Some invertebrates, after hatching from eggs, look completely different from their parents and are probably in a _____ form. larva pupa nymph embryo

Answers

Answer: Larva

Explanation:

  • The class of invertebrates in which the young one looks completely different from the adult form is known as holometabolous organisms.
  • In holometabolous organisms, the young one known as the larva is completely different from the adult and the process in which the larva transforms into an adult is known as metamorphosis.
  • For the process of metamorphosis, the following life stages occur,
  • Adult ---> egg---->larva--->pupa ---> adult
  • E.g is a butterfly in which the larva (caterpillar) looks completely different from the adult butterfly.

Answer:

Larva

Tropical areas receive the most solar radiation because A. the Sun's rays are nearly perpendicular to Earth's surface.
B. the air is thinner, causing more of the Sun's rays to reach the surface.
C. most tropical areas are situated at higher elevations, closer to the Sun.
D. they're surrounded by large bodies of water which reflect sunlight.

Answers

Answer;

A. the Sun's rays are nearly perpendicular to Earth's surface.

Explanation;

-Tropical region receives more solar radiation not only because the Sun’s rays hit the region more directly, but also because they travel through less of the atmosphere to get there.

-Some radiation is absorbed as it travels through the atmosphere, so less energy is lost in tropical regions.

Is D most tropical areas are situated at higher elevations, closer to the sun

An orange roughy fish is a fourth-level consumer that requires almost ten times the amount of food available from the primary producers in the ecosystem. Why isn't more energy available from the primary producers?A. Primary producers are not very efficient and lose most of their energy to the environment.
B. There is too much competition from other fourth-level consumers, leaving very little available to the orange roughy.
C. Only a fraction of energy is passed through each level, so there is less available to upper-level consumers.
D. The energy flow is unbalanced and tends to move toward the lower levels.

Answers

The correct answer is option C

The fraction of energy that is available to the fourth level of the ecosystem is very less because the fraction of energy is passed on through each level.

According to the law, only 90% of the energy is transferred through each tropic level and rest of the energy is lost in the form of heat.

Thus, only a fraction of energy reaches the upper tropic level starting from the producers.
C is the correct answer. Remember the 10% rule that only 10% of the energy is passed from one trophic level to the next. Hope this helps!
