Plant cells have features that animal cells do not have - a cell wall, also they have a large central vacuole, and plastids such as chloroplasts.
hope it helps -Noelle
Answer:
they are of the same genus but not of the same species and therefore they cannot mate to give rise to fertile off springs only organisms from the same species are able to give rise to fertile offsprings
Answer:
Facilitated diffusion
Explanation:
Facilitated diffusion is the transport of hydrophilic molecules that can not freely cross the membrane. Channel protein and many carrier proteins are in charge of this transport. When uncharged molecules cross the membrane, they do it according to their concentration gradients, going from the more concentrated side to the lower concentrated one. When ions need to cross the membrane, the process depends on an electrochemical gradient.
Facilitated diffusion is a passive transport process because they only depend on electrochemical gradients, so they do not need any energy to occur.
Answer:
The correct answer is <em>B. False</em>
Explanation:
<em>The genotype of an organism determines its phenotype</em>. Phenotype is constituted by observable characteristics of an organism. These characteristics are codified by genes, and the combination of the differents variants of a gene which codify a phenotipic characteristic constitutes the genotype. For example: eyes color is a characteristic. Its is codified by variants of a gene. The combination of two variants of a gene gives a genotype, which codifies for the phenotype 'blue eyes'.
Answer:
The ecological footprint may be defined as the dependency of humans on nature. The ecological footprint support the economy or people of the country.
The main consequences that are related to the ecological footprints are the depletion and decrease of the natural resource. This might also cause the habitat loss of other species and the habitat fragmentation as well. The consequences also includes the increase in the pollution and natural calamities in an area.
