Explanation:
The genes that determine color and pattern are linked.
- Solid pattern allele (L) is dominant over lined pattern (l)
- Blue color allele (B) is dominant over aqua color (b)
<h3><u>Initial cross</u></h3>
Homozygous lined aqua beetle has the genotype <em>lb/lb</em>
It can produce only 1 type of gamete: <em>lb</em>
X
Homozygous solid blue beetle has the genotype<em> </em><em>LB/LB</em>
It can produce only 1 type of gamete:<em> </em><em>LB</em>
The F1 is formed by the union of the parents' gametes, so it will have the genotype <em>lb/LB</em>
<h3><u>F1 test cross</u></h3>
Test crosses involve a homozygous recessive individual.
<u>The homozygous recessive individual</u><u><em> lb/lb</em></u><u> can only produce 1 type of gamete:</u>
<u>The F1 individual </u><em><u>lb/LB</u></em><u> can produce 4 types of gametes:</u>
- lb - parental
- LB - parental
- lB - recombinant
- Lb - recombinant
Answer:
Action potential.
Explanation:
Action potential may be defined as the change of the membrane potential of the cell with response to the stimulus. The different ions enter and exit the cells.
Action potential generates in the cell when the threshold voltage - gated channel reaches and opens the voltage gate channel. The opening of voltage gated channel changes the membrane potential of the cell.
Thus, the correct answer is option (4).
Answer:
It will take 83 days to recover the extra cost
Explanation:
To determine the length of time it will take to recover the extra cost, it will be logical that we compare the $200 extra cost to the total savings in running cost made for a year and covert this into days
The total savings in running cost is the cost savings per hour multiplied by the number of hours in a year.
The calculations are set below:
Savings in running cost per hour = $0.1
Total savings in a year = 365 days × $0.1 × 24 = $876
Extra cost of Energy Star refrigerator = $200
If total savings for a year is $876 , then equivalent length of time to save $200 would be
Length of time = 200/876 × 365 days = 83 days
It will take 83 days to recover the extra cost
