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.

If two objects are two meters apart, which of these changes will increase the gravitational force between the two objects?
A. decreasing the mass of one object
B. decreasing the mass of both object
C. moving the objects to one meter apart
D. moving the objects to three meters apart
Answer:
Moving the objects to one meter apart.
Explanation:
The gravitational force between tow objects is given by -
[tex]F=G\dfrac{m_1m_2}{r^2}[/tex]
Where
G is universal gravitational constant
r is distance between masses
It can be seen that the force will increase if we increase the masses or if we decrease the distance between masses.
Here, two objects are two meters apart. If the distance is decreased, the force will increase.
Here, out of 4 options, when the objects moves to 1 meter, the gravitational force will increase. Hence, the correct option is (c).

4. The clarity of lake water is affected by the amount of phytoplankton (marine plants), soil, clay, and other solids suspended in the lake. Suppose the concentration of carbon dioxide in the atmosphere changed from 340 ppm to 380 ppm from 1980 to 2005. What effect would this have on the
occurrence of the full body plate trait? Explain your answer. Hint: Think about how carbon dioxide is related to photosynthesis. (10 points)
Answer:
The increase of Co2 in the atmosphere could speed up photosynthesis and allow plants to grow and develop faster. If the rate of photosynthesis increases, more Co2 is absorbed and more oxygen is expelled.
An increase in the plant population means better filtration of the water. If the water isn’t as polluted, natural selection will take its course and the fish may not need to pass the full body plate trait to their offspring.
The increase in the concentration of carbondioxide means that the plants
rate of photosynthesis will increase.
Carbon dioxide is required in the process of photosynthesis and its reaction
with water and solar energy forms glucose and oxygen and the effects include
The increase in concentration means more plants will undergophotosynthesis and more food will be produced.
If the polluted water doesn't cause death then natural selection will occur and the fish may not need to pass the full body plate trait to their offspring depending on the exact factors involved.Read more on https://brainly.com/question/20872107

Humans are members of the taxonomic order of primates. What scientific reasoning is used to place humans in this classification grouping?
please help me quick!!!
Cladistics refines classic taxonomy by linking organisms, based on the presence or absence of unique characteristics, into “grades.” For example, if three species share a suite of characteristics but only two of them have a particular trait that is not present in more distantly related species, those two are more closely related and would be depicted as a separate grade.
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

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.

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.
