The correct answer for this question is A. Law of segregation.
All individuals have two alleles for a given trait. According to Mendel's Law of segregation, these alleles are passed down one each from both mother and father.
Explanations;
According to this law of segregation the allele pairs separate or segregate during the formation of gamete, during the process of meiosis, leaving each cell with a single allele for each trait, and randomly unite during fertilization. One pair of allele comes from the mother while the other pair comes from the father, and joins together to form a diploid cell. Therefore, organisms inherit two alleles for each trait one from each parent.
Rarefaction in terms of ecology can be defined as a technique used to assess species richness from the results of sampling.
It allows the calculation of richness of a particular species for a given number of individual samples, and these are based on the construction of rarefaction curves.
Hence, the correct answer is: option A-Creating a representative sample
Answer:
c) receptor; control center; effector.
Explanation:
Homeostasis maintains the internal body conditions almost constant. It includes specific cells that sense any deviations of internal or external conditions from the normal range. These cells are called receptors. The sensory information from the receptors is delivered to the control center. The central nervous system mainly serves as a control system wherein sensory information from the receptors is processed. The control center commands muscles and/or glands to perform desired responses to restore the homeostasis. Here, muscles and glands serve as effectors.
For example, thermoreceptors sense the rise of body temperature and the brain (control center) commands sweat glands (effectors) to produce sweat.
Answer: Higher temperatures disrupt the shape of the active site, which will reduce its activity, or prevent it from working. The enzyme will have been denatured . ... The enzyme, including its active site, will change shape and the substrate no longer fit. The rate of reaction will be affected, or the reaction will stop. So the answer is c i hope this helped:)
