Answer:
Energy flows in a one-way direction i.e. unidirectional flow
Explanation:
Matter and energy both pass through an ecosystem as organisms feed on one another. However, as rightly emphasized in this question, matter in form of elements such as water, nitrogen, phosphorus etc. moves in different directions and is recycled within and between ecosystems through closed loops called biogeochemical cycles.
Contrarily to how matter is recycled in an ecosystem i.e. within and between, ENERGY only flows in one direction. Energy enters an ecosystem in form of light (sun) and is passed down from one trophic level to another starting from the producers. This unidirectional pattern of energy flow differentiates energy flow from matter recycling.

Scenario: Before the industrial revolution in England the predominant peppered moth had light colored
wings. After the industrial revolution more dark colored moths appeared until they were the dominant form of
the moth. The major predators of these moths were sparrows that relied on sight to identify and eat the
moths.
The dark colred moths began to increase in numbers in the forest of the industrial area because
A They blended in with the dark tree trunks and were camouflaged from the sparrow predators
B They were not as sensitive to the sooty pollution as the light colored moths
C The reproduction rate was slower than the light colored moths

Sohan was a very active and a social child. He used to come forward for anybody help. One day he attended a blood donation camp and was ready to donate blood, but his blood test was done and he was HIV+ve. Therefore he was very upset and lost his interest in all activities and remained absent from school for long time. Rajiv, his friend met him and counselled him.He (Sohan) was back at school. a) What sense of responsibility did Rajiv show? b) A HIV+ve person should be isolated. Do you agree with this statement. Justify your answer?
Explanation:
(a) After vis friends comforted him he went back to school.
(b) No. HIV can only be caught by another person of they come in contact with your blood or through sexual intercourse. So it is not possible for others to become infected if they didn't come in contact with the person's blood or have unprotected intercourse. There is no reason for a HIV+ve person to isolate themself from the outside world. They are people just as we are but they only have something that can cause them to be really sick.

Answer: During the process of transcription, the information stored in a gene's DNA is transferred to a similar molecule called RNA (ribonucleic acid) in the cell nucleus. ... A type of RNA called transfer RNA (tRNA) assembles the protein, one amino acid at a time.
The sequence of nucleotides of DNA directs the formation of the structure of proteins. The information stored in the DNA is transferred to the RNA by transcription and the RNA forms the proteins.
What is the process of protein formation?The process of the creation of protein molecules is called protein biosynthesis. Amino acid synthesis, transcription, translation, and post-translational events are the steps that are involved in protein synthesis. In the case of amino acid synthesis, a set of biochemical processes happen and they produce amino acids from various carbon sources like glucose.
In the case of biological systems, protein synthesis happens inside the cell. In the case of prokaryotes, it occurs in the cytoplasm. In eukaryotes, it happens in part in the nucleus and partly in the cytoplasm.
The transcript is formed in the nucleus and leaves the nucleus to reache the ribosomes and it is translated there and forms a protein molecule that has a specific sequence of amino acids.
The creation of proteins by cells uses DNA, RNA, and various enzymes. Usually, it includes the events like transcription, translation, and post-translational events. These are protein folding, modifications, and proteolysis.
Therefore, the sequence of nucleotides of DNA directs the formation of the structure of proteins. The information stored in the DNA is transferred to the RNA by transcription and the RNA forms the proteins.

Yogurt,cheese, and other foods are produced through alcoholic fermentation. True or false?
True these are both examples of food produced through alcoholic fermentation.
What is Alcoholic fermentation?
The chemical reaction that produces alcohol is known as alcoholic fermentation. In essence, beer, wine, sake, and cider all begin with yeast eating a type of sugar, which is the basis for this process.
Even hard liquors, such as your preferred tequila, begin with a straightforward alcoholic fermentation.
Alcoholic fermentation produces three primary byproducts. Alcohol, which has historically been a crucial component of beer, wine, and hard cider, is one of them, which is not surprising.
Therefore, True these are both examples of food produced through alcoholic fermentation.

