Explanation:
This statement is correct because the concept of integrating body and mind in physical activity was responsible for the expansion of physical activity, in addition to activities that promote only the well-being of the body aesthetically, but as a set of activities responsible for improvement of health, intelligence, emotional, creativity, as well as an instrument of social integration. The practice of physical activity releases endorphins in the brain, which is a natural substance produced by the brain that is associated with well-being, mood and joy, and this effect occurs during and after physical activity.
I) Locus- the chromosomal site where a specific gene is located. A locus is a fixed position on a chromosome, like the position of a gene or a marker. Each chromosome carries ,many genes; human's estimated haploid (n) protein coding genes are about 20,000, on the 23 different chromosomes.
ii) Interference; the observed double crossover frequency differs from the expected double crossover frequency. Cross over interference is used to refer to the non-random placement of crossovers with respect to each other during meiosis. It results in widely spaced crossovers along chromosomes. Interference may exert its effect across whole chromosomes. As chromosomes in many eukaryotes are large, interference must be able to act over megabase lengths of DNA.
iii) Linkage- the tendency for genes located in close proximity on the same chromosome to be inherited together. Normally when two genes are close together on the same chromosome, they do not assort independently and are said to be linked. Whereas genes located on different chromosomes assort independently and have a recombination frequency of 50%, linked genes have a recombination frequency that is less than 50%.
iv) Recombination- the process by which a new pattern of alleles on a chromosome is generated. Genetic recombination is the production of offspring with combinations f traits that differ from those found in either parent. During meiosis in eukaryotes, genetic recombination involves the pairing of homologous chromosomes. This may be followed by information transfer between the chromosomes.
Answer:Thirty years ago, 45 out of 200 individuals, or 22.5% of individuals, were at least 1.2 meters tall. Presently, 50.5% of individuals are at least 1.2 meters tall. Meanwhile, individuals below 1.2 meters in height have decreased significantly between the two years of data. This data supports the argument that directional selection is occurring.
Explanation:
Answer:
They concluded that these antibodies were a) Globular proteins
Explanation:
Globular proteins are known to be water-soluble, spherical in shape and to be polypeptides as well. Compared to the other options provided, the selected one is the most correct.
Answer:
a) Photosystem I requires the use of light converting an excited NADP + electron, reducing it to NADPH. In photosystems I and II, the passage of electrons to a series of redox reactions will be shown due to the absorption of light energy by the chlorophyll molecules.
(b) The control must be RuBisco, because for most photosynthesis responses to light, temperature and carbon dioxide, it produces oxygenation and carboxylation reactions, thus reflecting kinetic properties.
(c) plants can increase the ability in a variable ecosystem thanks to the flexibility of photosynthetic pigments, through these the necessary solar energy for photosynthesis is captured, according to each light spectrum there will be a specific pigment.
