Answer:
Phagocytosis is a type of endocytosis performed by phacytes. Bacteria is engulfed through phagocytosis (part of the cell membrane surrounds the bacteria inside the cell). Then lysosomes fuse with the phagosome and the bacteria is digested. After digestion, the cell perform exocytosis of waste products.
Theres a character minimum smh but i think its d pls check though g00gle is fr33
Answer:
3:1
Explanation:
Let the allele for tall plant be T; &
The allele for short plant be t
When Mendel crossed true-breeding tall pea plants(i.e TT) with true-breeding short pea plants(I.e tt); all the offspring were tall.
TT × tt
T T
t Tt Tt
t Tt Tt
we can deduce from the punnet square that the F1 offspring are all heterozygous tall plant.
Now, if the first generation (F1) tall plants are allowed to self-pollinate; we have a cross between Tt and Tt
TT × tt
T t
T TT Tt
t Tt tt
We can see phenotypically that we have 3 tall plant(TT,Tt, Tt) and 1 short plant(tt).
Therefore the ratio of phenotypes he expected in the F2 generation is (3:1)
I believe your stance on mutation is in needs to be re-evaluated. The articles I’ve been reading say that mutations are either harmful or neutral. There are, however, such things as beneficial mutations. For example, there are people with mutations in the CCR5 gene that make them virtually immune to HIV. There are also a class of cancer drugs that are 100% effective, but only in a minority of individuals that have a certain mutation. Both of these mutations could seriously improve a person’s chance of survival. I therefore fail to see what makes you think all mutations are bad?
Answer:
A hypothesis is a scientific guess.
Explanation:
So a scientific question, is something either related to your hypothesis or the experiment you are doing. (Hope this somewhat helps!)
