Both Lamarck and Darwin made pivotal observations regarding traits related to inheritance in their studies. While each theorized different origins for these traits, they agreed that over time, individuals obtain characteristics referred to as inheritance. Lamarck proposed that traits are inherited from parents to their offspring, whereas Darwin believed they arise from the process of natural selection.
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:
Answer:
Exocrine glands are characterized by discharging their secretions into duct systems.
Explanation:
Exocrine glands:
These glands transport their secretions through a network of ducts that ultimately connect to the body's exterior. This means there is a direct continuity between the interior surfaces of the glands and their duct system with the external surfaces of the body (like the skin).
Examples of exocrine glands include gastric glands, salivary glands, and sweat glands.
The potato does not increase in size because it is only a segment of the plant. Water absorbed from the soil is taken up by the roots and transported to other parts like leaves, but the potato itself does not directly absorb water from the soil.
