Explanation:
A student studying aquaculture is interested in how diet and water temperature affect the growth rates of fish. She hypothesizes that fish receiving a high protein diets and in warmer temperatures will have enhanced growth rates. She has four treatment groups:______
a. Fish tanks in a laboratory at 22 degrees C and high protein diet.
b. Fish tanks in a laboratory at 22 degrees C and low protein diet.
c. Fish tanks outside with a temperature of 26 degrees C and high protein diet.
d. Fish tanks outside with a temperature of 26 degrees C and low protein diet.
Answer:
Explanation:
This question is not complete below is the remaining part of the question. Is her hypothesis a true hypothesis or merely a prediction? (Has she provided rationale for her hypothesis?)
Do you think this is a good experimental design? Do you have suggestions for how she could improve her experimental design?
Answers:
The result of the experiment will determine if the hypothesis will be accepted or rejected and further explanation will be given to the effect.
Increase in dietry protein will subsequently increase the body weight as such the result show should tend towards a positive response to an increase in protein level.
The experiment design is completely randomized design(CRD) and it is good for the experiment to have the temperature all monitored and a close watch on the fishes.

Explanation: The correct answer is option A because it is the only answer where it occurs in both prokaryotic and eukaryotic cells.
Option A: Proteins are assembled on ribosomes. is correct.
Cells fall into following two broad categories.
Prokaryotic EukaryoticProkaryotes are single-celled creatures belonging to the Bacteria and Archaea domains. Eukaryotes include animal cells, plant cells, fungus, and protists. Prokaryotic cells do not have a nucleus. Cells with a nucleus are referred to be eukaryotic cells. Aside from the nucleus, eukaryotic cells have other organelles. Ribosomes are the only organelles in a bacterial cell.
Proteins are assembled on ribosomes.

Which place on an enzyme binds a substrate?
High levels of salt (Na Cl-) can disrupt the tertiary structure of proteins. What effect do you think increasing concentrations of salt would have on lactase activity
Increasing concentrations of salt would disrupt lactase activity by disrupting its tertiary structure. This enzyme breaks down lactose.
What is an enzyme?An enzyme is a protein that acts to lower the activation energy of a given chemical reaction.
Lactase is an enzyme that acts to break down lactose (a disaccharide) into galactose and glucose.
Different conditions in the media (in this case, concentrations of salt) may disrupt enzyme activity by altering its tertiary 3D structure.

The photograph shows rockweed. Which feature allows rockweed to
withstand the constant wave action of its environment?
A. The ability to carry out chemosynthesis
B. The ability to firmly attach to rocks
C. The ability to produce its own light
D. The ability to carry out photosynthesis
Answer:
B
Explanation:
This is the answer because if the rockweed is able to firmly attach its self to the rocks it would be able to withstand the constant wave action
The tendency to firmly attach to rocks allows rockweed to withstand the constant wave action of its environment.
RockweedIt is a brown alga and grows in the rich intertidal zone.
The holdfast of a rockweed permits it to withstand the constant wave action of its surroundings.
Holdfast is a tiny stem-like composition which allows the weed to anchor firmly to the rocks.
The rockweeds possess some of the advantages over the normal weeds that permits them to sustain in water like the intense developed root systems.
Thus, the correct answer is option B, that is, the ability to firmly attach to rocks.

Which are the four major groups of human pathogens?
A. bacteria, Viruses, Fungi and Protists
B. Protists, insects, bacteria and viruses
C. Fungi, Protists, Toxins and Bacteria
D. Viruses, Fungi, Protists and Toxins
Bacteria, Viruses, Fungi and Protists are the four major groups of human pathogens. Therefore, option (A) is correct.
What are human pathogens?Bacteria are microorganisms that are made up of a single cell and can be the source of illnesses such as strep throat, TB, and infections of the urinary system. The common cold, influenza, and COVID-19 are all illnesses that can be caused by viruses, which are non-living particles that can only multiply inside of a living host cell.
Infections such as ringworm, athlete's foot, and thrush can be caused by fungi, which are multicellular organisms that can spread from person to person. Protists are single-celled organisms that are capable of causing a variety of diseases, including giardiasis, malaria, and amoebic dysentery.
Insects and toxins, despite the fact that they are capable of inflicting harm on humans as well, are not considered to be major classes of human pathogens.

An exoplanet is a planet in a different solar system than the one in which we live. Scientists have discovered many exoplanets that are many light years away. Predict which pattern is true about exoplanets.
O Exoplanets would orbit their own stars instead of the Sun
O Exoplanets have a large mass
Exoplanets have many moons
Exoplanets orbitour Sun
Answer:
Exoplanets would orbit their own stars instead of the Sun
Explanation:
Our solar system is defined by the planets and other celestial objects which orbit the sun, a star. Exoplanets do not orbit our sun, but are orbiting their own star.
Nothing would guarantee that any amount of exoplanets would have a moon.
The size of a planet is a defined term based on size, but it doesn't necessarily have to have a large mass to be a planet.

The value of the frequency of the wave was assumed to be 50Hz and the speed was computed to be 2410 m/s
Wave and MotionGiven Data
Wavelength = 48.2 metersFrequency f = 50 Hz (Assumed value)We know that the relationship between speed, frequency and wavelength is given as
v = fλ
Substitute our values and solving for velocity(Speed) we have
v = 50*48.2
v = 2410 m/s

Summarize what reasherchers did to improve the quality of post mining sites soil in
Answer:
The researcher centred on the potential uses of biochar, charcoal primarily used for agricultural and to improve the quality of post mining sites.
A method called mountaintop removal was used by mining firms. This means that they remove rock and mineral deposits off the top of the mountain to gain access to within the coal seams. The resulting soil is infertile and strongly acidic. The compacted soil after mine proves harder to bring seed into the soil.
The researchers try to use biochar to help reforest the soil at the post-mining site. Before it was reseeded and replanted, they got permission to add a layer of biochar to a post-mining site. the team created “planting cells” of biochar‐enhanced soil on the post‐mining site and that showed improvment in the sapling growth.
