Answer:
4l = 24
so l=6
now
l*l =6*6
= 36 square cm
Answer:
36cm²
Explanation:
Perimeter of a square = 4x (sum of all 4 sides)
Perimeter = 24 cm (given)
[tex]\implies [/tex]4x = 24
x = 24/4 = 6 cm
Now, area of a square = (side)²
Area = (6)²
= 36 cm²

1. All of the following are correct statements about enzyme regulation EXCEPT: a. Enzymes can be inhibited by the products they produce. b. Enzymes can be inactivated by the addition of a functional group. c. Coenzyme and substrate availability can regulate enzyme reaction rate. d. The reaction rate slows as equilibrium is approached. e. The activity of an enzyme is covalently affected by allosteric regulators. ANSWER: e 2. All of the following are examples of a zymogen and its activating protease EXCEPT: a. chymotrypsinogen and chymotrypsin. b. procarboxypeptidase and elastase. c. proelastase and elastase. d. pepsinogen and pepsin. e. trypsinogen and trypsin. ANSWER: b 3. Proinsulin is converted into insulin by: a. proteolytic excision of a specific peptide. b. allosteric binding of glucose. c. phosphorylation to the active form. d. removal of phosphate by converter enzymes. e. none of the above. ANSWER: a
Answer:
1-For the first one, the statement which is not correct about enzyme regulation is the statement e which is The activity of an enzyme is covalently affected by allosteric regulators
2-The example which does not have a zymogen and activating protease is example b which is procarboxypeptidase and elastase.
3-The process by which proinsulin is converted into insulin is by method a which is proteolytic excision of a specific peptide.
Explanation:
1-All the other statements are correct as indicated below:
a-Enzymes can be inhibited by the products they produce. This is true because the rate of production is reduced in cases of some products. this indicates that the enzymes are not being able to further act.
b-Enzymes can be inactivated by the addition of a functional group. This is true because enzymes can be activated and inactivated manually.
c-Coenzyme and substrate availability can regulate enzyme reaction rate. This is true because lack or shortage conenzyme or substrate can reduce the reaction rate due to lack of availability of required components.
d-The reaction rate slows as equilibrium is approached. This is true as the reaction reaches equilbrium less products are converted back to reactants and less reactants are converted into products.
2-
Similarly all the other examples for 2 have either an activating protease or zymogen except procarboxypeptidase and elastase.
3-
The proinsulin has a specific peptide which is excised thus only option a is correct.
Which traits do you think are very strictly determined by your genetic make-up (genotype)?
Answer:
Reproduction, growth and development, regulation, homeostasis, and energy processing.
Explanation:
Reproduction, growth and development, regulation, homeostasis, and energy processing are the traits or characteristics that are determined by the genotype. These traits are under the control of genes of an organisms and can be changed if the change in the genes occurs while on the other hand, the physical characteristics of an organisms are determined by phenotype means phenotype is responsible for the appearance of an organisms.

The probability that this couple will have a child with Duchenne Muscular Dystrophy is 50/50
Explanation:
This Punnett square shows our woman as "xx" and our man at "xy". Knowing this, we can now look back at the Punnett square's results. Out of the four squares, two of them are fill with the woman's carried condition, but the other two are also filled with the man's. So, that leaves us with a 50 percent chance that their child will have DMD.

Your friend Joe has a younger brother Sam and two older sisters. Sam has a strange disorder that has caused his hair to turn green. The doctor says that this is caused by a single gene that is inherited, and that boys are more likely to have green hair then girls. However Joe, his sisters, and both of his parents have normal hair color. Joe does not know much biology and is confused. Explain to Joe how his brother's condition could have arisen even though Joe has normal hair. Then discuss the likelihood that a) Joe, and b) Sam will have children with green hair. Assume that they both marry women with normal hair color. You will need to include information on meiosis and transmission of genes to assure that Joe understands. HINT: As part of your answer, indicate the percent of girls vs. boys that you predict would have green hair if fathered by Joe vs. Sam.
Answer:
The correct answer is - it is due to the case of sex-linked recessive disorder.
Explanation:
It is pointed out by the doctor that Sam has a condition due to recessive allele and it is given that boys have this condition more than girls which suggests that it is a sex-linked recessive disorder. This comes from their parents but it is given that the father has normal hair which means the father has no recessive allele, then it must come from the mother even mother has not this condition but she could be a carrier for this trait.
Joe and his sister do not have this condition as they get the normal dominant allele from mother and father.
The chances of being a carrier by his sisters are 50%. If Joe marries
IF Joe marries a non-carrier woman, he will have all normal children with no green hair. IF Joe marries a normal hair color carrier women then there would 25% chances of being diseased offspring and 50% chances of being a carrier, and if women is completely normal then all offspring will be normal.
carrier woman, his children will have a 25% chance of being green-haired. A 25% chance of being
IF Sam marries a normal woman, the children will have a 25% chance of being a carrier, a 25% chance of being green-haired, and a 50% chance of being normal.

A watershed, also known as a drainage basin, is an area of land where water drains to a central point like a lake river or an ocean. natural vegetation in the landscape, helps maintain the natural flow of Regine of water and rapid change in water level in lakes and wetlands. imagine a position of a wetland that has changed as scenes in the image. predict what will happen to the natural flow of water is natural vegetation as replaced by impervious surfaces
A) groundwater flows increase to its endpoint causing flooding
B) runoff will increase and less water will penetrate the soil to become groundwater
C) groundwater will puddle up and remain in one place instead of flowing to a central point
D) impervious surfaces such as roads and parking lots will divert water flow and it will not reach its endpoint
Answer:
B) runoff will increase and less water will penetrate the soil to become groundwater.
D) impervious surfaces such as roads and parking lots will divert water flow and it will not reach its endpoint
Explanation:
The runoff will increase and less water will penetrate into the soil to become groundwater if natural vegetation is replaced by impervious surfaces. The natural vegetation helps to lower the speed and intensity by absorbing large amount of water. Due to this absorbing, there is an increase occur in the concentration of groundwater level which increases underground water reserves for the coming generations. These impervious surfaces also act as a barrier that diverts water and prevents the water to reach to its ending point.

The four main forces that drive evolution are mutation, natural selection, genetic drift, and gene flow. All of these forces can cause a change in what?
Answer:
Allele frequencies
Explanation:
The only component that is transmitted from generation to generation is the genetic material (genes), the fact that an individual leaves more descendants implies that their genetic variants (alleles) will be more represented in the next generation. The frequencies of the different alleles will change from one generation to another, and this change will be irreversible when the set of genes in the population is considered, since it is highly unlikely that a previous configuration will be returned in all gene variants. Hence, from a population point of view, evolution is ultimately a cumulative and irreversible change in the proportions of different gene variants in populations. The agents that change the allele (or gene) frequencies of populations, that is, factors of evolution, are mutation, genetic drift, migration, and natural selection. Mutation is a factor that increases genetic diversity. Natural selection is the process by which the gene frequencies involved with certain traits vary from generation to generation, since some variants of the trait have a greater capacity than others to survive and produce offspring. The mutation rate of a gene or DNA sequence is the frequency at which new mutations occur in that gene or sequence in each generation. In each generation there is a gene raffle during the transmission of gametes from parents to children which is known as genetic drift. In the absence of gene flow, gene drift will also lead to local differences in allele frequencies.

Which process best explains how antibiotic resistance in bacteria can occur?
Answer:
Antibiotic resistance is a consequence of evolution via natural selection. The antibiotic action is an environmental pressure; those bacteria which have a mutation allowing them to survive will live on to reproduce. They will then pass this trait to their offspring, which will be a fully resistant generation.
