Answer:
<u><em>All of the above.</em></u>
Explanation:
1. Their watertight skin minimizes moistures loss: <em>Reptiles have a reputation that they are “slimy” when we touch and hold them; however, they have dry skin, which has even fewer glands than mammals or amphibians. The main special feature of their skin is that the epidermis is heavily keratinized with a layer, which also prevents water loss.</em>
2. Amphibians must lay eggs in water or in moist soil to reduce moisture loss: <em>Because amphibian eggs don't have an amnion, the eggs would dry out if they were laid on the land, so amphibians lay their eggs in water.</em>
3. Reptile egg shells are harder than amphibians' eggs: <em>Reptile eggs are coated with a leathery or brittle coating, and the animals that hatch from them are miniature versions of the full-sized animal parent. In contrast, amphibian eggs are transparent and jelly-like. The animals that hatch from them still must go through metamorphosis.</em>

Answer:ways Water enters the atmosphere evaporation, transpiration, excretion and sublimation:
Explanation:
Transpiration is the loss of water from plants (via their leaves).
Sublimation is when ice or snow transforms directly into water vapour without going through a liquid phase (i.e. they do not melt).
Animals excrete water by respiration and by passing urine.
Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase.
Carbohydrate residues attached to the membrane lipids are always positioned on the extracellular side of the membrane
Carbohydrates are significant parts of the cell membrane, present just on the external surface of the plasma layer, and are appended to proteins, framing glycoproteins, or lipids, and framing glycolipids. These carbohydrate chains might comprise 2-60 monosaccharide units and can be either straight or branched.
The carbohydrates of the membrane are engaged with cell bond and acknowledgment and go about as a physical barrier. Enormous, uncharged particles, for example, glucose can't diffuse through the membrane.
These carbohydrates structure particular cell markers, that permit cells to perceive one another. These markers are vital in the resistant framework, permitting safe cells to separate between body cells, which they shouldn't assault, and unfamiliar cells or tissues, which they ought to.

significant digits are certain digits that give detail in a number
ex. in the number 400 it is the 4 because it tells you how many hundreds are in the number, in the number 49.92 it would be all of them because they all help understand the number
Do you get it?
The energy released is used for assembly of actin filament with myosin head. when myosin is attached to ATP its heads cannot bind to actin and therefore muscle will remain in relaxed form. However during muscle contraction an enzyme referred to as ATPase hydrolyses ATP to ADP and organic phosphate in the process releasing energy. The energy released changes the position of head of myosin which facilatate its binding with actin. Myosin moves towards m-line dragging actin along with it reducing the length of sarcomere leading to muscle contraction.
