Will the cell swell or shrink ?
The cell is In what type of solution ? (Hypertonic , hypotonic ,isotonic ) help pls
The percentage of water inside the cell is 2.5 %. Water will move into the cell and it will swell. So it's a hypotonic solution.
What is osmosis?
Osmosis is the spontaneous diffusion or flow of water or other liquids over a semipermeable membrane, or one that prevents the passage of solutes, or dissolved compounds. The crucial biological mechanism was initially in-depth investigated in 1877 by German plant physiologist Wilhelm Pfeffer. Inaccurate investigations of leaky membranes, such as animal bladders, and the movement of water and other chemicals through them were previously conducted by other researchers.
A solution will tend to become more diluted by absorbing solvent through a membrane separating it from the pure solvent if the membrane is permeable to the solvent but not to the solute. The osmotic pressure, also known as the pressure exerted on the solution, can be raised to a certain level to halt this process. Jacobus Henricus van 't, Hoff, a Dutch-born chemist, demonstrated in 1886 that Henry's rule is obeyed if the solute is sufficiently diluted that its absolute vapor pressure is above the solution.
Therefore, the percentage of water inside the cell is 2.5 %. Water will move into the cell and it will swell. So it's a hypotonic solution.

Water takes a longer time to change temperature than alcohol does because water requires a larger amount of heat to be absorbed to cause the change.
()True
Or
()False
Answer:
True
Explanation:
Water freezes faster than alcohol due to lower freezing point.
Water takes less time to freeze than alcohol but can absorb a large amount of heat with only a small change in its temperature. Alcohol has -114.7 degrees Celsius of freezing temperature whereas water has freezing point of 0 degrees Celsius.
The given statement is true. Water freezes faster than alcohol. Due to its lower freezing point than alcohol, water freezes more quickly.
Why water freezes faster than alcohol?Alcohol takes longer to freeze than water, but water can absorb a lot of heat with just a slight change in temperature. Water has a freezing point of zero degrees Celsius, but alcohol has a freezing point of -114.7 degrees Celsius.
Because water molecules must be forced to move more quickly within the water in order for the temperature to rise, water is more able to absorb heat than many other substances. As a result, water freezes more quickly than alcohol.
Therefore, The given statement is true. Water freezes faster than alcohol. Due to its lower freezing point than alcohol, water freezes more quickly.

describe the features of the endocrine system for control in the example given.
- endocrine gland
-negative feedback mechanism
-produce hormone -> travel via blood-> target specific cells organs
Please expand these bullet points
Answer:
The endocrine system is a major system in the body composed of glands that secrete hormones, which are substances produced by the body to stimulate an organ or group of cells. The endocrine system controls essential bodily functions, which include movement, sexual development, sensory perception, and even growth.
Explanation:
Hormones are chemicals that are produced by the glands in the endocrine system and coordinate distinct bodily functions by carrying important messages throughout the body. They send signals to receiver cells in organs, muscles, and tissues.
Role of Hormones
Hormones have very essential roles in the body, as they regulate metabolism, growth, and sex development. For example, testosterone and estrogen are sex hormones that are released in the body to initiate sex development during puberty. The rate at which these hormones are produced and released must also be highly controlled for optimal development and growth. Hormones also control levels of hunger or exhaustion. Overall, they are very important in telling the body what to do and how to do it.
Function of Hormones
As previously mentioned, hormones serve several important functions throughout the body. They are responsible for the function of organs, in addition to controlling how the body stores and uses energy. Hormones only target specific organs or cells: for example, thyroid-stimulating hormones are released by the pituitary gland, and only target the thyroid gland. Some hormones can affect several kinds of tissues at once; for instance, the thyroid hormone, produced by the thyroid gland, can affect several bodily functions, such as heart rate and metabolism.

