Label this illustration with the maximum electron capacity for each energy level:
The maximum electron capacity for each energy level is given by 2n^2.
According to the Bohr model of the atom, electrons are arranged in energy levels in an atom. The energy levels are arranged in increasing order as we go farther away from the nucleus.
The maximum electron capacity for each energy level is given by 2n^2. Hence, when;
n = 2, the maximum electron capacity is 2 electrons
n =2, the maximum electron capacity is 8 electrons
n=3, the maximum electron capacity is 18 electrons
n = 4, the maximum electron capacity is 32 electrons

Reflect again on competitive relationships. What would happen if the factor became more abundant or unrestricted?
Answer:
If a factor became more abundant, there would still be competition, but there would be less. *See below for an explanation that makes a little more sense (No, I am not sending you a link)*
Explanation:
In every ecosystem, there is competition. The competition could be for mates, food, shelter... anything, really. However, when those resources become more prevalent, there still might be competition, but there would probably be less than before. Let's try an example: Imagine that we were about to endure an incredibly strong hurricane. If you have ever prepared for a hurricane, you would most likely understand that if you get to the stores too late, there most likely wouldn't be much to choose from. Everything would be cleared from the shelves. Now there is competition for resources such as food and water that we would need to spend several days without power and electricity. However, if the shelves were to restock and everything is replenished, there wouldn't need to be any fighting over toilet paper, right? The same happens with plants and animals. If there is a sudden abundance of resources, they no longer need to compete so aggressively. *You might also see an increase in population, too*
Sorry, I gave such a wordy answer. I just really, really, really want you to understand so you good grades. I hope you understand :) :) :)
If the factor became more abundant or unrestricted, the competition will definitely increase among the organisms in the ecosystem.
What is Competition?Competition may be defined as a type of species interaction that significantly affects both species negatively because both species here compete for the same resources. It is a type of negative-negative interaction.
According to the context of this question, if a factor or resource remarkably increases its abundant and became unrestricted, it will definitely lead to the process that increases the competition between two or more species. This is because it allows the organisms to move away from their original niches.
Therefore, if the factor became more abundant or unrestricted, the competition will definitely increase among the organisms in the ecosystem.

how can you explain what you know about the heavily muscled cows with what you have learned about mutations, patterns of inheritance, incomplete dominance, sexaul reproduction, selective breeding and transferring of genetic information?
Myostatin (GDF-8) is a member of the transforming growth factor β superfamily of secreted growth and differentiation factors that is essential for proper regulation of skeletal muscle mass in mice. Here we report the myostatin sequences of nine other vertebrate species and the identification of mutations in the coding sequence of bovine myostatin in two breeds of double-muscled cattle, Belgian Blue and Piedmontese, which are known to have an increase in muscle mass relative to conventional cattle. The Belgian Blue myostatin sequence contains an 11-nucleotide deletion in the third exon which causes a frameshift that eliminates virtually all of the mature, active region of the molecule. The Piedmontese myostatin sequence contains a missense mutation in exon 3, resulting in a substitution of tyrosine for an invariant cysteine in the mature region of the protein. The similarity in phenotypes of double-muscled cattle and myostatin null mice suggests that myostatin performs the same biological function in these two species and is a potentially useful target for genetic manipulation in other farm animals.
The transforming growth factor β superfamily encompasses a large group of secreted growth and differentiation factors that play important roles in regulating development and tissue homeostasis (1). We have recently described a member of this family, myostatin, that is expressed specifically in developing and adult skeletal muscle and functions as a negative regulator of skeletal muscle mass in mice (2). Myostatin null mice generated by gene targeting show a dramatic and widespread increase in skeletal muscle mass. Individual muscles in myostatin null mice weigh 2- to 3-fold more than those of wild-type mice, primarily due to an increased number of muscle fibers without a corresponding increase in the amount of fat. To pursue potential therapeutic and agricultural applications of increasing muscle mass by inhibition of myostatin activity, we have been characterizing myostatin in animals other than mice. Here we report that the myostatin gene is highly conserved among vertebrate species and that two breeds of cattle that are characterized by increased muscle mass (double muscling), Belgian Blue (3) and Piedmontese (4), have mutations in the myostatin coding sequence. These results demonstrate that the function of myostatin has been highly conserved among vertebrates. hope it helps

Memories of a Memory
Have you ever witnessed something amazing, shocking or surprising and found when describing the event that your story seems to change the more you tell it? Have you ever experienced a time when you couldn't really describe something you saw in a way that others could understand? If so, you may understand why some experts think eyewitness testimony is unreliable as evidence in scientific inquiries and trials. New insights into human memory suggest human memories are really a mixture of many non-factual things.
First, memory is vague. Imagine your room at home or a classroom you see every day. Most likely, you could describe the room very generally. You could name the color of the walls, the floors, the decorations. But the image you describe will never be as specific or detailed as if you were looking at the actual room. Memory tends to save a blurry image of what we have seen rather than specific details. So when a witness tries to identify someone, her brain may recall that the person was tall, but not be able to say how tall when faced with several tall people. There are lots of different kinds of "tall."
Second, memory uses general knowledge to fill in gaps. Our brains reconstruct events and scenes when we remember something. To do this, our brains use other memories and other stories when there are gaps. For example, one day at a library you go to quite frequently, you witness an argument between a library patron and one of the librarians. Later, when telling a friend about the event, your brain may remember a familiar librarian behind the desk rather than the actual participant simply because it is recreating a familiar scene. In effect, your brain is combining memories to help you tell the story.
Third, your memory changes over time. It also changes the more you retell the story. Documented cases have shown eyewitnesses adding detail to testimony that could not have been known at the time of the event. Research has also shown that the more a witness's account is told, the less accurate it is. You may have noticed this yourself. The next time you are retelling a story, notice what you add, or what your brain wants to add, to the account. You may also notice that you drop certain details from previous tellings of the story.
With individual memories all jumbled up with each other, it is hard to believe we ever know anything to be true. Did you really break your mother's favorite vase when you were three? Was that really your father throwing rocks into the river with you when you were seven? The human brain may be quite remarkable indeed. When it comes to memory, however, we may want to start carrying video cameras if we want to record the true picture.

Which examples are an abiotic factor of an ecosystem? select all that apply
Answer:
the last three
Explanation:
Abiotic is non living organisms or things.
The water animals drink is one answer.
The second is the caves used for protection from predators.
The third is the amount of water vapor in the air.
Abiotic factors in an environment include such items as sunlight, temperature, wind patterns, and precipitation. Therefore to be abiotic an organism must be not associated with or derived from living organisms.

Dermal tissues in plants and epithelial tissues in animals are similar is that they offer protection. The correct option is A.
What is epithelial tissues?The epithelium is a type of body tissue that forms the covering on all of your body's internal as well as external surfaces, lines body cavities and hollow organs, and is the chief tissue in glands.
The primary function of different tissues varies depending on their location and cell type. Stratified epithelium and goblet cells typically form protective barriers.
The plant epidermis, the outer layer of tissue that surrounds the primary body of vascular plants, is referred to as dermal tissue.
The roots, stems, leaves, flowers, fruits, and seeds are all included. The dermal layer lacks chloroplasts and is typically made up of a single layer of tightly packed cells.
Thus, the correct option is A.
