Which example is a representation of the amount of chemical energy at each trophic level?
energy pyramid
primary productivity
food chain
joule
Answer:
food chain
Explanation:
The energy pyramid is a representation of the amount of chemical energy at each trophic level. Therefore option A is correct.
An energy pyramid is a graphical representation of the amount of chemical energy available at each trophic level in an ecosystem. It shows the flow of energy from one trophic level to the next, with energy decreasing as it moves up the pyramid.
The primary producers (plants or autotrophs) occupy the bottom level and contain the most energy. As energy is transferred to higher trophic levels through consumption, it decreases, resulting in fewer organisms and less energy available at each subsequent level.
Energy pyramids help illustrate the inefficiency of energy transfer in ecosystems and the importance of a stable base of primary producers to support higher-level consumers.
Therefore option A is correct.

Which of these is NOT a reason for mitosis in humans?
to grow
to make sperm and egg cells for reproduction
to heal
to replace dead cells
Answer:
to heal..
Explanation:
Answer: To make sperm and egg cells for reproduction
Explanation:
Cell division happens in humans and most other animals by mitosis and meiosis. When a cell divides by way of mitosis, it produces two clones of itself, each with the same number of chromosomes. When a cell divides through meiosis, it produces four cells, called gametes. Gametes are also called sperm in males and eggs in females.
Unlike in mitosis, the gametes produced by meiosis are not clones of the original cell, because each gamete has exactly half as many chromosomes as the original cell.
In healing and growth, mitosis occurs beacuse the body clones cells to produce more of the exact same kind of that body part.

Explanation:
Are both strands of DNA copied continuously during replication? Explain your answer.
Answer:
Since the two strands of a DNA double helix are antiparallel, this 5′-to-3′ DNA synthesis can take place continuously on only one of the strands at a replication fork (the leading strand). On the lagging strand, short DNA fragments must be made by a “backstitching” process.

Which of the following is correct about classifying organisms in science?
A
They are classified in a hierarchical system, with the largest group sharing only a few characteristics at the top, and the smallest group sharing the most characteristics at the bottom.
B
They are classified in a numerical system, where the top tier classifies organisms with the largest populations, and the lowest tier classifies organisms with the smallest populations.
C
They are classified in a chronological system, starting with the first organisms discovered by people and through to the most recently discovered organisms.
D
They are classified in a geographical system, where the organisms are listed alphabetically by country, and the countries are ordered by number of organisms they possess.
It aids in both the identification of living things and the comprehension of their diversity. We may learn about the characteristics, similarities, and differences of many plant and animal species thanks to classification. Thus, option C is correct.
What classifying organisms in science?The study of relationships among living things is known as taxonomy, and the formal classification of species into groups based on those supposed relationships is known as taxonomy. The similarities and differences between organisms are used to classify them.
Scientists classify things using a branching method. The domain is the largest category. Kingdoms are the next level of division within each domain, followed by phyla, classes, orders, families, genus, and species. It helps us comprehend how more sophisticated organisms develop from less complicated ones.
Therefore, They are classified in a chronological system, starting with the first organisms discovered by people and through to the most recently discovered organisms.

How do auxins cause plants to bend?
A) Auxins make plant cells grow larger towards the light causing it to bend.
B) Auxins make plant cells grow heavier causing it to tip on one side.
C) Auxins cause plants to grow wider.
D) Auxins cause plant cells to shrink on one side making it less heavy, which tips the plant on the other side.
Answer:A) Auxins make plant cells grow larger towards the light causing it to bend.
Answer:
A.
Auxins make plant cells grow larger towards the light causing it to bend.
Explanation:
The auxins go more in the shady side, and that is why there are more auxins in the shady side, but in the illuminated side, there are less auxins. That will cause a bend in the growth of the plant towards the light source because the shady side has more auxins to make it grow. This is the reason why when there are auxins in a plant, they start to grow towards light.
