Answer:
B- Photosynthesis
Explanation:
Chloroplasts are <em>chlorophyll-containing, eukaryotic cell structures</em> that function in photosynthesis by absorbing energy from sunlight, combining this energy with water and CO2 to convert them to sugars . This cell structure is known as a plastid. The sugars produced, are important for the survival of the plant.
Chloroplasts reproduce on their own, independent of the whole cell because they contain their own DNA. Plant chloroplasts are located in guard cells in plant leaves. Closely linked to these guard cells are tiny pores called stomata, which allow gas exchange required for photosynthesis.
Photosynthesis occurs in two stages:
- The light reaction stage
- The dark reaction stage
The Light reaction stage takes place in the presence of light. Clorophyll converts light into chemical energy in the form of ATP and NADPH. Both molecules produced, are used in the dark stage to produce sugar.
In the dark reaction stage, the stroma, containing enzymes, facilitates reactions leading to the production of sugars from ATP and NADPH. This process is also called the carbon fixation stage. The sugar produced can be stored in the form of starch for other processes such as respiration.
Quick answer: Food enters the human digestive system through the mouth before then moving through the pharynx, esophagus, stomach, intestines, rectum and anus.
The small molecules that chain together to form a protein molecule are called amino acids an example of which could be glycine
Answer:
A) The resources used by both species of salamanders are available in limited supply
B) Body size is a heritable trait in salamanders Salamanders that are closer in body sine compete less strongly for food
C) The sympatric salamander populations evolved their present body sizes afterthey became sympatric
D) In sympatric populations, smaller P. Cinereus adults survive better and reproduce more.
All of the above are correct.
Explanation:
The gametes are genetically identical with the parent cell and with one another. The gametes have half the chromosomes of the parent cell, and are genetically identical with one another.
