Answer:
stages of the nitrogen cycle
1. Nitrogen-fixation
Legume plants such as peas, beans and clover contain nitrogen-fixing bacteria. These bacteria live in swellings in the plant roots called nodules. Nitrogen-fixing bacteria convert nitrogen gas from air into a form that plants can use to make proteins.
Free-living nitrogen-fixing bacteria are also found in the soil. When they die the nitrogen they have fixed into their biomass is converted into ammonium.
2. Feeding
Animals consume plant protein, digest it using specific enzymes and absorb the free amino acids.
3. Production of nitrogenous waste products
Animals cannot store excess protein in their bodies. They break it down and turn it into waste products and excrete them from their bodies.
4. Decomposition
Decomposers (some free-living bacteria and fungi) break down animal and plant proteins (from dead organisms) and nitrogenous waste products to release energy. As a result of decomposition nitrogen is released into the soil in the form of ammonium.
5. Nitrification
A group of free-living soil bacteria called nitrifying bacteria convert ammonium into nitrates in order to obtain energy.
6. Uptake of nitrates
Non-legume plants absorb nitrates from the soil into their roots and use the nitrates to produce their proteins.
7. Denitrification
This is when bacteria in the soil convert the nitrate back into nitrogen gas which then gets released back into the atmosphere.
Answer:
Catabolic processes break down material and transforms fuels into cellular energy, whereas anabolic processes require energy for biosynthesis.
Explanation:
Metabolism is a constructive and destructive process which occurs in the body of living organisms. There are two types of metabolism i. e. catabolism and anabolism. Catabolism is a destructive process in which food molecules are broken down into simpler substances for the production of energy while anabolism used this energy for the formation of new cells and muscles etc.
Answer:
1. Improvements in telecommunication
2. Improvements in global travel
Explanation:
Global culture refers to <u>the transmission of beliefs, values, and ideas around the world that has a significant impact in the behavior of society</u>. This has been evolving through time, especially since the Industrial Revolution. Today, we are capable of communicating with other people as quickly and easy as ever in the history of humanity and this will keep evolving as technology evolves as well.
This evolution is due to science and technology, especially to the improvements in telecommunication, which <u>enables us to communicate with people from other countries through calls, social media messagings, e-mails, etc.</u>, and to the improvements in global travel, which is <u>much more accessible today than it was before, allowing individuals to move from one country to the other easily and constantly and improving socialization between people from different cultures and backgrounds.</u>
In this question, the ant has 4 pairs of chromosomes. Each pair of chromosomes will be separated in a gamete, resulting 4 unpaired chromosomes. That is why gamete is called haploid or n.
That means only 1 of the 2 chromosomes that will be carried into a gamete, assuming the gene heterozygote then there would be 2 possibilities. Since each chromosome pairs can produce 2 possibilities for each male or female, their interaction will result as (2x2) 4 possibilities.
Then for 4 chromosomes would be 4^4 possibilities= 256 possibilities of offspring
