Answer:
Some factors that may cause a decrease in population size:
- a high mortality rate due to an infectious disease
- a low birth rate
- a high mortality rate due to interspecific competence
- a high emigration rate
Explanation:
In biology, population size (N) refers to the total number of individuals in a given population. The four main factors that affect population size are birthrate (natality), death rate, immigration rate (i.e., the number of individuals of a given species that move into a population), and emigration rate (i.e., the number of individuals of a given species that move out of a population). Both birthrate and immigration are known to increase N, while death rate and emigration are rates known to decrease this value.

Explanation:
The bones in the forelimbs of penguins and seals are best described as analogous, while the flippers of penguins and seals are homologous.
Analogous structures are structures that are similar in different organisms, even though they are unrelated to each other. For instance, the wings of birds and the fins of a penguin or a fish.
Homologous structures are similar structures in related organisms. Both the penguins and the seals have flippers. Another example is the human arm and the wings of a bat. Both have similar structures internally, but while a human lifts items with their hands, the birds use theirs for flying.
Answer:
an organism is the highest level of organization
Explanation:
a tissue is a group of cells of the same function and shape working together
an organ is a group of tissues working together to perform a specific task
an organ system is two or more organs working together to execute a specific process
an organism is all organ systems functioning together to provide all process necessary for living
The
inflammatory response
(inflammation) occurs when tissues are injured. Leukocytes and plasma proteins gather to inflame the area to fight infection. is a nonspecific defense reaction to tissue damage caused by injury or infection
Has a definite shape and volume -> Solid
