The scientist who first organized the periodic elements according to its atomic weight was Alexander Emile Beguyer de Chancourtois. He was followed by John Newlands but they both had trouble arranging the properties because of some similarities that came out of the study.

It was Mendeleev who arranged the elements according to the atomic number that made the periodic table properly arranged he also knows that there are more elements that haven't been discovered.

Now, suppose that the three tomato genes from Part A did not assort independently, but instead were linked to one another on the
Ksenya-84 [330]

Answer:

All eight phenotypes are possible but parental phenotypes will be more in number

Explanation:

In the cross MmDdPp X mmddpp eight types of offspring are possible because MmDdPp will produce eight types of gametes. These offspring are:

  • MDP/mdp
  • Mdp/mdp
  • mDp/mdp
  • mdP/mdp
  • MDp/mdp
  • mDP/mdp
  • MdP/mdp
  • mdp/mdd

In absence of linkage, the genes would have assorted independently producing all the eight types of offspring in equal number. Hence the phenotype ratio would be 1:1:1:1:1:1:1:1.

If the genes are linked they will show the tendency to get inherited together and crossing over will not take place up to the expected degree. Hence fewer recombinants will be produced and more parental type offspring will be produced.

ELEN [110]

Answer:

Speciation is the method by which unique species evolve from a common ancestor. In this case, two of these species that split from a common ancestor interbred and created a hybrid. This hybrid was apparently stronger and possibly better adapted to the environment, which led to extinction of a species formed by the initial speciation event.

omeli [17]

Answer:

B) hypertension and bradycardia.

Explanation:

Autonomic dysreflexia is a syndrome which is characterised by the sudden rise in the blood pressure of the human. The disease is common in the people with a higher level of spinal cord injuries above the T6 level.

The condition occurs when some external stimuli like pain or irritant activate the involuntary response in the body which cause the blood pressure to rise (hypertension). This leads to the slowdown of the heartbeat (bradycardia) to restore the blood pressure but the body cannot restore the blood pressure due to the damage in the spinal cord.

Thus, Option-B is the correct answer.
