how much blood is filtered by the kidneys each day?
Answer:
Many times a day, your blood circulates through your kidneys.
Explanation:
Approximately 170 liters per day and 7 liters per hour. About 150 quarts of blood are filtered by your kidneys in a single day relavent to 44 gallons. The tubules are responsible for returning water and other substances to your blood following their filtering through your glomeruli. Approximately one or two quarts of the water becomes urine.
S. aureus is gram positive. What differences in strains might account for differences in phage susceptibilities?
S. aureus is indeed gram-positive but within the bacteria classed as gram-positive, there are differences that might predispose them to infection by phages.
S. aureus as an organism usually adapts to their environment through mutations on their membranes which can be proteins e.g. surface proteins, or receptor molecules e.g. sugar receptors.
In preventing invasion by phages, mutations are gained that prevents attachment to the bacteria cell surface. This effectively prevents the binding of the phage to the bacteria thus preventing infection.
It is also worthy to note that the differences in bacteria strain could range from a few nucleotides to large variations in chromosomes and thus can aid in identifying specific strains that might have beneficial factors in the context of disease prevention.

Which statement about the specific immune response is FALSE?
Each T or B cell has antigen receptors for only one specific antigen.
T and B cells recognize antigens by using antibodies bound to their surface membranes.
Unique antigen receptors are created by genetic recombination.
Antigens must be presented by an MHC molecule for T and B cells to recognize them.
All cells express MHC-I molecules, but only antigen-presenting cells express MHC-II molecules.
explain the significance of chemical digestion!! marking brainliest please help
Answer:
Chemical digestion is a vital part of the digestive process. Without it, your body wouldn't be able to absorb nutrients from the foods you eat. While mechanical digestion involves physical movements, such as chewing and muscle contractions, chemical digestion uses enzymes to break down food.
Which table shows two steps of DNA replication?
DNA replication is a process where the polymerase enzyme adds complementary nucleotide bases in the parent DNA strand, hence option h polymerase matches adenine to thymine is correct.
What is DNA replication?The process by which a double-stranded DNA molecule is duplicated to form two identical DNA molecules is known as DNA replication.
Replication is necessary because when a cell splits, the two new daughter cells must have the same genetic information, or DNA, as the parent cell. In vitro DNA replication (DNA amplification) is also possible (artificially, outside a cell).
To begin DNA synthesis at known sequences in a template DNA molecule, DNA polymerases isolated from cells and artificial DNA primers can be utilized.
Therefore complementary base pairing of nucleotide base pairing, hence option h is correct.

When comparing plant cells to animal cells, which organelle is only present in plant cells?(1 point)
mitochondrion
cell membrane
cytoplasm
cell wall
Answer:
- cell wall -
Explanation:
The answer is a cell wall because the cell wall in a plant acts as a 'skeletal system'.
So tell yourself does, an animal that already has a skeleton, need the cell wall?!
NO! It dan't! That's why animals don't have the cell walls and plants do.
!!! Hoped that helped !!!
When comparing plant cells to animal cells, cell wall is only present in plant cells. The correct option is D.
What is cell wall?A cell wall is a structural layer found just outside the cell membrane that surrounds some types of cells.
It can be tough, flexible, and rigid at times. It provides structural support and protection to the cell, as well as acting as a filtering mechanism.
The cell wall is made up of a network of cellulose microfibrils and cross-linking glycans embedded in a matrix of pectin polysaccharides that is highly cross-linked. Lignin can be found in secondary cell walls.
It provides a structural framework for plant growth and serves as the plant's first line of defense against pathogens.
The cell wall must also retain some flexibility so that it can be rapidly remodeled in response to developmental, biotic, or abiotic stimuli.
Thus, the correct option is D.
