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.

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.

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.

Explanation:

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.

Explanation:

There are different form or type of blood group. These include blood group A, B, AB and O.

The blood group AB is usually known as the universal recipient while the blood group O is the universal donor.

A universal donor can donate blood to all other blood groups, while the Universal recipient can receive blood from all other blood groups.

In this case, two patients, one with blood group A and the other with blood group AB, with only one available group A type pint for transfusion. The best thing to do in this case is to give the blood to group A patient and get any other blood group pint of blood for the group AB patient. This is because the blood group AB patient can receive blood from any of the blood groups.

Explanation:

Answer:

D

Explanation:

The correct option here would be D.

The endomembrane system refers to a group of membrane-based organelles whose primary function is to synergistically work together to modify, package, and transport lipids and proteins. The system includes organelles such as the lysosome, the nuclear envelope, the endoplasmic reticulum, and the Golgi apparatus.

For an endomembrane system function involving a protein, the protein would first of all need to be synthesized by the ribosome - the free ones or the ones attached to the rough endoplasmic reticulum. Thereafter, the synthesized protein would then be folded or packaged into transportable vesicles. The vesicles are then received by the Golgi apparatus which further modifies the proteins before transporting them accordingly.

Hence, the correct order of a typical endomembrane system function would be:

Protein synthesis involves transcription and translation. Once the protein is synthesized, it suffers a few modifications in the RER and the Golgi complex, before leaving to its final destiny. The correct option is D. ⇒ 2, 3, 1, 5, 4

The first step before protein synthesis begins is to synthesize messenger RNA, mRNA.

This is the coping process of the DNA section for the desired protein, and it happens in the nucleus.

Translation takes place when the formed mRNA moves to the cytoplasm through the nucleus membrane pores, and meets a ribosome.

Ribosomes are organelles composed by the association of proteins with rRNA and tRNA. They can be found in the rough endoplasmic reticulum or floating in the cytosol.

While the ribosome reads mRNA strain from its 5´ extreme to 3´, tRNA adds the correct amino acids to build the polypeptide.

Some proteins are destined for membrane or exportation. Their synthesis starts in the cytoplasm but finishes in the Rough endoplasmic reticulum.

When the ribosome and the growing molecule reach the RER, the synthesizing protein keeps enlarging forward the reticulum lumen.

When the new polypeptide synthesis is complete, it is released into the reticulum lumen.

The endoplasmic reticulum is in charge of protein folding, maturation, and transport, especially those destined for secretion. It produces the latest protein modifications after transduction and initiates the glycosylation process.

The new proteins get packaged into vesicles that carry them to the Golgi complex.

Once the protein synthesis in the endoplasmic reticulum is over, these molecules are packaged into vesicles and sent to the Golgi complex.

In the Golgi complex, proteins suffer their final association with carbohydrates and lipids to originate glycoproteins and glycolipids.

Glycoproteins and glycolipids are packaged again into new vesicles that drive them to their final destiny.

Proteins destined for exportation are packaged and sent from the Golgi complex to the cell membrane into vesicles.

When the secretory vesicle reaches the target, its membrane fuses with the cell membrane, releasing its content to the extracellular space. This secreting process is known as exocytosis.

According to this resume about protein synthesis, we can say that the correct order is option D. ⇒ 2, 3, 1, 5, 4

2. Ribosomes on the RER synthesize proteins.

3. Proteins are packaged into transport vesicles.

1. Golgi apparatus receives transport vesicles from the RER.

5. Proteins are modified by the Golgi apparatus.

4. Modified proteins may be secreted from the cell by exocytosis.

′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.

Cell theory is the basic concept of biology includes the idea that new cells can be produced only by the division of existing cells.

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).

Answer:

a. countertransference

Answer:

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.

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.
