A desert plant called Kalanchoe can reproduce, either with sexual reproduction through flowers, or asexually by budding off mini
AnnyKZ [126]

Answer:

The correct answer will be- will be called "Clones" with no genetic variation thus result in less adaptability to environment.

Explanation:

Plants can reproduce by both modes of reproduction called asexual and sexual reproduction.   The asexual mode of reproduction produces genetically similar offsprings in less period of time and thus helps in spreading of the species in minimum time as in the case of Kalanchoe.

The Kalanchoe can dominate a large area of the habitat using this mode of reproduction but at the cost of genetic variation.  

Since asexual reproduction results in Clones with same genetic material so the descendants of the plant will be less adaptive to changing the environment as asexual reproduction does not involve genes.

Which of the following best explains why herring gull chicks were one of the first species to exhibit the effects of pollution,
prohojiy [21]
The correct answer is A.
Toxins and various pollutants increase in concentration through the food chain in a process called biomagnification. This means that the organisms on the top of the food chain, like the herring gull, have many times greater concentration of toxins than the lower food chain level organisms because they prey on lower food chain level organisms. If a herring gull ears 100 herrings, it will have a 100x times greater concentration of toxins in its body than a herring.

Inessa05 [86]

Answer:

intrinsic

Explanation:

Proteins are dynamic molecules that are capable of INTRINSIC motion that can have important functional relevance. The existence of this type of motion has suggested that enzymes are capable - even in the absence of substrate - of many of the same movements that can be detected during their catalytic cycle

A Venus flytrap closes around a small insect. Which life characteristic does this illustrate? A. reproduction B. response to sti
Mnenie [13.5K]
The answer is B: Response to stimuli
what response to stimuli means is that the organism reacts to something around it
the venus flytrap wouldn't just randomly close for no reason
it had to sense the fly, and react by closing.

it's not permeability because permeability means allowing things to pass through like soaking up water
unless your teacher is referring to absorbing the nutrients of the dead fly after it's been killed
but I don't think that's what this question is about
:)
