Prokaryotic cells lack

Correct Answer: Genes are located on DNA present in the chromosome Chromosomes are present in the nucleus of the cell

Correct Answer: 23

Explanation:

23 chromosomes are in a human gamete.

Human somatic cells have 46 chromosomes(23 pairs) but a gamete(germ cell) gets half the amount, i.e. 23 chromosomes, (one from each pair). There will be half the number of chromosomes an organism has in its somatic cells (all other body cells except gametes).

 

For example in humans, the somatic cells contain 46 chromosomes which are the diploid number (2n) and each sperm and egg has 23 chromosomes where one of them is the sex chromosome.

Correct Answer: DNA is called the blueprint of life because it contains the instructions needed for an organism to grow, develop, survive and reproduce DNA does this by controlling protein synthesis Proteins do most of the work in cells, and are the basic unit of structure and function in the cells of organisms

Correct Answer: Yes

Explanation:

While plant cells have chloroplasts to photosynthesize, they also require ATP for cellular functions, and do use oxygen to break down some of the sugar they produce in order to generate that ATP. Cellular respiration takes place in the mitochondria. They need mitochondria for this reason.
Hence with this logic, we can say that Plants cells have mitochondria.

Correct Answer: The cell grows

Explanation:

The cell carries out the metabolic processes and it grows during interphase.

The cell cycle has three phases that must occur before mitosis, or cell division happens. These three phases are collectively known as interphase. They are G1, S, and G2.

Correct Answer: All the carbon atoms in glucose ultimately incorporated during cellular respiration into carbon dioxide molecule

Explanation:

All the carbon atoms in glucose ultimately incorporated during cellular respiration into carbon dioxide molecules.

Correct Answer: Chloroplast

Explanation:

The endomembrane system is composed of the different membranes that are suspended in the cytoplasm within a eukaryotic cell. These membranes divide the cell into functional and structural compartments or organelles. In eukaryotes, the organelles of the endomembrane system include the nuclear membrane, the endoplasmic reticulum, the Golgi apparatus, lysosomes, vesicles, endosomes and the cell membrane, among others.

Correct Answer: are nutrient-poor environments

Correct Answer: only during cell division

Explanation:

During most of the cell cycle, interphase, the chromosomes are somewhat less condensed and are not visible as individual objects under the light microscope. However during cell division, mitosis, the chromosomes become highly condensed and are then visible as dark distinct bodies within the nuclei of cells. The chromosomes are most easily seen and identified at the metaphase stage of cell division and most of the chromosome images in this gallery are pictures of metaphase chromomosomes.

The cell division takes place in mitosis stage.

Correct Answer: Bile contains bile acids, which are critical for digestion and absorption of fats in the small intestine Since bile increases the absorption of fats, it is an important part of the absorption of the fat-soluble substances, such as the vitamins A, D, E, and K Besides its digestive function, many waste products, including bilirubin, a byproduct of red blood cells recycled by the liver are eliminated from the body by secretion into bile and elimination in feces
