What are the identifying features of carbohydrates
Using information from the diagram, state one reason why the movement in the third image represents active transport
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.

During cell reproduction, chromatin fibers coil up into structures called
a. chromosomes
b. lysosomes
c. nucleoli
d. ribosomes
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.

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.
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
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.

Which of the following indicates that an endothermic reaction has occurred?
O Heat is released
O water is formed
O Salt is produced
O Temperature decreases
The following indicates that an endothermic reaction has occurred when temperature decreases, which is in the last option as the endothermic reaction needs heat to carry out the reactions.
What is the significance of the endothermic reaction?There are two types of reactions, such as the reaction that requires heat to form the product, the endothermic reaction, while some of the reactions that release heat are called the exothermic reaction, and the exothermic reactions have more energy at the reactant side than the product side. In the case of a endothermic reaction, the product usually has more energy than the reactants, and the change in free energy here is positive.
Hence, the following indicates that an endothermic reaction has occurred when temperature decreases, which is in the last option as the endothermic reaction needs heat to carry out the reactions.

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?
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.
What is the effect of temperature on ATP,NADPH, and sugars? Will the increase, decrease, or stay the same?
Answer:
1. ATP will increase
2. NADPH will increase
3. Sugar will decrease
Explanation:
Had the same problem
The effect of temperature on these molecules are ;
ATP will increase NADPH will also increase while Sugars will decreaseATP ( Adenosine triphosphate ) is the molecule in cells which stores energy in cells while transferring the energy needed within cells as well. When the temperature of a cell is raised above the required temperature this molecule will also increase in response.
NADPH is an electron donor which is found in organisms, it also provides the reducing power for certain reactions in the organism ( anabolic ) and the gathering of NADPH oxidase. increases as the temperature of the organism increases.
Hence we can conclude that as temperature increases , ATP will increase , NADPH will increase while Sugars will decrease.

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.
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 makes angiosperm more advance than gymnosperm
Answer& Explanation:
Angiosperm is more advanced due to the mechanism of protection it has since developed as opposed to its predecessor, gymnosperm. Angiosperms could be deemed the inventors of animal-mediated pollination or dispersal, whereas gymnosperms mostly depend on wind-mediated pollination (which is far more of a gamble than animal mediated).
1) Angiosperms seeds are enclosed in fruits, which increases the chances of dispersal by either wind, water, or animals. Animals can eat the fruit and disperse the seeds via feces or by brushing the fruit off of their fur coats new areas of the terrain.
2)The development of flowers. Flowers are especially important because depending on the flower it can attract a set species of animals in order for pollination to occur. That species of animal could only focus on those few flowers and would allow the female part of the flower to receive pollen (produced by the male part of the flower) from all over the place. This theory is also applicable to animal mediated fruit dispersal.
What describes G and why they face the watery inside and outside of the cell
Answer:
Because they are hydrophilic
Explanation:
The cell membrane is made up of a phospholipid bilayer. The phospholipid bilayer is made up of an arrangement of phosphate heads, which are (attracted to water) hydrophilic, and fatty acid tails, which are hydrophobic. (repelled by water).
Because they are attracted to water, the phosphate heads face the outside of the cell, where the water is

Answer:
A section of DNA that provides instructions for building a specific protein and A packet of genetic information that can be passed down from one generation to the next
Explanation:
A DNA molecule is not a gene, it is a nucleotide. The entire collection of genetic information in a given species results isn't a gene although many genes comprise what is the genome. Given that those two answers are not what genes are, the other two options are correct.
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
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.
