Answer:
B.C.
Explanation:
Part A
Begin by selecting a freshwater or marine aquatic ecosystem as a model for your food web. Be specific. Choose a specific lake. Or, if you choose an ocean ecosystem, identify its geographical area and depth. Keep in mind that deep-sea organisms live in a completely different environment than surface aquatic organisms.
Next, conduct research on the following conditions in the ecosystem you chose. They influence the types of organisms that can live there.
geographical features
temperature
depth/light availability
salinity
pH
unique features that contribute to the ecosystem, such as other bodies of water that connect to it, unusual chemistry, and climate
Using the information you gathered, write a paragraph that describes conditions in the ecosystem.

D. toxic
Answer:
B. corrosive
Hope this helps!
Substances that can rust or decompose are considered as corrosive.
How rusting takes place?
Rusting is an oxidation reaction. The iron reacts with water and oxygen to form hydrated iron(III) oxide, which we see as rust
A corrosive substance is one that will damage or destroy other substances with which it comes into contact by means of a chemical reaction. it will cause rusting on iron substances.
Hence, the correct option is 'B'.

Phosphofructokinase (PFK) is an enzyme that converts fructose 6-phosphate to fructose 1,6-bisphosphate, by adding a phosphate group. This is the first committed step of the metabolic pathway of glycolysis, and thus it is very tightly regulated. AMP binds to PFK at a site distinct from the binding site for fructose 6-phosphate, and stimulates the formation of fructose 1,6-bisphosphate. ATP binds to PFK at a site distinct from the binding site for fructose 6-phosphate, and inhibits the formation of fructose 1,6-bisphosphate. There are other regulators of this enzyme as well. What is the role of AMP in this example?
A. Competitive inhibitor
B. Noncompetitive inhibitor
C. Allosteric inhibitor
D. Allosteric activator
E. Catalyst
Answer:
D. Allosteric activator
Explanation:
In an enzyme, the allosteric site is a site/motif different from the active site, (i.e., the site with catalytic activity) which is able to interact with regulatory effector molecules in order to activate or inhibit enzymatic activity by influencing the tridimensional (3D) structure of the enzyme. An allosteric activator is an effector molecule with the ability to bind to a specific enzyme at a different site than the active site, thereby modifying the shape of the enzyme and increasing the affinity of this enzyme for its substrate. Moreover, Adenosine monophosphate (AMP) is a nucleotide composed of a phosphate group, a sugar ribose, and an Adenine (A) base. This effector molecule (AMP) has shown to allosterically stimulate diverse enzymes in physiological conditions (e.g., AMP-activated protein kinase).

Explanation:
Secondary succession occurs after a disturbance such as a forest fire, where there is still some organic matter to allow new plants to grow. Both types of succession take place over long periods of time and result in the communities reaching a state of equilibrium.
Suppose you seal a house plant in a transparent glass container. What about the scenario would lead to the plant's death?
(1 point)
a lack of sugars
a lack of oxygen
a lack of light
a lack of carbon dioxide
The scenario that will lead to the death of the plant is a lack of carbondioxide.
Plants are able to produce their own food through the process of photosynthesis.
One of the inorganic requirements for photosynthesis is carbondioxide.
When a plant is sealed in a glass container there would be no access to the atmospheric carbondioxide which is absorbed into the leaf through the stomata.
This would prevent the process of photosynthesis from occurring leading to the death of the plant.
Therefore, the scenario that will lead to the death of the plant is a lack of carbondioxide.

Answer:
D. Some biologists have observed Egyptian Plovers, a type of bird, land on the open mouth of a Nile crocodile without being eaten and remove leeches stuck firmly to the crocodile's gums.
Explanation:
Mutualism is when two animals are together and they are benefitted and nobody gets harmed. In this situation, the bird and the crocodile aren't attacking each other but they are both helping each other. The bid gets a nice meal and th crocodile can get rid of those leeches. In the other situations there are teo creatures but one ends up getting eaten and that is not what mutualism is about.
2. Why is the Archaea domain located in the middle of the Bacteria domain and the Eukarya domain?
Answer:
The correct answer is - it shares some characteristics with bacteria, some to eukarya and some of its own.
Explanation:
Archaea shows similarities with both true bacteria and a unique set of characters to eukarya. Eukarya have some similarities such as methanogenesis, thymine in tRNA, and many more.
It also shows similarities to bacteria as they both are prokaryotic and have similar 70 s ribosomes, no cell organelles, and no nuclear envelope. Other than these there are many more that are unique to themself such as cell walls with poly peptidoglycan, and can live in extreme condition.
How do hormones find their target cells, and what transports them to their target cells? (50 points)
Answer:
Hormones activate target cells by diffusing through the plasma membrane of the target cells. Hormones circulate throughout the body via the blood, contacting just about all cells. The "target" cells for a particular hormone have receptors, either on the cell membrane
Explanation:
Answer:
Hormones activate target cells by diffusing through the plasma membrane of the target cells.
The glands of the endocrine system secrete hormones directly into the extracellular environment. The hormones then diffuse to the bloodstream via capillaries and are transported to the target cells through the circulatory system.

Which of the following statements best supports Mendel's Law of Segregation?
Mendel law of segregation
Answer: The answer is C, the individual alleles that make up the gene must SEGREGATE (which means separate) during gamete formation, hence the name “law of segregation”
Explanation: Hope this helps
During gamete formation, the individual alleles that comprise a gene must separate. The correct option is C.
What is law of segregation?As per Mendel's law of segregation, "during gamete formation, every gene segregates from each other so that each gamete conveys only one allele for each gene." The second law of inheritance is the law of segregation.
During gamete formation, the individual alleles that comprise a gene must separate from each other in a particular way.
Thus, the correct option is C.

Rounded back and shoulders - Kyphosis
Weak abdominal muscles and short hip flexors, cause an arch in the low back - Lordosis
Protruding abdomen - Ptosis
What is Kyphosis?Kyphosis: Kyphosis is a condition where the spine is abnormally rounded in the upper back, resulting in a hump-like appearance. This can be caused by a variety of factors, including poor posture, degenerative diseases of the spine, and osteoporosis.
Mild cases of kyphosis may not cause any symptoms, but more severe cases can result in back pain, difficulty breathing, and other complications.
Lordosis: Lordosis is a condition where the spine curves inward at the lower back, resulting in an exaggerated arch. This can be caused by weak abdominal muscles, tight hip flexors, or a variety of other factors.
In some cases, lordosis may not cause any symptoms, but it can also lead to lower back pain, difficulty standing or walking, and other complications.
Ptosis: Ptosis is a condition where a body part, such as the eyelid or breast, droops or sags. In the case of a protruding abdomen, ptosis refers to a condition where the abdominal muscles and connective tissue are weakened, causing the abdomen to bulge outward.

Chlorophyll is a green pigment in plants responsible for harnessing sunlight to help the plant produce sugars through the process of photosynthesis. If several tomato plants were to be grown under lamps producing only a single color of light, what would be the least effective choice for light color
Answer:
The correct answer is - green color light.
Explanation:
The least effective choice of color would be green color. The plants absorb all different wavelength lights of the visible light spectra but the only color that is not absorbed and reflected back is green color light.
The reflection of the green color light gives the plant its green color. The most absorbed color is violet and orange (chlorophyll a) and blue and yellow by chlorophyll b. Therefore, for the production of sugar and fruit in this tomato plant, green color light would be least effective.
Answer:
green color light
