Which of the following statements describes one way that energy is transferred in a food web?
Plants provide energy to consumers.
Energy is cycled between producers.
Consumers obtain energy directly from sunlight.
Producers store energy made by animals.
Answer: energy is cycled between producers
Explanation:
Plants provide energy to consumers, herbivorous and decomposers consumers are the only two groups that directly receive energy from plants.
What is a food web?The process of photosynthesis in plants transforms solar energy, which makes up the vast majority of the energy in food webs, into chemical energy.
When molecules are broken down during respiration in plants, a small fraction of this chemical energy is converted directly into heat. From producers to consumers, energy flows.
The relationships between species in a biotic community that involves eating are described by food chains, food webs, and/or food networks. In other words, they demonstrate the flow of resources and energy within an ecosystem from one species to another.
Therefore, plants provide energy to consumers one way that energy is transferred in a food web, hence option A is correct.

Rotenone, a piscicide (fish poison), interferes with the transfer of electrons between Complex I and Complex II in the process shown above. Which of the following results would be expected in the mitochondria of fish exposed to Rotenone? Why?
Answer:
Mitochondria stops working.
Explanation:
When the mitochondria of fish exposed to Rotenone, it inhibits the cellular respiration which is the main cause of death of fishes. This inhibiting of cellular respiration in mitochondria leads to reduction in cellular uptake of oxygen and this reduction is responsible for the death of fishes. This Rotenone releases by the plants present in the water as well as used as pesticides for killing of fishes.

Explanation:
Cell division occurs in two stages: the division of the nucleus, called karyokinesis, and the division of the cytoplasm, called cytokinesis, and both of these include cell division and form two cells from one.
What is the significance of karyokinesis?There are many steps in cell division, two of which are important, the first is the division of the nucleus, known as karyokinesis, which is the process of nuclear division that includes replication of the genetic material and separation of the duplicated chromosomes and is important for the production of genetically identical daughter cells for growth and repair in multicellular organisms. The single cell is divided into two cells after cytokinesis, which occurs at the end of cell division.
Hence, cell division occurs in two stages: the division of the nucleus, called karyokinesis, and the division of the cytoplasm, called cytokinesis, and both of these include cell division and form two cells from one.

How does the muscular system help humans maintain posture?
1.Muscles continually align themselves vertically to help maintain posture.
2.Muscles continually push bones to be straight.
3.Muscles constantly contract to help fight gravity.
4.Muscles constantly contract to help work with gravity.
Answer:
a
Explanation:
Muscles continually align themselves vertically to help maintain posture.
What is Muscular system?Muscle fibers are specialized cells that make up the muscular system. Their ability to contract is its main characteristic. Movement is caused by muscles that are connected to blood vessels, internal organs, or bones.
Muscle contraction is the primary cause of almost all bodily movement. Cilia, the flagellum on sperm cells, and certain white blood cell amoeboid movement are examples of exceptions to this rule.
Walking and running are two examples of visible movements that are produced by the coordinated action of joints, bones, and skeletal muscles. Skeletal muscles can also make softer motions that influence different facial expressions, eye movements, and breathing.
Therefore, Muscles continually align themselves vertically to help maintain posture.

A.Gravity slab pull
B.The gravity of the Moon and Sun
C.Heat from the Earth's core causing mantle convection
Answer:
Option C
Explanation:
Driving force for plate tectonics is the "convection in the Earths mantle" or option C. Convection is the transfer of heat due to the movement in molecules also causing hot to rise and cold to sink. Convection currents cause the tectonic plates to move because the currents rise to the Earths surface forcing the plates to drive away from each other also known as seafloor spreading.
