<h2>Cellular respiration </h2>
Explanation:
- Cellular respiration is defined as a ATP generating process in which organic molecule is oxidized and inorganic molecule is final electron acceptor
- Pain experienced in leg muscles is the result of formation of lactic acid in muscle cells
- Under low oxygen, NADH cannot be reoxidized to NAD+ but NAD+ is required as an electron acceptor to continue glycolysis
- In lactic acid fermentation pyruvate is the final electron acceptor and converted in lactate
- Reaction catalyzed by lactate dehydrogenase
- The pain in her chest is caused from the lack of oxygen she received while running so her chest starts to heavily breathe so that the lungs can receive as much oxygen possible
If there is limited of food then they will compete but if there is an equal amount of food they won’t compete. So the answer is true.
Answer and Explanation:
A gene is a section of DNA. The change in the sequence of the DNA is known as mutation. Mutation always changes the sequence of the DNA. Sunlight can cause mutation. Sunlight produces structures named thymine dimers. Thymine dimers produce twist in the shape of DNA. These twists make DNA hard to copy, which can lead to mutation. It is essential to use sunscreen to block UVA and UVB rays to prevent thymine dimers from emerging in our cells. The US Food and Drug Agency recommends an SPF (sun protection factor) to defend against skin aging and skin cancer. X-ray radiation is a form used in x-rays. The energy level of the X-ray radiation is very high that can produce free radicals. Free radicals can steal electrons from DNA that can cause mutation. By using medical images, we can decrease exposure to X-rays. Less exposure to X-rays prevents mutation and also prevents the production of gene protein in other body parts.
Answer:
Apply the principle of parsimony
Explanation:
A cladogram is used to show or illustrate hypothetical speciation and relationships between species. They are commonly used to classify animals.
The principle of parsimony argues that the simplest of competing explanations is most likely to be correct.
In order to construct a cladogram that best reflects the evolutionary relationship of a group of species. Application of the principle of parsimony will help in deciding which tree is most likely to have occurred based on the fewest character state changes.
The organisms which appeared on earth first was bacteria.
<u>Explanation:</u>
- The first-ever living organism on Earth was a bacteria known as cyanobacteria. It is believed by scientists that it first formed around 3 billion years ago.
- When the Earth was first formed, it was inhospitable for a long time until 3.8 billion years ago approximately, the core cooled down and the level of oxygen had risen. This, along with photosynthesis resulted in the formation of Cyanobacteria.
- These organisms were capable of carrying out the process of photosynthesis by which they prepared their food. These were known as common ancestors. All the living organisms thereafter are known to be their descendants.
