Answer:
A. anaerobic respiration in muscle cells, forming lactic acid
Explanation:
Running marathon is a vigorous exercise, which often leads to excessive use of oxygen in the cells of the athlete. This causes the cells to switch from the aerobic (with oxygen) to the anaerobic (without oxygen) mode of respiration. This anaerobic respiration produces a product called LACTATE OR LACTIC ACID.
The lactic acid becomes excessive and gets stored in the muscle cells of the athlete. This often leads to cramps, muscle pulls etc. during the marathon. Therefore, an individual running a marathon may experience periods of oxygen deprivation that can lead to anaerobic respiration in muscle cells, forming lactic acid.
<span>Answer: Biodiversity</span>
The suppression of forest fires causes a decrease in biodiversity because
some habitats require exposure to fire. Most ecosystems of savanna, chaparral
and coniferous forests have developed with fire as an essential contributor to habitat’s vigor
and regeneration.
Additionally, wildfire suppression eliminates plant species
in fire-affected environments that require fire to germinate, established, or to
reproduce. Also, animals that depend on these plants will be affected too.
Plants are in the ground with soil
Answer:
1
Explanation:
An organ is a structure that is composed of at least two or more tissue types and performs a specific set of functions for the body.
Answer:
The correct matches are given as follows:
a. Amylase
- Starch
b. Pepsin
- Protein
c. Lipase- fats
Explanation:
The digestion can be defined as the breaking down of the complex compounds of food into simpler compounds for their better absorption. There are various enzyme that help in the process of digestion. Amylase, pepsin, and lipase are enzymes. The amylase is an enzyme responsible for breakdown of starch. The pepsin is responsible for the breakdown of protein into amino acids. The lipase is responsible for breakdown of fats.
