Answer:
FACTORS INFLUENCING CHEMICAL BONDS
Ionic bonding is a chemical bond between a positive ion and negative ion. Ionization energy, electronegativity, and lattice energy are the factors that influence the formation of ionic bonds of elements.
CHARACTERISTIC OF IONIC BONDS
Ionic compounds are hard and brittle. Ionic compounds dissociate into ions when dissolved in water. Solutions of ionic compounds and melted ionic compounds conduct electricity, but solid materials do not. An ionic compound can be identified by its chemical formula: metal + nonmetal or polyatomic ions.
CHARACTERISTIC OF COVALENT BOND
Covalent compounds have bonds where electrons are shared between atoms. Due to the sharing of electrons, they exhibit characteristic physical properties that include lower melting points and electrical conductivity compared to ionic compounds.

The picture below shows a land surface in a location in Florida.
Which of these most likely caused the cavities in the land surface?
shifting of tectonic plates
dissolving of rocks by groundwater
lack of water during long periods of drought
breaking up of rocks due to high temperature
Answer:
I think is B as well.. c:
Explanation:
These crevices frequently appear when a construction crew buried organic waste, including tree branches, brush, stumps, and building supplies. Thus, option B is correct.
What caused the cavities in the land surface?Rainfall that seeps through the soil absorbs carbon dioxide and combines with decomposing vegetation to produce water that is just a little acidic.
This subsurface water progressively dissolves limestone while forming a network of holes and cavities as it travels via fissures and cracks.
After a few years, the degradation of this buried waste produces a sizable underground void that is concealed by a thin layer of flora and soil.
Sinkholes can be created when water from a damaged pipe seeps through mud and rocks and erodes the ground below.
Therefore, dissolving of rocks by groundwater caused the cavities in the land surface.

In her report of an investigation, shira states that the height of a bush is 0.65 meters. Nathaniel states that the height of the same bush is 65 centemeters. How do the statements of the two students compare?
Answer:
See the answer below
Explanation:
The statements of the two students are the same, just that they used different units for the height.
100 centimeters is equivalent to 1 meter
65 centimeters would be equivalent to 65 x 1/100
= 0.65 meters
Hence, 0.65 meters and 65 centimeters are the same height but with different units.

what are the scientist doing incorrectly? what could they do to make their work in the lab safer? why is it important to follow these procedures? part b
Answer:
What the scientist is doing incorrectly is hitting a rock with a hammer without protective equipment and on the same table where containers with chemical or biological substances are found.
Explanation:
Biosafety is an important aspect of laboratory work. Conducting studies in rocks, trying to fracture them with the use of a hammer is an incorrect practice carried out by a scientist when he does not use protective equipment and has containers with substances on the same work table.
what could he do to make their work in the lab safer?Wear gloves, protective apron and protective eyewear.Break the rock on a work table where there are no containers that could break by accident, spilling their contents.why is it important to follow these procedures?It is important to follow these procedures because injuries to hands, body or eyes can be avoided by fracturing the rock. In addition, it prevents the breakage of containers with chemical or biological products, which could contaminate the work area or cause damage to the scientist.

explain why a fresh wound on the skin bleeds more on a hot day than a cold day
Answer: This is more of a guess based on what I already know about liquid in certain temperatures but I would say it would have to be related to the blood having a harder time congealing due to the molecules moving faster because of the temperature. You probably already know that atoms move faster in higher temperatures as opposed to cooler ones, therefore the process of congealment and essentially transitioning from liquid to solid would be easier/quicker in cooler temperatures where the atoms in and around the wound would be moving slower.

