Answer:
Food Storage in the Seed
Explanation:
Seeds require oxygen in order to create energy for germination and development. The embryo obtains energy by decomposing its dietary reserves. This is accomplished, as in other creatures, by a process called as aerobic respiration. —a sequence of processes in which energy is released from glucose using oxygen.
Which of the following statements about active transport is true?
Molecules move down the concentration gradient.
ATP is not required to move molecules through the membrane.
ATP is formed as molecules pass through protein channels.
It results in a higher concentration of molecules on one side of the membrane.
Answer:
It results in a higher concentration of molecules on one side of the membrane.
Explanation:
Active transport is the transport of molecules up the concentration gradient. This means that molecules are going from low density to high density. This is the opposite of natural diffusion. So, it requires ATP to move the molecules this way. Diffusion normally occurs to maintain homeostasis and an equal amount of concentration on both sides of a membrane. But, with active transport, since molecules are moving up the gradient, the opposite happens and the concentrations are unequal.
Mrs. Tuff is now insistent that Tommy sits in her lap and as she speaks to Tommy he begins to cry more and refuses to open his mouth. Mrs. Tuff continues to tell Tommy that it won't hurt and if he only opens his mouth, he will get a toy. What steps can you take now to get Tommy to cooperate?
Solution :
Tommy is a young boy and is feeling afraid to open his mouth and show it to Mrs. Tuff. Something had stuck into his mouth and he is finding it difficult to eat anything and it is paining a lot.
Mrs. Tuff is insisting tommy to sit on her lap so that she could examine him but he refuses to open his mouth and cries loudly. I told Tommy that it is for his own good and he should listen to Mrs. Tuff and open his mouth so that Mrs. Tuff could treat him. By this Tommy will get relief from his pain and he will better.
I also insisted Tommy to open his mouth as it will cause him any pain. I gave something to Tommy so he can get distracted and open his mouth. Mrs. Tuff also told him that he will get a toy if he opens his mouth.
This is how I got Tommy to cooperate with Mrs. tuff.

Some of the typical properties of cancer cells are: (1) Self-sufficient growth and proliferation, (2) Defects in intracellular control mechanisms that normally arrest or permanently stop cell division in response to stress or DNA damage, (3) Ability to escape from home tissues (invasiveness) and to survive and proliferate in foreign sites (metastatic ability), and (4) Instability of the genome. True or False
Answer:
True
Explanation:
Cancer cells are abnormal cells that divide aggressively to form solid tumors, thereby differing from normal cells. Cancer cells do not need any stimulation to multiply them, i.e., they can synthesize their own growth factors that trigger uncontrolled cell proliferation. Mutations in genes associated with the progression through the cell cycle and programmed cell death (i.e., apoptosis) are a well-known hallmark of cancer cells. The mutated genes can be either 1-tumor suppressor genes that slow down cell division and repair DNA mistakes or 2-proto-oncogenes that normally help cells grow, and whose mutations cause normal cells to become cancerous (oncogenes are mutated forms of proto-oncogenes). Cancer cells are characterized by their invasiveness and metastatic potential, i.e., their ability to spread to healthy surrounding tissues through the lymph system and/or bloodstream, where these cells proliferate and produce new tumors. Finally, genomic instability, i.e., the increased susceptibility of cells to acquire and spread mutations at the genome level, is also a hallmark of cancer cells. Genomic instability results from damage to genes that regulate cell division and tumor suppressor genes.

