Describe solution concentration outside the cell in terms of hypotonic, hypertonic and isotonic.

Answers

Answer:

see below

Explanation:

Hypotonic solution is a very dilute solution to the more concentrated solution. Hypo means under . A solution with a lower concentration of solutes than the cytoplasm of a cell, that solution is hypotonic to the cytoplasm. The cell expands as water moves in.

Hypertonic solution is a more concentrated solution to cytoplasm. Hyper means above. A hypertonic solution has higher concentration of solutes than the cytoplasm of the cell. The cell shrinks as its cytoplasm loses water.

Isotonic solution is when two solutions of equal concentration are separated by a semi permeable. Iso means equal. Therefore, in isotonic solutions, water movement out of a cell balances the water movement into it. Cells in the body are usually surrounded by a fluid. The cytoplasm in the cell is usually isotonic to the fluid outside the cell. Hence, no net gain or loss of water by cells.

So, basically, if a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, there is no net water movement, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.

GIVING BRAINLY!! The relationship between the mass of an object and its weight on Earth is constant.
A True
B) False

Answers

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.

Which of the following is not
one of the kingdoms of living
things?
a Fungi
b. Bacteria
c. Animalia
d. Protista

Answers

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).

1. Gravity also increases

2. Gravitational attraction also decreases

3. Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.

If a DNA molecule with a total of 2500 nucleotides has 1500 purines, how many guanines are in this DNA molecule?

Answers

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.

When exercising routinely, timing the food that you eat around your exercise activities is important and has a significant impact on your energy levels. Carbohydrate intake, in particular, can affect performance, with simple carbohydrates and complex carbohydrates having different ideal times for consumption. The best types of carbohydrates to eat during and/or immediately after exercise are simple carbohydrates, whereas complex carbohydrates are ideally consumed a couple of hours before exercise. Complex carbohydrates take longer to digest and enter the bloodstream and can help build glycogen stores. Sort the following food items

a. Foods rich in simple carbohydrates.
b. Foods rich in complex carbohydrates.
c. Foods without carbohydrates

Answers

Answer:

(a.) Foods rich in simple carbs- Low fat smoothie and sport drinks with glucose

(b.) Foods rich in complex carbs- whole-wheat pancakes, whole-wheat spaggetti with marinara sauce and brown rice with vegetables

(c.) Food without carbs- grilled salmon and roasted chicken breast

Explanation:

Simple carbs are easy to digest and eaten before a workout, hence the sports drink and low-fat smoothie falls under that category, while complex carbohydrates are hard to digest...think anything with wheat.

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?)

Answers

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.
