The growth of two plant saplings A and B, were observed for a period of 6 months. The graph shows the linear growth of the saplings, in centimeters.

Which sapling shows the greatest amount of growth during the 6 month time period? Explain.

Answers

Answer:

Sapling B

Explanation:

Since month 2 is the first month that is a point that has an ordered pair, you would take 10/2, which is, and Sapling A has its first full ordered pair at 50,3 then you would take 10/3, which is 3.3. So 5 is greater than 3.

Answers

Answer:

4.A number line going from 30 to 34. An open circle is at 32. Everything to the left of the circle is shaded.

Explanation:

It is given that the three-fourths of the employees at a bookstore came to a staff meeting. Less than 24 employees were at the meeting.

Let the total number employees be e.

Three fourth of the total employees is e, the total number of employees at the meeting were less than 24.

e < 24

Multiply 4 both sides.

ex 4 < 24×4

3e < 96

Divide both sides by 3.

e < 32

Therefore the value of e is less than 32.

In a number line as we approach towards left the the value of integers decreases.

Since the value of e is less than 32, therefore the solution graph is from negative infinity to 32.

Since 32 is not included in the solution set, therefore there is an open circle on 32.

Thanks!

Answers

Answer:D

Explanation: got it right

The neurons are the cells that conduct electrical impulse throughout the body. The correct option is A.

What is nerve impulse?

The signal commutes along the height of a nerve fiber and results in neurotransmitter release.

Neurons are the basic units of the brain and nervous system; they are the cells that receive sensory input from the outside world and sending motor commands.

Nerves carry information along the neuron and all over the nervous system via nerve impulses.

Thus, the correct option is A.

For the study of a particular drug, Marcus proposes an experiment with a particular population. Approximately 200,000 people in the United States take this drug. He started out with a sample size of 300 people. First, he conducts research on the medical history of the people in his study. He collects the information using reliable sources. He decides to repeat the experiment using a larger sample size.

Answers

The missing part of the question is as follows:

Phrase indicates a limit to the scientific accuracy of the experiment?

Answer:

The correct answer is - a sample size of 300 people.

Explanation:

In the given research Marcus developed a drug that is already 200,000 people taking the drug, and the scientist takes sample size of only 300 people for the experiment.

The sample is very small as compared to the total population who participated in the research. A sample size of 300 people is very small compared to 200,000 people. Such a small sample size will not give the proper idea and any effective result, there would be chances to miss some aspect or effect of the drug to be missed, so, this can be the limiting factor to the experiment.

how does blood works?​

Answers

Answer:

Blood is a mixture of two components: cells and plasma. The heart pumps blood through the arteries, capillaries and veins to provide oxygen and nutrients to every cell of the body. The blood also carries away waste products.

The adult human body contains approximately 5 liters (5.3 quarts) of blood; it makes up 7 to 8 percent of a person's body weight. Approximately 2.75 to 3 liters of blood is plasma and the rest is the cellular portion.

Plasma is the liquid portion of the blood. Blood cells like red blood cells float in the plasma. Also dissolved in plasma are electrolytes, nutrients and vitamins (absorbed from the intestines or produced by the body), hormones, clotting factors, and proteins such as albumin and immunoglobulins (antibodies to fight infection). Plasma distributes the substances it contains as it circulates throughout the body.

Answers

Answer:

A

Explanation:

A. The core accretion model states that planets form when clumps of gas and dust collapse, while the gravitational instability model states that small bodies grow bigger and attract layers of gas to form planets.

What are the models of planet formation?

There are two main models of planet formation: the core accretion model and the gravitational instability model.

The core accretion model states that planets form when small particles, such as dust and gas, clump together and gradually grow into larger bodies. These bodies continue to attract more material, eventually forming a planet. This model is supported by the observed existence of small, solid bodies, known as planetesimals, in the early solar system.

The gravitational instability model, on the other hand, proposes that planets form when small bodies within a protoplanetary disk (a disk of gas and dust surrounding a young star) grow larger and become gravitationally unstable. This causes them to collapse and attract layers of gas, eventually forming a planet. This model is supported by the observation of large, gaseous planets, such as Jupiter, in the solar system.

Many factors affect rigor mortis, such as the type of clothing the person was wearing. Experts from different sciences agree that the definition of death is the end of life. Blowflies are one of the first insects to arrive at a dead body and are very useful in determining the time of death. Livor mortis refers to the color of a dead body. The only two manners of death are natural death and homicidal death. Mechanism of death describes what has occured in the body to cause death. The presence of drugs in a corpse cannot be determined by a chemical analysis of larvae found feeding on the body. In the first 12 hours, a dead body cools about 1 degree F per hour. Within minutes of a death, certain insects are attracted by the smell of the first stages of decomposition. The Body Farm is a fictional account of the work of a country coroner.

- Within minutes of a death, certain insects are attracted by the smell of the first stages of decomposition. True

- The Body Farm is a fictional account of the work of a country coroner. False

Explanation:

Death refers to the permanent cessation of the biological activities in an organism as a whole. Rigor mortis refers to a recognizable sign of death, which is caused by different changes in the muscles after death. Blowflies are insects that can be attracted by the smell of dead and decomposing bodies because they need to identify warm-moist and protein-rich sources to develop their eggs. Livor mortis is the red/blue/purple discoloration in the body skin after death. The manners of death can be divided into 1-accidental, 2-natural, 3-suicidal, 4-homicidal, and 5-undetermined. The mechanisms of death refer to the specific physiological derangements that can lead to the cessation of life (e.g., a heart attack), whose understanding can be essential to elucidate a criminal case. The presence of drugs in a dead body can be determined by an autopsy. The rate at which a dead body cooling depends on the relationship between the body temperature and environmental temperature (e.g, elevated body temperatures and cool environmental conditions are known to increase this value). A body farm can be defined as a research facility where the decomposition of dead bodies can be examined.
