Which factors are typically used to determine the range of healthy body weight? pulse divided by waist girth
ratio of waist to hips
ratio of height to weight
skinfold measurements
A range of healthy body weight relies on a variety of factors including the ratio of height to weight (BMI), skinfold measurements (body fat percentage), and ratio of waist to hips (fat distribution measurement).
Explanation:The factors typically used to determine the range of a healthy body weight include the ratio of height to weight, skinfold measurements, and the ratio of waist to hips.
The ratio of height to weight is also known as Body Mass Index (BMI). It is a useful measure to check if your weight is in a healthy range for your height. This is calculated by dividing your weight in kilograms by the square of your height in meters.
Skinfold measurements are taken to measure body fat percentage. Fat is pinched and measured using calipers at various parts of the body, and a formula is used to calculate body fat percentage.
The ratio of waist to hips or waist-hip ratio (WHR) is a measurement of fat distribution. It helps to identify if more fats are stored around your waist or hips, which could raise your risk for some health problems.

Which of the following forces always exists between any two objects having mass?
A. Elastic Force
B. Contact Force
C. Gravitational Force
D. Magnetic Force
C
Gravity is an intrinsic property of matter. The higher the mass of an object the bigger the gravitational pull it has. Even small particles like protons and neutrons have gravitation force but is almost negligible because of the minute mass of the nuclear particles.
Explanation:
It is believed that gravity of created from the warping of space-time continuum by any object with mass.
Distance between two masses also affects the gravitational force between the two bodies and the force can be calculated by the formulae;
F = G * (M₁ – M₂) / r²
Whereby;
F = Gravitational force
Where G = Gravitational constant
M₁ = mass 1
M₂ = mass 2

Two processes form a cycle when the output from one process is the input for the other process, and vice-versa. Explain why respiration and photosynthesis form a cycle. Refer to specific types of molecules in your answer.
Explanation:
Photosynthesis produces glucose and O2 from inorganic CO2, light energy and water.
6CO2 + 6H20 + (energy) → C6H12O6 + 6O2
These end products, namely O2 and glucose are then used in respiration...
C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≈38 ATP
The CO2 and H2O produced as waste in respiration can then be incorporated at the beginning of photosynthesis. Thus the reactions are cyclic- they feed into each other.
Further Explanation:
Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and carbon dioxide while oxygen is released. This occurs in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. This occurs in the thykaloids, where pigment molecules like chlorophyll reside.
Occuring in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II.
Additionally,
water (H2O) split by light during photolysis into H+ and OH- acts as a source of oxygen along with functioning as a reducing agent; it reduces the molecule NADP to NADPH by providing H+ ions and produces molecules of the energy storage molecule ATP through an electron transport chain. This occurs in the thykaloids, where pigment molecules like chlorophyll reside. Later, in dark reactions, NADP and NADPH are used in the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules. These store energy in their bonds, which can be released in respiration in the mitochondria.In all eukaryotic cells mitochondria are small cellular organelles bound by membranes, these make most of the chemical energy required for powering the biochemical reactions within the cell. This chemical energy is stored within the molecule ATP which is produced. Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’s cycle via the oxidization of pyruvate( through the process of glycoysis). The electron transport chain, in which oxygen functions as the terminal electron acceptor occurs in both plants and animals.
Glycolysis: occurs in the cytoplasm 2 molecules of ATP are used to cleave glucose into 2 pyruvates, 4 ATP and 2 electron carrying NADH molecules. The Kreb's cycle: in the mitochondrial matrix- 6 molecules of CO2 are produced by combining oxygen and the carbon within pyruvate, 2 ATP oxygen molecules, 8 NADH and 2 FADH2. The electron transport chain, ETC: in the inner mitochondrial membrane, 34 ATP, electrons combine with H+ split from 10 NADH, 4 FADH2, renewing the number of electron acceptors and 3 oxygen; this forms 6 H2O, 10 NAD+, 4 FAD.Learn more about photosynthesis at brainly.com/question/4216541

