Answer:
B
Explanation:
We never see short bristle males, suggesting some type of lethality. I.e. any males who inherit the mutation die before birth so we don't see the phenotype. This also hints that it could be X-linked.
Females can be short bristled, but males can't, as it is likely lethal. This suggests that having one copy of the short bristle trait without the long bristle trait is lethal (as males as XY and so only have one copy of the trait). The female then must be heterozygous for the short bristle trait (which also explains how in generation F2, long bristle males can be produced, as if she was homozygous males would all be short bristled, and therefore dead, so there would be no males.
Since the first short bristle female is heterozygous, the trait for short bristles must be dominant.
However, since evidence suggests the trait is X-linked, it cannot be autosomal, as suggested in B.
Answer:
experiments can be designed and performed by anyone with a curious mind
Explanation:
baking soda and vinegar explosions are an experiment that doesnt require expensive equipment
always do more then one trial, like shooting a basketball, if you shoot once and miss, can you say that you will never make it? or if you make it, can you say that you will never miss?
variables are what you are testing, you have to eliminate as many as possible so they dont effect your experiment
if you have any questions, leave them in the coments and i will try to answer them, if this helped, pls give brainliest.

Answer and Explanation:
Invasive species are not native to an ecosystem/environment to which they've been introduced, which can cause disastrous disruptions to various food chains/webs and other native species' populations.
In this case, your cousin is bringing in a plant from overseas, so it clearly will be an invasive plant. You can tell them the following:
- this plant may take over the feeding source of native plants, causing those populations to decrease drastically or possibly even be wiped out
- secondary consumers that had once relied on those native plants for food energy will now have limited resources, competition will increase, and these consumers may begin to die off
- tertiary consumers that consumed these secondary consumers will begin to die off, as well
- this chain reaction will ripple through the entire food chain and food web, and totally disrupt the existing ecosystem
Thus, your cousin shouldn't plant this organism in their backyard and should instead destroy it.
