The cascade of different hormones,that occur during adolescence is referred to as puberty.
Explanation:
Puberty is defined as a period of sexual maturity when Reproductive organ of the individual become functional. This results from several hormonal changes that take place in the body during this period.
In males, puberty is characterized by onset of spermatogenesis and in females, it is characterized by onset of ovulation or menstrual cycle.
During puberty, the individual develops secondary sex characters.

Questions 5-8: The most likely mode of inheritance for each pedigree cannot be determined without reviewing the attached powerpoint presentation.
Explanation:
The most likely mode of inheritance for each pedigree is:
Autosomal dominantAutosomal recessiveAutosomal recessiveX-linked recessiveAutosomal dominantAutosomal recessiveAutosomal dominantAutosomal recessiveThe genetic disorder that exhibits reduced penetrance is Familial hypercholesterolemia. Reduced penetrance refers to the situation where individuals with the disease-causing mutation do not show any symptoms or have a milder form of the disorder. In Familial hypercholesterolemia, individuals with the mutation may have varying levels of high cholesterol, but not all of them will develop severe cardiovascular problems.
The true statement about X-linked dominantgenetic disorders is that affected fathers have 100 percent affected daughters. This means that if a father has an X-linked dominant disorder, all of his daughters will inherit the disorder.
In the case of a hemophilia carrier being married to a person with hemophilia, the expected outcome for their offspring is that all sons are affected and 50 percent of daughters are unaffected. Hemophilia is an X-linked recessive disorder, which means that it is more commonly seen in males. Sons inherit the affected X chromosome from their mother, while daughters have a 50% chance of inheriting the affected X chromosome.
In the case of autosomal recessive disorders, the true statement is that if both parents are affected, all children will be affected. Autosomal recessive disorders require both copies of a gene to be mutated in order for the disorder to be present. If both parents are carriers of the mutated gene, there is a 25% chance that each child will inherit two copies of the mutated gene and therefore be affected by the disorder.
For each pedigree, the most likely mode of inheritance can be determined by analyzing the pattern of affected individuals in the family. The options are:

Male chimpanzee sleeping in tree for an hour
b.
Baby chimpanzee playing in tree branches for an hour
c.
Female chimpanzee walks away when male chimpanzee approaches
d.
Male chimpanzee eats bananas rather than vegetables during feeding time
Correct answer: C). Female chimpanzee walks away when male chimpanzee approaches
The male chimpanzee spends most of their time in a community in which they are born. In contrast to male-female chimpanzee live their group after their birth to join the neighboring group when they are mature.
Female chimpanzee is known to spend their most of the time their child or with the other female rather than the male. Female chimpanzee is known to form, a coalition against a bullying male.
Hence, the correct answer would be option C.
Boiling
Freezing
Evaporating
The answer to the question above is letter a. melting.
>Exothermic is the giving off heat energy the transfer of energy to the surroundings.
>In exothermic reaction, the energy is usually transferred as heat energy
> Other example of exothermic is combustion
Answer:
An exoskeleton.
Explanation:
Tough outer shell of many insects is known as exoskeleton that represents an external skeleton. The exoskeleton provides protection and support to the insects body as they lack an internal skeletal system as higher organisms. In insects, it is made up of chitin.
Exoskeleton also plays role in sensing, feeding, excretion, and protection against desiccation in land insects.
Thus, the correct word to be filled in the blank is 'exoskeleton.'
Answer: Endothermic
Explanation:
An endothermic reaction occurs when energy is absorbed as heat, while a reaction is exothermic when heat is released. Thereby, these type of reactions require external energy to proceed and heat is the reactant.
So, an endothermic reaction absorbs heat from the surrounding environment and stores that energy in the bonds of a new molecule formed, and this results in a decrease in temperature.
Enthalpy usually increases in endothermic reactions. However, a spontaneous endothermic reaction can occur if changes in entropy and enthalpy yield a negative Gibbs free energy.
