The chemical energy that cells use to perform work is primarily derived from breaking the phosphate-phosphate bond in ATP.
<u>Answer:</u>
<em>less than 38 kilograms</em>
<u>Explanation:</u>
The weight of a body when measured on earth is the resultant force the ground applies to balance the force due to mass of the <em>body and acceleration due to gravity.</em>
Because your weight depends on the gravity you would weigh less on a planetary body with less gravity than on Earth, and in space you would weigh almost nothing at all. So the answer is <em>less than 38 kg</em>
It is <em>measured in Newtons (N)</em>. The weight of a person changes with varying gravity. As such the mass of the body varies through the universe irrespective of the <em>gravity and other external factor</em>. It is measured in kilograms.
The characteristics of life are
-Having cells
-Growing
-Responding to its enviornment
-Having DNA
-Consuming and or using energy
-Reproducing
-Maintaining homiostasis
Viruses are not considerd alive because they dind
-Have DNA
-Have cells
-Maintain homiostasis
-Consume energy
Answer:
Crossing over increases the genetic variation
Errors in crossover formation result in chromosomal rearrangements (duplications and deletions) and may also cause chromosome nondisjunction
Explanation:
Crossing over, also known as recombination, refers to the exchange of genetic material (DNA) between non-sister chromatids of homologous chromosomes during meiosis. Crossing over increases the genetic variation of the resulting gametes, allowing different genetic combinations to be passed from parents to offspring. Unequal crossing over is a type of error associated with chromosomal duplication and/or deletion events. Unequal crossing over occurs when homologous sequences are not paired precisely. Moreover, errors in crossing over may also cause chromosome nondisjunction, thereby leading to aneuploidies.
