Explanation:
Absorbic Acid is used as an antioxidant and it helps the product stay fresh and look good in color. It will also add a citrus flavor and it prevents microbial growth which will not let it spoil easily
The body needs it to aid in wound healing, improve iron absorption from plant-based meals, and boost the immune system. It functions as an antioxidant to shield your cells from free radicals, which may contribute to cancer, heart disease, and other illnesses.
What role does the ascorbic acid play in the product?Fruit development and postharvest storage are significantly regulated by ascorbic acid, which also impacts fruit ripening and stress tolerance. It has been extensively investigated how plants use ascorbic acid in their metabolism.
Some people may experience negative side effects from vitamin C, including headaches, nausea, heartburn, and stomach cramps. With bigger doses comes a greater likelihood of experiencing these adverse effects.
Therefore, utilized as an antioxidant, absorbic acid keeps products fresh and attractively colored. Additionally, it will give it a citrus flavor and stop microbial growth, which will keep it from spoiling quickly.

Which is least likely to be impacted by runoff from a factory? A) river B) groundwater C) lake D) ocean
Answer:
Groundwater
Explanation:
The factories mostly need large quantities of water to carry out their production precesses, however, as well as they need natural recources for their operation, they also dispose of them and a large part of the environmental contamination is due to the release of substances emitted by these. It´s very easy for toxic waste to contaminate rivers, lakes and aceans. Groundwater on the other hand is more complicated to contaminate because it´s found in aquifers below the surface of the arth, making by these factories to reach these places; althouh not impossible.
The paranasal sinuses are lined with a membrane that creates mucus during allergies or the common cold. Presence of mucus and swelling of the membranes can cause a "sinus headache." If Regina has a cold and she feels the pain of a sinus headache inferior to her eyes, which bone is housing the affected paranasal sinus?
Answer:
The maxillary sinus, that is, the sinus located in the upper jaw, would be affected.
Explanation:
Sinusitis is a very traditional disease that is associated with headache, discomfort, and increased mucus making.
The causes can be viral or bacterial or even by some inhaled noxa, sinusitis of this type is bilateral, different from sinusitis of dental cause that are usually unilateral.
The paranasal sinuses are the sinuses that pneumatize the head, that is, they generate an internal air current in the bones to be able to heat and disinfect them from those noxas that are inhaled (that is why they are covered by a ciliated mucosa that drags the noxa to the outside and also its structure is pseostratified with mucous cells that secrete mucus enveloping the noxa).
Another function of the paranasal sinuses is to be able to alleviate the weight of the head, since the shell and the bones that remain in the head formation are very heavy, thus generating these cavities filled with air to alleviate the feeling of "heavy head" "When they become inflamed and filled with mucus, they are obliterated or with a reduced space, so the head feels heavier for some people.
The paranasal sinuses are the maxillary sinuses that are in the upper jaw, the sphenoid sinuses that are in the sphenoid, the ethmoid sinuses that are in the ethmoid and the frontal ones that are in the frontal bone that is vulgarly called as the forehead.

Which characteristic describes the whale but not its food source, the phytoplankton? The whale is heterotrophic. The whale has cell walls. The whale is unicellular. The whale is a prokaryote.
Answer:
A. The whale is heterotrophic.
Explanation:
The whale is an aquatic animal that is heterotrophic in nature. Heterotrophic means that this animal lacks the ability to manufacture its own food because it depends on plants and animals as a source of food energy. Since the Whale is dependent on phytoplankton for food, this means that it is not a producer of food and as such is heterotrophic.
Phytoplankton is a marine alga. Algaes are prokaryotes and this means that they are unicellular animals without a membrane-bound nucleus. The Cell wall is mostly a characteristic of plants. So the first option is a perfect description of the whale and not its food source which is the phytoplankton.
Answer:

Which statement best describes the relationship of photosynthesis and energy?
The process of photosynthesis is energy-storing because the process converts light energy into chemical energy,
which is stored in the bonds of glucose.
The process of photosynthesis is energy-releasing because the process converts light energy into free energy that
can be used for cell functions.
The process of photosynthesis is energy-conserving because no energy is used throughout the process of forming
glucose and oxygen molecules.
The process of photosynthesis is energy-wasting because photosynthesis is an inefficient process that depletes
the cell of energy stored in the bonds of glucose.
on Edg
Answer:
A. The process of photosynthesis is energy-storing because the process converts light energy into chemical energy
Explanation:
I would say A because photosynthesis is a process in which uses light energy to split water molecules into hydrogen and water molecules, which means light energy is converted into chemical energy. And energy is also stored in the leaf temporarily as starch.