9. A spaceship takes off in Houston, Texas headed for the planet Mars. List the four layers of
Earth's atmosphere through which it will move, in order beginning with the closest layer.
Answer:
Earth's atmosphere is divided into five main layers: the exosphere, the thermosphere, the mesosphere, the stratosphere and the troposphere.
Explanation:
A spaceship departing from Houston, Texas, to Mars will move through the troposphere, stratosphere, mesosphere, and thermosphere, in that order, before entering the exosphere and finally leaving Earth's atmosphere.
The spaceship launched from Houston, Texas, aiming for Mars will pass through four main layers of Earth's atmosphere. These layers are distinct in terms of their composition and physical properties as the spaceship ascends from the Earth's surface into space.
Troposphere: The first layer above the Earth's surface where weather phenomena occur, extending up to about 8 to 15 kilometers.Stratosphere: This layer is above the troposphere, reaching up to about 50 kilometers. It contains the ozone layer, which absorbs and scatters the solar ultraviolet radiation.Mesosphere: The third layer extends from the stratosphere up to about 80 kilometers. Here, the temperature decreases with height, and it's where meteors burn up upon entering Earth's atmosphere.Thermosphere: The fourth layer, starting from about 80 kilometers and extending into space. The temperature increases with height due to the absorption of highly energetic solar radiation.After exiting the thermosphere, the spaceship will transition through the exosphere, where the Earth's atmosphere merges into interplanetary space. Each layer presents unique challenges and phenomena as the spaceship ascends, providing a fascinating journey from the Earth to the cosmos.
The beaker in the diagram below has a selectively permeable membrane separating two solutions. Assume that both water and salt can pass freely through the membrane. When equilibrium is reached, will the fluid levels be the same as they are now? Explain.
Answer
The movement of water molecules across a selectively permeable membrane is known as osmosis. A substance that moves by passive transport tends to move away from the area where it is more concentrated. Diffusion and osmosis both regard the dispersion of particles. By definition, water is the only substance that undergoes osmosis.
hope that helps
When equilibrium is reached ; The Fluid level will be higher at solution A ( Side A )
Given that the solutions are separated by a selectively permeable membrane which allows only water and salt through it. and the solution in side A is a concentrated salt solution ( higher percentage of salt ( solute ) ) while the solution on side B is a dilute solution with a lesser percentage of salt and starch.
The salt and water from side B will move through the membrane into side A leading to the decrease in the fluid levels of Side B. This is because during osmosis the movement of water molecule is from a region of higher water concentration to a region of lower water concentration.
Hence we can conclude that When equilibrium is reached The Fluid level will be higher at solution A ( Side A ).

when are amino acids used instead of gluecose
Final answer:
Amino acids are used as an energy source instead of glucose in situations of carbohydrate and fat deficiency, such as fasting or starvation. They are converted into intermediates that enter the Krebs cycle for ATP production, but this can lead to muscle wasting and tissue damage if prolonged.
Explanation:
Amino acids are typically utilized for protein synthesis and other nitrogenous substances like nucleotides, rather than as a primary energy source. However, in situations where there is a deficiency of carbohydrates and fats, such as during fasting or starvation, amino acids can be mobilized as an alternative source of energy. This is because amino acids can be converted into metabolic intermediates that enter the Krebs cycle, leading to the production of ATP.
In normal conditions, glucose is the preferred energy source, and amino acids are reserved for growth and repair processes. Yet, during periods of prolonged fasting or insufficient caloric intake, the body can resort to breaking down proteins into amino acids for energy, which can lead to muscle wasting and tissue damage if persisted for extended periods. This shift happens because the body has no mechanism to store excess amino acids; they must either be used for protein synthesis or be catabolized for energy and excretion.

