Answer: b. False
Many mammals rests for a large proportion of the 24 hour. The rest period usually extent during hibernation. The marine mammals tend to rest or sleep with only one hemisphere is kept at rest. It allows them to keep one eye open this allows them to stay alert against the predators. But the terrestrial or land mammals when take rest both the hemispheres of the brain sleep.
On the basis of the above description, most land mammals have the ability to rest one hemisphere of their brains at a time is false.
b. it was washed by rain into streams, rivers, lakes, and ponds.
c. it was ingested by fish and other aquatic animals.
d. all of the above. please select the best answer from the choices provided a b c d
B. a three-nucleotide sequence.
C. a four-nucleotide sequence.
D. a five-nucleotide sequence.
-0.38 N
-57 N
-580 N
The answer is.57N.
Centripetal force (F) is a force that makes a body move around a circular curve. The unit of force is N (N = kg * m/s²).
It can be represented as:
where:
m - mass
v - velocity
r - radius of the curve
We have:
m = 38 kg
v = 6 m/s
r = 24 m
We need centripetal force:
N = ?
If:
Then:
Therefore, centripetal force child experiences during skating on
a circular track is 57 N.In order to solve the problem presented above you will simply need to use the formula shown below. Please see attachment. Now all we have to do is simply replace the variables with the information that the problem gives us. If we do that we will get the following:
F = m*v²/r
F = 38*6²/r
F = 38*36/24
F = 57 Newtons
I hope it helps, Regards.
Answer:
photosynthesis
Explanation:
Chlorophyll a absorbs the wavelengths of violet-blue and orange-red light and functions as a primary electron donor during the election transport chain in photosynthesis. It also functions in transporting energy to the reaction center where P680 and P700 are located.
Answer: The correct answer for the blank is -
Sepal, petal, stamen, and pistil.
Flower is the reproductive structure of flowering plants (angisperms). It is primarily composed of four parts, which are (from outside to innerside) -
Sepals (that together form calyx, the outermost protective whorl)
Petals (that together form corolla, the second whorl)
Stamen (the male reproductive part that together forms androecium, which is the male reproductive organ).
Stamen is further composed of anther (that produces pollen) and filament (stalk like structure, which protects anther).
Pistil (the innermost part that forms gynoecium, which is the female reproductive organ). It is composed of stigma, style, and ovary.
B) Crossing-over during meiosis
C) Neutral mutation during transcription
D) Genetic drift during reproduction
