<span>The process must occur before the gametophyte generation is Sporophyte. A sporophyte is the diploid generation of a plant or alga that has a double set of chromosomes. [ All land plants, and some algae, have life cycles in which a multicellular haploid gametophyte generation alternates with a multicellular diploid generation. In the Gymnosperms and flowering plants (Angiosperms), the sporophyte generation is the most prominent phase, comprising the familiar green plant with its roots, stem, leaves and cones or flowers. In the flowering plants, the gametophytes are very reduced in size, and are represented by the pollen and the embryo sac.</span>
Answer:
The purpose of the outer covering of the bird helps keep it warm and to help it fly, whilst the outer cover of the tree is to protect it from bugs.
Explanation:
The second law of thermodynamics says that the transfer of energy is imperfect. For example on Newton’s cradle, as GPE is transferee to kinetic energy and back, energy is lost due to gravity forcing the balls down and eventually the motion stops
A abiotic factor because it is a nonliving thing in our ecosystem.
<u>Mutations</u> would cause a change in the phenotype of the offspring that was NOT present in the parents.
Explanation:
A mutation causes a change in the initial DNA sequence. Mutation can be deletions, insertion, inversion, substitutions. Mutations can change the phenotype of an organism because they interfere with codons that code for amino acids. Some mutations are lethal, other advantageous while others are silent. These mutations can also be passed down to offspring but only if they can be borne in gametes.
