Why might there be more dissolved oxygen in a lake in Vermont than in a similar sized lake in Florida in summer? (20 points)
A.) The sandy bottoms of Florida lakes absorb dissolved oxygen better than the rocks in Vermont.
B.) The cooler water in a Vermont lake would be able to hold more dissolved oxygen.
C.) Water evaporates more slowly from Vermont lakes, leaving more dissolved oxygen in them.
D.) More rain falls in Florida in summer, diluting the dissolved oxygen in the lake.
Answer:
B
Explanation:
In summer, the temperature of Vermont is lower than that in Florida. When temperature increases, the ability will decrease. So there is more dissolved oxygen in Vermont's lake.
Answer:
B.) The cooler water in a Vermont lake would be able to hold more dissolved oxygen.

Please help ill give you 5 star and brainliest.
Answer:
Answer is C
Explanation:
Each cell has an identical copy of DNA with enzymes controlling the expression of specific genes leading to a variety of cells
The statements 'each cell has an identical copy of DNA with enzymes controlling the expression of specific genes, leading to a variety of cells' BEST describes how different cell types develop (Option C).
Epigenetics refers to any change in gene expression that does not involve a change in the nucleotide sequence.In an organism, all somatic cells are genetically identical, thereby changes in gene expression are due to epigenetic modifications.These epigenetic modifications include DNA methylation and histone modifications (e.g., histone acetylation, histone methylation, etc).Enzymes that add specific epigenetic marks such as histone acetyltransferases alter the accessibility of transcription factors to chromatin, thereby activating or repressing gene expression.In conclusion, the statements 'each cell has an identical copy of DNA with enzymes controlling the expression of specific genes, leading to a variety of cells' BEST describes how different cell types develop (Option C).

A man has extra digits (six fingers on each hand and six toes on each foot). His wife and their daughter have the normal number of digits (five fingers on each hand and five toes on each foot.) The couple's second child has extra digits. What is the probability that their next (third) child will have extra digits?a. 9/16.
b. 3/4.
c. 1/16.
d. 1/2.
e. 1/8.
Answer:
The correct answer is - option D. 1/2
Explanation:
Extra digits on hands and feet mean an individual has six fingers in each hand and feet, this is known as polydactyly. Polydactyly shows an autosomal dominant type of inheritance pattern.
In this case, the mother is normal so she must be recessive alleles and the first daughter is normal so the father must have a recessive allele which means he is heterozygous.
Cross:
Man = Dd
Woman = dd
Their children :
D d
d Dd dd
d Dd dd
Probability of polydactyl child = 2/4 or 1/2 or 50%

This question is incomplete; the complete part is: what are the independent, dependent, and controlled variables?
Independent variable: ORGANIC AND CHEMICAL FERTILIZERS
Dependent variable: HEIGHT OF PLANT
Controlled variable: Same type of seed, water
Explanation:
Independent variable is the variable that is changed or manipulated by the experimenter. In this question, John wanted to test the effects that organic and chemical fertilizers had on plant growth. Hence, the independent variable is the ORGANIC AND CHEMICAL FERTILIZERS used.
Dependent variable is the variable that responds to changes made to the independent variable. The dependent variable is the variable that is measured in an experiment. In this case, the HEIGHT OF PLANTS MEASURED is the dependent variable.
Controlled variable or Constant is the variable that is kept unchanged throughout the experiment in order not to influence the experimental result or outcome. In this case, the controlled variable is the SAME TYPE OF SEED USED, WATER.

Do you solar cells, wind farms, tidal power, hydropower and thermal energy will solve our future energy needs?
Yes, according to my point of view I strongly believes that solar cells, wind farms, tidal power, hydropower and thermal energy will solve future energy needs.
Which source of energy is common now a days?The most common energy now a days is coal and by burning fossils fuels, we are risking climate change as well as limiting our resources. Supplies won’t last forever especially at the rate we are going. By using sun, wind, and water as sources of energy, we have renewable energy which would not run out anytime as soon as we required. Those energy charges are low cost and solves pollution issues too.
Heat energy has been transferred from one place to another by three main processes and in convection, heat energy has been carried by the movement of particles of matter. In conduction, heat is transferred by particles vibrating. In radiation, heat is carried directly by electromagnetic waves.

