In general, freshwater fish require salinity (salt) levels of 1.0 ppt or lower. You measure the salinity of a freshwater aquarium to be 3.0 ppt. Predict what will happen to the cells of the fish as a result of the salinity level in the aquarium.
1) Is tank water hyper, hypo or isotonic to the fish cells? Explain why.
2) Based on your answer to part 1, what will this type of solution ultimately do to the cells of the fish? ( which way will the water move into or out of the fish cells?)
The cells of the fish will lose water to the aquarium water by osmosis, shrink up, and probably die with time.
1) The tank water is hypertonic to the cells of the fish. Hypertonic solutions are those with higher solute concentrations compared to the sap of the cells placed in them. Hypotonic solutions have lower while isotonic solutions have the same concentrations as the sap of cells placed in them.
2) Because the tank water is hypertonic, the cells of the fish will lose water to the water in the aquarium. When this happens, the cells shrink, and may eventually start dying if the situation remains unchanged enough.

Answer:
lactic acid.
Explanation:
Fermentation is a metabolic process that produces chemical changes in organic substrates through the action of enzymes. In biochemistry, it is narrowly defined as the extraction of energy from carbohydrates in the absence of oxygen. In food production, it may more broadly refer to any process in which the activity of microorganisms brings about a desirable change to a foodstuff or beverage.[1] The science of fermentation is known as zymology.

If a DNA molecule with a total of 2500 nucleotides has 1500 purines, how many guanines are in this DNA molecule?
Answer:
I'm pretty sure there would be 1000 guanines in the DNA molecule.
Explanation:
Hope this helps. . . <3
If a DNA molecule with a total of 2500 nucleotides has 1500 purines, total number of guanines are in this DNA molecule is 1000 guanines in the DNA molecule.
What will be the total number of thymines if a DNA molecule has a total of 1500nucleotides?The DNA molecules would be given and it have 450 thymines if the DNA molecule has the total of 1500 nucleotides and the DNA molecule also have been known as the deoxyribonucleic acid has been made up of the double helix. The DNA molecule with the total of 1500 nucleotides would contain 750 cytosine and Thymines and 750 guanines and adenine.
Hence, we can have the expression:
C + T = 750
If there are 300 cytosines, hence;
300 + T = 750
T = 750 - 300
T = 450
A nucleotide has the monomer constituting DNA or RNA biopolymer molecules and the double-stranded DNA molecule posseses two strands of DNA made up of the nucleotides.
Therefore, If a DNA molecule with a total of 2500 nucleotides has 1500 purines, total number of guanines are in this DNA molecule is 1000 guanines in the DNA molecule.

Which of the following is not
one of the kingdoms of living
things?
a Fungi
b. Bacteria
c. Animalia
d. Protista
Answer:
B. Bacteria
Explanation:
Because bacteria are unicellular organisms belonging to the prokaryotic group where the organisms lack a few organelles and a true nucleus
Bacteria is not one of the kingdoms of living things. So, the correct option is (B).
What are the Different kingdoms of Living things?Living things are divided into 5 kingdoms. These are:
1. Monera
It is the kingdom of microscopic living things that groups together prokaryotes (archaea and bacteria) present in all habitats and composed of single-celled things without a defined nucleus. Bacteria belongs to this kingdom.
2. Protista
This group is primitive of eukaryotic which is paraphyletic which includes common ancestor but not all its descendants. Protozoa belongs to this kingdom.
3. Fungi
This kingdom includes yeasts, molds and all species of mushrooms and toadstools, which are multicellular aerobic heterotrophic eukaryotes, have chitin in their cell walls, feed on other living things, and reproduce by means of spores.
4. Plantae
Trees, plants belong to the kingdom Plantae, which is characterized by its sedentary, multicellular and eukaryotic nature. They are autotrophs, whose cells contain cellulose and chlorophyll which are essential for life on Earth as they release oxygen through photosynthesis.
5. Animalia
The kingdom Animalia is divided into two major groups – vertebrates and invertebrates which are multi-celled, heterotrophic eukaryotes that have aerobic respiration, sexual reproduction and the ability to move. This kingdom includes mammals, fish, birds, reptiles, amphibians, insects, molluscs and annelids.
Thus, Bacteria is not one of the kingdoms of living things. So, the correct option is (B).

GIVING BRAINLY!! The relationship between the mass of an object and its weight on Earth is constant.
A True
B) False
Answer:
The mass of an object is never zero. You measure mass with an ordinary balance on Earth or an inertial balance in space. Weight depends on the effect of gravity, so it can change depending on where it's measured. In the absence of gravity, weight can be zero.

What microscope magnifies up to 100,000x
Answer:
electron microscope
Explanation:
An electron microscope is a microscope that uses a beam of accelerated electrons as a source of illumination. As the wavelength of an electron can be up to 100,000 times shorter than that of visible light photons, electron microscopes have a higher resolving power than light microscopes and can reveal the structure of smaller objects.

Describe how leaves of green plants are suited for photosynthesis.
This is a very interesting question, even somewhat mind boggling.
You’ve heard of mitochondria, right? Organelles in embedded in the cells of macro-organisms, such as ourselves, and that carry their own trimmed down genetic code in DNA? Well their is another organelle in cells that has DNA separate from that of the macro-organism. That is the chloroplast, which is what constitutes the green coloration in plant tissue and is where photosynthesis is done in the plant. Chloroplasts have DNA also.
Now, how is that you may well ask. Why would mitochondria and chloroplasts have their own DNA separate from that of the organism that otherwise completely surrounds and sustains them?
Scientists are pretty convinced by now that it is because both mitochondria and chloroplasts used to be free living organisms on their own. At some point in the early history of life, they became symbiotic and then dependent on unicellular host organisms. The dependence, however, was reciprocated, as neither humans nor plants (with significant exceptions) can live without chloroplasts.
So the main adaptation of plants to do photosynthesis has been to incorporate chloroplasts into their own cells and then further adapt their inputs of water and nutrients to take advantage of that.
