Answer:
The correct answer is plants have two parts life cycle spending one part of their life in diploid phase and the other part in the haploid phase,human spending their lives in diploid phase and produces gamets that are haploid.
Explanation:
There are two stages in the life cycle of plant one is gametophyte stage which is haploid and the other is sporophyte stage that is diploid.
but in case of humans the overall life cycle proceed in diploid phase and produces gamets that are haploid.
In case of human male produces haploid gamet known as sperm and the female produces haploid gamet know as ovum. The sperm and ovum fuses to form diploid zygote,
Answer:
The reasons are explained below -
Explanation:
The large finches living on the Galapagos islands are different from the original source population from a nearby islands because of the following reasons -
- A natural selection favored only the large finches because they are more fit to the current environmental conditions.
- A genetic drift has been occurred in the two populations living on the nearby islands.
- Due to the separation of habitat on both the islands, the gene flow between the two islands is reduced.
All the above listed reasons are responsible for the difference in the finches found on the two islands.

Answer:
The correct option is option b that is<em> Homo erectus</em> is the common ancestor of<em> Homo neanderthalensis</em> and<em> Homo sapiens.</em>
Explanation:
<em>Homo erectus </em>appears about 2 mya, possibly during the Pleistocene epoch and are considered as direct ancestor of human.They are called as upright man as they use legs for walking without any support.They are thought to be capable of doing certain things like hunting, starting fire,art making, create speech etc.
<em>Homo neanderthal</em> was the most recent ancestor species of modern human as they appear about 40,000 years ago.
They became extinct as they did't fight against environmental hazards and the major cause of their extinction that scientists have claimed that they did't adapt the modern techniques that the modern human does.
