Answer: Options are not given, below are the options.

A. Stabilizing effect

B. Intraspecific competition

C. Abiotic factors

D. Interspecific competition.

The correct option is B.

It is intraspecific competition

Explanation:

It is intraspecific competition because the same species of plants are competing for limited available resources.

Intraspecific competition occur between member of the same organism where organism of the same species compete for limited available resources.

A grove of pine trees grows in a cluster around the bank of a lake is an example of intraspecific competition because the pine trees are of the same species and they compete for available limited resources.

The lac operon is a genetic system found in E. coli bacteria that consists of three structural genes - lacZ, lacY, and lacA - that encode proteins involved in lactose metabolism, as well as several regulatory regions that control their expression.

The regulatory regions of the lac operon include the promoter, operator, and CAP binding site. The promoter is a DNA sequence where RNA polymerase binds to initiate transcription of the structural genes.

The operator is a DNA sequence where a regulatory protein called the Lac repressor binds to prevent RNA polymerase from transcribing the structural genes. The CAP binding site is a DNA sequence where another regulatory protein called the catabolite activator protein (CAP) binds to enhance transcription of the structural genes.

Answer:

Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

I hope that helps determine your answer.

The product of photosynthesis are the reactants of cellular respiration.

Cellular respiration is the process by which cells convert the energy stored in food molecules into a form of energy that can be used by the cells.

This process takes place in the mitochondria of the cell and involves the oxidation of glucose (sugar) to produce ATP (adenosine triphosphate), which is the main energy source for cellular processes. Cellular respiration has several stages, including glycolysis, the citric acid cycle, and the electron transport chain, each of which contributes to the generation of ATP. The end product of cellular respiration is carbon dioxide and water.

Answer: Energy provided by ATP is used in active transport, to contract muscles, to make proteins, and in many other ways

The two main ways in which cells use the energy temporarily stored in the form of ATP is in active transport, and to make proteins.

Active transport is the movement of molecules, ions, solutes, solvents against the concentration gradient. The flow of material takes place from the region of their lower concentration to the region of their higher concentration. The transport is against the gradient and hence requires energy to proceed which is given by ATP.

ATP is required to synthesize proteins in the ribosomes of the cell through the process of translation. This is a highly energy-consuming energy and thus required large amount of ATP.

The flow of lymph is from the systemic tissues into the subclavian veins.

Lymph is a fluid that circulates through the lymphatic system, which is a network of vessels, nodes, and organs. Lymph is formed from interstitial fluid that surrounds the body's tissues. It contains waste products, pathogens, and other substances that need to be transported and filtered.

Lymphatic vessels collect the lymph from the tissues and gradually merge into larger vessels. Ultimately, the lymph is directed towards larger collecting ducts, including the thoracic duct and the right lymphatic duct. These ducts empty the lymph back into the bloodstream by connecting to the subclavian veins. The subclavian veins are located near the collarbones and receive the lymph, returning it to the bloodstream to be circulated throughout the body.

A portion of the water in the oceans and freshwater bodies like lakes and rivers evaporates during the water cycle as a result of the sun's heat. Impurities in the water are left behind as a result of evaporation.

It follows that the water entering the atmosphere is cleaner than it was on Earth. Filtration is the process of removing dissolved particles like dust, parasites, bacteria, viruses, and chemicals from the clear water on top. The filters are made of sand, gravel, and charcoal. Parasites, bacteria, viruses, and germs are killed by the addition of chlorine or chloramine during the disinfection process. To make water fit for drinking, chlorine can be added.

Plants release approximately 130 billion tons of oxygen during the process of photosynthesis. As a consequence of photosynthesis, oxygen is released by plants. However, it is estimated that plants actually emit 130 billion tonnes of oxygen annually through photosynthesis.

The biochemical process known as photosynthesis is used by plants, algae, and some bacteria to produce glucose (a form of stored energy) and oxygen from sunlight, carbon dioxide, and water. In particular, the chlorophyll, a type of green pigment found in the chloroplasts of plant cells, is where this process occurs.

Chlorophyll in plants absorbs sunlight during photosynthesis, which gives water molecules the energy to divide into hydrogen and oxygen. Using the hydrogen, glucose is created from carbon dioxide, which is subsequently used as an energy source by the plant's different cellular functions.

Answer: If plants grow in soil containing worms, then plant growth will be greater, because worms help decompose organic matter

Explanation: just did it and got it right

If plants are grown in soil containing worms, then they will develop strong and healthy because worms provide the necessary elements to the soil by degrading organic matter.

A hypothesis is a scientific conjecture, not verified, that requires corroboration. It is a possibility, but not a fact.

A hypothesis must express what is expected to occur in a perfectly comprehensive manner. There must be a logical relation between variables. It must be objective.

There are different kinds of hypotheses: descriptive, correlative, differentiative, or causative.

In this example we need to consider how the presence of the worms affect the bean plants development.

The variables are the presence of worms and the plants' development.

Explanation:

Transpiration is the evaporation of water at the surfaces of the spongy mesophyll cells in leaves, followed by loss of water vapour through the stomata . Transpiration produces a tension or 'pull' on the water in the xylem vessels by the leaves. Water molecules are cohesive so water is pulled up through the plant.

Transpiration is the outcome of the association between the xylem vessels and stomata present in the leaves.  

• The evaporation of water at the surfaces of the spongy mesophyll cells in the leaves succeeded by the loss of water vapor via the stomata is termed transpiration.  

• Transpiration generates a pull or tension on the water in the xylem vessels, and these molecules of water are cohesive so pulling up of water takes place through the plant.  

• The primary sites of transpiration are the stomates present in the leaves. This stomata comprises two guard cells, which produce a small pore on the leaves' surfaces. These guard cells monitor the closing and opening of the stomates in reaction towards different environmental stimuli, and thus, regulate the loss of water by transpiration.

The phenotypic frequency from generations 1 to 3 shows there are naturally more individuals with the dominant trait. Moreover, changes in frequency show this population does not have Hardy Weinberg equilibrium.

Phenotypic frequency refers to how common a trait is in one population. In this case, the number of individuals with a recessive vs those with a dominant trait.

From the information provided in the chart, we can see in the first three generations there is a higher number of individuals with a dominant trait, which is genetically natural, and this occurs even as the population grows.

Hardy Weinberg Equilibrium is a principle that establishes under normal conditions phenotypic frequency should be constant. This does not occur in this population because by generation 6 there is almost the same number of individuals with a dominant and a recessive trait, which shows phenotypic frequency is changing.