In three to five sentences, describe the advantages and disadvantages of these maps in modeling mitosis. I will give brainliest to best answer
Introduction
In order for organisms to grow, cells have two options: they must either replicate themselves to create more cells, or the cells themselves must expand in volume. In humans, tissues such as the skin and blood contain cells that are actively dividing, whilst other tissues such as fat contain cells that expand (good if you need energy for winter, bad if you are trying to fit into some expensive jeans). Other cells, such as neurons, will never divide again once they are terminally differentiated; they are post-mitotic.
In the process of replicating themselves, cells have another choice: do they want to make an identical copy and be left with two cells? Or do they want to make four “half-copies”, in preparation for sexual reproduction, where their genetic content will be made whole again by the process of fertilisation? This choice is the choice between mitosis and meiosis.
Difference Between Mitosis and Meiosis
This article will explore the characteristics of both kinds of cell division, shining a light on how they are similar and in which aspects they are crucially distinct. We will also explore the research into these processes and how cell division might go awry to cause disease states such as cancer and Down’s Syndrome.
Mitosis vs. Meiosis: Overview and commonly asked questions
Mitosis
Meiosis
What is the purpose of this process?
In a unicellular organism, the purpose of mitosis is to proliferate asa species. In a multicellular organism, the purpose can be to grow during development, or to repair or regenerate
adamaged tissue, for example.
To create gametes with only one copy of the organism’s genetic information, in preparation for sexual reproduction. Various steps in meiosis create opportunity for genetic diversity in the daughter cells. This is the raw substrate for evolution.
What is the outcome of this process?
Two diploid cells with identical genetic information.
Four haploid cells with different genetic information.
Which organisms perform this process?
Mitosis is performed by unicellular and multicellular eukaryotes.Bacteria have their own version of mitosis called “binary fission”.This is distinct from meiosis as bacteria typically have one circular chromosome,which is not contained within a nucleus, like eukaryotic chromosomes.
Only organisms which perform sexual reproduction. Archaeaand bacteria do not do this, so it might be tempting to think that unicellularorganisms do not sexually reproduce. However, there are exceptions; buddingyeast will form haploid spores under nutritional deprivation.
How long does this process take?
Mitosis is usually shorter than meiosis. The process can take over 10 hours for mammalian cells in culture [2], budding yeast can take ~80 minutes to complete a cell cycle [3], whilst bacteria can divide every 20 minutes.
Meiosis has various timescales in different organisms, which can be affected by several factors including temperature and environment of the organism, and the amount of nuclear DNA. The process lasts 6 hours in yeast but can last more than 40 years in human females, due to a developmental hold at prophase I, until ovulation. Other examples are 1-2 days in male fruit flies and ~ 24 days in human males. [1]
What is an example of a disease caused by an error in this process?
Uncontrolled mitosis occurs in cancer, where either genes that stop cell division (tumour suppressors) are switched off, or genes that encourage cell division (oncogenes) are overactive.
Errors in meiosis can lead to the wrong number of chromosomes ending up in germ cells, this is called aneuploidy. This can trigger miscarriage, but is occasionally tolerated. One example is Down’s syndrome, caused by trisomy 21. Another example is Klinefelter syndrome, where XY males have an additional X chromosome.
Summary
Meiosis and mitosis both have a prophase, metaphase, anaphase, telophase and cytokinesis.
In meiosis, prophase, metaphase, anaphase and telophase occur twice. The first round of division is special, but the second round is more like mitosis.
In mitosis, prophase, metaphase, anaphase and telophase occur once.
Prophase
Chromosomes condense and the centrosomes begin to form an early spindle.
Meiotic prophase I is much longer that mitotic prophase.
During prophase I homologous chromosomes make contacts with each other called chiasmata and “crossing over” occurs. This is where chromosomes exchange sections of DNA. This is important for generating genetic diversity but is also crucial mechanically to hold homologous chromosomes together.
Mitotic prophase is much shorter that meiotic prophase I.
There is no crossing over in mitosis.
(Im a really fast typer)
Answer:
Cells have to do a few things, first they either have to replicate themselves, or they must expand. In our human bodies our cells do both. Replicating when we break skin, and expanding for the winter. Some cells never divide though. But cells also have to choose is they will make identical copies, or 4 half copies. Half copies have a sexual re-productions. And this is the choice of mitosis and meiosis.

The eyes of some birds contain cells that detect ultraviolet (UV) light.
UV light is reflected by some fruits and the urine of small mammals.
Explain how birds that detect UV light have evolved from birds that could not detect
UV light
[6 marks
Birds that detect UV light have favorable characteristics that enable them to survive and reproduce. These characteristics are passed on to their offspring.
According to Darwin's theory of evolution, organisms that are better adapted to their environment live long enough to survive and reproduce and pass on these favorable traits to their offspring.
Since birds depend on these fruits for food and these fruits reflect UV light. A bird that can not detect UV light will find it difficult to obtain food. Hence, birds that have developed the ability to detect UV light will live long enough and reproduce, passing on these favorable characteristics to their offspring. Hence, birds that can detect UV light appears from birds who do not originally detect UV light.
