Jena is using a drawing to show how the greenhouse effect works. She uses arrows to depict the movement of
radiation from the sun, through space, and through the Earth system.
Which arrows show how radiation interacts with the greenhouse gases?
A) the arrows from the sun to the Earth's surface and from the Earth's surface to space
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
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.

Which two inferences about the chipmunk population can be supported with the data gathered by the biologist?
Answer:
The amount of food in the area decreased, causing more chipmunks to
survive to reproductive age.
Explanation:
Hope this helps :)
Chipmunks in later generations showed greater genetic diversity than previous generations, allowing for a greater survival rate in later generations. Individual chipmunks changed their genetic makeup and became more successful in the environment. The correct options are R and S.
What is genetic diversity?Genetic diversity refers to the total number of genetic traits that make up a species' genetic composition.
It varies greatly depending on the number of species present as well as across species, and it can be linked to a species' longevity.
DNA contains all the biological information and variety required to sustain life on our planet.
Genetic variety is referred to as this. It improves a species' and population's resistance to maladies, pests, climatic changes, and other pressures.
According to the findings, Chipmunks had a higher genetic variety in later generations than in earlier generations, which allowed for a higher survival rate in later generations. Individual chipmunks altered their genetic make-up and improved their chances of survival.
Thus, the correct options are R and S.

How do the genes for a defective enzyme that results in albinism compare to the normal enzyme for synthesizing melanin?
Answer:
Albinism is a genetic condition where people don't have the usual pigment (color) in their bodies.
Explanation:
The genes for a defective enzyme results in albinism in the individual as compared to the normal enzyme for synthesizing melanin because albinism occur due to defective enzyme that is responsible for the coloration of the skin while on the other hand, melanin is produced normally in the body if the enzyme is not defective and the skin has normal pigment. Albinism is a genetic condition where people don't have the usual pigment (color) in their bodies. Albinism occurs in individuals due to absence of normal amount of melanin in the body which is a natural skin pigment.

Name and explain each lymph organ.
Explanation:
What are the organs of the immune system?
Publication Details
Our immune system is made up of both individual cells and proteins as well as entire organs and organ systems. The organs of the immune system include skin and mucous membranes, and the organs of the lymphatic system too.
Organs that function as barriers
Your skin and mucous membranes are the first line of defense against germs entering from outside the body. They act as a physical barrier with support from the following:
Antibacterial substances can kill germs right from the start. A certain enzyme found in saliva, the airways and tear fluid destroys the cell walls of bacteria.
Mucus in the bronchi helps trap many of the germs we breathe in so they can be moved out of the airways by hair-like structures called cilia.
Stomach acid stops most of the germs that enter the body in the food we eat.
Harmless bacteria on our skin and many of the mucous membranes in our body also act as part of the immune system.
In addition, the reflexes that cause us to cough and sneeze help to free our airways of germs.
Illustration: The parts of the immune system
The parts of the immune system
Lymphoid organs
The lymphatic system is composed of:
Primary lymphoid organs: These organs include the bone marrow and the thymus. They create special immune system cells called lymphocytes.
Secondary lymphoid organs: These organs include the lymph nodes, the spleen, the tonsils and certain tissue in various mucous membrane layers in the body (for instance in the bowel). It is in these organs where the cells of the immune system do their actual job of fighting off germs and foreign substances.
Bone marrow
Bone marrow is a sponge-like tissue found inside the bones. That is where most immune system cells are produced and then also multiply. These cells move to other organs and tissues through the blood. At birth, many bones contain red bone marrow, which actively creates immune system cells. Over the course of our life, more and more red bone marrow turns into fatty tissue. In adulthood, only a few of our bones still contain red bone marrow, including the ribs, breastbone and the pelvis.
Thymus
The thymus is located behind the breastbone above the heart. This gland-like organ reaches full maturity only in children, and is then slowly transformed to fatty tissue. Special types of immune system cells called thymus cell lymphocytes (T cells) mature in the thymus. Among other tasks, these cells coordinate the processes of the innate and adaptive immune systems. T cells move through the body and constantly monitor the surfaces of all cells for changes.
Lymph nodes
Lymph nodes are small bean-shaped tissues found along the lymphatic vessels. The lymph nodes act as filters. Various immune system cells trap germs in the lymph nodes and activate the creation of special antibodies in the blood. Swollen or painful lymph nodes are a sign that the immune system is active, for example to fight an infection.
Spleen
The spleen is located in the left upper abdomen, beneath the diaphragm, and is responsible for different kinds of jobs:
It stores various immune system cells. When needed, they move through the blood to other organs. Scavenger cells (phagocytes) in the spleen act as a filter for germs that get into the bloodstream.
It breaks down red blood cells (erythrocytes).
It stores and breaks down platelets (thrombocytes), which are responsible for the clotting of blood, among other things.
There is always a lot of blood flowing through the spleen tissue. At the same time this tissue is very soft. In the event of severe injury, for example in an accident, the spleen may rupture easily. Surgery is then usually necessary because otherwise there is a danger of bleeding to death. If the spleen needs to be removed completely, other immune system organs can carry out its roles.

D)
organisms began to die as the population was larger
than could be supported by the limiting factors
Answer: D.) organisms began to die as the population was larger than could be supported by the limiting factors
Explanation: i just took this assessment :)
The best explanation for the microbial population beginning to decrease after a period of time is that organisms began to die as the population was larger than could be supported by limiting factors. The correct option is D).
What is the population?Applying population ecology and population genetics to study the ecology and evolution of bacteria, archaebacteria, microscopic fungi (like yeasts), and other microscopic eukaryotes is known as microbial population biology.
The evolution of the bacterial population. Growth starts out exponential. After that, the population curve levels off, which most likely denotes the population's carrying capacity. A drop in the microbial population is then shown by the curve's downward bend. Numerous causes, both density-dependent and density-independent, can be blamed for the drop.
Therefore, the correct option is D) organisms began to die as the population was larger than could be supported by the limiting factors.

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 2000 g on Earth. 5. Calculate the weight of an object of 0.5 kg on Earth. 6. Calculate the weight of an object of 500 g on Earth. 7. 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)
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
7. Which type of mass movement occurs rapidly
when a single mass of soil and rock suddenly
slips downhill?
A. creep
B. landslide
C.mudslide
D. slump
Answer:
The most destructive type of mass movement is a landslide, which occurs when rock and soil slide quickly down a steep slope. Some landslides may contain huge masses of rock, while others may contain only a small amount of rock and soil. A mudflow is the rapid movement of a mixture of water, rock, and soil.

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.
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.
