Mono hybrid cross dihybrid cross homozygous cross heterozygous
Answer:
Natural selection disrupts the genetic equilibrium by favoring the genes for the traits that impart survival advantage to individuals.
Explanation:
Natural selection refers to the unequal survival rate of individuals of a population due to the presence of some beneficial adaptive genetic trait. These individuals are able to survive more and leave more progeny. Over generations, the population has increased number of these individuals leading to evolution of a population with different allele frequencies.
For example, the frequency of gene for antibiotic resistance in the bacterial population was increased once humans started using antibiotics to control the bacterial population. This led to the evolution of the bacterial population with antibiotic resistance.
False. Agribusiness is agriculture conducted on a large, commercial scale.
I can’t answer how lichens arrive in a barren landscape but I can answer the 2nd part
Lichens grow when exposed to water. When wet, lichens begin to photosynthesize.
Answer:
Centre of Gravity
The centre of gravity (COG) of the human body is a hypothetical point around which the force of gravity appears to act. It is point at which the combined mass of the body appears to be concentrated[1]. Because it is a hypothetical point, the COG need not lie within the physical bounds of an object or person. One subjective way (there are objective measures) to approximate the COG of an object is to visualise it balancing on one finger.
Centre of Gravity in the Human Body
In the anatomical position, the COG lies approximately anterior to the second sacral vertebra. However, since human beings do not remain fixed in the anatomical position, the precise location of the COG changes constantly with every new position of the body and limbs. The bodily proportions of the individual will also affect the location of the COG.
