Explanation:
d. Antelopes with musclar legs are able to outrun their predators better than antelopes with poop muscle tone. thus they lived to reproduce.
Antelopes with muscular legs are able to outrun their predators better than antelopes with poor muscle tone, thus they lived to reproduce. This best illustrates the relationship between variations within a population and natural selection.
What is Evolution ?
The process by which populations of organisms change over generations is known as evolution. These modifications are based on genetic variations. Gene variants, also known as mutations, or the normal process of genetic material being rearranged as a cell prepares to divide (known as genetic recombination) can cause genetic variations. An organism may acquire new characteristics as a result of genetic variations that alter protein function or gene activity. In the event that a characteristic is favorable and helps the individual get by and replicate, the hereditary variety is bound to be passed to the future (a cycle known as normal determination). The advantageous trait becomes increasingly common in a population over time, making it distinct from an ancestral population as generations of people with the trait continue to reproduce. Occasionally, the population becomes so distinct that it is regarded as a new species.Evolution is not influenced by all variants. Only hereditary variants, which are found in sperm or egg cells, can be passed down through generations and have the potential to influence evolution. Because some variants are not inherited and only exist in a small number of a person's body cells over their lifetime, natural selection cannot be a factor. Also, many genetic changes are neither beneficial nor harmful because they have no effect on how a gene or protein works. A population of organisms' environment also plays a significant role in the selection of traits. Variants can introduce differences into an organism that may help it survive in one environment but not in another. For instance, resistance to a particular bacteria is only beneficial if that bacteria is found in a specific location and harms the people who live there.

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.

Why OR Why shouldnt we build power plants in france? PLEASE anwser question thoroughly!!!
Answer:
We should not build more power plants in France because of a few reasons. reason 1 carbon emissions are terrible for our planet and we already have enough pollution. reason 2 we have a very low fuel supply as it is and using it up for things we don't need is not sufficient. Reason 3 is money. France is in a debt of 3,403.24 euros. we should not be spending what we don't have. These are the reasons why we should not build power plants in France.
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.

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.
