how are proteins made in animals and humans
Answer:
Through protein synthesis of course...
Explanation:
DNA and RNA do many steps such as translation, transcription, and more to form protein codons and code them into amino acids. Then, thousands of amino acids are oined together to make proteins, which regulate body function and catalyze chemical reactions (enzymes). Ribosomes are also involved in this action. To make proteins, nitrogen is needed for the plant to use, and that comes mainly from nitrate ions in the soil, and gets into the plant by active transport.
The carrying capacity of an ecosystem will most likely become unbalanced when?
Answer:
In a population at its carrying capacity, there are as many organisms of that species as the habitat can support. ... If resources are being used faster than they are being replenished, then the species has exceeded its carrying capacity. If this occurs, the population will then decrease in size.
Explanation:
When resources are depleted faster than they are replenished, the species has reached its carrying capacity. If this happens, the population will shrink in size.
What is carrying capacity?Carrying capacity is defined as the average population size of a species in a given habitat.
Environmental factors such as adequate food, shelter, water, and mates limit the species population size. If these requirements are not met, the population will decline until the resources recover.
Carrying capacity, or the maximum number of people that an environment can support over time without destroying or degrading it, is determined by three key factors: food availability, water availability, and space.
Carrying capacity is the maximum number, density, or biomass of people that a given area can sustainably support.
This is likely to change over time and is influenced by environmental factors, resources, and the presence of predators, disease agents, and competitors.
Thus, any disturbance in these factors can lead to an unbalanced carrying capacity.

The warming of the atmosphere by the trapping of heat being radiated to space is called
a)condensation
b)evaporation
c)the greenhouse effect
d)radiation
Answer:
The greenhouse effect is a process that occurs when gases in Earth's atmosphere trap the Sun's heat. This process makes Earth much warmer than it would be without an atmosphere. Solar energy absorbed at Earth's surface is radiated back into the atmosphere as heat. As the heat makes its way through the atmosphere and back out to space, greenhouse gases absorb much of it.

Name and describe the five types of active transport systems.
Answer:
Please Mark as Brainliest. Please!!!!!!!!!!
Explanation:
Definition
Active transport is the process of transferring substances into, out of, and between cells, using energy. In some cases, the movement of substances can be accomplished by passive transport, which uses no energy. However, the cell often needs to transport materials against their concentration gradient. In these cases, active transport is required.
Active transport requires energy to move substances from a low concentration of that substance to a high concentration of that substance, in contrast with the process of osmosis. Active transport is most commonly accomplished by a transport protein that undergoes a change in shape when it binds with the cell’s “fuel,” a molecule called adenosine triphosphate (ATP).
For example, one type of active transport channel in the cell membrane will bind to the molecule it is supposed to transport – such as a sodium ion – and hold onto it until a molecule of ATP comes along and binds to the protein. The energy stored in ATP then allows the channel to change shape, spitting the sodium ion out on the opposite side of the cell membrane. This type of active transport directly uses ATP and is called “primary” active transport.
Another type of active transport is “secondary” active transport. In this type of active transport, the protein pump does not use ATP itself, but the cell must utilize ATP in order to keep it functioning. This will be explained in more depth in the section on Symport Pumps below.
Lastly, active transport can be accomplished through processes called endocytosis and exocytosis. In exocytosis, a cell moves something outside of itself in large quantities by wrapping it in a membrane called a vesicle and “spitting out” the vesicle. In endocytosis, a cell “eats” something by wrapping and re-forming its membrane around the substance or item.
Each type of active transport is explained in more detail below.
Types of Active Transport
Antiport Pumps
Antiport pumps as an example of active transport
Active transport by antiport pumps
Antiport pumps are a type of transmembrane co-transporter protein. They pump one substance in one direction, while transporting another substance in the opposite direction. These pumps are extremely efficient because many of them can use one ATP molecule to fuel these two different tasks.
One important type of antiport pump is the sodium-potassium pump, which is discussed in more detail under “Examples of Active Transport.”
Symport Pumps
Symport pumps take advantage of diffusion gradients to move substances. Diffusion gradients are differences in concentration that cause substances to naturally move from areas of high to low concentration.
In the case of a symport pump, a substance that “wants” to move from an area of high concentration to low concentration down its concentration gradient is used to “carry” another substance against its concentration gradient.
One example of a symport pump – that of the sodium-glucose transport protein – is discussed below under “Examples of Active Transport.”
Sympoter pump as an example of active transport
Active transport by symporter pumps
Endocytosis
In the third type of active transport, large items, or large amounts of extracellular fluid, may be taken into a cell through the process of endocytosis.

A scientist crossed two fruit flies in a lab. She was studying the transmission of the alleles that affect wing shape. The dominant allele, C, is the allele for curly wings, and the recessive allele, c, is the allele for straight wings. She knew that one of the parent flies was heterozygous and had curly wings (Cc). Half of the offspring from the cross had curly wings, and the other half had straight wings. Identify the genotype and phenotype of the second parent fly. State the evidence that supports your response.
Answer:
The other fly would have to be a cc
Explanation:
To do this, you can use the square method, one Cc's on the top and one side a cc, when you cross these it gives you Cc, Cc, and cc, cc. Half and half.
Hope this helped!
The other parent was cc.
Genes often occur in pairs. Genes are units of inheritance located in the chromosomes. The pairs in which genes occur are called alleles. In a given pair of alleles, one gene is dominant and the other is recessive.
In this case, the dominant gene is for curly wings and the recessive gene is for straight wings. If one parent is Cc , the other parent must be cc causing half of the offspring from the cross to have curly wings, and the other half to have straight wings.

What does lemon juice, snake venom and cyanide have in common?
Answer:
enzymes are protein molecules that act as catalysts, speeding up chemical reactions without themselves getting used up. Each enzyme will only speed up a specific reaction, for example, catalase will speed up the decomposition of hydrogen peroxide into water and oxygen but it will not speed up the breakdown of starch into glucose. Enzymes (e.g. catalase) have active sites with specific shapes that bind to the substrate molecule (e.g. hydrogen peroxide) forming an enzyme-substrate complex. The enzyme-substrate complex then breaks down into the enzyme and product, allowing the enzyme to go on and react with another substrate molecule. Temperature and pH affect enzyme function because they can change the shape of the enzyme’s active site, preventing it from binding to the substrate, just as a broken lock will no longer fit the key. When the shape of an enzyme changes we call this denaturation. Any factor that increases the frequency of collisions between enzymes and substrates (increasing concentration, surface area or temperature) will increase the rate of reaction.
