Answer:
Here, should be the options to complete the question
1) Cells divide by constriction of a
ring of protein
2 The presence of a cell wall
prevents the cell from dividing by
constriction
3) Tubulin or tublin-like molecules
function in binary fission (in
bacteria) or cytokinesis (in animals
and plants)
Let's write out ANSWER
1) Cells divide by constriction of a
ring of protein
bacteria-true
animals-false
plant false
2 The presence of a cell wall
prevents the cell from dividing by
constriction
bacteria false
animal false
plant true
3) Tubulin or tublin-like molecules
function in binary fission (in
bacteria) or cytokinesis (in animals
and plants)
bacteria-true
animal false
plant-true
Answer:
Bottle neck effect
Explanation:
Bottle neck effect in Biology, refers to a phenomenon in which some environmental factors (droughts, disease, fires, floods, earthquakes or famine etc) or man made causes (like hunting) lead to a severe reduction in the size of population of a certain living organism.
This type of events not only lower the variation in the population genepool causing lack of genetic diversity, but also reduce the overall size of population.
The mentioned scenario in the question is an example of Bottleneck effect in which genetic diversity of the pigeon population was decreased due to man made activity i.e Hunting.
Hope it help!
Answer:
The walls observed were plant cell walls, that form the tissue.
Explanation:
Hooke's observation resulted in the discovery of the plant cells, which only began possible when the microscope was invented. As a result, Hooke defined the term "cell" to describe the "cavities" visible under the microscope.
I think it’s winter because the southern hemisphere is tilted away from the sun, if I’m looking at that right.
I'm working on the assignment rn. But here are some clues to help you.
