A population of white, grey, and black lizards lives on a volcanic island, and each phenotypic color has an equal chance of surv

ival. However, after the latest
volcanic eruption, 75 percent of the island was covered with volcanic ash and hardened lava flows. This event caused the black lizards to be naturally selected
over the white and grey lizards. This change is an example of what type of microevolution?
A) stabilizing selection
B) normal distribution
C) directional selection
D) disruptive selection

I would say disruptive selection, because the sudden eruption of the volcano disrupted the circumstances of the lizards, allowing the black ones to survive better because of camouflage against the black rock.

Hope this helps!

Sauron [17]

Nucleic acids, proteins, carbohydrates, and lipids are the four major types of biomolecules that form all living things. These biomolecules consists of monomers linked together by covalent bonds to form polymers.

  • Nucleic acids, proteins, carbohydrates and lipids can be classified according to their basic elements, monomer constituents, and functions.

Basic elements:

  1. Nucleic acids: Hydrogen (H); Carbon (C); Oxygen (O); Nitrogen (N); Phosphorous (P)
  2. Proteins: Hydrogen (H); Carbon (C); Oxygen (O); Nitrogen (N); Sulfur (Z)
  3. Carbohydrates: Hydrogen (H); Carbon (C); Oxygen (O)
  4. Lipids: Hydrogen (H); Carbon (C); Oxygen (O); Phosphorous (P)

Monomer constituents:

  1. Nucleic acids: nucleotides
  2. Proteins: amino acids
  3. Carbohydrates: monosaccharides
  4. Lipids: fatty acids and glycerol

Functions:

  1. Nucleic acids: contains the hereditary information to synthesize proteins
  2. Proteins: regulate metabolic processes (enzymes), the main biomolecule of cellular structures
  3. Carbohydrates: store energy (short term); form cellular structures
  4. Lipids: store energy (long term); the main component of biological membranes

Examples:

  1. Nucleic acids: DNA and RNA
  2. Proteins: lactase; collagen
  3. Carbohydrates: starch (polysaccharide); glucose (monosacharide)
  4. Lipids: phospholipids; cholesterol

What type of stimulus is required for an action potential to be generated? What type of stimulus is required for an action poten
Ivahew [28]

Answer:

A threshold level depolarization.

Explanation:

In a neuron, the action potential threshold is known as the point of depolarization where the neuron fires, when the neuron reaches a point, it will fire and if it does not reach the point of depolarization, it will not fire and it helps to transmit the information to another neuron.

A neuron transmits the information with the help of electric impulses which are sent through its axon. When a neuron in an inactive phase, more +ve charged ions recline outside the axon membrane. In the process of stimulation, the axon membrane admits more Na+ ions and providing the neuron more +ve charge.
