DNA is the genetic information, which must be copied for the next generation of cells.
• The genetic information is stored in DNA and DNA possesses the tendency to replicate and get inherited.
• The genetic information is passed from one generation to the other in the form of DNA.
• The genetic information is passed from parent to the offspring via se-xual or ase-xual mode, and in both the cases it is transferred in the form of DNA.
• The genetic information contained within the DNA of an organism comprises the instructions for all the proteins the organism will ever produce.
Thus, the correct answer is option B, that is, DNA.

Which of the following best describes the theory of natural selection?
The genetic makeup of a population gradually changes from one generation to the next due to spontaneous mutation.
Living organisms change over time due to the flow of energy, which is a key factor in determining what kinds of organisms can live in a particular community.
There is variation among the members of a species. Some of this variation is genetically determined and so can be passed on to future generations on chromosomes inherited from the parents.
Some individuals have genes that increase their chances for survival and reproduction. These individuals are more likely to reproduce and pass on their genes, causing their genes to become more common in the next generation.
There is a struggle for existence among the members of a population. Cooperation allows several species to exist in one area, while competition tends to eliminate species.
Answers
Answer:
Some individuals have genes that increase their chances for survival and reproduction. These individuals are more likely to reproduce and pass on their genes, causing their genes to become more common in the next generation.
Explanation:
The basic idea of natural selection is that environmental conditions determine how well the characteristics of organisms contribute to the survival and reproduction of the organism; organisms that do not have these traits may die before reproduction or be less fertile. As long as environmental conditions remain the same or close enough for these traits to remain adaptive, these traits will become more common in populations. The loss of an ecological niche of a species or overcrowding as a result of an increase in abundance can significantly alter the adaptive characteristics required for survival. In this case, and also in any environment where survival is determined more by ecology than secondary sex characteristics, ecological choice takes place.

What condition is necessary for a genetic change that occurs in one individual to be spread to other individuals?
A. a common gene pool
B. a common phenotype
C. a similar habitat
D. a similar niche
Answers
Answer:
a
Explanation:
A common gene pool is a need for a genetic alteration that occurs in one person to be passed on to other people. The aggregate genetic makeup of a species or group is referred to as its gene pool.
What is the scenario with the genetic change in the population ?The whole of the population's alleles, or genetic variations, that may be transmitted from parents to children through reproduction. If two people share a gene pool, a genetic alteration experienced by one person can transmit to the other person.
This is so that the person who had the genetic change's progeny won't inherit the altered gene. It is not essential for a genetic modification to be passed on to other people for them to have a common phenotype. The traits or outward appearance of a phenotype of an organism, which is based on its genotype (the organism's genetic make-up). Although an organism's genotype can affect its phenotype, there isn't always a clear connection between the two.
Consequently, a shared phenotype is not a need for a genetic mutation to be passed on to other people. Similar environment and niche requirements are not essential for a genetic mutation to propagate to other people, either.
A niche is the function that an organism plays in its environment, whereas a habitat is the actual setting in which an organism lives. Although changes in habitat or niche can have an impact on an organism's genetic composition, they are not prerequisites for a genetic mutation to propagate to other people.

One result of meiosis is the formation of gametes
A. True
B. False
Answers
Answer:
T
Explanation:
It is true that the result of meiosis is the formation of gametes. Therefore, option A is correct.
What is meiosis?a unique method of cell division in which the amount of DNA received by each daughter cell is halved compared to the parent cell. In mammals, meiosis takes place during the development of egg and sperm cells.
Since meiosis involves two rounds of cell division, a beginning cell can generate four gametes (eggs or sperm). Cells move through prophase, metaphase, anaphase, and telophase with each round of division.
Chromosome reduction, or meiosis, is the process that enables the generation of haploid germ cells required for sexual reproduction. Meiosis also plays a crucial function in promoting genetic variety and making it easier for recombination to correct genetic flaws. Hence, option A is correct.

