Why is it said that natural selection acts on phenotypes rather than on the genetic material of organisms?
Answer:
It's because an organism's phenotype, or physical traits, are what truly decide whether it can reproduce and pass on its genotype to the following generation.
Because the phenotype of an organism represents the alleles that are actually expressed in that organism, natural selection affects that phenotype.

Question 1 1) The mass of a ribosome is 210 x 10-18 g. Assume it is a perfect sphere with a radius of 0.O1um. Calculate the sedimentation coefficient (SLin Svedbergs in a medium of viscosity (n) 1.59 poise (g/cm/s): T=3.142_ 2) The ribosome is pelleted at an angular velocity of 4188 rad/s using a rotor of radius 10 cm. What g-force (centrifugal force) is applied to the particle? 3) Succinate dehydrogenase (SDH) is used as a marker for mitochondria: A cell is fractionated by differential centrifugation and the distribution of SDH calculated providing the partial data below: fraction 2,500g pellet 70,00Og pellet 300,000g pellet cytosolic ASDH 1250 ISDH % protein 30 RSA 2250 20 750 15 350 35 (a) Complete the information in columns 3 and 5_ (b) Plot the data as a bar histogram with RSA on V-axis and % protein on X-axis (c) Which fraction is enriched in the mitochondria?
The sedimentation coefficient of the ribosome is 78.5 S. The centrifugal force applied on the particle is 377.6 x \(10^{-12}\) N, therefore, the g-force applied to the particle is 1,960,292 g.
How do you calculate the sedimentation coefficient of the particle?We can apply the following formula to determine the ribosome's sedimentation coefficient:
S = (2/9) * (r^2) * (p - f) / n
where:
f = density of the solvent (assumed to be water) = 1 g/cm3
n = viscosity of the solvent = 1.59 poise = 0.000159 g/cm/s
r = radius of the ribosome = 0.01 um = 0.0000001 cm
p = density of the ribosome = mass/volume = mass / ((4/3) * pi * (r))) = 210 x \(10^{-18}\) g
By entering these values, we obtain:
S = (2/9)* (0.0000001 cm)* (1.407 g/cm3 - 1 g/cm3)* (0.000159 g/cm/s)* (1.407 g/cm2 * 2 *)* = 78.5 S
As a result, the ribosome's sedimentation coefficient is 78.5 S.
How do you calculate the centrifugal force and g-force on the particle?We can use the following formula to get the centrifugal force exerted on the ribosome:
F = m * r * w^2
where: w = angular velocity = 4188 rad/s
m = mass of the ribosome = 210 x \(10^{-18}\) g
r = radius of the rotor = 10 cm
By entering these values, we obtain:
F = 210 x \(10^{-18}\) g x 10 cm x 4188 rad/s / 2 = 377.6 x \(10^{-12}\) N
We may divide this by the acceleration caused by gravity to get the g-force:
g = F/(m*g) = (377.6 x \(10^{-12}\) N)/(210 x \(10^{-18}\) g * 9.81 m/s2) = 1,960,292 g
As a result, the ribosome is subjected to a centrifugal force of 1,960,292 g.

. What sorts of living things are made up of prokaryotic cells?
Bacteria and archaea are the two types of living beings made up of prokaryotic cells.
What are bacteria and archaea?Bacteria and archaea are both prokaryotic and unicellular organisms. This means that they both lack a true nucleus and membrane-bound organelles. The genetic material is present in a long single loop of chromosome, called the nucleoid.
Both bacteria and archaea have a cell wall present outside of the cell membrane. The structural composition of the cell wall is different among them. In bacteria, the cell wall is made up of peptidoglycan (a sugar and protein complex compound) and in archaea, it is made of pure polysaccharides.
Both of these organisms reproduce asexually. They also have flagella for locomotion, pilus for adherence and a capsule outside of the cell wall for protection against conditions like dehydration.

