Active and passive humoral immunity are both mechanisms of adaptive immunity that use antibodies. yes this is true

  • Our adaptive immune system protects us from infection-related mortality. An new-born born with a significantly compromised adaptive immune system may die shortly unless extreme steps are taken to isolate it from a wide range of infectious agents such as bacteria, viruses, fungi, and parasites.
  • The purpose of adaptive immunity is to eliminate invading infections as well as any harmful chemicals they create. Because these reactions are damaging, it is critical that they only occur in response to molecules that are alien to the host and not to molecules that are native to the host. The adaptive immune system's capacity to identify what is foreign from what is self is a fundamental feature.

The secretion of a signal molecule by a cell into the local environment
Elodia [21]

Answer:

paracrine signaling.

Explanation:

Chemical signaling between cells is one of the most important ways that activities of tissues and  organs are coordinated. The nervous system is the other major coordinating system in animals,  but even here chemical signaling is used between adjacent neurons. The mechanisms involved are  described as either being paracrine, autocrine, intracrine, endocrine, neuroendocrine or  pheromones. Paracrine signals diffuse locally and act on neighboring cells.

Which statement is the correct contrast to the mistaken idea of spontaneous generation?
kramer

All organisms reproduce either sexually or asexually is the correct contrast to the mistaken idea of spontaneous generation

C . all the organisms reproduce either sexually or asexually

<u>Explanation:</u>

The organism could not arise only through the sexually and the asexual reproduction but it is also reproduced through the process of spontaneous generation.

The essential character is offspring is while mother supply is the only solid substrates. The reproduction also takes place by either the egg of the mother or the sperm of the father and began to grow when it is stimulated. Spontaneous generation is defined as the living creature that could arise from nonliving matter.

What will charles darwin have to say about lamarcks theory?
iragen [17]
He would say that Lamarck's theory is wrong. Lamarck's theory stated that traits that are used are passed on to the offspring. In other words, if an organism changes during its lifetime in order to adapt to its environment, then its changes will be passed on to its offspring. This is wrong because this means that organisms pass on traits based on genetic information and not based on the environment of the offspring.

Hope this helps.
