In which biological event is chemical energy transformed into mechanical energy?
O muscular movement
O
photosynthesis
O bioluminescence
Muscular movement is the correct answer
The event in which the chemical energy transformed into mechanical energy is muscular movement. The correct option is A.
What is muscular movement?Muscles contract and then relax to move body parts. Muscles can pull bones, and yet they can't push them back into position.
As a result, they function in pairs of flexors and extensors. To flex a limb at a joint, the flexor contracts.
We discussed the skeletal system and the gestures that can take place at joints, such as flexion, extension, abduction, inversion, and so on.
These movements are produced by skeletal muscles pulling bones in different directions.
When ATP is hydrolyzed during cross-bridge cycling, chemical energy is converted to mechanical energy during muscle contraction.
As the muscle deforms or performs external work, this mechanical energy is distributed and stored in the tissue.
Thus, the correct option is A.

As DNA replication continues and the replication bubble expands, the parental double helix is unwound and separated into its two component strands.
a. True
b. False
Answer:
As DNA replication continues and the replication bubble expands, the parental double helix is unwound and separated into its two component strands. This unwinding and separating of the DNA require three different types of proteins: helicase, topoisomerase, and single-strand binding proteins.

A model cell with damaged DNA was created to explain the importance of checkpoints in a cell cycle. The G2 checkpoint accidentally failed to work during experimentation. What do you think is the likely consequence of this failure?.
Answer: the consequenc of this failure is The cell continued to divide uncontrollably to create more damaged cells Which can lead to deadly diseases like cancer, breast cancer and many more
If the G2 checkpoint accidentally failed, then the cell will enter into division. The likely consequence of this failure is that the cell proliferates in an uncontrolled manner.
The cell cycle is controlled by checkpoints that regulate the progression through different phases of the cell cycle.
The G2 checkpoint acts to prevent the entry in mitosis of cells that have damages in its genetic material (DNA) in order to repair it.
When the cell undergoes failures in the G2 checkpoint control, the cell divides in an uncontrollable manner and thus generate groups of damaged cells (e.g., a tumor).

Small aquatic organisms, such as coral, are the producers of the ocean. Please select the best answer from the choices provided T F.
The marine invertebrates of phylum Cnidaria are called corals. Corals are important as they build reefs in oceans and feed on planktons.
The given statement is :
True
The position of corals can be explained as:
The corals are both a primary producer as well as the consumer.They take energy from algae through the mutual relation between both organisms. The corals feed on planktons, zooplanktons and phytoplankton for energy so they are consumers.The algae living in coral make food for them and corals produce oxygen.
Therefore, corals are producers.

Mitosis is cell division of (germ, somatic) cells. The purpose of mitosis is to create new cells for
and
Mitosis produces four (different, identical) cells that are (diploid,
haploid)
Answer:
Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells. Below we highlight the keys differences and similarities between the two types of cell division.
Explanation:
Involves one cell division?
Results in two daughter cells
Results in diploid? daughter cells? (chromosome? number remains the same as parent cell)
Daughter cells are genetically identical
Occurs in all organisms except viruses
Creates all body cells (somatic?) apart from the germ cells? (eggs and sperm)
Prophase is much shorter
No recombination/crossing over occurs in prophase.
In metaphase individual chromosomes (pairs of chromatids) line up along the equator.
During anaphase the sister chromatids are separated to opposite poles.
Fossil evidence indicates that the first organisms on Earth were single-called prokaryotes. The first eukaryotes are believed to have formed from these prokaryotes. How does the endosymbiotic theory explain the development of the first eukaryotic organisms?.
The study of fossils shows that the eukaryotic cells have been evolved from the prokaryotic cells. The endosymbiotic theory has been used to study the evolution of eukaryotic cells.
The endosymbiotic theory states that:
Endosymbiotic theory is also referred to as the theory of symbiogenesis. The theory explains the evolution of eukaryotic cells from prokaryotic cells. The theory explains the presence of chloroplasts and mitochondria, and how these organelles form the eukaryotic cells. The theory explains the origin of mitochondria in animal cells and chloroplasts in plant cells.
Thus, the endosymbiotic theory defines the development of eukaryotic cells from the prokaryotic cells.
