A microbiologist is conducting a research project on chemolithoautotrophs. This means that the investigator is examining certain aspects of a bacterium that is a purple nonsulfur bacteria which depends on light. uses light as its energy source and carbon for organic compounds. can oxidize inorganic molecules such as ammonia and sulfur for energy. can use the energy from sunlight to build organic molecules from carbon dioxide. obtains carbon from organic molecules.
Answers
Answer:
uses light as its energy source and carbon for organic compounds.
Explanation:
The purple non-sulfur bacteria which depends on light produces organic food just like plants through the process of photosynthesis. The purple non-sulfur bacteria uses carbondioxide and water with sunlight produces oxygen and glucose which is an organic compound. So that's why purple non-sulfur bacteria is also known as phototrophic means organism that produces their own food through photosynthesis.

The most direct method by which an ion or molecule can move across a cell membrane is by ____________.A. using an integral protein.B. a sodium-potassium pump.C. simple diffusion. D. active transport.E. osmosis.
Answers
Answer:
C. Simple diffusion
Explanation:
Simple diffusion from a high to low concentration is the most direct method that ions or molecules can move across a cell membrane.
Through this method, no proteins are required for transport, and no energy is used.
The ion or molecule being transported directly moves across the cell membrane, without any other factors involved.
So, the correct answer is C. Simple diffusion

Answers
Answer:
Chitin.
Explanation:
The structure that is not a component of wall of sponges is Chitin. Their body comprise of calcareous or siliceous spicules or protein spongin fibres. Choanocytes are the distinctive cells located in the interior body walls of sponges. Sponges are similar to other animals in many characteristics such as they are multicellular, heterotrophic, lack cell walls and produce sperm cells in order to produce offspring sexually and also different from animals due to lack of tissues and organs.

Calculate the number of neutrons in atoms of the isotope 3919K
With working out
Answers
Answer:
20 neutrons
Explanation:
In the atom of an element, there exists three subatomic particles namely; proton, neutron and electron etc. The sum of the number of neutrons and number of protons (a.k.a atomic number) in an atom makes up the mass number.
In this question, an element was given as follows: 39- 19 K meaning that the mass number is 39 but the atomic number is 19.
Hence,
no of. neutrons = mass no. - atomic no.
39 - 19 = 20 neutrons.

PNS axons are vulnerable to cuts, crushing injuries, and other types of trauma. However, a damaged ____________ can regenerate if the ____________ remains intact and a critical amount of ____________ remains. The success of peripheral nervous system axon regeneration depends upon two primary factors: (1) the amount of ____________ and (2) the ____________ between the site of the damaged axon and the ____________ . The possibility of repair is ____________ with an increase in either of these two factors. Neurolemmocytes play an active role in regeneration
Answers
Answer:
The correct answer is - damaged, effector organ, neurilemma, damage, distance, cell body, decreased.
Explanation:
PNS axons are prone to cuts, and other types of injuries. A damaged axon can regenerate if the effector organ remains intact and a critical amount of neurilemma is found.
The degree of success of these axons regeneration depends upon factors that are (1) the amount of damage, and (2) the distance between the site of the damaged axon and the cell body it innervates The possibility of repair is reduced with an increase in either of these two factors. Neurolemmocytes play an active role in regeneration

Mode of action of aldehydes and Quaternary ammonium compounds is
Answers
Answer:
Aldehydes have antibacterial, antifungal, antiviral and sporicidal activity. These are helpful to destroy the spores of Bacillus subtilis and Clostridium sporogenes. Glutaraldehyde and formaldehyde are commonly used aldehydes in disinfectants.
Quaternary ammonium compounds work by denaturing the proteins of the bacterial or fungal cell, affecting the metabolic reactions of the cell and causing vital substances to leak out of the cell, causing death.

Answers
Answer:
Tallness.
Explanation:
Tallness is the critter trait that is affected by an environmental factor, such as light, temperature, or diet because the organism remains short if they are not getting food properly as well as temperature. Food provides essential nutrients that contribute in the growth of organism. Suitable temperature of the body allows the different functions in the body to be done which directly affects the growth of the body and the organism becomes taller.

Explain the role of cellular respiration in a cell.
Answers
Answer:
Every cell performs a type of cellular respiration as it is required to produce energy. The point of cellular respiration is to turn high-energy molecules, know as glucose, into ATP, a form of usable energy. There are two types of respiration, aerobic and anaerobic. Aerobic goes through 3 stages and produces the most ATP by using oxygen and releasing carbon dioxide. Anaerobic does the same job but only uses one stage and produces much less ATP. This process gives the cell energy and continues the carbon cycle.

Every day we make choices that can potentially affect our environment. For example, we may toss a plastic drink bottle into the nearby trash because it’s more convenient than walking all the way to the recycling bin. Think about three choices you made this week that could have affected the environment. Did your choices have a positive or a negative effect on the environment? Explain your reasoning.
Answers
Secondly, my family owns a compost bin and compost machine that helps compost vegetable waste, fruit scraps, coffee grounds, and other compostable items. Choosing to do this helps the environment in many ways.
Thirdly, I picked up many aluminum cans on the side of the road to crush and collect. After several months of collecting them in a container, my family and I bring them to a place that recycles and reuses metals and aluminum.
The three choices that could have affected the environment are as follows:
Utilization of plastic to make it easy for carrying objects.Plants trees in order to build a green environment. Overdependency on vehicles rather bicycles and pedestrians. What is Environment?The environment may be defined as anything which is present in the surroundings of living organisms. This environment basically has two types of factors biotic and abiotic factors.
In the above three choices, building a green environment has a positive effect on the environment. It may also affect living organisms positively. While the rest of the two may stimulate a negative impact on the environment by increasing the levels of carbon dioxide by liberating emission and non-biodegradable plastics.
Therefore, the three choices that could have affected the environment are well mentioned above.
