A trait is a characteristic, such as color or size, that is inherited by an offspring from its parents. The genes that control a trait come in pairs, one gene from each parent. We represent these gene pairs by writing a combination of two letters. For example, if one parent contributes a gene for blue eyes (c), and other parent contributes a gene for brown eyes(C), then we write the offspring’s eye color trait as Cc. This combination, of the two genes that determine the trait, is called a genotype. If gene pair contains a dominant allele, the the offspring will show this dominant trait
Answer:
38 ATP
Explanation:
On complete oxidation of one molecule of glucose yields 38 ATP. Break up of energy production is given below:
- During glycolysis 2 ATP and 2 NADH is produced.
- During formation of Acetyl CoA, 2 NADH is produced.
- During Citric Acid Cycle, 2 ATP, 6 NADH, 2 FADH₂ are produced.
Finally during Electron transport chain, reduced coenzymes NADH and FADH₂ oxidised to release ATP. Each NADH produce 3ATP and each FADH₂ produces 2 ATP. Altogether 10 NADH is produced during entire process of cellular respiration which yield 30 ATP and 2 FADH₂ yields 4 ATP. Therefore, on complete oxidation of one molecule of glucose yields 38 ATP.
Thin, flexible barrier around a cell; regulates what enters and leaves the cell
- contains the cytoplasm (all interior cell organelles and the cytosol) - allowing the chemical reactions in the cell to occur
<span>- semipermeable (or selectively permeable) - allows certain substances in, keeps others out </span>
<span>- offers limited protection</span>
<h2>When too walk your dog you are using energy from the sunlight to power this activity</h2>
Explanation:
The ultimate source of energy in the ecosystem is the sun. When we take our dog for a walk, we are utilizing energy stored in our body that we obtained food. We must have obtained that from either plants or animals. The animal in turn must have obtained its food from plant. Plants are the organisms in the food chain who can convert the energy from the sun into the chemical energy. So, we can say that when we walk our dog we use energy from the sunlight to power this activity.
Answer:
None of the options provided is correct but some are close
Explanation:
One of the ways in which a cell maintain homeostasis is by regulating what goes in and out of the cell through the cell membrane (which is a semi-permeable barrier). The amount of water is highly regulated by the cell in this case so as to regulate osmosis (movement of water molecules from a region of higher concentration to a region of lower concentration). Other substances regulated are oxygen and carbon dioxide.
NOTE: The cell <u>does not create water molecules neither does it use carbon dioxide to maintain homeostasis</u>, it rather regulates these two compounds.
