bagirrra123 [75]
Yes. The gradient determines the direction of movement for particles. Diffusion and osmosis are both examples of passive transport Osmosis is the diffusion of water through semipermeable membranes like the cell membrane

The particles will move from an area of high concentration to an area of low concentration. This direction of movement is described as movement *with* the concentration gradient.

An experiment was conducted to determine whether a deficiency of carbon dioxide in the soil affects the phenotype of peas. Liste
SSSSS [86.1K]

Answer:

No

Explanation:

The results of the phenotype do not make any sense in relation to the main aim of the experiment.

Smooth, wrinkled, yellow, green describe attributes relating to seed texture and flower colours in a result that simulates that of a plant breeding experiment, rather than a plant physiology experiment.

The determination of the effects of carbon dioxide deficiency in the soil on the phenotypes of peas is a physiological experiment. Hence, a result in the form of a plant breeding experiment would make not be relevant.

A frameshift mutation is a dangerous mutation because it
miv72 [106K]

Answer:

"A frameshift mutation is a type of mutation involving the insertion or deletion of a nucleotide in which the number of deleted base pairs is not divisible by three. "Divisible by three" is important because the cell reads a gene in groups of three bases. Each group of three bases corresponds to one of 20 different amino acids used to build a protein. If a mutation disrupts this reading frame, then the entire DNA sequence following the mutation will be read incorrectly."
