Question 1
1. What is the nickname for DNA?
The life giver molecule
O The blue print of life
The backbone of life
O The helix that support life
The nickname for DNA is "The blueprint of life. Therefore, option (B) is correct.
What is DNA?DNA (Deoxyribonucleic acid) is a molecule that carries genetic information in all living organisms, from simple bacteria to complex animals and plants. It is a double-stranded helix made up of nucleotides that contain four nitrogenous bases: adenine (A), thymine (T), cytosine (C), and guanine (G).
The sequence of these bases determines the genetic code that governs the development, growth, and function of all living things. DNA is essential for passing on genetic traits from one generation to the next, and it plays a vital role in the evolution and diversity of life on Earth.

Explain how concern for profits shapes business decisions.
Answer:
Businesses/companies will often compromise the quality of a product or service in order to make a profit. If a company uses cheap supplies to make a product, they will make more profit from it.
Here is an example:
Imagine you are making soap-making company. You use all organic ingredients which are very expensive. Let's say it takes $6 for you to make one bar of soap. If you sell your bars for $10, then you will make a $4 profit from each bar sold.
Now let's say another company starts making soap. It looks and feels almost exactly like yours. HOWEVER, this company uses artificial ingredients. It takes them only $3 to make a bar of soap, and they sell their soap on "sale" for $9. Not only will they likely sell more soap than you because their soap is cheaper, but they will make a $6 profit from each bar sold-- two more dollars per bar than you.
The same can be true the other way around of course. If a business realizes that nobody is buying their product because it is so poorly made, then they will improve the quality of their product in order to increase their sales.

How is the availability of needed natural resources affected by human activities?
Answer:
Humans take natural resources for things such as manufacturing oil, building, making plastics, etc. For example, harvesting trees to cut and make planks of depletes the Earth of a necessary resource for filtering oxygen.
Numerous human activities such as overpopulation, pollution, the burning of fossil fuels, and deforestation have an adverse effect on the physical environment.
What are natural resources?Natural resources are those resources that we get from nature. These resources are free, but they are not available for a lifetime.
The availability and quality of natural resources have been significantly impacted by human activity. Petroleum products are daily used in enormous quantities by companies and cars.
Around 40% of the electricity in the world is produced by coal-fired power plants. The reserves of these finite resources are being depleted by the extensive usage of fossil fuels.
Therefore, climate change, soil erosion, poor air quality, and undrinkable water have all been brought on by changes like these.

Which of the following statements is false?
a. Performing a cross to produce an F1 generation can be used to show if an allele is dominant.
b. The F1 generation is always hybrids.
c. An F1 cross produces an F2 generation.
d. All of the offspring of a cross may exhibit the same trait.
Answer:
d
Explanation:
cannot be same if they produce f2 will take time to be the same!
Thank you!
The correct answer is d. All of the offspring of a cross may exhibit the same trait as it is only in purebred.
The phenomenon of dominant phenotypes springing up from the allele interactions exhibited on this go is called the precept of uniformity, which states that every one of the offspring from ago in which the mother and father fluctuate through best one trait will seem identical.
What are Inherited traits?Inherited traits tendencies encompass matters along with hair color, eye color, muscle structure, bone structure, or even functions just like the form of a nose. Inheritable tendencies are tendencies that get exceeded down from era to the subsequent era. This would possibly encompass such things as passing pink hair down in a family.

Give differents between lytic and lysogenic cycles
Answer:
the spread of the viral DNA
Explanation:
The difference between lysogenic and lytic cycles is that, in lysogenic cycles, the spread of the viral DNA occurs through the usual prokaryotic reproduction, whereas a lytic cycle is more immediate in that it results in many copies of the virus being created very quickly and the cell is destroyed.

Distinguish between gaseous exchange and respiration
Answer:
Respiration is the process in which food is oxidized to release energy. Complex organic compounds are converted into simpler ones, e.g glucose into CO2 water and energy released. Gaseous exchange is the diffusion of gases from a region of higher concentration to a region of lower one.
Explanation:
Breathing is the physical process by which air is passed on a gaseous exchange surface i.e. ventilation of the gaseous exchange surface. It involves Inhalation and Exhalation.
Gas/Gaseous exchange is the process whereby gasses diffuse across a gaseous exchange surface. In humans, oxygen diffuses from the inhaled air into the blood and carbon dioxide diffuses from the blood into the exhaled air. The gaseous exchange surface here being the Alveoli.
Respiration is the metabolic process whereby organic molecules are broken down to release energy in the cells. In humans, this process takes place inside the mitochondria of cells. Aerobic respiration requires oxygen whereas qnqerobic respiration takes place in absence of oxygen.

Which process produces four genetically different gamete cells?
A. Mitosis
B. Meiosis
Answer:
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.
Answer:
B. Meiosis
Explanation:
Specifically, meiosis creates new combinations of genetic material in each of the four daughter cells. These new combinations result from the exchange of DNA between paired chromosomes. Such exchange means that the gametes produced through meiosis exhibit an amazing range of genetic variation.
