An animal cell with a 30% salt solution is placed in a beaker with a 20% salt
solution. Which is the correct conclusion if the cell remains in the beaker for an
extended period of time?

Answers

Answer:

the animal cell will burst

Explanation:

If the salt solution in the animal cell is 30%, it means the water is at a 70% concentration. Outside is 20%, so the water is 80%.

Water will enter the cell. Water is at a higher concentration outside the cell (80%) or a lower concentration inside the cell (70%) by the process of osmosis.

Eventually, the animal cell will burst, because it does not have any cell wall to control the swelling of the cell that occurs as water flows in.

The INDEPENDENT VARIABLE:

A. Is the participant
B. Is what the scientists manipulate in the experiment
C. The component that is measured. D. The results of the experiment​

Answers

Answer:

B. Is what the scientists manipulate in the experiment.

Explanation:

The Independent variable is not dependent, or doesn't rely, on another variable in the experiment. So, it would make the most sense that they would manipulate the Independent so that they can watch and see how the dependent variable reacts to the manipulation, or the change, in the independent variable.

Plz mark my answer brainliest✍️✍️

Explanation:

Arrows have come to represent protection and defence from any evil that can come to you. Sustenance – Arrows were used to fight enemies and to hunt food, two important aspects of sustaining life. As a result, an arrow symbolizes maintaining and protecting life.

REAL NAME - SHRESTH DUBEY

The arrows in a food chain represent the flow of energy or the transfer of nutrients between different organisms in an ecosystem.

They indicate the direction of energy transfer, showing which organism is being consumed by another. The arrow always points from the organism being consumed (prey) to the organism consuming it (predator).

The primary producers, such as plants or algae, are at the beginning of the food chain and transfer energy to herbivores (primary consumers), which are then consumed by carnivores (secondary consumers) or other higher-level consumers.

The arrows help depict the interconnectedness and energy flow within an ecosystem, illustrating the feeding relationships between organisms.

Using information from the diagram, state one reason why the movement in the third image represents active transport

Answers

Answer:

A protein or ion has passed through the "pump" or carrier proteins and move within the cell.

Nvm short and sweet ;)

Further info..

To move substances against a concentration or an electrochemical gradient, the cell must use energy. This energy is harvested from ATP that is generated through cellular metabolism. Active transport mechanisms, collectively called pumps or carrier proteins, work against electrochemical gradients. With the exception of ions, small substances constantly pass through plasma membranes. Active transport maintains concentrations of ions and other substances needed by living cells in the face of these passive changes. Much of a cell’s supply of metabolic energy may be spent maintaining these processes. Because active transport mechanisms depend on cellular metabolism for energy, they are sensitive to many metabolic poisons that interfere with the supply of ATP.

PLEASE ANSWER ASAP. Thank you. QUESTION: Explain the evidence that suggests that the universe is expanding.

Answers

One piece of evidence that proves that the universe is expanding is that there is a direct relationship between the speeds of distant galaxies and their distances from Earth. In fact, Hubble discovered that the farther away a galaxy is, the faster it is moving away from us. Although scientists today still don’t know the nature of this mysterious energy causing this acceleration, Hubble’s evidence has strengthened many theories about the large-scale structure of the universe.

How do oxbow lakes form? A. It is formed as lakes grow larger due to erosion and begins to look like an ox. B. It is formed when a bend in a river is cut off to form a lake. C. It is formed when a delta grows large enough to cut off a river to form a lake. D. It is formed when a dam stops the flow of a river and creates a lake.

Answers

Answer:

Oxbow lake is formed when a bend in a river is cut off to form a lake.

Explanation:

OPTON A - It is formed as lakes grow larger due to erosion and begins to look like an ox.

This statement is incorrect , as the shape of the oxbow lake is not like an ox , it is a horse-shoe shaped lake .

OPTION B - It is formed when a bend in a river is cut off to form a lake.

This statement is correct , as  An oxbow lake is a U-shaped lake that forms to create a free-standing body of water when a large meander of a river is cut off.

OPTION C - It is formed when a delta grows large enough to cut off a river to form a lake.

This statement is also wrong, as a river delta is specified by this statement.

OPTION D - It is formed when a dam stops the flow of a river and creates a lake.

This statement is also false, since the creation of a reservoir is established by this statement.

FORMATION OF OXBOW LAKE -:The neck of the meander gets narrower and narrower progressively. The curve gradually grows so close that the river slices through the neck of the meander to take a new, straighter path. Sediment locks the end of the old loop over time. This leaves a region of water that is different, called an oxbow lake.

Hence , the correct option is B.

What is electronegativity?

The term "electronegativity" describes how attracted an atom is to the bonding electrons in molecules as opposed to other atoms.

American chemist Linus Pauling developed a set of dimensionless variables known as electronegativity values that vary from a little under one for alkali metals to a maximum of four for fluorine.

Electropositive elements are those that are on the left of the periodic table and have low electronegativities. We shall use the key attribute of the order of electronegativities F > O > N > C to explain the chemical properties of organic molecules.

Therefore, Zinc 1.65, Chromium 1.66, Tungsten 2.36 and Iodine 2.66.

A company wants to build a new store. After reviewing the piece of land it is determined that a threatened woodpecker nests in that area .If the company is granted permission to build , what is the most environmentally responsible action by the company

Answers

Answer:

Explanation:

If the piece of land is forested or covered with many trees, the company can decide not to bring down all the trees (leaving some trees standing) and move as many as possible nests to the available trees within it's land. This will prevent emigration of the woodpeckers and can ultimately help conserve the woodpeckers in that land and indeed the area in which the land is situated.

This is most environmentally friendly because killing or scaring away of the birds by destroying there homes could lead to imbalance in the environment and even cause gradual extinction of the birds in the environment/area.

With the boost in warmer weather and excess water, populations will boom

Explanation:

Yabbies will do best at a water temperature of between 12°C and 20°C but they will tolerate water that is a little colder or warmer. Complete immersion in water is not essential for life for the yabby. If its gills are kept moist (humid air is sufficient), it can absorb oxygen from the air and survive for many days out of water. To breed, however, it must be in water. With the water needed for breading and warmer weather used for breeding, population numbers for the Yabbies should rise.
