Response:
Both living and non-living factors influence the survival and reproductive success of fish within an ecosystem.
The presence of various predators for a specific type of fish will affect its survival and breeding rates. More predators can threaten the fish's ability to thrive within that ecosystem, leading to potential predation.
The quantity of prey also impacts fish survival; fewer prey means greater competition for resources among species.
Non-living variables, like salt concentration in water, can also affect fish survival and reproduction. A species not adapted to saline environments could be wiped out due to rising salt levels in its habitat.
Additionally, human actions, such as dumping waste into water bodies or allowing fertilizers to drain into aquatic ecosystems, can severely harm the survival and breeding rates of certain aquatic species.
Explanation:
A gene is a segment of DNA that typically contains the code for a particular protein influencing a specific trait, while an allele is a segment (a version) of that gene. The correct choice among the options is option "D".
Response:
vaccine
bacteria
pathogens
cells
toxins
antibiotics
Clarification:
Bacterial meningitis is a severe infection leading to the Inflammation of the membranes surrounding the brain and spinal cord.
This infection is typically viral but can also be caused by fungi and bacteria. A vaccine is necessary to combat bacterial meningitis. Common signs include fever, neck stiffness, and headaches. It spreads through bacteria found in the throat of an infected individual and can be transmitted via coughing, sneezing, or kissing. The bacteria serve as pathogens that emit a toxin , which damages cells and components of the nervous system.
This condition is treated with intravenous antibiotics and corticosteroids in some cases.
Therefore, the correct sequential responses for the blanks are vaccine, bacteria, pathogens, cells, toxins, and antibiotics.
Answer:
B) Lysosome
Explanation:
Lysosomes are organelles within eukaryotic cells, characterized by a covering of double membranes and an internal composition of hydrolytic enzymes. These enzymes, commonly referred to as digestive enzymes, play important roles in catalyzing the breakdown of proteins and various complex molecules. Examples of hydrolytic enzymes located within lysosomes include proteases, glycosidases, and phosphatases.
