Answer:
A. They have different genetic sequences but are found in the same location on a chromosome.
Explanation:
In genetics, alleles are the variant form of a gene. According to Mendel, there are usually two alleles for most genes except for few cases where there are multiple alleles. Each allele of a pair is contributed by each parent during sexual reproduction. For example, in a gene Tt, the alleles are T for tallness and t for shortness.
Alleles of the same gene are related in such a way that they have different genetic sequences but are found in the same location on a chromosome. The different genetic sequences makes them alternative form of each other.
Answer:
Summary Sugar Transport. Sugars, which are formed by the plant during photosynthesis, are an essential component of plant nutrition. Like water, sugar (usually in the form of sucrose, though glucose is the original photosynthetic product) is carried throughout the parts of the plant by the vascular system.
Explanation:
The correct answer is C, i.e., Passeur domesticus. According to binomial nomenclature, the name of the genus is started with a capital alphabet and name of the species is started with the lower alphabet. Further, it should also be in italics or alternatively may be underlined
I believe the biggest space mission of the twenty-first century will be a manned mission to Mars, and the colonization that follows. This is the stated goal of several nations, companies, and individuals, all with considerably deep pockets. This mission will not only be a huge leap forward in space exploration, it will usher in a new era in human history in which the human race is an interplanetary civilization, a natural milestone as humanity continues to progress and advance.
Significant challenges are many and overwhelming. In terms of getting to mars, we need efficient, powerful propulsion systems and a spaceship that can not only accommodate a full crew for a mission that would likely last years, but withstand the various hazards that a long trip through space and entrance into the Martian atmosphere will entail. In terms of colonization, significant challenges will include establishing efficient and frequent travel/transport between the planets, and in the longer term, the necessity to terraform the planet (make it more like Earth) so that humans can more easily live there.
The stage is the last stage of speciation The populations become adapted to different environments and eventually become so different that they cannot interbreed to produce fertile offspring.
Speciation is split into 3 stages:
a) Separation.
b) Adaptation.
c) Reproductive Isolation.
Stage 1 Separation
- A part of the populace separates and adapts to a brand new environment. Natural occasions along with tsunamis, tidal waves can reason organisms to split from their preliminary habitat to a brand new environment.
Stage 2: Adaptation.
- At this stage, the organisms evolve new trends that permit them to a brand new environment. They own sure traits that permit them to match into the brand new environment. Example The notable white skin's color makes it tough for it to be visible withinside the dark.
Stage 3: Reproductive Isolation.
- At this stage, organisms of the equal species reunite and do now no longer interbreed. e, species are remoted into new ones in order that they have the great diversifications for or her new habitat.
<h3>What is speciation?</h3>
Speciation is an evolutionary method where the new species arises from previous ones.
Hence concluded that speciation involves the stage where the populations become adapted to different environments and eventually become so different that they cannot interbreed to produce fertile offspring.
