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: _______

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.

Match the following: Hypoxia. A. May be cuased by tumors, mucus, or inflammatory material.B. May be caused by left sided heart failure.C. Huge amounts of harmful free radicals cause profound CNS disturbances, coma, and death D. Is difficult to identify in dark-skinned individuals.

Answers

Answer:

it is c

Explanation:

In order to determine whether you have hypoxia, your doctor will need to check the amount of oxygen in your blood. Therefore, option (C) is correct.

What do you mean by hypoxia?

Hypoxia is low levels of oxygen in your body tissues. It causes symptoms like confusion, restlessness, difficulty breathing, rapid heart rate, and bluish skin.

Moreover, hypoxia is a state in which oxygen is not available in sufficient amounts at the tissue level to maintain adequate homeostasis; this can result from inadequate oxygen delivery to the tissues either due to low blood supply or low oxygen content in the blood (hypoxemia).

Hence, heart and lung function issues can lead to five categories of conditions that cause hypoxemia: ventilation-perfusion (V/Q) mismatch, diffusion impairment, hypoventilation, low environmental oxygen and right-to-left shunting.

What is chromosomes?Write in brief about the structure of a chromosome.must include all points with explanations

Answers

Answer:

Please find the detailed explanation below

Explanation:

A chromosome is thread-like material that carries the long strands of the genetic material (DNA), which in turn carries the gene. The chromosome is the found form of nuclear material in the nucleus.

Due to the long nature of the DNA molecule, they cannot fit into the cell. Hence, to ensure they fit, the cell wraps the DNA molecule around a set of protein called HISTONE proteins to form a NUCLEOSOME. Each nucleosome is made up of DNA coiled around a set of 8 proteins called HISTONE OCTAMER. The nucleosome structure becomes more compacted and further wound around the histone to form a CHROMATIN. This chromatin then undergoes condensation to form the visible CHROMOSOME structure.

Sex hormones or hormones of the reproductive organs are certain cells in the reproductive organs that produce hormones.

The testis produces testosterone,the male sex hormone,and the ovaries produces oestrogen and progesterone, the female sex hormones.

In a sexually mature male,testosterone influences sexual behaviour, and together with FSH,regulates sperm production in the seminiferous tubules of the testes.

Sexually matured females undergo a regular 4-week reproductive or menstrual cycle during which a mature egg is released.This cycle is regulated by oestrogen and progesterone. During pregnancy, progesterone inhibits egg production (ovulation),brings about the development of the placenta and prevents the uterus from contracting....I hope this answers your question...

Answers

Answer:

The false statement is - option D.

Explanation:

The lower value is known as diastolic number which is the pressure in the arteries when the heart takes rest in between two consecutive heart beats. Diastolic value shows the pressure of arteries when heart fills with blood.

The upper value or number is known as the systolic number, it is the pressure value of arteries of an individual during the contraction of hear. The normal blood person of a health person is range from 80/60mmhg to 120/90 mmhg, above this range is considered as high blood pressure.

Thus, the false statement is - option D.

Answers

Answer:

Fomites are inanimate objects involved in the indirect contact transmission of pathogens.

Explanation:

Fomites are inanimate objects involved in the indirect contact transmission of pathogens. These objects include a whole range of items mostly found in indoor environments. When pathogens  such as viruses and bacteria come in contact with these objects through various human and animal activities such as sneezing or coughing, use of toilets etc; these pathogens remain active on these objects and can then cause disease when others come in contact with these objects.

Common fomites in the home include toilet seats and handles, doorknobs, kitchentops, bed coverings , mobile phones, light switches as well as as toys. In offices, door handles, stairway railings as well as wring materials are common fomites. Especially concerning is the issue of disease transmission by fomites in healthcare facilities since there is constant exposure of surfaces and equipments to various pathogens.

To help prevent the spread of diseases by fomites, regular handwashing and disinfection of commonly touched surfaces is required.
