Answer:
Peptide Bonds
Section 3.2Primary Structure: Amino Acids Are Linked by Peptide Bonds to Form Polypeptide Chains. Proteins are linear polymers formed by linking the α-carboxyl group of one amino acid to the α-amino group of another amino acid with a peptide bond (also called an amide bond).
Explanation:
plss followed me:)
Peptide bond is the answer.
What is it?
It's a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water (H2O).

As usually the process of cell division involves the idea of the cell arising from other cells and mostly stem cells undergo mitosis which again is a process of cell division hence demonstrating that the cell arise from other cells either through division.
What part of a nuclear fuel rod is reused for nuclear weapons after its spent?
A-Uranium
B-Plutonium
Answer:
Uranium
Explanation:
I had it on a quiz
Plutonium is the wasted portion of a nuclear fuel rod which is reused for nuclear weapons. So, the correct option is B.
What is Plutonium?Plutonium-239 is an explosive substance that may be used as nuclear reactor fuel or as a nuclear bomb explosion. It is created from uranium-238 in nuclear reactor fuel rods via a process known as nuclear transmutation. When uranium-238 receives a neutron, it is transformed into plutonium-239, which can fission and release energy.
The plutonium-239 produced in a nuclear reactor is utilized as fuel, together with uranium-235, to continue the nuclear chain reaction. The plutonium-239, on the other hand, may be extracted from spent nuclear fuel and refined for application in nuclear weapons. Nuclear reprocessing is a contentious problem due to the concerns of nuclear proliferation and the possibility for nuclear terrorism.
Therefore, the correct option is B.

Explain why the science of bite mark analysis IS or IS NOT as “exact as other types of forensic science.
Answer:
Bite marks are a little easier to identify and don't require DNA identification
Explanation:
When the Bite marks are a little easier to identify and also they don't require DNA identification.
What are Bite Marks?
The bite-mark research is extremely difficult, with many elements involved in a forensic dentist's capacity to define the identity of the perpetrator.
The activity of a person's jaw and tongue when he or she bites contributes to the kind of effect that is left.
Though the science after bite marks has been debunked, it resumes being used in courts. And when introduced as scientific proof by so-called professionals in court, bite marks seem to show jurors a false sense of certainty.

A high rise condominium is planned for a barrier island that lies off the southwest coast of Florida. Which of these predictions could be made about the impact this construction will have on the sustainability of the coastal ecosystems?
Group of answer choices
Predators will abandon the habitat as humans are the top predator in any ecosystem.
The ecosystem will be destabilized as abiotic resources like available space are reduced.
The costal ecosystem populations will decline until new species evolve that are adapted to live new humans.
Key species found on the barrier island will move to a new habitat.
Answer:
The ecosystem will be destabilized as abiotic resources like available space are reduced.
Key species found on the barrier island will move to a new habitat.
Explanation:
Due to living of humans on the barrier Island with adversely affected the organisms present on that Island because the loss of habitat occur due to living of humans and the important species migrated to other habitats where no humans are present. So this action greatly change the environment of barrier Island and the ecosystem will be destabilized.
Choose one of the statements below that is true
A sugar farm near the coast of Florida applies a nitrogen based fertilizer to their soil three times a year. When rain falls on these fields after it has been fertilized some of the fertilizer runs off into the ocean causing the nitrogen levels in the water to increase. The increase levels of nitrogen can lead to many ecological effects beginning with the rapid growth of algae. This process is known as eutrophication.
How can eutrophication affect other organisms in the water?
Group of answer choices
The algae provide food for fishes and other organisms, leading to decreased algae populations.
The oxygen in the water is used up as algae is decomposed, reducing the amount available to other organisms.
The water becomes better able to support aerobic organisms.
The extra nitrogen provides additional food for the other organisms, increasing their population.
Answer:
The algae provide food for fishes and other organisms, leading to decreased algae populations
Explanation:
Excessive nutrients lead to algal blooms and low-oxygen (hypoxic) waters that can kill fish and seagrass and reduce essential fish habitats. ... Eutrophication sets off a chain reaction in the ecosystem, starting with an overabundance of algae and plants.

5. A dedicated earth science student using
an aneroid barometer measures the air
pressure at the base of Slide Mountain
as 1016.0 mb. At the same time another
dedicated earth science student measures
the pressure at the top of the mountain.
Which pressure reading could be correct
at the top of Slide mountain?
(1) 1016.0 mb (3) 1025.7 mb
(2) 988.5 mb (4) 1040.0 mb 5
Answer:
(2) 988.5 mb.
Explanation:
The air pressure descends as we ascend. In other words, they are inversely proportional.
The air pressure descends as we ascend the mountain because the air molecules that are above us in high altitudes are fewer than the number of air molecules that are above us in the base of the mountain. So, the exerted pressure of the molecules on ourselves is lower in high altitudes.
Due to the reason mentioned above, we can deduce that the only correct option is option number two since the other ones show increasing or the same pressure, which is not possible as we ascend.
A barometer is an instrument that is designed for measuring the changes in air pressure.
The aneroid barometer has metal chamber as when the air pressure increases the walls of metal push in and when the pressure is low they come out. The chamber is connected by the springs and needle. If the pressure of the base of a mountain is about 1016.0 MB. The pressure of the top of the mountain is 1025.7 MBHence the option 3 is correct.
