The hydrocarbons' surface.
Because the covalent link that exists between hydrocarbon surfaces is different from the surfaces to which the salamander can cling, the salamander has difficulties adhering to these surfaces.
The hydrogen bond is the bond that exists between hydrogen and a bigger molecule like nitrogen or oxygen, whereas a covalent bond includes sharing electrons.
<h3>What Are Hydrocarbons and What Do They Do?</h3>
Crude oil, natural gas, and coal are all examples of hydrocarbons, which are organic compounds made of hydrogen and carbon. The world's primary energy source and a highly flammable substance, hydrocarbons. Petrol, jet fuel, propane, kerosene, and diesel are only a few of its uses.

Those receptors are located in the head, where the eyes and ears are located.
Answer:
1. SnapDragon - incomplete dominance
2. Cows/chickens- multiple alleles
3. Blood type in humans - co-dominance
4. Skin and hair color - polygenic inheritance
Explanation:
1. Sometimes, the phenotypic expression of a recessive allele cannot be completely covered by that of the dominant allele. This is called incomplete dominance. Flowers of snapdragon and four'o clock plants are the example of such an event where the recessive allele for flower color, which is white is also expressed in heterozygous plants along with the dominant red color, producing pink flowers.
2. Multiple alleles determine the genetic traits of cows and chickens.
3. There are three alleles in humans that determine the blood type - dominant Ia and Ib for A and B type respectively, and recessive Io for O type. when in a heterozygous person, both dominant alleles are present, both are expressed phenotypically forming AB type blood. this is called Co-dominance.
4. Skin and hair color in humans is determined by multiple alleles present in different chromosomes. this is called polygenic inheritance.
Answer:
B
Explanation:
Chemical reactions occur when chemical bonds between atoms are formed or broken and the substances that go into a chemical reaction are called the reactants.
Answer:
Antiprotozoal drugs will be much cheaper to develop than antibacterial drugs as we have extensive knowledge of most of eukaryotic metabolic pathways. But some of their metabolic pathways are still unknown as they have multiple metabolic pathways.
Explanation:
- Antiprotozoal drugs are much cheaper than antibacterial drugs.
- But those drugs have some side effects. most of those drugs possesses side effects. Sometimes this could be fatal if they are not taken by the doctor's recommendation.
- Protozoans have multiple metabolism pathways, though most of them are known but there are still so many unknown facts to reveal.
