Is diffusion the only way materials can enter the cell?

Biology
1 answer:
sammy [17]2 years ago
6 0
Diffusion is not the only way for particles to enter the cell. A process called endocytosis is another way for particles to enter cells by active transport. The process means engulfing and requires energy. On the other hand, another active transport process called exocytosis is the process of removing particles from the cells.

How does the skeletal system interact with the nervous system?
Mice21 [21]

Answer:

The skeletal muscles connect to the bones and work with connective tissue at the joints to allow for movement. The muscles connect to the nervous system and allow initiation of movement through nerve signals to and from the brain. The bones and muscles are supported by connective tissue, which plays an integral role in structural support.

Answer:

The test cross is shown below

      T         T

t      Tt         Tt

t       Tt         Tt

The alleles shown in the vertical side (tt) are recessive and come from the male parent. The alleles TT are dominant and come from the female parent.

For the variety of offsprings to be 100% tall, the recessive parent had to be crossed with a homozygous dominant parent.  If the female was heterozygous with which the cross was done,then there would be small tomato plants in the offspring generation.

alex41 [277]

Answer:

r-selected species (e.g., American bullfrog)

Explanation:

The r-selected species (r-strategists) are those species in which their populations oscillate near the carrying capacity, i.e., the maximum population size sustained by a particular environment. These species are generally located in low-quality (less competitive) ecological niches and produce many offsprings that grow rapidly and have low chances of surviving to adulthood. Some examples of r-strategists include amphibians, fish, small mammals, etc. Conversely, K-selected species have more stable populations and produce a low amount of offspring (e.g., large mammals such as elephants).
