Answer:
Euglena is a protist and it moves with the aid of structures called flagella
Explanation:
Flagella are known as locomotive cells which propels from the body parts of organisms . They are made of protein structures and formed in a helical manner.
They are whip like structures and usually helps in the movement of the protists through liquid surfaces through the whip like movement of the flagella.
Answer:
be part of the cell signaling process
Explanation:
Glycoproteins and glycolipids are proteins and lipids with carbohydrate chain attached to it. They are an important component of the cell membrane with many roles:
- stabilizing membrane structure-because of their ability to bind water molecules via hydrogen bonds
- cell signaling-they are often membrane receptors for the hormones and neurotrasmitters
- cell attachment (adhesion)-for the connection between cells
- cell recognition-they can act as antigens on the cell surface (immune role)
Answer:
The given blank can be filled with a venule.
Explanation:
A small blood vessel in the microcirculation, which connects the capillary beds to the veins is known as the venules. Various venules combine to form a vein. The walls of a venule are formed of three layers, that is, the inner endothelium formed of squamous endothelial cells, a middle layer of elastic and muscle tissue, and an external layer formed of fibrous connective tissue.
The size of a venule ranges from 8 to 100 micrometers in diameter and are produced when capillaries come in close association. A venule refers to a small blood vessel that permits the deoxygenated blood high in carbon dioxide and waste products to return from capillary beds to the bigger blood vessels known as veins.
Answer:
Change in the structure of chromosome.
Explanation:
Chromosome structure mutations are the changes that occur in the structure of chromosomes rather than just individual nucleotides. These mutations occurs due to the errors that happens in cell division that leads to the breaking in section of a chromosome, which can be duplicated or move onto another chromosome. Chromosome mutation is the process of change in the chromosomes that occurs due to the rearranged chromosome parts and abnormal numbers of individual chromosomes.
A hypothesis is a testable possible explanation, while a theory is an explanation that has been tested extensively.
