Law is based on the fact (here, gravitational pull) and shows the relation between the moon and the earth (tides). Thus, option B is correct.

Tides are the waves observed in seas. It is mainly due to the gravitational pull exerted by the moon on the earth. The tidal force so generated is responsible for high tide and low tide.

Tides, high or low can be predicted timely. Usually there are two high tides and two low tides observed in a day. However, during the full moon and new moon, the earth, moon and the sun align in orientation, creating a combined gravity.

This is responsible for 'spring tides' which can be considered even more higher or lower in amplitude.

Thus, tides are the natural phenomena based on the law of gravity.

The phylogenetic tree expresses the relationship between different taxa and how different homolog groups evolved. The correct option is c). the homolog has evolved more rapidly in mice.

Phylogenetic trees are graphic representations that express the evolutive process through which several groups -taxa- emerged through history.

The phylogenetic tree is composed of

All the taxa in the tree share a far common ancestor. New traits emerge through history that drives the evolution of new lineages. These traits might be either morphological or molecular.

Two taxonomic groups are more related if they have a recent common ancestor. There are fewer differences (morphological or molecular) between these two groups.

On the other hand, two lineages will be less related if their common ancestor is not a recent one and is located far away in the tree. Several differences exist between these groups because many changes occurred in the middle.

Two groups are homologous when they have a common recent ancestor, even when one of the groups evolved into new groups later in time.

In the exposed example, the frog is homologous to the group composed of chicken, human, and mouse. They share a common ancestor.

The homolog evolved into different new groups, while frogs remain the same.

The correct option is c). the homolog has evolved more rapidly in mice.

The neurotransmitter dopamine is secreted by the neurons of the basal nuclei. The degeneration of these neurons results in Parkinson disease.

Parkinson's disease is a neurodegenerative disease in which movement is affected. This happens because the nerve cells do not produce enough dopamine. Parkinson's symptoms begin gradually with tremors in the hands, arms, legs, slowness of movement with balance and coordination problems. As time goes by, these problems begin to worsen until they disable the individual from simple skills.

This disease usually appears in old age around 60 years old, it is more common in men and it is not a disease that has a cure but if there are medications that can improve the symptoms, even surgery or stimulation can be given in severe cases in the brain.

Speciation occurs when two populations become reproductively isolated from one another.

In the middle of the 20th century, Ernst Mayr gave the biological concept of species.

According to the biological concept of species, a species is defined as a group of individuals who can interbreed to produce fertile offspring.

Two groups of individuals are considered different species if they cannot interbreed to produce fertile offsprings i.e, they are reproductively isolated from one another

Generally, speciation occurs due to mutations.

Mutations are large differences that arise suddenly in a population.

These mutations keep on accumulating and due to this reason, a group of individuals become different from their species and lead to the creation of a new, different species.

Hence, speciation occurs when two populations become reproductively isolated from one another.\

Answer:

Following three statements accurately describe the blood buffering system in humans.

Explanation:

1) The first statement about the buffering blood system is that enzyme carbonic anhydrase helps the buffering system by converting carbon dioxide and water into carbonic acid, which ionizes forms bicarbonate and H+.

2)  The second statement about the H2CO3 is a conjugate acid in this situation, although HCO3- is indeed a conjugate base.

3)  The third statement about the  blood buffering mechanism is that it keeps the blood's pH level close to 7.4.

The bicarbonate ions neutralise the hydronium ions whenever an acidic material reaches the blood, creating carbonic water and acid. Obviously, blood's buffering mechanism includes carbonic acid. The removal of hydronium ions as a result prevents the blood's pH of becoming acidic.

Proteins provide the primary function of enzymes, which are catalysts that quicken practically all chemical events within cells. Although some biological reactions can be catalyzed by RNAs, proteins are responsible for the majority of them. A biological catalyst called an enzyme is usually always a protein. It accelerates a certain chemical reaction in the cell.

An enzyme will cling to (bind) one or more reactant molecules in order to catalyze a process. The substrates of the enzyme are these substances. Proteins called enzymes are made up of amino acids connected by one or more polypeptide chains. The fundamental structure of a polypeptide chain refers to this arrangement of amino acids.

Gram stain is a type of differential stain.

Differential staining is a type of staining that is used to distinguish different types of microorganisms by differentiating their characteristics or composition. Therefore, gram stain is considered a type of differential staining since it uses two types of stains to distinguish gram-positive organisms from gram-negative organisms. These stains are crystal violet and safranin stains.

In contrast to differential staining, simple staining is used just to study the features of a particular bacteria and cannot be used for distinguishing purposes.

Negative staining also cannot be used for differentiating purposes as it can just be used to analyze the morphological features of cells that cannot be stained easily.

Another factor that differentiates gram stain from other staining techniques is that it uses two stains while other techniques only use one type of stain.

The pattern of change in CO₂ concentration is new plant growth in the spring increases photosynthesis rates, which lowers CO2 concentrations; this decline continues until autumn, when leaves fall and decompose, raising CO2 concentrations.

The level of carbon dioxide within the surroundings rises and falls every 12 months as plant life, thru photosynthesis and respiration, absorbs the gas in the spring and summer season, and launches it in fall and wintry weather. Now the range of that cycle is expanding as extra carbon dioxide is emitted from burning fossil fuels and different human activities.

In spring, flora in the Northern Hemisphere starts to develop and absorb CO2 from the atmosphere, so atmospheric CO2 attention decreases as the road dives down. In fall, flora starts to decay and release their CO2 again into the ecosystem, so atmospheric CO2 attention increases the line shoots up. plants are accumulating carbon within the spring and summer while they are lively, and they're liberating carbon again to the air in the fall and winter.
