Answer:
Cells of the immune system are able to respond to the presence of invading organisms because they recognize the antibodies present in the invading pathogen
Explanation:
The mechanisms of human immunity can be grouped into two broad categories: the innate or nonspecific immune system, which provides a first and general defense against any element recognized as foreign, and the acquired or specific immune system that recognizes specific threatening agents and generates a response directed against those elements. When foreign substances enter our body (bacteria, viruses, parasites, proteins from other animal or plant species, cells from other organisms - including those of human origin - and a long etcetera, all of which are given the common name of antigens) and are brought into contact with cells that are members of the immune system, the foreign element or antigen is first captured by certain types of cells that are collectively known as antigen-presenting cells. These cells would correspond to the intelligence service and their mission is to take the antigens, introduce them inside, process them and present the antigens on their surface in a fragmentary way to other cells of the immune system. This results in the activation of lymphocytes that specifically recognize the antigen and ends in the development of mechanisms that mediate the physiological function of the response, that is, the elimination of the antigen. Thus, the immune response can be functionally divided into three phases: the antigen recognition phase, the activation phase of the response, and the effector phase.

Is the relationship between Riftia pachyptila and the chemosynthetic bacteria an example of symbiosis?
Answer: YES. The relationship between Riftia pachyptila and the chemosynthetic bacteria is an example of SYMBIOSIS.
Explanation:
Nutrition is the series of process by which living organisms obtain food substances and use them to provide energy and materials for their growth and maintenance. There are 2 major modes of nutrition which includes:
--> Heterotrophic nutrition: this is the type of nutrition in which the organism depends on manufactured food for survival. Heterotrophic organisms may be SYMBIOTIC which means that it can live together with another organism as they both benefit from each other.
--> Autotrophic nutrition is the type of nutrition in which an organism has the ability to manufacture its own food. This can be achieved through the process of CHEMOSYNTHESIS. In this process, they synthesis organic compounds with the use of energy from inorganic compounds such as carbondioxide. An example is the chemosynthetic bacteria found in the gut of Riftia pachyptila.
Riftia pachyptila is an aquatic invertebrate that is seen at the seafloor near hydrothermal vents ( high temperature area). They do not have digestive system that will enable them make use of the inorganic materials (carbondioxide, sulphide) found in their environment. But within their paired coelomic cavities are chemosynthetic bacteria.
The relationship between Riftia pachyptila and the chemosynthetic bacteria is an example of SYMBIOSIS because the chemosynthetic bacteria depends of the Riftia pachyptila for the necessary inorganic compounds for its own metabolic reactions and excretion of by products while Riftia pachyptila depend on the bacteria for byproducts from its metabolic reaction which is needed for its growth.
YES, the connection between Riftia pachyptila and therefore the chemosynthetic bacteria is an example of SYMBIOSIS.
Nutrition-Nutrition is the series of processes by which living organisms obtain food substances and use them to supply energy and materials for growth and maintenance.
There are 2 major modes of nutrition which includes:Heterotrophic nutrition is the sort of nutrition during which the organism depends on manufactured food for survival.Autotrophic nutrition is the sort of nutrition during which an organism has the power to manufacture its own food. this will be achieved through the method of CHEMOSYNTHESIS.Riftia pachyptila is an aquatic invertebrate that's seen at the seafloor near hydrothermal vents ( heat area).
They do not have gastrointestinal system which will enable them make use of the inorganic materials (carbondioxide, sulphide) found in their environment. But within their paired coelomic cavities are chemosynthetic bacteria.
The relationship between Riftia pachyptila and therefore the chemosynthetic bacteria, chemosynthetic bacteria depends on the Riftia pachyptila for the required inorganic compounds.
For its own metabolic reactions and excretion of by-products Riftia pachyptila depends upon the bacteria for byproducts from its metabolic reaction which is required for its growth.
Therefore, Yes, the relationship between Riftia pachyptila and the chemosynthetic bacteria are an example of symbiosis.

During Earth's early history, microbial life on land contributed to the formation of soil. Soil formation, in turn, led to the evolution of land plants. Which term describes this chain of events?
Answer:
The correct answer is - nitrogen fixation.
Explanation:
In soil formation microbes play an important role as they help in providing important compounds such as nitrogen by the process of nitrogen fixation that is used by the plants.
Nitrogen-fixing organisms mostly bacteria are free-living but some live in a symbiotic relationship with plants such as Azobacter or with other organisms such as Rhizobium.

How do humans cycle carbon from the biosphere to the atmosphere? (1 point)
by respiration
by driving cars that use gasoline for fuel
by eating plants
by planting vegetable crops
Answer:
Carbon is the chemical backbone of life on Earth. Carbon compounds regulate the Earth’s temperature, make up the food that sustains us, and provide energy that fuels our global economy.
Explanation:
Humans cycle carbon from the biosphere to the atmosphere by respiration, driving cars that use gasoline for fuel, eating plant parts, planting vegetable crops. So, all these processes are playing a major role in the carbon cycling by Humans.
What is Carbon Cycle?
The movement of carbon from the reservoir to reservoir is known as the carbon cycle. The carbon Cycle occurs through the atmosphere, oceans, and through living and dead organisms.
Humans during respiration inhale Oxygen and exhale Carbon-dioxide, vehicles also emit smoke consisting mainly of carbon, plants' bodies also contain a proportion of carbon.
Therefore, Humans cycle carbon from the biosphere to the atmosphere by respiration, driving cars that use gasoline for fuel, eating plant parts, planting vegetable crops. So, all these processes are playing a major role in the carbon cycling by Humans.

What conditions are necessary for rocks to melt? ( I’ll give a Brainliast) please answer
Answer:
The rock is pulled down by movements in the earth's crust and gets hotter and hotter as it goes deeper. It takes temperatures between 600 and 1,300 degrees Celsius (1,100 and 2,400 degrees Fahrenheit) to melt a rock, turning it into a substance called magma (molten rock).
Answer:
Flux melting occurs when water or carbon dioxide is added to rock. These compounds cause the rock to melt at lower temperatures. This creates magma in places where it originally maintained a solid structure. Much like heat transfer, flux melting also occurs around subduction zones.

if the checkpoint finds an error, what are some actions the cell can take to ensure the error does not get replicated?
Answer:
If the checkpoint mechanisms detect problems with the DNA, the cell cycle is halted, and the cell attempts to either complete DNA replication or repair the damaged DNA. If the damage is irreparable, the cell may undergo apoptosis, or programmed cell death 2.
Explanation:
um i think this is correct. hope this helps and have a nice day
-KindnessMatters-
The cell cycle is the intricate process of replication of genetic material and producing the daughter cells. The cell cycle is regulated by several mechanisms, one of which is checkpoints.
Checkpoints are the sites where the cells are checked for errors and inaccuracy in the cell.
The cell takes action to ensure errors are not replicated as:
The G1 checkpoint in the cell cycle is the primary checkpoint, which decided whether the cell should divide or not divide. It checks for size, DNA damage, and nutrients. The cell cycle will halt if there will be any errors. The G2 checkpoint is involved in the overall smoothening of the cell cycle. If any damage is observed after the other checkpoints, the cell cycle will pause in the G2 phase, halting the replication of errored genetic material.The M checkpoint corresponds to accurate attachment of the sister chromatids and the cycle will be in pause if the proper attachment is not done.
Thus, there are several checkpoints to check the errors in the DNA, and if any error persists, the cell cycle will be halted.
