2. The temperature of the areas surrounding El Campo before Storm 1 and before Storin 2 was about
15°C. The same amount of wind was blowing toward the air parcels before both storms.
El Campo
Before Storm 1
Before Storm 2
----------
Wind 15°C
15°C
What were the conditions before Storm 2, and why did more rain fall with those conditions?
Answer:
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
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

Explanation:
Wind is caused by inequal heating. As you should have learned, things expand when they get hot and contract when they get cold. So, the high pressure hot air flows into the low pressure cold air via wind.
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
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?
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.

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?
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.
What are some indirect changes on Earth from Climate Change
(Greenhouse Emissions)?
a. Coral Bleaching
b. Ocean Acidification
c. Sea Level Rise
d. All of the above
Answer:
The answer is D.All of the above
Answer:
D
Explanation:
1: Coral Bleaching happens when 2 to 3 degree temperature changes.
2: carbon dioxide (CO2) in the atmosphere is being absorbed at the surface of the ocean at an increasing rate. This excess CO2 results in more hydrogen ions, which increases the acidity of the ocean.
3: sea level rise happens when ice caps or glaciers melt.
4: it's all of them

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.

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.

is a heat pack safe for period pain ?
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.

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.
