The top left, would be light energy from the sun, while the top of the circle would be living beings. Think about it just like plants that that gain energy from the sun through photosynthesis. Then the bottom of the circle would be nonliving beings, either decomposed plants or animals that bring nutrients to soil, or dead ones that we eat. This cycles through until the energy is rereleased through heat. Therefore the top right would be heat energy, every living thing on earth creates gradual amounts of heat. Imagine going for a run, you'll probably be hotter afterwards right? I know it's not the most scientific answer but its 100% right.

a recipe calls for 1 cup of sugar and 1/2 cup of flour.Zoe uses 1 cup of salt and 1/2 cup of flour.
which kind of mutation is best modeled by zoes version of the recipe
Answer:
Substitution
Explanation:
Given the information in the question substitution seems like the most appropriate answer. Zoe used 1 cup of slat rather than 1 cup of sugar, she substituted sugar for salt.
Insertion is wrong because Zoe did not add another ingredient, there is still only 2 ingredients.
Transition is wrong because, given the information, because the state(liquid or solid) of the ingredients has not changed. Zoe is still use dry ingredients per say.
And beneficial also seems to be wrong because we don't know if using salt instead was beneficial to the recipe or to Zoe.

A cellular biologist is curious as to why a protein is not being expressed even though they placed the needed transcription factors and ribosomes allowing for the transcription and translation of the protein to take place in the cell. They look at the mRNA and find it is being translated and exported to the nucleus but ribosomes are not binding to it. After careful observation she finds out that the mRNA is missing its _____________. Without this of course ribosomes would have an issue binding to the mRNA and inducing translation.
Answer:
5' cap
Explanation:
In eukaryotes, the 5′ end of mRNA in eukaryotes is modified (i.e., capped) with a guanine nucleotide which is connected to mRNA via 5´→ 5´ triphosphate linkage. The five-prime cap (5′ cap) is denoted as 7-methylguanylate cap (m7G) because guanosine is methylated at the 7 position by a 7-methyl transferase. This cap acts to protect the mRNA from degradation and also is required during translation initiation in order to mediate a process known as ribosome recruitment. This process (ribosome recruitment) occurs through the association of the 43S preinitiation complex (composed of the small ribosomal subunit, eIF1, eIF1A, eIF2, eIF3 and eIF5 factors) with the 5' capped mRNA. After mRNA binding, the 43S preinitiation complex is ready to scan an initiation codon in order to start the translation.

which type of specialized cells would be found in an animal’s neuvous system?
The type of specialized cells would be found in an animal’s nervous system are the cells that transmit signals around the body. The correct option is D.
What is the nervous system?The nervous system is the part of an animal's body that controls behavior and sends messages to other parts of the body. It is divided into two components in vertebrates: the central nervous system (CNS) and the peripheral nervous system. The CNS houses the brain and the spinal cord.
Neurons are specialized cells found in animals. These cells are classified as sensory neurons, interneurons, or motor neurons based on their function. They transmit signals from the body to the brain and from the brain to the body parts.
Therefore, the correct option is D. Cells that can transmit signals around the body.

Cancer cells are essentially cells out of control. They continuously go through Mitosis without stopping causing them to crowd other cells and eventually growing on top of each other forming a lump commonly referred to as a tumor. Based on your knowledge of mitosis what is one way you could develop a drug to treat cancer?
Include in your answer a detailed explanation of what you would do and why (5pts) also include labeled diagrams with your solution (5pts).
Answer:
Introduction
Does cell cycle control matter? If you ask an oncologist – a doctor who treats cancer patients – she or he will likely answer with a resounding yes.
Cancer is basically a disease of uncontrolled cell division. Its development and progression are usually linked to a series of changes in the activity of cell cycle regulators. For example, inhibitors of the cell cycle keep cells from dividing when conditions aren’t right, so too little activity of these inhibitors can promote cancer. Similarly, positive regulators of cell division can lead to cancer if they are too active. In most cases, these changes in activity are due to mutations in the genes that encode cell cycle regulator proteins.
Here, we’ll look in more detail at what's wrong with cancer cells. We'll also see how abnormal forms of cell cycle regulators can contribute to cancer.
What’s wrong with cancer cells?
Cancer cells behave differently than normal cells in the body. Many of these differences are related to cell division behavior.
For example, cancer cells can multiply in culture (outside of the body in a dish) without any growth factors, or growth-stimulating protein signals, being added. This is different from normal cells, which need growth factors to grow in culture.
Cancer cells may make their own growth factors, have growth factor pathways that are stuck in the "on" position, or, in the context of the body, even trick neighboring cells into producing growth factors to sustain them^1

Diagram showing different responses of normal and cancer cells to growth factor presence or absence.
Normal cells in a culture dish will not divide without the addition of growth factors.
Cancer cells in a culture dish will divide whether growth factors are provided or not.
Cancer cells also ignore signals that should cause them to stop dividing. For instance, when normal cells grown in a dish are crowded by neighbors on all sides, they will no longer divide. Cancer cells, in contrast, keep dividing and pile on top of each other in lumpy layers.
The environment in a dish is different from the environment in the human body, but scientists think that the loss of contact inhibition in plate-grown cancer cells reflects the loss of a mechanism that normally maintains tissue balance in the body^2

squared.
Another hallmark of cancer cells is their "replicative immortality," a fancy term for the fact that they can divide many more times than a normal cell of the body. In general, human cells can go through only about 40-60 rounds of division before they lose the capacity to divide, "grow old," and eventually die^3

Cancer cells can divide many more times than this, largely because they express an enzyme called telomerase, which reverses the wearing down of chromosome ends that normally happens during each cell division^4

start superscript, 4, end superscript.
Cancer cells are also different from normal cells in other ways that aren’t directly cell cycle-related. These differences help them grow, divide, and form tumors. For instance, cancer cells gain the ability to migrate to other parts of the body, a process called metastasis, and to promote growth of new blood vessels, a process called angiogenesis (which gives tumor cells a source of oxygen and nutrients). Cancer cells also fail to undergo programmed cell death, or apoptosis, under conditions when normal cells would (e.g., due to DNA damage). In addition, emerging research shows that cancer cells may undergo metabolic changes that support increased cell growth and division^5

C. Organisms evolve over time due to changes in heritable physical
characteristics.
D. If a person takes at least one vitamin per day, then it will reduce a
person's level of tiredness.
HELP PLEASE!
Answer: Organisms evolve over time due to changes in heritable physical characteristics.
Explanation:
There are a few things to look for when distinguishing between a nonscientific theory and a valid scientific theory. One thing to consider is if there are any published literature, experimental studies, and data available to support the theory. Most scientific theories have data and information tied to them. Another factor to examine is who has developed the theory. A scientific theory will always be supported by evidence with large quantities of data and testing. An example of a scientific theory is the theory of evolution, which observes changes in heritable physical traits over time in an organism. A hypothesis might be that all organisms evolve at the same rate.
Organisms evolve over time due to changes in heritable physical characteristics is an example of a scientific theory known as evolution. Thus, option C is correct.
What is evolution?Evolution is the scientific theory that explains that "a change in the characteristics of biological populations over next generations.
According to scientists RNA is the first existing molecule on earth that replicate by itself and the process of evolution lead to advanced forms of life.
These characteristics are easily trasfered from one generation to other generation.
Therefore, Organisms evolve over time due to changes in heritable physical characteristics is an example of a scientific theory known as evolution. Thus, option C is correct.