which best decribes how proteins form?
a. nucleic acids are linked together
b. peptides bond to nucleic acids
c. amino acids form peptide bonds
s. nucleic acids bond to amino acids
Answer:
I think its c ?
Explanation:
amino acids form with peptide bonds in order to make a chain kind of, that's the easiest way to explain that
The best description that how proteins form is amino acids form peptide bonds. Thus, option C is correct.
What are the types of amino acid?The three amino acids, lysine (Lys), arginine (Arg), and histidine (His), on the other hand, are regarded as basic amino acids. These amino acids are classified as basic because they include basic amine groups (-NH2) in their side chains that can accept a hydrogen ion (H+) from the environment. It is significant to remember that amino acids can become more basic or acidic depending on the pH of the surroundings.
Aspartic acid (Asp) and glutamic acid (Glu) are the two amino acids that are regarded as acidic amino acids. These amino acids are acidic due to the Carboxylic acid group (-COOH) in their side chains, which has the ability to donate a hydrogen ion (H+) to the environment.
Therefore, The best description that how proteins form is amino acids form peptide bonds. Thus, option C is correct.

Write and discuss brifely the basic application and implication areas of major branchs of psycology
Answer:
Psychology is the academic discipline concerned with the inner life (knowing, feeling and striving) and the behavior of people. It generally does this by following the scientific method, but in some cases it makes use of symbolic interpretation and critical analysis, following the example of other social sciences.
The goal of psychology is to acquire knowledge about the behavior of humans, both in their everyday environment and under special circumstances. With the emergence of the behavioral movement, the object of psychology was reduced to the outwardly observable and measurable behavior of animals humans, because the inner life would not be objectively registered by scientific observation, but only subjectively by introspection and understanding. This limitation has been reversed, among other things by the 'cognitive revolution' in psychology, by the great social importance of psychotherapy and by the connotations that the word 'psychology' evokes in everyday language use.

ATP and ADP both play a role in cellular reactions involving energy. How are these two molecules related?
A Adding a phosphate group to ADP produces ATP and releases energy.
B. ATP breaks down to produce ADP and a phosphate group, releasing energy
C. ADP breaks down to produce ATP and a phosphate group, releasing energy
D. Adding a phosphate group to ATP produces ADP and releases
Answer:
A
Explanation:
You can see it in the picture:
The molecules of ATP and ADP are related to one another in the sense that the breaking down of ATP produces ADP and a phosphate group, releasing energy. Thus, the correct option for this question is B.
What is the process of adding a phosphate group called?The process of adding a phosphate group to any organic compound such as glucose, ADP, etc. is known as phosphorylation. This process increases the catalytic activity and downstream process of cell signaling.
Eliminating one phosphate from ATP in order to convert it into ADP liberates energy. This is because breaking one phosphoanhydride bond liberates approximately 7.3kcal/mol of energy. While the addition of a phosphate group to ADP in order to produce ATP requires some utilization of energy.
Therefore, ATP breaks down to produce ADP and a phosphate group, releasing energy is a statement that represents a relation between ATP and ADP. Thus, the correct option for this question is B.

that directs the ribosome to build certain--------------------
as needed by specific cells or situations.
Answer:
DNA contains genes that can be read to create messenger RNA that directs the ribosome to build certain proteins as needed by specific cells or situations.
Explanation:
DNA is a nucleic acid that contains in its structure a specific sequence of nucleotides, whose quantity and order determine the genetic information of an individual. A chromosome consists of a DNA molecule, and each fragment of this molecule constitutes genes with specific instructions for determining structural and functional characteristics.
Transcription is the process by which DNA can be read and transcribed into messenger RNA (mRNA), a molecule that carries the genetic code to the ribosomes for protein synthesis, in a process called translation.
When a cell needs to synthesize a specific protein, transcription and translation mechanisms occur so that the protein can be synthesized.

describe the relationship between genotypes and phenotypes
Answer:
Genotype is the potential, it is the set of genes.
Phenotype is the expression of those genes, showing the dominant/ activated gene.
For example, my mother and members of her family are short with hazel eyes and dark hair.
My dad and his family are tall, with brown eyes and dark hair.
I will have genes for height that vary- short or tall. I will have genes for eyes hazel or brown.
I will have genes for hair- dark.
You don’t know, based on what i’ve told you, what my height or eye colour is. That’s my genotype.
I am tall, with hazel eyes and dark hair. That’s my phenotype.
This is really over simplified, but it should help you understand.
Genotype is the blueprint/ building plans. Phenotype is the building.
