Explanation:
plants that are shorter and need little to no soil are most efficient. Lichens, which are part fungus and usually part algae, don't need extensive root or water-transportation system
Only about 10 percent
of the energy from each
level of an energy
pyramid is available to
the trophic level above
it. (The rest is used to
power life processes or
is lost as heat.)
If the primary producers
have 10,000 units of
stored energy, how
much energy would you
expect to be transfered
to first-level, second-
level, and third-level
consumers?
Answer:
First leve consumer: 1,000 energy units
Second level consumer: 100 energy units
Third level consumer: 10 energy units
Explanation:
First level consumer: 1,000 energy units. Second level consumer: 100 energy units. Third level consumer: 10 energy units.
What is trophic level?The group of species in an ecosystem that are at the same level in the food chain is referred to as a trophic level. A food chain has five basic trophic levels, each of which has a different nutritional relationship to the main energy source.
The Sun is any ecosystem's main source of energy (although there are exceptions in deep sea ecosystems). Primary producers, sometimes referred to as autotrophs, receive their energy input from the Sun's solar radiation.
The first trophic level is made up of primary producers. Consumers, also known as heterotrophs, make up the remaining trophic levels; heterotrophs are unable to reproduce.
Therefore, First level consumer: 1,000 energy units. Second level consumer: 100 energy units. Third level consumer: 10 energy units.

During replication, enzymes called ____________________ untwist the double helix, separating the two parental strands. The point at which the two chains separate is known as the _______________________.
Answer:
During replication, enzymes called helicases untwist the double helix, separating the two parental strands. The point at which the two chains separate is known as the replication fork.
Explanation:
Replication is the process of multiplication of DNA molecules where, from one molecule, two molecules with the same information as the original can be obtained.. Each new replicated DNA molecule has an original strand and a new strand, so replication is semi-conservative.
For replication to occur, the double strand of DNA must be separated, a process that requires the participation of a group of enzymes called helicases. The helicases are responsible for breaking the hydrogen bonds between the complementary bases of one strand and another.
The DNA strands, when separated, form a zipper-like image, and the point of separation between the two is called the replication fork.
The study of genes is called genetics.

speed = distance/ speed = 15 / 5 = 3 km/ sec .
How does earths rotation help to maintain its temperature? Please help!!!
Answer:
Earth returns an equal amount of energy back to space by reflecting some incoming light and by radiating heat (thermal infrared energy). Earth's average surface temperature is maintained by two large, opposing energy fluxes between the atmosphere and the ground (right)—the greenhouse effect.
13. What term do we use to describe the maintenance of constant conditions, such
as blood glucose levels, body temperature and water levels, inside the body?
A. Hormonal control
B. Nervous system
C. Homeostasis
D. Endocrinosis
Answer:
C. Homeostasis
Explanation:
"Homeostasis" refers to the process of maintaining the body's equilibrium. The body tries to adjust to different stimuli in order to help it function in normal ranges. For example, when a person is exposed to a cold weather all of a sudden, the person starts to shiver in order to maintain homeostasis. Shivering is a contraction of the muscles that allows the generation of heat.
On the contrary, when a person is exposed to the sun during summer, his body will start to sweat in order to maintain homeostasis. Sweating allows the heat to dissipate from the body thereby lowering the body's temperature.

How can scientists determine whether an extinct animal gave birth on land or under water?
Answer:
Location of the hind limbs of the fetus
Scientists can determine whether an extinct animal gave birth on land or under water can be determined by the position of the head of the fetus. Thus, the correct option is C.
What are Extinct animals?
An extinct animal is an animal which no longer exists. It is completely gone and can no longer be found on the planet Earth. It can be hard to tell exactly when a species, or a specific type of animal has become extinct in nature. Sometimes, scientists think that an animal has disappeared due to changes in the environment, only to find another living animal many years later.
Scientists can determine whether an extinct animal gave birth on land or under water on the basis of position of the head of the fetus.
Therefore, the correct option is C.

Food provides molecules that serve as fuel and building material for all organisms. Plants undergo photosynthesis and make their own food. Other organisms, like humans and the horse seen below, are consumers and eat food. How is energy released from food, and what is the importance of ATP? Include the name of the process and the overall chemical equation in your explanation
Answer:
The correct answer is - cellular respiration is the process to release energy from food in the form of ATP.
Explanation:
Food, as we know, is the only source of energy for the body but it requires to converted from the form of what we eat which is carbohydrates, protein, fat into an energy source that cells and the body can use for various functions. The process that converts food into energy is cellular respiration.
Cellular respiration is a set of complex chemical reactions that convert sugars into energy in the form of ATP which is the only currency of energy cell can use. The reaction has three stages glycolysis converts glucose in pyruvate, Krebs cycle releases carbon in the form of CO2 from pyruvate, and electron transport which is oxygen-dependent reaction.
Cellular respiration can be understood by the following chemical equation:
C6H1206 + 6O2 ====> 6CO2 + 6H2O + ATP
