Which Statement Best Describes A Cause And Its Effect During The Process Or Muscle Contraction?

Answers

Answer 1

Answer. The most appropriate statement that is explaining the effect and cause during muscle contraction is. “The release of calcium ions causes myosin and actin to attach to each other.” The activation of muscles helps in the generation of muscles that send out the signals to the neurons.

Psychologists use which of the following strategies to determine a study's replicability?
a. Internal validity
b. Repeating the study
c. Study reframing
d. Generalizing

Answers

Psychologists use the strategy of repeating the study to determine a study's replicability, option (b) is correct.

Replication involves conducting the same study again, using the same methods and procedures, to see if the findings can be reproduced. This process helps psychologists to establish the reliability and generalizability of the original study's results. Replication is crucial in science as it allows researchers to assess the consistency and robustness of the findings across different samples, settings, and conditions.

If the results of a study can be consistently replicated, it increases confidence in the reliability and validity of the findings. Replication also enables researchers to identify potential factors that may influence the results, such as sample characteristics or contextual variables, and helps to refine and validate existing theories and models, option (b) is correct.

Many closely related species of ducks have different courtship dances that are performed to solidify a pair-bond. If you were to cross individuals from each of these species what would you expect to see in the hybrid offspring if behaviors related to pair-bond formation were completely due to genetics?

Answers

Answer:

I would expect to see a new phenotype in which the new duck hybrid species would express a new mixed courtship dance with the behaviors of both parentals.  

Explanation:

The cross between both parentals, each from different species, might produce a new phenotype that exhibits both parental dances. The new dance might be considered a hybrid of the parental dances.

Genetically speaking, we can think that there is a gene codifying for the courtship behavior in one species and another gene expressing a different courtship behavior in the other species. This cross´ product would be a hybrid species that exhibits a part of both parentals´ behaviors.

what is the role of microtubules in mitosis? select all that apply. what is the role of microtubules in mitosis?select all that apply. microtubules condense the chromosomes. microtubules replicate the chromosomes. microtubules bind to individual chromosomes. microtubules form the mitotic spindle. microtubules shorten, dividing the chromosomes.

Answers

The role of microtubules in mitosis is:

- microtubules form the mitotic spindle.

- microtubules bind to individual chromosomes.

Explanation to the above given short answers are written below,

- Microtubules form the mitotic spindle: During mitosis, microtubules organize and form a structure called the mitotic spindle.

The mitotic spindle plays a crucial role in separating the duplicated chromosomes into two daughter cells during cell division.

- Microtubules bind to individual chromosomes: Microtubules attach to specific regions on the chromosomes called kinetochores.

These kinetochore microtubules exert tension on the chromosomes and are responsible for moving the chromosomes towards the poles of the cell during mitosis.

The other options provided do not accurately describe the role of microtubules in mitosis:

- Microtubules do not condense the chromosomes. Chromosome condensation is mainly mediated by proteins called condensins.

- Microtubules do not replicate the chromosomes. Chromosome replication occurs during the S phase of the cell cycle.

- Microtubules do not shorten and divide the chromosomes. Microtubules exert forces on the chromosomes to separate them, but they do not directly divide the chromosomes.

Heat is necessary for all of the following processes except for:
A.Condensation
B.Evaporation
C.Melting
D.Boiling

Answers

A.condensation

Condensation is the process by which water vapor in the air is changed into liquid water.

Heat is necessary for evaporation, melting and boiling. The correct option is A.

What is condensation?

Condensation is the transformation of water vapor into liquid. It is the inverse of evaporation, in which water turns into a vapor.

Condensation occurs in one of two ways: the air is either cooled to its dew point or becomes really filled with water vapor that it cannot retain any more water.

Condensation happens when warm air collides with cold surfaces or when your environment is overly humid.

When this moist warm air comes into contact with a cold surface, it quickly cools and releases the water, which condenses into liquid droplets on the cold surface.

In the remaining processes, i.e., evaporation, melting and boiling it is required to heat them up.

Thus, the correct option is A.

If you were able to stop the process of cellular respiration after completing electron transport but prior to chemiosmosis (the movement of hydrogen ions), you would find the pH of a mitochondrion to be at its lowest:
a. in the mitochondrial matrix.
b. on the inner membrane.
c. in the intermembrane space.
d. in the cytoplasm.
e. on the outer membrane.

Answers

The pH of a mitochondrion would be lowest in the intermembrane space if you were able to interrupt the process of cellular respiration after electron transport but before chemiosmosis (the migration of hydrogen ions). Hence (c) is the correct option.

No exchange of gases would occur. Due to a shortage of oxygen, cells, tissues, and other organs will begin to perish. Within the cells and tissues, carbon dioxide will begin to build up. By pushing protons from the mitochondrial matrix into the intermembrane space as it transports electrons, the electron transport chain creates the chemiosmotic gradient.

How is a typhoon formed?​

Answers

Answer:

A typhoon forms when winds blow into areas of the ocean where the water is warm. These winds collect moisture and rise, while colder air moves in below. This creates pressure, which causes the winds to move very quickly. The winds rotate, or spin, around a center called an eye.

Explanation:

Answer:

Compared to tropical cyclone, we have a few main requirements for typhoon development:

1. sufficiently warm sea surface temperatures,

2. Atmospheric instability,

3. High humidity in the lower to middle levels of the troposphere,

4. Enough Coriolis effect to develop a low pressure center,

5. pre-existing low level focus or disturbance, and

Should humans continue to use uranium yes or no and the reason

Answers

Answer:

Yes

Explanation:

Because uranium decays by alpha particles, external exposure to uranium is not as dangerous as exposure to other radioactive elements because the skin will block the alpha particles. Ingestion of high concentrations of uranium, however, can cause severe health effects, such as cancer of the bone or liver.

The issue is extremely complicated with many questions to be asked and addressed.

If you are to say yes then the reasonings most would give is the continued energy usage we would gain from it. How this energy could be used to reduce the strain on the environment and how cost effective nuclear energy is in comparison to anything else in the world.

If you say no then it could be for the danger it poses to humans when used for bad or the waste it generates which can not be recycled or destroyed and just has to be buried. Don’t forget it’s extensive usage in nuclear weaponry as well.
