Identify the statement that is true about Charles Darwin's theory of evolution by natural selection. Choose one: A. In each new generation, those that survive and those that don't are determined randomly. B. Organisms that are able to survive and reproduce pass on characteristics to their offspring. C. Populations of organisms continuously increase over time. D. As environments change, individual organisms choose to change to better suit the new environment.
Answer: Option B.
Organisms that are able to survive and reproduce pass on characteristics to their offspring
Explanation:
Charles Darwin theory of natural selection states that organisms possesses heritable traits that they developed and are able to survive, reproduce and adapt to their environment and they pass those traits to their generations. It is a differential survival mechanism.organisms that are able to survive and reproduce pass on the heritable characteristics to their offsprings and produce more organisms.
The statement that is true about Charles Darwin's theory of evolution by natural selection is option "B" which is Organisms that are able to survive and reproduce pass on characteristics to their offspring.
What is Charles Darwin's theory of evolution?Charles Darwin's theory of evolution is also known as darwin's theory.
It is said that evolution occurs by natural selection. Individuals in a species show divergence in physical features. This divergence is because of dissimilarities in their genes.
Thus, option "B" is Organisms that are able to survive and reproduce pass on characteristics to their offspring.

I don't really know your question but I will tell you what can be predicted.
But how can a technological forecast be made to contain probability dimensions in the same way other forecasts do? Most people think of a technology as a quite specific physical entity. They do not conceive of this entity as having the variable characteristics which would permit range forecasts or probability statements. To their minds, a precisely defined technology either will exist in a given situation, or it will not. And the forecaster must predict this exact event or else he is wrong. This misconception—which would place an impossible demand on any forecaster causes much of the confusion in discussions about technological forecasting.

Answer:
The nature of the indicated covalent bond is polar.
Explanation:
The given diagram is the Lewis structure of Methylamine which has the formula, CH₃NH₂.
In order to know that it is polar, we will discover that in the Lewis structure there are unpaired electrons in the central atom. Also, the bond that exists between the hydrogen and nitrogen shows that it is polar.
CH₃NH₂ is seen to have two charged ends that are opposite and the bonds that exists between hydrogen and nitrogen, which makes it a polar molecule.
The electronegativities of carbon, hydrogen and nitrogen can also be used to determine its polarity.

Which process do all organisms do when performing cellular respiration?
Answer:
Glycolysis
Explanation:
Glycolysis is the first step of cellular respiration, where glucose is turned into 2 pyruvate molecules.
This step happens in all living organisms, since it does not require oxygen and also occurs in the cytoplasm, which all cells have.
So, glycolysis is the process that all organisms do during cellular respiration.

Phycobiliproteins are complex proteins in cyanobacteria that absorb light energy. There are three kinds of phycobiliprotein molecules used to pass light to chlorophyll: phycoerythrin—responsible for capturing green light, phycocyanin—responsible for capturing orange-red light, and allophycocyanin—responsible for capturing red light.
Since light can only penetrate to certain depths in oceans (figure 1), phycobiliproteins capture the light available and pass it through various pathways of phycobiliproteins until the emitted light is red, which is absorbed by chlorophyll. (4 points)
A. Explain the relationship between chlorophyll absorption and wavelength.
B. In addition to the pigments commonly associated with photosynthesis, a certain photosynthetic species contains two additional pigment types. Which of the following best justifies the claim that this species is better adapted to environmental changes than the cyanobacteria described above?
Answer:
Part A:
— Chlorophyll absorbs different wavelengths than chlorophyll does.
— Chlorophyll does not absorb wavelengths that are green and yellow, which is indicated by a very low degree of the light absorption.
Part B:
Photosynthetic Organisms are organisms capable of photosynthesis. Photosynthesis is greenery and other organisms using the energy from sunlight to synthesize foods from carbon dioxide and water. Leaving allophycocyanin to be the protein these plants and other organisms receive from the light. So for the process, in order for the plants to live they must be able to go through photosynthesis giving the plants the energy and proteins they need to produce food and to release oxygen into the environment.
Answer:
The visible spectrum is the only part of the electromagnetic spectrum that can be seen by the human eye. It includes electromagnetic radiation whose wavelength is between about 400 nm and 700 nm.
Visible light from the sun appears white, but it’s actually made up of multiple wavelengths (colors) of light. You can see these different colors when white light passes through a prism: because the different wavelengths of light are bent at different angles as they pass through the prism, they spread out and form what we see as a rainbow. Red light has the longest wavelength and the least energy, while violet light has the shortest wavelength and the most energy.
Photosynthesis, the sun’s energy is converted to chemical energy by photosynthetic organisms. However, the various wavelengths in sunlight are not all used equally in photosynthesis. Instead, photosynthetic organisms contain light-absorbing molecules called pigments that absorb only specific wavelengths of visible light, while reflecting others.
The set of wavelengths absorbed by a pigment is its absorption spectrum. The set of wavelengths that a pigment doesn't absorb are reflected, and the reflected light is what we see as color. For instance, plants appear green to us because they contain many chlorophyll a and b molecules, which reflect green light.
Although both chlorophyll a and chlorophyll b absorb light, chlorophyll a plays a unique and crucial role in converting light energy to chemical energy (as you can explore in the light-dependent reactions article).
All photosynthetic plants, algae, and cyanobacteria contain chlorophyll a, whereas only plants and green algae contain chlorophyll b, along with a few types of cyanobacteria Because of the central role of chlorophyll a in photosynthesis, all pigments used in addition to chlorophyll a are known as accessory pigments—including other chlorophylls, as well as other classes of pigments like the carotenoids. The use of accessory pigments allows a broader range of wavelengths to be absorbed, and thus, more energy to be captured from sunlight.

plants preapare their good in their food in their root
Answer:
In the presence of light, chlorophyll (a substance that gives the leaves a green color) releases oxygen and produces carbohydrates, which enable the plant to grow. This complex process is called photosynthesis.
Explanation:
The roots are used to take dissolved mineral elements from the soil. The root is not capable of absorbing even the smallest organic or solid element. This means that it is important that the soil contains a certain amount of water, but also microorganisms, which have the task of decomposing organic matter and releasing the mineral elements from which it is composed.
