Answer:
the correct answers are C and D: "<em>Both partners are able to grow on substrates on which each would not be able to grow on their own</em>", and "<em>The fungi receive carbohydrates and, in some cases nitrogen, from the algae, while the algae gain a "home" that anchors them on the substrate</em>".
Explanation:
Lichens are the result of a symbiotic association between algae and a fungus. These two organisms must cooperate to survive in places under certain inhospitable conditions, where otherwise, they would not be able to survive by themselves. Algaes are the photosynthetic organisms that provide carbohydrates to fungus. These last ones, get the carbon and energy they need to grow, and in exchange, they protect the algae from dehydration and radiation, and they might also provide minerals for their survival. Algae can also get a way to get attached to the substrate. When instead of regular algae, there is a prokaryotic cyanobacterium, these can also supply with fix nitrogen to fungus, in the form of nitrogenous compounds.
A cell that can differentiate into all cell types of the adult organism is known as pluripotent. Such cells are called meristematic cells in higher plants and embryonic stem cells in animals, though some groups report the presence of adult pluripotent cells.
Answer:
The correct answer is option B. has a defective allele and normal phenotype.
Explanation:
Genetic carrier or the hereditary carrier is an organism or a person that has a recessive allele for a particular trait or character (generally mutation) but does not exhibit the trait or any character related to the trait.
The carriers are normal in the sex-linked characters in comparison to the autosomal traits. Females are generally the carrier for sex-linked characters and carry the allele to the next generation.
Thus, the correct answer is option B. has a defective allele and normal.
Genetic adaptability is very important to the survival and adaptability of any specie. This is because, in a diverse population, the possibility of finding individuals with the right genetic adaptability to the changing environment is higher, the population will have more possible adaptations.
Answer:
The measures which is taken by country need to prevent global warming are given below.
1) The government of the country should planted more trees because plants are only organisms which reduces the concentration of harmful gases which causes global warming.
2) Reduce the use of fossil fuels such as petrol, coal and methane gas.
3) Use solar energy instead of fuel for the production of electricity and other industrial products.
