Tay Sachs disease is caused by a type mutation called frameshift mutation. It alters all protein sequence downstream of the mutation site.
What is a mutation?A mutation is any alteration in the genetic material (DNA) of the genome of a particular organism.
A frameshift mutation is a type of mutation capable of changing all the Open Reading Frame (ORF) of a protein, thereby altering its functional and structural properties.
Tay Sachs disease is caused by a frameshift mutation in the HEXA gene located on chromosome 15, which leads to a defective protein and faulty cellular transport of beta-hexosaminidase.

What is the entire object shown in the image?
A. prokaryote
B. eukaryote
C. chloroplast
D. mitochondrion
Answer:
Chloroplast
Explanation:
The organelle is chloroplast because chloroplast is an organelle that contain chlorophyll which is a green pigment or photosynthetic pigment that the plant uses for photosynthesis. It captures light energy from sunlight and it has nucleus, stroma, thykaloids, RIBOSOMES, starch granules, granum, outer membrane e.t.c. it trap light energy from sun and engage in photosynthesis along with water and carbondioxide to produce starch.
b. Why is there a huge demand of professionals in the field of agriculture
Answer:
There is an increase in demand for higher quality and quantity of food and other products.
Explanation:
There is an increase in demand for higher quality and quantity of food and other products. So, there is a huge requirement for technological innovation. Investment is needed in research and development to develop crops that are pesticide-free, resistant to disease, and able to face various weather conditions. Vertical farming and carbon-capture technology can be used to meet growing world food demands.
Which of the following is a chemical property of iron?
A. Iron corrodes in moist air.
B. Iron is soft when pure.
C. Iron melts at 1808 K.
D. Iron's density = 7.874 g/cm3
Answer:
A
Explanation:
Iron corrodes in moist air. When iron gets exposed to air, it reacts with oxygen molecules to form rust. Rust degrades the quality of iron. Therefore, methods of protection from rusting like, Barf's protection, Sacrificial protection etc. are carried out.
Iron corrodes in moist air is a chemical property of iron. Hence the correct option is A.
A chemical property of iron is its ability to corrode in moist air. Corrosion is a chemical reaction that occurs when iron reacts with oxygen and moisture in the air, resulting in the formation of iron oxide, commonly known as rust. This chemical property of iron is due to its reactivity with oxygen and can lead to the degradation and weakening of iron-based materials over time.
Corrosion is a chemical process that involves the reaction of a metal with its environment, typically in the presence of moisture or oxygen. In the case of iron, when it comes into contact with moist air, it undergoes a chemical reaction known as oxidation. This reaction causes the formation of iron oxide, commonly known as rust.
The corrosion process begins when iron reacts with oxygen in the air, a process called oxidation. This reaction leads to the formation of iron(III) oxide, which is commonly seen as the reddish-brown coating known as rust. The presence of moisture accelerates the corrosion process by providing the necessary medium for the reaction to occur.
Hence the correct option is A.

Answer:
When a catalyst is present in a biochemical reaction, what is not expected is that the reaction requires more energy than normal (option b).
Explanation:
A catalyst is a substance used to facilitate a chemical reaction, decreasing the reaction time. Unlike a reagent, the catalyst retains the same amount of mass at the end of the reaction.
In a biochemical reaction, the use of a catalyst not only accelerates the reaction, but also decreases the amount of energy required by the process. An example of a biological catalyst is enzymes, specialized proteins that facilitate metabolic reactions.
The other options can be expected with the use of a catalyst, due to:
a. One of the functions of the catalyst is to decrease the amount of energy needed in a reaction.
c. Catalysts are substrate specific.
d. Catalysts work in a specific pH range.

Are microscopic and macroscopic ecosystems affected by limiting factors differently? Explain.
Answer:
No.
Explanation:
No, the microscopic and macroscopic ecosystems can't affected by limiting factors differently because both required the same factors for their survival and growth. The factors required by every organism in both microscopic and macroscopic ecosystems such as food, water, habitat, and reproduction. If these factors are limited then the population of the organisms will be lower. So both affected the same due to limiting factors.

Both animal and plant cells are eukaryotic cells. Membrane bound organelles are a characteristic feature of eukaryotic cells.
What are Membrane bound Organelles?Prokaryotic cells however do not posses membrane bound organelles.
The nucleus is frequently referred to as the eukaryotic cell's command center. This is so because it has the knowledge required to produce proteins.
Because every component of the cell need proteins to function, the nucleus regulates the actions of the other organelles by housing the genetic instructions for making proteins.
