What is the function of the cell membrane? The cell membrane controls what goes into the cell (food) and what leaves the cell (waste). The cell membrane protects the cell from damage. The cell membrane controls the amount of water that goes into the cell and stores it there if it doesn't rain. The cell membrane allows air to enter, but won't allow water to enter into the cell.
Answers
Answer:
Cell membranes serve as barriers and gatekeepers. They are semi-permeable, which means that some molecules can diffuse across the lipid bilayer but others cannot. Small hydrophobic molecules and gases like oxygen and carbon dioxide cross membranes rapidly

A DNA molecule with a total of 1500 nucleotides has 300 cytosines. How many thymines does the DNA molecule have?
Answers
The DNA molecules will have 450 thymines if a DNA molecule has a total of 1500nucleotides
A DNA molecule also known as deoxyribonucleic acid is made up of a double helix.
The DNA molecule with a total of 1500 nucleotides will contain 750 cytosine and Thymines and 750 guanines and adenine.
Hence we can have the expression:
C + T = 750
If there are 300 cytosines, hence;
300 + T = 750
T = 750 - 300
T = 450
This shows that the DNA molecules will have 450 thymines

What is the important of ecological factors to organisms
Answers
Explanation:
The ecological factors that affect the growth of plants and determine the nature of plant communities are divided into three types.
The three types of ecological factors are: (1) Climatic factors which include rainfall, atmospheric humidity, wind, atmospheric gases, temperature and light (2) Physiographic factors which include altitude, effect of steepness and sunlight on vegetation and direction of slopes (3) Biotic factors which include interrelationship between different plants of a particular area, interrelationship between plants and animals occupying the same area and interrelationship between soil microorganisms and plants.
I. Climatic Factors:
The important climatic factors of a region are rainfall, atmospheric humidity, wind, temperature, and light. Of these climatic factors each one individually contributes to the general and overall effect of climate by influencing the life processes of plants which constitute the vegetation.
what you know about meiosis, fertilization, genotypes, and phenotypes to describe how traits are inherited. Include predicted ratios of types of offspring. This is a combination of learning objectives 3.18 (meiosis), 3.23 (fertilization), 4.1 on inheritance, and 4.2 on monohybrid crosses. This will require deep thinking about how these four learning objectives are connected.
Answers
Meiosis is a type of cell division in which four daughter cells are produced from a single parent cell. In each daughter cell, half number of chromosomes are present. This type of cell division occurs in sex cells such as sperm and eggs.
Fertilization is a process in which a sperm cell successfully meets or combine an egg cell. The newly fertilized cell is called zygote is produced during the process of fertilization.
A genotype is a collection of genes. Genotype is also refer to the two alleles that are inherited for a particular gene. The genotype is expressed when the information encoded in the genes' DNA is used to make protein and RNA molecules.
The term "phenotype" refers to the physical properties of an organism which can be seen. Phenotype includes the appearance, development, and behavior of an organism. An organism's phenotype is determined by its genotype.
Meiosis, fertilization, genotypes, and phenotypes are interconnected to each other because all these terms perform a specific contribution in the process of reproduction.

3. The doctor tests the patient's field of view with an astigmatism chart and finds that the patient states that there are blind spots and distorted lines in both eyes he never noticed before. These blinds spots and distortions remain constant. What structure within the eye could cause these distortions? How can you verify your suspicion?
Answers
Astigmatism is also a eye condition which is usually evidenced by distorted visions and leading to the creation of an image that is not perfect.
The structure within the eye that would cause the distortions is caused by a deviation in the shape of the lens of the eye or the cornea.
A change that occurs in the shape of the cornea/lens where it is not completely round as it should be usually leads to seeing distorted lines in one's vision and it can occur maybe from birth, even from injury to the eyes.
One can always verify this suspicion by going to seen an optometrist and doing a comprehensive eye examination to verify the condition. The condition is also treatable.

What’s the term to describe a mutant viral protein without a genetic code that can cause disease?
Answers
Answer:
'Prion' is a term first used to describe the mysterious infectious agent responsible for several neurodegenerative diseases found in mammals, including Creutzfeldt-Jakob disease (CJD) in humans.
Explanation:
The term to describe a mutant viral protein without a genetic code that can cause disease is a "prion." Prions are abnormal forms of proteins that can induce misfolding of normal proteins, so option a is correct option.
The misfolded prion protein can convert normal proteins of the same type into the abnormal misfolded form of protein, leading to a chain reaction and accumulation of misfolded proteins. This can cause damage to brain tissue and result in the characteristic symptoms associated with prion diseases, which include changes in behavior, neurological dysfunction, and ultimately, severe neurological degeneration. so option a is correct option.

a human organ is being prepared for transplant. in what type of solution must it be bathed?
A. A hypertonic solution
B. A hypotonic solution
C. Pure water containing solutes
D. A solution with the same osmolarity as the organ tissue
Answers
it must be bathed in a solution with the same osmolarity as the organ tissue.. inorder for it not to gain or lose its solute concentration.
I it is placed in a hypotonic solution it will gain water and eventually burst and if placed in a hypertonic solution it will lose water and shrink.
it must be bathed in solution with the same osmolarity as the organ tissue.
Osmosis allows for the diffusion of water from the region of higher concentration to the region of lower concentration.
Osmolarity measures the amount of solute concentration
For an organ place in a hypertonic solution i.e solution that has a higher solute
organ bathed in a hypertonic solution will continue to absorb in more water which can eventually burst the organ when it is too muchFor organ in hypotonic solution i.e solution that has a lower solute concentration
organ bathed will have to lose more solution because itself has more solute than the solution and can lead to shrinkagebut when the osmolarity is the same the Organ will have the same solute concentration as the solution and will help keep the organ in its original form, it will not absorb or lose any 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
Answers
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.
