Include at least 3 ways that illegal fishing impacts the environment and descriptions
Answer:
Goodluck. I hope I helped
Explanation:
Oceans support the livelihoods of an estimated 520 million people who rely on fishing and fishing related activities, and 2.6 billion people who depend on fish as an important part of their diet. But Illegal fishing is threatening the food supply of coastal communities as fish populations decline due to overfishing in areas fishers are not permitted to access. Addressing illegal fishing will positively contribute to the equitable growth and empowerment of the people who rely on oceans for food and income.

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.

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

cubed.
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

A father sheep has curly wool while a mother sheep has straight wool. Which of these statements explains why one of their baby lambs has curly wool?
Answer:
This means that the baby sheep received the same set of genes as the father sheep giving it curly wool.
Explanation:
This means that the baby sheep received the same set of genes as the father sheep giving it curly wool.
OR if the baby sheep received a mixed set of genes , one from father , the other from mother , the gene of the father is dominant over the gene of the mother and it has given the baby sheep curly wool.
During fertilization the baby must have received the same set of genes as those of its father. If the baby has received a mixed set of genes then the genes of the father are dominant over the genes of the mother resulting in curly wool.
The fathers gene may be dominant due to environmental circumstances or other factors.
Answer:
Explanation:The baby lamb inherited its copies of the gene for wool shape from its father and not from its mother. Just like its father’s genes, those genes instruct for proteins that connect in ways that make its wool curly.

Answer:
First a glucose molecule enters the body cell, and then a glucose molecule is broken down in the cytoplasm. Then, oxygen is used to break down smaller molecules, smaller molecules enter the mitochondrion. Finally, a large amount of energy is released.
Explanation:
After you ate an energy bar full of glucose, the molecules will first enter the cells, prepare to be broken down in the first site, cytoplasm. And now, oxygen takes a part in it, continue to break it down. The smaller molecules now enter the energy source of a cell, which is mitochondrion, the energy will be released here.

Which statement best describes the relationship between ocean co2 and ph
Acidity rises and pH falls as carbon dioxide levels rise. The correct option is C.
What is ocean pH?A change in the characteristics of ocean water known as ocean acidification may be detrimental to plants and animals.
Scientists have noticed that the ocean's acidity is rising as a result of the water's absorption of atmospheric carbon dioxide.
Ocean acidification is the decrease in the ocean's pH level. The average pH of the ocean's surface fell from about 8.25 to 8.14 between 1751 and 2021.
Ocean water is more basic than drinking water because it is resistant to pH fluctuations due to the presence of various weak acids and their corresponding bases, or buffers.
The ocean is regarded as having a pH that is slightly alkaline. Acidity and pH both drop when carbon dioxide levels rise.
Thus, the correct option is C.
