Answer:
The purpose of mitosis is to produce two genetically identical daughter cells from a single parent cell. During mitosis, the genetic material of the parent cell is equally divided into the two daughter cells. Each daughter cell receives a complete copy of the genetic material, which consists of a specific number of chromosomes. The number of chromosomes in a cell is determined by the organism it belongs to. For example, human cells have 46 chromosomes, while fruit fly cells have only 4 chromosomes.A fixed pulley is classified as a simple machine because it changes which of the following aspects of the input force

Rocks change during metamorphism because the minerals need to be stable under the new temperature and pressure conditions. While metamorphic rocks are forming, the extreme heat changes the size and shape of the mineral grains in the rock.
Which statement describes the effect of the conditions described in this passage?
A. The need for stability may cause the structure of minerals to rearrange and form
new minerals
B. Great pressure from tectonic plate collisions can change rock into metamorphic
rock
C. The high temperatures of the magma can change nearby rock into metamorphic
rock
D. Metamorphic rocks are classified according to the arrangement of the grains in
their makeup

what is wrong with this statement?: sperm and egg cells go through mitosis and divide a total of 1 time
Approximately 20% of the world’s adult population are able to digest milk sugar (lactose).They are “lactose tolerant.” This trait is known to be controlled by a single dominant gene. Therefore, we would expect that
no lactose tolerant individuals have two biological parents that are lactose INtolerant.
all lactose tolerant individuals to be heterozygous for the gene.
60% of lactose INtolerant individuals would be heterozygous.
all children of lactose tolerant parents will also be lactose tolerant.
Answer:
No lactose individuals have two biological parents that are lactose intolerant
Explanation:
In this case lactose intolerance would be coded for a recessive gene (r). if both parents are lactose intolerant the would both be the genotype (rr) . For individual to be lactose intolerant atleast one parent most be lactose tolerant posesing the dominant (R) gene. Which both parents in this example lack.

The Go' for the reaction Citrate Isocitrate is +6.64 kJmol-1 . The Go' for the reaction Isocitrate α-Ketoglutarate is -267 kJmol-1 . Calculate the Go' for the conversion of citrate to α-ketoglutarate?
Answer:
ΔG°' for the conversion of citrate to α-ketoglutarate = - 273.64 kJmol-1
Explanation:
ΔG°' for Citrate is +6.64 kJmol-1
ΔG°' for Isocitrate is -267 kJmol-1
ΔG°' for the conversion of citrate to α-ketoglutarate = ΔG°' for product - ΔG°' for reactant
ΔG°' for the conversion of citrate to α-ketoglutarate = -267 kJmol-1 - (+6.64 kJmol-1)
ΔG°' for the conversion of citrate to α-ketoglutarate = - 273.64 kJmol-1

Which description explains why there are two high and two low tides in a day? (4 points)
Earth moves closer to the sun and moon twice a day.
Earth revolves around the tidal bulges created by gravitational forces.
Earth rotates in and out of a tidal bulge twice a day.
The moon's gravity increases over the oceans and decreases over the land.
Answer:
Earth rotates in and out of a tidal bulge twice a day.
Earth always has two surrounding gravitational forces, one proceeding from the moon and one from the sun.
The sun's pull, despite the fact our sun is further then the moon, is stronger and creates the high tide, and the moon the low tide. But as we know our earth moves, now exposing the other side to the sun which in turn leaves the other side of earth with the high tides and the other with the low tides. Tides never move, what moves is earth.

Explanation:
Hope that helps
Answer:
Magma made of Water vapor, carbon dioxide, and sulfur.
Explanation:
Like solid rock, Magma is a mixture of minerals. The high temperatures and pressure under Earth's crust keep magma in its fluid state.

9. why Energy released by aerobic and anaerobic respiration in animal are not same.
Answer: Anaerobic respiration produces a relatively lesser amount of energy as compared to aerobic respiration, as glucose is not completely broken down in the absence of oxygen. In animal cells anaerobic respiration often occurs during exercise. The glucose does not get fully broken down in this process, so it does not release its full potential energy. Instead of carbon dioxide and water it breaks down to form lactic acid and a small amount of energy.

Tina is studying chipmunks in a field of 900 square meters. In 2020, she counts 194 chipmunks. In 2021, she counts 231 chipmunks. What is the population density of chipmunks in 2021?
Answer:the population density of chipmunks in 2021=256,666.667 per square kilometres
Explanation:
Population density is defined as the number of population per unit area of land
which can be expressed as
Population density =number of population/ land area
Since land area is usually given in square kilometres or square miles we convert 900 square meters to square kilometres
1 square kilometres =1000000 square meters
900 square meters=900/1000000=0.0009 square kilometres
Therefore, the population density of chipmunks in 2021= 231/0.0009 square kilometres =256,666.667 per square kilometres

Describe the relationship between density and temperature
Answer:Density is directly proportional to pressure and indirectly proportional to temperature. As pressure increases, with temperature constant, density increases. Conversely when temperature increases, with pressure constant, density decreases.

Answer:
the temperature of planets closes to the sun is hotter than planets far away
how does energy cause global warming
Answer:
Global warming is caused primarily from putting too much carbon into the atmosphere when coal gas and oil are burned to generate electricity or to run our cars. These gases spread around the planet very fast, keeping the solar heat that would otherwise be radiated out into space!
