Answer:
offspring
Explanation:
A dominant allele is denoted by a capital letter (A versus a). Since each parent provides one allele, the possible combinations are: AA, Aa, and aa. Offspring whose genotype is either AA or Aa will have the dominant trait expressed phenotypically, while aa individuals express the recessive trait.
Answer:
Carbon dioxide and water; organic molecules and oxygen; chemical potential; usable chemical energy in the form of ATP; heat energy that cannot do work
<u>Explanation</u>:
- Cellular respiration produces <u>carbon dioxide and water</u> from <u>organic molecules and oxygen</u>; organic molecules are a source of <u>chemical potential energy</u> that cellular respiration transfers into <u>usable chemical energy in the form of ATP</u> and transforms into <u>heat energy that cannot do work</u>.
- <u><em>Cellular respiration</em></u> is a process that takes place in the mitochondria in living organisms cells. It is the powerhouse of a cell.
- <em><u>The process involves the break down of organic molecules such as glucose, in presence of oxygen, to generate energy in the form of ATP, which is the usable form of energy by the cells to drive processes such as transport, growth and development, etc.</u></em>
- The process converts chemical potential energy in organic compounds to usable chemical energy in the form of ATP. Carbon dioxide and water are also produced as by-products during the process.
Answer:
The oceans shape landforms around the globe. As the ocean
tides rise and fall twice daily, they erode soil from beaches,
melt ice from glaciers, and move sediment around which
creates shifting sand bars. The sizes and shapes of the land
affect the surfaces of Earth that are heated by the Sun,
therefore creating changing weather patterns.
The water in your shower could have come from anywhere in
the world because all of Earth’s water is recycled in a process
called the water cycle. Just how does water from a glacier
halfway around the world find its way to your bathroom?

Explanation:
Answer:
An advantageous allele might be dominant or recessive in population. In case of dominant advantageous allele the dynamics is relatively simple because being dominant the allele is expressed both in homozygous and heterozygous condition. Combined with the advantage of natural selection, its frequency increases rapidly.
However, recessive advantageous allele does not increase rapidly because despite being advantageous it gets masked by the dominant allele. When it is rare, it is present in very less number of recessive homozygotes and in slightly more number as heterozygotes. Over the generations, natural selection selects the recessive allele so the number of heterozygotes start to increase slowly. Recessive homozygotes are still rare because they need both the copies of recessive allele. Eventually recessive homozygotes also start increasing in number which leads to the fixation of recessive allele in the population.
