Answer:
The Origins Of The Word 'Cell' In the 1660s, Robert Hooke looked through a primitive microscope at a thinly cut piece of cork. He saw a series of walled boxes that reminded him of the tiny rooms, or cellula, occupied by monks. Medical historian Dr. Howard Markel discusses Hooke's coining of the word "cell."
The trait for the type of leaf margin is con-
trolled by 1 pair of alleles. Serrate margin is
dominant over entire margin. Two plants
with serrate margin leaves (1 heterozygous
and 1 homozygous dominant) are crossed.
What is the chance that the offspring have
entire leaves
Since the genotype ss is the only one that produces the entire margin phenotype, the chance of an offspring having entire leaves is 50% (1 out of 2 possible genotypes: ss or Ss/sS).
What is an allele?An allele is a variant form of a gene that can determine a specific trait or characteristic. Genes are located on chromosomes and can have multiple alleles, which can be dominant, recessive, or codominant. Alleles can be inherited from both parents and can interact with other alleles to determine the phenotype of an organism. For example, the gene for eye color in humans has several alleles, including brown, blue, and green.
The offspring will have a 50% chance of having entire leaves.
When the heterozygous (Ss) and homozygous dominant (SS) plants are crossed, their offspring will inherit one allele from each parent. The possible combinations of alleles are: SS, Ss, and sS (which is the same as Ss).
The genotype SS and Ss both have the dominant allele for serrate margins, while the genotype ss has the recessive allele for entire margins.
Therefore, the possible genotypes and their corresponding phenotypes are:
SS: Serrate margin
Ss: Serrate margin
sS: Serrate margin
ss: Entire margin

3. A mass spectrometer is used to get information from
(a) Plants
(c) Rocks
(b) Rubber
(d) Concrete
Answer: Rocks
Explanation:
You earn $17.50/hr and work 40 hr/wk. Your deductions are FICA (7.65%), federal tax withholding (12.3%), and state tax withholding (6.2%). Your housing and fixed expenses are 30% of your realized income per month. You want to save 5 months' worth in an emergency fund within a year. How much do you need to save per month to fund the emergency fund?
Answer:
So, you need to save approximately $258.60 per month to fund your emergency fund within a year based on the given information.
Explanation:
Let's break down the steps to calculate the amount you need to save per month to fund the emergency fund:
Step 1: Calculate your total deductions
Your deductions include FICA (7.65%), federal tax withholding (12.3%), and state tax withholding (6.2%). To calculate the total deductions, we add these percentages:
Total deductions = FICA + federal tax withholding + state tax withholding
Total deductions = 7.65% + 12.3% + 6.2%
Total deductions = 26.15%
Step 2: Calculate your net income per hour
Your net income per hour is the hourly rate minus the total deductions:
Net income per hour = Hourly rate - Total deductions
Net income per hour = $17.50/hr - 26.15%
Net income per hour = $17.50/hr - $4.57/hr
Net income per hour = $12.93/hr
Step 3: Calculate your monthly realized income
Your monthly realized income is the net income per hour multiplied by the number of hours you work per week and the number of weeks in a month:
Monthly realized income = Net income per hour x Number of hours per week x Number of weeks per month
Monthly realized income = $12.93/hr x 40 hr/wk x 4 wk/month
Monthly realized income = $2,068.80/month
Step 4: Calculate your housing and fixed expenses
Your housing and fixed expenses are 30% of your realized income per month:
Housing and fixed expenses = 30% x Monthly realized income
Housing and fixed expenses = 30% x $2,068.80
Housing and fixed expenses = $620.64/month
Step 5: Calculate the total amount needed for the emergency fund
You want to save 5 months' worth of expenses in an emergency fund within a year. So, the total amount needed for the emergency fund is:
Total amount needed for emergency fund = 5 x Housing and fixed expenses
Total amount needed for emergency fund = 5 x $620.64
Total amount needed for emergency fund = $3,103.20
Step 6: Calculate the amount to save per month
To calculate the amount you need to save per month to fund the emergency fund, divide the total amount needed by the number of months in a year:
Amount to save per month = Total amount needed for emergency fund / Number of months in a year
Amount to save per month = $3,103.20 / 12
Amount to save per month ≈ $258.60
So, you need to save approximately $258.60 per month to fund your emergency fund within a year based on the given information.