i) predict which of the liquids would cause the largest decrease in mass of potato stick
PLEASE PLEASE HELP ME I HAVE 10 MINUTES ONLY, I WILL GIVE YOU THE BRAINLIEST!!
Answer:
1.0 mol per dm^3 sodium chloride solution
Explanation:
The idea behind this question is that the water inside the potato stick would move into the surrounding liquid naturally if the density outside the stick is greater than it is inside. Therefore, the liquid that would most encourage the flow of water from the potato stick would be the moet dense liquid- which in this case, is 1.0 mol per dm^3 sodium chloride solution.
describe the effect of magnesium deficiency on the transport of sucrose out of the leaves and the sucrose concentration out of the leaf
Answer:
The impact of diminishing the convergence of magnesium salt on the development of S.polyrhiza is because the low mg accessibility keeps an eye on troublesome sucrose exportation, making leaves hold sucrose three to multiple times more than the leaves of plants that get Mg in satisfactory inventory, showing that the inadequacy of this supplement causes extreme hindrance of sucrose transport.
Explanation:
The broadest areas of the plant that absorb the most sunlight are the:
1. roots
2. stems
3. leaves
Answer:
Leaves
Explanation:
Plants grow broad leaves to absorb sunlight. This is extremely helpful because this helps plants make food through photosynthesis. Roots don't absorb sunlight. They absorb water and nutrients from the soil and carry it up through the stems. The stems then transports the nutrients throughout the plant.
Equipment required: One or more buckets of water (or access to a garden hose connected to a water supply).
Pour one or two buckets of water (or run water from a garden hose) on bare ground (grass or soil is OK). Observe how the water moves. Some of the water may soak into the ground and some may flow over it. Pour a few more buckets (or run more water from the garden hose) over the same area and observe any differences in the behavior of the water. Does it still soak into the ground? Discuss how the moisture conditions in the soil will affect how much water gets absorbed. Would water be more likely to run off after the ground has been saturated by a heavy rainstorm? Discuss what happens to the water that gets absorbed into the ground.
Repeat the demonstration on a paved surface such as a driveway or sidewalk and document the differences. With no soil to absorb this water, what would happen in a heavy rainstorm? How would an engineer in charge of a city’s flood control system prepare for the runoff generated on paved parking lots and roads in a heavy rainstorm?
Answer:
No water will be soaked by the soil if it has saturated condition.
Explanation:
If the soil does not reached to its saturated point so the soil will soak the water while on the other hand, if the soil reached to its saturated point so it will not absorb the water. If soil has more water so it will not be able to absorb more water. Yes, water will be more likely to run off after the ground has been saturated by a heavy rainstorm and the water absorbed by the soil remain in the soil for the plant while the large quantity of water percolates down and reach the water table. With no soil to absorb water, the water goes to rivers and streams when a heavy rainstorm held. The engineer has to built a well drainage system in order to remove runoff water from the roads and pavement and avoid flood condition.
The Earth's tilt also causes the Sun's radiation to strike the _____ at different _____.
Answer:
hemispheres; angles
Explanation:
When a hemisphere—either northern or southern— is tilted toward the sun it has more hours of light compared to the hemisphere tilted away from the sun. Moreover, lower latitudes where the incoming solar radiation is more direct (angle closer to 90°) receive more radiation compared to higher latitudes where sunlight strikes at lower angles. The combined effect of more hours of daylight and more direct radiation in the hemisphere tilted toward the sun generates warmer temperatures compared to the hemisphere tilted away from the sun.

Do either of your diseases in part A have the same pattern of inheritance as the model colorblindness mutation you made?How do you know?
Answer:
Autosomal dominant pattern.
Explanation:
If the pattern of inheritance is same in the disease just like the model of colorblindness mutation so we can say that the disease has autosomal dominant pattern because the colorblindness mutation also occur due to the autosomal dominant pattern. Sometimes the disease is also inherited from their parents through genetically. So both diseases and the model colorblindness mutation are considered same if both have the same pattern of inheritance.

Answer:
Nutrition In Human Beings. Nutrients are the substances in food that maintain the body and make it work. Most of what one eats is made up of carbohydrates, proteins, and fats. Nutrients needed in smaller amounts, but still vital, are vitamins and minerals.
Explanation:
Hope it's answer you plz mark as Brainlist
The human being has a heterotrophic nutrition. Nutrition is realised by digestion. Digestion can be either intracellular or extracellular. Intracellular digestion occurs for example when white blood cells consume pathogens or dead tissue. Extracellular digestion occurs in the digestive tract. Digestion can be either mechanical(chewing) or chemical(hydrolysis-a process in which for every broken bond a water molecule is added).
The main types of nutrients are:
Carbohydrates that are mainly used for energy. In the digestive tract there are different enzymes that hydrolyse the carbohydrates to monosaccharides.
Carbohydrate----(enzyme)--->monosaccharide
Proteins play an important structural and functional role in the body. There are specific enzymes that digest them. They are broked down to amino acids.
Protein-------(enzyme)---->amino acid
Lipids store energy. There are enzymes that break lipids down to fatty acids and glycerol.
Lipids----(enzyme)--->fatty acids+glycerol
Vitamins help the metabolism and are not chemically processed in the digestive tract nor are minerals or water.

Margination refers to the adherence of phagocytes to microorganisms. the chemotactic response of phagocytes. adherence of phagocytes to the lining of blood vessels. dilation of blood vessels. the movement of phagocytes through walls of blood vessels.
Answer:
adherence of phagocytes to the lining of blood vessels
Explanation:
The correct answer for the medical/biological definition of margination would be the adherence of phagocytes to the lining of blood vessels.
Margination is a process that takes place when injuries occur in complex animals. During the early phase of inflammation of the injury site, the blood capillaries dilate and the white blood cells (phagocytes and leukocytes) adhere to the endothelial cells of blood vessels.
