Explanation:
Two groups of proteins, called cyclins and cyclin-dependent kinases (Cdks), are responsible for the progress of the cell the. A phosphatase is an enzyme that removes a phosphate group from a protein. Together, these two families of enzymes act to modulate the activities of the proteins in a cell, often in response to external stimuli. Rough the various checkpoints. What genes destroy cancerous cells? The primary function of the p53 gene is to repair or destroy defective cells, thereby controlling potential cancerous cells. This type of gene is called an anti-oncogene or tumor suppressor gene Cancer growth blockers are also called cancer growth inhibitors. They are a type of targeted cancer drug. Our body makes chemicals called growth factors that control cell growth. Cancer growth blockers work by blocking the growth factors that trigger cancer cells to divide and grow. There are many types of cancer growth blockers that work in different ways..

what types of solute molecules may be moved by facilitated diffiusion
Explanation:
Facilitated diffusion therefore allows polar and charged molecules, such as carbohydrates, amino acids, nucleosides, and ions, to cross the plasma membrane. Two classes of proteins that mediate facilitated diffusion are generally distinguished: carrier proteins and channel proteins.

23. Where are earthquakes most likely to
occur?
A where Earth's tectonic plates are
moving together
B where
magma cools slowly beneath
Earth's surface
C where Earth's lithosphere is in
constant, slow motion
D where Earth's seafloor is spreading
into deep ocean trenches
Answer:
D where Earth's seafloor is spreading into deep ocean trenches
Explanation:
Over 80 per cent of large earthquakes occur around the edges of the Pacific Ocean, an area known as the 'Ring of Fire'; this where the Pacific plate is being subducted beneath the surrounding plates. The Ring of Fire is the most seismically and volcanically active zone in the world.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.

differentiation
Explanation:
Itt is the process by which cells become different cells such root or stem cells. This is found in the stem cell and all plant cells have stem cells property.
During the differentiation, the cells change in the cell morphology, membrane potential , and metabolic activity
Therefore, Differentiation is the process by which some of a plants cells become root cells and other become stem cells.
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.

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).

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.

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.
