Answer:

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.

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.

5. Consider two soil samples, one from a tropical rain forest and the other from a temperate
deciduous forest Predict which sample would have a greater concentration of organic
material Explain your answer

Answers

Answer:

Temperate deciduous forest

Explanation:

The temperate deciduous forest will have more organic matter concentration in it.

Organic matter is a component of biological relics found in the soil. It makes up a significant portion of the soil.

Soil organic matter should not be confused with biomass production. Rainforest due to its biodiversity is rich in organic biomass. These organic matter decays rapidly due to the humid conditions, and are become lost. Also, the rate of weathering in the rainforest is very high. This often washes and removes organic matter from the soil. These conditions are not so in the temperate forest.

How does energy cycle or "flow" during aerobic respiration?

Answers

Answer:

Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body's cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.

Explanation:

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.

c. nucleoli
d. ribosomes

Answers

it is a. chromosomes

During cell reproduction, chromatin fibers coil up into structures called chromosomes. Therefore, the correct option is A.

What are chromosomes?

Chromosomes are structures made up of DNA and proteins that are found in the nucleus of the cell. They contain genetic information That are responsible for the inherited characteristics of the organisms such as eye color, hair color, height etc.

Chromosomes play a crucial role in cell division, as they ensure the proper distribution of genetic material to the daughter cells.

During cell division, chromosomes are replicated and then separated into daughter cells, ensuring that each cell receives a complete set of chromosome.

The number and arrangement of a chromosome vary depending on the species, but all human cells except the sperm and egg cell contains 23 pairs of chromosomes. Hence, the correct option is A.

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.

Carbohydrates are one of three macronutrients, besides protein and fat, that you need in fairly large quantities to maintain your life and important body functions. They are revered for their ability to energize you quickly but also blamed for thickening waistlines in the rise of so-called low-carb diets. Nutritionists and public health officials still encourage you to get most of your calories from this nutrient, so it's important to learn to identify high-quality, healthy carbohydrates.

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.

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.

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.
