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.
What problem would unlimited cell growth pose for a cell
Describe a cell which effectively uses diffusion as a means to move materials in and out. Suggest how being small helps cells survive, and being made of many small cells helps large organisms maintain homeostasis.
I don't know of any cells which effectively uses diffusion as a means to move materials in and out.
Single-celled organisms like amoebas efficiently utilize diffusion for the exchange of nutrients and waste due to their small size, which supports an adequate surface area to volume ratio. For multicellular organisms, consisting of many small cells aids in maintaining homeostasis by ensuring efficient substance exchange.
Cells that effectively use diffusion to move materials in and out include single-celled organisms like the amoeba. Due to the limiting effects of diffusion on size and development, these cells must remain small. Diffusion is an efficient process for the exchange of nutrients and waste in these cells, primarily because their small size allows for adequate distribution throughout the entire cell. As cells grow larger, the center of the cell might not receive enough nutrients or dispose of waste effectively due to the increased distance substances must travel.
Being small helps cells survive as it increases the surface area to volume ratio, which is favorable for diffusion to occur efficiently. For larger, multicellular organisms, being made of many small cells rather than fewer large cells aids in maintaining homeostasis because it ensures that all cells are close enough to the organism's external environment or to internal transport systems like blood vessels, which helps in efficient diffusion and transport of substances.
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).
 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).

Under what conditions would a molecule need to be actively transported across a membrane?
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.

Which is a shared characteristic of all animals? A) they are autotrophs B) they are vertebrates C) they are invertebrates D) they are heterotrophs
The answer is D they are heterotrophs
Answer:
D) they are heterotrophs
Explanation:
All animals are heterotrophs. This means that they get the nutrients (nitrogen, carbon, etc.) and the energy they need to live through plants or other animals, since they do not have a system for the production of their food. All animals need carbon for the proper functioning of their basic processes, such as growth, development and reproduction.

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.

Which of the following is not a correct equation for centripetal force?
A. Fc=mac
B. F=m v2/t
C. F=m v/r
Explanation:
When a body is moving in a circular path then a force acts on it and this force is directed towards the center around the moving object.
Mathematically, F = [tex]m\frac{v^{2}}{r}[/tex]
where F = force
m = mass
v = velocity
r = radius
The term [tex]\frac{v^{2}}{r}[/tex] is the centripetal acceleration.
Also, expression for centripetal force can be [tex]F_{c} = ma_{c}[/tex], where [tex]a_{c}[/tex] represents acceleration of centripetal force.
Whereas both the expressions F = [tex]m\frac{v^{2}}{t}[/tex] and F = [tex]m\frac{v}{r}[/tex] are not a correct equation for centripetal force.

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.

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
