Answer:
Celery Stalk would be made of Cellulose, as it has a Rigid Cell Wall. This gives it it's chewy and hard texture. Plants as a whole also contain Chloroplasts and a Vacuole which Animal Cells do not. The Chloroplasts contain Chlorophyll which job is to absorb Light Energy and carry out Photosynthesis. The Vacuole stores Cell Sap which holds the salts and sugars needed for the Plant. A Skin Cell will not contain these three Organelles, but will contain a Nucleus, Cytoplasm, Mitochondria, Ribosomes, Cell Membrane as do Plant Cells. Below shows the function of these Organelles that both Plant and Animal Cells contain:
Nucleus - Holds DNA for Cell and controlles the Cells Activities
Cytoplasm - Where most Chemical Reactions take place
Mitochondria - To carry out Aerobic Respiration to store Energy for the cell
Ribosomes - To carry out Protein Synthesis
Cell Membrane - To control what substances enter or leave the cell
Explanation:
This is probably way more information than you needed, however hopefully you get the idea! I do tend to 'waffle' a bit so apologies XD!
The contrasting cellular landscapes of a celery stalk and a human skin cell reveal a striking divergence in structural complexity and function. The celery stalk's cells boast a straightforward architecture, characterized by a central vacuole responsible for maintaining turgidity and storing nutrients, while chloroplasts play a pivotal role in photosynthesis.
In stark contrast, human skin cells exhibit a multifaceted arrangement, comprising a nucleus that governs genetic information, mitochondria driving energy production, and an intricate network of keratin filaments providing structural integrity. These distinct cellular compositions highlight the diverse adaptations that cells have developed to fulfill specific physiological requirements in both plant and animal organisms.

12. A farmer is struggling to control the population of a certain insect on his farm. After researching population control techniques, he discovers that a particular bird is a predator of this insect. The farmer purchases a number of these birds and releases them onto his farm. How might the farmer's action most likely have a negative impact on the ecosystem
The farmer's action most likely have a negative impact on the ecosystem because may be there is no predator or controlling agent of that bird.
Why introduction of new bird cause problem?We know that one organism is responsible for controlling the population of other organism so if such type of controlling agent is present, the organism grow rapidly and can harm the whole ecosystem.
So we can conclude that farmer's action have a negative impact on the ecosystem due to presence of no predator or controlling agent of that bird.

6)Twist your model and explain how it is a helix
7)Explain how Muslims can understand DNA from the Islamic Worldview
Answer:
DNA
DNADNADeoxyribonucleic acid is a polymer composed of two polynucleotide chains that coil around each other to form a double helix carrying genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses. DNA and ribonucleic acid are nucleic acids.
2) (i) A pentose sugar is a monosaccharide with 5 carbon atoms. Pentose sugars are the deoxyribose sugars, which are part of nucleotides in DNA
(Ii) a phosphate is an anion, salt, functional group or ester derived from a phosphoric acid. It most commonly means orthophosphate, a derivative of orthophosphoric acid H ₃PO ₄. The phosphate or orthophosphate ion [PO ₄]³⁻ is derived from phosphoric acid by the removal of three protons H⁺
Formula: PO₄³⁻
Molar mass: 94.9714 g/mol

Beilstein Reference: 3903772
Conjugate acid: Monohydrogen phosphate
Gmelin Reference: 1997
(III) Nucleobases, also known as nitrogenous bases or often simply bases, are nitrogen-containing biological compounds that form nucleosides, which, in turn, are components of nucleotides, with all of these monomers constituting the basic building blocks of nucleic acids.
3) purine nitrogenous bases:-
Purines and Pyrimidines are nitrogenous bases that make up the two different kinds of nucleotide bases in DNA and RNA. The two-carbon nitrogen ring bases (adenine and guanine) are purines, while the one-carbon nitrogen ring bases (thymine and cytosine) are pyrimidines.
pyrimidine nitrogenous bases
Pyrimidine: A nitrogenous base similar to benzene (a six-membered ring) and includes cytosine, thymine, and uracil as bases used for DNA or RNA.
The pyrimidine bases are thymine (5-methyl-2,4-dioxipyrimidine), cytosine (2-oxo-4-aminopyrimidine), and uracil (2,4-dioxoypyrimidine)
4) Explain Chargaff's rules for base -pairing
Chargaff's rules state that DNA from any species of any organism should have a 1:1 stoichiometric ratio of purine and pyrimidine bases (i.e., A+G=T+C ) and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine.
5)Identify what objects/colors you used for your DNA Model
The four nitrogenous bases that compose DNA nucleotides are shown in bright colors: adenine (A, green), thymine (T, red), cytosine (C, orange), and guanine (G, blue).
6)Twist your model and explain how it is a helix
Double helix is the description of the structure of a DNA molecule. A DNA molecule consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating groups of sugar (deoxyribose) and phosphate groups.
The double helix of DNA is, like its name implies, in the shape of a helix which is essentially a three dimensional spiral. The double comes from the fact that the helix is made of two long strands of DNA that are intertwined—sort of like a twisted ladder.

In conditioning, during the sequence of delaying the stimulus, the dogs often displayed____ anxiety or excitement
In conditioning, during the sequence of delaying the stimulus, the dogs often displayed anticipatory anxiety or excitement. Therefore, the correct option is (C).
During the sequence of conditioning, as the stimulus is delayed, dogs often display anticipatory anxiety or excitement. This phenomenon is known as the "anticipatory response" and is a form of classical conditioning. The dogs have learned to associate the delayed stimulus (e.g., the sound of a bell) with the upcoming reward or punishment. As a result, they exhibit a conditioned response, expressing their anticipation of the outcome even before the actual stimulus is presented.This anticipatory response is a crucial aspect of classical conditioning, demonstrating the learned association between the conditioned stimulus (the bell) and the unconditioned stimulus (the reward or punishment). It reflects the dog's ability to predict the forthcoming event based on their prior experiences and conditioning history.Therefore, the correct option is (C).
