Chlorophyll makes plants and algae appear green because it reflects the green wavelengths found in sunlight, while absorbing all other colors.
However, chlorophyll is not actually a single molecule. There are 6 different chlorophylls that have been identified. The different forms (A, B, C, D, E and F), each reflect slightly different ranges of green wavelengths. Chlorophyll A is the primary molecule responsible for photosynthesis. That means that chlorophyll A is found in every single photosynthesizing organism, from land plants to algae and cyanobacteria. The additional chlorophyll forms are accessory pigments, and are associated with different groups of plants and algae and play a role in their taxonomic confusion. These other chlorophylls still absorb sunlight, and thus assist in photosynthesis. As accessory pigments, they transfer any energy that they absorb to the primary chlorophyll A instead of directly participating in the process. Chlorophyll B is mainly found in land plants, aquatic plants and green algae. In most of these organisms, the ratio of chlorophyll A to chlorophyll B is 3:1. Due to the presence of this molecule, some organizations will group the green algae into the Plant Kingdom. Chlorophyll C is found in red algae, brown algae, and dinoflagellates. This has lead to their classification under the Kingdom Chromista. Chlorophyll D is a minor pigment found in some red algae, while the rare Chlorophyll E has been found in yellow-green algae. Chlorophyll F was recently discovered in some cyanobacteria near Australia. Each of these accessory pigments will strongly absorb different wavelengths, so their presence makes photosynthesis more efficient.

A scientist performs an experiment to see how plants respond to acid rain. He places the water plants in water of varying pH measurements. The pH levels are 2.5, 6.0, 7.0, and 9.0. Each day, he measures the health of the plants by counting the number of leaves on the plant. The plants used in this experiment typically grow in water at a neutral pH.
Why was only one variable tested in this experiment?
The scientist tested one variable to determine what caused the number of leaves to change.
It just happened that way; you can test as many variables as you want.
The scientist ran out of materials so he tested only one variable.
The scientist tested two variables.
Answer:

Which describes the two ways that energy is measured?
in convection and in temperature

in radiation and in convection
in wavelength and in temperature
Answer:
The answer is D. In wavelength and temperature
Explanation:
can I have brainiest Please
Energy is the ability to do work, and it is measured in two ways: in temperature and in wavelength. Temperature is a measure of the average kinetic energy of the molecules in a substance, and is typically measured in degrees Celsius or Kelvin.
What is Wavelength?Wavelength, which is commonly expressed in nanometers (nm), is a measurement of the separation between two adjacent points in a wave pattern.
The average kinetic energy of the molecules in a substance is measured by thermometers to determine temperature. This is accomplished by measuring a material's thermal expansion during heating or contraction during cooling.
The molecules have more kinetic energy at higher temperatures. Temperature is an important factor in convection, which is the transfer of heat energy from one place to another through the movement of fluids or gases. Wavelength is measured with spectroscopy, which is the study of the interaction of light with matter.
Spectroscopy is used to measure the wavelength of light, which is the distance between two successive points in a wave pattern. Wavelength is an important factor in radiation, which is the emission of energy in the form of electromagnetic waves. Radiation is the main way that energy is transferred from one place to another in space.

D.)People kill rattlesnakes that rattle when approached by humans, but people do not kill rattlesnakes that remain silent. The quiet snakes survive and breed.
Answer:
C
Explanation:
Natural selection is when an animal with a better trait survives and reproduces. C is the best answer.
The scenarios that are examples of natural selection are People kill rattlesnakes that rattle when approached by humans, but they do not kill rattlesnakes that remain silent, the quiet snakes survive and reproduce; this is option D.
What is the role of natural selection in the evolution process?Natural selection has numerous implications because it is the driving force behind evolution and the reproduction of individuals with advantageous traits, which leads to this natural selection process and an increase in the frequency of these traits in the population over time.
Hence, the scenarios that are examples of natural selection are People kill rattlesnakes that rattle when approached by humans, but they do not kill rattlesnakes that remain silent, the quiet snakes survive and reproduce; this is option D.

Suppose a population of crabs in a certain tidal ecosystem thrives. These male crabs have one large claw and one small claw, but variation exists in the size of the large claw. They wave the large claw to attract females to their burrow. Females are attracted to males with larger claws. Which crabs will be more likely to have more offspring in this environment?
Answer: The population having one large claw will have more offspring as compared to the ones having smaller claw.
Explanation:
A population of crabs has two types of crabs in it, one with larger claw and other with smaller claw. They will try to attract the female crab in order to mate.
The males having larger claw are more attractive to the females. Females choose to prefer larger claw over smaller claw because they will have a big burrow which will help her incubate her eggs and they are older (survivor)because the crustaceans grow majority of their life.
So, the crab with large claw is likely to have more offspring than other one.
The cover of high-elevation clouds in 2002 was
closest to which of the following?
A. 5.5 okta
B. 4.0 okta
C. 3.0 okta
D. 2.5 okta
Answer:
B. 4.0 Okta
Explanation:
Okta is a measurement of cloud elevation in metrology. NASA used this metric to identify the cloud elevation. The cloud elevation reached to 4.0 okta during the year 2002. High elevation ecosystem is vulnerable. The change in okta does not produces new substance and the elevation of cloud is changed.
High elevations clouds are located at a height of 20,000 feet. They are high above where the temperature is very low and are composed of ice crystals and appears white.
The correct answer is:
Option B. 4.0 Okta
This can be explained as:
A unit of measurement of cloud extension is called okta. The amount of cloud cover at a given place in meteorology can be defined by okta.This is widely used by the meteorology department of NASA.During 2002, the elevation of clouds reached 4.0 okta.This high value of okta can make the ecosystem vulnerable.The elevation in okta value does not affect the production of any new substance.Therefore, the value was 4.0 okta in 2002.

When Mendel’s first generation pea plants were allowed to self-pollinate, the ratio of tall (dominant) to short (recessive) plants in the second generation was
Answer:
3:1
Explanation:
Gregor Mendel, who is regarded as the Father of Genetics, worked with pea plants throughout his research. He observed the trait for height in the plants. In the gene for height in pea plants, the allele for tallness (T) is dominant over the allele for shortness (t).
Mendel's first generation pea i.e. F1 plants, which were derived by crossing tall (TT) and short (tt) parents in the P generation, were heterozygous for tallness (Tt). When these F1 plants were allowed to self pollinate i.e. Tt × Tt, the following proportion of offsprings were produced in the F2 generation:
- TT, Tt, Tt, and tt
- Tall 3 : short 1
Answer:
3:1
Explanation:
3 because the dominant is always masking the recessive
so
TT, Tt, Tt, tt
