ALL that apply.
A)
Red light is reflected by the material.
B)
Blue light is absorbed by the material.
Red light is refracted by the material
D)
Green light is absorbed by the material
E)
Blue and green light have less energy than red light.
Answers
Answer:
A, B, and D
Explanation:
Red light is reflected by the material.
Green light is absorbed by the material.
Blue light is absorbed by the material.
According to the model, red is not absorbed, which means it is reflected. It cannot pass through nor is it absorbed. Blue light and green light do not pass through, but they are not reflected either. This is called absorption.

Explain how silent mutations affect the structure and function of the protein
Answers
Answer:
Silent mutations do not affect protein function
Explanation:
A mutation is defined as any alteration in the genetic material of a cell of a living organism. Moreover, a silent mutation refers to any mutation that does not alter the phenotype of the cell/organism (they are evolutionary neutral mutations). Silent mutations are base substitutions that do not alter the amino acid sequence of the resulting protein, and therefore these mutations do not alter protein function.

What is occurring in the diagram below?
A. Sister chromatids are separating.
B. Alleles are independently assorting.
C. Genes are replicating.
D. Segments of DNA are crossing over.
Answers
Answer:
D
Explanation:
The diagram below shows a portion of a chromosome during meiosis. Meiosis is a process of cellular division that produces haploid gametes from diploid cells. The process of meiosis involves two rounds of nuclear division.
What happens in the process of meiosis ?During the first round, homologous chromosomes pair up and exchange genetic material. This process is known as crossing over.
The diagram below shows a section of the chromosome during the first meiotic division. The chromosome is composed of two sister chromatids, which are identical copies of each other.
These sister chromatids are held together by a centromere. At this stage, the sister chromatids are in the process of separating from each other. The arrows indicate the direction of movement of the chromatids as they separate. The diagram also shows a section of the chromosome where the two sister chromatids have already separated.
This section is known as a chiasma, and it is the result of crossing over. During crossing over, segments of DNA from the two homologous chromosomes exchange places. This process creates genetic variation in the gametes, which is important for evolution.
In conclusion, the diagram shows sister chromatids separating, alleles independently assorting, segments of DNA crossing over, but not genes replicating. The correct answer is A. Sister chromatids are separating.

mantle
Explanation:
yea I'm pretty sure that's it
Answer:
The Mantle
Explanation:
The mantle is the layer located directly under the sima. It is the largest layer of the Earth, 1800 miles thick. The mantle is composed of very hot, dense rock. This layer of rock even flows like asphalt under a heavyweight. This flow is due to great temperature differences from the bottom to the top of the mantle. The movement of the mantle is the reason that the plates of the Earth move! The temperature of the mantle varies from 1600 degrees Fahrenheit at the top to about 4000 degrees Fahrenheit near the bottom!

B) the arrows from the sun to the atmosphere and from the atmosphere to space
C)the arrows from the Earth's surface to the atmosphere and from the atmosphere to the Earth's
surface
D)the arrows from the sun to the Earth's surface and from the Earth's surface to the underlying
rocks and soil
Answers
Answer:
The correct answer is - C. the arrows from the Earth's surface to the atmosphere and from the atmosphere to the Earth's surface.
Explanation:
Interaction between radiation and greenhouse gases can be demonstrated or represented by a model which shows how the radiation from different sources of the earth's surface is released in the atmosphere and how the radiation comes to the earth's surface from the atmosphere of the earth.
The radiation trapped by the greenhouse gases and more infrared radiation will be absorbed and emitted back toward Earth's surface, which affects and show more greenhouse effect.
Calculate the weight of an object of 30 kg on Earth. 2. Calculate the weight of an object of 30000 g on Earth. 3. Calculate the weight of an object of 2 kg on Earth. 4.

Calculate the weight of an object of 50 kg on the Moon (gravity of 1.6 m/s2) 8. Calculate the weight of an object of 50 kg on Mars (gravity of 3.7 m/s2)
Answers
Answer:
1. 294N
2. 294N
3. 19.6N
4. 19.6N
5. 4.9N
6. 4.9N
7. 80N
8. 185N
Explanation:
The weight of an object is the force that gravity is having over it, and we measure it in Neutowns (N), which equals Kg x m/s².
To find the weight of an object, we use the formula F= m x g.
F stands for force, m for the object's mass, and g for gravity, which is the force that attracts objects to Earth, and we measure it by the acceleration that an object has during free falling.
The Earth's gravity is 9.8 m/s²
1. We use the formula F=m x g
F= 30kg x 9.8 m/s²
F= 294 N
2. We have to convert the 30000g into kg to use the formula
30000÷1000= 30kg
30000g equals to 30Kg, so the object's mass (m) is 30Kg.
F= m X g
F= 30kg X 9.8 m/s²
F= 294 N
3. F= m X g
F= 2kg X 9.8 m/s²
F= 19.6 N
4.We have to convert the 2000g into Kg.
2000÷1000= 2Kg
The object's mass (m) is 2Kg.
F= m X g
F= 2kg X 9.8 m/s²
F= 19.6 N
5. F= m X g
F= 0.5 kg X 9.8 m/s²
F= 4.9 N
6.We have to convert 500g to Kg.
500g÷1000=0.5Kg
The object's mass (m) is 0.5 kg
F= m X g
F= 0.5 Kg X 9.8 m/s²
F= 4.9 N
7. The gravity on the moon is different from the one on Earth. In the formula, instead of 9.8 m/s² for the gravity (g), we use 1.6 m/s².
F= m X g
F= 50Kg X 1.6m/s²
F= 80N
8. The gravity (g) on Mars is 3.7 m/s², so we have to use it in the formula where it says g to find the object's weight on Mars
F= 50Kg X 3.7m/s²
F= 185 N
How are food webs used to help explain ecosystem interactions?
Answers
Food webs used to help explain ecosystem interaction as the food web shows the flow of energy from one organism to another.
What is Food web?Food webs have been defined as important conceptual tools for delineating feeding relationships among species within a community, revealing species interactions and community structure, and understanding the dynamics of energy transfer in an ecosystem.
It is defined as a graphical representation of the natural interconnection of food chains and what-eats-what in an ecological community. Food web is also called consumer-resource system.
Example of Food web is Falcon eats snake, which has eaten frog, which has eaten grasshopper, which has eaten grass. A food web shows the many different pathways where plants and animals are connected

Many years ago a scientist Group E plants that produce wrinkled peas the peas from the plants produce new plants that also produce wrinkled peas the scientist concluded that something in the para plan will be transmitted to the next generation this discovery is known as
Answers
Answer:
This discovery is known as heredity.
Explanation:
In the question above, we can see an example of heredity, which is the process where a trait is passed from an ascendant to a descendant. As seen above, the wrinkled seed is a characteristic that was passed on to a plant through its parent, the plant that gave rise to it. The characteristics passed by heredity are transmitted through the continuous transfer of genetic material, present in the DNA. Since the descendants have the DNA of their parents, it is possible that the characteristics are transmitted as the generations advance.
