Answer:
B) Air Resistance
Explanation:
A reaction force is the opposite of an action force, so what is opposing gravity? Momentum certainly isn't in this instance of the apple falling. Thermal velocity isn't, and anti gravity is a hypothetical phenomenon.
Answer;
Heterozygote advantage occurs when heterozygotes have a higher fitness than do both homozygotes. In frequency-dependant selection, the fitness of a phenotype declines it it becomes too common in the population.
Explanation;
The heterozygotes have both alleles, which is needed for genetic variation. Heterozygotes are essential for there to be genetic variation in a population. In other words it is when When a single copy of a disease allele doesn't result in a disease but instead is good for the person or organism that carries it, we say that allele has a heterozygote advantage. For example a sickle cell trait, which protects against malaria in heterozygotes, but causes a deadly disease in homozygotes.
-Frequency-dependent selection occurs when the fitness of a genotype depends on its frequency. It is possible for the fitness of a genotype to increase (positively frequency-dependent) or decrease (negatively frequency-dependent) as the genotype frequency in the population increases.
Answer:
The correct answer will be option-C
Explanation:
The genome size is the total amount of DNA present in the organisms which includes both coding and non-coding sequences. The genome size is measured in the C-value.
The gene complexity is the complexity in the DNA of an organism which arises due to gene duplication and other mechanisms.
The gene complexity does not show correlation with the size of the organisms which is expected that the larger eukaryotes will have a larger genome size. This is known as the C-value Paradox.
In the given question, since the yeast contains 13 MB, Humans contains only 2,900 Mb whereas a plant of Lily family contains about 120,000 Mb which shows that the lily should be the largest eukaryote which is not the case.
Thus, Option-C is the correct answer.
Answer: Nuclear membrane
Explanation:
The extracellular matrix can be defined as the matrix that lies outside the cell. It includes all membranes or external coverings and fluid which separates the cell from its exterior. The extracellular matrix is important for adhesion, and communication between cell to cell. This helps the cell to connect with the other substratum. The cell wall is the external layer around the plant cell which separates the plant cell from its external environment. It maintains the structure of the plant cell. The cuticle is the thick layer of cells which separates the cells from the external environment. The basement membrane is sheet of cells that forms the part of extracellular matrix in the epidermis. The nuclear membrane is the part of the cell. It lies around the nucleus which is the component of the cell and not of extracellular matrix.
