Answer:

germline mutation

Explanation:

It is germ line mutation which can be passed on from one generation to another that means from parents to off springs. The term germ relates to the one which is capable of germination i.e. reproduction.

There are two types of cells in our body (1) somatic cells (2) germ cells.

Germ cells are the cells which are produced in the primary sex organs like gonads. Since gonads are responsible for producing gametes (ovum and sperms) which are capable of reproducing an entire organism after fertilization, they are regarded as germ cells. Somatic cells on the other hand are not responsible for fertilization. So, if a mutation occurs in germ cells which is known as germline mutation, it will pass on to the off spring while a mutation in somatic cells will be restricted to the individual without being passed on to the next generation.

Part A: A scientist examines a fruit fly gene involved with the regulation of body development. A section of the DNA sequence fo

Leokris [45]

Answer:

Part A: Thr-Leu-Val

Part B: ACC-UUG-GUU

Explanation:

When you transcribe a DNA sequence to mRNA, you need to remember that in RNA there is no Thymine (T), instead it has Uracil (U). So the base pairings would be like this compared to DNA base pairing:

DNA RNA

A-T A-U

T-A T-A

C-G G-C

G-C C-G

Given the sequence the transcription will be as follows:

DNA : TGG - AAC - CAA

mRNA: ACC - UUG - GUU

Next, to translate it into amino acids, you will use the chart. Now amino acids pair in codons (3 base pairs at a time). Let's take the first codon in your sequence:

ACC

1st 2nd 3rd

A C C

Using the column on the left, find the row that matches it, so in this case A.

At the very top, there is another row of letters, looking at the row of A only, look for the column of the second base which is C.

Lastly, look at the right most column and find the letter that matches the third base within the box where A and C intersect. In this case, C is your third base.

The amino acid where all three intersect is your first amino acid which is Thr.

Just do this for the next codons and you will come up with the answer.

Sloan [31]

Answer:

Rapid increases in water temperature cause extensive fish kills

Explanation:

Biotic factors are all living organisms that contribute to an ecosystem. On the other hand, abiotic factors are non-living factors, such as climatic factors (temperature, rainfall, wind), edaphic factors (soil type, soil texture, soil aeration etc). Changes of abiotic factors can have a huge influence on living organisms of ecosystem. The effects might be benefical or harmful.

Some of the most common abiotic factors that can impact a marine ecosystem are water temperature, currents, light, alkalinity, oxygent concentration etc.
