which is one major difference between anaerobic and aerobic respiration?

Answers

Answer:

the anaerobic is a different form

One major difference between anaerobic and aerobic respiration is the electron acceptor. The correct option is b.

What is aerobic respiration?

Aerobic respiration occurs in a cell when glucose is broken down with the help of oxygen to produce carbon dioxide, water, and the release of energy. For instance, aerobic respiration occurs in mitochondria.

Anaerobic respiration, on the other hand, is the breakdown of glucose without the use of oxygen in a cell, producing alcohol, carbon dioxide, and the release of energy. Yeasts, for instance, breathe anaerobically.

We can therefore draw the conclusion that the primary distinction between aerobic and anaerobic respiration is that the former requires oxygen while the latter does not.

Therefore, the correct option is b, electron acceptor.

In terms of numbers of births and deaths, explain in detail why human population is growing so tremendously.

Answers

The human population is growling due to an interplay of many factors.

Why is human population is growing so tremendously in terms of numbers of births and deaths?

The human population is growing so tremendously in terms of numbers of births and deaths due to several factors, including:

Improved healthcare: Advances in medical technology and healthcare have led to a significant decrease in mortality rates, particularly in developing countries. This has resulted in more people surviving diseases and living longer lives.

Increased food production: Improved agricultural practices and technology have increased food production, resulting in more food being available to feed the growing population.

Higher fertility rates: Although fertility rates have declined in some countries, they remain high in many developing countries due to cultural and social factors, lack of access to family planning, and limited education and economic opportunities for women.

Urbanization: As people move from rural areas to cities, they tend to have smaller families, but the overall population continues to grow due to the influx of people into urban areas.

Overall, the growth of the human population is a complex issue that is influenced by a variety of social, economic, and environmental factors. It is important to address these factors to ensure that population growth is sustainable and does not result in negative consequences such as overconsumption of resources and environmental degradation.

An investigator wishes to use animals in an experiment that involves category B, C, and D activities performed on the same animal. How should the animal be categorized

Answers

Answer:

Category D

Explanation:

In the USA, the Federal Animal Welfare Regulations require that research laboratories report animal use according to the species as well as the number of individuals subject to experimentation procedures. Moreover, animal use for research/teaching purposes is also reported according to the classification by pain and distress categories. Basically, this classification has four categories (B,C, D and E) in increasing order according to the pain level suffered by research animals. Animals within Category D include those subjected to potentially painful or stressful procedures. In consequence, in this category, it is imperative the utilization of proper anesthetics and/or analgesics in order to diminish the pain and suffering of these animals at the lower level possible.
