3.) What cellular processes are necessary for cells to perform in order to maintain homeostasis?
Vacuole, respiration, chloroplast and photosynthesis
Photosynthesis, respiration, diffusion, osmosis
respiration, osmosis , diffusion
Chloroplast, respiration, osmosis, diffusion
Answer:
Photosynthesis, respiration, diffusion, osmosis
Explanation:
Homeostasis refers to the ability of an organism to maintain a stable internal state despite changes in external environment. In order to perform this process, some processes are required to be performed by the cell including:
- Photosynthesis, which is the process by which plants synthesize their food, helps the plant supply energy needed by the cell to perform it's function.
- Cellular respiration is the process of synthesizing energy (ATP) by the cell. Energy is needed by the cell for the numerous functions it carries out. Hence, cellular respiration is a homeostatic process.
- Diffusion is the process by which substance move from a region of high conc. to a region of low conc. until there is even distribution. Without diffusion, some materials cannot get into the cell, hence, it is a homeostatic process.
- Osmosis is the movement of water from a region with high water conc. to a region of low water conc. via a permeable membrane. The osmotic process is also a homeostatic one.

(a) photosynthesis

In 1998, paleo anthropologist Rick Potts, of the Smithsonian Institution, published an article in The Yearbook of Physical Anthropology, a peer-reviewed journal. The article was titled “Environmental Hypotheses of Hominin Evolution.” In his paper, Potts provided evidence to support his claim that great variations in environmental conditions over time were responsible for the adaptability of humans and the success of our species. Why might this not be the best article to reference?
a) Potts has no authority.
b) Potts was not objective.
c) The article may not reflect current knowledge.
d) The article was not reviewed bu Potts's peers.

Here are the answers to the three questions on the right side of the page, as for the left, those are your own opinions, remember?
plate tectonics: a theory explaining the structure of the earth's crust and many associated phenomena as resulting from the interaction of rigid lithospheric plates which move slowly over the underlying mantle.three different types of late boundaries:Divergent boundaries -- where new crust is generated as the plates pull away from each other. Convergent boundaries -- where crust is destroyed as one plate dives under another. Transform boundaries -- where crust is neither produced nor destroyed as the plates slide horizontally past each other.crustal features formed at plate boundaries: Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines are examples of features that can form along plate tectonic boundaries.hope this helps ^^

what does cell cycle mean
Explanation:
a cell cycle is a series of events that take place in a cell and it grows and it divides a cell speeds most of its time and what is called interface and during this time it grows replicates into chromosomes and prepers for cell division.
here's an example of cell cycle with few exceptions ( for example, red blood cells) all the cells of living things undergo a few cycles the cell cycle is generally divided into two phases interface and mitosis during interface the cell spends most of its time performing the functions that make it unique
and how long does it cycle take usually cells will take between 5 and 6 hours to complete s phase. G2 is shorter lasting only 3 to 4 hours and most cells it's some then interface generally takes between 18 and 20 hours misosis during which the cell makes preparations for the complete cell division only takes about 2 hours
i hope this helps :)

If you have 100 grams of a radioactive isotope (the parent) with a half-life of 10 years, how much of the non-radioactive element (the daughter) will be left after 10 years?
The mass of the non-radioactive element (the daughter) that will be left after 10 years will be 25 grams. The correct option is d.
What is a radioactive isotope?Radioactive isotopes and radionuclides are chemical species of the same elements. Half-life is the time in which half of the radioactive element is reduced. It is the time period of the reduction of the initial half of the radioactive element.
Given the total radioactive element is 100 grams
The age is 20 years
The half-life is 10 years
Hence, the number of half-lives, n=20/10= 2
The formula is
N= (1/2)n No
Where, N = concentration of nonradioactive element
No = Concentration of radioactive element
Put the values in the formula
N= (1 / 2) 2 × 100 = 25 grams
Therefore, the correct option is d, 25 grams.

What role does mutation play in the evolution of an organism?
Answer:
Mutation plays an important role in evolution. The ultimate source of all genetic variation is mutation. Mutation is important as the first step of evolution because it creates a new DNA sequence for a particular gene, creating a new allele.

Which is one characteristic of polar climates that highland regions do not have? O a treelin cold temperatures O very little precipitation two seasons with temperature differences
plz help. will give Brainliest
Few trees, cold temperatures, and very little precipitation are the characteristics of polar climates.
What is polar climate?A polar climate is a regain where the climate usually has a temperature below freezing and mostly covered with snow. This is because polar climates don't get direct sunlight as compared to other regions. Polar climates are usually dry.
So we can conclude that Few trees, cold temperatures, and very little precipitation are the characteristics of polar climates.

Thylakoids membranes have special proteins in bedded into the membrane which catalyze the production of ATP from what type of ions
Answer:
From Hydrogen ion.
H+
Explanation:
It's is from hydrogen ion because majoroty of the electrons transport processes take place in the thylakoids membranes in a bid to produced ATP, Hydrogen ion is allow to move through thylakoid space and then backflow through the proteins embedded in the thylakoids membrane called ATP synthase, which produce ATP from ADP in the mitochondrial matrix and chloroplast stroma.
The “Rule of 10” states that as little as ________ % of the energy at any trophic level is transferred to the next trophic level.
If I am a higher trophic level organism, this means that I need to eat MORE / LESS (circle one) food in order to fulfill my energy needs.
The majority of the energy is lost as ________________ through the completion of metabolic processes.
Answer:
1) "Rule of 10" states that as little as 10% of energy is transferred
2) Higher trophic level organisms need to eat MORE food, as energy is lost between trophic levels

If all the macromolecules are made mainly of the elemwnts CHO, how are they different?
Is this cell haploid or diploid? How can you tell?
Answer:
The cell shown in the image is haploid, which can be affirmed by the presence of an odd number of chromosomes.
Explanation:
Haploid cells are those that have a single set of chromosomes, that is, half of the chromosomal charge (n) of an organism. These cells correspond to gametes.
Diploid cells are those with complete chromosomal charge (2n) and correspond to somatic cells.
The cell shown in the image is a haploid cell, since it has only three chromosomes. Because diploid cells contain chromosomes in pairs, even if the haploid cell of that species is odd or pair, diploids will always have an pair number of chromosomes.