Answer:
nitrogen
Explanation:
Plants use photosynthesis by taking in water and carbon dioxide and releasing oxygen while consuming food (glucose) for itself. Therefore, your answer is nitrogen. No nitrogen is created during this process
Answer:
Nitrogen
Explanation:
Photosynthesis is a process used by autotrophs and producers, like plants, algae, and some bacteria. In this process, water, carbon dioxide and light energy from the sun are turned into glucose and oxygen. The glucose becomes food for the organism, and the oxygen becomes the waste product.
There is no nitrogen involved in photosynthesis. It is not created, and therefore is not a product. The best answer choice is nitrogen
3. How is Acetyl-CoA prsluced during the acrobic oxidation of carbohydrates, and what happens to it? How is it produced during the aerobic oxidation of titty acids, and what happens to it
During the aerobic oxidation of carbohydrates, acetyl-CoA is produced through a series of metabolic reactions known as glycolysis and the citric acid cycle. During the aerobic oxidation of fatty acids, acetyl-CoA is produced through a process called beta-oxidation.
Pyruvate then enters the mitochondria, where it undergoes further processing to produce acetyl-CoA. This conversion occurs through a process called pyruvate decarboxylation, where pyruvate loses a carbon dioxide molecule and combines with coenzyme A (CoA) to form acetyl-CoA. Acetyl-CoA is a key molecule in energy metabolism and serves as a precursor for the citric acid cycle.
During the aerobic oxidation of fatty acids, acetyl-CoA is produced through a process called beta-oxidation. Fatty acids are broken down into two-carbon units, which then combine with CoA to form acetyl-CoA. This process occurs in the mitochondria, where fatty acids are sequentially cleaved into acetyl-CoA molecules. The acetyl-CoA molecules can enter the citric acid cycle to generate energy through oxidative phosphorylation.
Once acetyl-CoA is produced, it enters the citric acid cycle, also known as the Krebs cycle or TCA cycle. In this cycle, acetyl-CoA undergoes a series of enzymatic reactions, resulting in the production of ATP, NADH, and FADH2. These energy-rich molecules are then utilized in the electron transport chain to generate ATP through oxidative phosphorylation.

What is a nitrogen?Nitrogen is the chemical element with the symbol N and atomic number 7. Nitrogen is a nonmetal and the lightest member of group 15 of the periodic table, often called the pnictogens. It is a common element in the universe, estimated at seventh in total abundance in the Milky Way and the Solar System.
Nitrogen is important to the chemical industry. It is used to make fertilizers, nitric acid, nylon, dyes and explosives. To make these products, nitrogen must first be reacted with hydrogen to produce ammonia. This is done by the Haber process.
Nitrogen is important to all living things, including us. It plays a key role in plant growth: too little nitrogen and plants cannot thrive, leading to low crop yields; but too much nitrogen can be toxic to plants [1]. Nitrogen is necessary for our food supply, but excess nitrogen can harm the environment.

3 Describe two pieces of evidence that show that plants cannot make their own food without light.
4 Starch tests show where photosynthesis has taken place. What can you conclude using the evidence from test 1?.
à5 What does the evidence from test 3 show?
1. Animals depend on plants to keep them alive is Plants are producers they take energy from the sun, nutrients from the earth, and water to grow and have their flowers, seeds, and berries.
They also release oxygen, which all animals, including humans, need to stay. Animals are consumers and they all depend on plants for survival.
2. carbon dioxide and water reach the chloroplasts in leaves is Basically the roots consume the water and transports it up the xylem, which gets it to the leaves. Carbon dioxide contacts the chloroplasts in the leaves via a stomata
3. Two pieces of evidence that show that plants cannot make their own food without light. When plants lack light, they don't deliver chlorophyll (the green pigment in plants), and plants can turn pale green to yellow to white. Plant stems become “leggy,” meaning stems become long and thin and appear to be advancing toward the source of light.
The photosynthesis is the only method for synthesizing food. It is commonly believed that about 717.6Kcal energy is required to prepare just 10g of glucose. No energy input no metabolism and therefore no food.How are leaves tested for starch?The existence of starch in leaves can be tested by the Iodine test.
