A class of lipids derived from cholesterol are called steroids.
Steroids are important large class of biological molecules which are significant components of cell membrane and signaling molecules.
Answer:
A. By releasing toxins that poison your cells
B. By using your cells to make copies of themselves
Explanation:
Within the body, bacteria can divide (multiply) and kill host cells by disrupting their normal functioning. Moreover, bacteria secrete toxins that are able to destroy host cells' metabolic machinery. For instance, many bacteria synthesize exoenzymes and interferons that disrupt and destroy host cells. Bacterial toxins can be synthesized internally in order to develop sensitivity through antigenic properties.
<span>Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes. Both also contain similar membranes, cytosol, and cytoskeletal elements.</span>
Answer:
To cross petunia plants/lines with pink flowers (F1) which were obtained by crossing plants with red and white flowers (parental generation). The presence of petunia plants with red or white flowers in F2 would evidence that this trait is under incomplete dominance.
Explanation:
Incomplete dominance is a type of relationship in which both alleles are expressed in heterozygous individuals, thereby resulting in a new phenotype. This type of allelic interaction is commonly referred to as 'the dilution of the dominant allele' in heterozygous individuals. Moreover, codominance refers to a type of allele relationship in which both alleles are expressed to an equal degree in heterozygous individuals.
Answer:
animals
Explanation:
Animals are technically not made from nature, while all the others are made from natural resources.
Hope this helps! have a good day :)
