Answer:

water polarity causes cohesion that pulls other water molecules up through a plant.

Explanation:

Water for plants is essential because it constitutes one of the necessary elements so that they can generate their food through the process called photosynthesis.

In effect, plants take the hydrogen from a water molecule and discard the oxygen, providing the atmosphere with this essential gas for life.

There is 2 abrasion so I put both

Answer: An abrasion is a type of open wound that's caused by the skin rubbing against a rough surface . It may be called a scrape or a graze. When an abrasion is caused by the skin sliding across hard ground, it may be called road rash.

Answer: Abrasion can happened when the wearing away of rock by sand. Abrasion can also refer to rocks that rub against other rocks.

Answer:

an abrasion is causes by skin contact with a rough or sharp surface. when forceful contact is made (with surfaces like concrete or gravel), the skin tears away.

Answer:

If a rock has a volume of 2 cm³ and a mass of 12 gr, its density will be 6 gr/cm³.

Explanation:

Density is a parameter used in chemistry and physics, which relates the mass and volume of a solid or compound, establishing the amount of volume that occupies a given mass.

If we observe the density formula, we can see that the greater the mass, the greater the density, while the volume is inversely proportional, so the lower the volume, the greater the density. This formula is:

ρ = m/V

Therefore, according to the mass and volume of the rock

ρ = 12 grs / 2 cm³

ρ = 6 grs/cm³

Being the density of the rock equal to 6 gr/cm³.

Answer:

Tropical Easterlies is from 0-30 degrees latitude

Prevailing Westerlies is from 30-60 degrees latitude

Polar Easterlies is from 60-90 degrees latitude.

Explanation:

Areas between the Equator (0 degrees N/S) and 30 degrees N/S are referred to as low latitudes. The middle latitudes lie between 30 degrees N and 60 degrees N. The high latitudes are also located between the poles (90 degrees N/S) and 60 degrees N/S.

The polar easterlies, westerlies, and trade winds are the three main worldwide wind belts. Polar easterlies go towards 60 degrees north and south from the north and south poles, respectively.

They are extremely chilly, dry winds. Between 30 and 60 degrees north and south of the equator, the westerlies can be found.

The three wind belts that cover the entire planet are known as the “global wind belts”: the tropical easterlies (also known as the trade winds) are located close to the equator.

The polar easterlies are located at the north and south poles, and the predominant westerlies are located in the middle of the two.

Therefore, three zones or belts of latitude.

Answer:

The digestive system is where most of your food digests. It first starts in your mouth as food that is swallowed goes down to your esophagus, and then into your stomach. Your stomach acids break down those foods for nutrients, and the food particles get broken down into your small and large intestines. Your liver gives out insulin, which gets broken down to glucose, where your body uses that for energy. The rectum is where undigested food goes out as waste.

Answer: Enzyme is a special kind of protein which conducts the catalysis of the reaction and speed up the rate of the reaction.

Explanation:

The change in shape of the enzyme will distort or change the shape of the active site of the enzyme thus the enzyme will not be able to bind to the specific substrate and no enzyme substrate complex will be formed so the enzyme will become non-function and will not conduct the catalysis of the reaction. Hence, no product will be formed as no reaction will occur. The high pH and temperature will distort the shape of the enzyme and the active site of the enzyme.

Changes in pH and temperature affect enzymatic activity. Any deviation from the optimum pH level or an increase of temperature over the optimum level denaturalizes the enzyme, and loses its catalytic activity.

----------------------------------

Enzymes, like all proteins, are polypeptidic molecules. They need to get an accurate tridimensional structure to accomplish their function.

There is a limited temperature and pH level at which they lose that structure and denaturalize.

• pH changes

The most accurate configuration for the best catalytic performance depends on the charge of the lateral chains and the environmental pH.

Enzymes have ionizable chemical groups in the lateral chains of their amino acids.

Depending on the environmental pH, these groups will have a positive, negative, or neutral charge.

There is an optimum pH level at which enzymes get the best configuration to accomplish their functions.

Most enzymes are sensitive to any change in pH, which might drastically affect their activity.

So every enzyme has its optimum pH level, and any slight deviations will cause the enzyme denaturalization, hence, its activity loss.

• Temperature changes

In general, the increase in temperature accelerates chemical reactions.

For every 10ºC of temperature increase, the reaction velocity duplicates.

The optimum temperature is the range in which the enzyme expresses its highest activity rate.

⇒ When the environmental temperature is lower than the optimum, there is a slow enzymatic activity.

⇒ When the temperature exceeds the optimum point, the enzymatic activity sharply decreases. It denaturalizes the enzyme. Over this level, the reaction velocity is counteracted by the loss of the catalytic activity due to denaturalization. Enzymatic activity decreases until it completely annulates.

