which type of bacteria synthesise their own food with the help of inorganic compounds such as sulphur ?
Chemoautotrophs are able to synthesize their own organic molecules from the fixation of carbon dioxide. These organisms are able to produce their own source of food, or energy. The energy required for this process comes from the oxidation of inorganic molecules such as iron, sulfur or magnesium

How are photosynthesis and cellular respiration different?
Answer:
photosynthesis is what organisms use to create food and energy. this comes from the sun. and cellular respiration is carbon dioxide that comes from the animal after photosynthesis
Explanation:
Answer:
The answer is Cellular respiration breaks down glucose; photosynthesis creates glucose.
Explanation:
This is the answer because In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct. In cellular respiration, oxygen is used to break down glucose, releasing chemical energy and heat in the process.

In squash, yellow seeds are dominant over green seeds. If two heterozygous yellow seed squash were crossed, what are the genotype and phenotype results? (Your "work" should show THREE things - the completed Punnett square, the possible genotypes, and possible phenotypes.)
Answer:
The result of cross two squashes with yellow seeds is an offspring of squash with green seeds -dominant caracter- heterozygous and yellow seeds squashes in a genotype proportion 1:2:1 and phenotype proportion 3:1
Explanation:
The cross of two heterozygous individuals for a characteristic results in an offspring that will have both characteristics in pure and heterozygous form. It is a cross monohybrid which complies with the principle of independent segregation exposed by Mendel.
For the characteristic "seed color" the green color would be G and yellow represented as g.
At the cross of two heterozygous squashs:
- Parents: Gg X Gg
- Punnett's Square:
Alleles G g
G GG Gg
g Gg gg
Offspring:
A pumpkin of green seeds GG (25%)Two pumpkins of green heterozygous seeds Gg (50%)One pumpkin of yellow seeds gg (25%)Genotype proportion 1:2:1
Phenotype proportion 3:1

A scientist grew an Elodea plant in a freshwater aquarium. She
removed a leaf from the plant and placed the leaf in a hypertonic
solution containing 8% salt in order to observe what happened to the
cells within the leaf. When she looked at the cells under a microscope,
she noticed that the cells in the leaf shrunk. Which statement best
explains what caused the cells to shrink?
A. The hypertonic solution caused the water in the cell to move from the
cytoplasm into the nucleus.
B. The salt moved from the hypertonic solution into the cell and
chemically bonded with the water.
C. The salt within the cell moved through the cell membrane into the
solution with the higher salt concentration.
D. The water within the cell moved through the cell membrane into the
solution with the lower water concentration.
Answer: D. The water within the cell moved through the cell membrane into the solution with the lower water concentration.
Explanation:
Osmosis is the process of movement of water or any other fluid from a region of higher concentration to a region of lower concentration across a semipermeable membrane.
A hypertonic solution is the one which has higher solute concentration and low solvent concentration.
According to the given situation, the scientist when placed the leaf in the hypertonic solution containing 8% salt solution. The water in the leaf cells will move out of the leaf due to osmosis and the leaf will shrink. As the 8% salt solution is hypertonic.

Where are plankton-eating fish most likely to live in a freshwater lake?
O A. The profundal zone
B. The limnetic zone
C. The littoral zone
D. The pelagic zone
Planktons are microscopic organisms that live in the water and perform photosynthesis. Plankton-eating fish are most likely to be found in the limnetic zone. Thus, option B is correct.
What is a limnetic zone?The limnetic zone is one of the ecological zones of the lake, the other zones are littoral, profundal, euphotic, and benthic. The limnetic zone is the area of the lake with ample sunlight and is where the planktons dwell.
Microscopic organisms like cyanobacteria, phytoplankton, zooplankton, and other algae are found in this zone. They play a crucial role in the aquatic ecosystem as they can use the sunlight to produce energy and are food for other consumers.
Therefore, option B. the plankton-eating fish are most probably found in the limnetic zone of the lake.

Describe how the hydrogen ion pump stores energy in a new place
Answer:
Hydrogen ion (H+) pumps work against their concentration gradient and therefore they need energy inputs from sources such as ATP
Explanation:
The hydrogen ion (H+) pumps are proteins that move protons across biological membranes. These pumps use energy in the form of ATP in order to generate a proton gradient on one side of the membrane. For example, in plants, H+ pump ATPases are able to generate an electrochemical gradient in the plasma membrane. In this case, the proton gradient is employed to drive secondary transport processes, thereby enabling the uptake of diferent metabolites such as nutrients, sugars, amino acids, etc., from the extracellular space.

what is the role of decomposers in an ecosystem?
Answer:
Decomposers are responsible for breaking down dead animals bodies into waste, more commonly known as food for themselves, and a more clean ecosystem. You can thank decomposers such as mushrooms and fungi for making sure the ecosystem does not consist of dead bodies.
Answer:
Decomposers play a critical role in the flow of energy through an ecosystem. They break apart dead organisms into simpler inorganic materials, making nutrients available to primary producers.

In a brief paragraph, explain how soluble proteins were obtained from fish muscle samples. Your explanation should include:
1. the purpose of mincing (cutting) and vortexing the tissue [2 pts,]
2. the purpose of the homogenization buffer [2 pts,] and
3. the purpose of the centrifugation step [2 pts.]
You must clearly describe what role each of these played in extracting and solubilizing protein from the samples to receive full credit. Revisit the "Micropipetting and Preparing Solutions" exercise to remind yourself of what the ingredients in the homogenization buffer were.
Answer:
Explanation:
This question is a practical question, however the processes involved in obtaining proteins after "sacrifice" is similar.
After removing the desired muscle sample from the fish during sacrifice, the muscle sample can be stored temporarily in a phosphate buffer saline which can also help remove blood and some other contaminants around the muscle sample. The sample can then be removed and weighed with the desired mass cut into small pieces in order to achieve a smaller surface area which assists for easy homogenization and buffer interaction. The homogenization buffer (which can be a phosphate buffer) is added to this small pieces and then "vortexed" so that the buffer can interact properly with the pieces. The purpose of the homogenization buffer is to prevent osmotic damage in the muscle cells while maintaining a constant pH (depending on the protein to be obtained). After homogenization with an homogenizer, the muscle cell membrane is ruptured and the soluble proteins dissolves into homogenization buffer (which must also be soluble to the desired protein) with a mass of suspended muscle tissues also in the buffer. This mixture is then centrifuged so as to obtain the dissolved/soluble protein (in the homogenization buffer) and separate it from the suspended masses in the mixture.

Explain why the process of mitosis is important to you eukaryotic
organisms
The eukaryotic organisms have the process of mitosis but differently than the process of the prokaryotic because the prokaryotic organisms dont have the dna enclosed in a nucleus. Mitosis needs to occur in eukaryotic organims because the cell could keep growing an it is going to be less efficient in moving material across the cell membrane. They reason why mitosis happens is because volume and surface are do not increase at the same rate.
