Front

What is the centromere?

Back

The centromere is the region of a chromosome where the two sister chromatids are joined together. It plays a crucial role during cell division, ensuring proper segregation of chromosomes.

Front

What type of transport is facilitated diffusion?

Back

Facilitated diffusion is a type of passive transport that allows substances to cross membranes with the assistance of special proteins, without the use of energy.

Front

What is the haploid number of chromosomes in a goat with 60 chromosomes in its body cells?

Back

The haploid number is 30, which is half the total number of chromosomes in diploid cells.

Front

What are lipids?

Back

Lipids are a group of organic molecules that are insoluble in water, including fats, oils, and waxes. They are important for energy storage, insulation, and making up cell membranes.

Front

What makes up the sides of a DNA ladder?

Back

The sides of a DNA ladder are made up of sugars and phosphates, which form the backbone of the DNA structure.

Front

Define chromosomes.

Back

Chromosomes are long, thread-like structures made of DNA and proteins that contain genetic information. They are found in the nucleus of eukaryotic cells.

Front

What is active transport?

Back

Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, using energy in the form of ATP.

Front

What are proteins?

Back

Proteins are large, complex molecules made up of amino acids. They play many critical roles in the body, including building tissues, acting as enzymes, and supporting immune function.

Front

What are nucleic acids?

Back

Nucleic acids, such as DNA and RNA, are biomolecules that store and transmit genetic information. They are composed of nucleotide monomers.

Front

What is osmosis?

Back

Osmosis is the diffusion of water molecules through a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.