Answer:

10,000

Explanation:

because:

1 marsh plant= 1 DDT

a minnow = 100 DDT

if 1 minnow = 100 DDT

100 marsh plants = 100 DDT

you multiply 100 by 100

You get 10,000 as the answer.

Bioaccumulation is the accumulation of persistent substances, many times toxic substances, in the organisms' tissues. In the exposed example, if the minnow eats 100 plants, it will get 100 units of DDT.

----------------------

This problem states that

When talking about bioaccumulation we refer to a net accumulation of metals and other persistent substances in the tissues of an organism.  

Accumulation occurs during the individual's life and can be transmitted to other organisms in the trophic chain.

There are two ways in which an organism can get these substances,

So, according to the introduction, each plant has one unit of DDT.

              1 marsh plant -------------- 1 unit of DDT

We need to find out how much DDT gets one single minnow that eats 100 marsh plants in one year.

So here, we can just perform a three simple rule.

1 marsh plant -------------- 1 unit of DDT

100 marsh plants ---------X = 100 units of DDT

If the minnow eats one plant, it will get one unit. But if the minnow eats 100 plants, it will get 100 units of DDT.

Answer:

- Dilation of the pupils

- Increased heart rate (chronotropism) and the force of contraction of the heart  (inotropism), as well as blood pressure.

- Bronchodilation to facilitate the entry of air

- Vasoconstriction in organs that are not needed, such as the abdominal viscera and the kidney

-Vasodilation of muscles, heart, liver and fat tissue

- Hepatic glycogenolysis and lipolysis of adipose tissue

- Increase in blood glucose

Physical stressors; for example cold, hypoglycemia, hemorrhage, hypoxia, necrosis, burn, acute pain are  stimuli that alter the physiological state affecting homeostatic mechanisms, and initiate an adaptive response necessary for survival. For their part, psychological stressors are stimuli that threaten the  current state of the individual or provoke a state of anticipation even though they do not pose an immediate threat  to physiological conditions; need to be processed by the cerebral cortex before initiating the stress response and  they depend largely on previous experiences.

Depending on the type of physical or psychological stress, neurons in the brain stem or those in the areas of the brain are activated.  limbic system respectively, which through axonal projections affect neurons of the nucleus  paraventricular cells of the hypothalamus that synthesize CRH (corticotropin-releasing hormone). Neurons  hypophysiotropic in response to a stimulus, releases CRH to the hypothalamic-pituitary portal circulation that reaches the  adenohypophysis and controls the synthesis and release of adrenocorticotropin (ACTH) that travels through the bloodstream  exerting its feedback mechanism on the adrenal gland. Therefore, the glucocorticoids secreted by the  adrenal gland will exert their actions on peripheral tissues as part of the adaptive response to  stress.

But in addition, the hypothalamus will be in charge of decoding neuronal signals originating in other brain sites and  hormonal signals coming from the periphery. Therefore, hypothalamic neurons not only secrete their  product towards the hypothalamic-pituitary portal blood, but also have nerve projections towards other  brain regions or to nuclei located in the spinal cord (such as the nucleus of the solitary tract) and  controlling the functioning of the autonomic nervous system. Thus the coordinated response to stress includes  adrenaline secretion from the adrenal medulla in response to stimulation of the autonomic system; this hormone  it causes a state of excitement or alertness in the body allowing it to respond to the challenge.

So, the combined action of the hormones cortisol and adrenaline and the autonomic nervous system (system  sympathetic-adrenal) allows a series of vegetative activities involving various apparatus (cardiovascular,  digestive, respiratory, muscular, etc.) and the activation of various metabolic pathways (of carbohydrates and lipids  fundamentally) to provide the immediate energy demands required before the aggressor stimulus or  stress.

Explanation:

During physical exertion or emotional stress, the Sympathetic Nervous System predominates over the Parasympathetic Nervous System. The sympathetic tone favors : intense physical activity for the production of energy in a rapid and prolonged way. The fear, the confusion, the  anger also stimulate the SNS.

The flight or fight reaction is the activation of the SNS on the adrenal medulla produces the release of adrenaline and norepinephrine, which in turn produce the following effects:

- Dilation of the pupils

- Increased heart rate (chronotropism) and the force of contraction of the heart  (inotropism), as well as blood pressure.

- Bronchodilation to facilitate the entry of air

- Vasoconstriction in organs that are not needed, such as the abdominal viscera and the kidney

-Vasodilation of muscles, heart, liver and fat tissue

- Hepatic glycogenolysis and lipolysis of adipose tissue

- Increase in blood glucose

This ensures a self-defense response when perceiving danger, activating a survival instinct
