Answer:
microtubules more chromosome motor protein required energy in the form of ATP ATP hydrolysis result in a conformational change that allows the protein to mobile of microtubule actor
Answer:
B. No
Explanation:
First, let's watch what it looks like when a population is not evolving. If a population is in a state called Hardy-Weinberg equilibrium, the frequencies of alleles, or gene versions, and genotypes, or sets of alleles, in that population will stay the same over generations (and will also satisfy the Hardy-Weinberg equation). Formally, evolution is a change in allele frequencies in a population over a very long period of time, so a population in Hardy-Weinberg equilibrium is not evolving.
Answer:
Diffusion : Is the movement of molecules / ions from a region of higher to lower concentration. It may or may not occur across a semi permeable membrane.
In diffusion there is no challenge involved as it is along the concentration gradient, but in active transport movement of molecules occur against concentration gradient ie; from lower to higher concentration.
2) For active transport, energy is vital for movement, in this case protein molecules function as molecular pumps to enable the cell accumulate glucose/ions, against concentration gradient. Here metabolic energy ATP is required.
3)Facilitated diffusion is a type of passive transport in which ions/molecules cross the semi permeable membrane because permeases present in the membrane facilitate the transport.
Like simple diffusion facilitated diffusion doesn't require metabolic energy and simply occurs across the concentration gradient.
4) Osmosis : is movement of water from hypotonic solution (lower concentration) to hypertonic solution (higher concentration) through a semi permeable membrane.
The cell membrane being permeable to water allows to and fro movement of water molecules along the concentration gradient.
Carolus Linnaeus is considered to be the founder of the binomial classification system, and he <span>thought that resemblances among different species reflected the pattern of their creation.
Linnaeus studied the morphological and physiological similarities of organisms as well as tracing back their common ancestors. From these similarities, he named the organisms based using their genus and species name giving rise to the binomial nomenclature.
