Answer:
Small uncharged polar molecules, such as H2O, also can diffuse through membranes, but larger uncharged polar molecules, such as glucose, cannot. Charged molecules, such as ions, are unable to diffuse through a phospholipid bilayer regardless of size; even H+ ions cannot cross a lipid bilayer by free diffusion.
Explanation:
<u>Answer:</u> The weight of the person above the surface of a planet is 635.83N.
<u>Explanation:</u>
To calculate the weight of a person, we use the formula:
....(1)
where,
w = weight of an object
m = mass of the person = 65kg
g = acceleration due to the gravity of the planet
For the calculation of weight, we need to first find the acceleration due to gravity and for that we use the formula:
where, g = acceleration due to gravity =
G = Universal gravitational constant =
M = mass of the planet =
r = distance of the person from the planet =
Putting values in above equation, we get:
Putting this value in equation 1, we get:
Hence, the weight of the person above the surface of a planet is 635.83N.
Answer:
Temporal partitioning or niche differentiation
Explanation:
Temporal partitioning refers to the variability in the competitive abilities of different species competing for the same resources based on varying conditions of the environment.
The environmental factors could be light, temperature, moisture, etc. Each species specializes in feeding within varied condition of one or more of the factors.
<em>In this case, both species are in competition but while the first species feeds during the day, the second species feeds during the night. Here, light and temperature probably plays a huge factor.</em>
Temporal partitioning is also known as niche differentiation, segregation, separation or niche partitioning.
