Explanation

The outer part of the DNA helix is made up of sugar (deoxyribose) and phosphate molecules, which form the backbone of the DNA double helix.

This sugar-phosphate backbone is referred to as the "upright" or "backbone" of DNA.

Explanation

Chromatin is the chemical material that makes up chromosomes, consisting of DNA, histone proteins, and other non-histone proteins.

It's the complex of DNA and proteins that form the chromosome.

Explanation

Homologous chromosomes are pairs of chromosomes that are similar in shape, size, and genetic content, and have the same position of the centromere.

They contain the same genes in the same order, but may have different variations of those genes (alleles).

Explanation

Inheritance refers to the transmission of traits or characteristics from parents to offspring through the passing down of genetic information.

It's the process by which genetic traits are inherited.

Explanation

The female gametes (eggs) are fertilized in the fallopian tube, which is also known as the oviduct.

The fallopian tube is the narrow tube that connects the ovary to the uterus, and it's where the sperm fertilizes the egg.

Explanation

The male gonads in rabbits, as in all mammals, are the testes (singular: testis).

The testes are responsible for producing sperm and testosterone.

Explanation

In angiosperms, the 3N (triploid) zygote develops into the endosperm, a nutrient-rich tissue that surrounds and nourishes the embryo in the seed.

The endosperm is formed when the fertilized central cell of the embryo sac (3N) divides and grows.

Explanation

The female gametophyte of angiospermic plants is the embryo sac.

It ilso known as the megagametophyte.

It is the haploid (containing one set of chromosomes) structure within the ovule that contains the egg cell and is responsible for fertilization.

Explanation

Apomixis is a type of seed production that occurs without the fusion of male and female gametes (fertilization).

Instead, an egg cell develops into a seed without being fertilized, resulting in offspring that are genetically identical to the parent plant.

Explanation

Suckers are shoots that arise from buds on the base of a parent plant, often at the soil line or just below.

They are a type of vegetative propagation, allowing the plant to produce new stems and roots.

Suckers can grow into new individuals, eventually forming a clump or colony.
