Answer: Crucial to all life forms

Explanation:

Water is the most important component for the life forms existing on earth. The earth is covered 70 per cent with water.

All the living components would die without water as it is unevitable part of life. It is used for drinking purpose , washing purpose, industries and factories and has many more domestic and commercial purposes.

Water is also known as universal solvent and dissolves many compounds in it.

In garden peas a pure line that is tall with purple flowers is crossed to another pure line that is short with white flowers. Th
defon

Answer:

See the explanation

Explanation:

Answer 1.

As given that in F1 all are short and white then it can be said according to Mendel's law that short and white are dominant over tall and purple.  

Let S for short s for tall and W for white and w for purple allele.

So the genotype of short purple will be Ssww or SSww. So In first case Ssww self crossed then resultant offsprings will be,

................ Sw .................... sw

Sw ........ SSww ............. Ssww

sw ........ Ssww .............. ssww (tall and purple)

So from this 1/4 will be tall and purple while 3/4 will be short and purple.

In second case SSww only short purple progeny will appear.

Answer 2.

2. a) The female progeny will not show any trait because there are two X chromosome in females , so female offspring can be carrier but not show any trait in case of X- linked trait.

2. b) Half of male offsprings show trait because X is inherited from mother. So the chance of having X-linked recessive allele is 1/2.

2. c) The chance of having X linked affect allele in daughter is 1/2. So the chance of inheriting that X to son will be 1/2 so in total there is chance of 1/4 that son will be affected.

2. d) the chance of first child show this trait will be 1/4 in case of male offspring while 0 in case of female offspring.

Hope this helps!

Explain how animal cells make energy for cellular processes.
riadik2000 [5.3K]
Mitochondria are the energy factories of the cells. The energy currency for the work that animals must do is the energy-rich molecule adenosine triphosphate (ATP). The ATP is produced in the mitochondria using energy stored in food. ... This is a very efficient process for using food energy to make ATP.

Translation ends when
Y_Kistochka [10]

<span>Translation

</span>Remember that transcription happens in the nucleus as it changes from DNA to mRNA.  In translation,
    the mRNA first has to leave the nucleus and go into the cytoplasm of the cell.  The process of translation actually occurs in the cell’s ribosomes.

<span>
</span>The process of translation uses the genetic code on the mRNA strand to direct the construction (making) of a protein molecule. <span>
</span>1.  A ribosome attaches to an mRNA molecule in the cytoplasm.<span>
</span>2.  As each codon passes through the ribosome, tRNA molecules bring the matching amino acids into the ribosome.  Each tRNA has a set of 3 unpaired nitrogenous bases called an anticodon which matches up with the codon coming through the ribosome.  So one end of a tRNA has an anticodon and the other end carries the amino acid which is how the code is translated.<span>
</span>3.  The ribosome and the rRNA molecules it contains attach the amino acids together as they are being translated.  The protein chain will keep growing until the ribosome reaches the stop codon on the mRNA.  At that point, translation is done and the ribosome lets go.


Hope this helps!!!
