Answer:
Diffusion describes the movement of particles from an area of higher to lower concentration. That is what the ink is doing when it spreads throughout the jelly. Osmosis only occurs across a semipermeable membrane.
Answer:
osmosis is movement of particles through a semipermeable membrane from the region of high concentration to region of low concentration while diffusion is the movement of particles from a region of higher concentration to a region of lower concentration.
Explanation:
here there is no semipermeable membrane hence the correct answer is diffusion.
What is the difference between abiotic and biotic?
Answer:
Abiotic factors refer to non-living physical and chemical elements in the ecosystem. ... Examples of abiotic factors are water, air, soil, sunlight, and minerals. Biotic factors are living or once-living organisms in the ecosystem. These are obtained from the biosphere and are capable of reproduction.
Explanation:
When you exhale, what happens in the lungs?
A. Air moves from high pressure (in the lungs) to low pressure (outside)
B. Space in the lungs increases
C. Lung pressure decreases
D. Air moves from low pressure (in the lungs) to high pressure (outside)
Answer:
Conversely, exhalation moves the diaphragm up into the chest cavity and reduces the space in it. This forces the air, which is dense with carbon dioxide at that point, out of the lungs and windpipe. It then exits the body either through the nose or mouth. Usually, this requires no physical effort from the body.

Critical thinking : Do magnets need to touch a piece of iron or another magnet to exert a magnetic force on the iron or other magnet?
Answer:
I wouldn't think so because it is the magnetic field that Attracts and repels. When iron is magnetised to something don't the molecules lineup in the North the South pattern or something like that to create a magnetic field and stick together.
I might be wrong because this is my personal opinion on the matter.
Answer:
no because the magnetic force attracts the magnet or the iron to it

When an antigen attacks the body, it activates adaptive immunity. This adaptive immunity produces a strong response when it encounters the same antigen for the second time. Which feature of adaptive immunity is essential for this kind of response?
Answer:
A) the ability to remember the antigen it encounters
Adaptative immunity reacts in a more general way producing nonspecific antibodies against the foreign antigen when the organism is first attacked by that foreign antigen. The second time around, when the organism is faced again with the same foreign antigen, it produces a much stronger response because it memorised the antigen and is not strange anymore so the response can be more specific, quicker, and effective.

Answer: # 1: c. #2: d. #3: a
Explanation:
#1 is C. because the equation for cellular respiration is C₆H₁₂O₆
+ 6O2 --> 6H20 + 6CO2 + ATP
This says the reactants (inputs) are oxygen and glucose and the products (outputs) are water, carbon dioxide, and ATP. 1 glucose molecule makes 6 carbon dioxide, so 3 glucose would make 18 carbon dioxide molecules.
#2 is D. because the law of conservation of matter states that matter cannot be created nor destroyed, so the weight before and after cellular respiration would stay the same, as the matter would not change.
#3 is A. because a model would show the exact way the molecules would be arranged, while a formula only tells you how many there are, not the way they would be made up.

Answer: Graph A
Explanation:
Since photosynthesis primarily takes place in the leaves, it is essential that glucose can be transported out of the
cell to other parts of the plant. The selectively permeable plasma membrane only allows certain molecules to
cross freely through the phospholipid bilayer.
Is glucose a molecule that is allowed to cross the selectively permeable membrane freely?
Answer: A
No, glucose passes through a channel protein with the concentration gradient via facilitated diffusion.

Inherited genetic variations are caused and influenced by environmental factors only. Factors like an organism’s habitat conditions and behavior can affect variation within a population. PLEASE EXPLAIN HOW ENVIRONMENTAL FACTORS EFFECT GENETIC VARIATION! WILL MARK BRAINLIEST!!
Answer:
Genetic variation among plant populations often occurs along different climatic gradients, such as temperature and precipitation gradients. Environmental factors are often responsible for the patterns of genetic structure observed at small spatial scales
Explanation:
Over various spans of time, human populations have increased, decreased, or remained the same, and at both global and local levels. Which statement best explains this observation?
Answer:
C. Like other populations, the human population is affected by a variety of factors in the environment
Note: The options are found in the attachment below
Explanation:
Factors that affect population in the natural world include; availability of food, water, shelter, space, competition for resources, predation, as well as disease.
These factors also affect human population resulting in an increase, decrease or stability in population.
Regarding decrease in population, factors like competition for scarce resources has resulted in wars which greatly reduced human population. Also disease outbreaks, droughts, famines, etc have resulted in decrease in population.
Availability of food, water, shelter and space on the other hand makes for an increase in population by increasing the birth rate, reducing competition and bringing stability.
In some other instances, overtime, there is a balance between birth and death rate, so human population will remain relatively unchanged at these times.
b) Identify a dependent variable in the experiments. Identify the reasoning of the scientists when they tested the number of colonies produced by strains C3-PBB and C6-PBB . The scientists also analyzed the number of colonies produced from each of the environmental and clinical isolate strains when the strains were plated on a growth medium lacking the toxic chemical. Justify this analysis.
A dependent variable is the number of colonies produced. The experiment gives a useful insight into the toxicity of the chemicals.
A scientific experiment must always have a dependent and an independent variable. A dependent variable is the variable whose outcome is being determined by manipulating the independent variable which in this case is the presence or absence of the chemicals.
Toxicity of chemical substances is a very important information to scientists as such this experiment is very important because it highlights the toxicity of the chemicals to living things.

The IQ range that indicates moderate mental *********** is A. 70-79.
What is an IQ?
IQ stands for Intelligence Quotient and is a measure of cognitive abilities and intellectual potential. It is determined through standardized tests that assess various cognitive skills, including problem-solving, memory, and analytical thinking.
The average IQ score is set at 100, with scores ranging from 70 to 130 considered to be within the normal range. Scores below 70 indicate varying degrees of intellectual disability, while scores above 130 suggest above-average intelligence.
While IQ scores can provide insight into a person's cognitive abilities, they do not account for other factors, such as emotional intelligence or creativity, that may contribute to overall success in life. It is essential to recognize that IQ tests have limitations and should not be used to label individuals or limit their potential.
This range is considered to be a mild to moderate intellectual disability, indicating limitations in adaptive functioning and potential need for support in daily life activities.

What kind of atoms are in an amino acid?
Answer:
The term amino acid is short for α-amino [alpha-amino] carboxylic acid. Each molecule contains a central carbon (C) atom, called the α-carbon, to which both an amino and a carboxyl group are attached. The remaining two bonds of the α-carbon atom are generally satisfied by a hydrogen (H) atom and the R group.