Diffusion of nutrients across a cell membrane can be called a form of Multiple Choice bulk transport. exocytosis. osmosis. active transport. passive transport.
Answers
Answer:
passive transport
Explanation:
Diffusion is one of the ways molecules/substances move or is transported. It is the process whereby substances move from a region of higher concentration to a region of lower concentration until there is an even distribution. Movement via diffusion occurs down a concentration gradient i.e high to low.
Since diffusion occurs down a concentration gradient, which is difference in concentration of a substance, it requires no energy in form of ATP to occur. This kind of transport which requires no energy input is called PASSIVE TRANSPORT, in contrast to active transport which requires.
• Distinguish between cytoplasm and cytosol
Answers
Answer:
Cytoplasm Meaning
Cytoplasm is the component of the cell surrounded by the cell membrane. All the cell organelles are present in the cytoplasm. It helps in large cellular activities such as glycolysis or nuclear division. The inner concentrated region of the cytoplasm is called the endoplasm, whereas, the outer region of the cytoplasm is called ectoplasm.
Cytosol Meaning
Cytosol is known as the matrix of the cytoplasm. It surrounds the cell organelles in eukaryotes. In prokaryotes, all the metabolic reactions occur here.
Thus, we can infer that while cytosol is the fluid contained in the cell cytoplasm, cytoplasm is the entire content within the cell membrane.

Answers
Answer:
substitution; deletion; insertion
Explanation:
Mutations are genetic changes generally associated with deleterious effects. However, mutations may not have an effect on the phenotype of the organism and even, eventually, they are beneficial. For example, a missense substitution occurs when a nucleotide is replaced by another that changes the encoded amino acid, which may have deleterious or beneficial effects (depending on the new protein and its effects on the fitness of the individual in a particular environment), while a silent substitution does not modify the encoded amino acid and thereby it has no effect on the phenotype. On the other hand, a frameshift mutation is a mutation that involves the insertion or deletion of a nucleotide base, thereby irreversibly altering the Open Reading Frame (ORF) of the protein.

that tropical rainforests would be large net producers of oxygen, and yet surprisingly, they are not! With
your knowledge of photosynthesis and cellular respiration, can you explain why this might be true?
Think about what happens when a leaf drops or fruit from a tree is eaten.
Answers
Answer:
Tropical rainforests such as the Amazon have been said to produce so much of Earth's oxygen when in fact this is not necessarily true.
Plants do indeed use Carbon dioxide during photosynthesis and the end product is Oxygen. The amount of oxygen produced however is more or less equivalent to the amount of Carbon dioxide taken in as atoms cannot be multiplied. With Carbon dioxide comprising only 0.04% of air, the oxygen produced is not as much as one would think.
After these trees produce Oxygen, they will also use it during respiration to produce energy which means that they would be sucking in most of the oxygen that they created. This would therefore reduce the net oxygen coming from these trees.
Another thing is that when plant life dies and is decomposed, the carbon dioxide that it stored from will be released back into the atmosphere. Leaves falling and fruits eaten will have this effect as well and since this happens a lot in tropical rainforests, their net oxygen production decreases.

Use Sammi's model as an example to explain why cells are the building blocks for human bodies?
Answers
Answer and Explanation:
The cell is a basic functional and structural unit of life. All living organisms are made up of cells. The human body contains approximately 100 trillion cells in our blood, skin, nerves, muscles, bones, and brain. Humans have 200 diverse forms of cells that come in different sizes and shapes. Each cell performs a specific function in the human body. There are four main types of cells: nerve cells, muscle cells, epithelial cells, and connective tissue cells. Nerve cells are specific for communication. These cells send signals from the brain to glands and muscles that control functions. Nerve cells receive sensory information is from the skin, the ears, and the eyes and send this information to the brain. Epithelial cells cover the interior of hollow body organs such as digestive organs or blood vessels. Muscle cells are specific for contraction. The body cannot move without muscles. Connective tissue cells protect against foreign invaders and also provide strength to the body.
Answer:
Cells are the building blocks for human bodies since cells have diverse sections and each performs specific duties. A cell refers to the simplest, basic unit of life. The circulatory system's various components are depicted on the model using everyday objects. From the model, it can be seen that some of the parts that are represented include the heart, blood vessels, capillaries, and digestive tract. This illustrates that for blood to be pumped into the body, different organs have specific roles to play just like the cells have different functions to play in the human body.
