List 5 uses for proteins in the cell.
Answer:
Protein has many roles in your body. It helps repair and build your body’s tissues, allows metabolic reactions to take place and coordinates bodily functions. In addition to providing your body with a structural framework, proteins also maintain proper pH and fluid balance. Finally, they keep your immune system strong, transport and store nutrients and can act as an energy source, if needed.
Explanation:
Hope this helped Mark BRAINLIEST!!!
Proteins help in cell structure formation, and cell transport, allow biochemical reactions, cell repair and also help in cell division.
What are cellular proteins?Proteins present in the cell are of various kinds. They are formed in the cell by the process of DNA transcription and translation.
The proteins formed in the cell then go on to perform various functions. The cellular proteins form the structure of the cell. They do that either by forming the cell membrane or the membrane of the organelles.
The cellular proteins also help in transport of nutrients. This transport is of two types. It can transport materials from inside to outside of the cell and vice versa. It can also transport materials inside the cell to other organelles.
Various biochemical reactions in the cell are possible because of the cellular proteins. The proteins formed in the cell are also used for cell repair and cell division.
Therefore, the various functions performed by the cellular proteins are cell structure formation, cell transport, allowing biochemical reactions, cell repair and help in cell division.

On the Bahamian island of Andros, mosquitofish populations live in various, now-isolated, freshwater ponds that were once united. Currently, some predator-rich ponds have mosquitofish that can swim in short, fast bursts; other predator-poor ponds have mosquitofish that can swim continuously for a long time. When placed together in the same body of water, the two kinds of female mosquitofish exhibit exclusive breeding preferences. Which type of reproductive isolation operates to keep the mosquitofish isolated, even when fish from different ponds are reunited in the same body of water
Answer:
The correct answer is - Behavioral isolation.
Explanation:
In the question, it is given that the mosquitofish of different habitat shows different behavior as per the availability of predators in the particular habitat. For instance, some mosquitofish can swim continuously for a long time in fewer predators area whereas predator-rich ponds have mosquitofish that can swim in short, fast bursts.
It is evident that they diverged from common species that isolated in different regions, their behavior got changed according to the presence of predators. Thus, the isolation is here, behavioral isolation.
how does greenhouse effect warm the earth?
Answer:
[tex]\color{Blue}\huge\boxed{Answer} [/tex]
The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. The absorbed energy warms the atmosphere and the surface of the Earth.

How does cellular respiration provide energy for life processes?
During cellular respiration animal cells combine oxygen with food molecules to release energy to live and function. Remember that cellular respiration produces carbon dioxide as a waste product. Animals use energy to grow, reproduce, and to function. They release the carbon dioxide into the air as a waste product.

Which of the following is NOT an example of natural selection?
A. Plants with thorns are less likely to be eaten by herbivores than other members of the same species that lack thorns.
B. Bacterial populations in hospitals develop resistance to drugs used to combat infection by them.
C. Scientists breed cows that give greater amounts of milk than their ancestors.
D. Fruit fly larvae with an enzyme to break down alcohol are better able to feed on fermenting fruit than those that lack the enzyme.
Answer:
The correct answer would be - C. Scientists breed cows that give greater amounts of milk than their ancestors
Explanation:
Natural selection is the process of adapting according to the new changes in condition and change accordingly to survive. So the individuals of organisms that are better and adapt faster to survive and reproduce better than others are the result of natural selection.
Plants developed thorns so they can be avoided by predators is the adaption and example of natural selection. Similarly, bacterial populations adapt and develop resistance to the drug. Fruit fly larva developed and adapt as well. Breeding cows for more amount of milk than ancestors by scientists is not natural selection.
which type of feature of Earth's crust does the diagram show (A) reverse fault (B) anticline (C) normal fault (D) syncline
its enviromental science
The figure illustrates the anticline of the earth's crust.
The correct option is B.
Anticline definition:A structural trap called an anticline is created when rock layers are folded into the shape of an arch. In an anticlinal trap, the rock layers were initially horizontally stacked until earth movement caused them to fold into such an arch-like structure known as an anticline.
What distinguishes an anticline?Rock formations called anticlines are folded structures with upward convex shapes. This means either anticline resemble a lowercase "n" or an uppercase "A" (remembering the shape of an anticline is as simple as saying "A is for Anticline"). They originate from horizontal and rather flat rock layers.
What is the crust of Earth?The outermost layer of a terrestrial planet is referred to as its "crust." The older, heavier continental crust and the denser, younger oceanic crust make up the majority of the Earth's crust. Plate tectonics provides information about the dynamic geology of the Earth's crust.

An animal ate a plant and digested sugars stored in the plant's leaves. The sugars provided energy
to the animal's cells. Describe which organelles the sugar molecules must have passed through.
Answer:
Mitochondria
Explanation: Mitochondria are oblong shaped organelles found in the cytoplasm of all eukaryotic cells. In plant cells, they break down carbohydrate and sugar molecules to provide energy, particularly when light isn't available for the chloroplasts to produce energy.

3.What are the functions of vacuoles, lysosomes, and the
cytoskeleton?
Answer:
In plant cells, vacuoles maintain water balance. Lysosomes break down excess or worn-out cell parts. The cytoskeleton is a structure that helps cells maintain their shape and internal organization, and it also provides mechanical support that enables cells to carry out essential functions like division and movement.
Explanation:
Storage, waste disposal and structural support are the functions of vacuoles, lysosomes, and the cytoskeleton.
The following are the roles of vacuoles, lysosomes, and the cytoskeleton: Vacuoles are membrane-bound organelles that can be found in the cells of fungus, protists, and plants. They serve a variety of purposes, such as: Vacuoles have the capacity to store a wide range of materials, including waste materials, pigments, water, and nutrients. They control the osmotic equilibrium and aid in maintaining turgor in plant cells. Vacuoles in plant cells can be used as a storage space for a variety of waste materials and poisons that are damaging to the cell. They keep these molecules apart and stop them from harming other cell components. Support for structure: In plant cells, the huge central vacuoles press on the cell wall to support structure and preserve the form of the cell. Lysosomes are membrane-bound organelles that can be found in cells.

what would happen to the ecosystem in the terrarium if it were a closed system for energy
Answer:
It would mimic the behavior of the earth's atmospheric atmosphere where you have a water cycle and sunlight which aids photosynthesis.
Explanation:
A terrarium is a glass container that can be covered and opened at will. It can be used to grow a plants using soil.
When it is sealed, water evaporates onto the body of the glass and runs down the sides of the glass only to be evaporated again and the same process happens over and over again.
Because the plants are in a glass container, they can still access sunlight for photosynthesis.
Sometimes the glass is opened up for maintenance. Maintenance here refers to the removal of algae that sometimes forms on the inner walls of the terrarium. Sometimes, there is also need to add water to the ecosystem in the terrarium given that the water inside usually escapes via evaporation over time.
