Answer:
Most animals can easily digest this compound
Explanation:
Cellulose is a linear polymer of glucose comprising of beta 1,4-glycosidic linkage of glucose molecules; this is where it differs from starch. Cellulose is a polysaccharide made of glucose monomers just like starch. The enzymatic hydrolysis of cellulose is achieved by the enzyme cellulase.
Not all animals can digest cellulose. As a mater of fact, no vertebrate can digest cellulose directly. Many herbivorous animals possess symbiotic bacteria in their gastrointestinal tract which enables the digestion of cellulose. These bacteria possess the requisite enzymes for the digestion of cellulose.

Growth media are used to grow microorganisms in a lab setting. Some media are liquids; others are more solid or gel-like. A growth medium provides nutrients, including water, various salts, a source of carbon (like glucose), and a source of nitrogen and amino acids (like yeast extract) so microorganisms can grow and reproduce. Ingredients in a growth medium can be modified to grow unique types of microorganisms. For example; _____is a general-purpose, non-selective growth media, _____is a non selective, enriched growth medium with red blood cells that have been lysed by heat, Columbia Nalidixic Acid (CNA) and _____are selective agar for Gram positive organisms and ______agar is a selective agar for Gram negative organisms, Mannitol salt agar MSA is a commonly used selective and differential growth medium that encourages the growth of bacteria that ferments mannitol, and _____is an example of a liquid that supports growth of a variety of organisms.
Answer:
Growth media are used to grow microorganisms in a lab setting. Some media are liquids; others are more solid or gel-like. A growth medium provides nutrients, including water, various salts, a source of carbon (like glucose), and a source of nitrogen and amino acids (like yeast extract) so microorganisms can grow and reproduce. Ingredients in a growth medium can be modified to grow unique types of microorganisms. For example; Nutrient agar is a general-purpose, non-selective growth media, Chocolate agar is a non selective, enriched growth medium with red blood cells that have been lysed by heat, Columbia Nalidixic Acid (CNA) and Mannitol Salt agar are selective agar for Gram positive organisms and MacConkey agar is a selective agar for Gram negative organisms, Mannitol salt agar MSA is a commonly used selective and differential growth medium that encourages the growth of bacteria that ferments mannitol, Nutrient broth is an example of a liquid that supports growth of a variety of organisms.
Explanation:
Growth media are classified based on their composition as:
1. General Purpose Media: These type of media support the growth of non-fastidious organisms, that do not require special nutrients for growth, and they also serve as a base for certain modified media. An example is the nutrient agar
2. enriched media: these media, like the name implies, is one that has been modified by the addition of special growth factors and nutrients called enrichment. An example is chocolate agar where lysed blood is added to nutrient base agar, when the blood cells are lysed slowly at 80°C, nicotinamide adenine dinucleotide (factor V or NAD) and hemin (factor X), are released into the medium, and these support growth of certain fastidious organisms like Haemophilus influenza bacteria.
3. Selective media: These kinds of media contain substances that support the growth of certain organisms while in turn preventing the growth of others due to the presence of certain inhibitory factors. Examples are: Mannitol Salt Agar, which supports growth of Gram-positive organisms and MacConkey agar, which supports the growth of Gram-positive organisms
4. Non Selective media: These type of media have no biases against the growth of certain organisms, that is, they do not contain certain inhibitory factors that impede the growth of certain organisms.
5. Differential media: These media contain chromogenic agents that change colour and helps to differentiate one organism from the other, making for ease of identification especially for organisms with similar properties.
Finally, a broth is a growth medium that fo not contain agar, hence, it is liquid and not solid.

Ash trees are being removed when they show signs of the ash borer, a parasite that affects only ash trees and kills them off. What best explains why the ash trees are being cut down? The ash borer is a density-independent limiting factor, and humans need to clear cut to control tree density. The ash borer is a density-dependent limiting factor and will start to spread to nearby healthy trees. Ash trees are outcompeting other trees and are thus more affected by the ash borer. Changes in climate have decreased ash borer populations which indirectly increased the need for cutting down the trees.
Answer:
The ash borer is a density-dependent limiting factor and will start to spread to nearby healthy trees.
Explanation:
Ash borer is a parasite that affects ash trees it is highly destructive and invasive. It affects it Native host causing serious damages. Infected plant is cut down to avoid its spread to other healthy plant this is because ash bored when not control can destroy a whole population of ash trees in it Native environment within the space of 10 years. Its population dependent and would keep increasing in population and become more destructive. Thus, to avoid its spread infected trees are treated cut down and cut down.

Chloride ions, Cl-, follow actively transported Na+ ions from the nephrons into the blood. Would you not expect the Cl- concentration to decrease as fluids are extracted along the nephron?
Answer:
Bicarbonate ion, HCO3- (which has a similar charge to chloride ions) also follow sodium ions into the blood. Also, potassium ions, K+ are transported into the nephron so some chloride ions and bicarbonate ions remains in the nephron to balance the charge.
Explanation:
Sodium is the primary positively charged electrolyte in extracellular fluid. Most of the solute reabsorbed in the proximal tubule is in the form of sodium bicarbonate and sodium chloride. Water is also reabsorbed in order to balance osmotic pressure
When sodium ions are reabsorbed into the blood, few of the substances that are transported with Na+ on the membrane facing the lumen of the tubules include Cl- ions, Ca2+ ions, amino acids, and glucose. Sodium is actively exchanged for K+ using ATP on the basal membrane.
In the distal convoluted tubule, K+ and H+ ions are selectively secreted into the filtrate, while Na+, Cl-, and HCO3- ions are reabsorbed to maintain pH and electrolyte balance in the blood.
Some chloride ions remains in the nephron to balance the charge of the secreted K+ ions and also due to the bicarbonate ions that are removed.
The concentration of Chlorine decreases as fluids are extracted along the nephron because it is not soluble in water. With an increase in the fluid extraction along the nephron, there is the reabsorption of more water and since Chlorine cannot be diluted by water, its concentration decreases. With the more reabsorption of water and increase in its concentration as the fluid moves through the nephron, the relative concentration of chlorine reduces.
This gradient is mainly caused by NaCl and urea. NaCl is transported by the ascending limb of Henle's loop which is exchanged with the descending limb of the vasa recta.

what is the center of the DNA strand?
Answer:
It exhibits traits and metabolic instructions of the cell.
Explanation:
A DNA strand is a thin long molecule, with an average width of just around two nanometers. The remarkable thinness of the DNA strands allows them to be bundled very tightly fitted inside cells. Once DNA has been replicated adequately during the process of cell division, it is further wrapped together under a mechanism known as supercoiling. A non-condensed DNA is further condensed during supercoiling using a special protein known as a histone. A part of DNA packed around a large cluster of histones is called a nucleosome. Additional condensation leads to a chromosome or the most compact type of DNA that fits into the nucleus. It is also worth noting that this wrapping does not merely align DNA into a cell, but serves other objectives such as protecting DNA, thus ensuring metabolic instructions to the cell.

Explanation:
because conduction happens through solids and the others are obviously conventional current
The wax covering an iron rod melts when the rod is heated ( D ) is not a result of convection current
Convection is the transfer of heat energy from an area of higher concentration to an area of lower concentration and it occurs in fluids and gases. while conduction is the transfer of heat energy from one object to another through the direct contact of the objects and this occurs between solids.
The transfer of heat from the heated rod to the wax covering occurs because of the direct contact the wax has with the heated rod therefore it is conduction and not a convection current.
