The transport that is considered to be the opposite of diffusion because it moves molecules from an area of low concentration to an area of high concentration- against the concentration gradient is called active transport.

Active transport is a process that moves ions or molecules against their concentration gradient. It utilizes a protein carrier to move molecules across a membrane, like a pump. This is done with the help of enzymes, which are biological catalysts, that helps to facilitate the transport process. Examples of active transport include the sodium-potassium pump, which maintains the concentration of ions inside and outside of cells, and the endocytosis and exocytosis of molecules by cells.

Active transport requires energy, which is typically provided by the cell in the form of ATP, to move molecules across a membrane. This process is in contrast to diffusion, which is the movement of molecules from an area of high concentration to an area of low concentration, and does not require energy.

Answer:

choroid plexuses

Explanation:

The initiation of DNA synthesis begins with the production of a short RNA segment called a primer. Primers are short sequences of RNA nucleotides that are complementary to the template strand of DNA.

Primers are synthesized by an enzyme called primase, which uses the template strand of the DNA as a guide. These primers are then used as a starting point for the replication of the DNA. DNA polymerase, an enzyme that adds nucleotides to the primer, then binds to the primer and begins to synthesize the complementary strand of DNA.

The primers are then removed and replaced by DNA nucleotides. This process of primer synthesis and DNA replication is repeated until the entire DNA sequence is copied.

The statement "the krebs cycle is inhibited if the cell lacks oxygen" (option b) is true, because If there is no oxygen, the respiratory cycle cannot function, and the Krebs cycle is shut down.

The krebs cycle is powered by lipids (fats) and carbohydrates, which both produce the molecule acetyl coenzyme-A. (acetyl-CoA). This acetyl-CoA reacts in the first of eight steps of the Krebs cycle, which all take place inside the mitochondria of eukaryotic cells. While the Krebs cycle produces carbon dioxide, it does not directly produce significant chemical energy in the form of adenosine triphosphate (ATP), and this reaction sequence does not require any oxygen. Instead, this cycle generates NADH and FADH2, which feed into the respiratory cycle, which is also found inside the mitochondria.

To the thalamus of the brain are both general and most special senses carried.

The thalamus is a large mass of grey matter located in the dorsal portion of the diencephalon (a division of the forebrain). The thalamus releases nerve fibres in all directions that travel to the cerebral cortex, allowing for hub-like information exchanges.

Each thalamus is divided into roughly three main parts: the anterior, medial, and lateral thalamus, depending on where the internal medullary lamina is located.

The thalamus transmits sensory signals to the cerebral cortex from receptors located throughout the body. A sensory impulse that travels from the body's surface is received by the thalamus, which then interprets it as a sensation. After processing this sensation, the cerebral cortex interprets it as touch, pain, or temperature.

Cell growth phase where a cell increases in size, carries on metabolism, and duplicates chromosomes prior to division is known as interphase.

Divided into three stages: G1, S, and G2. During G1, the cell growth and carries out normal metabolic functions. In S phase, the cell replicates its chromosomes in preparation for cell division. In G2, the cell checks for any errors in replication before initiating cell division. Interphase is the period of the cell cycle during which a cell grows and replicates its DNA in preparation for cell division. During G1, the cell carries out normal metabolic functions, grows in size, and checks for any DNA damage. If the cell detects any damage, it can either repair the damage or initiate programmed cell death (apoptosis). In S phase, the cell replicates its DNA, doubling the number of chromosomes in preparation for cell division. This process is tightly regulated and controlled to ensure that each daughter cell receives a complete and accurate copy of the genetic material. In G2, the cell undergoes a final growth phase and checks for any errors that may have occurred during replication. If errors are detected, the cell may initiate apoptosis or delay cell division until the errors can be repaired. Once interphase is complete, the cell can enter the mitotic phase (M phase) and divide. Interphase is the longest phase of the cell cycle, taking up about 90% of the time, and it's the time when most of the cell's metabolic functions and growth occur.

The most likely explanation for the development of the new antibiotic-resistant strain of Escherichia coli is that it acquired the gentamicin-resistant gene from the Klebsiella pneumonia strain through horizontal gene transfer. This type of gene transfer is when genetic material is transferred between non-related organisms, allowing the recipient organism to gain new genetic traits. In this case, the E. coli strain likely acquired the gentamicin-resistant gene from the K. pneumonia, allowing it to become resistant to the antibiotic.
