Some hypotheses are written as___________statements

Biology
1 answer:
Sav [38]3 years ago
4 0

Answer:

A hypothesis is a tentative statement that proposes a possible explanation to some phenomenon or event. A useful hypothesis is a testable statement, which may include a prediction. A hypothesis should not be confused with a theory.

How do changes in the atmosphere from burning fossil fuels affect plant life? Select two correct answers
german

Answer:

I'd Say A because it talks about slowing down the plants and removing stuff from the soil. Fire and smoke only cause problems for the surrounding area by blocking the sun and burning the ground, removing materials plants need for life. Then when it rains all the acidic stuff kills the ground as well.

How can you increase kinetic energy?|
Darya [45]

                                        <u>Answer and Explanation</u>

<u>__________________________________________________________</u>

According to <em>Sciencing,</em>

<h2><em>Translational Kinetic Energy </em></h2>

<em>Translational kinetic energy is the energy of motion in a straight direction -- think of it as the energy of a car driving down the street. Kinetic energy is a function of the object's mass and its velocity. More specifically, translational kinetic energy can be described as one-half times the mass times the square of the object's velocity: 1/2mv^2. </em>

<em> __________________________________________________________</em>

<h2><em>Increasing Translational Kinetic Energy </em></h2>

<em>Because the translational kinetic energy formula consists of only two variables, mass, and velocity, increasing one of those properties is the only way to increase an object's translational kinetic energy. Increases to mass and velocity, however, do not have the same impact. Because kinetic energy is proportional to the velocity squared, increases in velocity will have an exponentially greater effect on translational kinetic energy. Doubling the mass of an object will only double its kinetic energy, but doubling the velocity of the object will quadruple its velocity. </em>

<em> __________________________________________________________</em>

<h2><em>Rotational Kinetic Energy </em></h2>

<em>Rotational kinetic energy describes the energy of an object rotating around a center of gravity -- for example, a rider on a Ferris wheel. In this case, kinetic energy is still a function of mass and velocity, but the terms used are slightly different to account for the movement in a circular direction. Rotational kinetic energy applies the same equation, except the mass term is replaced by a variable known as the "moment of inertia," (I), while the velocity term is replaced by the object's "angular velocity," (w) -- 1/2Iw^2. </em>

<em> __________________________________________________________</em>

<h2><em>Increasing Rotational Kinetic Energy </em></h2>

<em>As with translational kinetic energy, increasing energy is a matter of increasing mass and velocity. The "moment of inertia" is equal to an object's mass times the square of its distance from the center of rotation, so it can be increased by either increasing the object's mass or moving it farther from the center of rotation -- simply build a bigger Ferris wheel. Alternatively, you can increase the kinetic energy by increasing the angular velocity, which means simply increasing the speed at which the object rotates around the center of rotation.</em>

The answers are;

homeostasis

metabolism

heredity

movement

cells

sensitivity

reproduction

The other characteristics of living organisms include that are not among the choices are growth, adaptation, and interactions. These are characteristics shared by all living organisms whether large or small, complex or simple. They are born by a bacteria(simplest living organism) to humans (complex organisms).

Would the light reactions be affected if there were no concentration gradient of protons across the thylakoid membrane?
mariarad [96]
Yes, If there were no concentration gradient of protons across the thylakoid membrane, the ATP synthase would not be able to convert ADP to ATP.
