Hydrogen bonds, type of chemical bond exists between two water molecules.
What is a chemical bond?A chemical bond is what binds atoms in molecules together. Electrical forces between positive charge atomic nuclei and negative-charged electrons form bonds. A chemical bond is a long-lasting attraction between ions or atoms that allows molecules and crystals to form.
Hydrogen bonds arise between neighboring water molecules' hydrogen and oxygen atoms. A hydrogen bond is formed by the attraction of individual water molecules. A water molecule is made up of two hydrogen and oxygen atoms atom, with one partly positive hydrogen atom connected to a more highly electronegative atom.

A) ionic bondsB) hydrogen bondsC) covalent bondsD) valence bondsDescribe the advantage of broad-leaved trees losing their leaves as winter sets in and the advantage of needle-leaved trees keeping their leaves if they are in poor soil
Answer:
The advantage of shedding broad leaves in the winter is to conserve the energy that needs to expand in order to provide heat to each part of the plant including leaves as in winters it becomes very dry and cold. If they do not shed their leaves they have to spend more energy to spend energy on leaves.
Needles like leaves have a thick cuticle layer that prevents from losing water in dry conditions or conditions with a limited amount of water in the soil. These leaves also help in photosynthesis by capturing more sunlight as they have a larger surface area. These adaptions can live in poor soil, rain and snowy conditions.
The two lower chambers of the human heart are known as:
a.
atriums
c.
auricles
b.
ventricles
d.
blood vessels
Answer:
b. ventricles
The right and left ventricles
Answer:
B(ventricles)
Explanation:
So lets go over the heart.
First blood circulates from your body to your heart. This is through blood vessels. These blood vessels are connected to the inferior and superior vena cava that go into the heart.
So, this means that the blood vessels are outside of the heart, not the lower areas.
Then, the blood goes into the right artierium, and down to the right venticle. So, thinking about this, it means that the artieriums are the top chambers.
The word auricles is another word for artiums, which we already know are the top chambers.
The venicles are below this, these must be the bottom chambers.
I attached files of some notes I took on the heart, they show the strucutre of the heart and the workings of the heart and circulatory system.
Hope my answer or notes helps! ;)
How would blood flow be affected if the aorta decreased in diameter?
Answer:
A decreased diameter means more of the blood contacts the vessel wall, and resistance increases, subsequently decreasing flow. The influence of lumen diameter on resistance is dramatic: A slight increase or decrease in diameter causes a huge decrease or increase in resistance.

During cellular respiration, organisms convert different kinds of food into glucose. Cells then break down the glucose to provide energy for life activities. Which of these substances is also produced during cellular respiration?
A. Carbon dioxide
B. Fat
C. Oxygen
D. Protein
Fat, of these substances is also produced during cellular respiration. Thus, option (b) is correct.
What is respiration?Respiration is the transmission of oxygen from the outside world to cells within tissue, as well as the elimination of carbon dioxide in the reverse direction. It is a physiological reaction that occurs within living creatures' cells. We can breathe because of our lungs and respiratory system.
Glycerol is converted into one of the intermediates of glycolysis and hence enters the aerobic respiration pathway. Fats are a fuel for cellular respiration. It provides the most energy among lipids, carbs, and proteins. Fat is a triglycerides molecule.
As a result, the fat, of these substances is also produced during cellular respiration. Therefore, option (b) is correct.

This is the original strand of DNA: ATG AAG TTT GGC TAA
Which option would represent a frame shift mutation due to deletion during replication?
Answer:
ATG AAG TTG GCT AA
Explanation:
I took the test
A genetic modification in which there is an acquisition and omission of nucleotide base in the series is called frame-shift mutation.
It modifies the reading frame of the series that can vary the amino acid sequences and the protein that it forms.
The correct answer is:
ATG AAG TTG GCT AA
This can be explained as:
In the sequence given in the question ATG AAG TTT GGC TAA there is a deletion mutation in the Thymine (T) nucleotide.The deletion of thymine (T) causes the reading frame of the three-nucleotide to change and the reading pattern gets altered.The frame now changes and the reading will start with altered three base pairs.So, the sequence ATG AAG TTT GGC TAA will be mutated to ATG AAG TTG GCT AA.

How are gene and protein sequences used to classify organisms?
Answer:
"Genes code for proteins and each organism has different genes."
Explanation:
"Sequences of genes are used to identify differences and similarities between organisms. So it can be used to identify related organisms, because they show differences between species.
DNA acts as set of instructions for building an organism, because it contains the genetic instructions to make for proteins. Genes are made of DNA and each one codes for a different protein. In that way, different types of organisms can all be differentiated through their genes.
This is because the translation of proteins from DNA is guided by a universal code. It means, the same codons codes for the same amino acid across all species."

Hello. Your question is incomplete. The complete question asks for the correct answer to be found based on Catalase is an essential enzyme in living beings since all cells need it.
Answer:
B. Cells only function within a specific temperature range because enzymes only function within a specific temperature range.
Explanation:
Catalase needs to be present in all cells of the living organism because it is responsible for the decomposition of hydrogen peroxide that cannot stay inside cells for long periods of time. Following this type of reasoning, we can say that it is necessary to maintain a constant temperature for the enzymes of an organism to function well because all enzymes have a specific temperature range, even catalase.
The specific temperature range determines that the enzymes will only work within that range. Therefore, an environment where the temperature is below or above that specific range, can prevent the enzyme from functioning and even cause irreversible damage to the enzyme.
