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.
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.

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.
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.

Mode of action of aldehydes and Quaternary ammonium compounds is
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.
A certain animal species has either curly tails (C) or straight tails (c) and either hazel eyes (H) or blue eyes ( h). What are the possible genotypes of an animal with curly tails and blue eyes
Answer:
CChh
Cchh
Explanation:
Cc or CC can be a genotype for curly tails because both have a dominant allele for curly tails
hh can be a genotype for blue eyes because there are two recessive alleles for blue eyes that are present

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.
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

Which of these organelles prepares proteins to be fully functional?
A. Rough endoplasmic reticulum
B. Large vacuoles
C. Smooth endoplasmic reticulum
D. Chloroplasts
Rough endoplasmic reticulum
Answer:
Rough endoplasmic reticulum is among the organelles that are found in eukaryotic cells. The reason as to why it is called rough is because it has ribosomes attached to its surface. Its main function is to produce proteins.
Explanation:
Explain the role of cellular respiration in a cell.
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.

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
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
Which critter trait is affected by an environmental factor, such as light, temperature, or
diet? Explain.
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.

Calculate the number of neutrons in atoms of the isotope 3919K
With working out
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.
The islets of Langerhans are surrounded by
A-exocrine cells that produce digestive fluid.
B-endocrine cells that produce digestive fluid.
C- exocrine cells that produce glycogen
D-B and C
PLEASE HELP ME ITS REALLY URGENT CAUSE I HAVE EXAMS TOMORROW!!!
Answer:
A-exocrine cells that produce digestive fluid.
Explanation:
The pancreas is composed of both exocrine cells (capable of producing digestive enzymes) and endocrine cells (involved in the production of hormones that control glucose homeostasis). The islets of Langerhans are clusters or 'islands' of pancreatic endocrine cells, which consist of α-cells that produce glucagon, β-cells that secrete insulin and δ-cells that produce somatostatin. These islets are surrounded by: 1-exocrine cells called 'acini' that produce digestive enzymes such as chymotrypsin, trypsinogen, lipase, and elastase; and 2-bile ductules, which are tubes that carry bile from the liver and the gallbladder through the pancreas.

Answer:
EeWw
Explanation:
The allele for the earlobe is depicted as e while that of the hairline is w.
A parent that is homzygous recessive for earlobes (ee) and homzygous dominant for hairline (WW) would have the genotype eeWW.
The other parent that is homzygous dominant for unattached earlobes and homzygous recessive for hairline would have the genotype EEww
eeWW x EEww
During meiosis, each genotype will form gametes.
eeWW: eW, eW, eW, eW
EEww: Ew, Ew, Ew, Ew
These gametes will randomly unite during fertilization to produce offspring. Since the same gametes are formed by each parent:
eW x Ew
offspring
100% EeWw (see the attached image for the Punnet's square)
The genotype of all the children would be EeWw and would phenotypically be with unattached earlobes and dominant hairline.
