Passage 1: Two or more individuals trying to use the same resource, such as food, water, shelter, space, or sunlight, is called competition. Because resources are in limited supply in the environment, the use of them by one individual or population decreases the amount available to other organisms.

Red light has the longest wavelength and the least energy, while violet light has the shortest wavelength and the most energy.
Explanation:
Yw
Answer:
RED and BLUE
Explanation:
Special pigments in chloroplasts of plant cells absorb the energy of certain wavelengths of light, causing a molecular chain reaction known as the light-dependent reactions of photosynthesis. The best wavelengths of visible light for photosynthesis fall within the blue range (425–450 nm) and red range (600–700 nm).

What natural features are important in the transfer of sand from one side of an inlet to the other:
Answers
Answer:
What causes sand to move along a beach?
Sand grains move along the shore and up and down beaches because of currents made by waves. Waves break when they reach shallow water, creating turbulence. This area is called the surf zone. When waves break, some of the force is turned into currents
The natural features that are important in the transfer of sand from one side of an inlet to the other may include weathering and erosion.
How does sand move along a beach?Sand grains move along the shore and up and down beaches because of currents made by waves. Waves break when they reach shallow water, creating turbulence. This area is called the surf zone. When waves break, some of the force is turned into currents.
Most beaches get their sand from rocks on land. Over time, rain, ice, wind, heat, cold, and even plants and animals break the rock into smaller pieces. This weathering may begin with large boulders that break into smaller rocks. Water running through cracks erodes the rock. They also prevent seawater from entering wells and ponds.
Therefore, the natural features that are important in the transfer of sand from one side of an inlet to the other may include weathering and erosion.

How does the haploid form of ulva switch to its diploid form?.
Answers
The haploid form of Ulva switches to the diploid form when gametophytes produce cells that undergo mitosis to produce gametes that fuse to form a zygote. Therefore, option D is correct.
What are gametophytes?The sexual stage in the alternation of plant generations and some algae is called a gametophyte. This stage results in gametes that go through generational alternation. It produces the zygote from which sporophytes develop and is a haploid phase.
The gametophyte stage of life is the predominant one in bryophytes. The male and female gametes are produced by the gametophyte's antheridia and archegonia, respectively. Gametangia are all of these structures put together.
Thus, the haploid form of Ulva switches to the diploid form when gametophytes produce cells that undergo mitosis to produce gametes that fuse to form a zygote. Therefore, option D is correct.

Answers
[tex]\qquad\qquad\huge\underline{{\sf Answer}}♨[/tex]
➼ The Correct choice is A
❖ Lack of responsiveness
Responsiveness isn't a biological factor that affects life, so it's not suitable according to the condition specified by question.
Among the options given, a lack of responsiveness is not considered a biological property of life. Thus, the correct option for this question is A.
What are the biological properties of life?The biological properties of life may be characterized as those properties of characteristics that are eventually required for their ideal survival and make them a unique form of organisms created over the universe.
These properties may significantly include order, sensitivity or response to the environment, reproduction, adaptation, growth and development, metabolism & regulation, homeostasis, energy processing, and evolution.
A cell is the fundamental structural and functional unit of life. So, every living organism is made of one or more cells.
Therefore, a lack of responsiveness is not considered a biological property of life. Thus, the correct option for this question is A.

is carbon moving into the living things, moving out of the living things, or both?
Carbon is moving into and out of the living things, at the same time.
Carbon is only moving into the living things; it is not moving out of them.
Carbon is only moving out of the living things, it is not moving into them.
There is no way to know for sure, with this information.
Answers
Answer:
Carbon is moving into the living things, but not out. While algae conducts photosynthesis (which produces oxygen), it does not create carbon since oxygen has no carbon molecules. Since all living things are made of carbon (which the fish is consuming), and the plant also absorbs the carbon of in the ocean to assist in photosynthesis, both are consuming carbon.

What color is reflected back to cause plants to appear green?
Answers
Answer:
Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green.
Chlorophyll absorbs light in the red (long wavelength) and the blue (short wavelength) regions of the visible light spectrum. Green light is not absorbed but reflected, making the plant appear green. Chlorophyll is found in the chloroplasts of plants.
Chlorophyll absorbs light most strongly in the blue portion of the electromagnetic spectrum, followed by the red portion. Conversely, it is a poor absorber of green and near-green portions of the spectrum, hence the green color of chlorophyll-containing tissues.
Explanation:
Have a great rest of your day
#TheWizzer
Because chlorophyll does not absorb the green wavelengths of white light, it is chlorophyll that gives plants their green color. Thus, the correct option is B.
What is Chlorophyll?Chlorophyll is a pigment that is found in all green plants as well as some other species. It is crucial for the process of photosynthesis, which transforms light energy into chemical energy.
The chlorophyll pigment is in charge of giving plants their characteristic green hue since it does not absorb the green portions of white light; as a result, the plant reflects the particular light wavelength, giving it the appearance of being green.
Since chlorophyll is a poor absorber of the green and near-green portions of the electromagnetic spectrum, tissues containing chlorophyll are green in color. Chlorophyll absorbs light most powerfully in the blue and red portions of the electromagnetic spectrum.
So, the correct option is B.

C.B.A.D.The prophase is the first part of cell division, where the chromosomes become visible in the form of paired chromatids.The telophase is the final phase of cell division in which the chromosomes move to opposite ends, and nuclei are formed. Although this most relates to option D, option D relates more to the anaphase, which we will talk about in just a moment.The metaphase is the second phase, where the chromosomes all line up at the equator, and they attach to spindle fibers.The anaphase, which is the phase after metaphase, is extremely nessescary for cell division. This is the process in when the chromatids move toward opposite poles, allowing the spindle fibers to shorten. When this happens, the cell splits in two, forming the two daughter cells.________________________________________________________

If there was less water, then there would be more competition, since now a population has to live off of a little bit of water.
