The question is incomplete, the complete question is;
The equation below shows the products formed when a solution of silver nitrate (AgNO3) reacts with a solution of sodium chloride (NaCl).
AgNO3 + NaCl → NaNO3 + AgCl
(Reactants) → (Products)
In this equation, the total mass of the reactants is
A) equal to the mass of AgCl.
B) less than the mass of AgCl.
C) equal to the total mass of the products.
D) greater than the total mass of the products.
Answer:
C) equal to the total mass of the products.
Explanation:
The law of conservation of mass states that, in a given chemical reaction, mass can neither be created nor destroyed.
The implication of that is; the mass of reactants in a given chemical reaction must also be equal to the mass of the products.
For this given reaction, the mass of reactants is equal to the mass of the products since mass is neither created nor destroyed.
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.

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.

kyphosis
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.

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).
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.

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

¿ Cuales son los sistemas que intevienen en el proceso de nutricion? ¿ Que funcion cumple cada uno de ellos en ese proceso?
Answer:
digestivo, respiratorio, circulatorio y excretor
Explanation:
El proceso de nutrición consiste en la ingesta de alimentos, los cuales son posteriormente transformados en energía y estructuras celulares que el organismo necesita para funcionar normalmente. Durante este proceso, intervienen cuatro sistemas:
- Sistema digestivo: descompone químicamente los alimentos en nutrientes. Los alimentos son sometidos a un proceso de fragmentación mecánica y digestión química. En primer lugar, los alimentos son triturados en la boca por los dientes, mezclados con saliva para formar un bolo alimenticio que llega al estómago donde los jugos gástricos los transforman en una papilla conocida como quimo. A continuación, los nutrientes llegan al intestino delgado donde son mezclados con el jugo pancreático y la bilis del hígado para ser absorbidos por la sangre. Finalmente, los compuestos que no fueron absorbidos llegan al intestino grueso donde se absorbe lo que queda de agua y lo demás es eliminado.
- Sistema respiratorio: los pulmones son los órganos encargado del proceso de respiración mediante el cual el organismo intercambia gases con el ambiente a través la sangre. De este modo el organismo obtiene oxígeno que es utilizado para oxidar los nutrientes obtenidos por el sistema digestivo.
- Sistema circulatorio: encargado de transportar nutrientes y oxígeno a las células del cuerpo y simultáneamente transportar elementos de desecho hasta los órganos del sistema excretor.
- Sistema excretor: encargado de eliminar los desechos de los alimentos. Los compuestos que no fueron digeridos en el intestino delgado llegan al intestino grueso donde se transforman en las heces las cuales son expulsadas por el ano. Por otra parte, el aparato urinario formado por los riñones y la vejiga urinaria funcionan para eliminar los desechos de la sangre a través de la orina.

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.
