Because their bodies tell them that they need more oxygen and so breathe faster, and try and get the oxygen their body requires and depends on.
Answer:
D Independent assortment occurs when chromosomes separate during meiosis and causes variations that can be beneficial or harmful to a species
Explanation:
During meiosis, the homologous chromosomes separate and segregate independently of each other. This process is referred to as 'independent assortment'. In consequence, different gene variants or 'alleles' localized in homologous chromosomes segregate independently of each other during gamete formation, thereby one particular gamete has an equal probability to carry either of these segregating alleles. Independent assortment generates genetic variation in the gametes, which can be beneficial or deleterious in a given environment.
Increase in urbanization will lead to increase in the number of people who are living in an urban area and it will also lead to increase in development in that area. The increase in development can come in form of construction of industries, which release large amount of waste products that pollute the air. This will lead to air pollution and reduce air quality. Development can also be in form of availability of electricity, that makes it possible for people to operate different electrical gadgets such as radio and television, which can result in noise pollution. Increase in the number of people who operate motor vehicles will also lead to increase in air pollution, which is caused by fossils fuel.
Answer:
Muscles contract rapidly to produce heat on a cold day.
Explanation:
Genetically modified (GM) foods are the ones came from organisms whose genetic material (DNA) are altered as they do not occur naturally. Food shortage, cost, variety can make people support the GM foods, while, religious beliefs, allergy, and worrying about the food can limit the support for these foods.
<h3>What are the characteristics of GM foods?</h3>
Genetically modified (GM) foods are those derived from organisms the ones genetic material (DNA) has been altered as they do not occur naturally.
Its characteristics are:
- More nutritious food.
- Less use of pesticides.
- Faster growing plants and animals.
- Disease- and drought-resistant plants.
As food shortage, cost, variety can make people support the GM foods, while, religious beliefs, allergy, and worrying about the food can limit the support for these foods.
Thus, the correct option is A.
