The evolutionary/cladistic scheme more accurately represents the similarities and differences between all members of the order Primates. The huge amount of anatomical and behavioral diversity seen in primates today is a result of various evolutionary forces operating over time.
This diversity reflects the adaptability and evolutionary success of the order, as different primates have occupied distinct ecological niches.
The traditional/gradistic scheme classifies organisms based on superficial similarities and hierarchies, often emphasizing subjective categorizations. On the other hand, the evolutionary/cladistic scheme is based on phylogenetic relationships and shared derived characteristics, providing a more accurate representation of evolutionary history. Since the order Primates encompasses a wide range of species with diverse anatomical and behavioral traits, the evolutionary/cladistic scheme is better suited to capture and explain the similarities and differences among them.
The huge amount of anatomical and behavioral diversity observed in primates today is a result of evolutionary forces such as natural selection, genetic drift, and gene flow. These forces act on the genetic variation within populations, leading to adaptations that enhance survival and reproductive success in specific ecological niches. Different primates have occupied distinct ecological niches, resulting in the evolution of specialized traits and behaviors. For example, primates living in arboreal habitats have adaptations for climbing and grasping, while those inhabiting open grasslands have adaptations for bipedal locomotion.
The adaptability and evolutionary success of the order Primates can be seen in their ability to thrive in various environments and exploit different food resources. This adaptability is reflected in their flexible behavior, cognitive abilities, and social systems. Primates exhibit a range of adaptations to selective pressures such as changes in climate, resource availability, predation, and competition. Traits like increased brain size, grasping hands, and complex social behaviors have allowed primates to occupy diverse niches and persist in different habitats.
In summary, the evolutionary/cladistic scheme accurately represents the similarities and differences among members of the order Primates. The remarkable anatomical and behavioral diversity seen in primates today is a product of evolutionary forces operating over time, reflecting their adaptability and evolutionary success in occupying distinct ecological niches.

Group of answer choices
sugar
nucleotides

amino acid
Answers
Amino acid is not a part of deoxyribonucleic acid (DNA).
DNA is composed of nucleotides, which consist of a sugar molecule, a phosphate group, and a nitrogenous base. The sugar in DNA is deoxyribose, which gives the molecule its name. The phosphate group links the sugars together to form a sugar-phosphate backbone, while the nitrogenous bases pair up to form the rungs of the DNA ladder. The four nitrogenous bases found in DNA are adenine, thymine, cytosine, and guanine. These bases pair up specifically: adenine with thymine and cytosine with guanine. The sequence of these base pairs forms the genetic code that determines the traits of an organism. Amino acids, on the other hand, are the building blocks of proteins and are not directly involved in DNA structure or function.

Multiple sclerosis (MS) involves an immune-mediated process in which an abnormal response of the body’s immune system is directed against the central nervous system (CNS) (i.e. the brain, spinal cord, and optic nerve). A hallmark of MS are lesions within CNS tissues that increase with volume over the lifetime of the patient or model animal. Mesenchymal stem cells (MSCs) have the ability to produce immunomodulatory factors that can alter the immune response in multiple tissues and are currently being investigated for their therapeutic efficacy in treating MS. In a mouse model of MS, a single MSC treatment can reduce the volume of MS lesions by 50% over the course of several months. Based on this study, researchers believe similar treatments can work in human patients.
You have been contracted to design a clincal trial for an MSC treatment of MS in partnership with the Mayo Clinic. Mayo has 2,558 patients under their care diagnosed with "mid stage MS" being treated with the current standard of care. The basis of diagnosing MS in these patients and monitoring disease progression is by imaging CNS lesions with MRI. Mid stage MS is defined as having a total lesion volume from 25-100 mm3 in the brain. In the proposed trial, patients will be given a single MSC infusion of 10M cells. Over the course of a year doctors will monitor lesion volume.

What examples show repair or replacement of damaged cells.
Answers
The examples provided, a, b, and c, all demonstrate different mechanisms of repair or replacement of damaged cells in the body.
a. A scrape being healed: When you experience a scrape or a minor injury, the body initiates a healing process. Specialized cells called platelets form a clot to stop bleeding, and immune cells migrate to the site of injury to clean it up and prevent infection. Fibroblasts then produce collagen, a protein that forms the framework for new tissue growth. New blood vessels, called capillaries, form to bring oxygen and nutrients to the healing area.
Over time, new skin cells, or epithelial cells, multiply and migrate to cover the wound, eventually closing it completely. This process is known as epithelialization and is an example of cell replacement.
b. Scars forming where a cut once belonged: In some cases, when the injury is deeper or more severe, the body's repair mechanism involves the formation of scar tissue. Scar tissue is composed of collagen fibers that help bridge the gap left by the injury.
While scar tissue is not identical to the original tissue, it provides a functional substitute, helping to restore the structural integrity of the damaged area. Scarring occurs when the body's healing response goes beyond the normal repair process and produces excess collagen.
c. Skin flaking off your arm in the winter: The shedding or flaking of skin is a natural process called desquamation. It involves the removal of dead skin cells from the outermost layer of the epidermis. Skin cells have a lifespan and constantly undergo a cycle of renewal.
New skin cells are generated at the bottom layer of the epidermis and gradually move upward as they mature. As they reach the surface, they become flattened, lose their nuclei, and eventually slough off. This shedding helps to remove old and damaged cells and allows for the replacement of fresh, healthy cells.
In summary, a scrape being healed involves the replacement of damaged cells through a series of processes, while scars forming indicate the formation of collagen-rich tissue to repair deeper injuries. Skin flaking off represents the natural shedding of dead skin cells and the continuous renewal of the epidermis.
These examples illustrate different ways in which the body repairs or replaces damaged cells to maintain its overall health and functionality.

why we are not aware of certain bodily processes such as growing hair
Answers
Because the autonomic nervous system regulates certain biological functions—such as hair growth—without our awareness, we are unaware of them.
This system regulates a variety of bodily functions, including breathing, digestion, heart rate, and hair growth and shedding. Reflex arcs control these processes in an unconscious manner in reaction to both internal and external inputs. The hair follicle, for instance, controls hair development by responding to hormonal cues and other cues to encourage hair growth or shed hair as necessary. The maintenance of homeostasis and the proper operation of our bodies depend on these processes, even though we may not be aware of them.For instance, we may simply be preoccupied with other thoughts and activities that distract us from noticing these processes. Furthermore, some bodily processes occur so gradually that they are difficult to perceive, especially when they occur over a long period of time.

Explanation:
A DNA molecule is a double-stranded molecule made up of nucleotide bases. There are four (4) nucleotide bases that make up the DNA viz: Adenine, Guanine, Cytosine, and Thymine.
According to Chargaff, who postulated the complementary base pairing rule that states that I the DNA molecule, Adenine base always hydrogen bond with Thymine base and Guanine base always hydrogen bond with Cytosine base i.e. A-T, G-C. Chargaff also found out that the amount of Pyrimidines (Cytosine and Thymine) are equal to one another, likewise the Purines(Adenine and Guanine).
According to Chargaff, the number of Adenine base equals the number of Thymine base that it pairs while the same occurs for Guanine and Cytosine pair. All bases total 1. Hence, the forensic scientists can assume that the number of Adenine base in the DNA is the same as the number of Thymine base.
