The cycle that is critical for the formation of organic compounds is the ___cycle.
Atoms of two different elements must have o ferent
electrical charges.
numbers of neutrons.
o atomic numbers.
O energy levels.
Answer:
atomic numbers
Explanation:
In order for two atoms to be different, they have to have a different number of protons. Protons are represented by the atomic number. Thus, atoms of two DIFFERENT elements must have different atomic numbers.

what's the difference between pseaudscience and science
Answer:
hope it helps..
Explanation:
Pseudoscience is differentiated from science because – although it claims to be science – pseudoscience does not adhere to accepted scientific standards, such as the scientific method, falsifiability of claims, and Mertonian norms.

What does the measurement 45 N represent in the photograph?
Answer:
The magnitude(size) of a force
Explanation:
Apex
The measurement of 45 N represents the magnitude of force in the photograph.
What is force?Force is defined as a cause which is capable of changing the motion of an object. It causes an object which has mass to change it's velocity. It is also simply a push or a pull . It has both magnitude as well as a direction.Hence, it is a vector quantity.
It has SI units of Newton and is represented by'F'.Newton's second law states that force which acts on an object is equal to momentum which changes with time. If mass of object is constant, acceleration is directly proportional to net force acting on an object.
The concepts which related to force are thrust and torque .Thrust increases the velocity of an object while torque produces change in rotational speed of an object.

How are DNA tests useful to solve a more mystery? Explain in your own words.
Explanation:
forensic scientists can compare DNA found at the crime scene from blood or hair to DNA samples taken from suspects if there is no match they may be able to rule out that suspect. if there is a match police would likely want to take a closer look.
Students in Mr. Painter's science class studied samples of pond water using a microscope. To prepare for the experiment, the students placed a drop of pond water on each microscope slide, and then covered the drop with a cover slip that was marked with a 1 mm grid. Using the microscope to view the slides, students counted how many of each type of organism they found in each 1 mm square. Finally, each student calculated the total number of each type of organisms. Their data is shown below. Which organism is the least plentiful in the pond water studied? A. amoeba B. volvox C. euglena D. paramecium
Answer:
Euglena
Explanation:
the least plentiful organism in the pond water studied. Each student found fewer euglena than any other organism.
Explain the process of DNA isolation.
Answer:
Lysis, precipitation and purification
Explanation:
DNA isolation is a molecular biology technique based on the extraction of DNA and subsequent purification to remove inhibitors that may hamper the process of amplification. DNA isolation consists of three steps:
1- Lysis: it consists of the mechanical disruption of the cell, where the nucleus is broken to release DNA. During this process, it is required to use enzymes and detergents such as Proteinase K
2- Precipitation: during this process, the DNA is precipitated by using alcohol and salt.
3- Purification: this process removes the impurities from DNA. Extraction is carried out by washing DNA with ethanol and water.

Which of the following occurs just before the cell enters the G2 stage of
the cell cycle? *
O The nuclear membrane disintegrates.
O DNA replicates
O Centrioles form
O The nucleolus divides
Answer:
DNA replicates
Explanation:
S phase (Synthesis Phase) During this phase, the cell makes a variety of proteins that are needed for DNA replication. During S phase, which follows G1 phase, all of the chromosomes are replicated. Following replication, each chromosome now consists of two sister chromatids, the synthesis phase of interphase takes the longest because of the complexity of the genetic material being duplicated. Throughout interphase, nuclear DNA remains in a semi-condensed chromatin configuration

How do polar bear adapt to its environment?
Answer:
Polar bears have thick fur coats that help keep them keep warm in cold conditions. They have a dense layer of fur close to the skin and an outer layer of longer fur. The inner layer isulates them against the cold. ... The skin underneath their fur is black and absorbs the heat from sunlight, helping them stay warm.
Explanation:
The way polar bears adapt to their environment is because of their thick warm coat.
1. Which type of reaction has water in its products?
a. Hydrolysis
b. Dehydration synthesis
2. What type of reaction uses water as a reactant?
a. Hydrolysis
b. Dehydration synthesis
Answer:
1. b. Dehydration synthesis
2. a. Hydrolysis
Explanation:
Hydrolysis is the process where water is used to break chemical bonds. Dehydration synthesis is the reverse reaction, where a bond is formed resulting in the loss of water from the molecule, so a water molecule is generated as a product.
That means that dehydration synthesis produces water, and hydrolysis uses water.
Answer:
b. Dehydration synthesis gives out water as a product.
a. Hydrolysis reaction uses water as a reactant.
Explanation:
b. Dehydration synthesis can be defined as, formation of larger molecule from small reactant, followed by loss of water from the reaction.
They are also called condensation reactions.a. Explanation: Hydrolysis, it is the reaction in which compound is interacted with water which results in the degradation of that particular compound.
