At the beginning of mitosis, a mosquito cell has six double-stranded chromosomes. This cell will have split into two daughter cells with six chromosomes each at the end of mitosis. Consequently, 6 chromosomes will be provided to each daughter cell (single-stranded).
What is mitosis?One cell divides into two genetically identical daughter cells during the cell duplication process known as mitosis. The cell's chromosomes are duplicated throughout the process of mitosis and then divided equally between the two daughter cells' two new nuclei.
Every chromosome acquires identical copies of the parent cell's DNA thanks to anaphase. At their centromere, the sister chromatids divide in half to form distinct, identical chromosomes.

Environmental factors can influence natural selection because they can increase or decrease and what can they increase or decrease in
Environmental factors can influence natural selection because they can increase or decrease and what can they increase or decrease in the amount of genetic variation in a population.
What is natural selection?Populations of living things adapt and change through a process called natural selection. A population's members are naturally varied, which means that they are all distinctive in some ways. Because of this variety, some people have characteristics that suit their surroundings more than others.
Four requirements must be met for natural selection to take place: reproduction, inheritance, variety in physical traits, and variation in the number of children produced by each person.
Reproduction:
A population must procreate to produce a new generation in order for natural selection to affect it. Over many generations, people who have the characteristics that are most compatible with their environment tend to breed more than people who don't.
Heredity:
Since the genes of the parents combine to form the DNA of their offspring, heredity and reproduction go hand in hand. Natural selection must operate if parents with favourable qualities pass those traits on to their kids.
Variation in Characteristics:
Only when individuals within a community differ in their personal features can natural selection take place. For instance, different people must have varied colors in order to research natural selection on color within a population. There wouldn't be any traits for nature to "select" over others in the absence of variety in traits.
Fitness Variation:
Compared to its popular notion, fitness has a more technical meaning. Fitness in the context of evolution refers to an organism's capacity for maximum survival and reproduction. Natural selection cannot take place in a population unless its individuals have varying levels of fitness. Some people must have characteristics that make it easier for them to survive and procreate more frequently than others. Otherwise, natural selection cannot act to increase the number of people with advantageous features and decrease the number of people with undesirable qualities.

What engineer Nikolaus August Otto developed?Engineer Nikolaus August Otto developed the first four-stroke internal combustion engine and established the Otto cycle, a well-known theoretical cycle that governs the operation of explosive engines.
Otto's engine outperformed the steam engine in use at the time in a number of ways. One of them is their light weight, as steam engines need large water reservoirs and fuel to burn in order to heat the water, which in this case would be charcoal or firewood. In addition to being light, the internal combustion engine consumed little fuel, even benzene. Another factor was Otto cycle internal combustion engines' power, which also outperformed steam engines in terms of size ratio.
These benefits put pressure on the automotive sector to build vehicles with this kind of technology. Blacksmiths were compelled to learn new skills in order to use this new technology.
In addition to being light, the internal combustion engine consumed little fuel, even benzene. Another reason was Otto cycle internal combustion engines' power, which also outperformed steam engines in terms of size ratio.

A. the surrounding air
B. a burner at the same temperature
C. a pan heated to 100°C
D. hotter water inside a pan
Answer:
Option C, a pan heated to 100°C
Explanation:
The pan on the burner will be in direct contact of the heat released by burner and hence the pan will receive the direct flow of heat from the burner.
However, the water is the pan will be heated by the heat transferred from the pan to the water in it. Water will not receive heat directly from the burner.

2.what is translocation ??,give the chemical equation for translocation
plss help will mark brainlest..
Transpiration is a water balance process mediated by stomata opening. Translocation is the transport process of photosynthetic substances from leaves to other tissues.
What is transpiration?Transpiration is a water balance process.
Through stomata opening and closure (which depends on how hydrated the plant is) water vapor is expelled from the leaves.
If the plant is dehydrated, stomata close. If it is not dehydrated, it opens.By limiting water exit, stomata allow more water molecules to be available for light reaction processes when the plant is dehydrated.
The equation to calculate transpiration is as follows,
E = Gv (Cvs - Cva)
Where,
E is transpiration.Gv is the total vapor water conductance.Cvs is the water concentration inside the leave.Cva is the air water concentration.What is translocation?Translocation is a fast and dynamic process through which photosynthetic products are transported from the leaves to other tissues of the plant to be used or stored.
This transport is done by the phloem cells through active transport or osmosis (depending on the substance).
The translocation of elements from the leaves to the roots is fast.
In conclusion,
The chemical equation for transpiration is E = Gv (Cvs - Cva). Translocation is the movement of photosynthetic products from leaves to other plant tissues.You can learn more about translocation and transpiration at

Sexual reproduction increases the genetic variation of a species because:
Answer:
Sexual reproduction increases the genetic variation of a species because it involves combining of genetic materials of two parents/individuals to form an offspring.
Explanation:
Sexual reproduction is a type of reproduction that involves formation of an offspring by combination of male and female gametes. Each gamete carries a haploid set of chromosomes. When gametes from both the parents combine, a zygote is formed which has a diploid set of chromosomes. So, sexual reproduction involves combination of genetic materials of two different individuals, hence, it leads to genetic variation.

Saturn is close to Polaris during some years
true or false
Saturn is not close to polaris
Polaris disappears into the horizon as seen from the equator, and is not visible from the south of the equator. Finding Polaris in the Northern Hemisphere indicates that you are aware of the direction north.
What is the importance of Polaris?Directly above Earth's North Pole is the Pole Star, or Polaris. Due to its location over the North Pole, the pole star is aligned with the earth's axis. As the sole star that is stationary, it is crucial for orientation.
It makes a fairly small circle over the course of a day since it is so close to the celestial equator. As a result, Polaris is a trustworthy indicator of north, since it always remains in nearly the same location in the sky.
Therefore, it is false that Saturn is close to Polaris during some years.
