Answer: Option E) Ultraviolet radiation - dessication is the mismatched pair
Explanation: Ultraviolet radiation when it falls on certain materials does not lead to dessication ( dessication means removal of water from materials) but it causes those materials to emit electromagnetic radiation of lower energy.
Answer:
The difference between the microfilaments, intermediate filaments, and microtubules are stated below.
Explanation:
- They are made up of two chains made up of monomeric globular proteins called actin. The chains are coiled around each other.
- They have a diameter of about 7 nanometre.
- They help in cellular movement.
- They form strands which are made up of fibrous proteins like keratin, vimentin, desmin.
- They have a diameter which ranges from 8 nanometre to 10 nanometre.
- They have structural function and are required to maintain the cell shape and organelle position.
- They are formed when the globular proteins, alpha-tubulin and beta-tubulin form dimer and undergo polymerisation.
- They have a diameter of about 25 nanometre.
- They form the structural components of flagella, cilia and centrioles. They prevent cell compression.
Answer:
Underwater plants will receive less light.
Explanation:
When sea level rises the amount of solar energy in the aquatic environment is decreased and this makes underwater plants receive less light and their development is impaired. This is because, with less sunlight, aquatic plants are unable to photosynthesize and absorb the carbon needed for their metabolism, thus end up dying and diminishing the plant diversity of the sub-aquatic environment.
In addition, many underwater organisms (such as some fish) feed exclusively on these plants. If these plants fail to grow, these fish will be without food and will eventually die; This will also cause problems for the diversity of the underwater environment.
Answer:
In the dominant- recessive model of inheritance, the dominant allele fully suppresses the recessive allele. As a result, heterozygous individuals produced show the effect of the dominant trait in them. For the recessive trait to occur, both the alleles of the gene should be recessive in the organism.
In co- dominance model of inheritance, the dominant allele is not fully dominant over the recessive trait. As a result, heterozygous individuals show both the dominant and recessive characteristic in them. For a dominant trait to occur, both the alleles should be dominant. For a recessive trait to occur, both the alleles should be recessive.
The answer is Progestins. Some of numerous artificial progestational constituents that mimic some or all of the engagements of progesterone which is used as contraceptives one or the other single-handedly or in group with estrogen and with estrogen in hormone added therapy and in addition, it is female hormone like progesterone that turns on the inner lining of the uterus.
