The responsible for this lifetime immunity is the acquired immune response because antibodies are developed from previous infections. The generation of antibodies is a response to these infections.
The acquired immune system eliminates pathogenic organisms and any toxic molecules they produce.
The acquired immune system has two mechanisms of action: humoral immunity and cellular immunity.
Humoral immunity, also known as antibody-mediated immunity, involves the activation of specific blood cells (B cells) and subsequent secretion of antibodies when in contact with a pathogen.
Thus, the acquired immune system develops specific antibodies as a response to infections (e.g., chickenpox and measles).

Describe the elements and compounds of coal being mined
Answer:
The organic compounds in coal are composed of the elements carbon, hydrogen, oxygen, nitrogen, sulfur, and trace amounts of a variety of other elements
Coal is a mixture of organic compounds and minerals formed from ancient plant material, primarily composed of carbon, hydrogen, and impurities like sulfur and nitrogen.
Coal is a mixture of organic compounds and minerals, resulting from the decomposition of ancient plant material over millions of years. It primarily consists of carbon, hydrogen, oxygen, nitrogen, and sulfur. Carbon, the dominant organic compound, makes up a substantial part of coal's composition, with hydrogen and oxygen occurring in lesser amounts.
Nitrogen and sulfur are present as impurities, in the form of organic compounds and mineral components. Coal also contains inorganic minerals like quartz, clay, and pyrite, contributing to its ash content. Trace elements, such as mercury, arsenic, and lead, are present in low concentrations. The exact composition varies based on coal type and location, influencing its energy content and environmental impacts.

Is GMO is good or bad? And why? Can you please explain to me your answer so that i can understand, thanks!
Answer:
There is no data to indicate that consumption of GMOs is bad for human health. ... In addition, over the two decades that GMOs have been on the market, there have been no occurrences of health issues due to genetically modified organism
Explanation:
but its your own opinion
Answer: GMOs are generally though of as bad
Explanation: GMO stands for Genetically Modified Organism.
People take genes from one plant, lets say from a plant that can withstand cold temperatures, and puts it into another plant. This can give the gene of withstanding cold temperatures to the new plant.
A long time ago people would breed plants until they got traits that they like. This takes a very long time. Now with GMOs, you can get the traits you want much faster.
People are concerned with GMOs for allergies, cancer, and environmental harm. Current research hasn't outlined too many risks of GMOs yet as long-term research is still needed.

Answer:
Your answer is D) Competing with native species of snakes for food
(Sorry if it is wrong)
Explanation:
Pythons compete with native wildlife for food, which includes mammals, birds, and other reptiles. Severe mammal declines in Everglades National Park have been linked to Burmese pythons. Raccoons and opossums often forage for food near the water's edge, which is a habitat frequented by pythons in search of prey.

You've been tasked to study the movements of condensed chromosomes during cell division.
You have access to a magnifying glass, a standard light microscope, a scanning electron
microscope and a transmission electron microscope. Which piece of equipment would you choose
and why? Also why would you NOT choose the others? (max 50 words)
In order to see something as small as a chromosome, It is necessary to employ the use of a scanning electron microscope.
The question states that we wish to study the movements of condensed chromosomes during cellular division. This means that we will need a scope capable of not only looking inside of a cell but even inside of the nucleus of a cell, an extremely minute space.
Logically, a magnifying glass will not be able to accomplish this given that it only allows us to see macroscopic elements, many hundreds of times bigger than what we wish to observe. We run into similar limitations with standard light and transmission microscopes. Although these allow us to see things on a microscopic level, they fall short of the desired capability.
Though the transmission microscope can see even smaller elements than a standard light microscope, both are limited to the surface of cells. The SEM or scanning electron microscope, on the other hand, allows the user to see elements down to 0.1 nanometers in size. Given that chromosomes are between 10 and 30 nanometers in size, we can use this microscope for the desired study.

why do stem get modified give any three examples and explain how this notification help the plant
Answer:
underground stem -- for storage of food ex. potato , ginger.
spines for protection ex. citrus , bougainvillea
Explanation:
Rhizomes and corms are underground stems, modified for the storage of food. Also, these stems help in vegetative reproduction of these plants. The tips of the underground stem in potato plants become swollen due to the accumulation of food. The potato is a tuber that helps in the storage of food and bears eyes on it.