Suppose we stock a pond with 100 fish and note that the population doubles in the first year (with no harvesting), but after a number of years, the population stabilizes at what we think must be the carrying capacity of the pond: 2,000 fish. Growth seems to have followed a logistic curve. a. What population size should be maintained to achieve maximum yield, and what would be the maximum sustainable fish yield? b. If the population is maintained at 1,500 fish, what would be the sustainable yield?
Answer:
Explanation:
From the given information,
The first process is to determine the initial growth rate by using the formula:
[tex]R_o = \dfrac{In(2)}{t_d}[/tex]
where;
The initial growth rate(constant) = [tex]R_o[/tex] ; &
the doubling time = [tex]t_d[/tex] = 1 year
[tex]R_o = \dfrac{In(2)}{1 \ year}[/tex]
[tex]R_o[/tex] = 0.693 / year
Now, we move up to the net stage to find the growth constant by using the formula:
[tex]r = \dfrac{R_o}{(1 - \dfrac{N_o}{K})}[/tex]
where;
[tex]N_o[/tex] = population of fish in the pond = 100
[tex]R_o[/tex] = The initial growth rate(constant) = 0.693 /year
K = carrying capacity = 2000
Then;
[tex]r = \dfrac{0.693 \ /year }{(1 - \dfrac{100}{2000})}[/tex]
[tex]r = \dfrac{0.693 \ /year }{(1 - 0.05)}[/tex]
[tex]r = \dfrac{0.693 \ /year }{(0.95)}[/tex]
r = 0.730 / year
a)
Now, the maximum yield can be evaluated by using the expression:
[tex]= \dfrac{rk}{4}[/tex]
[tex]= \dfrac{0.730 \times 2000}{4}[/tex]
= 365 fish per year
Also, the maximum sustainable yield is said to be half of the carrying capacity suppose that the population growth obeys logistic curve;
i.e.
[tex]N' = \dfrac{1}{2} \times 2000[/tex]
N' = 1000 fish
b)
If the population is maintained at 1500 fish;
The sustainable yield can be calculated by using the formula:
The Sustainable yield = [tex]r\times N (1 - \dfrac{N}{K})[/tex]
The Sustainable yield = [tex](0.730/ year ) (1500) (1 - \dfrac{1500}{2000})[/tex]
The Sustainable yield = 1095 × 0.25
The Sustainable yield = 273.75 fish per year
The Sustainable yield ≅ 274 fish per year
Population size should be maintained to achieve maximum yield and Sustainable yield if population is maintained at 1,500 fish are 364.7 , 273.525 fish per year
Sustainable yield:Given that;
Stock in start = 100 fish
Double in 1 year
Capacity of pond = 2000 fish
Find:
Population size should be maintained to achieve maximum yield
Sustainable yield if population is maintained at 1,500 fish
Computation:
Growth rate = ln₂ / 1
Growth rate = 0.693 per year
With no growth constraint r = [tex]\frac{0.693}{1-\frac{100}{2000} }[/tex]
With no growth constraint r = 0.7294 per year
A. Population size should be maintained to achieve maximum yield = [tex]\frac{0.7294 \times 2000}{4}[/tex]
Population size should be maintained to achieve maximum yield = 364.7 fish per year
B. Sustainable yield if population is maintained at 1,500 fish = [tex][(0.7294))(1500)][1-\frac{1500}{2000} ][/tex]
Sustainable yield if population is maintained at 1,500 fish = 273.525 fish per year

What are the 3 domains and 6 kingdoms
The three domains are Archaea, Bacteria, and Eukarya, and the six kingdoms are Archaea, Bacteria, Protista, Fungi, Plantae, and Animalia.
In biological classification, the three domains are the highest level of organization for categorizing living organisms. They represent broad groups based on fundamental differences in cell structure, biochemistry, and evolutionary history.
Archaea: This domain includes prokaryotic microorganisms known as archaea. They are distinct from bacteria and eukaryotes, and often live in extreme environments like hot springs, deep-sea vents, and salt flats. Archaea have unique molecular and genetic features that distinguish them from other organisms.
Bacteria: This domain consists of prokaryotic microorganisms called bacteria. They are found in a wide range of habitats and exhibit diverse metabolic capabilities. Bacteria play important roles in various ecological processes and have both beneficial and harmful impacts on humans.
Eukarya: This domain includes all eukaryotic organisms, which are characterized by having cells with a membrane-bound nucleus and other membrane-bound organelles. Eukarya encompasses a wide variety of organisms, including protists, fungi, plants, and animals.
The six kingdoms further classify organisms within the Eukarya domain:
Archaea: This kingdom consists of archaea, which are prokaryotic microorganisms that live in extreme environments.Bacteria: This kingdom includes bacteria, which are prokaryotic microorganisms found in various habitats.Protista: This kingdom encompasses diverse eukaryotic organisms that do not fit into other kingdoms. It includes unicellular organisms like amoebas, paramecia, and algae.Fungi: This kingdom comprises multicellular eukaryotic organisms that obtain nutrients through absorption. It includes organisms like mushrooms, yeasts, and molds.Plantae: This kingdom includes multicellular eukaryotic organisms that are capable of photosynthesis. It consists of plants, including mosses, ferns, gymnosperms, and flowering plants.Animalia: This kingdom encompasses multicellular eukaryotic organisms that are heterotrophic and capable of locomotion. It includes a vast array of animals ranging from sponges to insects, fish, birds, mammals, and humans.These domains and kingdoms provide a hierarchical framework for classifying and organizing the incredible diversity of life on Earth based on shared characteristics and evolutionary relationships.

a. the primary transcript
b. the mRNA
c. at least one of the lariats
d. the poly(A) tail.
e. exon 1
f. all exons
g. some introns
Answer:
a. the primary transcript
Explanation:
The first step in RNAm maturation is the modification of the 5' end of the transcript via the addition of a structure called a cap or 7-methyl guanosine cap. The enzymes responsible for the formation of this cap are recruited to the phosphorylated C-terminal domain after the addition of the first twenty to thirty nucleotides of ARN. The formation of the cap is started by the addition of a GTP molecule oriented inversely to the 5' end nucleotide on RNA. Then methyl groups are added to this G residue and to the ribose forms of one or two nucleotides located on the 5' end. All these reactions take place in the nucleus when the mRNA is found as a primary transcript.
