Evolution acts upon the population of organisms and not on each individual organism

Biology

Evolution can be defined as the process of changes in the genetic pool of a population over time. The process of natural selection operates the evolution of any population. Evolution acts upon a whole population instead upon on single individual. A single individual doesn't evolve, instead ratios of the genetic types within a population changes when it is evolving, and eventually, complete evolution occurs.

Hence, the given answer is 'true'.

The complement pathway is a critical mechanism for eliminating microbes, and is comprised of more than 30 proteins that are cons
BaLLatris [955]

Answer:

3. Antibody-independent pathways of complement activation rely on complement components that directly bind to microbial surfaces.

Explanation:

There are three pathways of complement activation:

  • The classical pathway.
  • The alternative pathway.
  • The lectin pathway.

The classical pathway is triggered by binding of C1 either to the pathogen surface or to antibody bound to the pathogen.

The alternative pathway is triggered by the spontaneous hydrolysis of soluble C3 to C3(H₂O) and initiates eventual deposition of C3 convertase on microbial surfaces.

The lectin pathway is triggered by the binding of mannose-binding lectin or ficolins to carbohydrate residues in microbial cell walls and capsules.

How can a black hole tunnel to another universe
irga5000 [103]

Answer:

According to a mind-bending new theory, a black hole is actually a tunnel between universes—a type of wormhole. The matter the black hole attracts doesn't collapse into a single point, as has been predicted, but rather gushes out a "white hole" at the other end of the black one, the theory goes.

PLEASE HELP!!!!!!!
lys-0071 [83]

Answer:

When the required direction of transport is opposed to concentration levels, a cell <u>will </u> expend energy to force<u> ions</u> across its membrane.

Explanation:

If the concentration gradient is opposite to the direction of transport of minerals, then the cell will use energy to transport mineral ions from a lower concentration to a higher concentration. The most common process through which this happens is termed as the active transport.

The process of active transport is opposite to passive transport. In passive transport, molecules move from a higher concentration to a lower concentration.
