Answer:
The Sit and Reach Test
Explanation:
The Sit and Reach Test is one of the linear flexibility tests which helps to measure the extensibility of the hamstrings and lower back. It was initially described by Wells and Dillon in 1952 and is probably the most used flexibility test.

how are plant and animal cells similar in structure
Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes. Both also contain similar membranes, cytosol, and cytoskeletal elements.
Explain how homologous structures are used as a source of evidence to infer evolutionary relationships between modern and fossil organisms
Answer:
Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations.
Explanation:
Analogous structures demonstrate that identical selective pressures might result in similar adaptations, whereas homologous structures indicate evidence for shared ancestry.
What are analogous structures?In contrast to homologous structures, analogous structures are characteristics of different species that have evolved in response to a similar environmental challenge and are similar in function but not necessarily in structure.
While comparable structures demonstrate that similar selective pressures can result in similar adaptations, homologous structures suggest that they have a common ancestor (beneficial features).
Therefore, homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations.

Label the following with
N (neutron), P (proton),
E (electron)
___Negative charge
___ Atomic number ___determination
___ Atomic mass determination
___ Involved in bonding
___ Positive charge
___ when gained or lost creates ions
___ Neutral charge
___ Found in nucleus
Answer:
E, P, N and P, E, P, E, N, N and P
Explanation:
I am pretty sure the answers would go like this (in the order you have here):
1. Electron (they have a negative charge)
2. P (The atomic number is determined by the number of protons)
3. N and P (The atomic mass is determined by how many Neutrons and Protons there are in the atom)
4. Electron (they are usually involved in bonding)
5. Proton (they have positive charge)
6. Electron (ions are created when an atom has gained or lost electrons)
7. Neutron (they are neutral)
8. Both Neutrons and Protons (they stick together inside the nucleus)
I am not entirely sure why the atomic number determination has 2 blanks since it is only determined by protons, but I hope this helps. I havent studied this for a while but those are the best answers I can provide and have checked them with my books so I hope they are correct. Good Luck!

ATP hydrolysis is the lysis of the molecule mediated by water. It releases a phosphate group and energy. It is a reversible reaction. (a) Reversible ATP hydrolysis. (b) added energy on the left and released energy on the right.
------------------------
ATP is a significant molecule involved in many of the cellular metabolic routes. These metabolic processes can either form it or break it.
ATP provides energy to many different functions in the organism.
ATP means adenosine tri-phosphate. It is composed of adenosine (an adenine plus a ribose), and three phosphate groups.
Note: you can also find adenosine Diphosphate (two phosphates) and adenosine monophosphate (one phosphate).
Oxygens from the phosphate groups only have a single bond to phosphate (there are no hydrogen bonds).
These single bonds, known as phophoanhydrid bonds, have a negative charge and tend to repel each other, making the molecule unstable.
So phosphate groups repel each other, and a considerable amount of energy is applied to keep them united. So phophoanhydrid bonds are high energetic bonds.
The forces that keep the phosphate groups together accumulate potential energy.
If these bonds are broken, part of this potential energy would be released.
When talking about breaking the molecule, we are referring to ATP hydrolysis. And the released energy is used in different cellular processes that require energy.
ATP Hydrolysis is the molecule lysis mediated by a water molecule.
ATP + H₂O ⇄ ADP + Pi + Energy
Pi is the released inorganic phosphate group.
This is a reversible reaction, meaning that the ADP can go back to ATP.
ADP + Pi + Energy ⇄ ATP + H₂O
(a) What is this a model of?
This model represents the reversible ATP hydrolysis.
In the superior part of the image, we can see an ATP molecule composed of adenine, ribose, and three phosphate groups. The yellow star behind represents the accumulated energy.
When ATP hydrolysis, it loses a phosphate group and part of the energy that was keeping this group in the molecule.
An ADP is composed after hydrolysis. We can see this molecule in the inferior area of the image.
ADP molecule is composed of adenine, ribose, and two phosphate groups.
Because hydrolysis is a reversible process, by adding a new phosphate inorganic group and energy, we can get a new ATP.
(b) Explain how you would change the model to make it correct?
What is wrong with this model is that instead of showing released energy during the hydrolysis process, it shows energy added to the reaction. In the same way, instead of showing added energy to the reversible reaction, it shows released energy.
Added energy and released energy must be changed.
Added energy should be on the leftReleased energy should be on the right---------------------------------

DNA and RNA are ______ that serve as templates that form proteins
Answer:
In the first step, the information in DNA is
transferred to a messenger RNA (mRNA)
molecule by way of a process called
transcription.... The mRNA sequence is
thus used as a template to assemble-in
order-the chain of amino acids that form a
protein.
A type of RNA that is called as ribonucleic acid type called as transfer RNA that is used for the production of the amino acid at a time and the protein assembly takes place at the ribosomes.
What is the role of DNA and RNA for the sake of protein synthesis ?
DNA are responsible for the providing out the code for the cell's activities and the RNA are responsible for providing out the service to make them proteins.
Each group of 3 bases in the mRNA constitutes a codon and each codon is specifying a particular type of amino acid. The mRNA sequence therefore used as a template to make the assembly in order of the chain of amino acids which form a protein.
It is found that in all biological cells , usually occurs in cytoplasm of cell though its production takes place in nucleus. Whereas DNA is providing the code for cell's activities and RNA is responsible for converting that code into proteins which carry various cellular functions.
