Organs working together will form an organ system. Therefore ,option (C) a system is correct.
What is an organ system?An organ is a collection of tissues that work together to do its job, and an organ system is a group of organs that work together to do a certain job. There are eleven organ systems in a human body.
The respiratory system, the digestive and excretory system, the circulatory system, the urinary system, the integumentary system, the skeletal system, the muscular system, the endocrine system, the lymphatic system, the nervous system, and the reproductive systems are all considered to be part of the 11 organ systems.

which reason best explains why the cell membrane helps the cell maintain homeostasis
The correct answer is:
A. The cell membrane is selectively permeable.
Explanation:
A selectively permeable cell membrane is a cell membrane that concedes certain molecules, and/or ions to pass inside it by means of active or inactive transport. Cell membrane assumes a vital part in saving up the homeostasis by regulating the substances that infiltrate the phone, either opening the phone or leaving the phone.

What process uses atomic particles of carbon and uranium to determine exact age?
Answer:
Radioactive dating
Explanation:
Radioactive dating is also know as radioisotope dating. It is a technique used to find out the age or used to date materials such as rocks or carbon by determining the relative amounts of some radioactive elements present in the specimen. By "age" it is meant by time elapsed from when the mineral specimen was formed.

Using at least three sentences, explain the cycling of energy through the processes of photosynthesis and cellular respiration .
Answer and explanation;
Photosynthesis and cellular respiration are connected through an important relationship. The products of one process are the reactants of the other.
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water. While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide.
Cellular respiration and photosynthesis are important parts of the carbon cycle. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.

Why aren't we overrun with rabbits? what do you think keep the wild rabbits population in check?
Rabbit populations are controlled by natural predators, diseases like the myxoma virus, habitat loss, and human intervention. Predator-prey dynamics and habitat conservation are key aspects of maintaining the balance of rabbit numbers in the wild.
The wild rabbit population is kept in check by several factors, including natural predators, disease, habitat destruction, and human intervention. Predators such as hawks, stoats, ferrets, weasels, and lynxes play crucial roles in controlling rabbit populations by hunting them for food. For example, the population cycles of the snowshoe rabbit and its predator, the lynx, show how predator-prey interactions can impact rabbit numbers. Disease can also regulate rabbit populations; the myxoma virus outbreak in Australia in the 1950s significantly reduced rabbit numbers, though the population did recover to some extent. Additionally, loss of habitat due to human activities like urbanization, intensive agriculture, and the removal of hedgerows and fencerows, which are crucial for providing shelter and food for rabbits, has led to a decline in their numbers. Conservation efforts and public education about maintaining natural habitats can support the preservation of wildlife, including rabbits and their predators.
which element is most likely to share electrons with other atoms in joint orbitals
a) chlorine (7 valence electrons)
b) calcuim (2 valence electrons)
c) argon (8 valence electrons)
d) carbon (4 valence electrons)
e) potassium (1 valence electron)
Answer:
Carbon.
Explanation:
Covalent bonds is the chemical bonds that are formed by the mutual sharing of the electrons. The covalent bond is the strongest bond in the nature.
Carbon has the ability to form to form covalent bond. Carbon neither gains electron ( 6 protons cannot hold 10 electrons) and nor looses electron ( due to high ionization energy). So carbon forms bonds by the sharing of the electrons with the other atoms even in joint orbital.
Thus, the correct answer is option (d).

Answer:
please give me brainlist and follow
Explanation:
Transport proteins can form a larger opening or pore that allows molecules to pass. Under what conditions would a molecule need to be actively transported across a membrane? A molecule would need to be actively transported when the concentration of the molecule is higher on the other side of the membrane.

The table below shows the age of fossils found in four separate layers of an undisturbed rock:
Fossils In Rock Layers
Layer Fossil in Layer Age of Fossil (million years)
A W 550
B X 240
C Y 680
D Z 450
Which is the topmost layer of the rock?
Layer A
Layer B
Layer C
Layer D
The topmost layer of the rock is : Layer B
From the table the layer B is 240 million years and it is the youngest layer. While the oldest layer in the table is Layer C which is 680 million years old.
During the arrangement of rock layers of an undisturbed rock ( i.e. rock that has not undergo any form of metamorphosis either artificially or naturally ) the oldest layer of the rock is found at the base of the rock while the youngest layer is situated as the topmost layer of the rock.
Hence we can conclude that the topmost layer of the rock is Layer B

Why and/or how are invasive species of plants introduced to new foreign areas?
 This substance makes up the majority of your cells, and is necessary for them to carry out most of their chemical reactions.
What is it?
A)Carbon B)Oxygen C)Sugar D)Water
Answer:
(D). water.
Explanation:
Water makes up majority of all cells and is the most abundant molecule present in a cell along with other major biomolecules. It accounts for about 70% of total cell mass.
Water is necessary for the cells to perform most of their chemical reactions as it acts as a solvent and helps in transport of dissolved compounds from or into the cells.
Thus, the correct answer is option (D).
Describe the relationship between ATP and ADP and the importance of this relationship within a cell. (10 points)
ATP and ADP have a significant energy-providing relationship in cells. When a cell needs energy, ATP is broken down into ADP, releasing energy for the cell's usage. The cell then regenerates ATP from ADP during cellular respiration.
Explanation:The relationship between ATP (Adenosine Triphosphate) and ADP (Adenosine Diphosphate) is essential to the energy dynamics within a cell. ATP is known as the 'energy currency' of the cell because it provides energy for biological processes. When a cell needs energy, it breaks down ATP into ADP and an inorganic phosphate, releasing the energy stored in the bond for the cell to use. The significance of this relationship lies in its ability to maintain the energy balance in a cell.
Once ATP has been converted to ADP, it is crucial that the cell restores ATP for future energy needs. The cell does this in a process known as cellular respiration in which glucose and other nutrients are broken down to regenerate ATP from ADP, hence keeping the cycle of energy extraction and recovery going.
