Which of the following descriptions is MOST plausible for an ancestor of bats? An animal with-
A: two limbs and webbed toes.
B: a long tail that ate insects and lived in forests.
C: four limbs and a membrane consistent with gliding.
D: four fins that glided through the water.
Answer:
C
Explanation:
Four limbs and a membrane consistent with gliding are the structures found in ancestors of bats. Therefore, option (C) is correct
What is patagium?A membrane called the patagium helps animals glide or fly. Bats, birds, dromaeosaurs, pterosaurs, gliding mammals, flying lizards, and flying frogs have the structure. The uropatagium (particularly in bats) or interfemoral membrane connects an animal's hind limbs.
Bats' wing skin extends from the abdomen to the tip of each digit, connecting the forelimb to the body. Bat patagiums have four parts:
Propatagium: neck-to-first-digit patagium.Dactylopatagium: digits.Plagiopatagium: between final digit and hindlimbs.Uropatagium: posterior flap between hindlimbs.Therefore, option (C) is correct.

Earth's core is the source of the energy that drives the movement of tectonic plates. Which two processes help transfer this energy outward to earth's crust?
Answer:The two processes are CONDUCTION and CONVECTION
Explanation:
The Energy produced in the Earth core is generated by Sun, gravitational force , radioactive decay, and the Earth' rotation, To maintain balance in the earth, The processes of CONDUCTION and CONVECTION transfer energy (HEAT) to Earth's interior, which also helps the movement of tectonic plates at a constant rate.
Now, inside the earth mantle is made up of hot solid rock and because Conduction occurs more in solids, Its currents helps the continuous transfer of heat energy from the warmer mantle at the bottom to the cooler mantle at the top While Convection currents in the core move thermal energy causing the rising and sinking of warm and cooler molten rock inside Earth, thereby maintaining the motion of tectonic plates and creating a balance in the earth.
Answer:
Conduction and Convection

Explain how humans are able to produce one type of hemoglobin as they develop in utero, then produce another to use after birth
Answer:
Hemoglobin F has a different composition from the adult forms of hemoglobin, which allows it to bind (or attach to) oxygen more strongly. This way, the developing fetus is able to retrieve oxygen from the mother's bloodstream, which occurs through the placenta found in the mother's uterus.

The rate at which blood flows through the human body can change in response to multiple factors. Which statement describes one of these factors and the effect it has on blood flow?
A. The narrowing of blood vessels increases pressure and leads to faster blood flow
B. High blood viscosity increases the resistance in the blood vessels and leads to faster blood flow.
C. Low blood pH decreases the rate of diffusion through the blood vessels and leads to slower blood flow.
D. The changing of the shape of red blood cells to a crescent shape decreases resistance and leads to faster blood flow.
Explain why this is the correct answer and why the other ones are wrong:
Answer:
B
viscosity of blood causes an increased resistance in the blood vessels and
leads to slow blood flow
Explanation:
Viscosity refers to the thickness of blood. This thickness is caused by the number of red
blood cells. Thick blood travels through blood vessels at a slower rate than thin blood
