Where must a mutation occur if it is to directly affect an amino acid sequence?
Answers
Mutations are modifications to the DNA sequence that can result from radiation or other forms of DNA damage. The amino acid structure of a protein can be altered by mutations that take place in the section of a gene called the "coding region."
Another is that the vast majority of mutations happen in somatic mutations, such as muscle or skin cells, and only have an impact on the cell in which they originate and cells that develop from that cell. Mutations are modifications to the DNA sequence that can result from radiation or other forms of DNA damage. The amino acid structure of a protein can be altered by mutations that take place in the section of a gene called the "coding region."When an organism reproduces sexually, germ-line mutations take place in the egg cells (sperm or eggs) and are passed on to the progeny. Non-reproductive cells experience somatic mutations, which are transmitted through the process of mitosis to daughter cells but not to the progeny during sexual reproduction. High-energy sources like radiation or the presence of environmental chemicals can both result in mutations.

10 differences between animal cells and plant cells
Answers
Answer:
Following are the difference to the given question:
Explanation:
Plant cells have a wall of a cell, while cells of animals wouldn't. Cell membranes offer plants support and shape.Chloroplasts in plant cells do not occur, however, in animal cells. Chloroplasts allow plants can grow things via photosynthesizing.Plant cells typically get a vacuole(s) that is one or even more big, whereas animal cells are vacuous, whether any.Large vesicles assist shape the plant and enable food and water to be store for future use.In animal cells, the storing function takes a smaller part and the vacuoles, therefore, are smaller.A plant cell is square in its structural way and an animal cell is often spherical and irregular.The cell of a plant has a vesicle in its big form which is significantly smaller than the plant cell, as well as the animal cell was the or more vacuoles. In general, a vacuole is a storage area for the cells to store water.There is no chloroplast inside the animal cell. Chloroplast is a plant cell that produces photosynthesis from its food. The plants have a green color.The nucleus is located throughout the cell of the plant on the other edge of the peripheral cytoplasm, while the nucleus is in the animal's core.Plant cells store food of starch while animal cells store food of glucose.The mitochondria in the plant are fewer and also have tube cristae, whereas the animal cells have grown in various.For photosynthesis in green plants, the electron donor for the light-dependent reaction is?
Answers
For photosynthesis in green plants, the electron donor for the light dependent reaction is water.
What are the events during light dependent reaction?During photosynthesis, the light dependent reactions occur in the thylakoids. The electrons are provided by the breakdown of water.Within the thylakoid membrane, chlorophyll captures energy from the sun in the form of photons and breakdown the water molecules producing energy in the form of ATP and NADPH.Chlorophyll pigment is present in both Photosystem I (PS I) and Photosystem II (PS II) which are also known as light harvesting complexes.Light reactions begin with the excitation of electron in chlorophyll of PS II by sunlight. This excited electron leaves the chlorophyll and travels via electron transport chain.To fill the void created by the loss of an electron, PS II drives an electron by splitting of water molecule.Learn more about light-dependent reaction here:

22) describe the floating leaf disk assay test. what environmental factors affected the rising of the leaf discs?
Answers
The release of oxygen into the leaf's interior during photosynthesis alters the buoyancy of the leaf, causing the disks to rise.
In the floating leaf disk method, a vacuum is utilized to remove trapped air and to penetrate plant (leaf) disk samples with a solution containing bicarbonate ions, which act as a carbon source for photosynthesis. The release of oxygen into the leaf's interior during photosynthesis alters the buoyancy of the leaf, causing the disks to rise.
The rate at which the disks increase is an indirect indicator of the net rate of photosynthesis because cellular respiration, which is occurring concurrently and using oxygen, is also going place.

A mosquito which transmits malaria by injecting infected saliva into the blood of its victim is an example of a ______ vector, whereas a fly which transmits trachoma on its feet as it moves from one infected individual to the eye area of a non-infected individual is an example of a ______ vector.
Answers
A mosquito, which transmits malaria by injecting infected saliva into the blood of its victim, is an example of a biological vector. whereas a fly which transmits trachoma on its feet as it moves from one infected individual to the eye area of a non-infected individual is an example of a mechanical vector.
A biological vector is an organism that transmits a pathogen (such as a virus or bacteria) to a host. In the case of malaria, the mosquito serves as the biological vector as it harbors the Plasmodium parasite in its salivary glands, which it transmits to a human when it bites and feeds on blood. The parasite then infects the human host, leading to the development of malaria.
On the other hand, a fly that transmits trachoma on its feet as it moves from one infected individual to the eye area of a non-infected individual is an example of a mechanical vector. A mechanical vector is an organism that transmits a pathogen to a host without being infected by the pathogen itself.
In the case of trachoma, a bacterial infection that affects the eyes, the fly picks up the bacteria on its feet while feeding on the discharge from the eyes of an infected person. The bacteria can then be transmitted to the eye of a non-infected person when the fly lands on their eye, leading to the development of trachoma.
In summary, biological vectors transmit pathogens to hosts while being infected by the pathogen themselves, whereas mechanical vectors transmit pathogens without being infected by the pathogen themselves. Understanding the type of vector involved in the transmission of a pathogen is essential in developing effective control measures to prevent the spread of disease.

The chance of having a heterozygous fresh meat eater who buries its meat in a deep hole is one-half. This is due to the fact that the dominant gene for fresh meat (F) conceals.
the recessive allele for rotten meat (f), and the dominant allele for shallow burial (S) conceals the recessive allele for deep burial. From each parent, the kid will acquire one allele for each attribute. If the mother is homozygous dominant for both qualities, the dominant allele will always be passed on. Because he is heterozygous for both qualities, the male has a 50% probability of passing on each allele.

Question: Discuss at least two similarities and two differences between prokaryotes and protists, as well as some theory as to why these difference and similarities exist in paragraph form.
Answers
Prokaryotes and Protists have a number of similarities and differences, both in terms of their characteristics and their evolutionary history.
Similarities: Both prokaryotes and protists are unicellular organisms, which means that they are composed of only one cell. Both groups of organisms are also capable of reproducing asexually, meaning that they can create identical copies of themselves without the need for sexual reproduction.
Differences: One major difference between prokaryotes and protists is that prokaryotes lack a nucleus, while protists have a well-defined nucleus. This difference is due to the fact that prokaryotes are evolutionarily older than protists, and did not develop the nucleus as a separate organelle until much later in evolutionary history.
The reason for these similarities and differences can be traced back to the evolutionary history of these organisms. Prokaryotes are believed to be some of the earliest forms of life on Earth, and their simple structure reflects this early stage of evolution. Protists, on the other hand, evolved much later and developed many of the complex structures found in modern eukaryotic cellsLearn more about prokaryotes and protists-
