Answer:
At the end of 6 hours, 6 feet of the ladder remained above water
Explanation:
we are given the following:
change in tide = 8 inches per hour
1 hour = 8 inches
∴ 6 hours = 8 × 6 = 48 inches
Now, since the length of the ladder is measured in foot, let us convert the rate of tide rising to foot.
12 inches = 1 foot
dividing both sides by 12:
Therefore, after 6 hours, the tide rises by 2 feet.
Next, we are told that the rope ladder at the beginning was 8 feet, hence the length remaining above water after 6 hours of the rising of the tide is calculated as follows:
= 8 feet above water
height of tide = 2 feet = amount submerged in water
∴ length above water = (ladder before rising of the tide) - (amount submerged in water)
length above water = 8 - 2 = 6 feet
Therefore at the end of 6 hours, 6 feet of the ladder remained above water
Hello!
Could be either:
<span>The action or process of observing something or someone carefully or in order to gain information.
</span>
Or
<span>A remark, statement, or comment based on something one has seen, heard, or noticed.
</span>
And in Science:
<span>An 'observation' in the scientific sense, is when you make a measurement or evaluation of some sort. You would usually make a note of how something has changed sine the previous ovbservation. Maybe the temperature has changed: gone up one degree; or a crystal has grown: maybe it is now .1 centimeters longer.
"Observations" usually implies that you are watching some process, and either measuring or noting the change that has taken place. usually you will also want to note the time of the observation, so that you can have an idea of how quickly (or slowly) the changes are occurring.

Hope this All Helps (Hope it did)! Have A Wonderful Day! :)
Answer:
When homologous chromosomes form pairs during prophase I of meiosis I, crossing-over can occur. Crossing-over is the exchange of genetic material between homologous chromosomes. It results in new combinations of genes on each chromosome. It is obviously another source of genetic variation in offspring.
Hope this helps you. Do mark me as brainliest.
Answer:
The correct answer will be option-accurate and complete DNA replication.
Explanation:
The cell cycle of a cell is controlled by the internal checkpoints where the cell cycle halts until the favourable conditions appear. These checkpoints are G1 checkpoint, G2 checkpoint and M checkpoint.
The G2 checkpoint asses that the DNA replication has been completed, all the chromosomes have been replicated and the replicated DNA is not damaged. The cell cycle stops if the replicated DNA is found damaged.
Thus, option-accurate and complete DNA is the correct answer.
The answer is C) Cloning eliminates the ability to sexually reproduce and provide genetic variability.
In the future, there is no variability in the genes in the clones given that they are the exact copies of the "parent" produce. All should be identical without differences and variations. Although Farmer Brown doesn't want this to happen that's is what he is reluctant to listen to Farmer Green's advice.
