Answer:

Animal tissues are composed of specialized cells organized in a specific manner to carry out specific functions. The structure of each tissue type is adapted to fulfill its specific role. Here are a few examples:

Explanation:

Epithelial Tissue: Epithelial tissues consist of closely packed cells that form a continuous layer covering internal and external surfaces of the body. The structure of epithelial tissues, such as having tightly joined cells and the presence of specialized cell junctions, helps provide a protective barrier, regulate the exchange of substances, and enable selective absorption and secretion.

Muscle Tissue: Muscle tissues are made up of elongated muscle cells called muscle fibers. These cells have a unique structure characterized by the presence of contractile proteins (actin and myosin) that allow them to generate force and contract. The arrangement of these proteins and the organization of muscle fibers into bundles or layers enable muscle tissues to generate movement and provide mechanical support.

Connective Tissue: Connective tissues have diverse structures depending on their specific type (e.g., loose connective tissue, dense connective tissue, cartilage, bone). Generally, connective tissues consist of cells embedded in an extracellular matrix composed of proteins, fibers, and ground substance. The structure of connective tissues allows them to provide support, connect and anchor tissues and organs, protect delicate structures, and store energy.

Nervous Tissue: Nervous tissue is made up of specialized cells called neurons that transmit electrical impulses and support cells called glial cells. Neurons have a unique structure with long extensions (axons and dendrites) that facilitate the transmission of signals. The structure of nervous tissue, including the branching of neurons and the formation of synapses, enables communication and coordination of activities within the nervous system.

Answer:

D.5

Explanation:

The degree of the polynomial 3x^5 - 6x^2 + 5x is 5, so the answer is option D.

A polynomial is a type of algebraic expression that consists of variables, coefficients, and exponents.

There can be one or more terms in a polynomial, and the degree of the polynomial is determined by the highest power of the variable present in it.

For example, the polynomial 3x^2 + 4x + 5 has a degree of 2 since the highest power of the variable (x) is 2. In the given polynomial 3x^5 - 6x^2 + 5x, the highest power of the variable is 5, which means that the degree of the polynomial is 5.

Hence, the correct answer is option D.

When a population contains two separate groups that can no longer interbreed and produce fertile offspring, then Speciation has occurred.

Speciation occurs when a population consists of two distinct groups that are unable to interbreed and produce fruitful children. Speciation is the process by which a single ancestral species splits into two or more distinct species over time.

This can occur as a result of a variety of factors, including genetic drift, natural selection, and geographic isolation. When populations become separated by a geographic barrier, such as a mountain range or body of water, they may begin to evolve separately, accumulating genetic differences over time.

Eventually, these differences may become so significant that the populations can no longer interbreed and produce fertile offspring. It's important to note that the process of speciation is a gradual one and that the formation of new species can take many generations.

Additionally, it's possible for populations to become reproductively isolated and evolve separately even in the absence of a geographic barrier, through processes such as polyploidy or hybridization.

Explanation:

All of the following paired hormones have antagonistic effects except epinephrine and norepinephrine.

The adrenal medulla contains two types of secretory cells: one that produces epinephrine (adrenaline) and another that produces norepinephrine (noradrenaline).

Epinephrine and norepinephrine cause immediate, short-term changes in response to stressors, inducing the so-called fight-or-flight response. The responses include increased heart rate, breathing rate, cardiac muscle contractions, and blood-glucose levels.

They also accelerate the breakdown of glucose in skeletal muscles and stored fats in adipose tissue, and redirect blood flow toward skeletal muscles and away from skin and viscera. The release of epinephrine and norepinephrine is stimulated by neural impulses from the sympathetic nervous system that originate from the hypothalamus.

Epinephrine and norepinephrine are often utilized as vasopressor medications to treat acute hypotensive conditions, as well as in cardiac arrest therapy algorithms. Their affinity for the alpha-1 receptor is also employed to produce regional vasoconstriction to minimize bleeding during wound closure operations. Catecholamine-releasing drugs in the form of sprays or ointments are used as nasal decongestants via the same mechanism.

