What its saying is:
for the chain chart: list a dangerous weather phenomonon you experienced and list words that specify the weather condition you experienced. For example:
you experienced: hurricane Catrina
Details: Had wrecked my house, was very scared then, other people were scared aswell, etc.
( Note that these details come in handy later for the next part.)
The next part wants you to organize the parts of the story kevin made about his hurricane. as a cheat key, its: 2, 1, 3, 4.
Drafting: Its asking you to make a sentence that describes how you felt during that time. You have to use the I before anything else in order to count for the grade if there is any grade given for this lesson.
The next part just wants you to write a story on teh event that you experienced, in this case the hurricane or other weather condition you have brought up.
Revising and proofreading:
were > was
think > thought
was > we
ever > remove this word
The last part just wants you to check off everything, like a grocery list.
Hope this helped!
In which situation might a gene pool contain an allele that causes a lethal
disease?
A. If the allele is in the mitochondria
B. If the allele is expressed after reproduction has occurred
C. If the allele is on the Y chromosome
D. If the allele is expressed in its dominant form
correct answer is B; if the allele is expressed after reproduction has occurred.
The situation in which a gene pool contain an allele that causes a lethal disease is: (B) If the allele is expressed after reproduction has occurred.
When the allele is expressed after reproduction has occurred, individuals carrying the lethal allele can reproduce and pass on the allele before the disease is expressed. Since the disease may not manifest until later in life or after reproduction has occurred, the allele can persist in the gene pool without being selected against. Over generations, the allele frequency can remain relatively stable, leading to the presence of the lethal allele in the gene pool.
An allele can be defined as a variant form of gene. Alleles can exist in different forms due to changes in the DNA sequence. These changes can be substitutions, deletions, insertions, or other types of genetic mutations.

What do you think humans and arthropods have in common?
Muscle and nerve cells are also alike in human beings and arthropods. Both have brains, hearts, digestive tracts, reproductive organs, and muscle groups that do more or less the same matters.
Arthropods are invertebrate animals having an exoskeleton, a segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. they may be outstanding by means of their jointed limbs and cuticle made from chitin, frequently mineralized with calcium carbonate.
Arthropods are beneficial for different meals that humans eat, especially thru the pollination of plants. greater than 100 food plants are pollinated via arthropods on a yearly basis. Bees, one of the foremost plant pollinators, also produce honey.
Arthropods also are invaluable to human beings, as they're used in many one-of-a-kind human-made products. Examples are: Bees produce honey and their honeycombs contain beeswax, broadly used for making candles, fixtures wax and polishes, waxed papers, antiseptics, and fillings for surgical uses.

A researcher places part of a plant cell in a beaker of water. She observes that the plant leaves release bubbles of gas when she shines a light on the beaker, and this is due to the plants going through photosynthesis, which is in Option B.
What is the product and the bubble formation in photosynthesis?The bubbles that are seen in water when plants are kept in light are actually oxygen bubbles. During photosynthesis, plants use sunlight, carbon dioxide, and water to produce glucose (sugar) and oxygen. The oxygen produced during photosynthesis is released into the surrounding environment as a waste product. When plants are submerged in water, this oxygen can accumulate and form bubbles. This process is called bubbling. The bubbles that are seen in the water are an indication that the plant is actively photosynthesizing and producing oxygen.
Hence, she observes that the plant leaves release bubbles of gas when she shines a light on the beaker, and this is due to the plants going through photosynthesis, which is in Option B.

Group of answer choices
True
False
Indicate whether a solution will have more OH– or H+ if the pH value of the solution
is 10.
The solution with a pH value of 10 will have more OH- ions.
In chemistry, pH is described as a scale that is specifically utilized to specify the basicity or acidity of an aqueous solution. The pH of different solutions are described as follows:
Acidic solution: If a solution has pH<7, then the solution is acidic and tend to have more H+ ions than OH- ions Neutral solution: The solution is neutral when pH=7 and the concentration of H+ and OH- ions are the same Basic solution: If a solution has pH>7, then the solution is Basic and tend to have more OH- ions than H+ ionsThus, in this case, pH>7 and thus we can conclude that the solution will have more OH- ions than H+ ions.

