Which of the following are roles carbohydrates play in biological systems? Group of answer choices the basis of most of the organic matter on our planet (cellulose, chitin, etc.)

Here are the completed options

fuels

components of DNA and RNA

signalling

forming barriers between organelles

digesting enzymes

breaking up lipids for digestion

providing structure

The correct options are

most of the organic matter on our planet (cellulose, chitin, etc.)

Carbohydrates act as Body fuels

providing structure

Explanation:

Carbohydrates are biological molecules and are constituents of starches, sugars, glucose e.t.c and are made up of carbon, hydrogen and oxygen which are the major constituents elements of the most organic matter on the planet.

Carbohydrates is a body fuel that act as the major energy source in the body. It gives and provide energy in the body needed for biological activities.

In plants, carbohydrates make up part of the cellulose, giving plants strength and structure. carbohydrates is to form a structure called the glycocalyx.

the glands which are associated with each description is given below:

interphase

the period of cell growth when the cell synthesizes new molecules and organelles. the cell is not dividing and it constitutes the majority of the time spent in the cell cycle

prophase

changes occur in the nucleus and cytoplasm. the chromatin condenses to form structures (sister chromatids) visible with a light microscope and the mitotic spindle begins to form, but the nucleus is still in tact

prometaphase

the nuclear envelope fragments and the spindle microtubules attach to the kinetochores of the sister chromatids

metaphase

all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle

anaphase

begins when sister chromatids separate from each other and ending when a complete set of daughter chromosomes arrives at each of the two poles of the cell

telophase

the daughter nuclei form at the two poles of a cell

cytokinesis

the division of a cytoplasm to form two separate daughter cells. usually occurs during telophase during mitosis. this and mitosis make up to mitotic (m) phase of the cell cycle
