Mutations can occur in the chromosomes of all types of cells. mutations that are passed on to offspring must occur in ?

Some mutations don't have any noticeable effect on the phenotype of an organism. This can happen in many situations: perhaps the mutation occurs in a stretch of DNA with no function, or perhaps the mutation occurs in a protein-coding region, but ends up not affecting the amino acid sequence of the protein.

Biogeochemical cycles recycle water and natural elements throughout the biosphere to ensure that organisms do not run out of these substances. Thiobacillus denitrificans is a specialized species of bacteria that obtains its energy from carbon dioxide and inorganic compounds such as nitrogen in its environment. It is used in bioremediation of groundwater that contains excess nitrate. How does Thiobacillus denitrificans help bioremediate groundwater?

Thiobacillus denitrificans is a chemolithoautotrophic bacteria which can obtain energy from the oxidation of inorganic compounds like nitrogen, iron or sulphur in their environment. It is an autotrophic denitrifying bacteria that is used in the bioremediation of contaminated groundwater. The process of bioremediation is carried out by the process of denitrification.

Nitrate contamination of groundwater is of high-priority concern. In the process of denitrification by Thiobacillus denitrificans, pyrite acts as the electron donor. Other sulphur minerals also act as electron donors in the process of denitrification and help in bioremediation of the contaminated ground water. The bacteria has also been engineered for nitrate removal in water treatment systems also.

For each phase,describe at least one way mistakes during the cell cycle could result in problems

Ans.

Cell cycle includes a series of events, which leads to DNA duplication, followed by formation of new cells from a parent cell. In humans and other higher organisms, cell cycle consists of four phases, G1 (gap 1), S phase (synthesis phase), G2 phase and M phase (either mitotic or meiotic phase), in which mistakes can occur.

During G1 phase, cell prepares itself to divide and makes proteins, required for DNA synthesis during S phase. Errors occur when cell cannot make sufficient proteins and other necessary raw materials.

During S phase, DNA replication takes place to gets divided into daughter cells. Errors during S phase includes mutations and loss of DNA integrity.

During G2 phase, cell gets prepared for mitotic or meiotic division. Errors that occurred during S phase are repaired during G2 phase. Mistakes in repairing those errors result in problems as they will pass to the new daughter cells through M phase.  

During M phase, separation of duplicated chromosomes into daughter cells occurs. Mistakes that can lead to errors during this phase include chromosomal abnormalities, such as polyploidy or enuploidy.

Which of the following organelles is primarily responsible for the formation of the cell's lysosomes

Answer;

Golgi apparatus or Golgi complex or Golgi bodies

Explanation;

  • Golgi apparatus are also called Golgi bodies or Golgi complex. They are complex vesicles and folded membrane within the cytoplasm of eukaryotic cells.
  • Golgi apparatus are important in the secretion and intracellular transport roles. A major function is the modifying, sorting and packaging of proteins for secretion. They are also involved in the transport of lipids around the cell, and the creation of lysosomes.
  • Therefore, Golgi apparatus are the organelles responsible for the formation of lysosomes, which are organelles that destroy old and worn out cellular organelles.

1. production of needed energy lysosomes 2. production of protein Golgi apparatus 3. flat sacs that package and ship vesicles outside the cell endoplasmic reticulum 4. store foods or pigments mitochondria 5. tubes serving as transportation channels ribosomes 6. contain digestive enzymes plastids

Answer:

The correct answer will be-

1. production of needed energy- mitochondria

2.  production of protein- ribosomes

3.  flat sacs that package and ship vesicles outside the cell- Golgi apparatus

4. store foods or pigments- plastids

5. tubes serving as transportation channels- endoplasmic reticulum

6. contain digestive enzymes- Lysozymes

Explanation:

The cellular organelles perform a different function in a cell. Each organelle carries out distinct and specific functions.

1. Mitochondria- double-membrane organelle which performs the function of ATP synthesis. Since statement mentioned the production of energy, therefore, mitochondria are the correct answer.

2. Ribosomes- the organelle associated with the synthesis of proteins during the translation process. Thus, the ribosome is correct option.

3. Golgi apparatus- organelle is associated with the packaging and modification of the protein to be transported. Thus, the Golgi apparatus is the correct option.

4. Plastids- the organelle which contains pigments and provides color to the structure like green pigment in the chloroplast. Thus, plastid is the correct answer.

5. Endoplasmic reticulum- Orgenelle which are tubular in appearance and carry tmodify the proteins synthesised on the ribosomes. Thus, the endoplasmic reticulum is the correct option.

6. Lysosomes- The orgnelle which contains hydrlytic enezymes which hydrolyse every biomolecule. Thus, the lysosome is the correct answer.

If energy efficiency is improved, the cost of energy would decrease and _____. A)more coal would be available B) less electricity would be used C) homes would cost significantly less D) Energy Star appliances would no longer be necessary

The correct answer is option B

The energy efficiency can be defined as the output of energy to the input of energy.

As the efficiency of energy is increasing then the consumption of electricity will be less because previously the energy was used more due to loss of energy.

But now the energy will not be lost in the form of heat or friction and the cost of energy will be less.

Earth is a closed system in terms of energy.C. There is energy to support life on earth.D. Energy is created but not destroyed in the earth system

Answer: C. There is energy to support life on earth.

The earth receives thermal energy from the sun via. radiation. This energy is captured by chlorophyll pigments of plants and other organisms to conduct photosynthesis. The sunlight energy is necessary for synthesis of food in the form of glucose. The glucose is converted into chemical form of energy as ATP which is required for respiration process in plants. Photosynthesis and respiration both are necessary processes to sustain life of plants, which further support life of other living organisms. Therefore, energy transfer support life on earth.
