Answer:
S phase
Explanation:
S phase is the second phase of interphase (longest phase where cell grows and replicates it's DNA and does it function. It is broken up into smaller sub phases). S phase is the synthesis phase. During this phase chromosomes are replicated ( The DNA is copied).
Answer:
Out of two objects the one with ratio of surface area to volume equal 2.2 m-1 will have higher diffusion rate and hence will take less time in a diffusion test
Explanation:
As we all know, that rate of diffusion is linked to the surface area--to--volume ratio. Larger surface area--to--volume ratio depicts that the surface area of an object is higher that than of its volume. The higher surface area provides higher area for diffusion.
Thus, any smaller object with larger surface area--to--volume ratio will provide higher diffusion rate and hence the time for diffusion will decrease.
While any object with smaller surface area--to--volume ratio will provide lower diffusion rate and hence the time for diffusion will increase.
Thus, out of two objects the one with ratio of surface area to volume equal 2.2 m-1 will have higher diffusion rate and hence will take less time in a diffusion test
A descriptive observation may very well be a mixture of both quantitative and qualitative as it can utilize elements of both types. Qualitative deals with the kinds of observations that cannot be measured in numerical form. Quantitative data is just that.
Answer:
In the short term, what we would call “ecological time scales”, competition shapes communities primarily by limiting population growth. Every population requires and excess of required resources to grow larger, but if another population is taking those resources instead, then their growth is limited. If your competitor is significantly better at securing resources, and is growing larger, your population may find that it is actually too large for the amount of resources it is capable of obtaining, and so will have to shrink down to a level that can be sustained by the amount of resources it can get.
Competition with individuals of your own species also limits the size of your population, even more so than competition with other species. This is because members of the same species have more overlapping sets of resources that they require. Two humans both need houses and water, so they compete for them both, but they don’t have to compete with birds for houses, only water.
In the longer term, called “evolutionary time scales”, competition can change the characteristics of the species that are in competition with each other. Species may evolve to need certain resources less if their competitors are better at obtaining them. This allows those two species to evolve to be more compatible, allowing them to better coexist by making them less competitive with one another.
Evolution won’t change a single species to be able to compete less with members of its own species, but in some cases it can lead to the creation of new species.
