The answer is that NA formed during replication is c) semi-conserved.  

This means that when DNA replicates, each new double-stranded DNA molecule consists of one original (parental) strand and one newly synthesized (daughter) strand. This process is known as semi-conservative replication.  

The parental DNA strands serve as templates for the synthesis of new complementary strands, ensuring that the genetic information is accurately passed on to the daughter molecules.

Semi-conservative replication was first demonstrated by Matthew Meselson and Franklin Stahl in 1958 through their famous experiment using isotope labeling. Their findings showed that DNA replication does not result in fully conserved or not conserved molecules, nor does it produce haploid DNA molecules.

During replication, the double helix of the DNA molecule unwinds, and the two parental strands separate, forming a replication fork. DNA polymerase then adds complementary nucleotides to each of the parental strands according to the base-pairing rules (adenine pairs with thymine, and cytosine pairs with guanine).

As a result, two new double-stranded DNA molecules are formed, each containing one original strand and one newly synthesized strand, demonstrating the semi-conservative nature of DNA replication.

Through the process of Facilitated diffusion, glucose in tubular cells leaves the basolateral membrane and enters the interstitial fluid. Here option D is the correct answer.

Glucose reabsorption in the kidneys occurs through a complex interplay of transport proteins and cellular processes. After glomerular filtration, glucose is present in the tubular fluid, and it needs to be reabsorbed to maintain normal blood glucose levels. The first step in this process is the transport of glucose across the luminal membrane of the tubular cells, which occurs through a sodium-glucose symporter (SGLT).

SGLT is a type of protein that couples the movement of glucose to the movement of sodium ions down their concentration gradient. This process is known as secondary active transport, as it uses the energy stored in the sodium gradient to drive the movement of glucose against its concentration gradient. Once glucose is inside the tubular cell, it needs to be transported out of the cell and into the interstitial fluid to enter the bloodstream.

This process occurs through facilitated diffusion, a type of passive transport that does not require energy input. Facilitated diffusion involves the movement of glucose through a protein channel, known as a glucose transporter (GLUT), down its concentration gradient. GLUT is located on the basolateral membrane of the tubular cells, and it transports glucose from the cytoplasm of the cell to the interstitial fluid surrounding the tubules.

Condensin proteins are primarily responsible for the coiling and condensation of chromosomes during cell division.

These proteins are involved in the organization and compaction of chromatin into distinct structures, known as chromosomes. Condensins form ring-like structures that encircle chromatin fibers, enabling them to be compacted into smaller and more condensed structures. The coiling process is facilitated by ATP hydrolysis, which generates the energy required for the condensin proteins to actively move along the chromatin fibers, forming chromatin loops and eventually compacted chromosomes. The proper function of condensin proteins is essential for proper chromosome segregation during cell division, as errors in chromosome condensation can lead to chromosome missegregation, chromosomal abnormalities, and ultimately, cell death.

The feedback loop that coordinates the response to changes in homeostasis involves a stimulus, a signal, and a response mediated by the nervous and endocrine systems

The maintenance of homeostasis in living organisms involves a complex interplay between different physiological systems that work together to detect and respond to changes in the internal and external environment. To coordinate a response, a feedback loop is established that involves three main components: a stimulus, a signal, and a response.

When a change in homeostasis occurs, a stimulus is detected by specialized cells or sensors located throughout the body. These sensors then send signals to the central nervous system or endocrine system, which acts as the control center for the feedback loop. The signals are transmitted via specialized molecules such as neurotransmitters or hormones.

Once the central nervous system or endocrine system receives the signal, it initiates a response to counteract the change in homeostasis. This response can be either through the nervous system, where the body rapidly responds to the stimulus via muscle contraction or relaxation, or through the endocrine system, where hormones are released to regulate the body's physiological processes over a longer period of time.

In a typical test cross, one of the organisms is homozygous recessive for both traits being studied, and the other organism is heterozygous for both traits. The resulting phenotypic ratios can reveal whether the genes for the two traits are linked or assorting independently.

However, if both organisms in the test cross are heterozygous for the traits being studied, it is impossible to determine whether the observed phenotypic ratios are due to independent assortment or linkage. This is because the heterozygotes could produce the same phenotypic ratios as a dihybrid cross with independent assortment, even if the genes are linked.

To determine whether two genes are linked, a dihybrid cross between two organisms that are homozygous for the two traits is needed. The resulting phenotypic ratios can then be compared to the expected ratios based on independent assortment.
