Mitosis, followed by cytokinesis, results in the formation of two genetically identical daughter cells. This is because:______
a. after replication, the material is compared and corrected to be identical. the chromosomes pair up (synapse) in prophase as a counting mechanism.
b. all the genetic material is duplicated then segregated equally to the daughter cells.
c. daughter cells are initially haploid, but they duplicate their chromosomes to become diploid again.
d. the number of chromosomes needs to be reduced before cytokinesis.
Answer:
b.
Explanation:
The correct answer would be that all the genetic material is duplicated then segregated equally to the daughter cells.
Mitosis has to do with the division of vegetative or non-reproductive cells in the body of organisms. At the interphase stage of each cell cycle prior to mitosis, the genetic materials of the cell are doubled or duplicated.
These genetic materials are then distributed equally to the two daughter cells that are produced at the end of the mitotic process. It thus means that the resulting daughter cells are genetically identical in all ramifications.
The correct option is, therefore b.
Mitosis, followed by cytokinesis, results in the formation of two genetically identical daughter cells because: B. all the genetic material is duplicated then segregated equally to the daughter cells.
Mitosis refers to a type of cell division (duplication) through which a single (1) parent cell produces two (2) genetically identical daughter cells.
In a mitotic division, the two (2) genetically identical daughter cells produced by one (1) parent cell generally have an equal number of chromosomes as their parent cell, this process is referred to as duplication division.
In this context, if a cell divides by mitosis followed by cytokinesis, this would result in the formation of two genetically identical daughter cells because all the genetic material is duplicated and then segregated equally to the daughter cells.

What provides structure for plants
1. Carbonhyrdrates
2. Lipids
3. Nucleic acids
4. Proteins
Answer:
The correct answer is : 1. carbohydrate.
Explanation:
Cellulose is a major substance present in cell walls of the plants which provides support to the structure of plants. As it is most abundant bio polymer in nature are made up of monomers of glucose molecule joined together by bonds in between specific carbon atoms.
The rigidity of the plant is come from this carbohydrate, cellulose. Lipids, proteins are also component of the plant cell and plays various role in the cell for instance lipid acts as barrier and present in plasma membrane of the plant cell and provide insulation too.
Thus, the correct answer is : 1. carbohydrate.
who created the earth
Explanation:
Hey, there!
It's not obvious that who created the Earth.
Noone can say the answer of who created Earth because Earth wasn't created by any human or any specific creatures.. So, let me give some information about creation of Earth. Many hypothesis has been given by our great astronomers and philosophers. Here, i'm gonna describe some:
Old planetesimal hypothesis: According to this hypothesis there was a huge gaseous mass and comet collided together as a result, a very large amount of matter was thrown out of the sun, which later on cooled and planets are formed.Nebular hypothesis: According to this hypothesis the sun, the earth and other planets were formed by a large whirling cloud of hot gases and dust. When the cloud cooled and grew smaller, it began to spin faster. As the surface of the cloud cooled by radiation, a ring a matter was formed at the equatorial region of it.New plantesimal hypothesis: According to this hypothesis, the gaseous mass didn't collied with comet but they came closer to one another and due to gravity of comet, great tidal rose on gaseous mass. The materials rise up as a large spiral arms. Then the spiral arms were cooled down and broke away from the main mass. Then they were considered to be planets and main mass as the sun. It is modern of old plantesimal hypothesis. Tidal hypothesis: According to this hypothesis, it was also supposed that a comet passed through and had exerted a tidal pull upon a mass. The outer part of the filament escaped into space, inner part came back into the gaseous mass and middle part formed different sizes, which were planets and remaining were sun.Dust-cloud hypothesis: This hypothesis is different tgan above. It says tgat all planets were formed by large cloud of dust and gases. The light of stars pushed the atoms of gases and dust to form a large particals. These particals were attracted to eachother by gravity and began to crowd together. Eventually, a huge ball of materials formed the sun and the solar enegry was produced by nuclear reaction. Other particals remain near the sun and started revolving around it. The huge whirlpools originated in the rotating clouds which formed the smaller gaseous glodsand dust to form planets.This is how the earth was originated or created according to different hypothesis. so, there is no any single people or things that created the earth.

Compare and contrast the functions of each of the following types of flasks: filter, Erlenmeyer, volumetric. (Site 1)
Answer:
Explanation:
1. A filter flask is made up of heavy, transparent glass and suction pump at one side. This kind of flask is used for filtering or distillation of substances and is not the best option for measuring as it is not accurate.
2. An Erlenmeyer flask is a conical flask that is best suitable for titration and for storing chemicals.
3. Volumetric flasks are the best kinds for preparing accurate volumes. They are used for making accurate measurements of solutions.
Answer:
See Below
Explanation:
The filter flask is an Erlenmeyer flask with a side-arm adapter. This arm allows a scientist to remove unwanted impurities from solids, liquids, or gases in a chemistry experiment. Ultimately, it allows the fluid, or filtrate, to pass through, but stops the solid particles in the process. The Erlenmeyer flask is designed with a flat bottom so it can be used to either boil a liquid or allow a liquid to form condensation. This flask allows a laboratory technician to stir or heat a solution without losing any liquid by placing a stopper in the neck. Lastly, volumetric flasks are used for creating solutions. With their long, narrow neck and flat-bottom, these flasks have a number of advantages and disadvantages. Their specific set of measurements provides a scientist great accuracy. A scientist can use this flask to create solutions, when a solute is mixed with a solvent. It can also be used for dilutions, when a liquid is made thinner by adding water or another solvent. However, because the neck of the flask is so narrow, it can be difficult to pour the measured liquid out of the flask if the scientist over-poured the measurement.

Answer:
depends on F1 and F2
Explanation
Dominant traits
Dominant trait is a characteristic that clearly expresses, overwhelms other traits of the same type in a heterozygous genetic combination; is shown mainly in the F1 generation.
Diving traits
Recessive trait is a trait that cannot be expressed because it is overwhelmed by other traits of the same type (with a pair of symmetrical alleles) in a heterozygous genetic combination; recessive has not been shown in F1, but only occurs in F2 generation.

Why don't the spontaneous deleterious mutations that occur in an individual
e.coli cause downward drops in fitness in this population? see section 23.6 ( page 475) ?
Answer:
Please see below
Explanation:
The reason behind this is the phenomenon of natural selection. The deleterious mutations do not provide a survival advantage so they are selected against, which results in these type of mutations to not be passed on - rather, they eventually get eliminated from the population.
