Which of the following processes causes
sinkholes to form?
A. erosion of sediment by runoff
B. deposition of sediment by a river
C. deposition of calcite by groundwater
D. erosion of limestone by groundwater

Answers

Answer 1

Answer:

A. erosion of sediment by runoff

Explanation:

The formation of sinkholes involves natural processes of erosion or gradual removal of slightly soluble bedrock (such as limestone) by percolating water, the collapse of a cave roof, or a lowering of the water table. Sinkholes often form through the process of suffosion.

Answer 2

Answer:

A sinkhole is a hole in the ground that forms when water dissolves surface rock. Often, this surface rock is limestone, which is easily eroded, or worn away, by the movement of water. ... Water collects in these collapsed sections, forming sinkholes. Sinkholes also form when the roofs of caves collapse.

is a heat pack safe for period pain ?

Answers

Answer:

I hope this hepls :)

Explanation:

Heat therapy is said to work because of its analgesic properties or its ability to bring blood to the area which can penetrate deep into the muscular tissue. However, heat therapy is also said to work because it is comforting on a psychological level. According to Lorimer Moseley “to reduce pain, we need to reduce credible evidence of danger & increase credible evidence of safety” and applying heat makes us feel safe. Why? Because the cold kills!  

Despite this, there is little evidence to show that it helps alleviate pain at certain trigger points  (small patches of acutely sensitive soft tissue) in the body and there is less evidence to show that it works for period pain. One study has claimed that heat can work for period pain however the researchers failed to differentiate if their exercise programme or the psychological effect of feeling warm eased their pain. This kind of testing means that other variables influence participants’ perception of pain and we can’t be certain if the heat therapy actually helped. What we do know is there are certainly drawbacks to this kind of treatment.

What microbial types are likely to be present in each of your fomite samples? Of these, which are most likely to grow on the nutrient agar medium used in this investigation? Which is probably not culturable under the conditions used?

Answers

Hello. You did not enter the text to which these questions refer, which makes it impossible for them to be answered. However, I will try to help you in the best possible way.

It is only possible to answer your questions in a specific way by reading the experiment, however, I can inform you that formites are objects that allow the colonization and growth of microorganisms that can be major causes of diseases. Among these microorganisms are bacteria, fungi and viruses of the most varied species. Among these microorganisms, both fungi and non-demanding bacteria can grow in a nutrient agar culture medium. This is because this is a very simple culture medium where bacteria that do not need specific nutrients can grow and where most fungi can grow too. However, it is impossible for viruses to grow in this type of culture medium or in any culture medium, since viruses only develop inside a host's organism. Bacteria known as fastidious would also not grow in this type of culture medium, since they only grow with the presence of very specific nutrients.

A particular species of lizard can range in body color from dark brown to light brown. Body color influences how well an individual lizard can hide from predators. The more similar a lizard's body color is to the soil in its environment, the less likely it is to be seen by a predator The two graphs below represent two similarly-sized populations of lizards in similar environments that have medium-brown soil. Population 1 Population 2 Number of Individuals Number of individuals darker lighter darker lighter Body Color Body Color Suppose an environmental change that causes the soil color to become much different occurs in both environments. Which of the following is true? ​

Answers

Answer:

A- Population 1 is more likely to adapt and survive than population 2 because there is more variation related to body color in population 1.

Explanation:

In order for natural selection to occur, organisms within a population must have some genetic variation. That is, organisms within a population must have some traits that are different from one another. The more genetic variation that exists in a population, the better able the population is to handle environmental changes because it is more likely that at least some individuals will survive and reproduce.

The graphs show that population 1 exhibits a greater degree of genetic variation than population 2 in terms of body color. This means that if the soil in the environments where these populations live changes, it is more likely that some of the individuals in population 1 will survive and reproduce due to having advantageous body color in the new environment. Therefore, population 1 is more likely to adapt and survive than population 2 because there is more variation related to body color in population 1.

Name and explain each lymph organ.

Answers

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.

Explanation:

Given the temperatures of the areas before storm 1 and storm 2 have the same temperature 15°C and the same amount of wind blew across the areas just before the storms ( storm1 and storm 2 ) occurred.

Hence the conditions before storm 2 that could have caused more rainfall in storm 1 can be attributed to varying atmospheric conditions like; before storm 1 occurred the air parcels were most likely more warmer hence the Rainfall was higher in storm 1 but before storm 2 the air parcels moved further and lost some energy

Elephants are not the most common species in African grasslands. And although they are large, their combine biomass is really not that big compared to some of the combined biomass of plants in those habitats. The grasslands contain scattered woody plants, but they are kept in check by the uprooting activities of the elephants. Take away the elephants, and the grasslands convert to forests or to shrublands. The newly growing forests support fewer species than the previous grasslands. What term best describes the role played by elephants in these communities

Answers

Answer:

This question lacks options, options are: a. Keystone species b. Dominant species c. Competitor species d. Omnivore species e. Mutualistic species. The correct answer is a.

Explanation:

The most connected species from a trophic point of view in an ecosystem are keystone species, since their elimination has great effects on the stability and persistence of the network. The Keystone species are those species that play a crucial role in the structure and dynamics of a certain ecosystem and that, in the event of their disappearance, would be seriously unbalanced. These species are responsible for the physical structure of the habitats of many other species, and they play an important role in the succession processes of ecosystems. Elephants play an important role in maintaining the structure and balance of ecosystems in these communities, therefore they are keystone species.

Answer:

A. Keystone species.

Explanation:

A species that has huge impact on the other in the case when there is not much abundant species. In addition to this, it would keep the other populations in the ecosystem. Moreover, if the species would be removed so this would lead in diversity loss

So according to the given situation, the role that played by  elephants in these communities is keystone species  

Which two inferences about the chipmunk population can be supported with the data gathered by the biologist?

Answers

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.

Answers

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.
