Answer: Option C) Reduction is the gain of electrons.

Explanation:

Reduction is a process involving a gain of electron(s), while oxidation involves a loss of electron(s).

Thus, an oxidizing agent is a substance that accepts electron(s) and become reduced, while a reducing agent is a substance that donates electron(s) and so becomes oxidized.

Thus, reduction is the gain of electron(s)

kompoz [17]

Answer:

Explanation:

1. can generate energy – Both , In landfills methane gas is produced which is used to generate electricity, like wise heat energy produced in incinerator is also used for producing energy

2. emits toxins through combustion – Incinerators produce dioxins which is a dangerous chemical

3. drains liquids into the ground – Land fill, leachate is a common issue with all landfill site.  

4. releases greenhouse gases – Both, methane and other carbon gases are produced in both landfill and incinerators

5. requires a substantial amount of land – land fill site , needs a large land to dump the city waste

6. generate ash – Incenerator only

Cinnabar colored eyes (cn) and reduced bristles (rd) are autosomal recessive genes and lobe shaped eyes (L) is an autosomal domi
Morgarella [4.7K]

Answer:

The correct genotypic notation for a wild type with phenotypic characteristics: red eyes, long bristle and round eyes will be any of CNRDll, CnRdl, CnRDl or CNRdl if c, n, r and d are capable of independent assortment and CNRDl if they cannot.

Explanation:

The eye color and bristle size is coordinated by either recessive cn and dominant CN or Cn genes. The wild type in questions has red color eyes, which is a dominant trait coordinated by CN or Cn if c and n can undergo assortment independently or just CN if they cannot. The second characteristics of the wild type is long bristle. We were told that reduced bristle is coordinated by recessive rd Gene. Then the long bristle in our specimen wild type will have dominant genotypic notification of RD or Rd, depending if r and d can undergo assortment independently. The last trait is a round eyes, which is a recessive trait controlled by recessive allele l. Therefore, the combined characteristics of red eye color, long bristle and round eyes shape of the wild type will be CNRDl or any of CNRDll, CnRdl, CnRDl CNRdl depending on the segregation pattern of c, n, r and d.

Arlecino [84]
1) kinetic energy
2) water vapor
3) air
4) rain

The first one is a guess from my knowledge as a college bio student. I hope it’s what you’re looking for. Temperature is just the movement of molecules (hotter has more movement, colder has less)
