A) Homozygous
An organism in which two copies of the gene are identical and are the same allele is called homozygous
<u>Answer:</u>
Although statements are not given in the question, we could make the most possible deduction as follows:
The allele for purple flowers is dominant whereas allele for white flowers is recessive.
<u>Explanation:</u>
According to the question,
- Purple flower plant was crossed with white flower plant.
- All offsprings have purple flowers.
Here we have one possibility that both parents were homozygous but in their own traits. <u>Purple flower</u> plants were "PP" and white <u>flower plants</u> were "pp" So, the <u>first progeny</u> (direct offsprings) would have "Pp". So, as per considerations, purple is dominant allele which will mask the recessive allele thus defining the color of all offsprings as purple. However, further cross of their generation will definitely end up into purple and white flowers (3:1) but this condition is not mentioned in the statement.
Smoking ruins your lungs making it harder to breath and get oxygen
you need oxygen when you exercise so you don't faint
smokers get less so it is harder for them, its like trying to exercise while breathing through a sponge or a straw os
<h2>J-shaped growth curve</h2>
Explanation:
- J- shaped growth curve A curve on a graph that records the circumstance wherein, in another condition, the population thickness of a living being increments quickly in an exponential or logarithmic structure, yet then stops unexpectedly as ecological opposition (for example regularity) or some other factor (for example the finish of the reproducing stage) unexpectedly gets compelling.
- Population numbers regularly show extraordinary variance, giving the trademark 'blast and bust' patterns of certain bugs, or the ones seen in algal sprouts.
- This kind of population development is named 'thickness autonomous' as the guideline of development rate isn't attached to the population thickness until the last accident
Answer:
As the spies of a cactus are modified leaves, they have ar spaces.
Explanation:
However, leaves of cactus are not like every other leaf. These leaves are in the form of spines to save the amount of water that the cactus needs.
Most of the amount of water, cactus s saving in its root. Also, the stem of a cactus is used for making food, and this is also the way of saving the water.
