Answer:
Deoxyribose and phosphate
Explanation:
The other molecule of the sides that lies in between sugar are deoxyribose and phosphate. The sugar has the nitrogenous based molecule attached to it.
Answer:
Quadrat sampling is a method by which organisms in a certain proportion of the. habitat are counted directly. It is used to estimate population abundance, density, frequency and. distribution. The quadrat position are chosen randomly or they are placed along a transect.
Explanation:
Answer:
D) Ciliated simple columnar epithelium
Answer:
D. Mutually beneficial: the bee receives pollen and the flower gets help with its reproduction
Explanation:
It is a mutually beneficial relationship because the flower provides the bee with nectar and pollen. Also, the bee provides the flower with a means to reproduce by spreading pollen from flower to flower through pollination.
Answer:
When the patch occupancy rate (c) equals the patch extinction rate (e), patch occupancy (P) is 0
Explanation:
According to Levin's model (1969):
<em>dP/dt = c - e</em>
where P represents the proportion of occupied patches.
<em>c</em><em> </em>and <em>e </em>are the local immigration and extinction probabilities per patch.
Thus, the rate of change of P, written as dP/dt, tells you whether P will increase, decrease or stay the same:
- if dP/dt >0, then P is increasing with time
- if dP/dt <0, then P is decreasing with time
- if dP/dt = 0, then P is remaining the same with time.
The rate dP/dt is calculated by the difference between colonization or occupancy rate (<em>c</em>) and extinction rate (<em>e</em>).
c is then calculated as the number of successful colonizations of unoccupied patches as a proportion of all available patches, while e is the proportion of patches becoming empty. Notice that P can range between 0 and 1.
As a result, if the patch occupancy rate (c) equals the patch extinction rate (e), then patch occupancy P equals to 0.
