The correct answer is option D, that is, about 1 percent.

Pertussis also is known as a whooping cough is a highly contagious bacterial disorder. In the beginning, the symptoms are generally identical to those of the common cold with a fever, runny nose, and mild cough. This is succeeded by weeks of extreme coughing fits.

Pertussis is caused by the bacterium <em>Bordetella pertussis</em>, it is an airborne disease. An estimated 16.3 million people globally were infected in 2015. The majority of the cases take place in the developing nations, and the individuals of all age groups can get affected. About 1 percent of the patients with whooping cough die annually.

Full Question (figure attached):

Nucleic acid segments and ar

DNA and RNA are nucleic acids that can store biological information based on the sequence of their nucleotide monomers. Figure 1 shows a short segment of each of the two types of nucleic acids. Which of the following best describes a structural difference between DNA and RNA?

A. DNA contains four types of nitrogenous bases, whereas RNA contains only two types of nitrogenous bases

B. The backbone of DNA contains deoxyibose, whereas the backbon e of RNA contains ribose.

C. A DNA molecule is composed of two parallel strands with the same 5'-3' directionality, whereas an RNA molecule is composed of only one strand

D. Phosphate groups provide rigidity to DNA, but RNA is flexible and contains no phosphate groups

Answer:

B. The backbone of DNA contains deoxyibose, whereas the backbon e of RNA contains ribose.

Explanation:

A. DNA contains four types of nitrogenous bases, whereas RNA contains only two types of nitrogenous bases - this is false. Both contain four types of nitrogenous bases. DNA contains cytosine, guanine, adenosine and thymine, whereas RNA contains cytosine, guanine, adenine, and uracil.

B. The backbone of DNA contains deoxyibose, whereas the backbon e of RNA contains ribose. - this is true, each nucleotide in DNA contains a deoxyribose sugar, whereas each nucleotide in RNA contains a ribose sugar

C. A DNA molecule is composed of two parallel strands with the same 5'-3' directionality, whereas an RNA molecule is composed of only one strand - this is false. DNA is composed of 2 strands, and RNA is composed of one, but the DNA strands run in an anti-parallel configuration (one runs 5'-3', the other runs 3'-5')

D. Phosphate groups provide rigidity to DNA, but RNA is flexible and contains no phosphate groups - this is false, both DNA and RNA nucleotides contain phosphate groups

What is the lateral pointine tegementum?

alexandr402 [8]

Answer:

What is the lateral pointine tegementum?----------->The tegmentum (from Latin for "covering") is a general area within the brainstem. The tegmentum is the ventral part of the midbrain and the tectum is the dorsal part of the midbrain. It is located between the ventricular system and distinctive basal or ventral structures at each level. It forms the floor of the midbrain (mesencephalon) whereas the tectum forms the ceiling. ------------>The pontine tegmentum, or dorsal pons, is located within the brainstem, and is one of two parts of the pons, the other being the ventral pons or basilar part of the pons. The pontine tegmentum can be defined in contrast to the basilar pons: basilar pons contains the corticospinal tract running craniocaudally and can be considered the rostral extension of the ventral medulla oblongata; however, basilar pons is distinguished from ventral medulla oblongata in that it contains additional transverse pontine fibres that continue laterally to become the middle cerebellar peduncle.
