Answer:
the movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy.
Explanation:
Answer:
Vascular have a system that is intricate and the plant can move water to distribute it to the whole plant. Vascular plants are able to grow bigger due to this ability. Example of this would be a tree or a flower Non vascular plants are usually small plants that are close to the ground.
Explanation:
Bryophytes, which evolutionarily precede tracheophytes, are plants that lack true vascular tissues by which to circulate liquids. These plants include mosses, hornworts and liverworts. Tracheophytes, which comprise about 93 percent of all land plants, all possess vascular systems that permit the internal circulation of liquids and nutrients.

each tropic level gets only 10% of the energy from the thing it eats because that organism uses loses energy when it moves or by heat.
Answer:
C, B, A, D
Explanation:
The images in this question is portraying the stages involved in MITOSIS, which is a kind of cell division that forms two genetically identical daughter cells. The four stages of mitosis represented in the image are as follows: interphase, prophase, metaphase, and anaphase
- INTERPHASE: This stage is regarded as the resting stage of the cell. The chromosomes are found to be supercooled together as chromatins as seen in image C.
- PROPHASE: In the prophase stage, the chromosomes become condensed and more visible as seen in image B.
- METAPHASE: In the metaphase stage, the chromosomes align at the equator of the cell in order to be pulled apart by microtubules as seen in image A.
- ANAPHASE: In the Anaphase stage, the chromosomes are pulled apart into opposite poles of the cell as depicted in image D.
Answer:
Dominant traits are always expressed when the connected allele is dominant, even if only one copy of the dominant trait exists. Recessive traits are expressed only if both the connected alleles are recessive.
