The bird's eye contains a nictitating membrane which is a translucent, semitransparent inner eyelid. It sweeps across the surface of the eye enabling the bird to blink without losing sight of or without blocking their view.
Birds also have two different tear glands. One type of tear gland is located along the lower eyelid while the other is located at the base of the nictitating membrane. The second tear gland lubricates the bird's eyes whenever the nictitating membrane blinks.
Answer:
1 out of 4
or
25%
Explanation:
First we draw a Punnett Square for this:
R r
R RR Rr
r Rr rr
So here we have the following genotypes possible for this cross:
RR = homozygous dominant
Rr = heterozygous dominant
rr = homozygous recessive
As you can see out of the four (4) possible outcomes, one (1) of them is rr. So the probability is 1 out of 4 chances or 25%.
There would be 18 oxygen atoms total in CO2 and H2O.
2 oxygen atoms per CO2, times 6 because there are six CO2 molecules, plus 6 times 1 oxygen atom in H2O.
In order to calculate the work done, you need to know how far she lifted it. We don't know the distance, so it's not possible to calculate the work.
All we have right now is a laundry basket that weighs 75N being lifted with 100N of force. Reading carefully, we know that the vertical forces on the laundry basket are unbalanced, and the NET force on it is 25N upward.
We can go further if we assume that all of this is happening on Earth. Then, since the basket's weight is 75N, its mass is (W/g) = 7.653 kg. From Newton #2, we know that F=mA, which we can re-arrange to state that A = F/m. So in the case of the unfortunate laundry basket,
A = F/m = (25N / 7.653 kg) = <em>3.27 m/s²</em> .
The laundry basket is accelerating to the sky as we speak, at the rate of 3.27 meters per second². As it cleared the fence a few moments ago, Mrs. O'Leary's cows next door spotted it, panicked, ran into the barn and clear through the back wall into the pasture. Now, a full minute after lift-off, the laundry basket has achieved a vertical velocity 196 m/s, and is 5.88 kilometers downrange. After a simple roll maneuver, it may be in orbit soon, if the 100N force on it continues.
Answer:
Explanation:
The hypothesis is supported by the studies on mitochondria. The mitochondria contains its own DNA and sythesizes many of its RNA and proteins. The mitochondrial protein synthesis machine, the ribosomes are similar to those found in bacteria. Similar to the bacterial cells, the mitochondria also contain circular genome
