Self-awareness can be demonstrated by both humans and animals if they:.
Answer:
Appear to be aware of life and death, understand it, and can understand the effects of their actions.
Explanation:
Most animals are aware that they will die, however certain animals, such as elephants, seem to be more aware of the permanence of death, resorting to violence towards other animals typically only when absolutely necessary. The understanding of the effects of their actions is often seen through caring for young and ending fights before a death occurs, which is often seen in big cat species, where, when fighting for dominance, makes will often roll over to signify forfeit.

In which phase of mitosis do sister chromatids separate?.
Answer:
Anaphase II
Explanation:
"Anaphase II
As the proteins holding them together break down, the sister chromatids separate. These separating sister chromatids will be allocated into different cells. As the spindle fibers shorten, the separated sister chromatids move towards the ends, or poles, of the cell."

In plants and algae, _____ is the source of the electrons needed for photosynthesis.
In plants and algae, light energy is the source of the electrons needed for photosynthesis.
In plants and algae, water is the source of the electrons needed for photosynthesis, which is present in Option A, as in the light-dependent reactions of photosynthesis, water molecules are split and electrons move.
What is photosynthesis?Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy that occurs in the chloroplasts of plant and algal cells, and there are two main stages of photosynthesis: the light-dependent reactions and the light-independent reactions. Light energy is absorbed by chlorophyll pigments in light-dependent reactions, and water splits to release electrons, which then these electrons move through a series of enzyme and protein complexes to produce ATP and NADPH.
Hence, In plants and algae, water is the source of the electrons needed for photosynthesis, which is present in Option A.

Which catastrophic event does NOT have an earthquake as a possible trigger?
landslide
hurricane
tsunami
Hurricane is the catastrophic event which does NOT have an earthquake as a possible trigger.
What is a hurricane?A hurricane is a powerful and large tropical storm that forms over the Atlantic Ocean and northeastern Pacific Ocean. It is characterized by strong winds, heavy rainfall, and a large, spiraling circulation of clouds and winds. Hurricanes form from low-pressure systems that develop over warm ocean waters and can bring widespread damage to coastal areas and inland regions.
The term "hurricane" is used primarily in the Atlantic Ocean and northeastern Pacific Ocean, while similar storms in other parts of the world are known as typhoons or tropical cyclones, depending on the region. Hurricanes can cause severe damage to property, disrupt transportation and communication systems, and lead to widespread power outages. They can also lead to storm surges, which are large and dangerous increases in sea level along the coast, and cause significant loss of life and property damage.

If you could merge two different animals to create the ultimate animal, what two animals would it be and what would be their product?
Answer:
I would do the Water Bear and the Wolf.
Explanation:
It would be almost invincible like the Water Bear, but a strong and fierce hunter like the Wolf.
That would be a lion and a tiger to form a liger. This process is known as hybridization.
What is hybridization?When two individuals from different species and are genetically different breed together to form a different organism, then this process is called hybridization, and the new organism produced is known as a hybrid. They have the traits of both parents.
Through hybridization, sometimes new species are produced. Sometimes hybrid can boost diversity.
Liger is produced by a cross between a male lion and a female tiger. When a female lion and male tiger are bred together, then a tigon hybrid is produced. There are so many examples of hybridization in animals like mules, liger, tigon, zebroids, and hinny, etc. Liger is an ultimate hybrid. Hence, Liger is the correct option.

2)Explain the 3 components of DNA (Pentose Sugar, Phosphate, Nitrogenous Bases)
3)Explain the 2 types of Nitrogenous bases (Purines vs. Pyrimidines)
4)Explain Chargaff's rules for base -pairing
5)Identify what objects/colors you used for your DNA Model
(Ex Key A=Red T= Green etc.)
Phosphate group = toothpick end
6)Twist your model and explain how it is a helix
Answer:
DNA
DNADeoxyribonucleic 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⁻

(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.

The DNA molecule has a ladder-type structural organization. Each rung of this ladder represents
A) alternating phosphate and glucose molecules
B) a pair of nitrogenous bases
C) ribose molecules
D) a random organization of proteins and lipids
Answer:
B
Explanation:
If you see the image attached, the edges of this "ladder" is made up of the phosphate groups and the insides of nitrogenous base pairs (ATCG). That is why we call this a ladder, in which we have a phosphate backbone and nitrogenous base stairs or "rungs".
Answer choices C and D are not even close to the right answer. They have nothing to do with DNA. Just try and remember that base pairs A, T, C, and G go on the inside & each strand has a phosphate backbone (edges).
Hope this helps!
The DNA molecule has a ladder-type structural organization. Each rung of this ladder represents B) a pair of nitrogenous bases as it has nucleotide sequences.
If you spot the picture attached, the rims of this "ladder" is made from the phosphate agencies and the insides of nitrogenous base pairs (ATCG). That is why we name this a ladder, wherein we've got a phosphate spine and nitrogenous base stairs or "rungs".
