Explain how parts of a whole system contribute to the function of a whole system?
Every organ system is made up of parts that contribute to the functions of the whole system.
How do parts of the system contribute to the function of a whole system?The human body is made up of many parts that have specific functions that come together to make up the whole organ system. Scientists divide them into different parts and different organ systems to better understand the individual functioning of the specific parts.
A body system is made up of body parts that work together to carry out a particular function. For example, the integumentary system that consists of skin, hair and nails that integrate together to carry out the function of protecting the body.
Another example is that of the immune system that is made up of complex organs, tissues and cells like the WBCs that form a network among each other to carry out the function of recognizing antigens and destroying them to keep infections at bay.
Two or more body systems also work together to carry out a certain function. For example the respiratory system and circulatory system come together to provide oxygen to the cells of the body and remove carbon dioxide.
This is how parts of the whole system contribute to the function of the whole system.

Which of the following is something you should do after severe weather occurs?
Clean up flood waters.
Cleaning up will always be the step after the storm. Assuming they're talking about a hurricane, then the flood waters would need to be cleaned up. Besides for the last choice (which is utterly ridiculous!), those should be before and during the storm.
Depending on where you live and what kind of sever weather you encounter, a safety plan for you and your family is a must. You should always know where you can go to be safe from the elements and what to do during severe weather.
During the storm, stay away from windows. This pertains to all weather, including those with wind and lightning. Wind could blow debris that could possibly shatter glass and hurt you or others. With lightning, if it strikes the window, it will shatter it, merely from the heat of the contact.

Oxygen and carbon combine to form different compounds. What type bond is formed between these two atoms?
options:
hydrogen
ionic
covalent
Answer:
C.) Covalent
Explanation:
Oxygen and carbon are both nonmetals.
A.) is incorrect because hydrogen bonds are only formed between hydrogen and either oxygen, nitrogen, or fluorine.
B.) is incorrect because ionic bonds form between nonmetals and metals. In this situation, you have two nonmetals.
C.) is correct because covalent bonds are formed between two nonmetals. A covalent bond will form because oxygen and carbon are nonmetals.
Answer:
Covalent
Explanation:
A covalent bond is formed when two non metals form, which means that's the answer. For the record, for hydrogen bonding Hydrogen obviously has to be present, and an ionic bond occurs between a metal and a nonmetal

Which represents the cross between parent plants if one is heterozygous and has yellow-colored pods and the other is homozygous and has green-colored pods? yy ´ yy yy ´ yy yy ´ yy yy ´ yy
The cross between parent plants if one is heterozygous and has yellow-colored pods and the other is purebred and has green-colored pods is Yy×yy.
What is Heterozygous?Heterozygous may be defined as the existence of two distinguishable alleles at a distinct gene locus.
In this condition, Yellow is dominant over green i.e. Y>y. Heterozygous means the existence of two distinguishable alleles at a distinct gene locus. So, the genotype of one parent is Yy, while the other parent is purebred and has green-colored pods. Hence, the genotype is yy.
Therefore, the cross between parent plants if one is heterozygous and has yellow-colored pods and the other is purebred and has green-colored pods is Yy×yy.

How the dorsal/ventral pattern is initially established in drosophila development
The dorsal/ventral pattern is initially established in drosophila development by the gradient of a transcription factor called dorsal protein.
What do you mean by Dorsal protein?Dorsal proteins are synthesized after fertilization, when dorsal is translated, it forms a complex with a protein known as cactus in the cytoplasm.
The dorsal/ventral axis in the Drosophila is determined by morphogenesis which is established by 12 maternal effect genes along with the dorsal and cactus.
Therefore, the dorsal/ventral pattern is initially established in drosophila development by the gradient of a transcription factor called dorsal protein.

Sayid listed some characteristics of waves in a chart. Part of his chart is shown.
A 1-column table with titled Characteristics of Waves. The column labeled Electromagnetic Waves has entries travel in straight lines, move only through matter, involve interactions with magnetic fields.
Which of these would correct Sayid's error?
Change the heading of the chart to “Mechanical.”
Replace “travel in straight lines” with “move in curved paths.”
Add “move due to particles bumping into each other” to the chart.
Change “move only through matter” to “move through space and matter.”
Answer:
Change “move only through matter” to “move through space and matter.”
Explanation:
Electromagnetic wave like light can travel thru both space and matter. Ever tried to shine a flash light thru a water bottle? The light passes thru the water and the bottle (both are types of matter: liquid and solid) and reaches the other side.
Ever see Suns ray enter your eyes? The light travels thru the vast empty space (our solar system) to reach earth.
Thus, electromagnetic waves can move thru both space and matter.
Electromagnetic waves have the ability to move through matter as well as through space. So the correct option is Option D.
What are the characteristics of Electromagnetic waves?An electromagnetic wave is a type of radiation that travels through space. Electromagnetic waves form when an electric field meets a magnetic field.
Electromagnetic waves do not require molecules to travel. Unlike sound waves, which travel through matter by smashing molecules together, electromagnetic waves cannot travel through a vacuum such as space. Instead, they can travel through the air, solid matter, and even space. This makes electromagnetic waves very useful for many technologies.
There are many different types of waves in the electromagnetic spectrum, ranging from radio waves that are as long as a building to gamma rays that are smaller than a nucleus of an atom.

Look at this diagram of sulfur. What is the most likely thing that will happen to complete the outer shell?
options:
donate 2 electrons
donate 6 electrons
accept 6 electrons
accept 2 electrons
Answer:
Accept 2 electrons
Explanation:
Elements are most stable when their valence shells are filled. Since sulflur lies within the third row in the p-block, it wants 8 valence electrons. However, according to the diagram, it only has 6 valence electrons. The simplest way to having a filled outermost shell is the one which involves the least amount of electrons being added or donated to the element. In this case, the fastest way to a stable element is by adding 2 valence electrons (6 + 2 = 8).

Peppered moths live on lightly colored trees, lay around 100 eggs and don’t live longer than a year. How does that help them adapt and survive?
Answer:
They camouflage
Explanation:
The peppered moths adapt to their surroundings. They blend in with their surroundings to avoid being eaten by their predators. Blending in with their surrounding also helps them to sneak up on and catch their prey.
I'm not too sure why they lay 100 eggs at a time but i think it's because the parents want to increase the survival of their eggs. Eggs sometimes are eaten by other animals and the parents want at least a few to survive.
