Answer:
A) stripes of a skunk
Explanation:
The aposematic coloration is coloration that has been developed by the living organisms in order to warn the predators that they can be dangerous and harmful, thus to not attack them. Usually this type of coloration tends to stick out significantly when compared with the coloration of the other species that do not exhibit it, thus making it much more easy for the animal or plant to be recognized by the predators, which is benefiting both sides. The coloration of the skunk is a nice example of aposematic coloration. The skunk has black basis, but it has straight white stripes along its back. The two colors are contrasting, so it sticks out very easily. The predatory animals immediately notice it and just move along and do not bother the skunk because they are aware that it can pose a danger to them if they attack it.
Answer:
NAD is reduced
Explanation:
Glycolysis is the first step in the breakdown of glucose in order to generate energy for cellular metabolism. Glycolysis helps to convert glucose into pyruvate and hydrogen ion.
In redox reaction, oxidation is the removal of hydrogen and reduction is the addition of oxygen. In the process of glycolysis, the NAD is reduced to form NADH and H.
If NAD is not present, glycolysis will not be able to continue. During aerobic respiration, the NADH formed in glycolysis will be oxidized to reform NAD+ for use in glycolysis again.
Answer:
The correct answer is: B) codominance.
Explanation:
<u>Codominance is a type of inheritance pattern that describes the relationship of two variations of the same gene</u>: this means that in an individual, its two alleles manifest in the phenotype.
If a sunflower has both blue AND yellow speckles, it means that the two possible alleles are in a relationship, which makes these alleles CODOMINANT.
Answer:
d. the movement of myosin head while attached to actin myofilament
Explanation:
During muscle contraction, the calcium ions released from the sarcoplasmic reticulum in the sarcoplasm bind to troponin which in turn removes tropomyosin from the myosin-binding sites present on the actin. Hydrolysis of ATP at the myosin heads energize them. These myosin heads with stored energy bind to the myosin-binding sites on the actin filaments. In their bound conditions on the actin filaments, myosin heads are called cross bridges. Only one myosin head of a single myosin molecule forms cross-bridge at a time.
Answer:
Option B is correct.
Explanation:
Carbohydrate fermentation test; its main purpose is to know if a bacteria can ferment a specific carbohydrate or not. The test can be used for distinguishing bacterial species.
When fermentation of carbohydrate occurs, gaseous acids are produced. This production of the acid lower the pH of the medium undergoing the test, which can be detected by the color change of the pH indicator.
The Color changes only when sufficient amount of acid is produced. Phenol red can easily detect single acid production but METHYL RED NEED MORE ACID.
