It plays an important role in digestion by ensuring that food goes down the esophagus (foodpipe) and not the trachia (windpipe)........
Answer: 1 Lysosomes and peroxisomes, Microtubules, Endoplasmic reticulum, Mitochondria
2 The role of the nucleus of a eukaryotic cell is to control the cell. Because it contains most of the cell's DNA, which is encoded with genetic instructions, the nucleus controls which proteins the cell makes.
3 The rough endoplasmic reticulum has ribosomes on its surface. This is what give the RER a "rough" appearance. The smooth endoplasmic reticulum (SER) does not contain ribosomes. The Smooth ER looks more like tubes. The SER helps in the storage of proteins and lipids.
4 Secretory vesicles contain materials that are to be excreted from the cell, such as wastes or hormones.
Transport vesicles move molecules within the cells.
Vacuoles are vesicles that contain mostly water.
hope this helps
Answer:
<u><em>These mutations form new alleles that increase genetic variation in a population. This variation may lead to new species which increases biodiversity.</em></u>
Explanation:
Mutations are randomly occurring modifications that exist within the genetic code, leading to replication errors in DNA. DNA molecules are long-chain, helical macromolecules that store genetic material. They consist of different monomer sequences called nucleotides. In a reading frame, which contains instructions for protein production, they shape base pairs and codon sequences.
Single nucleotide polymorphisms are normal, as silent mutations, which sometimes result in no changes in amino acids. Some mistakes add a random nucleotide (SNP) in point mutations resulting in new alleles.
Frameshift mutations occur from nucleotide insertions or deletions that are not divisible by 3. This results in the codon requiring more or fewer nucleotides which disrupt the reading frame, resulting in a separate protein translation.
Answer:
The answer is- A bundling relationship
Explanation:
Bundling is defined as when a company packages some of their products or services together as a single combined unit, often for a lower price than they would charge the customers if the items are sold independently or separately. This helps to facilitate the convenient sale of products or services from one company.
An example could be if Oral-B decides to sell both their toothpaste and toothbrush together as a single combined unit at a lower price than if selling the toothpaste or toothbrush separately.
BioMark Lifesystems' arrangement with the producer of syringes and test tubes to have diagnostic substances sold to laboratories in a package along with the syringes and tubes is called bundling relationship.
