C. skin receptors
D. taste receptors

Answers

Answer:

[tex]\large \boxed{\sf D. \ taste \ receptors}[/tex]

Explanation:

When activated, the receptor most likely prompting the production of saliva is the taste receptor. When food enters the mouth, the salivary glands produce the saliva upon the sensation of taste.

Answer:

Taste receptors.

Explanation:

When activated, the receptor most likely prompting the production of saliva is the taste receptor. When food enters the mouth, the salivary glands produce the saliva upon the sensation of taste. The secretion of saliva (salivation) is mediated by parasympathetic stimulation; acetylcholine is the active neurotransmitter and binds to muscarinic receptors in the glands, leading to increased salivation.

When you examine fluid that you have drawn from a blood vessel in someone's arm, you find that it is relatively high in carbon dioxide and waste products. Assuming that the fluid comes from a healthy individual, you conclude that the blood vessel from which you have drawn blood could have been ______.

Answers

Answer:

The given blank can be filled with a venule.

Explanation:

A small blood vessel in the microcirculation, which connects the capillary beds to the veins is known as the venules. Various venules combine to form a vein. The walls of a venule are formed of three layers, that is, the inner endothelium formed of squamous endothelial cells, a middle layer of elastic and muscle tissue, and an external layer formed of fibrous connective tissue.  

The size of a venule ranges from 8 to 100 micrometers in diameter and are produced when capillaries come in close association. A venule refers to a small blood vessel that permits the deoxygenated blood high in carbon dioxide and waste products to return from capillary beds to the bigger blood vessels known as veins.

At temperatures higher than the maximum growth temperature for an organism:

a. proteins are permanently denatured. membranes become too fluid for proper function.
b. hydrogen bonds within molecules are broken.
c. hydrogen bonds are broken and proteins are permanently denatured.
d. hydrogen bonds are broken, proteins are denatured, and membranes become too fluid.

Answers

Answer:

The correct answer is option d, that is, hydrogen bonds are broken, proteins are denatured, and membranes become too fluid.

Explanation:

The maximum growth temperature refers to the highest temperature at which growth can take place. Let us take an example of bacteria, it is found that each bacterial species possess a requirement of specific growth temperature, which is mainly determined by the requirement of the temperature of its enzymes. Each of the organism exhibits an optimum growth temperature, a minimum growth temperature, and a maximum growth temperature.  

When for an organism, the temperature goes more than its maximum growth than it results in the dissociation of the hydrogen bonds, denaturation of the proteins, and even the membranes become too fluid. This can even result in the death of the species. However, there are some of the organisms, which can thrive high temperatures known as thermoduric organisms, but they fail to grow effectively at such temperatures.

Independent variable: _______ Dependent variable: _______ If the amount of milk a person drinks increases, the strength of his or her bones will stay the same. Independent variable: _______ Dependent variable: _______

Answers

Complete Question:

Part A: Identifying Variables

Read the following hypotheses and identify the variables.

If the number of cigarettes smoked increases, then the risk for lung cancer increases.

Independent variable: _______

Dependent variable: _______

If the number of sharks swimming in a coastal region increases, then the number of shark attacks on humans will also increase.

Independent variable: _______

Dependent variable: _______

If the amount of milk a person drinks increases, the strength of his or her bones will stay the same.

Independent variable: _______

Dependent variable: _______

Answer/Explanation:

Dependent variables are variables that is dependent on the independent variables. That is, it is the variable that changes as the independent variable changes.

Depedent variable is the main interest if a researcher. It is the variable that is measured in a research work.

In the above given hypotheses, the dependent and independent variables are shown below:

1. "risk for lung cancer" is dependent on the "number of cigarettes smoked".

"Risk for lung cancer" => dependent variable

Number of cigarettes => independent variable

2. "number of shark attacks on humans" is dependent on "number of sharks swimming".

Dependent variable => number of shark attacks on humans

Independent variable => number of sharks swimming

3. Dependent variable => strength of bone

Independent variable => amount of milk a person drinks

Answer:

Lab: Heart Rate  

Part A: Identifying Variables

The dependent variable happens as a result of values/changes associated with the independent variable.

Independent variable: number of cigarettes smoked

Dependent variable: risk for lung cancer

Independent variable: number of sharks swimming in a coastal region

Dependent variable: number of shark attacks on humans

Independent variable: amount of milk a person drinks

Dependent variable: the strength of his or her bones

Part B: Heart Rate

Hypothesis: If I hold my breath for 30 seconds, then my heart rate will

(choose 1) increase/decrease.

Independent variable: holding my breath

Dependent variable: heart rate

Part C:

The heart rate decreases because oxygen exchange in the lungs decreases.