If fossil species A is consistently recovered from geological deposits beneath layers containing fossil species B, then A is considered to be older than B. This relative dating technique is based on the principle of Group of answer choices fluorine analysis. paleomagnetism. geolayering. superposition.
Answer:
superposition
Explanation:
Dating consists of ordering geological events according to the time they occurred, which ones occurred first, and which ones occurred latterly. This dating can be done by using the superposition geological principle.
Sediments can be incrusted in horizontal layers in the ground, called stratum. Different stratum can give us information about the environment in the past. They keep information about the age and the conditions under which the sediments got deposited.
Some geological principles allow us to date, relatively, the age of different geological events in the past.
Sediment layers place in a temporal sequence, let us know that the older layers are located in an inferior position concerning the newer layers. Hence, fossil species placed in more inferior layers are supposed to be older than fossil species found in more superficial layers.

The epiglottis is a:_________.
a. muscle that moves the trachea out of line with the pharynx during swallowing.
b. flap of cartilage that flips down to cover the entry to the trachea during swallowing.
c. muscle that moves the esophagus in line with the pharynx during swallowing.
d. sphincter that closes off the entry to the trachea during swallowing.
Answer:
b. flap of cartilage that flips down to cover the entry to the trachea during swallowing
Explanation:
The function of the epiglottis is to prevent food and liquids from entering the windpipe (trachea) and the lungs. It is a flap of cartilage that stands upright when we breathe, allowing air to pass into the larynx and lungs. But while we are eating or drinking, it flips down over the opening of the trachea to prevent food and liquids from getting in there.

