Answer:
The sun has an arrow leading to the decomposer, the sun should be at the bottom of the pyramid
Explanation:
The sun is the ultimate source of energy that provides energy to the producers. The producers use the light energy to synthesize the chemical compound. The energy from the producers is transferred to the primary consumers and their energy is transferred to the next levels. The sun cannot be decomposed by decomposer so the arrow from the sun leading towards the decomposer is not right.
Answer:
Relaxation of the dartos muscle.
Explanation:
Testes are present in scrotum outside the pelvic cavity to maintain the temperature about 2-3 degrees Celsius below the body temperature as required for sperm production. Dartos muscle is the layer of smooth muscle located in the superficial fascia. The contraction of dartos muscle serves to make the skin of the scrotum wrinkled and tight.
During hot weather, the dartos muscle relaxes and makes the surface of scrotum less wrinkled to increase the loss of the heat from its surface. The increased heat loss from the surface of scrotum due to relaxed dartos muscles keeps the testes protected from heat.
Answer:
Population distribution is the spreading of people over an area of land, while population density is the number of people per unit land.
Explanation:
The distribution of population is how people are distributed over an area of land and the population density indicates how densely populated an area is and it is often determined by the number of people per square mile.
Answer:
C.
The matter is converted to energy and carbon molecules.
Explanation:
Matter and energy cannot be created nor destroyed.
Matter can, however be degraded, melted, solidified, etc.
Eating something converts potential energy from the matter into chemical energy to power one's body, like the squirrel. The matter is not destroyed, however, and there are carbon molecules and other nutrients in the squirrel's body that are remnants of the acorn.
The <u>dermis</u> is a sturdy collagenous layer that connects the <u>epidermis</u> to the fatty tissue layer.
<h3>Living organisms </h3>
Living organisms; be it plants or animals are any organic or living system composed of cells and function as an individual entity.
All living organisms share a number of key characteristics or functions such as movement, respiration, homeostasis, reproduction, growth, evolution, competition and others.
Animals and plants also posess systems such as the digestive, skeletal, transport, nervous, excretory, respiratory and reproductive system.
Living organisms are also taxonomically classified as either unicellular microorganisms or multicellular plants and animals
So therefore, the dermis is a sturdy collagenous layer that connects the epidermis to the fatty tissue layer.
