Answer:

A:Electrons in Bohr's model are placed in orbits of different energy levels.

Explanation:

Postulates of Bohr's model

1.Electrons revolve around the nucleus in definite circular orbits and these orbits designated by the letter K,L,M..

2.As long as the electrons revolve in particular orbit then they can neither gain nor loose energy.Such orbits are called stationary orbits.

3.When an electron jump from lower to higher orbit then it absorb energy and when an electron jump from high to lower then it release energy in the form of radiations.

4.The angular momentum of an electron is integral multiple of $\frac{h}{2\pi}$ .

But Rutherford model postulates

1.An atom consist of nucleus containing the entire positive charge.The entire mass of an atom concentrated in the nucleus.

2.Size of nucleus is very small as compared to whole atom size.

3.An atom as a whole is electrically neutral with electrons revolves around the nucleus in various orbits.

Hence, Electrons in Bohr's model are placed in orbits of different energy levels is different postulates of Bohr's model from Rutherford model.

Because Rutherford does not tell about energy levels in which electron revolves. He only said that electrons revolves in various orbits.

Answer: A:Electrons in Bohr's model are placed in orbits of different energy levels.

In order to see an absorbance peak in an ir spectrum, the molecule must ___________.

Arte-miy333 [17]

<span>The answer is b. have a change in dipole moment

When a molecule absorbs an infrared ray, its energy will increase. The energy will increase the rotational movement or the molecule. If the energy increases further, it will become the vibrational movement. Dipole moment will be increased if the vibrational movement is increased.</span>

Rabbit ear size tends to decrease as latitude increases. this is an example of _____. (concept 23.1)

crimeas [40]

Rabbit ear size tends to decrease as latitude increases. this is an example of a cline .

A cline can be described as a change of the biological trait of a species across its geographical range. A cline can be genetic for example, change in the allele frequency, or phenotypic (change in body size). The change can be shown as continuous gradation, or it can be more abrupt from one geographic region to the next.

:) please help!!! Briefly describe the traits seen in each genotype:

kolezko [41]

<h2>Answer 1 with Explanation</h2>

Homozygous dominant- It can be an organism if it carries two copies of the same dominant allele as homozygous which clearly means that the organism has a pair of models that is the corresponding allele for a gene. This gene originally belongs to a particular gene that has same alleles on both homologous chromosomes. It is assigned to by capital (XX) in the subjective terminology.

<h2>Answer 2 with Explanation</h2>

Heterozygous dominant is an organism that carries two different alleles of a gene. Though this is originally is referred to as (Tt). Heterozygous means that an organism has two different varieties of the gene within the system of dominant, the protein each makes is slightly different from one another and the organism has both tall and short versions within the dominant.

<h2>Answer 3 with Explanation</h2>

Homozygous recessive is described as an organism that carries two copies of the same recessive allele in the living organisms while they are in process of growth. A recessive gene is one that has to be homozygous to have an effect on the plant's or animal's traits that is naturally in process. This process of homozygous is is referred to by the lower case (xx).
