Answer:

At each link upward in a food web, only a small fraction of the matter consumed at the lower level is transferred upward, to produce growth and release energy in cellular respiration at the higher level. ... At each link in an ecosystem, matter and energy are conserved.

Answer: False

Explanation: The COMPLEMENT SYSTEM consists of proteins synthesized in the liver. They are activated by inespecific harmful substance (antigen) and begins a cascade of proteins that finally forms an attack complex against bacteria.

The COMPLEMENT is part of the INNATE IMMUNITY, because it is an inherent response, something all humans born with, and it is part of the first defense barrier against any antigen. Part of the innate immunity are too: natural killer cells, neutrophils, monocytes, dendritic cells and macrophages.

On the other hand, the ADAPTATIVE IMMUNITY, is the response that the body develops after being exposed to an antigen before. It is like something that the body recognizes, and then "learns" how to act against it. Part of the adaptative immunity are: lymphocyte T and B, and the antibodies (substances called Immunoglobulins). The immunoglobulins (Ig) are glycoproteins present in the blood.

mars1129 [50]

The right answer is C.

Synovia is a viscous biological fluid located at the joints and fulfilling several functions. It limits bone friction between them, dampens shocks, provides the nutrients and dioxygen necessary for chondrocytes (cartilage cells) while eliminating their metabolic waste, and benefits from the presence of immune cells to eliminate possible body foreigners.

Darwin thought that significant evolution was much too slow to be witnessed in a human lifetime. recent experiments by biologist
Ede4ka [16]

Significant evolution, in Darwin's opinion, moves much too slowly to be seen in a person's lifetime. Recent biological tests have demonstrated that some populations may develop extremely quickly, with significant changes happening over many generations in the lab.

What role does Darwin's theory of evolution play?

  • Charles Darwin, a scientist of the 19th century, investigated the idea of natural selection. Natural selection provides an explanation for how a species' genetic features might evolve through time. This might result in speciation, or the creation of a new, separate species.
  • The genesis and adaptations of species entered the scientific canon with Darwin's finding of natural selection. The adaptive characteristics of creatures might now be explained by natural processes, much as the occurrences of the inanimate universe, without the need for an Intelligent Designer.
