1,455,000 mg
145,000 mg
1,450 mg
1.45 mg
O
145 mg
Answers
Grams can be converted into milligrams by multiplying the amount in grams by 1000. Therefore, 1455 grams will be equivalent to 1,455,000 mg. Thus, the correct option is A.
The conversion of metric units from one unit to another can be done by multiplication or division by powers of 10. If the unit is to be converted into a bigger unit, it has to be divided, whereas if the unit is to be converted into a smaller unit, it has to be multiplied.
Thus, the conversion of gram to milligram is conversion of a unit into a smaller unit and the amount, therefore, has to be multiplied.
There are 1000 milligrams in 1 gram. Therefore, 1,455 grams will have 1000 × 1,455 = 1,455,000 milligrams.

Carson divided 40 unripe bananas evenly among eight paper bags and sealed the bags. He poked 20 small holes in four of the bags and left the other four without holes. He kept the bags at room temperature for three days. Then, Carson opened the bags and counted the number of brown spots on each banana. He compared the average number of brown spots on bananas from bags with holes to the average number of brown spots on bananas from bags without holes.Identify the question that Carson's experiment can best answer.
Answers
Answer:
See the answer below
Explanation:
From the illustration of the experiment, the question that Carson can best answer is that "Do bananas develop more brown spots if they are kept in bags with holes compared to bags without holes?"
The independent variable in the experiment is the hole poked in the bags while the dependent variable is the number of brown spots on each banana. The difference between the subjects is the hole poked in the bags, hence, any difference in the number of brown spots between bananas in the bags with holes and those in the bags without holes can be attributed to the hole poked in the bags.
Therefore, the question that can be answered from the experiment is to see if poking holes in bags make bananas to develop more brown spots compared to bags without holes.

A non-polar fatty acids prevent cell membrane from dissolving in water. The correct option is A.
What is a cell membrane made of?The cell membrane, also known as the plasma membrane, is uncovered in all cells and serves to separate the cell's interior from the outside environment.
The cell membrane is made up of a semipermeable lipid bilayer. The cell membrane controls the transport of materials into and out of the cell.
These are glycerophospholipids, which are molecules made up of glycerol, a phosphate group, and two fatty acid chains. Glycerol is a three-carbon compound that serves as the membrane lipids' backbone.
As, these non-polar fatty acids are insoluble in water, so it protect the cell membrane from water. It actually prevent the cell membrane to get dissolve in the water.
Thus, 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.

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.
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.

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.

Write the overall equation for photosynthesis using words?
Answers
Answer:
carbon dioxide + water =glucose +oxygen
Explanation:
hope this helps :)
The overall equation for photosynthesis using words is:
Carbon dioxide + water + sunlight energy → glucose + oxygen
Photosynthesis in plant chloroplasts and photosynthetic microorganisms is a complex metabolic process. Photosynthesis equation: [tex]CO_2 + H_2O + sunlight = glucose (C_6H_{12}O_6) + O_2.[/tex]
Photosynthesis converts carbon dioxide and water into glucose and oxygen. Special pigments like chlorophyll collect sunlight and transform it into chemical energy.
Photosynthesis underpins the food chain and sustains life on Earth. Primary producers, plants synthesise glucose that sustains all other organisms' growth and development. Photosynthesis provides oxygen for respiration and regulates carbon dioxide levels, preserving Earth's atmosphere.

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.
