Which lung sound possesses the characteristics of being louder and higher in pitch, with a short silence between inspiration and
andreyandreev [35.5K]

Answer:

C. Bronchial

Explanation:

The different types of lung sounds, also known as breath sounds differ from each other with respect to their location, pitch, relative duration, and intensity.

The bronchial breath sounds are heard just above the clavicle on either side of sternum bone and are characterized by loud amplitude, harsh quality, and high pitch. The bronchial breath sounds are hollow tubular.

The bronchial breath sounds have a short period of silence between the inspiratory and expiratory sounds. The expiratory bronchial sounds last longer than the inspiratory bronchial sounds (I<E).

At what phase of meiosis is the number of chromosomes per cell doubled? What happens after that so that the number of chromosome
Vlad1618 [11]

Answer:

During the S phase at interphase in meiosis I

Explanation:

During the S (DNA synthesis) phase at interphase in meiosis I, DNA replication occurs here where the chromosomes are doubled. This phase does not occur in meiosis II. At the end of meiosis II, the chromosome number becomes halved in the sex cells. The cell just goes on to divide to ensure haploidy of chromosomes in the gametes such that the sperm from the male and egg from female are both haploid. Fertilization brings about diploidy of the zygote itself

Mammalian erythrocyte lacks nucleus. Why? Give reason. ​
faust18 [17]

Explanation:

Complete answer:

A mature erythrocyte lacks nucleus and mitochondria so as to make a place for the accommodation of more hemoglobin and hence more oxygen molecules. Lack of such organelles also provides the peculiar biconcave appearance of RBCs that aids in efficient diffusion. Young mammalian RBCs are nucleated.

How does the energy of an electron relate with the distance from the nucleus?
Makovka662 [10]

d. The farther an electron is from the nucleus, the greater its energy.

Explanation:

The energy of an electron relates with the distance from the nucleus in that the farther an electron is from the nucleus, the greater its energy.

The nucleus of an atom is where the protons and neutrons are located.

Electrons orbits round the nucleus in certain permissible energy levels.

  • According to quantum mechanics and the Bohr's model of the atom, the energy levels of orbital electron is quantized.
  • The ground state is the state with the lowest energy and close to the nucleus.
  • The outer most electrons are located in the highest energy levels
  • Therefore, the farther an electrons is from the nucleus, the greater its energy
