Hemophilia is an X-linked recessive disorder (Xh) that is passed through generations and can be traced by using a pedigree. What is the probability that a female child of Charles and Marie would suffer from hemophilia?a. 0 percent
b. 25 percent
c. 50 percent
d. 100 percent

Answers

Answer 1

Answer: Since hemophilia is an X-linked recessive disorder, the probability depends on the X alleles.
So, if father has dominant allele (H), the probability that a female child would suffer from hemophilia (genotype: hh) is 0%, no matter of mother's genotype:

Father Mother
Parents: H x Hh
Daughter: HH or Hh

Father Mother
Parents: H x HH
Daughter: HH

Father Mother
Parents: H x hh
Daughter: Hh or Hh

But, if the father has recessive allele, the probability that a female child would suffer from hemophilia (genotype: hh) will depend on mother's genotype.
If mother is dominant homozygous, there will be 0% of possibility:
Father Mother
Parents: h x HH
Daughter: Hh

If mother is recessive homozygous, the possibility is 100%:
Father Mother
Parents: h x hh
Daughter: hh

If mother is heterozygous, the possibility is 50%:
Father Mother
Parents: h x Hh
Daughter: Hh or hh

Why do you think species remain in a stage of stasis? A. A stable ecological niche leads to absence of selection pressure, which in turn causes species to remain unmodified or in stasis.
B. An unstable ecological niche leads to various selection pressures, which in turn causes the species to remain in a stage of stasis.
C. A stable ecological niche leads to various selection pressures, which in turn causes species to remain unmodified or in stasis.

Answers

I believe that species remain in a stage of stasis because they have completely adapted to the environment they are in and are able to live successfully without any evolutionary changes. The species has all the necessary traits in order to survive.

Answer: A) A stable ecological niche leads to absence of selection pressure, which in turn causes species to remain unmodified or in stasis.

A recent study has shown an increase in the number of predators in an ecosystem. Which of the following is a possible cause for the growth?a. A decrease in the population of prey it feeds on.
b. An increase in the population of prey it feeds on
c. A decrease in the biodiversity of the ecosystem
d. An increase in the number of predators that feed on it

Answers

Answer: b. An increase in the population of prey it feeds on.

Explanation:

A predator is a kind of organism which kills the other organisms so as to obtain them as food. The organism which is killed is called as prey. If the population of predators in an ecosystem increases the result for this increase is the increase in population of prey which the predator population can use as food to survive, reproduce and grow in number.

Answer: b. An increase in the population of prey it feeds on.

What determines the differences between the way men and women speak?

Answers

Testosterone! Hormones jn general make a large difference

Final answer:

Differences between the way men and women speak are largely culturally determined, though early research suggested they were due to societal socialization. Modern research indicates the impact of linguistic determinism - the way one's languages can influence one's thoughts and perceptions. Importantly, these gendered speech patterns are not a universal biological fact, but vary across different cultures.

Explanation:

Various factors, predominantly cultural and social, contribute to the differences between men's and women's speech. Early research theories such as those from Robin Lakoff suggested that societal socialization resulted in women's speech being seen as uncertain, excessively polite, and full of hedges. Likewise, Deborah Tannen argued that men and women communicate differently, with men focusing more on status and women on building connections through conversation.

However, more recent studies argue against this concrete division. Janet Hyde, challenging traditional gender role-based speech patterns, conducted a comprehensive analysis which showed minimal differences in verbal skills between boys and girls. Similarly, language research on cultural aspects from Madagascar and New Guinea reveal that speech patterns associated with gender are indeed culturally relative.

Another relevant factor is the role of linguistic determinism, which suggests that the language one speaks can significantly influence one’s thoughts and perceptions. This idea was demonstrated in Lera Boroditsky's research, that native German and Spanish speakers, in which nouns are gendered, describe things differently depending on the noun's gender in their language, even when communicating in a gender-neutral language such as English.

In conclusion, while there may be some observable differences in the way men and women speak, gendered speech patterns are largely cultural and vary significantly across different societies, and they cannot be generalized or naturalized as biological phenomena.
