A.) sexual phenotypic traits

Answer:

b) extreme

Explanation:

Disruptive Selection:

  • Disruptive or diversifying selection is a form of natural selection that favors phenotypes on the extreme ends of the trait/characteristic spectrum over intermediate phenotypes.
  • This occurs in environments where two extreme traits are the fittest to survive and successfully produce offspring.
  • London's peppered moths are one of the most prominent examples of disruptive selection. The rural environment favored moths with lighter colour but the darker coloured moths were easily spotted by predators.
  • On the other hand, industrial areas favored darker coloured moths as they could easily camouflage in the polluted surroundings. Here, the lighter moths were the ones to be easily spotted by predators.
  • However, moths of intermediate shades were easily spotted in both environments as they couldn't camouflage easily.

Every cell must remove its wastes. This function is performed by _____.
solniwko [45]

The correct answer is: B. the lysosomes.

Lysosomes are single-membrane organelles found in eukaryotic cells. Lysosomes are specialized vesicles created in the rough endoplasmic reticulum (rER) with a variety of enzymes inside it. Their function is digestion: of the food or of the cell when it dies and that function is performed via enzymes.

Toward an Artificial Cell Scientists have recently constructed an artificial ribosome in vitro from purified ribosomal proteins
dalvyx [7]

Answer:

RNAs and proteins can bind via electrostatic interactions, hydrophobic interactions, Hydrogen bonding interactions and base stacking interactions

Explanation:

Proteins bind to nucleic acids (i.e., both DNA and RNA) through different types of interactions:

- electrostatic interactions, also known as van der Waals interactions, refer to attractive/repulsive interactions between molecules depending on their electric charges.

- hydrophobic interactions, i.e., interactions between nonpolar molecules and water molecules

- Hydrogen bonding interactions resulting from the interaction between a hydrogen (H) atom that bind to an electronegative atom (e.g., N, O, F, etc), and another electronegative atom.

- base stacking interactions that result from the arrangement of RNA nucleotides

In this case, it is also important to highlight that the interaction will depend on the specific tertiary structure of ribosomal proteins and ribosomal RNAs (rRNAs).

There are three ways that natural selection can chnage a population. list all three of them AND then describe atleast 2 of them.
Gre4nikov [31]

Answer:

Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results.

Explanation:

Evolution, in genetic terms, involves a change in the frequency of alleles in a population over time. What are the sources of genetic variation? Three sources of genetic variation are mutation, genetic recombination during sexual reproduction and lateral gene transfer.
