A group of animals that share a particular set of characteristics and forms an assemblage is called a taxon

A taxon is a collection of one or more populations of an organism or populations of organisms that taxonomists consider to be a single entity. A taxon is typically known by a specific name and assigned a certain ranking, even though neither is necessary, especially if and when it is approved or becomes established. Taxonomists frequently disagree over what constitutes a taxon and the standards for inclusion, though. If a taxon is awarded a formal scientific name, one of the nomenclature codes that indicate which scientific name is appropriate for which grouping will subsequently dictate how it should be used.

Answer:

polysaccharide

Explanation:

The most important structural component of plant cell walls is cellulose. Cellulose is a carbohydrate found in the cell wall of plants. The carbohydrate is a polysaccharide structure. Polysaccharide is made up of a long chain of several sugar units bonded together by chemical linkage. Polysaccharides examples are chitin, glycogen, cellulose, and starch. On average, a dry plant comprises 40 to 50 percent cellulose.

Answer:

No its the first one

Explanation:

Asexual reproduction allows for a population to boom in a short period of time, since there only needs one organism. That being said its important to note that the offspring will be a clone of the parent, so the genetic diversity is low. However the advantage is that the population grows really fast, think of bacteria. Most reproduce asexually, and bacteria growth is very fast given the right conditions.

Marfan syndrome is related to an autosomal dominant condition.

There are several organs constructed of elastic fibres. Skin, skeletons, and joints are the most frequent organs. Marfan syndrome will show as the chest form, long as well as thin bones (arms, legs, fingers), stretch marks inside the skin, or eye lens.

Marfan syndrome, the genetic illness, affects connective tissue, or even the fibres that hold and attach the organs and other body parts. Marfan syndrome most usually affects the skeleton, blood vessels, heart, and vision. It occurs since the normal growth of connective tissue cannot continue with just one functional copy of such FBN1 gene.

Buffering system of blood

When any acidic substance enters the bloodstream, the bicarbonate ions neutralize the hydronium ions forming carbonic acid and water.

The slope in the ice segment is steeper than in the water segment because more heat is required to raise the temperature of the ice.

Ice is heated by changing its phase from solid to liquid, or from ice to water. Melting is required to turn ice into water. Ice melts at 0 degrees Celsius. The temperature won't change until all the ice has melted. The temperature will begin to rise once all the ice has melted.

The transformation of water into gas comes next. Steam is produced when water boils. Water begins to vapourize at a temperature of 1000C. The temperature is unaffected by the phase change. Due to the strong intramolecular hydrogen bonds between water molecules, a large quantity of heat is needed. Before the water molecules can be transformed into vapors, the heat supplied is utilized to first break the hydrogen bonds between the water molecules. As a result, the ice segment's slope is steeper than the water segment's.

In the winter, the energy pyramid in a grassland community is thinner than in the summer. Thus,  the abiotic factor that determines the differences between the two pyramids is sunlight.

A grassland refers to an area that is mostly composed of grasses and shrubs. The grassland community depends heavily on the primary productivity from the green grasses. In turn the primary productivity of the grassland ecosystem depends on the energy from the sun.

When there is less sunlight, there would be less primary productivity and little energy is transported across the energy pyramid. The low primary productivity owes to a decreased amount of sunlight.

Hence, in the winter, the energy pyramid in a grassland community is thinner than it appears in summer when the sun is intense.

Keratinized stratified squamous epithelium differs from the function of nonkeratinized stratified squamous epithelium in that non-keratinized epithelium is permeable to water whereas cornified epithelium is impermeable to water. Moreover, the keratinized epithelium is an effective barrier, whereas the non-keratinized epithelium is a less effective barrier.

What is keratinized epithelium?

Keratinized epithelium is a stratified squamous epithelium found in the skin, the epidermis of the palms and soles, and masticatory mucosa. The keratinized epithelium forms an effective barrier. Its surface layer consists of dead cells. Keratin deposits on the surface. The cytoplasm of surface cells is replaced by keratin proteins. The keratinized epithelium is therefore dry and impermeable to water. It also provides better protection against scratches.

What is non-keratinized epithelium?