The following illustration shows a food web for a kelp forest off of the coast of California. What do you predict would happen to the kelp population if the sea otter population declined?
The kelp population would decrease: sea otters eat urchins, and urchins eat kelp.
The kelp population would increase: sea otters eat urchins, but not exclusively.
The kelp population would remain unchanged; sea otters do not eat the kelp.
The kelp population would remain unchanged: sea otters eat urchins, but not exclusively.
Answer:
The kelp population would decrease: sea otters eat urchins, and urchins eat kelp.
Explanation:
The diagrammatic illustration in this question is showing a food web made up of a variety of species feeding on one another. As shown in the food web, sea otters are one of the top predators that can eat a wide variety of organisms.
Sea urchins feed directly on kelp, however, the population of sea urchins can be controlled by sea otters which feed on sea urchins. Hence, if population of sea otters declined, more sea urchins will be available to feed on the kelp population, hence, will DECREASE.
Answer:The kelp population would decrease: sea otters eat urchins, and urchins eat kelp.
Because the otter population decreases the urchin population increases and therefore the demand for kelp increases and the kelp population will decrease as the population of urchins increases and it feeds on the kelp and due to the reduction in otters there is nothing controlling the urchin population

Answer:
Gene therapy to correct defective genes that cause diseases.
Explanation:
Gene therapy refers to the procedure that involves the introduction of nucleic acids (DNA or RNA) into the cells of an organism for the purpose of correcting abnormalities, such as a mutations or in other words to treat a genetic disease.Gene therapy entails bringing a normal and functional gene known as a trans-gene into a cell with altered gene. Another method can bring RNA capable of partially regulating or blocking the expression of an altered gene.The nucleic acids are introduced into the patient's cells by means of a viral vector or injected directly into the cells in the form of naked DNA.pls mark brainliest

First, there is a need to understand what the carrying capacity is as it relates to the environment:
Carrying capacity refers to the maximum number of individuals of a particular species that and environment can support based on the resources it has. The population of a species in an environment grows and oscillates around the carrying capacity of the environment.Now let us look at the graph. The population size grew from 0 and then leveled off at 2,000 with time. The leveling-off also happened without any oscillation, meaning that the maximum population size the environment can support is 2,000.
Hence, the portion on the graph that indicates the carrying capacity would be the plot where the population size is 2,000 and the time being between 12 and 18. This has been circled and labeled as 'K' in the attached image.

A tech is using the H (flagellar) antigen to serotype a suspected Salmonella species. The results of the serotyping are agglutination with one well that indicates a group of possible serotypes, not one particular serotype. Quality control passed. Why did this occur
Some Salmonella H antigens can occur in multiple strains and serotypes
An antigen (Ag) is any molecule/structure such as, for example, a molecule present on the surface of a pathogenic microorganism, that can be bound by a specific antibody and/or B-cell receptor. The Kauffmann–White classification scheme is a system that was adopted for use in 1934 in order to categorize different serotypes of the bacterial genus Salmonella, based on their somatic-surface antigens. The system is a practical (diagnostic) method based on the variation in the somatic (O) and flagellar (H) antigens present in the cell wall of Salmonella species. In this classification system, 'O' antigens are determined based on oligosaccharides which are associated with lipopolysaccharide, while the "H" antigens are distinguished by the protein content of the Salmonella flagella.Learn more about this topic here:

Over the past 60 years, many amphibian species have experienced significant population declines, and some species have become extinct. Scientists suspected that local human activities such as the destruction of wetlands, regional pollution, and deforestation were the main reasons for these losses. However, research over the past 20 years reveals significant amphibian population declines in protected areas of the world, such as nature preserves and parks. These global declines suggest widespread problems including increased ultraviolet radiation, acid rain, and disease. In Switzerland, for example, 14 of the 20 native amphibian species are threatened with extinction. Chytridiomycosis is a fungal disease first identified in 1998 as a cause of massive amphibian deaths. In some severely impacted populations, a few individuals have survived, perhaps because of some natural resistance. If these resistant individuals continue to survive and prosper, new resistant populations might emerge. This would be an example of ________.

How would the absence of gravity affect the formation of planets
Answer:
The rocks and debris would never accrete into a planet.
Explanation:
Gravity is an attraction force and dependents on the mass of the objects but in the absence of the force, the rocks and debris would not come together to form a clump. So, we can say that in the absence of gravity, the rock and debris would never accrete into a planet. So, we can say that in the absence of gravity, the rock and debris would never accrete into a planet.
