The answer is A.) Antibodies are formed that fight those types of bacteria.
To explain, your immune system protects you from invasive bacteria by attacking and destroying them. The problem is that your system needs to recognize invading organisms like bacteria. Remember that bacteria cells have many of the same types of structures as your own cells, and you do not want your immune system to attack your own body. Special cells called T-cells and B-cells participate in this process. To make a long story short, antibodies are special molecules that your immune system "labels" invading bacteria with, so that it knows what to attack. These antibodies only fit on molecular structures of the targeted bacteria.
When a dead or weakened bacteria, or even pieces of a bad bacteria are introduced to the body, the B-cells and T-cells create antibodies that label that specific type of bacteria, or even its parts. They also remember how to make them in the future, so that later, when and if infected with a live version of that bacteria, the immune system already makes the antibodies to fight that infection. The process can work for viruses too.
The atmosphere also protects living things on Earth from the sun's harmful ultraviolet radiation. The atmosphere also helps to sustain life of Earth. It provides oxygen for humans and animals to breathe, and carbon dioxide for plants.
Unlike light sound cannot travel through a vaccum. An example of a vacum is outer space. You can see lights from space, but can not hear sounds from space
Cell technology most likely benefited the commercial flower industry in this following way : Growers can create new flower colors without using cross-pollination
Through cell technology, they only need to alter the Colors from its Genetics in the cell.
hope this helps
Answer:
a.) rate of population growth
Explanation:
The population growth rate determines how a population will be distributed in a region. Populations with a high growth rate need to occupy more spaces, in addition to needing to consume a greater volume of natural resources. As the population grows, the distribution in the region becomes more intense, the opposite also happens. When the population growth rate indicates that the population is decreasing it means that this population will need less space and therefore, its geographic distribution will be smaller, as well as its impact on the region.
