Tay Sachs is a recessive disease (t) that causes an inability to process certain nutrients which then build up in the brain, resulting in death (at a very young age). A man and a woman had a child born with this disease, but neither have the disease (otherwise they would have died as young children!). What must their genotype be in order for them to have a child with the disease? Explain your reasoning.

Answers

Answer:

Tt (both heterozygous)

Explanation:

According to this question, Tay Sachs is a recessive disease (t) that causes an inability to process certain nutrients which then build up in the brain, resulting in death (at a very young age). This means that this disease can only be phenotypically expressed when the recessive alleles are both present in the gene i.e. tt.

If a man and a woman had a child born with this disease, but neither have the disease, it means that both of the parents are dominant but heterozygous (carriers) for the disease. This means that they both have a genotype "Tt". So when they both mate i.e. Tt × Tt, they produce the following offsprings: TT, Tt, Tt, and tt.

The "tt" offspring is the child with the Tay Sachs disease.

Which type of mountain is formed due to the collision of two different kinds
of plates

Answers

Fold mountains
When plates collide or undergo subduction (that is – ride one over another), the plates tend to buckle and fold, forming mountains. Most of the major continental mountain ranges are associated with thrusting and folding or orogenesis. Examples are the Balkan Mountains, the Jura and the Zagros mountains.

He and a doctor were trying to determine if electric shock could be used to cure illnesses. One day, when he turned on the switches to treat a patient in another room, he heard the patient yelp. However, the voice had not come from the next roomit had come from the copper wire that ran between them!Following that fateful day, Meucci left his medical experiments behind. Instead, he set a goal to develop that talking wire into a machine he called a talking telegraph. After six years of trials and tests, he was able to build a working model. Meucci found it to be a useful device almost immediately.Based on the sequence of events in the excerpt, which sentence best states a cause-and-effect relationship?Because Antonio Meucci was a trained engineer, he was able to invent a talking telegraph.Because electricity was used to cure sickness, Antonio Meucci invented the talking telegraph.Because the device was so useful, Antonio Meucci invented the talking telegraph.Because he heard a patients yelp through a copper wire, Antonio Meucci invented the talking telegraph.
