(b) Discuss the role of carbohydrate metabolic pathways in regulation of blood sugar levels

Answer:

B: only amino acids join together with peptide bonds to form proteins.

Amino acids are glycine and leucine, which are composed of carbon, hydrogen, oxygen, and nitrogen. Carbon, hydrogen, and oxygen make up carbohydrates, which can be either little or big molecules, hence option B is correct.

The building blocks that makeup proteins are polymeric molecules made up of a chain of amino acids. The biological role of galactose, mannose, fructose and ribose is also significant.

The most prevalent monosaccharide in living things is glucose, which also serves as a structural support system and an enzyme to catalyze chemical processes.

Therefore, the amino group of the additional amino acid creates a peptide bond with the polymer's carboxylic acid group, hence option B is correct.

Your question is incomplete, most probably the complete question is:

Why is sustainable use important?

Answer:

They are very versatile and have many different functions in the body, as listed below: Act as catalysts. Transport other molecules. Store other molecules.

Explanation:

Answer: The plant would not be able to transport nutrients and water.

Explanation: PHLOEM and Xylem are the transport system in plants, necessary for carrying nutrients from the leaves to other parts and water from the roots upwards respectively. So destruction to the cambium would lead to the destruction of these vascular bundles.

The fraction of the lamp's light intensity at the plant is 51.22, or 0.512 to three decimal places.

The light intensity of the lamp at a distance of 14 cm can be calculated using the inverse-square law, which states that the intensity of light decreases as the square of the distance from the source increases.

The equation for the inverse-square law is:

I = I0/(d²)

where;

Assuming that the lamp is a point source of light and that the light is evenly distributed in all directions, we can use I0 to represent the total light energy emitted by the lamp and calculate it using the surface area of a sphere with radius 14 cm, which is given by:

A = 4πr² = 4π(0.14m)² = 0.246 m²

Therefore, the total light energy emitted by the lamp is:

I0 = P/A

where;

Assuming that the lamp has a power of 100 W, we can calculate I0 as:

I0 = 100/0.246 = 406.5 W/m²

Now we can calculate the light intensity at the plant, which is located at a distance of 14 cm = 0.14 m from the lamp:

I = I0/(d²) = 406.5/(0.14²) = 20832.6 W/m²

To calculate the fraction of the lamp's light intensity at the plant, we need to divide I by I0:

fraction = I/I0 = 20832.6/406.5 = 51.22

Cellular respiration and photosynthesis are mutually dependent as cellular respiration is the process by which cells break down glucose to release energy while photosynthesis is the process by which plants use light energy to make glucose.

Both processes are required for the survival of life. Photosynthesis produces oxygen, which is used by animals and plants, for cellular respiration. On the other hand, cellular respiration produces carbon dioxide which is used by plants, for photosynthesis.

Cellular respiration and photosynthesis are mutually dependent. This interdependence is shown below:-

6CO₂ + 6H₂O + energy (sunlight) → C₆H₁₂O₆ + 6O₂ (photosynthesis)

C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy (cellular respiration)

Therefore, cellular respiration and photosynthesis are complementary processes that help in the circulation of matter and energy within the ecosystem. Photosynthesis generates food and oxygen for animals, which in turn release carbon dioxide for plants to use in the process of photosynthesis.

The correct answer is - chloroplasts

Explanation:

Plants or autotrophs contain exceptional organelles considered chloroplasts that traps light and use it to use carbon dioxide and water into sugar and oxygen. Living organisms without chloroplasts can not make their own food.  

Chloroplasts look like oval, flat circles. Like mitochondria, they also have two membranes. The whole organelle encased by the outer membrane. The inner membrane contains stroma, a thick fluid, which makes up the vast majority of the chloroplast's volume. Dispersed all through the stroma are piles of empty plates called grana that contain chlorophyll, which traps sunlight based on the intensity for use during photosynthesis.

Protein is the amino acid chain that was made in translation.

Translation is the process by which ribosomes in the cytoplasm or endoplasmic reticulum make proteins after the process of converting DNA to RNA in the cell's nucleus, as defined by molecular biology and genetics. Gene expression refers to the entire process.

The process of translating mRNA into the chain of amino acids that makes up the produced protein occurs on ribosomes in the cytoplasm of the cell. The ribosome is a complex molecule made up of numerous ribosomal RNA molecules, numerous proteins, and both tiny and big subunits.

To test the claim that an increased concentration of algae has a negative effect on the number of aquatic invertebrates in an ecosystem, researchers can conduct the following investigations:

Correlation study: Researchers can collect data on algae concentration and the abundance of aquatic invertebrates across different locations within the ecosystem.

By analyzing the data, they can determine if there is a consistent negative correlation between algae concentration and the number of invertebrates.

Manipulative experiment: Researchers can establish controlled mesocosms or enclosures where they can manipulate the concentration of algae.

They can create treatments with varying levels of algae and monitor the response of aquatic invertebrates over time.

This will help determine if an increased concentration of algae directly affects the abundance and diversity of invertebrates.

Observational study: Researchers can conduct long-term observations in ecosystems with varying levels of algae concentration.

They can document changes in the population dynamics, behavior, and species composition of aquatic invertebrates in relation to changes in algae concentration.

These investigations will provide empirical evidence to assess the impact of increased algae concentration on the number of aquatic invertebrates, helping to validate or refute the claim.

Answer: Therefore, there will be 15,625 bacteria after 72 hours.

Explanation:

Let N(t) be the number of bacteria at time t. The rate of change of bacteria is proportional to the number of bacteria present, so we have:

dN/dt = kN

where k is the constant of proportionality.

Using the initial condition N(0) = 20, we can solve for k:

N(0) = 20

N(t) = N(0)e^(kt)

50 = 20e^(8k)

ln(50/20) = 8k

k = ln(5/2)/8

Now, we can find N(72):

N(72) = 20e^(72k)

N(72) = 20e^(9ln(5/2))

N(72) = 20(5/2)^9

N(72) = 15625

Therefore, there will be 15,625 bacteria after 72 hours.

The magnitude of the electric field in the membrane is 8.75 x 10⁶ V/m.

The magnitude of the electric field in the membrane is 8.75 x 10⁶ V/m.

The given values are:

Thickness of the cell membrane = d = 8.0 x 10⁻⁹ m

Potential difference across the membrane = V = 0.070 V

The electric field E is given by the formula: E = V/d

The magnitude of the electric field in the membrane is 8.75 x 10⁶ V/m.

A cell membrane is made up of two layers of lipid molecules, which are arranged in a specific way that separates the inside and outside of the cell. The inner and outer surfaces of a cell membrane carry a negative and a positive charge, respectively. Because of these charges, a potential difference of about 0.070 V exists across the membrane.

The thickness of the cell membrane is 8.0×10⁻⁹ m. To determine the magnitude of the electric field in the membrane, we use the formula:

E = V/d

where E is the electric field, V is the potential difference, and d is the thickness of the membrane.

Substituting the given values, we get:

E = 0.070 V / 8.0×10⁻¹⁹ m E = 8.75 x 10⁶ V/m

Therefore, the magnitude of the electric field in the membrane is 8.75 x 10⁶ V/m.
