does variation allow for natural selection to take place?
Answer: HOPE THIS HELPS!
Variation allows some individuals within a population to adapt to the changing environment. Because natural selection acts directly only on phenotypes, more genetic variation within a population usually enables more phenotypic variation.
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.

In 2006, an Ethiopian researcher announced the discovery of well-preserved 3.3 million-year-old fossil of a young female hominid. Refer to Figure (F) below. Considering the Hominid trend of evolution, choose which skull would most likely be that most primitive of the three.
Answer:
Skull three
Explanation:
the backlining is in more, and the jaw moves out more, resembeling that of a more gorilla like creature
It sounds like the description is referring to a hominid with a more pronounced facial structure, similar to that of a gorilla. This may indicate a more primitive stage of hominid evolution, as earlier hominids had more pronounced facial features and a more protruding jaw than later, more advanced hominids.
What is the basic evolutionary changes in the group mentioned ?As hominids evolved over time, their facial features became more refined, and their jaw became less protruding as they adapted to a diet that relied less on tough, fibrous vegetation and more on softer, cooked foods. This adaptation allowed for the development of a larger braincase and a more upright posture, both of which are hallmarks of later hominids such as Homo erectus and Homo sapiens.
It's worth noting that the evolution of hominids is a complex and ongoing area of research, and new discoveries and interpretations of existing evidence may change our understanding of the evolutionary timeline and the characteristics of different hominid species.
Over the course of hominid evolution, several important changes occurred that distinguish hominids from other primates. One of the earliest changes was the development of bipedalism, or the ability to walk on two legs. Bipedalism allowed hominids to free their hands for tool use and other tasks, and also facilitated the long-distance travel needed to explore new environments.

Efforts to reduce pollution began occurring later in the century. If pollution near factories was reduced, what would happen to the color of the moths? Explain your answer.This would happen because
Answer:
moths would begin becoming lighter as the pollution is reduced
Explanation:
The color of the moths would begin becoming lighter as the pollution is reduced. This is because during the time of high amounts of pollution industrial melanism takes place and the moth's pigmentation becomes a darker tone. This is so that the moths are able to blend in better with its surroundings and survive. Pollution causes sulphur dioxide gas and dark soot deposits which have a greyish dark tone, thats why moths pigmentation turns darker. With pollution reduced moths need a lighter colored pigment to blend into lighter colored objects such as trees and leaves.
The color of the Moths will become lighter as a result of this due to the effect
pollution has on its color.
Industries and factories make use of fuel and when it is burned in generating
sets and other equipment it produces the compound known as Nitrogen
oxide.
The Nitrogen oxide has a brownish color which goes into the atmosphere
where the moths fly in thereby contact with the gas darkens the color to
shades of brown. A reduction in the discharge of the gas will lead to it
becoming lighter.

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.
