Answer:  https://kidshealth.org/en/kids/blood.html

Red blood cells: Red blood cells (RBCs, also called erythrocytes; say: ih-RITH-ruh-sytes) are shaped like slightly indented, flattened disks. RBCs contain hemoglobin (say: HEE-muh-glow-bin), a protein that carries oxygen. Blood gets its bright red color when hemoglobin picks up oxygen in the lungs.

Why is it beneficial for an organism to have its tissues near its optimal temperature? List various functions or activities that
kykrilka [37]

Explanation:

Why is it beneficial for an organism to have its tissues near its optimal temperature? List various functions or activities that may be affected if the body temperature deviates too far from the temperature optimum (which functions or activities are mediated by proteins)?

a.) Muscle-movements

b.) Digestion of food

c.) Growth and development

Just about every aspect of an organisms daily functions are governed by the actions of proteins, be they structural proteins that determine cell shape, motor-protein that move vesicles inside the cell or allow muscle cells to contract, or be they enzymes that catalyze the vast majority of chemical reactions a cell has to engage in.

It turns out that every living organism gives off some heat. The difference between endotherms and ectotherms is merely the rate at which this heat is produced by the organism.

In fact, even plants and bacteria produce some heat as they go through their daily lives. This is evident in early spring, when the earliest spring flowers manage to thaw themselves through a solid ice layer, or when you overturn a compost heap on a crisp fall day in which bacteria decomposers are very active you will see steam rising from the pile.

What source have we already discussed that can produce this heat given off by organisms to their environment?

a) negative delta G of energetically coupled reactions.

Endotherms take advantage in particular of cellular respiration to ramp up that heat given off from energetically coupled reactions due to the Second Law of Thermodynamics.

As a consequence, endotherms maintain highly elevated rates of cellular respiration compared to ectotherms

b.) lowering of activation energy by an organism's enzymes

Describe the similarities you observe between the major stages in the life cycles of flowering plants and non-flowering, seed-be
irina1246 [14]

Answer:

<u><em>Seeds are found in both flowering and non-flowering plants. Both plants reproduce, the difference being that the former reproduces through blossoms, whereas the latter reproduces through seeds or spores. Because both flowering and non-flowering plants have chlorophyll, they can both photosynthesise.</em></u>

Why do you think there are earthquakes in mid-America where there are no known fault lines?
matrenka [14]
Earthquakes are mainly known to occur at plate boundaries where plates converge, diverge or slide past each other. Earthquake activity sometimes accompany volcanic eruptions but these too are concentrated around some plate boundaries (convergent, divergent). 

Smaller earthquakes are known to occur in intra-plate regions, away from margins. These occur simply because of stresses being built up in rocks. The crust is solid and rigid and it floats on the mantle which is a curved surface like the crust.
