possible outcomes are diagrammed
below. Which of the following best predicts which diagrammed
microscope view the laboratory worker would see and best explains why?
View 1 because RBC membranes are freely permeable to water
View 2 because the RBCs use energy to allow sodium entry and to pump water out
View 2 because the rate of water movement into the RBCs equa's the rate of water
movement out of the cells
Vien 3 because the sodium-potassium pumps in the RBC membranes use energy to
Veep the codum out but a water to free to the des
Answer:
View 2
Explanation:
The rate of the water movement into the RBCs equals the rate of water movement out of the cells <3
The statement that best predicts diagrammed microscope view the laboratory worker would see is View 2. This is because the rate of water movement into the RBCs equals the rate of water movement out of the cells.
What is Microscope?A microscope may be defined as a type of laboratory instrument which is utilized to examine objects that are too small to be visualized by the unaided eye.
According to the context of this question, if a sample of human blood was functionally placed in a test tube containing a physiological saline solution.
This means that a concentration of salt is present in it. Due to this, the rate of migration of water into the RBCs is equal to the rate of water migration outside the cell. This is because the conditions are ideal for RBCs with respect to a specific cell.
Therefore, the correct option for this question is C.

How does an insect species become resistant to an insecticide?
There are some offspring already resistant to the insecticide's effects that survive and reproduce.
After an exposure if the insect survives, it mutates to become resistant if it encounters it again.
The more exposure an insect has to the insecticide the weaker the effects of it are.
After exposure, all the reproductive cells have mutated to become resistant for the next generation.
Answer:
I believe you just answered it yourself. they development an immunity to insecticides the more they are exposed to it.

The correct group involved in the peptide links of amino acids is CO-NH.
In the process of forming peptide bonds, the carboxyl group (-COOH) of one amino acid reacts with the amino group (-NH2) of another amino acid, resulting in the formation of a peptide bond. This reaction is known as a condensation or dehydration synthesis reaction, where a molecule of water is eliminated. The carboxyl group (-COOH) loses an oxygen atom and the amino group (-NH2) loses two hydrogen atoms, which combine to form a water molecule. The remaining components, the carbon (C) from the carboxyl group and the nitrogen (N) from the amino group, form the peptide bond, resulting in a CO-NH linkage between the two amino acids.
Therefore, the correct group involved in the peptide links of amino acids is CO-NH. This peptide bond is a crucial component in the formation of proteins, as amino acids are linked together through peptide bonds to create polypeptide chains.

Why is water so susceptible to pollution?
A) It occurs naturally as a solid, liquid, and gas
B) It can be found underground
C) It is a universal solvent
D) Only 3% of Earth's water is freshwater
Answer:
I believe its (A) hope that helps
Water so susceptible to pollution because it occurs naturally as a solid, liquid, and gas. Hence option A is correct.
What is pollution?Pollution is defined as the contamination of the land or soil that hinders the development of natural life. Sulfur dioxide and other hazardous gas emissions contribute to acid rain, global warming, and other factors that make it difficult for animals to thrive. These factors include rising temperatures, unpredictable rain patterns, and droughts.
The majority of the freshwater on the planet is inaccessible to humans. A little more than 69 percent of the freshwater on Earth is trapped in glaciers and polar ice caps as ice, and another 30 percent is present beneath the surface as groundwater.
Thus, water so susceptible to pollution because it occurs naturally as a solid, liquid, and gas. Hence option A is correct.

What are two ways that Nitrogen can get "fixed" to be used by plants
Answer:Nitrogen in its gaseous form (N2) can’t be used by most living things. It has to be converted or ‘fixed’ to a more usable form through a process called fixation. There are three ways nitrogen can be fixed to be useful for living things:
Biologically: Nitrogen gas (N2) diffuses into the soil from the atmosphere, and species of bacteria convert this nitrogen to ammonium ions (NH4+), which can be used by plants. Legumes (such as clover and lupins) are often grown by farmers because they have nodules on their roots that contain nitrogen-fixing bacteria. (Learn more about this process in the article The role of clover.)
Through lightning: Lightning converts atmospheric nitrogen into ammonia and nitrate (NO3) that enter soil with rainfall.
Industrially: People have learned how to convert nitrogen gas to ammonia (NH3-) and nitrogen-rich fertilisers to supplement the amount of nitrogen fixed naturally

Many birds live in mountainous temperate forest ecosystems. Above the tree line on mountains, however, the ecosystems change. Few birds are found there. Many factors contribute to the lower number of birds seen above a mountain's tree line. Which of these factors is abiotic?
Answer:
Abiotic means something dead. Its not that hard.
Explanation:
The abiotic factors which can affect the number of birds living on the tree line in temperate mountain forest ecosystem is the frequent high winds. Thus, the correct option is C.
What factors affect ecosystem?An ecosystem consists of the community of organisms together with their physical environment in which they live. Ecosystems can be of different sizes and can be aquatic or terrestrial. Different categories of the terrestrial ecosystem are known as biomes. In ecosystems, both the matter and energy are conserved.
An ecosystem is not a stable system however it depends upon several factors which include both biotic (living) and abiotic (non-living) factors. Any disturbance in these factors could results in disturbance of ecosystem as a whole.
The factors include light, temperature, water, chemicals, gases, wind and soil. In some environments, like marine environments, pressure and sound are the important abiotic factor. In the mountain ecosystems, frequent high winds is an important abiotic factor.
Therefore, the correct option is C.
