Blood cells are produced in which system?a. circulatory system
b. immune system
c. skeletal system
d. endocrine system

Answers

Answer 1
Answer:


Correct answer is c  - Blood cell are produced in the skeletal system.

Red blood cells are produced on a regular basis in the bone marrow. Bone marrow is a red spongy material found within the cavities of many of the large bones of the body.

Red blood cell start as immature cell in the bone marrow and after about seven days of maturation, they are released into the bloodstream, that is, the circulatory system where they circulate for about 120 days before being replaced with new ones.

Answer 2
Answer: yes the correct answere is c skeletal system

Answers

1. D dripstone produced by buildup of minerals precipitated from groundwater. Water drips down from, for example, the roof of a cave and slowly leaves behind mineral deposits which form a shape similar to an icicle
  2. D running water cuts small channels into a slope Rill erosion is formed by soil removal from small streams of running water. They form based on how the water falls down a slope and tend to migrate to already depressed or softer areas of soil.

A student investigated how the pressure in a diving pool varied with depth. He filled a balloon with helium and tied it to the end of a long pole. Then he submerged the
balloon to various depths and observed the result. Which one of the following best
describes what happed to the balloon as it went deeper?

(a) The balloon got larger because the pressure of the water around it increased
compared with the pressure inside the balloon.
(b) The balloon got larger because the pressure of the water around it decreased
compared with the pressure inside the balloon.
(c) The balloon got smaller because the pressure of the water around it increased
compared with the pressure inside the balloon.
(d) The balloon got smaller because the pressure of the water around it decreased
compared with the pressure inside the balloon.

Answers

The balloon got smaller because the pressure of the water around it increased compared with the pressure inside the balloon. Therefore, the correct answer is (C).

As the student submerged the balloon to various depths, the pressure of the water around the balloon increased, which caused the balloon to get smaller. This is because the pressure inside the balloon remained constant, while the pressure outside increased.

The helium inside the balloon would have been compressed by the increased pressure of the water, causing the balloon to decrease in size. This phenomenon can be explained by Boyle's law, which states that the volume of a gas is inversely proportional to the pressure of its surroundings.

Answer: The question is not complete, options are not given but here are the options from another websites.

a. sexual reproduction.

b. binary fission.

c. parthenogenesis.

d. budding.

The correct option is C.

Parthenogenesis.

Explanation:

lizards undergo a process in which their unfertilized eggs can develop into new individuals and the process is called parthenogenesis because parthenogenesis is a reproductive strategy that involves the reproduction of new organisms without undergoing fertilization or the production of new organisms from unfertilized eggs and these can be as a result of the lizard not able to undergo sexual reproduction which can be as a result of environmental factors. This process does not involve sexual reproduction.
