Secondary structure proteins folding

Explanation:

Alpha helix and pleated sheets are basically two types if secondary structure of Proteins.

A fossil sample containing 2000 grams of k+ 40 in the beginning will contain 12.5 grams or potassium 40 during four half lifetimes, or 5200 million years.

The preserved remnants of organisms and plants that were submerged in sediments like sand and mud beneath ancient seas, lakes, and rivers are known as fossils. Any preserved sign of life that seems to be typically older than 10,000 years is considered a fossil.

Erosion, which is made up of tiny rocks, bury this. Sediment surrounding the skeleton accumulates as additional layers of sediment are added on top.

= 1.277 x 109 years.

So, 4 half lives = 4 x (1.277 x 109 )

= 5.108 x 109 years

molecule = (1/2)n x original molecule.

amount of potassium 40 ( K40) = (1/2)4 x 2000 g

= 2000/16

= 12.5 g.

Explanation:

Previously existing organisms leave behind evidences of their existence in form of remains that has been collected and mineralized called FOSSILS. However, the fossils of an organism (plant or animal) can either be a trace fossil or an original remain/body fossil. The difference between the two are as follows:

- An original remain is the fossilized body or body part of an organism that once existed. For example, bones, shells and fossilized leaf are examples of original remains.

- On the other hand, trace fossils refers to any form of evidence, apart from the organism's body, that suggests the presence of that organism in that particular place at a particular time. Trace fossils are said to be illustrate presence of life but indirectly (via their activities). Examples of trace fossils are burrows, tracks, marks etc.

Humans change ecosystems in many ways, such as habitat destruction, pollution, introduction of invasive species, and overexploitation of species.

The most common way that humans damage ecosystems is by destroying habitat. For example, we remove trees, change the flow of water, and change grasslands into farms. These practices can lead to local extinctions of species and cause other species to migrate to new areas.

pollen grains accurately summarizes a stage of the pine life cycle in which the apollen tube slowly helps in digestion its way through into the triploid endosperm.

Pollen grains are created by an anther and contain male gametes. In a procedure termed as fertilization, the male gamete and female gamete combine to create a zygote, which eventually develops into a new seed.

So the pollen is a male gametophyte that is either immature or partially formed. Similar to this, a unicellular microspore generates male gametes and undergoes mitotic cell division to become a mature microgametophyte. As a result, the pollen grains contain immature and made significant contributions male gametophytes.

LEVELS OF STRUCTURAL ORGANIZATION

------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The human body contains multiple levels of structural organization: chemical, cellular, tissue, organ, organ system and organism levels.

The simplest level of structural organization of living organisms is the chemical level. ATOMS of various elements combine to form larger, more complex structures termed MOLECULES. Organic molecules aggregate to form cellular ORGANELLES responsible for specific cell functions such as cell membranes, that regulate the movement of chemical substances into and out of the cell, mitochondria, that convert energy of organic nutrients into ATP, and ribosomes, that are involved in the production of protein molecules. (See notes on Chemical Composition of the Body.)  

CELLS are the structural and functional units of life. Each organism begins life as a single cell formed when a sperm injects the male genetic material (paternal chromosomes) into the ovum, forming a ZYGOTE, or fertilized ovum. Growth and development of a zygote through the stages of embryo, fetus, new born, child and adult requires two fundamental processes: mitosis and cellular differentiation. MITOSIS is a cell replication process - a type of cell xeroxing that results in an increase in the number of somatic cells in an organism. During mitosis, all the chromosomes and other cellular components in the parent cell are replicated so that each daughter cell receives a full set of 46 chromosomes and all essential cell components. Each somatic cell is formed from an existing cell by the process of MITOSIS. The process of CELLULAR DIFFERENTIATION allows cells, by SELECTIVE EXPRESSION OF GENES, to become anatomically distinct and functionally specialized. Although all cells contain 46 chromosomes and hence the complete human genome, cells generally only express about 15% of the genes they contain.

