Answer:
The odd is zero.
Explanation:
Assuming the Huntington disease allele is represent by b. Nomal allele will be B which is the alternate form.
The genotype of the 25 years old woman will be Bb, since she heterozygote.
The genotype of the husband will be BB, since he's free from the trait.
Crossing both genotypes:
Bb x BB = BB, BB, Bb and Bb.
The genotypes of the offspring will be either BB or Bb. They either free from the trait or heterozygote.
<em>Hence, the odds that the couple will have a child with the disorder is 0. They can only produce heterozygotes or totally normal children.</em>
A food web does not represent all the links in an actual ecosystem.
Explanation:
A food web is also called food cycle. It is understood by the natural interconnection of chain and their graphical representation. The concept is given by Charles Elton. He mentioned about the concept of food cycles in Animal Ecology but later this food cycle is replaced by food web.
Food web are limited representation of eco system. Ecologists can keep together all life forms broadly into one of the two categories which is called tropic levels. These two categories are autotrophs and heterotrophs
Answer:
a. True
Explanation:
According to my research on studies conducted by sociologists, I can say that based on the information provided within the question this statement is completely true. This is because many centuries of tradition and cultural perception has made people believe that it is the male's role in a marriage/relationship to provide economically for a family while a woman's role is to take care of the children and house work. This Perception has changed a little bit as time progresses but even in the 21st century many societies still believe the woman in a marriage/relationship should be taking care of the children more than the man/husband.

Answer:
Active transport occur in the uphill direction where passive transport occur in the downhill direction this is the principle comparison between passive transport and active transport.
Explanation:
Passive transport involves simple transport mechanism such as diffusion,osmosis and facilitated diffusion that help in the transport of molecule across the membrane from high concentration region to the region of low concentration untill equilibrium is reached. No additional energy is required to carry out passive transport. oxygen, carbon dioxide,water, glucose molecule are transported by passive transport mechanism.
Active Transport involves various ion channels which helps in the movement of molecules from low concentration region to the high concentration region .Additional energy in form of ATP is required to stimulate the active transport. Various ions such as Na+,K+, Ca2+, amino acids are transported by active transport.
