Which statement is true about the total number of chromosomes in most eukaryotic cells? A. Chromosome numbers vary widely. B. Pl
svet-max [94.6K]

Answer: The correct answer is- A. Chromosome numbers vary widely.

Chromosome can be described as thread like structure that is composed of DNA ( deoxyribonucleic acid) and possesses genes ( segment of DNA coding for a particular protein) on it.

Eukaryotic cells ( such as plant cell, animal cell) have variable number of chromosomes.

For instance, human beings have 23 pairs of chromosomes whereas it is different in plants depending on the species.

Thus, A) is the right answer.

The slower an object moves the more kinetic energy it has.<br><br> True<br><br> False
Lady_Fox [76]
False , because its backwards 

There will be more energy 'locked away' in a massive lorry that is moving at 20 m/s than in a motorbike travelling at the same speed.



Also the faster it goes the more kinetic energy the lorry will have.

A lorry moving at high speed will have much more kinetic energy than a lorry moving at low speed.

Therefore a fast moving car or lorry will cause more damage in an accident than a slow moving one because this kinetic energy has to be turned into other forms including sound, heat and stress on the other vehicles.

The kinetic energy of an object therefore depends on two things:
(a) the mass of the object (m)
(b) its speed (v)

The formula for kinetic energy of an object of mass m travelling at speed v is:


<span>Kinetic energy (k.e) = 練v<span>2</span></span>

Hybridomas, which produce monoclonal antibodies, are made by fusing cells of the immune system with.
yuradex [85]

Monoclonal antibodies are made by the fusion of cells of the immune system with B lymphocytes and myeloma cells.

<h3>What is Hybridoma technology?</h3>
  • It is one of the best technologies that is used to produce the monoclonal antibody.
  • In this hybridoma technology the B lymphocytes that are antibody producing are isolated from a source after the immunization with a specific antigen and then are fused with myeloma cell line to form hybrid cells that are also called as hybridoma cell lines.
  • The hybridoma cell lines are then cultured in the laboratory with specific antigen and then the monoclonal antibodies are produced.
  • This can be done in in-vivo or in-vitro condition.
  • This method is preferred over all because the production of antibodies by this method is good as the antibodies produced are of high purity and highly sensitive and specific.
  • These cell lines can also be preserved for a long time.
  • Hybridoma technology has resulted in production of different varieties of monoclonal antibodies with specificity with specific antigens as the monoclonal antibodies are produced by single parental B cells.

Cold water holds more dissolved gas than warm water.
grin007 [14]

Answer:

The temperature and salinity of water influence how much oxygen it can hold. Warm water holds less dissolved oxygen than cold water because the molecules are moving faster than in cold water and thereby allow oxygen to escape from the water.