The non-cornified epithelium is a stratified squamous epithelium found in the lips, oral mucosa, alveolar mucosa, soft palate, the underside of the tongue, and the floor of the mouth. Unlike keratinized epithelium, the non-keratinized epithelium is moist and contains living cells in the superficial layer.

All are correct, the development of flower petals might cause increased attraction for pollinators, increased attraction for predators, and increased surface area for wind pollination.

Flowers' reproductive organs are encircled by petals, which are modified leaves. To draw pollinators, they are frequently brightly colored or shaped differently. The corolla is the collective name for a flower's petals. Functions of the petal include scent production and color changing which is used to attract pollinators and also attract predators.

Flowers also exhibit different types of pollination and wind pollination is one of it, for flowers that undergo wind pollination require little or no petal since the pollens are to be scattered by wind. The development of the flower's petal in terms of the size, scent, colour depends on what type of pollination, whether the flower attracts pollinators or/and predators.

The ID50 value is defined as the concentration of antiviral drug required to reduce the HSV-specific DNA by 50% compared with the untreated virus controls.

The median infective dose (ID50) of Cryptosporidium parvum and to describe the dose–response relationship including associated clinical illness in experimentally challenged dairy calves. Within the first 24 h of life, 27 test calves were experimentally challenged with C. parvum oocysts and 3 control calves were sham dosed. Test calves received 1 of 8 possible doses (25, 50, 100, 500, 1 × 103, 1 × 104, 1 × 105, and 1 × 106 oocysts).

The infective dosage, or ID50, is the average amount of organisms or virus particles expected to cause infection in 50% of healthy adult humans exposed by a specified pathway.

Here the virus with a much lower ID50 requires a lower viral load to infect a human compared to a bacteria with an ID50 of 100,000. Hence the virus has a higher infectivity then bacteria .

The ID50 value is defined as the concentration of antiviral drug required to reduce the HSV-specific DNA by 50% compared with the untreated virus controls. In the Clinical Virology Laboratory at Children's Hospital of Philadelphia, HSV isolates with in vitro ID50 values of ≥2 μg/ml for acyclovir and ≥100 μg/ml for foscarnet are considered resistant to these antiviral agents.

Explanation:

The NADH and FADH₂ are produced in the Krebs cycle are sent to the final step of cell respiration, electron transport chain. The Krebs cycle does not use oxygen because it runs on NADH and FADH₂.

Electron transport chain is a series of protein complexes and molecules which transfer electrons from one electron donor to the other electron acceptor via different redox reactions and couples this electron transfer reactions with the transfer of protons across the mitochondrial membrane. A series of proteins in the inner membrane of mitochondria are involved in the electron transport chain.

NADH and FADH₂ molecules are formed during the process of Glycolysis and Krebs Cycle which carry the electrons to the electron transport chain in the mitochondria. The electron transport chain runs on a proton gradient which ultimately leads to the production of ATP.

Membrane anchors are the hydrophobic groups that are covalently attached to proteins and tether them to the membrane.

Proteins are bound to membranes by different mechanisms. Some proteins are bound because the hydrophobic regions of the polypeptide chain cross the lipid bilayer several times, and therefore a substantial part of the protein is actually located within the hydrophobic interior of the bilayer (see membrane proteins).

Other proteins have a much weaker association with the membrane, using a relatively small membrane anchor for attachment. Depending on the particular protein, this membrane anchor can be a single hydrophobic segment spanning the membrane of the polypeptide, or a variety of different lipids covalently attached to specific sites in the polypeptide chain.

If the concentration of extracellular glucose is lower than the concentration already stored in the cells then the cell needs to undergo Active transport so as to take up the cell.

In the gut wall, active transport takes place. From a low concentration in the stomach to a higher concentration in the blood, sugar is moved with the aid of active transport. This makes it possible for the gut's glucose to be absorbed. The body uses this glucose for Respiration.

What is Active transport?

A type of cellular transport known as active transport involves the movement of materials (such as ions, glucose, and amino acids) across a biological membrane in the direction of an area where a lot of these materials are already present.

Because of this, active transport moves these molecules against their concentration gradient using chemical energy (such as ATP).

As a result, this activity calls for the use of energy as well as the support of membrane proteins such carrier proteins.