Cells of similar structure and function congregate to form TISSUES. There are 4 principle types of tissues in the human organism: epithelial tissue, connective tissue, muscular tissue and neural tissue. (See notes on Histology : Study of Tissues.)

Two or more types of tissues are combined within the same structure to form an ORGAN such as the heart, liver, kidney or brain. Most organs contain all 4 of the principle types of tissues.

Individual organs that function cooperatively to accomplish a common purpose are grouped together into ORGAN SYSTEMS. Examples include the cardiovascular system that functions to circulate the blood, the gastrointestinal system that functions to digest and absorb nutrients and the urinary system that removes metabolic wastes and excess minerals and water from the blood. There are eleven organ systems in the human body that are combined to form the complete human organism. See the text, pages 4-11 for the introduction to organ systems.

Answer:

cells, tissues, organs, organ systems, and whole organisms are the levels of cellular organizations.

Explanation:

(1) Two factors that influence cardiorespiratory fitness are age and physical activity level. Age plays a role in cardiorespiratory fitness as it affects the efficiency of the cardiovascular system and decreases maximum heart rate.

(2) A 30-minute aerobic workout initially fulfil the increased oxygen requirements of the muscles, the heart rate and stroke volume rise. Blood arteries enlarge in conjunction with this, improving blood supply to active muscles.

(3) The submaximal exercise test, which frequently employs the step test or treadmill test, is the most widely used technique for evaluating cardiorespiratory endurance.

(1) One of the elements that has a considerable impact on cardiorespiratory fitness is age. People's cardiovascular systems alter as they age, which may have an impact on how fit they are. With ageing, the cardiovascular system's effectiveness declines, which affects the body's capacity to provide working muscles with oxygen. Additionally, as people age, their maximal heart rates decrease, which reduces their total capacity for strenuous exercise.

By decreasing the body's capacity to satisfy the higher oxygen needs during physical exercise, these age-related alterations can have an impact on cardiorespiratory fitness. The quantity of exercise is a significant component that affects cardiorespiratory fitness. Regular physical activity and exercise promote cardiovascular system adaptations that raise fitness levels.

(2) The cardiovascular system alters in a number of ways during aerobic exercise, such a 30-minute workout. To initially fulfil the increased oxygen requirements of the muscles, the heart rate and stroke volume rise. Blood artery dilatation that results from this enhances blood supply to the working muscles. The heart becomes more proficient at pumping blood as the activity goes on, and the lungs take in more oxygen and expel more carbon dioxide. These modifications raise cardiorespiratory fitness and increase the overall effectiveness of the cardiovascular system.

(3) The submaximal exercise test, which frequently employs the step test or treadmill test, is the most widely used technique for evaluating cardiorespiratory endurance. These assessments are frequently utilised because they offer a useful and affordable technique to determine a person's level of fitness. In order to estimate cardiovascular fitness, they measure the heart rate response to exercise at submaximal intensities.

The maximum activity test, such as the graded exercise test or VO2 max test, is the most precise way for determining cardiorespiratory endurance. These tests calculate the maximum quantity of oxygen that a person can consume while engaging in strenuous exercise. While they offer a more accurate evaluation of fitness, they call for specialised equipment, experienced personnel, and may present higher hazards for people with particular medical issues.

False. Compared to aerobic respiration, anaerobic respiration generates more atp for muscular contraction, but it also produces lactic acid as a byproduct.

While producing less ATP, fermentation has the benefit of doing so relatively quickly. For instance, it enables your muscles to obtain the energy they require for brief periods of intense exercise. In contrast, the production of ATP during aerobic cellular respiration is slower. Compared to anaerobic respiration, aerobic respiration yields significantly more ATP. Compared to aerobic respiration, anaerobic respiration happens more quickly. The waste product created by anaerobic respiration is lactic acid. Lactic acid can accumulate in your muscles as a result of rapid running and cause cramps. The process of aerobic respiration, which needs oxygen, is the most effective one. The greatest amount of ATP is produced with this procedure.
