Explain how genetic mutations may result in genetic and physical variations differences) within a population.
Answer:
The correct answer is - Mutations produce different versions of genes.
Explanation:
Mutations are the changes in the gene or DNA of an organism that leads to the production of different version of genes and proteins. Mutations result in genetic variation or physical variation within the population as it introduces new alleles in the populations.
Mutations introduce or remove various versions of genes called alleles within a population and increases genetic variation. These changes in the genes are the source for new genetic variation. Genetic or physical variation does not occur without mutations.
True or false
An allele is the name given to the position of a gene on a chromosome.

Explanation:
Tropical rainforests are found closer to the equator where it is warm. Temperate rainforests are found near the cooler coastal areas further north or south of the equator. The tropical rainforest is a hot, moist biome where it rains all year long.
What can scientists assume about individuals with similar anatomy?
I
Answer:
Scientists compare the anatomy, embryos, and DNA of living things to understand how they evolved.
Explanation:
Evidence for evolution is provided by homologous structures. These are structures shared by related organisms that were inherited from a common ancestor. Other evidence for evolution is provided by analogous structures
Scientists use anatomy for the study of the evolution of DNA other organs and how they are modified.
Similar anatomy means homologous structure as they provide the information for evolved structure. They provide evolutionary evidence.
What is an analogous structure?
Organisms that have developed alongside special paths may also have analogous systems—that is, anatomical functions which can be superficially just like one another (e.g., the wings of birds and insects). Although such systems serve comparable functions, they have got pretty special evolutionary origins and developmental patterns.
Thus it is clear that scientists assume individuals with similar anatomy for evidence of evolution.

When the concentration of a solution is higher inside a cell than it is outside of the cell, is the solution inside hypertonic,isotonic, or hypotonic?
Answer:
Hypertonic solution
Explanation:
Hypertonic solution refer to the solution of a cell if the solute concentration is higher inside than outside and it cannot cross the membrane. In Hypertonic solution, Water crosses the cell membrane in both directions which result in more b water leaving the cell than entering it. Therefore, a cell place in this solution will shrink due to exosmosis.
What are tiny organisms that float near the surface of freshwater and marine environments?
Answer:
These tiny creatures are referred to as "plankton."
Plankton includes plants and animals that float along at the mercy of the sea's tides and currents. Their name comes from the Greek meaning "drifter" or "wanderer."
6. explain the relationship between temperature and pressure. why do you think this occurs?
Answer:
The pressure of a given amount of gas is directly proportional to the temperature at a given amount of volume. When the temperature of a system goes up, the pressure also goes up, and vice versa.
Explanation:
This occurs because of the pressure temperature law. (or also known as the Gay-Lussac's law)

If a population grows by 3 percent each year, the growth of the population is
A. exponential
B. linear
c. cubic
D. logarithmic
Answer:
A. (exponential) population
If a population grows by 3 percent each year, the growth of the population is exponential. Hence, option A is correct.
What is exponential growth?A function called exponential growth depicts an expansion within a population that happens at the same pace across time. If a population doubles or triples in size, you can assume that the data grows exponentially. Exponential decay is the inverse of exponential growth, in which data contracts rather than expands.
Bacteria are one of the best illustrations of exponential growth. Prokaryotic fission is a method of bacterial reproduction that takes around an hour. The population size of 100 bacteria would increase exponentially if we measured it every hour in a certain environment.
The population growth is exponential. Hence, option A is correct.

What is the difference in the number of chromosomes found in each cell produced in meiosis compared with mitosis?
a-Cells produced during meiosis have half the number of chromosomes as cells produced in mitosis
b- Cells produced during mitosis have half the number of chromosomes as cells produced in meiosis.
c-Cells produced during meiosis have the same number of chromosomes as cells produced in mitosis.
The cells in our bodies contain 23 pairs of chromosomes - giving us 46 chromosomes in total. Sperm cells and egg cells contain 23 single chromosomes, half the normal number, and are made by a special form of cell division called meiosis. ... Meiosis II divides each chromosome into two copies (much like mitosis).
cual es la diferencia netre los cloroplastos y la cianobacteria si ambos son bacterias fotosinteticas???
Answer:
Encontré esto en un texto de microbiología, tal vez sea útil.
Explanation:
"Las cianobacterias y los cloroplastos de las plantas tienen ambos fotosistemas, mientras que las bacterias fotosintéticas anoxigénicas sólo utilizan uno de los fotosistemas. Ambos fotosistemas son excitados simultáneamente por la energía luminosa. Si la célula requiere tanto ATP como NADPH para la biosíntesis, entonces llevará a cabo una fotofosforilación no cíclica".

How can pollution reduce the rate of photosynthesis? Research work (60-90 words) unnecessarily,useless answers will be reported
[tex] \huge\mathcal\green{answer}[/tex]
Air pollution has become an extremely serious problem. Air pollutants affect both plants and animals. Under polluted conditions, plants develop different physiological, morphological and anatomical changes. Pollutants cause damage to cuticular waxes by which then they enter the leaves through stomata. This further leads to injury to plants which can be either acute or chronic. Changes in stomata due to air pollutants which seem to be small can be of great consequence with respect to survival of the plant during stress. These effects can further lead to disturbing the water balance of leaf or whole plant. Respiration also gets affected because of the exposure of plants to air pollutants. The present paper deals with the effect of air pollutants on stomata as well as on respiration leading to affect gaseous exchange.