So, the correct answer is epinephrine and norepinephrine.

LIFO (last-in, first-out) is an inventory accounting method that assumes that the last items purchased or produced are the first to be sold or used.

In periods of rising prices, LIFO will produce a higher cost of goods sold (COGS) than other inventory accounting methods, such as FIFO (first-in, first-out). This is because under LIFO, the most recent, and therefore most expensive inventory is assumed to be sold first, resulting in a higher COGS. This, in turn, leads to lower net income and lower taxable income, as the higher COGS reduces gross profit. This can be beneficial to a company during periods of inflation, as it can help to offset the impact of rising prices on their bottom line. However, LIFO can also result in lower inventory values on the balance sheet, which may not accurately reflect the current value of the company's inventory.

This behavior is known as brood parasitism, where a bird lays its eggs in the nest of another species, forcing that species to raise the young.

Brood parasitism occurs when a bird, known as the parasitic bird, lays its eggs in the nest of another bird species, the host bird. This behavior is observed in certain bird species, such as cuckoos and cowbirds.

It is an adaptation strategy to conserve energy and resources, as it eliminates the need for building and maintaining their own nests, and frees up time and energy for other activities, such as foraging and mating. Additionally, brood parasitism can also reduce the risks of predation and parasitism for the brood parasites, as they can lay their eggs in the nests of species with better defenses against these threats.

Answer:

Cellulose is one of the major constituents in plant cell walls and is also found in bacteria [1]••. Collagen is present in tendon, bone, cartilage, skin, cornea and many other tissues of animals.

The monomer of collagen is an amino acid whereas the monomer of cellulose is beta-glucose. The monomers in collagen are linked by peptide bonds whereas those of cellulose are beta (1,4)-glycosidic bonds. Collagen is an alpha helix polypeptide with a turn every three residues whereas cellulose is a straight chain with adjacent glucose molecules rotated 180 degrees with respect to each other. Collagen has hydrogen bonds between its chains (glycine on one chain and hydroxyproline on another strand), these hydrogen bonds account for its strength. Likewise, cellulose is a strong material because of the hydrogen bonds between the -OH and O of adjacent molecules. Collagen's macrofibre structure is that of triple helices lying parallel with covalent bonds at staggered ends of carboxyl and amino terminal, thus forming collagen fibre; in cellulose, chains of beta-glucose associate in groups to form micelles, micelles arrange in larger bundles to form microfibrils. Microfibrils combine by cross-linking of chains to form macrofibrils. Both collagen and cellulose are resistant to chemical change because of their stable macro structure

Explanation:

Glycogen is a massive glucose polymer, or a collection of numerous glucose molecules. Although this is how plants store glucose, cellulose is yet another enormous glucose polymer.

One sugar, in particular, glucose, is essential for both plants and animals, although we use them in slightly different ways.  Animals use glucose primarily for energy. When we have plenty of glucose from a carbohydrate-rich meal, like pasta, our bodies store it away for later in the form of glycogen.

Glycogen is a giant polymer of glucose, meaning it is made of many glucose molecules put together. Cellulose is another giant glucose polymer, although this is how plants store glucose.

Explanation:

The one that is not an established odorant-mediated response or capability of humans is Option A, pheromone-based sexual attraction mediated by the vomeronasal organ.

Humans do not possess a functional vomeronasal organ, which is responsible for detecting pheromones in many other animals. While there is ongoing debate about the presence and function of a vestigial vomeronasal organ in humans, there is no conclusive evidence to support its role in pheromone detection and sexual attraction in humans.

The vomeronasal organ (VNO) is a specialized sensory organ found in many animals that is responsible for detecting and processing pheromones. Pheromones are chemical signals released by individuals of the same species to communicate and elicit specific behavioral responses, such as sexual attraction or territorial marking.
