If a cell has 4 chromosomes at the beginning of meiosis, how many chromosomes will be in each cell at the end of meiosis?
Answer:2. Mitosis would produce identical daughter cells with the same number as the parent cell. Meiosis would product sex cells with one-half the amount of genetic material as the parent cells.
Explanation:
If a cell has 4 chromosomes at the beginning of meiosis then the daughter cell will have TWO chromosomes at the end of meiosis.
Meiosis is a type of reductional cell division by which a parental cell duplicates its genetic material (DNA) and then divides twice to produce four (4) daughter cells having half of the genetic material.These successive cell division cycles are known as Meiosis I and Meiosis II.Meiosis is a sexual mode of reproduction that produces gametes or geminal cells, which fuse during the process of fertilization to form a zygote.
In conclusion, if a cell has 4 chromosomes at the beginning of meiosis then the daughter cell will have TWO chromosomes at the end of meiosis.

Read the following paragraph from the section "Dreaming Of A World Deep Below."
The interior of our planet has long held a fascination for philosophers and storytellers. Some have speculated that another inhabited world lies beneath our own. In 1864, Jules Verne’s novel "Journey to the Center of the Earth" described the fictional adventures of explorers traveling under our planet’s surface. It was a best-seller. People wondered if the world Verne described below our own could be real.
Why does the author include this paragraph in the article?
Question 9 options:
to show how much scientific progress regarding the Earth's core was made during Lehmann's lifetime
to explain a number of popular theories concerning the composition of the Earth's core
to demonstrate how Lehmann's discovery confirmed what Jules Verne already knew about the Earth's core
to describe the attitudes Lehmann needed to overcome in order to introduce her work to the scientific community
Answer:
B
Explanation:
The interior planet has fascinated a lot of people so a lot of theories have been made about what's in there.
The reason author include this paragraph in the article is to explain a number of popular theories concerning the composition of the Earth's core. Thus, option B is correct.

how are the light reactions and the calvin cycle connected?
Answer:
The light reactions provide the Calvin cycle with oxygen for carbon fixation, and the Calvin cycle provides the light reactions with sugars to produce ATP. The light reactions provide ATP and NADPH to the carbon fixation step of the Calvin cycle, and the Calvin cycle provides water and electrons to the light reactions.
Explanation:
The energy that drives the Calvin cycle comes from ATP and NADPH produced by the light reactions, that is, the energy capture reactions in the first stage of photosynthesis.
The Calvin cycle is a process that results from photosynthesis made by plants, through which Carbon dioxide is absorbed and transformed into organic material or biomass.
In the light phase, light energy is stored in organic molecules that provide energy to carry out the process (ATP) and have the ability to donate electrons (reducing power) to another molecule such as NADPH.These molecules formed in the light reactions participate in the reactions that make up this cycle during which carbon dioxide (CO2) taken from the atmosphere is fixed, incorporating it into the body in the form of glucose thanks to the action of the enzyme RuBisCo.Therefore, we can conclude that the molecules constituted in the light reactions (ATP and NADPH) participate in the reduction of carbon dioxide (CO2) through the series of reactions of the Calvin Cycle.

An unknown material has a mass of 4.5 g and a volume of
6.75 cm3. What is the density
Answer:
0.67 cm³Explanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\[/tex]
From the question
mass = 4.5 g
volume = 6.75 cm³
We have
[tex]density = \frac{4.5}{6.75} \\ = 0.6666666...[/tex]

0.67 cm³Hope this helps you
in the reaction of aluminum metal and oxygen gas to make aluminum oxide, how many moles of aluminum will react with 0.80 grams o2?
Explanation:
When 6.38 moles of O2 and 9.15 moles of Al react, the ratio of aluminum to oxygen is 9.15/6.38 = 1.434. This shows that all of the oxygen is consumed before the aluminum and when the reaction ends the reactant aluminum is left. The number of moles of Al2O3 formed is approximately 4.25 moles.
