Answer:
Passive transport
Explanation:
Water is transported through channel proteins called aquaporins.
Answer:
The polar bear is an animal which is prevalent in the arctic region of the world which is characterized by very cold icy climate.
They adapt to these climatic conditions by maintaining a body temperature of 37°C through its thick fur and tough skin. It also has an insulating fat layer (adipose tissues) which is very thick.
This insulation helps in keeping the animal very warm in extreme temperatures.
<span> Eukaryotic cells are a lot more complex. They
have a nucleus in a nuclear membrane, where DNA or other genetic
information is stored, as well as lots of organelles that serve
different functions.</span>
Answer: In lab, we used Benedict's reagent to test for one particular reducing sugar: glucose. Benedict's reagent starts out aqua-blue. As it is heated in the presence of reducing sugars, it turns yellow to orange. The "hotter" the final color of the reagent, the higher the concentration of reducing sugar.
Answer:
Force = 78 N
Explanation:
Given data:
Mass = 39 Kg
Acceleration = 2 m/s²
Force generate = ?
Solution:
Formula:
F = ma
F = force
m = mass
a = acceleration
Now we will put the values.
F = 39 Kg × 2 m/s²
F = 78 Kg.m/s²
Kg.m/s² = N
F = 78 N
