You can rub a permanent magnet against something else that can be magnetized, like a paper clip.
Answer:
Functions of epithelial cells include secretion, selective absorption, protection, transcellular transport, and sensing. Epithelial layers contain no blood vessels, so they must receive nourishment via diffusion of substances from the underlying connective tissue, through the basement membrane
Answer:
Consumers use chemical energy from the chemical bonds within organic molecules such as carbohydrates, lipids, and amino acids.
Explanation:
<u>Heterotrophs are consumers</u>; they ingest or absorb organic matter (lipids, carbohydrates, proteins, etc.) made by autotrophs or producers for their energy consumption. Autotrophs include plants, bacteria, and other photosynthesizing organisms, while heterotrophs include animals, fungi, protists, and bacteria.
Heterotrophs obtain energy from food through the process of cellular respiration. For instance, during aerobic respiration in mitochondria, they break down sugars in the form of glucose into carbon dioxide and water to obtain energy in the form of ATP or adenosine triphosphate.
aerobic respiration: C6H12O6+ 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP
glucose+ oxygen → carbon dioxide+ water+ energy
Answer:
The red kernels are the dominant trait and will be more numerous on the ear of corn than the yellow. This happens because its dominance mearns that if it is a combination of either RR or Rr, it will still take over the r trait. The only time the yellow can be expressed entirely Is when the combination is rr.
Answer: 2 alleles
The number of the allele that a gene contains could be various. The allele will determine the phenotype of the organism, so more allele means more possible combination. There is only 1 gene that control the corn height and that gene only has two alleles. So, the total allele that controls the corn height should be: 1 gene * 2 alleles/gene= 2 alleles
