Answer:
am ecosystem is where a system is formed by organisms interacting with one another and their physical environment
Answer:
b. Segments can become specialized on a particular function
Explanation:
Segmentation conditions virtually every aspect of the structure and functioning of animals with a consecutive body. Generally speaking, we can say that the main advantage of segmentation is that each segment can become specialized in a specific function.
One of its advantages is related to locomotion and comes, on the one hand, from the fact that the volume of celiac fluid remains constant in each compartment, acting as an antagonistic force against which muscles can act and, on the other, from the possibility of independently control each segment
. This allows the peristaltic movement (circular muscle contraction wave followed by longitudinal muscle contraction) to be localized and involve only those muscles that are strictly necessary, making the movement's energy needs considerably more profitable.
The compartmentalization of the body led to the repetition of structures, namely excretory, nervous and circulatory in each segment. This can be seen as another advantage of segmentation as it may lessen the impact of damage to the animal's body; Undamaged segments can maintain their normal functions and thus increase the likelihood that the animal will overcome the damage sustained.
Another advantage is that segmentation allows modification of certain portions of the body to perform specialized functions such as feeding, locomotion and reproduction.
Explanation:
Both Darwin and Mendel proposed their theory at the same time but they never communicated with each other. They both explained the population and studied the variation between them and in them.
The variation within a population could be of two types: the discontinuous traits and the quantitative trait.
A discrete trait refers to a trait that is usually controlled by only one gene that is only two alleles or two variants are observed in the population whereas the quantitative trait is a trait that can be determined by more than one gene like the variation in height.
True. such as with pesticides, they are used to reduce harmful insects to crops but they often re harmful to the health of people consuming those crops
Answer and Explanation:
Throughout the world, the most different species of organisms are insects. As compared to the other species, the number of insect species is greater. The exact number of insect species can be estimated from previous and current studies. Approximately nine hundred thousand species of insects are known. Insectivorous birds are those birds that feed on insects. For numerous growing insectivorous birds, insects are used as a source of protein. One of the most common kinds of insects is beetles. They are found everywhere. Beetles eat fruits, leaves, and other parts of the plant. The reproductive and fertility ability of insects is remarkable. In habitat 2, beetles and insectivorous birds were living. If all insectivorous birds and remaining beetles were removed from habitat, two and five hundred additional light tan beetles and 500 dark brown beetles were released in habitat 2. After one more week, one thousand dark brown beetles would be expected to be recaptured in the habitat 2.
