Four groups of organic compounds found in living things are lipids, carbohydrates, proteins, and nucleic acids.
Answer:
Yes it is (we already have one)
An international orbiting space station would be a great idea! We could use the space station as a refueling point for passing spaceships. This could helps us achieve things such as space exploration, mars/moon colony, or even contact with other unearthly organisms. This could also allow us to conduct space research.
No it isn't
An international orbiting space station is a horrible idea! The first thing to think about is the money. This would put the entire area in stasis as we try to raise money for the space station. We also need contact with the humans/robots in space! Building a space station would confuse other nations as to what we plan to do with said space station. This could cause a war of some sort.
Answer/Explanation:
Types of reproductive isolation include: temporal, ecological, mechanical, and behavioural.
A snail with a flat disc-like shell will not be able to mate with a snail having a conical shell - this is an example of mechanical isolation, where the animals are physically unable to mate due to incompatible body shapes and sizes.
The reproductive organs of male bush babies do not match with the reproductive organs of females of other bush baby species. - this is another example of mechanical isolation, as the sexual organs will physically not allow reproduction between these species
The mating call of a cricket is not recognized by a cricket of other species - this is an example of behavioural isolation, which results from incompatible mating rituals. I.e. the animals do not respond to each others mating behaviours
The signals sent by a male firefly are not recognized by the female firefly of other species. - this is also an example of behavioural isolation.
Temporal isolation is where species cannot interact because they do not have the same mating seasons or are not active at the same type of day. ?Ecological isolation occurs when two species do not come into physical contact to one another because they access different areas of the habitat. E.g. mating zones, food sources or nesting sites.
Im not sure cuz why theres O in there? I thought there’s only 4 bases Adenine Thymine Guanine Cytosine and in RNA there’s Uracil instead of Thymine. Sorry
this statement is False. prenatal development stages in order go from the germinal stage, embryonic stage, and the fetal stage, hope this helps :)
