On the periodic table, you will see that they are grouped into different groups. Well, on the right, you have the groups, obviously. You are supposed to match the elements to the group that it is in.
(If you don't know the groups, you can find one online under images.) Hope this helps! Please give brainliest answer!
Which hormone is essential to our ability to maintain our fluid levels? Which hormone is essential to our ability to maintain our fluid levels? cortisol thyroxine insulin aldosterone
Aldosterone is a hormone that regulates the levels of sodium and potassium in our body, which leads to regulate our fluid levels.
In order to increase the fluids in our system, aldosterone causes the absorption of sodium from our kidneys. The kidneys are the place where our body filters the blood absorbing what it needs, such as sodium, and excreting the rest as urine. With the entering of sodium to our bloodstream, water also enters, increasing the volume of blood in our body.
Aldosterone is also responsible for the excretion of potassium into the urine, controlling the levels of this ion, which is extremely important for a high number of reactions.
Which of the following is a difference between food chains and food webs?Food webs contain both plants and animals, but food chains contain only plants.
Food webs separate organisms by trophic level, but food chains do not.
Food chains show energy flow in an ecosystem, and food webs do not.
Food chains are linear, while food webs are complex.
Option D, Food chains are linear, while food webs are complex.
A food chain is a linear organization in which the producer lies at the first stage followed by consumer organisms lying at primary, secondary and tertiary stages of food chain.
While in a food web, there can be several interlinked food chains or there can be an organism within the food web which is part of several food chains at an instance. Hence, the linearity of organization cannot be retained in case of food web thereby making it more complex than the food chain.
Hence, option D is correct.
Both food chains and food webs contain plants and animals so it is not A.
Food chains separate by trophic level not food webs so it is not B
***Food chains show energy flow by each trophic level and food webs do not therefore it is C***
Unlike amphibians, reptilesa. have lungs to oxygenate blood.B. use single-loop circulatory system.C. have a closed circulation system in which blood circulates entirely within blood vessels.D. have ventricles that are further divided to lessen mixing of oxygen-rich and oxygen-poor blood.
The answer is D. have ventricles that are further divided to lessen mixing of oxygen-rich and oxygen-poor blood.
Amphibian hearts have 3 chambers - one ventricle and two atria. Since there is only one ventricle, oxygenated and deoxygenated blood will mix. On the other hand, lizards have a septum in the ventricle. The septum divides ventricles resulting in less mixing of oxygen-rich and oxygen-poor blood.
How many days can the body survive without water? 2-3 5-6 8-10 10-12
The correct option is the first.
You can live without water for three to five days, nothing more.
When the organism begins to experience a notable decrease in water levels, an emergency system is activated with which the little that is still available in the body is optimized. As a result, the urine becomes darker and has a stronger smell and both the urge to urinate and salivation decrease. Then the cells begin to lose water, which travels to the blood, so they begin to contract. Finally, the organs begin to fail, usually beginning with the kidneys, which stop filtering the blood, with the accumulation of toxins that implies.
Human beings cannot store water, so we must replenish the water that is lost daily. Water is necessary for the proper functioning of our body, excretion of waste, evaporation of the lungs and skin.
A dry body cannot absorb or digest food. Bones are lost cushioning and become more prone to breakage, and infections. The body needs at least 8 glasses of water per day. This is to ensure that all cells and organs in the body are being adequately watered.
3 daysIn a harsh environment — it's snowing, say — you have 3 hours to survive without shelter. After 3 days, you need water or you'll perish. You can make it 3 weeks without food, though we promise you that won't be fun. Despite this possibly helpful rule, some people have survived 8 to 10 days without water.
