Nucleus - Stores the DNA and coordinates the cell's activities

Mitochondria - Make energy out of food

Vacuole - Storage for food and water

Lysosome - Contains digestive enzymes that help break down food


Plant cells (only) -

Cell wall - Protection and support

Chloroplast - Uses sunlight to create food using photosynthesis


I hope this helps :)

When is the kinetic energy of a pendulum the least?
Gwar [14]

▪▪▪▪▪▪▪▪▪▪▪▪▪  {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪

The Correct choice is ~

" At the top of the swing where it briefly stops before changing direction "

before changing the direction, it stops for a while therefore the kinetics energy is almost zero at that particular moment ~

During meiosis homologous chromosomes often twist around each other break exchange segments and rejoin this process usually cont
Annette [7]

Explanation:

Crossing over, or genetic recombination contributes to genetic variation and diversity.

In early Prophase I of meiosis, crossing over occurs. This is the exchange of segments of chromosome, between non-sister homologous or similar chromatids crossing over happens at chiasmata, the point where non-sister chromosomes are joined. The chromosome pairs form tetrads held together at chiasmata.

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. To produce daughter cells, the chromosomes (total number of chromosomes (2n)) are copied before the cell splits into two daughter cells. This process is known as mitosis, and occurs in cell division and growth processes. Two new nuclei are formed, along with identical cells. These are the same as the parent cell and the chromosome number (2n) is maintained. Conversely in meiosis, the number of chromosomes (2n) is halved through meiotic divisions, producing 4 (n) germ cells (sperm or eggs), each containing half the number of chromosomes as its parent cell.

During the process of prophase I one the nuclear envelope containing chromosomes has only partly broken down homologous chromosomes are joined together by proteins and a complex or pairing call synapsis- corresponding genes on chromatids are aligned precisely. The syanpsis allows for crossing over which is the exchange of segments of chromosome, between non-sister homologous or similar chromatids crossing over happens at chiasmata, the point where non-sister chromosomes are joined.

Crossing over contributes to genetic variation and diversity; novel gene combinations in gametes are formed, which are not present in parent chromosomes. Genetic diversity describes all the genetic characteristics or traits within a species.
