The purpose of meiosis is to shuffle genetic information and cut the cellular chromosome number in half, from 46 chromosomes to 23 chromosomes. ... In humans, the reduction division results in two sperm cells each with 23 chromosomes or an egg cell with 23 chromosomes and one discarded polar body.

What made the 1918 flu virus so deadly?
Explanation:
The virus killed people directly by causing massive hemorrhages and edema in the lungs. Modern analysis has shown the virus to be particularly deadly because it triggers a cytokine storm (overreaction of the body's immune system

When spindle fibers do not correctly separate the chromosomes during anaphase we get a condition called _________?
A. Duplication
B. Nondisjunction
C. Translocation

Why is the reduction in chromosomes number important in meiosis?
Explanation:
Because meiosis creates cells that are destined to become gametes (or reproductive cells), this reduction in chromosome number is critical — without it, the union of two gametes during fertilization would result in offspring with twice the normal number of chromosomes.
How does the release of carbon dioxide by microorganisms benefit plant life?
a.
It reduces the acidity of water in soil, which increases water absorption and provides plants with necessary water.
b.
It increases the acidity of water in soil leading to the breakdown of rocks in soil. This releases nutrients which can be used by plants.
c.
It decreases the acidity of water in soil leading to the breakdown of rocks in soil. This releases nutrients which an be used by plants.
d.
It increases the acidity of water in soil, which decreases water absorption providing plant life with firmer soil for root growth.
Answer:
b.
It increases the acidity of water in soil leading to the breakdown of rocks in soil. This releases nutrients which can be used by plants.
Explanation:
When microorganisms release carbon dioxide into the soil, the acidity of water surrounding soil particles is increased. This increase in acidity allows for rock present in soil to be broken down, releasing minerals into the soil. These minerals are then available for use by plant life.

Explanation:
Scientists recently discovered a species of bacteria that’s capable of photosynthesis, but it’s anaerobic and doesn’t produce or use oxygen for respiration. Which process will be absent in this organism?
A.
Calvin cycle
B.
electron transport system
C.
glycolysis
D.
Krebs cycle
Explanation:
The answer is D. Krebs cycle. the Krebs cycle only occurs when oxygen is present, and so it would seem to be the same for the electron transport system... although, in anaerobic bacteria, it is still used as a respiratory electron transport chain called physolmere.
Answer:
Krebs cycle
Explanation:
DNA is found in the nucleus of eukaryotic cells and the ribosomes, the location where proteins are made, are found out in the cytoplasm of the cell as show below. Explain why this is a problem and how the cell solves this problem.
Answer:
See the answer below
Explanation:
The DNA of eukaryotic organisms being present in the nucleus while the protein-synthesizing organelle, the ribosome being present in the cytoplasm poses a spatial problem. It means that transcribed DNAs (messenger RNA) in the nucleus would have to somehow be transported to the ribosome in order for the cell to successfully synthesize proteins.
The problem of transporting the messenger RNA is solved by two features of the cell:
The presence of pores in the nuclear envelopThe presence of transport proteins in the nucleusThe mRNA binds to the transport proteins to form mRNA-protein complexes and is transported through the nuclear pores, often with the assistance of ATP.
During translation, a ribosome binds to
O a protein
O mRNA
O DNA
O peptide bond
Answer:
I think it mRNA will be the answer

how does an increase in volume affect the gas pressure in a balloon
Answer:
Boyle's Law explains the relationship between volume and pressure. According to Boyle's Law, the volume of a fixed amount of gas decreases as its pressure increases. If the volume increases, its pressure decreases.

.A jogger with a mass of 81.6 kg is moving at 2.2 m/s. What is the jogger's
kinetic energy
Answer:
89.6Joules
Explanation:
Kinetic energy is 1/2MV^2
Where m is Mass and v is velocity.
M=81.6 v=2.2m/s
K.E= 1/2 × 81.6 × 2.2
= 81.6 ×1.1
K.E=89.6 Joules
How much energy consumed is lost to waste?
Answer: To begin with, it shows that more than half (58%) of the total energy produced in the US is wasted due to inefficiencies, such as waste heat from power plants, vehicles, and light bulbs. In other words, the US has an energy efficiency of 42%.

circle with center at (-3, 7) and radius 8
Explanation:
Centre of the circle ( h,k)=(-3,7)
radius of the circle (r)=8
Equation of the circle is,
(x-h)^2+(y-k)^2=r^2
or,(x+3)^2+(y-7)=8^2
or,x^2+6x+9+y^2-2y+49=64
or,x^2+y^2+6x-2y+58-64=0
or,x^2+y^2+6x-2y-6=0 is the required equation of the circle

Based on the the table of rock characteristics and your knowledge of the rock cycle, in which type of
rock (igneous, metamorphic, or sedimentary) would you expect to find bubbles or a smooth, glassy
surface? Why?
HELPPPP ASAP
Answer:
The answer would be igneous. But there are two types of igneous rocks. One is Intrusive, or Plutonic, rocks, and the other is Extrusive. Intrusive rocks crystallize from magma beneath the earth's surface. Extrusive or volcanic rocks crystallize from lava at the earth's surface. Either way, Igneous would have a bubbly, or a smooth, glassy surface.

Atoms are the most basic unit of matter. Two or more atoms from the same or different elements can combine to form molecules.
Cells are the most basic unit of life. Cells are made up of many different types of molecules. Which of the following accurately shows higher levels of organization within organisms, from least complex to most complex?
A. cells → organs → organ systems → tissues → organism
B. cells → tissues → organs → organ systems → organism
C. cells → organ systems → organs → tissues → organism
D. cells → organs → tissues → organ systems → organism
Answer:
B
Explanation:
Because cells make tissues which then combine to make organs which then further combine to form system
Which makes organisms like me and you
Answer: B
(An atom is the smallest unit of matter that retains all of the chemical properties of an element. Atoms combine to form molecules, which then interact to form solids, gases, or liquids. For example, water is composed of hydrogen and oxygen atoms that have combined to form water molecules.)
