The correct terms or tissues are :

mesenchyme

chondrocytes

fibrocartilage

stratified epithelia

reticular connective tissue

Explanation:

1. Mesenchyme is comprised of loose cells embedded in a mesh of proteins and fluid that makes the middle portion of the unspecialized mesoderm from which cartilage, bone, and blood develop.

2. The mature cells that live in cartilage and maintain the matrix around them are chondrocytes.

3. Fibrocartilage is a type of cartilage with a net of collagen fibers to help resist compression and tension.

4. Any tissues that exist in layers and form linings or coverings fall into the category of stratified epithelia.

5.. Reticular connective tissue is the type of connective tissue that is a supportive structural network fibre to support other cells.

Protein synthesis, the process by which cells generate proteins, differs in prokaryotes and eukaryotes due to several factors related to their cellular structures and mechanisms. Prokaryotes, such as bacteria, lack a distinct nucleus and other membrane-bound organelles, while eukaryotes, including plants, animals, and fungi, have a well-defined nucleus and various organelles. This difference affects the localization and regulation of protein synthesis. In prokaryotes, transcription (the synthesis of RNA from DNA) and translation (the synthesis of proteins from RNA) are coupled, meaning they occur simultaneously. The mRNA transcript is rapidly translated into protein by ribosomes as it is being synthesized. In contrast, eukaryotes separate transcription and translation in time and space. Transcription occurs inside the nucleus, and the mRNA is then processed, modified, and transported to the cytoplasm, where translation takes place. Eukaryotic mRNA undergoes various modifications before it can be translated into protein. This includes the addition of a 5' cap and a poly(A) tail, as well as the removal of introns through a process called splicing. These modifications provide stability, facilitate transport to the cytoplasm, and allow for the production of multiple protein isoforms. Prokaryotes do not typically undergo extensive mRNA processing. Prokaryotic and eukaryotic ribosomes differ in size and composition. Prokaryotes have smaller ribosomes (70S) composed of a 30S and a 50S subunit, while eukaryotes have larger ribosomes (80S) consisting of a 40S and a 60S subunit. These structural differences impact the initiation, elongation, and termination of protein synthesis. Eukaryotes possess more complex mechanisms for regulating gene expression compared to prokaryotes. Eukaryotic gene expression is regulated at multiple levels, including transcriptional control, post-transcriptional modifications, and translational control. This allows for fine-tuning of protein synthesis in response to various internal and external signals. Prokaryotes primarily regulate gene expression at the transcriptional level.

Overall, the differences in protein synthesis between prokaryotes and eukaryotes are rooted in their distinct cellular organization, mechanisms of gene expression, and the need for eukaryotes to coordinate protein synthesis within a more complex and compartmentalized cellular environment.

The type of replication error that would be most likely to result in genetic variation among organisms is a mutation.

Mutations are changes in the DNA sequence that occur during the replication process. They can introduce new genetic variations by altering the sequence of nucleotides in the DNA. Mutations can be caused by various factors, including errors in DNA replication, exposure to mutagenic agents (such as radiation or certain chemicals), or spontaneous changes in the DNA structure.

When a mutation occurs in the DNA of an organism, it can lead to changes in the genetic information. These changes can be beneficial, detrimental, or have no significant effect on the organism's phenotype. However, if a mutation provides a survival advantage or increases an organism's reproductive success, it may be selected for and passed on to future generations, resulting in genetic variation.

The occurrence of mutations is a natural and ongoing process in the evolution of organisms. It contributes to genetic diversity, allowing populations to adapt and respond to changes in their environment over time. Therefore, mutations are the primary replication error that leads to genetic variation among organisms.

Gluconeogenesis is a metabolic pathway that synthesizes glucose from non-carbohydrate sources, such as proteins and fats, to maintain a steady level of glucose in the bloodstream.

While the body is in a postabsorptive condition, it is fasting and unable to access any food sources of energy. To achieve its energy requirements during this period, the body must draw on reserves of glycogen, fat, and protein. Usually, this condition develops 8 to 12 hours after breaking the fast.

