Answer:
Explanation: This process is called mitosis. However, parental gametes – the sperm and egg cells – are unique from all other cells in that they reproduce through a process called meiosis. The purpose of meiosis is to shuffle genetic information and cut the cellular chromosome number in half, from 46 chromosomes to 23 chromosomes. In this way, when an egg and sperm cell combine during fertilization, the resulting embryo will inherit the appropriate amount of unique genetic information from each parent.tion:

What are three methods for detecting radioactively labeled DNA in an experiment?
Answer:
Limitations. detect low abundance DNA binding proteins from lysates. test binding site mutations using many probe configurations with the same lysate. test binding affinity through DNA probe mutational analysis. non-radioactive EMSA possible using biotinylated or fluorescently labeled DNA probes.
Explanation:
Answer:
Proteins interact with DNA through electrostatic interactions (salt bridges), dipolar interactions (hydrogen bonding, H-bonds), entropic effects (hydrophobic interactions) and dispersion forces (base stacking). These forces contribute in varying degrees to proteins binding in a sequence-specific or non–sequence-specific manner.

2. What does it mean if a micrograph is "false-colored?"
It means that the object has color created by the computer since electron microscopes really see in black and white. ... They usually range in sizes between 5-50 micrometers, they are surrounded by a cell membrane, and usually can't be seen without a microscope.
A micrograph is said to be false-colored when there is color created by the
computer involved in the printing of the picture.
A micrograph is a pictorial representation of objects seen under a
microscope. The view of objects under microscope is usually in black and
white color. The micrograph is therefore meant to also be in black and white.
This is the reason why when there is a color in the micrograph, it is referred
to as being false-colored.

What is the complementary strand of DNA that is made during DNA replication if the template/parent strand of DNA reads ATG GGC CAT?
A. TAC CCG GTA
B. UAC CCG GUA
C. ATG GGC CAT
D. CGA AAT AGC
The complementary strand of DNA that is made during DNA replication if the template/parent strand of DNA reads ATG GGC CAT is TAC CCG GTA. Thus, the correct option for this question is A.
What is DNA replication?DNA replication may be defined as a type of biological process through which two identical replicas of DNA form from one original DNA molecule. This process makes a copy of the DNA in a cell is made before the cell divides.
When it comes to the complementary strand of DNA, either of the two chains makes up a double helix of DNA, with corresponding positions on the two chains being composed of a pair of complementary bases.
For example, if Adenine A is present in the parental DNA, then it should be complementarily bounded to the thymine and vice versa. Similarly, if Cytosine is present in the parental strand of DNA, then it should be complementarily bounded by guanine and vice versa.
Therefore, the correct option for this question is A.

Heat energy is transferred on Earth by the processes of convection, conduction, and radiation. How does heat energy cause materials to move during convection? Complete the sentences below.
It causes denser materials to ______.
It causes less dense materials to ______.
Answer choices are Rise, Sink, Reflect, Absorb.
Answer:
Heat can travel from one place to another in three ways: Conduction, Convection and Radiation. Both conduction and convection require matter to transfer heat. If there is a temperature difference between two systems heat will always find a way to transfer from the higher to lower system.
In heat transfer by convection, heat energy causes denser materials to sink and causes less dense materials to rise.
What is heat transfer?Heat transfer refers to the process by which heat energy is transferred from one point at higher temperature to another at lower temperature.
Heat energy is transferred on Earth by the processes of convection, conduction, and radiation.

The benefit of this study done by the students is that it will provide her with a large amount of information about air pollution in New York City. The area with the highest air pollution, what causes air pollution and other necessary information can be gotten.
Therefore, the option is A.
Which cell has the GREATEST surface area to volume ratio?
O Chicken egg
O Skin cell
O Bacterial cell
O Liver cell
The cell with the greatest surface area to volume ratio is the smallest cell, in this case, the bacterial cell.
As a cell increases in size, the proportional increase in volume is higher than that of its surface area. This tells us that the bigger a cell becomes, the lower its surface area to volume ratio will be.
The chicken egg is just one large cell, the largest cell produced by most animals. The skin and liver cells are much smaller, measuring roughly 25-30 micrometers. However, the smallest of the list by far is the bacterial cell, measuring a mere 1-3 microns. This size tells us that the greatest surface area to volume ratio belongs to the bacterial cell.

Liquid water evaporates or the process of transpiration, forming water vapour that moves through the atmosphere, then comes down as precipitation, either enters the soil or transfers onto the lakes, rivers, oceans, etc.
What is water cycle?The water cycle, also known as the hydrologic cycle or the hydrological cycle, is a biogeochemical cycle that describes the continuous movement of water on, above and below the surface of the Earth.
Moreover, the water cycle shows the continuous movement of water within the Earth and atmosphere. It is a complex system that includes many different processes. Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow.
Therefore, the hydrologic cycle is important because it is how water reaches plants, animals and us! Besides providing people, animals and plants with water, it also moves things like nutrients, pathogens and sediment in and out of aquatic ecosystems.

A student is observing a single-celled alga and knows that it undergoes photosynthesis and respiration. Which question could the student ask to find out how it can do both processes?
The options associated with the question is :
Are the inputs of photosynthesis the same as the outputs of respiration?
Are the inputs of photosynthesis the same as the inputs of respiration?
Is water needed for the processes of respiration and photosynthesis?
Is carbon dioxide needed for the process of photosynthesis?
Answer:
The correct answer is - Are the inputs of photosynthesis the same as the outputs of respiration?
Explanation:
To understand that it is able to perform both the process photosynthesis and cellular respiration by this single cell of alga it is required to understand the process of both processes and how they provided to the alga.
Photosynthesis is the process that converts water and carbon dioxide into glucose and oxygen as the output or products. Glucose is further used in the cellular respiration with oxygen to produce water and carbon dioxide. So it make balance of the inputs and outputs in the both reaction so it can be understand by asking if the inputs of photosynthesis the same as the outputs of respiration?
Photosynthesis and respiration both are shown by algae because they need light to make food.
Algae are a diverse group of predominantly photosynthetic organisms, including cyanobacteria, green algae, and other eukaryotes. They account for more than 50% of the photosynthesis that occurs on Earth. Photosynthetic efficiency is higher in algae than in higher plants. Algae use carbon dioxide for cellular respiration. It binds CO2 and reduces the amount in the atmosphere.
The questions which students can ask are :
Are the inputs to photosynthesis and the outputs to respiration the same?
Are the photosynthesis and respiration inputs the same thing?
Is it true that water is required for respiration and photosynthesis?
Is carbon dioxide required for photosynthesis?
what are algae?A group of photosynthetic, aquatic, marine, true root stems leaves bearing organisms.
thus it concludes algae can perform both cellular respiration and photosynthesis.

Why is the earth considered a magnet? What is a permanent magnet? describes an electromagnet
Answer: *See Explanation*
Explanation: The earth's core "generates" its own magnetic field....so it is considered a magnet. A good example of a "Permanent Magnet" would be the Earth's crust. Not the crust itself, but the effect it causes. A "Electromagnet" is made by passing electric currents through a coil surrounding it. (I know, it's a bit confusing.) Check other sources if it is too confusing.
