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.

Write a poem about symbiotic relationships. It must include Commensalism Mutualism, Parasitism, Competition, and Predation.
Answer:
Explanation about Commensalism Mutualism, Parasitism, Competition, and Predation are given below.
Explanation:
There are various symbiotic relationship formed between the organisms present in the environment. These relationships are Commensalism Mutualism, Parasitism, Competition, and Predation. In Commensalism relationship, one organisms gets benefits while the other neither get benefit nor harm. In mutualism, both organisms gets benefits from one another. In Parasitism, one organism get benefits and the other get harmed. In Competition, both organisms cause harm to one another and both are damaged through their actions and in Predation, one organism is benefited by killing the other organism to feed itself.
Some plants have a waxy covering on their leaves. How does the waxy covering help
the plant to survive?
O It allows the plant leaves to grow wider and collect more sunlight.
It discourages predators from eating the plant.
It helps the plant reproduce faster in colder environments.
O It helps the plant keep its moisture in hot weather conditions.
Answer:
It helps the plant retain water.
The waxy covering on plant leaves, young stems, and fruit is called the "cuticle". It is composed of cutin, a wax-like material produced by the plant that is chemically a hydroxy fatty acid. The purpose of this covering is to help the plant retain water.
Answer:
D. It helps the plant keep its moisture in hot weather conditions.

The sides or backbone of DNA is made up of what two molecules? (green in the diagram below)
Multiple choice answers
-Sugar-Nitrogen Base
-Sugar-Phosphate
-Phosphate-Nitrogen Base
-All sugar molecules
Answer: A sugar-phosphate backbone (alternating grey-dark grey) joins together nucleotides in a DNA sequence. The sugar-phosphate backbone forms the structural framework of nucleic acids, including DNA and RNA. This backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.

how is population dynamics affected by water pollution
Answer:
As population density increases the demand for the limited fresh water also increases. in most of the case, the water is not treated properly and as such it leads to pollution of surface - level fresh water, and seeps into the ground, polluting ground water as well
