You need to do speed divided by time
The best answer is B.
The endosymbiotic theory states that mitochondria and chloroplasts have striking similarities to bacterial cells:
1. they have their own DNA, which is separate from the DNA found in the nucleus of the cell.
2. Both organelles use their DNA for to produce many proteins and enzymes required for function.
3. They are both surrounded by a double membrane.
4. They reproduce just the way bacteria do, replicating their own DNA and directing their own division.
<h2>Energy allocation in penguin</h2>
Explanation:
- Although penguins don't grow from year to year, they increase and decrease in size as they repeatedly form and use energy stores,a significant amount of energy might be stored in fat during part of the year but be missing from the pie chart because it is used later in the year
- Allocation of limited endogenous resources causes trade-offs between competing traits, such as reproduction, somatic growth and maintenance
- During food deprivation, animals cannot maximize all of their life-history traits and must exhibit adaptive behavioral, physiological and biochemical responses to reduce metabolism and/or the cost of current activities in order to maintain biological value
Answer:
A
Explanation:
The earth is tilted at an average of 23.5 degrees. This means that in some seasons, the north pole is tilted towards the sun and in some seasons it is tilted away from the sun. The sun seems to vary in position over an year as the earth revolves around the star. The sun, therefore, variably and differentially heats the regions of the earth. The regions that are heated more form low-pressure system that drives winds.