The process of gluconeogenesis is primarily responsible for the postabsorptive state's blood glucose synthesis. A metabolic mechanism called gluconeogenesis produces glucose from non-carbohydrate sources including proteins and lipids in order to keep the blood sugar level stable. This procedure results in the creation of glucose, which is then released into the circulation, from molecules including lactate, glycerol, and certain amino acids. This is crucial because it aids in controlling blood sugar levels and keeps them from dropping too low.

Answer:A) Patau Syndrome (Trisomy 13) causes intellectual and physical disability, such as underdeveloped eyes, extra fingers/toes, heart defects. Survival beyond the first year is uncommon.

B)

Explanation: Trisomy (or aneuploidy in general) can result when chromosomes to do not separate correctly during mitosis or meiosis. In meiosis, non-separation of a chromosome pair results in a gamete with two copies of the chromosome (and consequently one gamete lacking the chromosome.

At fertilisation the embryonic cell will have three copies of the chromosome (and an embryonic cell with one copy only). These are serious mutations, many of which are non-viable and usually abort spontaneously. Others results in abnormal development and poor survival rates. Only one autosomal trisomy (21) and sex chromosome trisomies (XXX, XXY etc) result in babies that survive into adulthood, albeit with physical and developmental abnormalities (trisomy 21 abd trisomy X). Only one monosomy (XO) is viable.

Other mutations can be less inimical, and may not result in any variation from normal. Mutations in genes coding for proteins or ribosomes may result in potential loss of function. As there are two copies of each gene, the mutated gene is paired with a normal gene and if that is expressed there will be no loss of function.

There are cases where the mutated gene is dominant it will change the phenotype. An example is Marfan Syndrome, an autosomal (chromosome 15) dominant mutation resulting in connective tissue abnormalities and long bones.

An autosomal recessive mutation is not expressed but is carried. If both parents are carriers, the probability of offspring to be doubly recessive and have an altered phenotype is 25%. Cystic fibrosis is an example.

A third possibility is where two alleles are co-dominant. An example of this is sickle cell disease. Consider the three allele pairs SS, Ss and ss.

Those with ss have sickle cell anaemia, a painful and debilitating condition. Those with SS have normal blood cells. Those with Ss have sickle cell trait, which has some mild deficits because a proportion of blood cells are abnormal.

Answer:

The benefits of being able to regulate the internal body temperature are many and it is considered a beneficial evolutionary character, since in this way the living organism is better maintained in relation to the environment, and it achieves better balance.

Reptiles cannot control their internal temperature, it depends on the external one, that is why to warm their body they need to be in the sun, and to cool down in the shade or in temperate places.

This is a little evolutionary characteristic since the environment is very changeable and the right or ideal temperature for the organism could not be controlled.

Explanation:

Faced with climatic catastrophes or extreme situations, living organisms cannot depend on the great climatic variants, in very cold situations one enters hypothermia and in very hot conditions the proteins are systematically denatured, entering a thermal shock.

Positive feedback loop increases the response whereas a negative feedback loop decreases the response.

Positive feedback is the amplification of a body's response to a stimulus. For example, in childbirth, when the head of the fetus pushes up against the cervix (1) it stimulates a nerve impulse from the cervix to the brain (2).

A feedback mechanism resulting in the inhibition or the slowing down of a process.

Examples of processes that utilise negative feedback loops include homeostatic systems, such as thermoregulation (if body temperature changes, mechanisms are induced to restore normal levels), blood sugar regulation (insulin lowers blood glucose when levels are high ,glucagon raises blood glucose when levels are low).

Answer:

A good answer could include planting the trees on the north-facing flank of a hill (passive) and providing overhead irrigation to allow the grower to give plants an ice coating (active). Apples grown in New York face their strongest threat during bloom-time. North-facing plantings partway up a hillside delays bloom-time to later in spring, reducing the odds of the plants experiencing a hard frost. Irrigation allows the grower to take advantage of the severe overall cold that can be associated with a freeze in upstate New York by using the cold to create a protective ice layer that can preserve the blossoms.
