Explanation:
Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth.In the atmosphere, as air warms it rises, allowing cooler air to flow in underneath. Along with the turning of the Earth, this movement of air creates winds. Winds, in turn, create surface waves on the ocean.Convection also plays a role in the movement of deep ocean waters and contributes to oceanic currents.Inside Earth, the convection of mantle material is thought to cause the movement of the overriding crustal plates, resulting in events such as earthquakes and volcanic eruptions.Description of a ladybugs metamorphosis, including whether it is complete or incomplete

The base pairing rule for DNA is adenine (A) pairs with thymine (T), and guanine (G) pairs with cytosine (C).
When RNA copies the DNA, the base pair for adenine changes to _______ instead of thymine.
Question 5 options:
Thymine
Uracil
There is no new base
U.. Something Or Another...
Answer:
Uracil
Explanation:
DNA molecule is made up of monomeric nucleotides, which are of four different types viz: Adenine, Guanine, Cytosine, and Thymine. According to the COMPLEMENTARY BASE PAIRING RULE as proposed by Chargaff, these nucleotides pair in the DNA as follows: Adenine to Thymine (A-T), Guanine to Cytosine (G-C).
However, in the RNA molecule (second nucleic acid), a fifth nucleotide called URACIL is found. This URACIL replaces thymine because thymine is only found in DNA while Uracil is only found in RNA. When DNA is transcribed into mRNA, Adenine nucleotide gets transcribed into Uracil in the RNA instead of thymine i.e A to U.

Uracil

Which of the following statements about oceans is incorrect?
A) Oceans collect water from other reservoirs including streams and rivers.
B) Oceans are the main source of drinking water on Earth's surface.
C) Oceans are connected to other reservoirs through evaporation and precipitation.
D) Oceans are the main type of reservoir that contain salt water.
Answer: C
Explanation:
It made sense.
Answer:
B
Explanation:
B is incorrect because oceans are not the main source of drinking water. They contain the most water, but the ocean is not drinkable as it is much too salty and would lead to dehydration and the shriveling up of cells, causing death if it was the only water you drank. Usually only small island countries will have to resort to drinking ocean water after desalinating it, but most of the world gets their water from other sources such as groundwater, springs, lakes, and rivers.

A student makes a new gel using agarose, water, and buffer solution. The student loads their DNA samples in their wells and places the gel in the chamber for an appropriate length of time. When the student places the gel on the UV lightbox, no DNA bands show up at all. Even the marker lane is clear and has no bands! What mistake did the student make? Explain your answer.
Answer:
A dye needs to be added to the gel electrophoresis
Explanation:
Ethidium bromide (EtBr) is a reagent that adheres to DNA and fluoresces under ultraviolet (UV) light. Due to this feature, EtBr is widely used to dye DNA strands in molecular biology techniques such as agarose gel electrophoresis. The most common dyes for visualizing and staining nucleic acids during gel electrophoresis include EtBr, SYBR gold, Eva green and SYBR safe. If EtBr (or any other staining agent) was not added to the electrophoresis gel and/or running buffer, the gel will be dark under UV light (even the ladder lane will look empty) because DNA has not been stained.
The mistake the student made was by not adding dye to the sample. Dyes
are commonly used during electrophoresis.
Agarose gel electrophoresis is the process which helps in the separation
and purification of DNA samples. This process involves the use of dyes
which acts as markers.
in this scenario, we were told no DNA bands show up and the marker lane is
clear means no dye was added. The common dye used in agarose gel
electrophoresis is Ethidium bromide (EtBr) which should be added by the
student.

Why does the swing of a pendulum become lower over time? (site 1)
When the swing is raised and released, it will move freely back and forth due to the force of gravity on it. The swing continues moving back and forth without any extra outside help until friction between the air and the swing and between the chains and the attachment points slows it down and eventually stops it.

What is an amino acid?
Answer:
the other person is right
Explanation:
the energy required to lift an object is supplied by ATP, which is made by breaking down molecules of
a. carbon dioxide
b. oxygen
c. glycolysis
d. glucose
The energy provided by ATP is driven by the breakdown of glucose molecules. Thus, option D is correct.
ATP or Adenosine triphosphate is the energy molecule that is able to provide energy to the body. Varying pathways and cycles in the cell produce ATP.
Which molecules produce ATP?ATP production is carried out in the degradation of the complex molecules by the cell. The cycle is operated primarily in the cell for the production of ATP in glycolysis.
The ATP is produced in the glycolysis cycle with the breakdown of glucose molecules. Thus, option D is correct.

Each cube represents a cell. Which cell would probably have the easier time moving materials into and out of itself quickly enough to survive?
Hello. You did not present the cubes to which the question refers, which makes it impossible for me to be able to answer your question exactly, but I will try to help you in the best possible way.
The cell that will have the easiest movement of materials in and out of itself is the cell with the smallest size. This is because, smaller cells have a proportional surface area and volume. This helps in absorbing everything the cell needs, with impressive speed, as well as facilitating the removal of substances harmful to the cell.
