The term for a close association between organisms of two or more species is Symbiosis. Option A. is correct.

Symbiosis is a biological relationship that benefits two different species that are in direct contact. In general, there are three main types of symbiotic relationships, each distinguished by the nature of the benefits that are provided to each species that participates. They are mutualism, commensalism, and parasitism.

Mutualism describes the close association of two or more species in which both benefit. Commensalism describes the close association of two or more species in which one species benefits and the other is neither harmed nor helped. Parasitism describes the close association of two or more species in which one species benefits while the other is harmed.

Therefore, Option A. symbiosis is correct.

Answer:

17%

Explanation:

Adenosine is not complementary to cytosine, so their percents won't be equal. You'd need to find out the percents of the purines(Adenosine and Thymine) that are there. You'd add 33 and 33 to make 66. 100-66=34. 34% is the pyrimidines in the dna. you'd divide it by two to find how much cytosine there is—leaving you with 17%.

Depolarization: This occurs when there is a rapid and temporary reversal of the electrical charge across the cell membrane of a neuron, leading to a brief increase in the membrane potential.

During depolarization, the inside of the neuron becomes more positively charged than the outside due to the influx of positively charged ions such as sodium (Na+) into the cell. This change in charge can trigger the opening of voltage-gated ion channels, leading to an action potential that propagates down the length of the neuron.

Depolarization is a crucial step in the process of neuronal communication and plays a role in various physiological processes such as muscle contraction, sensory perception, and cognitive function. Dysregulation of depolarization can lead to a variety of neurological disorders.

The endocrine system achieves a set of tasks, like maintaining blood volume, controlling blood ion concentrations, and guiding how food gets through the digestive tract.

The body's long-term endocrine reactions to lower blood pressure and volume form more red blood cells. Erythropoietin, which is issued by the kidneys and both signals and aids in the survival of already formed red blood cells, is made in the bone marrow.

The endocrine system is a highly organized mechanism that maintains the proper level of hormones and their effects. Using "feedback loops" is one technique to accomplish this. Other hormones, proteins, or neural impulses govern the release of hormones. The impact of the hormone is then felt by other organs.

Digestion is guided by the endocrine system and the brain. The sensations of hunger and fullness are handled by the brain. The release of hormones and enzymes vital for food digestion in the digestive tract is directed by the endocrine system.

The nervous system and endocrine system combine signals coming from many body systems and the environment. The endocrine system also creates effector molecules, such as hormones, that can cause the body to react appropriately in order to maintain homeostasis.

More red blood cells are formed by the body's long-term endocrine responses to lower blood pressure and volume. The bone marrow produces erythropoietin, a hormone secreted by the kidneys that both alerts and promotes the survival of already created red blood cells.

The endocrine system is a meticulously planned process that keeps hormone levels and effects in check. One method to do this is to use "feedback loops." supplementary hormones, proteins, or neural.

Answer:

d solute in the tubes changing

Explanation:

The situation that most likely would cause the liquid in Tube A to rise is water passing from the region of lower starch concentration to one of higher concentration.

From the illustration, Tube A has a higher starch concentration and, thus, lower water potential as compared to Tube B. Hence, water will spontaneously move from tube B through the dialysis membrane to Tube A by osmosis.

Osmosis is a phenomenon in which water molecules move from the region of high water concentration (high water potential) to the region of low water concentration (low water potential). It is only by doing so that the level of liquid in Tube A can rise.

The following paragraph about catabolic reaction can be completed below:

The free energy released by the exergonic reactions of exergonic is stored in exergonic. The energy released by its hydrolysis to exergonic and pi drives the exergonic reactions of exergonic, which synthesize the complex molecules.

Also, during hydrolysis in mechanical and transport work, catabolic pathways is transformed into catabolic pathways.

In these transfers and transformations, some energy is lost as heat.

All the reactions of a cell require enzymes, which ensure efficient cell function by binding substrates and catabolic pathways activation energy, thus speeding up metabolic reactions.

Catabolic reactions refers to a type of metabolism which involves the breaking down of bigger molecules into smaller molecules.

So therefore, an exergonic reaction can simply be defined as those metabolic activities which occurs in the body by releasing or giving off energy.

The statement 'all enzymes work better if other substances are also present' is true because the activity of enzymes is enhanced by substances like co-factors.

In general, many enzymes require the presence of other substances, known as cofactors or coenzymes, to function optimally. These cofactors can be inorganic ions or organic molecules that bind to the enzyme and participate in the catalytic reaction.

Cofactors can be classified into two types:

Inorganic cofactors: These include metal ions such as iron, magnesium, zinc, or copper. These ions often assist in the enzyme's catalytic activity by participating in electron transfer reactions or stabilizing reaction intermediates.

Organic cofactors (coenzymes): These are typically small organic molecules that bind to the enzyme temporarily and play a crucial role in catalysis.

Risk assessment involves evaluating potential hazards or dangers and assessing the likelihood of those hazards occurring and the potential impacts they may have.

It is a systematic approach used to identify, analyze, and evaluate risks in order to make informed decisions and take appropriate actions to mitigate or manage those risks. Risk assessment considers factors such as the nature of the hazard, exposure pathways, the population or assets at risk, and the potential consequences of the hazard.

The scenario that was described of the effect of gene u on gene h is an example of recessive epistasis of u over h.

The correct option is C.

This type of epistasis, where one gene masks the expression of another gene, is known as recessive epistasis of u over h.

The fact that pigs with wings are always homozygous at gene u (u1u1) suggests that the presence of this allele is necessary for wing development. In addition, the presence of the homozygous recessive genotype (u2u2) likely results in no wing development.

The fact that allele h4 codes for grey feathers and is dominant over allele h5, which codes for white feathers, suggests that the expression of h determines feather color in pigs with wings. Therefore, the expression of h is dependent on the presence of the u1 allele.
