Answer: Option B) Nucleus
A threadlike genetic material called chromatin is located within the nucleus
Explanation:
Chromosomes are thread-like genetic materials that exist in pairs. However, they are called chromatid when single. Hence, two chromatids makes a chromosome. And chromosomes are located within the nucleus
Answer:deoxyribose
Explanation: From the information provided, (though the diagram is not shown), the structure is a DNA double helix. A DNA contains deoxyribose sugar thus the name deoxyribonucleic acid. RNAs contains ribose sugar thus the name ribonucleic acid. A deoxyribose is a pentose (a 5- carbon sugar) which lacks one oxygen atom at position two of its carbon skeleton, hence the name deoxy - ribose. It's usually written chemically as 2- deoxyribose.
Answer:
Bioremediation
Biological augmentation
Biodiversity expansion
Pollution cleanup
Explanation:
Biological augmentation is the method where plastics eating fungus are sent to landfills.
Answer:
Biodiversity is usually defined as the diversification of living species that exist on earth and the complexities that occurs in the ecosystem. It includes all the plants, animals, humans and micro-organisms.
The biodiversity is often affected by factors such as climate change, loss of habitat area, and occurrence of invasive species.
Three of the biological services that are provided by biodiversity are as follows-
- A large number of medicines are being made from the various plant species that exist in an ecosystem.
- It provides food, on which the organisms are dependent on it.
- It also provides materials that are used for construction purpose and used as shelter.
I will answer the question accordingly so that it help you under stand it better.
Question A.
During an extreme heat wave, plants with white flowers survive better.
What mechanism is in work here?
Answer: Mechanism of Natural Selection
will work here. This is called survival of the fittest which means the best color which fits in harsh conditions will dominate over others and will survive for longer time.
What is the effect on the gene pool?
Answer: The Frequency of white allele will increases
because white color is the best fit to extreme heat wave.
Question B.
A person uproots the five closest plants, which all happen to have white flowers.
What mechanism is in work here?
Answer: The mechanism of gene flow will work here as color of flower represents genotype of flower.
What is the effect on the gene pool?
Answer: The Frequency of white allele will increases because genotype of white flowers is increased.
