Some human white blood cells help destroy pathogenic bacteria by *
(1) causing mutations in the bacteria
(2) engulfing and digesting the bacteria
(3) producing toxins that compete with bacterial toxins
O (4) inserting part of their DNA into the bacterial cells
Answer:
2
Explanation:
They either engulfy and digest pathogens(phagocytosis) or produces antibodies.
Some human white blood cells help destroy pathogenic bacteria by engulfing and digesting the bacteria. The correct option is B.
Thus, By engulfing pathogenic bacteria through a process known as phagocytosis, some human white blood cells, notably phagocytes like neutrophils and macrophages, aid in the destruction of pathogenic germs.
These phagocytes have the capacity to identify and bind to bacteria, creating a phagosome—a membrane-bound compartment—around the bacterium.
The phagosome then joins forces with lysosomes, which are organelles that carry digesting enzymes, to create a phagolysosome. The bacteria are exposed to the lysosomal enzymes inside the phagolysosome, which causes them to break down and die.
Thus, Some human white blood cells help destroy pathogenic bacteria by engulfing and digesting the bacteria. The correct option is B.

In one or two sentences, explain how cats and dogs, both mammals, could be classified as distinct animals. What characteristics set them apart from one another?
Answer:
Cats and dogs are both mammals because they have hair, are warm-blooded, and nourish their young with milk. Dogs and cats are distinct species, incapable of producing offspring together because of the many differences in their genome.
Explanation:
i hope this was helpful!
Mammals are warm-blooded vertebrate(backbone) animal distinguished by hair or fur on their body.
Mammals give birth to younger ones.Female mammals produce milk in their mammary gland to feed the younger ones.Examples of mammals includes, Huma being, lion, dog, tiger, cat, horse, goat, cow etc.
Since, cats and dogs are both mammals, the difference between them is the genome.Genome is the complete genetic information (DNA or RNA) of an organism.Cats and dogs have different genetic information.

She is puzzled that the clone does not have an effect, even though she knows, based on available mutants, that loss of the function of this gene causes worms to die as larvae. You look at the sequence of the DNA she used to make the feeding clone and discover that it corresponds to an intron in the gene. What would you say to the student to explain why her experiment did not succeed
Hello. Your question is incomplete, which makes it difficult to answer, but we can consider that the girl's experiment went wrong because she used a DNA sequence that only corresponds to introns that are not capable of encoding amino acids. Therefore, you could explain to the girl that her experiment did not work, because the introns do not encode amino acids, which prevents the clones from developing proteins that are essential for their survival, since the amino acids are the protein-building molecules .
Introns are important for the control of gene expression, but they cannot encode any amino acid, without which the organism cannot survive.
how proteins are made
Proteins are an important class of molecules that carry out most of the work inside cells. The building blocks of proteins are smaller organic molecules called amino acids. Most organisms, including humans, use only 20 different amino acids to assemble the vast multitude of proteins needed to build and run a cell.
To build proteins, cells use a complex assembly of molecules called a ribosome. The ribosome assembles amino acids into the proper order and links them together via peptide bonds. This process, known as translation, creates a long string of amino acids called a polypeptide chain.
After the polypeptide chain is synthesized, it will sometimes undergo additional processing. For example, some proteins will have certain amino acids removed. Or extra molecules such as sugars or phosphates may be attached to some of the amino acids in a protein.
Answer:
proteins are made of large numbers of amino acids joined end to end. The chains fold up to form 3d molecules with complex shapes - you could think of it as origami with very long and thin piece of paper

C
The Hill Country will see a decrease then an increase in species diversity because all of the old species will be replaced by new species.
D
The Hill Country will see an increase in species diversity because the soil has been enriched by the ash.
