Molly wanted to test out new NikeSpeed running shoes that claim to make her run faster than her regular Nike shoes. If she wanted to test these shoes, what would be her:
Independent variable:

Dependent Variable:

TWO controlled variables:

Control Group:

Experimental Group

Answers

Answer:

Independent variable: type of shoe

Dependent Variable: running speed

TWO controlled variables: same running distance, same runner

Control Group: running with the regular Nike shoes

Experimental Group: running with the new Nikespeed shoes.

Explanation:

According to this question, Molly wants to test her new NikeSpeed running shoes that claim to make her run faster than her regular Nike shoes.

- Independent variable is the variable of an experiment that is subjected to change or manipulation by the experimenter. In this experiment, the independent variable is the SHOES that Molly wants to test.

- Dependent variable is the measured variable that responds to the change made to the independent variable. In this case, the dependent variable is the RUNNING SPEED.

- Control variable is the variable that must be kept unchanged throughout the experiment in order not to change the experiment outcome. The control variables include; SAME RUNNING DISTANCE, SAME RUNNER (MOLLY) etc.

- Control group is the group of an experiment that does not receive the experimental treatment. In this case, it is RUNNING WITH THE REGULAR NIKE SHOES.

- Experimental group is the group that receives the experimental treatment. In this case, it is RUNNING WITH THE NEW NIKE-SPEED SHOES.

Storz (2007) describes an adaptive response to low partial pressure of oxygen in an environment at high elevation. Describe three other environmental conditions besides high elevation that might result in adaptation to hypoxia. List an organism found in each of the described environmental conditions that would be predicted to exhibit adaptive responses to low partial pressure of oxygen.

Answers

Answer:

Enhanced ventilatory abilities, enhanced percentage removal of O2 from the ventilatory stream and large gill surface areas.

Explanation:

Enhanced ventilatory abilities, enhanced percentage removal of O2 from the ventilatory stream and large gill surface areas are the three other environmental conditions besides high elevation that might result in adaptation to hypoxia. These abilities will increase the resistance to lower oxygen levels in the surrounding environment. Fish is the organism which used these types of adaptation for their survival in the surrounding of low oxygen levels.

As you are walking home from studying at the library late one evening, you get startled by a strange sound behind you. This activates your sympathetic nervous system. What affect does this change have on stroke volume? Group of answer choices Stroke volume will increase due to an increase in contractility. Stroke volume will decrease due to reduced blood pressure. Stroke volume will increase due to increased blood pressure. Stroke volume decreases due to an increase in contractility. Stroke volume will increase due to a decrease in contractility.

Answers

Answer:

Stroke volume will increase due to an increase in contractility.

Explanation:

When the individual is going through a stressful situation, the sympathetic nervous system, in conjunction with the hypothalamic-pituitary-adrenal (HPA) system, sends signals to prepares the body for stressful situations.

The body gets ready to respond to stress by increasing heart biting frequency and strength, contractibility, blood pressure, stimulating respiration and dilating respiratory tracts.

Stroke volume refers to the blood volume ejected from the ventricles as a result of the heart contraction. As said before, stressful situations increase heart bitting frequency and strength, as well as contractibility. Contractibility also influences stroke volume.

Stroke volume is determined by the difference in values of the end-diastolic volume and the end-systolic volume → SV = EDV - ESV

Contractility is one of the main factors that influence stroke volume, by affecting the end-systolic volume. It does not alter the diastolic volume. Consequently, there is an increase in stroke volume.

The central factor of systolic ejection is the myocardium sarcomere contractibility. The sarcomere´s contractile capability generates strength to become shorter after myosin heads join to the uncovered actin-binding points forming cross-bridges.

how contractile vacuole function in osmoregulation​

Answers

Answer: A contractile vacuole (CV) is an organelle, or sub-cellular structure, that is involved in osmoregulation and waste removal. ... In freshwater environments, the concentration of solutes inside the cell is higher than outside the cell. Under these conditions, water flows from the environment into the cell by osmosis. The contractile vacuole (CV) complex is an osmoregulatory organelle of free-living amoebae and protozoa, which controls the intracellular water balance by accumulating and expelling excess water out of the cell, allowing cells to survive under hypotonic stress as in pond water.

What is the correct series of steps for the movement of energy in an ecosystem?

Answers

Answer:

A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another; the levels in the food chain are producers, primary consumers, higher-level consumers, and finally decomposers.

Explanation:

Answer:

The flow of energy is always unidirectional. The energy passes from primary producers to primary consumers. From the primary consumers, the energy is passed to secondary consumers and then to tertiary consumers. Thus the energy pyramid is always upright.

The most likely explanation for the branching pattern seen in the circled region labeled X is that:
A.
environmental changes resulted in extinction
B.
speciation occurred as a result of inbreeding
C.
no speciation occurred during this time
D.
environmental changes influenced speciation

Answers

Answer:

Option B

Explanation:

As we can see in the figure,  three species of the finches in circle lie on the same main branch as three sub branches. This is an example of speciation caused by interbreeding of species which led to removal  of deleterious genes and then caused emergence of three species adaptable to the existing environmental conditions.

Hence, option B is correct

In order to perceive forms and patterns from incoming stimuli, individuals utilize____.


A. feature analysis

Answers

Group of answer choices.

A. feature analysis

B. change blindness

C. selective attention

D. inattentional blindness

Answer:

A. feature analysis

Explanation:

Stimulus can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal). Thus, all living organisms (both animals and plants) respond to changes in their environment and consequently, an appropriate response or reaction is made. Also, stimulus arising from within the organism is known as internal stimulus while those from its environment are known as the external stimulus.

In organisms, the specialized cells that detect stimulus are generally known as sensory receptors while a group of these receptors is referred to as sense organ. Therefore, the senses are necessary for behavior because stimuli must be sensed in order to respond.

Stimulus control can be defined as a phenomenon that arises when a living organism responds or behaves in the presence of a stimulus and in another way in the absence of a stimulus.

For example, opening the door of a microwave oven as soon as its timer beeps.

Example II; When your body touches a hot object, you quickly move away and feel some pain subsequently.

In order to perceive forms and patterns from incoming stimuli, individuals utilize feature analysis of the signals from the environment.

A biologist explored a remote island and discovered a new living organism. After several observations were made of the
organism, the biologist claimed that it was a vascular plant. His notes are listed below.
"I have found a new organism during my explorations. The organism was found low to the ground and is green. Based on
experiments, the organism seems to require sunlight to survive. Small, oval seeds were
found on the organism; they grew
into identical organisms when put in the soil. The organism had sharp spikes around the main body, most likely for
protection. The organism was able to absorb water from the surrounding soil. It was also observed that the organism used
specialized veins to carry water throughout its body. Based on these observations and experiments, I have determined that
this organism is a vascular plant."
Which of the following observations LEAST supports his claim?
A)
The organism is low to the ground.
B)
The organism reproduces with seeds.
The organism requires sunlight.
