What human body response help maintain homeostasis?

Answers

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.

What 4 things do both eukaryotic and prokaryotes cells contain?

Answers

Answer:

Both prokaryotic and eukaryotic cells have structures in common. All cells have a plasma membrane, ribosomes, cytoplasm, and DNA. The plasma membrane, or cell membrane, is the phospholipid layer that surrounds the cell and protects it from the outside environment.

Explanation:

The similarities between the eukaryotic and prokaryotic cells are:

Cell membraneRibosomesDeoxyribonucleic acid (DNA)Cell wall

Eukaryotic cells are those cells that contains organelles that are membrane-bound. These cells are found in plants, animals, fungi, and protists.

Prokaryotic cells are those cells that does not contain membrane-bound organelles. The cell structure is simple with no definite nucleus.

There are four components that can be found in both the eukaryotic and prokaryotic cells. They include:

Cell membrane: This is a semi-peameable membrane that surrounds the cell.Ribosomes: They are structures that are specialized for protein synthesis.Deoxyribonucleic acid (DNA): This is a hereditary material.Cell wall: This contains cellulose that helps protect the cell.

Answers

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.

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.

Answers

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.

Radiometric dating calculates an age in years for geologic materials by measuring the presence of a short-life radioactive element, e.g., carbon-14, or a long-life radioactive element plus its decay product, e.g., potassium-14/argon-40. The term applies to all methods of age determination based on nuclear decay of naturally occurring radioactive isotopes. Bates and Jackson (1984)

Given the DNA sequence 3'TACCGAGGCATT 5' what is the complementary strand sequence?

Answers

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.

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.
