CELLS: Describe the structure of a eukaryotic plant cell. Indicate the ways in
which a non-photosynthetic prokaryotic cell would differ in structure from this
generalized eukaryotic plant cell.
Answer:
A cell that is nonphotosynthetic, such as a prokaryotic bacterium, would not require chloroplasts to function.Explanation:
A broad sweeping eukaryotic plant cell accomplishes the basic functions required for plant care. It's a jumble of organelles held together structurally by the cell membrane, which is located outside of the cell wall.
What is eukaryotic cell?Plant and animal cells are eukaryotic, which means they contain nuclei. Plants, animals, fungi, and protists all have eukaryotic cells.
They typically have a nucleus organelle surrounded by a membrane called the nuclear envelope, which stores DNA.
Prokaryotes are typically simpler, requiring only a few organelles to survive. This is frequently because, as previously stated, it requires less energy.
It has DNA to contain genetic material, ribosomes to make proteins, a cell membrane, and a cell wall to protect the cell from its surroundings. While other components are produced by prokaryotes, the ones listed above are those that may be found in plant cells.
Aside from that, the non-photosynthetic prokaryotic cell requires much less energy, resulting in a cell that is much smaller and less complex than the generalized eukaryotic cell.
Thus, this way, a non-photosynthetic prokaryotic cell would differ in structure from this generalized eukaryotic plant cell.

sion of existing cells?
Answer:
It would be the cell theory
Cell theory is the basic concept of biology includes the idea that new cells can be produced only by the division of existing cells.
What is cell theory?In biology, cell theory is a scientific theory first formulated in the mid-nineteenth century, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells.
A component of the cell theory is that all living things are composed of one or more cells. A component of the cell theory is that the cell is the basic unit of life. A component of the cell theory is that all new cells arise from existing cells.
All known living things are made up of cells. The cell is structural & functional unit of all living things. All cells come from pre-existing cells by division. (Spontaneous Generation does not occur).

II. Write a position statement on whether you think athletes like Santhi should be allowed to compete. Use evidence based reasoning in your position.
Answer:
The correct answer is stated in the Explanation section.
Explanation:
Santhi Soundarajan is an Indian track and field athlete that have won multiple international medals. Santhi was the center of a controversy when she was striped her silver medal after failing a sex verification test at the 2006 Asian Games. Santhi has a condition known as androgen insensitivity syndrome, she carries a Y chromosome althoug she has female genitalia. I think is not fair to disqualify an athlete like Santhi unless it is determined that she committed fraud and that she has an evident advantage. If Santhi knew her condition and it is established that she has an advantage after multiple tests, then her medal could be removed.

What human body response help maintain homeostasis?
Answer:
The endocrine system plays an important role in homeostasis because hormones regulate the activity of body cells. The release of hormones into the blood is controlled by a stimulus. For example, the stimulus either causes an increase or a decrease in the amount of hormone secreted.
Explanation:
Answer:
If a raise in body temperature (stimulus) is detected (receptor), a signal will cause the brain to maintain homeostasis (response). Once the body temperature returns to normal, negative feedback will cause the response to end. This sequence of stimulus-receptor-signal-response is used throughout the body to maintain homeostasis.

You are studying natural selection in a population of small marine invertebrates called isopods that live on pink corals. In this population, isopod body color is controlled by one gene with alternate alleles A and a. Isopods can be red (AA), pink (Aa), or white (aa); body size is controlled by another gene with alternate alleles B and b, and they can be large (BB or Bb) or small (bb). A new predator arrives on the reef that is extremely good at preying on isopods that are large and stand out against the corals on which they live (i.e., red or white individuals). Over time, which genetic individuals would you predict would become more abundant in the population with each subsequent generation?
Answer:
Aa, bb
Explanation:
Recall that this question calls our attention to the theory of evolution as postulated by Charles Darwin. Species that are well adapted to their environment are more likely to survive, reproduce and pass on these favourable characteristics to their offspring.
In this case, the coral reefs are pink and pink Isopod species with small bodies are likely to escape the predators. Hence the genetic combination Aa(pink body) and bb(small body) are more likely to survive and reproduce.
Which of the following best describes the formation of the bond shown in Figure 1 ?
А
An ionic bond is formed between a carbon atom of one amino acid and the nitrogen atom of the other amino acid,
B
An ionic bond is formed when the negative charge of an OH group is balanced by the positive charge of a hydrogen ion.
с
A covalent bond is formed between a carbon atom and a nitrogen atom along with the formation of H2O
D
A covalent bond is formed that replaces the hydrogen bond between the OH group and the H atom,
A covalent bond is formed between a carbon atom and a nitrogen atom along with the formation of H2O.
HOW PEPTIDE BOND FORMS:
Peptide bond is a bond that forms when two amino acids comes together. It involves the fusion of the amino group of one amino acid (NH2) and carboxyl group of another (COOH) with the release of water (H2O). Peptide bond is a type of covalent bond because it involves sharing of electrons between a carbon atom (C) and a nitrogen atom (N).Therefore, in the reaction shown in the image attached, a covalent bond is formed between a carbon atom and a nitrogen atom along with the formation of H2O.

Given the DNA sequence 3'TACCGAGGCATT 5' what is the complementary strand sequence?
Answer:
′UACCAAGGUAG5
Explanation:
DNA is a two-stranded molecule. Each strand is a polynucleotide composed of A (adenosine), T (thymidine), C (cytidine), and G (guanosine) residues polymerized by "dehydration" synthesis in linear chains with specific sequences. Each strand has polarity which runs from 5′ to 3′.
In DNA, A pirs with T and G pairs with C.
Fo through the original 5′ to 3′ sequence pairing each A with T ad each C wth G.
While RNA is a single strand molecule. This Strand also consists polynucleotide composed A, C, G and U (uridine).
For a complementary strand replace A with U (because RNA does not consist T), T with A, C with G, and G with C.
Hence,
Given strand: 5′ATGGTTCCATC3′
Complementary RNA strand: 3′UACCAAGGUAG5′
Keep in mind that the complementary strand will read from left to right in the 3 to 5 direction.

They have substances that counteract acids or bases to prevent the pH from changing.
Answer:
The correct answer is - They have substances that counteract acids or bases to prevent the pH from changing.
Explanation:
Including human, all the organism depends on the water so therefore known as waster system based which suggests that they depend on the acid-base liquid equilibrium to maintain its cellular functions and homeostasis.
Acid and bases are influences and determine the pH value of the chemistry of biological systems as every cycle is affected by the pH fluctuation so the maintenance of pH is very critical.
so as to keep biological system compound and in the equilibria of protonation, they have certain substances in each cycle or part that counteract the acid and base to maintain pH.

phosphate ion maintains the Cytoplasm pH
the bicarbonate ion regulates the Blood pH
