Children less than approximately 2 years of age do not mount an adequate immune response to t-cell independent immunity.
The immune system in humans begins to develop during early pregnancy. Although the human foetus has the ability to respond with foreign antigens during midgestation, exposure is extremely restricted, and the immune system is generally described as naive at birth. Body’s immune system in the newborn includes B & T cell responses, which are not comparable to those seen in later children.
B cell responses towards T cell-independent antigens, including such polysaccharide antigens, are weaker in infants than in adults. Thus, pure polysaccharides do not elicit an effective antibody response in infants under the age of two. However, whenever these polysaccharides were conjugated (linked) to protein antigens, these become T cell-dependent and generate protective antibody responses in newborns as young as six months old.
The potency of such vaccinations is due to the significant maturation of T cell or T cell-dependent B cell responses, as well as the broad repertoire of antigens recognized by T cell or B cell receptors in the human child.

What is the difference between principle of overload and principle of progression?
Overload is the amount of load or resistance that places a larger stress, or load, on the body than it is used to in order to improve fitness, whereas progression is the method by which an individual should increase the load.
The progression principle states that when your body adjusts to your exercise programme, you must challenge yourself in order to continue experiencing growth. That challenge might be anything from increasing your time, intensity, weight, sets, reps, or anything else.
The second key factor is overload, which means that in order to improve any aspect of physical fitness, the individual must continually increase the demands placed on the corresponding biological systems. Heavier objects, for example, must be raised gradually to increase strength.
The development of a training variable simply involves making training increasingly difficult in some sense, but not always heavy. Progressive overload is a product of prior training in which performance improves as fitness improves.

Decerebrate posturing and loss of corneal reflex
Decerebrate posturing and loss of corneal reflex would be considered late signs of increasing ICP.
Growing pressure inside your skull might be caused by a brain injury or another medical problem. Increased intracranial pressure (ICP) is a serious condition that can cause a headache. The pressure might potentially cause more damage to your brain or spinal cord.
Changes in ICP are related to volume changes in one or more of the cranium's components. CSF pressure has been shown to be influenced by abrupt changes in intrathoracic pressure during coughing (which is induced by diaphragmatic and abdominal wall muscle contraction, the latter of which also increases intra-abdominal pressure), the valsalva manoeuvre, and communication with the vasculature (venous and arterial systems).

What are the 3 types of gene mutations explain each?
The three types of gene mutations are point mutations, insertion/deletion mutations, and chromosomal mutations.
There are several types of gene mutations, but the three most common types are:
Point mutations: Point mutations involve the alteration of a single base pair in the DNA sequence. This can result in a change in the amino acid sequence of the protein encoded by the gene, which can have a range of effects depending on the location and nature of the change. Some point mutations may have no effect on the protein's function, while others can cause the protein to be non-functional or to have altered function.Insertion/deletion mutations: These mutations occur when one or more base pairs are added or removed from the DNA sequence. This can disrupt the reading frame of the gene, leading to a frameshift mutation that drastically alters the amino acid sequence of the encoded protein.Chromosomal mutations: Chromosomal mutations involve changes to the structure or number of chromosomes. Examples include deletion of a segment of a chromosome, duplication of a segment of a chromosome, translocation of a segment of a chromosome to a non-homologous chromosome, or inversion of a segment of a chromosome. These mutations can alter the expression or function of multiple genes at once and can have severe effects on the organism.To learn more about gene mutations at

Is BMI an accurate measure of health?
Answer:
Body Mass Index (BMI) is a measure of body fat based on an individual's weight and height. It is widely used as an indicator of overall health, but it has its limitations and criticisms in assessing someone's health status.
Explanation:
Body Mass Index (BMI) is a measure of body fat based on an individual's weight and height. It is widely used as an indicator of overall health, but it has its limitations and criticisms in assessing someone's health status.
One of the main criticisms of using BMI as an indicator of health is that it does not take into account an individual's muscle mass, which is denser than fat and can cause a higher BMI reading for athletes or individuals with high muscle mass. This means that someone who is physically fit and has a high muscle mass could be classified as overweight or obese based on their BMI, even though they have a healthy body composition.
Additionally, it does not distinguish between body fat and muscle, which is important because muscle weighs more than fat. So, an individual who is very muscular and lean may be classified as overweight or obese based on their BMI, even though they are actually in good health.
Another limitation of using BMI is that it does not consider an individual's overall health status. A person with a healthy BMI may still have high levels of body fat, heart disease, diabetes, or other health problems. Similarly, an individual with a BMI in the overweight or obese range may still have a healthy body composition and a low risk of health problems.
In conclusion, BMI can be a useful tool for identifying individuals who are at risk for certain health problems, but it should not be used in isolation to assess someone's overall health status. It is important to consider other factors such as body composition, muscle mass, and overall health markers when assessing an individual's health. A more comprehensive approach that includes evaluating body composition, diet, exercise and other medical markers such as blood pressure, cholesterol, glucose and insulin resistance may give a more accurate picture of someone's health status.

What do you call to the adaptations of exercise in the heat and allow the body to better cope with heat stress?
Acclimatization refers to the advantageous physiological changes that emerge as a result of frequent exposure to a hot environment. Increased sweating efficiency, earlier beginning of sweating, increased sweat output, and decreased electrolyte loss in sweat are examples of these physiological adaptations.
Heat acclimatisation is an increase in heat tolerance caused by progressively increasing the intensity or length of work done in a hot environment. The easiest strategy to acclimatise to heat is to progressively increase the effort done in a hot atmosphere over a duration of 1-2 weeks.
Increased perspiration, improved skin blood flow, lower body temperatures, less cardiovascular strain, better fluid balance, changed metabolism, and greater cellular protection are among the changes. Acclimation is the synchronized phenotypic response of an animal to a single stressor in the environment, whereas acclimatisation is the coordinated response to several distinct stressors at the same time (e.g., temperature, humidity, and photoperiod).
