Answer:

1.) Are tightly coiled bundles of DNA

2.) Carry many genes

3.) Are found inside the nucleus of eukaryote

4.) Can be used to diagnose genetic disorders

Explanation:

A chromosome is a thread-like structure made up of DNA. The chromosomes are made of DNA which are tightly coiled around protein.

Chromosomes carry hundreds and thousands of genes. The number of genes in a cell outnumbers the number of chromosomes.

In eukaryotic cells, all the chromosomes are found inside the nucleus of eukaryote.

The chromosomes and DNA can be examined so as to diagnose genetic disorders.

Write a balanced nuclear equation for the following: The nuclide astatine-218 undergoes alpha emission to give bismuth-214

galina1969 [7]

Answer:

$^{218}_{85}At\rightarrow ^{214}_{83}Bi+^{4}_{2}He$

Explanation:

Hello there!

In this case, since the radioactive reaction for the alpha emission of astatine-218 to bismith-214 involve the release of a helium atom as shown below:

$^{218}_{85}At\rightarrow ^{214}_{83}Bi+^{4}_{2}He$

Whereas the atomic number decreases by 2 and the mass number by 4 in agreement to the release of the Helium atom.

Describe how magnetic forces and electric forces are similar and different from each other

PtichkaEL [24]

<em>ANSWER:</em>

Objects that have the same charge, both positive or both negative, repel each other, and those with opposite charges attract each other. ... Similar to electric charges, opposite poles attract, and like poles repel. The stronger the magnets and the closer together they are, the stronger the magnetic force between them.

What do you mean by Latent heat of evaporation! (not vaporisation/fusion) Kindly tell from Science NCERT class 9.

Ne4ueva [31]

Since none answered from Indian NCERT yet, let me give a simple definition from ICSE..
Latent Heat of vapourisation is the heat energy required to convert unit mass of a substance from liquid to vapour state WITHOUT ANY CHANGE IN ITS TEMPERATURE....
hope this helps!