What is malaria?biology
Answer:
Malaria can be described as a disease which is caused by a parasitic organism. The Anopheles mosquito carries the parasite Plasmodium in it. When this mosquito bites a human being, the parasite gets transferred into the blood of the person causing malaria. Before entering the blood cells, the plasmodium travel to the liver where they get matured.
Malaria is a life-threatening disease which kills many humans each year, especially people living in underdeveloped countries.
Malaria is a zoonotic disease caused by Plasmodium parasites transmitted through Anopheles mosquito bites, leading to severe symptoms and sometimes death. Drug resistance has made treatment challenging in some regions, but prevention and prompt treatment can reduce mortality.
Malaria is an infectious zoonotic disease caused by protozoan parasites of the genus Plasmodium, which are transmitted to humans through the bite of an infected female Anopheles mosquito. The disease is characterized by symptoms such as cyclic high fevers, chills, flu-like symptoms, and severe anemia. There are different species of Plasmodium, but Plasmodium falciparum is the most deadly. The life cycle of the malaria parasite involves replication within the liver and destruction of erythrocytes (red blood cells), causing the observed symptoms. Malaria treatments vary geographically, owing to the evolution of drug resistance in some parts of the world.
Prevention of malaria includes methods such as mosquito netting and vector control to reduce mosquito populations and thereby interrupt the transmission cycle. Prompt and efficient treatment is crucial, and although Plasmodium falciparum malaria can have a low mortality rate when treated, it remains a significant cause of death, especially in the tropics.

How do the particles move in active transport?
In active transport particles move by making use of energy in the form of ATP.
Explanation:
Unlike in passive transport particles have to move against the concentration gradient in active transport. Thus particles require energy to do so and this energy is in the form of ATP. Osmosis and simple diffusion are examples of passive transport where substances move from a region of high concentration to a region of low concentration.
This movement is down the concentration gradient. In active transport particles move from a region of low concentration to a region of high concentration which is against the concentration gradient. Active transport is of two types.
In the first type called primary active transport energy is directly used in the form of ATP. In the second type called secondary active transport an electrochemical gradient created by ATP is used to facilitate the transport.

Answer:
Answer for third question.
Explanation:
The permanent destruction of forests to use the land or trees is known as deforestation. Deforestation takes place due to a number of reasons like natural causes and human activities. The main cause for deforestation is overpopulation. Overpopulation results in an increase in global needs which leads to expansion of infrastructures, industries, agricultural needs and thus deforestation. Other reasons for deforestation are infrastructure expansion , logging for wood based industries, farming, mining etc. Deforestation causes drastic changes in the environment. The environmental problems which results from widespread deforestation include climatic changes, loss of biodiversity, flooding, increase in greenhouse gas emission, acidic oceans, air and water pollution etc. Deforestation results in global warming. Planting trees reduce the effects of deforestation by preventing soil erosion and pollution. The other ways to lessen the effects of deforestation includes recycling and using of recycled products. Reduce the usage of paper and use wood alternatives like hemp, bamboo, wood composites etc for construction and remodeling products. Also we can raise awareness in the community against deforestation through campaigns

Hunter-gatherers:
Over hunting species leads to extinction (especially species like giant sloths, giant bison, mastodons, cave bears, saber-toothed cats)Agricultural Revolution:
Flora and Fauna became domesticated Habitats were destroyed because the grasslands forests and wetlands were replaced by farmland that results in erosion and floods and made the soil less fertileIndustrial revolution
Artificial substances replaced raw animals and plant products (plastics, pesticides) The rate of pollution increased.Final answer:
The hunter-gatherer lifestyle did not heavily impact the environment, whereas the Agricultural and Neolithic Revolutions led to changes in land use, social organization, and significant environmental manipulation. The Industrial Revolution further transformed human activity with mass production, causing notable increases in atmospheric CO2 levels.
Explanation:
Throughout history, the way humans have interacted with their environment has dramatically evolved. The hunter-gatherer societies had minimal impact on the environment as they fitted seamlessly into ecological food chains. However, the advent of the Agricultural Revolution around 3000 B.C.E. introduced permanent tools and farming tactics like crop rotation and the use of waste as fertilizer, paving the way for larger human settlements, trade, and increased environmental manipulation.
The Neolithic Revolution signified a pivotal shift from hunter-gatherer lifestyles to agriculture, leading to larger populations, specialization of labor, and sophisticated settlements such as Jericho and Çatalhöyük. This transition necessitated changes in land use, social organization, wealth accumulation, and even religious practices. However, not all societies embraced farming due to environmental unsuitability or perceived disadvantages.
The Industrial Revolution brought about significant changes in production, leading to widespread environmental impacts including an increase in global atmospheric carbon dioxide concentration. This remarkable era transformed human activity and initiated the mass manufacture of goods, which had global repercussions, shifting the world into a new ecological era.