This depends on what you chose for heart rate in the hypothesis. If you said the heart rate decreases after holding your breath, and the results showed the heart rate decreased, then the hypothesis is supported. If you said the heart rate decreases after holding your breath, and the results showed the heart rate increased, then you refuted the hypothesis.

Heart rate can change due to an increase or decrease in activity, moving positions such as sitting and standing, and emotions.

Example: Increase in activity—jumping jacks

Hypothesis: If I do five jumping jacks, then my heart rate will increase.

Test hypothesis. You can use the average resting heart rate from the previous experiment. If you do an experiment with an increase in physical activity like jumping jacks, then your data will reflect an increase in heart rate because the body requires more energy, which requires more oxygen, increasing the overall flow of blood in the body.

Support or refute the hypothesis based on the results. The hypothesis is supported if it aligns with the observed results. The hypothesis is refuted if the results don’t match the statement based on the variables.

Testing more than one variable at a time makes it difficult to interpret the results and support or refute the hypothesis. With one variable, the results can be associated with changes to that variable. To get the most reliable data to support or refute a hypothesis, an experiment should be completed several times to see if the results show the same trends.

A. understand the viewpoint of other people.

B. realize that the term heavy describes an object one way and the term big describes it another way

C. understand that six ounces of liquid in a jar and six ounces in an elongated tube are equal.

The answer is C

Explanation:

Piaget proposed the theory of cognitive development, which talks about how human intelligence is developed. Piaget worked with Children because he believed they played a significant role in the development of cognitive intelligence. Based on his work, he proposed four stages of cognitive development viz: sensorimotor, preoperational, concrete operational and formal operational stages.

However, in the preoperational stage, Piaget described children between ages 2-7 as being in this stage of cognitive development where they are yet to comprehend mental logic. One characteristics of this stage is CONSERVATION, which is the ability to know that changing a substance's appearance doesn't change the properties of that substance. Piaget proposed that Children between the ages of 2-7 lacked this conservative characteristics.

He performed an experiment where he used two beakers with the same amount of liquid. He then emptied the contents of one of the previous beakers into a new beaker with different shape (longer). Piaget was able to notice that Children at the pre-operational stage were unable to understand that the contents of the two beakers (longer one and previous beaker) were still the same despite the beaker has been changed.

Hence, according to Piaget, a child has acquired the cognitive skill of conservation when he/she is able to understand that six ounces of liquid in a jar and six ounces in an elongated tube are equal.

In response to increased levels of aldosterone, the kidneys produce In response to increased levels of aldosterone, the kidneys produce urine with a lower concentration of sodium ions. urine with a higher concentration of sodium ions. urine with less glucose. a larger volume of urine. urine with a lower concentration of potassium ions.

Answers

Answer:

The correct answer is urine with a lower concentration of sodium ions.

Explanation:

A hormone produced in the cortex or the outer section of the adrenal glands, which are located above the kidneys is known as aldosterone. The hormone plays an essential function in regulating the blood pressure primarily by functioning on the organs like colon and kidney to enhance the reabsorption of sodium or salt into the bloodstream and to enhance the concentration of potassium excreted in the urine.  

Along with sodium, the hormone also works to reabsorb more concentration of water, which further increases the volume of blood and thus the blood pressure. Therefore, with the increase in the levels of aldosterone, the kidneys generate urine with a lower concentration of sodium ions.  

In response to increased levels of aldosterone, the kidneys produce urine with a higher concentration of sodium ions. Therefore, option B is correct.

Aldosterone is a hormone produced by the adrenal glands, specifically in the zona glomerulosa of the adrenal cortex. It plays a crucial role in regulating sodium and potassium levels in the body.

When aldosterone levels increase, such as in response to low blood sodium levels or stimulation by the hormone angiotensin II. Then, it acts on the cells of the distal convoluted tubules and collecting ducts in the kidneys.

Studies of topsoil erosion on Iowa farmland shows that as much as 50 metric tons are lost per hectare during winter and spring rains. This loss is due to the loss of millimeters of soil from across the entire surface of the fields. Which type of erosion would this be?

Answers

Answer:

The type of erosion described in the question is called Water Erosion.

Explanation:

Note that the erosion is caused by winter and spring rains.

Water Erosion can happen when raindrops disintegrate the aggregates of the topsoil. The fragments collect into the soil pores and create a coagulating action which makes it difficult for the water to penetrate the soil. The rainwater having increasingly accumulated on the surface flows off along with the topsoil.

This type of erosion can be further aggravated if:

the rainfall is very heavy;the terrain has a steep gradient thus increasing the velocity of runoffthe soil type has a lower capacity to erosion
