What is immunity?
That is my question

Answers

Answer 1
Answer:

Answer:

In biology, immunity is the balanced state of multicellular organisms having adequate biological defenses to fight infection, disease, or other unwanted biological invasion, while having adequate tolerance to avoid allergy, and autoimmune diseases.
Answer 2
Answer: the ability of an organism to resist a particular infection or toxin by the action of specific antibodies or sensitized white blood cells.

Passive immunity is provided when a person is given antibodies to a disease rather than producing them through his or her own immune system.

A newborn baby acquires passive immunity from its mother through the placenta. A person can also get passive immunity through antibody-containing blood products such as immune globulin, which may be given when immediate protection from a specific disease is needed. This is the major advantage to passive immunity; protection is immediate, whereas active immunity takes time (usually several weeks) to develop.

However, passive immunity lasts only for a few weeks or months. Only active immunity is long-lasting.

Active immunity results when exposure to a disease organism triggers the immune system to produce antibodies to that disease. Exposure to the disease organism can occur through infection with the actual disease (resulting in natural immunity), or introduction of a killed or weakened form of the disease organism through vaccination (vaccine-induced immunity). Either way, if an immune person comes into contact with that disease in the future, their immune system will recognize it and immediately produce the antibodies needed to fight it.

Active immunity is long-lasting, and sometimes life-long.

5. A is probably an outgroup while B and C are sister taxa
6. C is probably an outgroup while A and B are sister taxa

Answers

Answer:

1 and 6 are correct

Explanation:

1. A and B are probably closely related - true, as reflected by their close gene sequences which usually represents a very close genetic relationship

2. B and C are probably closely related  - false, if their gene sequences are very different then they are probably not so closely related

3. A and C are probably closely related  - false, we know A and B are close, and B and C are very different, therefore A is probably also very different

4. B is probably an outgroup while A and C are sister taxa  - false, A and B are highly similar

5. A is probably an outgroup while B and C are sister taxa  - false, B and C are very different genetically

6. C is probably an outgroup while A and B are sister taxa - true, we know A and B share similar gene sequences, whereas C is distinct.

HELPWhat is the primary goal of sustainable farming?
o
testing and adopting new technologies for agriculture
developing new crops to grow while still growing traditional varieties
o meeting current needs while preserving resources for the future
O
decreasing short-term costs and increasing long-term income​

Answers

Answer:

-meeting current needs while preserving resources for the future

Explanation:

Sustainability involves meeting developmental goals while maintaining ecological balance and preserving natural resources for the future. Similarly, sustainable farming describes the way agricultural practices can be improved via the use of technologies for small and industrial-sized farms, in both the local and global economies. Social responsibility, while providing adequate food, goods and services, is just one benefit to sustainable agriculture. This approach is also based on the improvement of environmental responsibility and economic efficiency for the sake of future generations.

Name a human alimentary canalinwhich digestion of food not occurs can it oesophagus

Answers

True. The Esophagus is the alimentary canal of the human body in which digestion does not occur. The alimentary canal is the where the food travels that starts from the mouth unto the anus.

Frozen clay takes up more space than thawed clay does. Adding water to clay and then freezing it breaks the clay apart more than either freezing it or adding water to it alone.