In which structure would you expect to find a chloroplast?
A. Blood cell from a dog
B. Cell from sunflower leaf
C. Human skin cell
D. Liver cell from a penguin
Answer:
b.cell from a sunflower leaf
The structure that can have chloroplast is the cell from sunflower leaf. The correct option is B.
What is chloroplast?Chloroplasts are chlorophyll-containing organelles found in plant cells; they are necessary for Earth life because photosynthesis occurs in chloroplasts.
Proplastids give rise to chloroplasts, as do chromoplasts, leucoplasts, as well as other plastids.
Chloroplasts are plant cell organelles that use photosynthetic energy to convert light energy into reasonably stable chemical energy.
They survive life on Earth by doing so. Chloroplasts also perform a variety of metabolic functions for plant cells, such as the generation of fatty acids and membrane lipids.
Chloroplasts are found in all green plants and algae. Chloroplasts can also be found in photosynthesis that don't appear green, such as giant kelp's brown blades or certain plants' red leaves.
Thus, the correct option is B.

If sunlight and a radio wave are both traveling through water, compare the speed of each wave. Explain how you know.
Answer:
Speed of both will be decreases when they travel through the medium of water.
Explanation:
Both sunlight and radio wave has the same speed in vacuum but both speed will be decreases when they travel through the medium of water because the consistency of water is more than air which make hard to travel for sunlight and radio wave. The speed of sunlight is slightly decreases but the radio wave can't go too far in the water and finally stops so we can say that sunlight can travel through water but radio wave none.

2. What fluvial landform is A?
Answer:
The landform marked with A is an ox-bow lake.
Explanation:
In the image, we can see a river and another fluvial landform right next to it. The river is meandering, moving through the plain in a zig-zag manner. The landform next to it has a half-circular shape, and it seems as it has been attached to the river until recently. In fact, the landform next to the river has been a part of the river until recently, but because of moving too far away from the base it became detached.
The landform in question is an ox-bow lake. This is a lake that has a short lifespan, and it usually has a half-circular shape, being just a few meters away from the river from which it formed. Initially, the ox-bow lake was actually part of the river and its meandering, but as the erosion was moving the water further and further away from the base of the river bed, the water was moving harder and harder, so naturally, the water moves in a direction where it is easier to do so. Little by little, the river starts to move in another direction, closer to its base, and the part of the meander that went too far away gets detached, thus forming an ox-bow lake.

What is the estimated age of Earth?
A.4.6x10^6
B.4.6x10^7
C.4.6x10^8
D.4.6x10^9
Answer:
D: 4.6 x [tex]10^{9}[/tex]
Explanation:
4.6 x 10^{9} = 4,600,000,000
Earth is approximately, 4.6 billion = 4,600,000,000 = 4.6 x 10^{9}
The estimated age of Earth is 4.6x10⁹ years (D).
Scientists estimate the age of Earth through various methods, including radiometric dating of rocks and minerals. By analyzing the isotopes present in rocks and minerals, scientists can determine the decay rates of radioactive isotopes and calculate the time since the formation of those rocks.
Based on extensive studies and evidence, the current estimated age of Earth is approximately 4.6 billion years (4.6x10^9 years). This estimation is supported by multiple lines of evidence, including radiometric dating of rocks from different geological formations, lunar samples brought back from the Moon, and meteorites.
The age of 4.6 billion years is consistent with the age of the oldest rocks found on Earth's surface and the ages of the Moon and meteorites, which are believed to have formed around the same time as Earth. These dating methods provide a reliable framework for understanding Earth's geological history and the processes that have shaped our planet over billions of years.
It's important to note that scientific estimates and understanding of Earth's age continue to evolve as new evidence and research emerge. However, the current consensus among scientists is that the age of Earth is approximately 4.6 billion years, as indicated by extensive geological and radiometric dating studies.