Answer: 1. How can a healthy lifestyle lead to a healthy heart.
The heart is one of the vital if not the most vital organ of the human body,this is because it is the heart that pumps blood into systemic circulation so that the other body organs,tissues and cells can function adequately.
Any disease or injury to the heart virtually affects all other parts of the body. Therefore a healthy and proper functioning heart is important and this can only be achieved through a healthy lifestyle.
Lifestyles such as;
- Regular exercise/physical activity which will help one to loose excess weight and maintain physical fitness because when one is overweight,fat deposits on the wall of the artery narrowing the lumen/wall, this in-turn causes blood to exert more pressure as it moves through the artery and in-turn lead to hypertension and other heart conditions.
- Stop or limit the intake of alcohol because it increases your chances of getting stroke,heart attack and hypertension through the damage of heart muscles.
- Drinking enough water; this helps the kidney to filter away waste from the body preventing the waste from building up/accumulating in the body especially the heart and as such causing heart problems.
Managing of stress very well to prevent a higher risk of heart disease.
-Eat a healthy diet and manage your blood cholesterol level to prevent damage to heart muscles and blood vessels which will in-turn lead to cardiovascular disease.(High density cholesterol HDL is the good type of cholesterol and low density cholesterol (LDC) is bad for the body.
- Regular visit to a cardiologist when one has a family history of hypertension or any other heart disease.
2. HOW IS HYPERTENSION A BLOOD RELATED DISEASE?
Hypertension is a blood related disease because hypertension is caused when the force of blood along the lumen of artery (artery wall) is higher than normal. This exerted pressure by the blood gets too intense enough to cause a heart problem or a hear disease.
When the pressure gets too intense enough to rupture the artery wall,the individual comes with a heart condition known as stroke.
Which of the following statements is false? Unselected We clear and swallow over 2 million alveolar macrophages per hour. Unselected Alveolar surfaces are usually sterile. Unselected Remarkably efficient alveolar macrophages crawl freely along the internal and external alveolar surfaces. Unselected Huge numbers of infectious microorganisms are continuously carried into the alveoli.
Answer:
Remarkably efficient alveolar macrophages crawl freely along the internal and external alveolar surfaces
Explanation:
The alveolar macrophages are present on the internal lumenal surfaces of the alveolar ducts, the alveoli, and the bronchioles.
Alveolar macrophages are phagocytes that uses several surface receptors to release many secretions, to interact with other cells and molecules.
But the alveolar macrophages are intact to the inner surface only and do not crawl freely along the internal and external alveolar surfaces.
Hence, the correct option is " C".
Active transport makes it possible for cells to:______.
a. transport out secretory products and waste material against concentration gradients.
b. take up nutrients from the environment against concentrations gradients.
c. maintain nonequilibrium intracellular concentrations of ions such as Na , K , Ca2 , and H .
d. establish an electrical potential across the membrane.
e. All of the above are correct.
Answer:
e. All of the above are correct.
Explanation:
Active transport is a type of transport in living systems in which molecules/ions/substances are moved or transported against their concentration gradient i.e. from a region where the substance is LOW to a region which it is HIGH, across a membrane. Since molecules are transported across a memembrane against their concentration gradient, an energy input in form of ATP is needed to do so.
Active transport is used in living systems to transport out secretory products and waste material against concentration gradients, take up nutrients from the environment against concentrations gradients etc. Since ions are substance moved by active transport from a low region to high region, there is an imbalance in the intracellular concentration of ions, such as Na, K etc.
Since there is no equilibrium in the concentration of ions on opposite sides of the membrane, an electric potential is formed across the membrane i.e. one part of the membrane will be more positively charged than the other.
An ecologist hypothesizes that predation by a particular owl species is the major factor controlling the population of a particular rabbit species. The first step in testing this hypothesis would be to determine
Answer:
The correct answer is - whether owl eats the rabbits.
Explanation:
A hypothesis is a proposed answer for an unexplained event that doesn't fit into the current acknowledged logical hypothesis. The essential thought of a hypothesis is that there is no pre-decided result.
The Hypothesis can be proved or disproved by scientific research that has various steps but initiailly testing the hypothesis is essential:
- Making assumptions.
- Stating the research and null hypotheses
- Selecting the sampling pattern and specifying the test statistic.
- calculating the test statistic.
-Making a decision and interpreting the results.
Thus, the first step after forming a hypothesis is to check or test the hypothesis which is null hypothesis -whether owl eats the rabbits.

A lichen is an organism that structurally appears to be a single organism. But a lichen is actually two different organisms—a fungus and green algae—living together as one organism. The fungal partner derives its nutrition from the photosynthesizing algae. How does a lichen differ in its photosynthetic activity from Elysia chlorotica, the sea slug that’s considered to be a photosynthesizing animal? A. In lichens, the fungi photosynthesize on their own, while Elysia chlorotica forms a relationship with a photosynthesizing plant. B. In lichens, the relationship with the algae lasts throughout the life cycle, but in Elysia chlorotica, the relationship occurs only during the immature juvenile stage of the slug’s life cycle. C. Lichens can photosynthesize only because of the living algal partner, while Elysia chlorotica incorporates chloroplasts from algae into its cells. D. In lichens, the association between the fungi and algae is permanent, while Elysia chlorotica associates with a photosynthesizing organism only when it requires food.
Answer:
Option C
Explanation:
Lichens can photosynthesize only because of the living algal partner, while Elysia chlorotica incorporates chloroplasts from algae into its cells.
Elysia chlorotica which is a form of sea slug feeds on a specie of the genus Vaucheria (an algae) and then retains only the chroloplasts of these algae which it uses for its own supply of energy.
The algal partner in lichens is the photosynthesizing partner. It produces food and this is its role in the relationship. The fungi are heterotrophs and cannot photosynthesize food. The fungi contribute to the relationship my absorbing mineral and water and presents it to the algae.
Answer:
Lichens can photosynthesize only because of the living algal partner, while Elysia chlorotica incorporates chloroplasts from algae into its cells.
