Answer:uses specialized channels or carriers in the cell membrane

Explanation:

When the cell needs to move molecules from an area of low concentration to one of high concentration; it uses specialized channels or carriers in the cell membrane. This process expends' energy and is called Passive transport; Mitosis: Replication.

Explanation:

Invertase, also known as beta-fructofuranosidase, is an enzyme that catalyzes the hydrolysis of sucrose into glucose and fructose. It is a glycoside hydrolase enzyme, which means that it breaks down glycosidic bonds between carbohydrates.

The structure of invertase is complex and consists of several domains. The enzyme is typically a homodimer, which means it is made up of two identical subunits. Each subunit consists of a catalytic domain, a linker region, and a non-catalytic domain.

The catalytic domain contains the active site of the enzyme, where the hydrolysis of sucrose takes place. It consists of a beta-sandwich fold with a central cavity that accommodates the substrate. The catalytic residues are located at the bottom of the cavity, where they interact with the sucrose molecule.

The linker region connects the catalytic domain to the non-catalytic domain and is flexible, allowing for movement of the catalytic domain during the enzymatic reaction.

The non-catalytic domain is located at the C-terminus of the enzyme and is involved in substrate binding and specificity. It contains a fructose-binding domain, which helps to stabilize the fructose molecule during the hydrolysis reaction.

Overall, the structure of invertase is highly conserved across different species, with slight variations in the amino acid sequence and domain arrangement.

If the pea plant has two alleles (yy) for seed color, it would be considered homozygous recessive.

When a gene has two copies of the recessive allele for a given trait, it is said to be homozygous recessive. This indicates that neither dominant allele is present and that both copies of the gene are inherited from each parent. Both copies of the gene must be homozygous recessive for the recessive phenotype to manifest in the person. For instance, in the case of Mendelian inheritance of pea plant colour, a person will be homozygous recessive for this trait and express the recessive phenotype of yellow pea colour if they have two recessive alleles for yellow pea colour (yy). A person will express the dominant phenotype of green pea colour rather than the recessive phenotype if they have at least one dominant allele for the colour (Yy or YY).

The sides of the plastic bottles caved in because of the rapid cooling of the hot tea. When the hot tea was poured into the plastic bottles and sealed, the air inside the bottles was heated up and expanded.

However, when the bottles were placed in the refrigerator, the temperature inside the bottles rapidly decreased. As the temperature decreased, the air inside the bottles contracted, creating a partial vacuum that caused the sides of the bottles to cave in. The plastic bottles are not strong enough to withstand the pressure changes caused by the rapid temperature changes. This phenomenon is known as thermal shock and can occur when hot substances are rapidly cooled in a sealed container.

The conclusion Otto Loewi drew from these results is that: (a) transmission at synapses is a chemical event since the fluid from one frog's heart after being stimulated made the second frog's heart beat faster.

A synapse is a site at which neurons connect with other neurons or effectors, such as muscle cells or gland cells, in the nervous system. This transmission may occur through chemical or electrical signals, which are regulated by specific enzymes and receptors controlled by different hormones in the body. Chemical synapses allow for the release of neurotransmitters by the axon terminal of one neuron, which binds to the receptors of the next neuron or effector to promote or inhibit nerve impulses, muscle contraction, or gland secretion.

In contrast, electrical synapses allow for the direct flow of ions through the gap junctions between the plasma membranes of two neurons, allowing for the rapid transmission of electrical impulses without the need for neurotransmitters or receptors. Loewi, in his classic experiment in 1921, demonstrated that chemical communication occurs between neurons at synapses. The frog's hearts were used in the investigation, where he stimulated one frog's heart, and an extract of fluid from that heart was transferred to a second frog's heart.

It was observed that the second frog's heart started beating faster, showing that the chemical messenger was present in the fluid from the first frog's heart. Thus, Loewi concluded that transmission at synapses is a chemical event, which led to the concept of neurotransmitters and the characterization of acetylcholine as the first neurotransmitter.

Explanation: particles of the medium through which the sound is transported vibrate parallel to the direction that the sound wave moves.

Answer:

Magnesium was the limiting nutrient in an experiment where you have a culture of algae that is growing pretty well in its current medium.

Explanation:

Quality and quantity of nutrients, light, pH, turbulence, salinity or salt content, and temperature are the primary regulating parameters for algal growth. In an experiment where two cultures are grown separately, one with nitrogen supply and the other with magnesium supply, shows good cultural growth in the one magnesium was added. Thus, rather than nitrogen, magnesium is the limiting nutrient.

The majority of algae need at least 17 critical elements to develop. The availability of these nutrients in relation to algal demand determines the nutrient that restricts algal growth in a water body. The limiting nutrient in most water bodies is either phosphorus or nitrogen, but in other systems, trace elements like iron and molybdenum may also be a problem.

The term for a group of related taxa that are found within the same V-shaped portion of a cladogram is a clade. A clade is a group of organisms that share a common ancestor and includes all of its descendants.

Cladograms are branching diagrams that show the evolutionary relationships among organisms based on their shared characteristics. In a cladogram, each branching point represents a common ancestor, and the groups of organisms that share a common ancestor are organized into nested clades.

Clades are defined by synapomorphies, which are shared derived characteristics that are present in all members of the clade but absent in more distantly related organisms. By identifying and analyzing synapomorphies, scientists can determine the evolutionary relationships among organisms and construct cladograms that reflect their shared history.

Clades can be nested within larger clades, forming a hierarchical classification system that reflects the evolutionary relationships among all living organisms.

Dominance – One allele masks the effect of another allele. Two alleles of one gene are responsible for eggplant color, which can be purple and white

Codominance –Two alleles of one gene are responsible for eggplant color ,which can be purple and white patches, purple and white. The heterozygous phenotype has both homozygous phenotypes equally expressed.

Incomplete dominance- Two alleles of one gene are responsible for eggplant color, which can be purple, lavender and white.

Epistasis- One allele masks the effect of another allele.

Dominance occurs when one allele of a gene is completely dominant over another allele. This means that only the dominant allele's trait is expressed in the organism. For example, if a plant has one allele for purple flowers and one allele for white flowers, and the purple allele is dominant, the plant will have purple flowers.

Codominance occurs when both alleles of a gene are equally dominant and both are expressed in the organism. For example, if a cow has one allele for red hair and one allele for white hair, and both alleles are codominant, the cow will have both red and white hair.

Incomplete dominance occurs when neither allele of a gene is completely dominant over the other. This results in a blending of the two traits. For example, if a plant has one allele for red flowers and one allele for white flowers, and neither allele is dominant, the plant will have pink flowers.

Epistasis occurs when one gene affects the expression of another gene. For example, if a gene for black fur is dominant over a gene for brown fur, but another gene determines whether or not the fur will be pigmented at all, the second gene can override the first gene and result in an organism with no pigmentation (white fur).
