b. promotion of pesticide resistance in insects
c. harmful to wildlife
d. pollution
Answer:
a. toxic to insects is the correct answer.
Explanation:
B) Mutations can be positive and produce organisms with improved traits.
C) Mutations can be fatal to the organism that has a mutation, if the mutation is in a critical gene.
D) Mutations can be silent, and not affect the organism that has them, if the mutation is in a non-critical area.
Answer: The correct answer is- A) Mutations must be present in parents and then passed to offspring.
Mutation can be described as the permanent change in the genetic material ( DNA) of an organism. It can be beneficial or harmful to the life form. Mutations can be heritable ( that is passed from one generation to the next) or non inheritable ( not passed from parents to offsprings).
A silent mutation ( change in the nucleotide sequence without any change in the amino acid sequence) that does not show any observable effects in the phenotype of the organism.
Thus, only option A) is not true about mutation.
All the statements are true about mutations except Mutations must be present in parents and then passed to offspring.
Thus, An organism's observable traits, or phenotype, may or may not change as a result of a mutation. Evolution, cancer, and the maturation of the immune system, including junctional variety, are among the normal and malignant biological processes in which mutations play a role.
All genetic variety originates from mutation, which also provides the basis for the action of evolutionary forces like natural selection.
Sequence changes can take many distinct forms as a result of mutation. Gene mutations can have no effect, change the gene's product, or stop the gene from working fully or correctly. Non-genic areas are likewise susceptible to mutation.
Thus, All the statements are true about mutations except Mutations must be present in parents and then passed to offspring.

b)Enzymes increase the free energy of the reactants to make the reaction go faster.
c)Enzymes provide the activation energy for the reactions they facilitate.
d)Enzymes lower the activation energy so that reactants absorb enough energy to reach transition state.
Answer:
An autosome corresponds to a somatic chromosome, which defines structural and functional characteristics in an individual, while the gamete is a cell containing autosomes, useful in sexual reproduction.
Explanation:
The somatic chromosomes are called autosomes, since they contain the genetic information necessary to define the structure and functions of a living being. In humans, there are 23 pairs of chromosomes, of which 22 pairs correspond to autosomes.
The gametes, or sex cells, are in charge of transmitting the genetic information from parents to offspring, and are formed by chromosomes. As gametes are haploid cells, they possess half of the chromosome load, that is, in the human being there are 22 autosomes.
Generally speaking, an autosome is a somatic chromosome, while a gamete is a cell containing autosomes.
Answer:
Marine debris consists of most anything used and discarded by humans. Winds, rivers and storms can carry this debris to the ocean from far inland, so it is not solely a case of pollution along shorelines.
