Answer:
Global warming is defined as the environmental issue that leads to long term heating of the earth due to human activities such as burning of fossil fuels.
1. Arctic areas are facing huge challenges due to global warming that includes rising sea levels, rapid melting of ice, loss of fish stocks, birds and marine mammals, and changes in climate patterns.
2. Measures that help to deal with the problem are reduction in the use of hydrofluorocarbons, cutting emissions of black carbon, methane, reduce overfishing, and reduction of industrial waste.
3. If there will be no measure taken to reverse the problem of global warming in the Arctic ecosystem, it will cause flood and tsunami in the nearby continents due to the rapid melting of ice, changes in climate patterns, and lead to the extinction of many marine animals.
4. Reduction of industrial waste is the most important measure to pursue because industrial waste contributes most of the greenhouse gases and causes air pollution, land pollution, water pollution, and nuclear pollution. So reduction is industrial waste will reduce the emission of harmful gases in the environment that can reduce the impact of global warming.

Witch of the following would introduce a bias into an experiment?
A. Publishing your experimental results in a scientific journal.
B. Allowing other scientist to repeat and verify your experimental results.
C. Using a computer to record and store your data.
D. Discarding data that does not fit with your personal expectations.
Answer:
D. Discarding data that does not fit with your personal expectations.
Explanation:
One of the ways in which bias can be introduced into an experiment is by discarding data that does not fit with one's personal expectations.
Bias in an experiment is the process whereby scientists alter the results of their experiment to achieve their own expected results.
Anomalous values defined by one's expectation can make an experiment highly biased. A scientist is supposed to be objective in their experimental approaches.FIRST GETS BRAINLEIST!!

Genetic variation is the difference in DNA among individuals or the differences between populations. There are multiple sources of genetic variation, including mutation and genetic recombination.
Explanation:
Explanation:
Genetic variation refers to diversity in gene frequencies. Genetic variation can refer to differences between individuals or to differences between populations. Mutation is the ultimate source of genetic variation, but mechanisms such as sexual reproduction and genetic drift contribute to it as well.

Answer:
With the boost in warmer weather and excess water, populations will boom
Explanation:
Yabbies will do best at a water temperature of between 12°C and 20°C but they will tolerate water that is a little colder or warmer. Complete immersion in water is not essential for life for the yabby. If its gills are kept moist (humid air is sufficient), it can absorb oxygen from the air and survive for many days out of water. To breed, however, it must be in water. With the water needed for breading and warmer weather used for breeding, population numbers for the Yabbies should rise.
Alyssa is observing two cells, X and Y. Each cell is from either a plant or an animal. She records some of her observations in a chart.
Cell Observations
Cell X Cell Y
has lysosomes lacks lysosomes
lacks a cell wall has endoplasmic reticulum
has ribosomes has a nucleus
Which additional observation will Alyssa most likely make?
Cell X has a cell membrane, and Cell Y does not.
Cell Y has a cell membrane, and Cell X does not.
Cell Y has a larger vacuole than Cell X.
Cell X has a larger vacuole than C
Answer:
Cell Y has a larger vacuole than cell X
Explanation:
Cell Y is the plant cell, only plant cells have a tough and rigid cell wall, animal cells do not. The observation that Cell X lacks a cell wall as well as having lysosomes is indication that Cell X is an animal cell. The answer that Cell Y has a larger vacuole is true because plant cells need to store more water and nutrients than animal cells and will have a much larger vacuole.

13. In a forest, why do you rarely see young pine trees growing under a broad-leaved tree, such as a maple? If broad-leaved trees eventually take over a forest as pines die off, how does that affect other organisms living in the forest? How does it affect this forest ecosystem?*
Answer:/Explanation:
Broad leaved trees would block the sunlight due to the size of their leaves. This would reduce the amount of sunlight that the pine tree could absorb, and would therefore inhibit its ability to efficiently perform photosynthesis. This would reduce the amount of food it could synthesise, and interfere with its growth and reproduction.
Without pine trees, the diversity of the ecosystem would be reduced. Several organisms rely on pine seeds and leaves as a food source. In the absence of pine trees, competition for other food sources could increase, and certain birds, squirrels etc. could die off.
Pine trees are also a habitat for many birds and small creatures. Without these trees, these animals could struggle to find efficient shelter.

HELP YALL I NEED IT QUICKKKKK Hybrid seeds are deliberately crossbred for particular traits, such as growth pattern or disease resistance. They have been hand-pollinated and are patented, often sterile, and genetically identical within food types. These plants are usually grown in a monocultural environment and are cultivated for mass production and sale. They must be sturdy to withstand mechanical picking and cross-country shipping. They do not compare to the quality and taste of heirloom plants, but they do produce large, healthy fruit that appeals to most shoppers. Unlike heirloom seeds, if one saves a hybrid seed, one will not get the same plant again.
Which statement can be removed and not affect the excerpt’s reliability?
Answer:
Unlike heirloom seeds, if one saves a hybrid seeds, one will not get same plant again.
Explanation:
Hybrid seeds they are cross pollinated. It is the main contributor in agriculture.

Which of the following is Bernoulli's principle?
1. As the speed of a moving fluid increases the pressure within the fluid decreases.
2. As the speed of a moving fluid decreases the pressure within the fluid increases.
3. As the speed of a moving fluid increases the pressure within the fluid increases.
4. As the speed of a moving fluid decreases the pressure within the fluid decreases.
Answer:
1. As the speed of a moving fluid increases the pressure within the fluid decreases.
Explanation:
Hope this helps!
The Bernoulli's principle is applied when the speed of a moving fluid increases as the pressure within the fluid decreases. Thus, the correct option is 1.
What is Bernoulli's Principle?The inverse relationship between pressure and speed at a point in any fluid is called Bernoulli's principle. Bernoulli's principle states that "At points along a horizontal streamline, higher pressure regions have lower fluid speed and lower pressure regions have higher fluid speed".
Bernoulli's principle is based on the law of conservation of energy. The total energy (pressure energy, potential energy and kinetic energy) of a flowing liquid under constant pressure at different points differ.
Therefore, the correct option is 1. With the increase in speed, the pressure within the fluid decreases.

Cytokinesis – division of the cytoplasm resulting in two identical d_______________ cells.
Answer: daughter
Explanation: Cytokinesis results in the division of cytoplasm in a parental cell, creating 2 identical daughter cells.
Hope this helps!
Cytokinesis, the division of the cytoplasm resulting in two identical daughter cells, is caused by the mitosis process, as here the two daughter cells get an equal amount of the genetic contents.
What is the significance of cytokinesis in mitosis?It is very important in mitosis because it aids in the division of two cells from one cell during the cell division process and results in the formation of two genetically identical daughter cells; without cytokinesis, the chromosomes would remain in the same cell, resulting in mutation as multinucleated cells are formed in such a process.
Hence, cytokinesis, the division of the cytoplasm resulting in two identical daughter cells, is caused by the mitosis process, as here the two daughter cells get an equal amount of the genetic contents.
