Answer:
a. are acid participants in, or by-products of, cellular metabolism
Explanation:
cellular metabolism is the process in which several chemical recation stakes place in body. there aretwo type of cellular metabolism - catabolism and anabolsim, which serves for several body functions.
During the chemical reaction of cellular metabolism, many acids are produced which are called metabolic acids. Several metabolic pathways produces different acids such as carboxylic acid, citric acid and amino acid. All the metabolic acid maintains body's functional activities,if any case acid formation increases it causes metabloic acidosis.
Hence, the correct option is a. "Metabolic acids are the acid participants of celular metablosim".

Answer:
The preferable options for the fill in the blanks will be -
Proto-oncogenes, oncogenes
Explanation:
Proto-oncogenes are a variety of genes that have the potential to subvert the cell's own activities and push it to the malignant state. They encode proteins that have various functions in a cell's normal activities and can be converted to oncogenes.
A proto-oncogene is a normal gene that becomes an oncogene when it is altered by mutation. Oncogenes causes cancer. Some Proto-oncogenes give signals during cell division. Other proto-oncogenes regulate apoptosis (programmed cell death).

What system hosts more biodiversity than any other ecosystem in the oceans?
Answer:
The coral reef
Explanation:
The coral reef system is widely known to be, and arguably the part of the ocean/marine ecosystem that hosts more biodiversity than all other ecosystems. The coral reef has several hundreds of individual reef systems housing up to 25 percent of the total marine life. It includes marine life such as sponges, algae, fishes, various invertebrates etc. It is home to hundreds of beautiful types of corals. The largest reef in the marine habitat is the Great Barrier Reef which is found Australia, covering about 2,400 km.
The coral reef ecosystem hosts more biodiversity than any other ecosystem in the oceans. Despite making up only 1 percent of the marine habitat, coral reefs harbor about one-third of the world's marine fish species. They are vital to maintaining biological diversity and environmental balance in the marine world.
Explanation:The system that hosts more biodiversity than any other ecosystem in the oceans is the coral reef ecosystem, found in shallow ocean waters. Coral reefs are home to a tremendous variety of life and are considered underwater rainforests due to their rich biodiversity. While the deep ocean water and deep ocean surface ecosystems are also vital, supporting large numbers of plankton and krill, coral reefs surpass them in terms of biodiversity.
Coral reefs harbor about one-third of the world's marine fish species, approximately 4,000 species, despite making up only 1 percent of marine habitat. They are also crucial for aquaria, with most marine aquaria stocked with wild-caught organisms from coral reefs. While other ecosystems such as deep ocean water and deep ocean surfaces ecosystems are important for aerobic respirators around the world, coral reefs still hold the highest biodiversity in the ocean.

How are the two kingdoms of bacteria similar?
Answer:
There are two kingdoms of prokaryotes. These are the bacteria (or eubacteria ) and the archaebacteria (or the Archaea ). The members of these two kingdoms appear similar in shape and appearance.
The two kingdoms of bacteria are similar in that both are prokaryotes.
What are the kingdoms of bacteria ?Eubacteria are the most common type of bacteria. They are found in all environments and can be either harmful or beneficial to humans.
Archaea are a group of bacteria that are found in extreme environments, such as hot springs and acidic lakes. They are not as common as eubacteria, but they play an important role in the environment.
The two kingdoms of bacteria are similar in the following ways:
Both are prokaryotes. This means that they do not have a nucleus or other membrane-bound organelles.Both reproduce by binary fission. This is a type of cell division in which one cell divides into two identical daughter cells.Both use DNA as their genetic material.

A botanist created a linear model to predict plant height from soil acidity (pH level) for a certain type of plant. The slope of the model was 2.5 centimeters per pH level, the standard deviation of the sample of plant heights was 4 centimeters, and the standard deviation of the soil acidity was 1 pH level. What is the value of the correlation coefficient?
Answer:
0.625
Explanation:
The slope (m) of a linear regression line is ...
[tex]m=r_{xy}\cdot\dfrac{s_y}{s_x}[/tex]
Then we have ...
[tex]2.5=r_{xy}\cdot\dfrac{4}{1}\\\\\dfrac{2.5}{4}=r_{xy}=0.625[/tex]
The value of the correlation coefficient is 0.625.
Here, we are required to find the value of the correlation coefficient given the slope of the regression model and the standard deviation of the dependent and independent variables.
The value of the correlation coefficient is 0.625
and it is dimensionless.
The relationship between the slope of a regression model and the correlation coefficient is given by;
m = r (Sy/Sx)
where
m= slope of the regression model = 2.5cm/pH.r = the correlation coefficient = ?Sy = The standard deviation of the dependent variable i.e Plant height = 4cmSx = The standard deviation of the independent variable i.e soil acidity(pH level) = 1pHTherefore;
2.5 = r × (4/1)
r = 2.5/4
r = 0.625
P.S: It is important to know that the correlation coefficient is a dimensionless parameter.

write a write a paragraph (3-5 sentences) that explains how and/or why the skull got its name and what language it comes from (like Latin, Greek, etc.) The scientific word for this is called etymology.
Answer:
Middle English scolle ; of unknown origin; compare with Old Norse skoltr . Skull came from both Greek and Roman but I'm pretty sure it originated from Greeks. The word skull is derived from the Middle English word skolle, which in turn is probably a form of the Old Norse word skalli, which means a bald head.
Explanation:
Match the following terms to their proper description:
middle ear, eardrum, inner ear, and the organ of Corti.
1. Contains fluid-filled channels set into the bones of the skull:
2. The organ of hearing:
3. Contains the hammer, anvil and stirrup:
4. Separates the outer ear from the middle ear:
The inner ear contains fluid-filled channels, the organ of Corti is the organ of hearing within the cochlea, the middle ear includes the ossicles (hammer, anvil, stirrup), and the eardrum separates the outer ear from the middle ear.
Explanation:The inner ear contains fluid-filled channels set into the bones of the skull. This region is crucial for both hearing and balance, encompassing the semi-circular canals and the cochlea.
The organ of Corti is the organ of hearing, situated within the cochlea of the inner ear. It contains hair cells that function as sensory receptors for auditory signals.
The middle ear contains the hammer, anvil, and stirrup (malleus, incus, and stapes respectively) which are the ossicles responsible for transmitting sound vibrations to the inner ear.
The eardrum or tympanic membrane is the structure that separates the outer ear from the middle ear, and it vibrates in response to sound waves.
