If I am understanding correctly, the first thing they are asking you to do is match nitrogen bases.
Adenine (A) always pairs with thymine (T), and guanine (G) always pairs with cytosine (C).
Then, whichever are the double strands, cut them out and put them into you notebook. (I am not sure where the notebook is, but I am assuming you know)
Then in the speech bubble next to the picture of Chargaff- talk about his rule.
What does the rule mean?
What does the rule explain?
How is the rule demonstrated?
Lastly, finding percents. What percent of the pairs has Adenine in them?
For example:
If I look at this pairing below
A →T
T→ A
G →C
C→ G
50% of the pairs include Adenine.
Hope I helped! Comment if you have questions about my answer :)
Answer:
If the sequence of nitrogenous bases of a DNA strand is ATCTAGGCCG, the complementary strand would be TAGATCCGGC, with a percentage of guanine 30%, cytosine 30%, adenine 20% and thymine 20%, according to Chargaff's rule.
Explanation:
DNA is made up of sequences of nitrogenous bases, which are adenine (A), guanine (G), thymine (T) and cytosine (C). The bases of one strand are matched with the bases of another, according to the complementarity of nitrogenous bases, where:
Adenine is complemented with Thymine A=T Guanine is complemented with Cytosine G≡CThe image shows a DNA chain whose chain is complementary:
DNA Strand given Complementary Strand
Adenine Thymine
Thymine Adenine
Cytosine Guanine
Thymine Adenine
Adenine Thymine
Guanine Cytosine
Guanine Cytosine
Cytosine Guanine
Cytosine Guanine
Guanine Cytosine
Therefore, in a DNA molecule there is as much adenine as thymine, and an equal amount of cytosine and guanine. In this example there are 4 molecules of adenine, 4 molecules of thymine, 6 guanines and 6 cytosines.
The proportion or percentages of nitrogenous bases can be calculated according to Chargaff's rule.
Chargaff was able to establish that in a DNA molecule the ratio of purine:pyrimidine of 1:1, so there must be the same amount of thymine as adenine and a similar amount of guanine for the cytosine, according to the complementarity of bases.
Taking into account the law of the base pair, if in a DNA chain there is 30% of Adenine, in the molecule there is:
Guanine 30%
Cytosine 30%
Adenine 20%
Thymine 20%
Total ..... 100%

Answers
The amino acid's R group has the most impact on the entire protein structure.
Amino acids are tiny particles that serve as the foundation for proteins. Proteins provide structural support within the cell and participate in numerous critical chemical reactions. Each protein is a compound composed of various combinations of 20 different kinds of more straightforward, smaller amino acids. Protein molecules are three-dimensional chains of amino acids.
R groups come in various forms, sizes, reactivities, and charges. As a result, amino acids can be classified according to the chemical properties of their substituent groups.

cellular energy, most often in the form of atp, is required to move substances across cell membranes in which one of these processes?
Answers
Active Transport is the mechanism by which molecules are moved across cell membranes.
It requires cellular energy which most frequently is in the form of ATP.
What is Active Transport?
Active transport is the process of movement of substances from a lower concentration to a higher concentration, i.e., against the concentration gradient, with the expenditure of energy in the form of ATP. Active transport occurs against the concentration gradient while other transport processes like diffusion facilitated diffusion and osmosis occur along the concentration gradient and without the involvement of ATP.Thus, cellular energy is required in the process of active transport to move substances across cell membranes. And, ATP is the most frequently used energy in this process.

Centromere
Answers
One half of a duplicated chromosome is called Chromatid. The correct option is B.
Thus, A chromatid is the name for the duplicated half of a chromosome. The chromosome is duplicated during DNA replication, creating two identical copies known as sister chromatids.
The centromere, a particular area, is what holds these sister chromatids together. A complete set of DNA molecules or genetic material can be found in each chromatid. During cell division, the sister chromatids split apart to form individual chromosomes, which are then dispersed to the daughter cells.
Contrarily, the telomeres are specialized structures found at the ends of chromosomes that aid in maintaining the DNA's integrity during replication and guard against deterioration.
Thus, One half of a duplicated chromosome is called Chromatid. The correct option is B.

Neuroplasticity is a broad term related to the brain's capacity to alter, modify, and adapt its function and structure across people's lives and in response to stimuli.
Individual differences in brain function and structure contribute to the variability observed in neuroplasticity mechanisms, which also show significant differences across individuals.

Ecological succession are the natural gradual changes in the types of species that live in an area we may refer to ecological succession as either primary or secondary the graphic represents an example of primary succession which begins in an area that has no living organisms present. notice in the illustration the first organisms to inhabit the area undergoing succession are lichens and Moss. what a biotic feature restricts the growth of more diverse plants in this area.
Answers
Answer:
The lack of topsoil inhibits the growth of more diverse organisms in the region.
Explanation:
Following catastrophic or destructive events, primary succession occurs with the growth of the microorganisms. Here a non-habitable area is exploited by a colonizing organism. For instance, lichens and moss break down rock and decompose to add nutrients to sediment creating topsoil.
Ultimately, these make the environment more livable by nutrient cycling, weathering, etc., which ushers in secondary succession. Here over time, the cultures become more dynamic, more diverse and an ever-larger food web.
In the first stage of primary succession after there has been a volcanic eruption, the soil quality will be poor. Plants that are good soil formers, such as lichens and moss, will improve the soil. Over time, with increasing plant diversity, rich soil with humus will form that will improve water retention. Taller and more diverse plants will allow for more filtered sunlight and more moderate soil temperatures.

The effect of population distribution and density on the environment and natural resources is known as.
Answers
The effect on the environment and the natural resources by population distribution and density is termed Carrying capacity.
Carrying capacity refers to a species' average population size in a particular habitat. The environment can regulate a species' population size by providing enough food, shelter, water, and mates. If these needs are not met, the population will decrease until the resource is replenished.
Population composition can be characterized by the pattern produced by age distribution and gender ratio at different scales and locales. The population's distribution and density both show the influence of demographic composition.
Hence, the effect of population on its environment is called as carrying capacity as this will tell us that for how long will the environment be able to sustain that population size.

The cell membrane has____. a) polar heads on the outside and nonpolar fatty acids on the inside b) nonpolar fatty acids on the outside and a polar heads on the inside c) polar heads on both inside and outside d) nonpolar fatty acids on both inside and outside
Answers
Answer:
a) polar heads on the outside and nonpolar fatty acids on the inside
Explanation:
The cell membrane is made up of phospholipids arranged in a bilayer, where hydrophilic polar (negatively-charged) heads of phospholipids interact with water molecules (i.e., aqueous surrounding media). Moreover, non-polar (uncharged) fatty acid tails are hydrophobic because they cannot be dissolved in water. Thus, the bilayer cell membrane is a structure where non-polar fatty acid chains are localized in the inner region (away from the water), while hydrophilic phosphate heads face outward, interacting with water on both sides of the cell membrane.
