Healthy soils produce healthy crops that in turn nourish people and animals. Soils supply the essential nutrients, water, oxygen and root support that our food-producing plants need to grow and flourish. They also serve as a buffer to protect delicate plant roots from drastic fluctuations in temperature.
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).
What activities will be doing to learn or practice this knowledge or skill? Engage / Explore Ch.3 Rock Cycle Igneous Rock Sedimentary Rock Metamorphic Rock
Answer:
Research on these rocks can help you to learn this knowledge.
Explanation:
For gaining complete knowledge about rock cycle and formation of different types of rocks you have to study their environmental conditions which allow them to convert into different types of rocks such as Igneous, Sedimentary and Metamorphic Rock. Every type of rock requires a set of environmental conditions that helps in their conversion from one form to another. For example, Igneous rocks are formed from the cooling of magma that is present inside the earth. Metamorphic rocks are formed when the change occurs to igneous and sedimentary rocks whereas Sedimentary rocks are formed through the solidification of sediment.

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.

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.

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.

If all photosynthesizing organisms were removed from the planet would animals still be able to perform cellular respiration?
Answer:
No
Explanation:
This is because oxygen will not be available for breathing and energy will not be released for cellular activities because photosynthesizing organisms have chlorophyll and trap light energy ffrom sunlight , using carbondioxide and water to produce glucose and oxygen. Oxygen is the by product which is the gas that is inhaled by living organisms during respiration and also break glucose to release ATP. Therefore without these organisms, respiration will be difficult.

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.
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
