Varieties of plants in which self-fertilization produces offspring that are identical to the parents are referred to as true-breeding. In this process the parents will pass down specific phenotypic trait of their offspring. True bred organisms will have pure genotype (genetic make up of an organism) and will therefore produce certain phenotype.
Answer:
D. Water is the most abundant atom in Earth’s atmosphere.
Explanation:
An atom can be defined as the smallest particle of an element (e.g., oxygen, hydrogen, etc). Water is a molecule (H2O) because its atoms are connected by molecular bonds (i.e., water is not an atom). Water is the most abundant molecule on the Earth's surface which covers more than 70 percent of the world's surface. A water molecule contains one oxygen (O) and two hydrogen (H2) atoms which are connected by covalent bonds. Water is also a compound known as a diatomic molecule, i.e., a molecule composed of two atoms of the same type.
Answer:
trend toward a sporophyte-dominated life cycle
the trend toward larger gametophytes
Explanation:
<em>The major trend in the evolution of land plants is the domination of the sporophytic phase in the life cycle and alternation of generation. It also moves towards a larger gametophytes</em>
In lower plants, the gameophyte phase was dominant in the life cycle while in bryophyte, both gametophyte and sporophyte phase are co-dependent.
The sporophyte phase is the diploid phase while the gametophyte phase is the haploid phase.
Also, the gameotyptic stages are quite microscopic (usually in the form of spores) in lower plants while they become bigger in land plants (in the form of ovary and pollen) although with fewer cells.
