Answer:
D. muscles
Explanation:
They are adapted to contraction due the elastic cella
internal structures of animals are specifically adapted to use contraction to cause movement muscle. They are adapted to contraction due the elastic cell
what are the types of muscle ?Three major types of muscles are skeletal muscle, smooth muscle and cardiac muscle.
Skeletal muscle, attached to bones, responsible for skeletal movements. where the peripheral portion of the central nervous system (CNS) controls the skeletal muscles.
The unit is the muscle fiber with many nuclei, these are either striated and each acts independently of neighboring muscle fibers.
Smooth muscle located in the walls of the hollow internal organs like blood vessels, the gastrointestinal tract, bladder, and uterus which is under control of the autonomic nervous system.
Cardiac muscle present in the heart wall under control of the autonomic nervous system, it has one central nucleus, like smooth muscle, is striated, like skeletal muscle, rectangular in shape. The contraction of cardiac muscle is involuntary, strong, and rhythmical.

Write a short answer below describing each energy transformation in the diagram which is located
above. For example describe how photosynthesis captures energy in and releases energy out (include
what form of energy). Next describe how cellular respiration captures in and releases energy out (inlcude
in what form.)
Answer:
Photosynthesis: the plant takes in energy from the sun, converts it into glucose (photosynthesis), and releases energy as Oxygen Gas (O2)
Cellular Respiration: Food is taken in by the organism and process in the digestive system going through aerobic processes and is released by Carbon Dioxide (CO2).
Explanation:
You need Carbon Dioxide to start Photosynthesis including water and sunlight, the process inside the plant undergoes the Calvin Cycle, Carbon Fixation, and Reduction. Plants can also go into fermentation engulfing alcohol or lactic acid (when your muscles are sore after you work out). Oxygen gas is released after carbon fixation turning into pyruvate and is no longer needed to continue the process.
You need Oxygen Gas to start Cellular Respiration. Inside the cells, Glycolysis, Pyruvate Oxidation, the Krebs Cycle, and Oxidative Phosphorylation occur. After the reaction, Carbon Dioxide (CO2) is released from the cells as heat.

What does it mean to impregnate xylem a cell wall?
Answer:
The walls of xylem cells are lignified (strengthened with a substance called lignin). This allows the xylem to withstand pressure changes as water moves through the plant.
Explanation:
The xylem transports water and minerals from the roots up the plant stem and into the leaves.
In a mature flowering plant or tree, most of the cells that make up the xylem are specialised cells called vessels.
Vessels:
Lose their end walls so the xylem forms a continuous, hollow tube. Become strengthened by a chemical called lignin. The cells are no longer alive. Lignin gives strength and support to the plant. We call lignified cells wood. Transport in the xylem is a physical process. It does not require energy.

A scientist studying the Milky Way galaxy notices a bright light in the sky. What information would she need to prove that the object is a comet and not a star?
Answer:
She would need lots of info, but some examples are,
A. Whether or not the subject is moving
B. Whether or not the subject disappears after a set amount of time
C. Whether or not the subject is near or far, and if it changes in size.
Explanation:
The correct answer is I and II.
A comet is made up of ice, dust, and small rocks or particles. They revolve around the sun and can be considered a member of the solar system. When they pass close to the sun they get heated due to solar radiation and start to release gases that are initially in the condensed phase. This release of gases produces a glowing tail behind the comet. When warmed up they produce a bright coma which can be of the order of several times the diameter of Earth.

\What did you have to do to turn an atom that is labeled “+ion or -ion” into a “Neutral Atom”?
Answer:if an atom is labeled as +ion then it needs electron to be neutral ,
but
if an atom is labeled as -ion then it has to lose electrons to be neutral.
Explanation:
A positive and negative ion can be converted to neutral by adding or deleting electrons respectively.
What is an Atom?It is the smallest particle that can represent an element. It is consist of electron, proton, and neutron.The electrons are negative particles and revolve around the nucleus. Protons are positive particles found inside the nucleus with neutrons. The number of positive and negative particles is equal inside a nucleus.A positive ion may lose one or more electrons and a negative ion may have one or more extra electrons.Therefore, a positive and negative ion can be converted to neutral by adding or deleting electrons respectively.

Explain in detail how the longer, more colorful tails evolved in peacocks despite causing disadvantages for the males.
Answer:
Due to mating
Explanation:
The longer and more colorful tails evolved in peacocks in the process of natural selection in order to preserve the peacock species despite causing disadvantages for the males.

Farming the land has a decreasing effect on the overall amount of soil
erosion.
True or false ?
Answer:
False
Explanation:
Farming practices disturb the ground. Farmers remove native vegetation and then plow the land to plant new seeds. Tractor tires make deep grooves, which are natural pathways for water. Fine soil is blown away by wind.
Answer:
False.
Explanation:
Agriculture is perhaps the foremost vital activity that accelerates erosion due to the quantity of land that's farmed and the way abundant farming practices disturb the ground.
describe how bears have evolved in order to be successful animal species?
Answer:
Evolution of Polar Bears
Explanation:The fossil transitions leading to our knowledge of development of the Polar Bear species are very well documented. Bear fossils change through time; i.e., as higher levels of sediments and sedimentary rocks are examined, more recent fossils are found.
The observed fossil transitions that inform our knowledge of Polar Bear speciation are very well documented. Bear fossils change through time: generally, when examining the fossil record, successively deeper levels of sediments or sedimentary rocks yield successively older fossils. For some transitions from one species to another, one can find a well-characterized series of transitional specimens leading the observer across the species "boundaries" (Kurten, 1976).

If an animal fossil was found in a rock, what would be the best way to determine its absolute age?
*analyze the rock’s mineral composition
*take X-rays of the fossil and surrounding rock
*compare it to similar-looking fossils that have already been dated
*measure the ratio of a radioactive isotope and its decay product present in the rocks around the fossil
Answer:
D
Explanation:
Absolute age is defined as the numeric age of fossils.
To identify the absolute age of a fossil, the amount of certain radioactive elements in the rock are measured. When fossils are formed in the rocks, a small amounts of radioactive elements is included in it. The process to identify age of fossil using radioactive elements is known radiometric dating. So, radioactive isotope and its decay product gives absolute age of fossils.
Hence, the correct answer is "D".
