Answer:

The inner mitochondrial membrane contains proteins involved in the electron transport chain. This chain releases energy that is then used to generate an electrochemical gradient, which is subsequently used to synthesize ATP

Explanation:

Mitochondria are membrane-bound organelles that have an inner membrane separated from an outer membrane by the intermembrane space. Moreover, the mitochondrial matrix is located within the inner membrane. The inner mitochondrial membrane contains proteins involved in the electron transport chain and ATP synthesis. Oxidative phosphorylation (electron transport chain) is the third stage of cellular respiration in aerobic organisms in which ATP is generated by transferring electrons from NADH or FADH2 to O2 by a series of electron carriers located in the inner mitochondrial membrane. The trans-membrane complexes of electron carriers are multiprotein enzyme complexes (I–V) and electron carriers (i.e., coenzyme Q10 and cytochrome c) required for the communication between complexes. The electron transport chain is coupled to proton transfer from the matrix out to the intermembrane space, thereby generating a proton gradient which is then used by ATP synthases to synthesize ATP​.

b. methylation.

Explanation:

Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments.

Genome editing can be defined as a high-tech process which avail scientists the opportunity or ability to remove (delete), replace and insert Deoxyribonucleic Acid (DNA) sequence in a living organism such as bacterias, animals, plants etc in order to correct a genetic disorder and to improve on their physical and chemical conditions.

Transcription can be defined as a process which typically involves re-writing the informations contained within a Deoxyribonucleic Acid (DNA) into a Ribonucleic Acid (RNA) by enzyme RNA polymerase.

Hence, DNA regions that are transcriptionally silenced by hypercondensation have often undergone a modification of their cytosine residues termed methylation.

For example, CpG island methylation transcriptionally silences about 650 to 800 genes in patients suffering from colorectal cancer.

Therefore, required mass of insert DNA is 30 ng

Explanation:

DNA ligation is the process of joining two DNA fragments together through the action of an enzyme for example DNA ligase. The vector DNA often a plasmid is used to insert a desired DNA sequence into a host cell DNA.

The formula for the calculation of required insert DNA mass is given below:

Required mass insert (ng) = desired insert/vector molar ratio x mass of vector (ng) x ratio of insert to vector lengths

Desired insert/vector molar ratio = 3 : 1

Mass of vector = 30 ng

Ratio of insert vector lengths = 4 : 12 = 1 : 3

Required mass of insert DNA = 3/1 × 30 ng x 1/3 = 30 ng

Therefore, required mass of insert DNA is 30 ng

Answer:If increases in supply do not keep pace with growth in demand, food prices rise, attracting resources into food production. If supply grows faster, food prices and farm incomes fall, driving resources out of agriculture. Resources may not move fast enough to correct imbalances.

Explanation:

Answer:

Food production and availability is a problem for many people throughout the world. Many people try to help this problem by trying to provide food for those in need, but this isn't a real advantage to anyone. When people buy more of one a product to donate, it causes an increase in demand that the supply may not be keep up with causing the prices to increase, making it harder for everyone to afford it Even if the supply increases but then produces more than demanded the prices for the particular product will drop, resulting in the farmers not being paid enough, or growing more could lead to the land losing resources faster than normally.

The nutrient which provide more energy is C. Lipids

Among the given options, lipids provide the most energy per unit mass. Lipids, also known as fats, are a concentrated source of energy in the diet. When metabolized, lipids yield approximately 9 kilocalories (kcal) of energy per gram.

Carbohydrates, including sugars and starches, provide approximately 4 kcal of energy per gram. They are a readily available source of energy for the body, particularly for short-term energy needs. Proteins also provide approximately 4 kcal of energy per gram. However, their primary role is not as an energy source but rather as the building blocks for tissues, enzymes, and other important molecules in the body.

Vitamins, on the other hand, do not provide significant energy. They are essential for various biochemical processes in the body but do not contribute directly to energy production.

It is important to note that while lipids provide the most energy per gram, the overall balance and variety of nutrients in a diet are crucial for maintaining optimal health. Nutrient needs vary based on individual factors, such as age, sex, activity level, and overall health goals. Therefore, Option C is correct.

To answer this question, we have to consider what happens to our cells when they face different amounts of salt or solutes in their surroundings: what happens when the solutes' concentration is equal both inside them and outside them (isotonic), what happens when the solute concentration is higher outside with respect to their inside (hypertonic), and what happens when the solute concentration is lower outside with respect to their inside (hypotonic), so we can use the picture below to see it graphically.

In these pictures, we can see that when the cells of an organism face a hypertonic media (when there are high concentrations of solutes), they dehydrate because of water loss, so they shrink, and when those cells are exposed to low concentrations of solute, with respect to their inside, they absorb water, so they swell.

Having this clear, we can say that if a saltwater animal exposes to higher concentrations of solutes, its cells will shrink or experience plasmolysis, as stated in the third answer option.

The answer is gene flow. Gene flow is the transfer of genes or alleles from one population to another due to the movement of individuals or their gametes (reproductive cells).

What is Gene?

A gene is a specific sequence of DNA that encodes a particular protein or RNA molecule, which in turn determines a specific trait or characteristic in an organism. Genes are the fundamental units of heredity and are passed down from parents to their offspring during reproduction.

As humans migrate around the globe, they can bring their genes with them and introduce them into new populations or take genes from one population and introduce them into another, thus affecting the genetic makeup of those populations. This movement of genes is known as gene flow.

Answer:

Explanation:

When a meal containing fried fish and toast bread is consumed, it goes through a series of processes in the digestive system of a human. Here's a general description of how the components are processed:

1. Mouth: The process of digestion begins in the mouth. Chewing breaks down the toast bread and fish into smaller pieces, while saliva mixes with the food to start the breakdown of carbohydrates.

2. Esophagus: The chewed food, now called a bolus, is swallowed and travels down the esophagus through peristaltic contractions. The esophagus carries the food to the stomach.

3. Stomach: The stomach is responsible for further mechanical and chemical digestion. It mixes the food with stomach acid and digestive enzymes to break down proteins. The fried fish is broken down into smaller pieces through mechanical churning.

4. Small Intestine: The partially digested food leaves the stomach and enters the small intestine. Here, bile from the liver and enzymes from the pancreas break down fats, while other enzymes continue the breakdown of proteins and carbohydrates. Nutrient absorption occurs through the walls of the small intestine and is facilitated by small finger-like projections called villi.

5. Large Intestine: Any remaining undigested food, as well as water and electrolytes, pass into the large intestine. The large intestine absorbs water and electrolytes while forming waste material known as feces.

6. Rectum and Anus: The feces are stored in the rectum until elimination through the anus occurs during a bowel movement.

Throughout this process, various digestive enzymes and gastric juices are secreted at different stages to facilitate the breakdown and absorption of nutrients. The fried fish and toast bread are broken down into smaller molecules, such as proteins, carbohydrates, and fats, which are then absorbed into the bloodstream to provide energy and nourishment for the body.
