plants cells would not not have been able to absorb these minerals ions from the pond by diffusion . explain why not
Answer:t hey cannot be absorbed by diffusion , because the minerals are in very low concentration. Instead, active transport is used. ... Because active transport moves ions against the concentration gradient into the root hair cells, energy is needed.

PLS HELP ASAP Select the word that means how easily water can move through a substance. Lesson 2.03 o particles permeability porosity
Answer:
permeability
Explanation:
dictionary definition: the state/quality of a material or membrane that causes it to allow liquids or gases to pass through it
in biology we use this term to describe the cell membrane, it is "semi-permeable" because it allows certain gasses and molecules to pass through
The water can easily move through a substance and it is called permeability. Hence, option B is correct.
What is permeability?The ability of molecules to pass through a biological membrane or barrier is known as biological permeability. Because cell membranes are selectively impermeable, substances cannot pass through the barrier without consideration. Some of the characteristics that affect permeability include polarity, hydrophobicity, charge, size, and shape.
The metabolic activities, survival, and potential use of the cell in both biotechnological applications and physiological systems are all greatly impacted by the cell membrane permeability, which controls the rate of solute transport into and out of the cell.
The water can easily move through a substance when the substance is permeable. Hence, option B is correct.

How many molecules of carbon dioxide is produced from cellular respiration?
Answer:
six
Explanation:
Since two acetyl-CoA molecules enter the cycle, and each has two carbon atoms, four carbon dioxide molecules will form. Add these four molecules to the two carbon dioxide molecules formed in the conversion of pyruvic acid to acetyl-CoA, and the total is six carbon dioxide molecules.

What are the 3 main processes common between terrestrial and aquatic ecosystems?
Answer:
Three main processes that are common between these are that they both make food through photosynthesis, they both perform transpiration, and they both need sunlight in order to process chemical energy.
I really hope this helped and have a great day! :)
The process that are seen in both terrestrial and aquatic ecosystems are;
Transpiration process
Photosynthesis for food synthesis
Energy through sunlight.
An ecosystem can be regarded as geographic area which contains plant as well as animals with other organisms and weather and landscape and they all carried out different functions so that bubble of life is formed.Ecosystem could be terrestrial as well as aquatic ecosystems.An aquatic ecosystem can be regarded as types of ecosystem containing body of water. In contrast to terrestrial ecosystems that is associated to land, there are Communities of organisms that their dependent is on each other as well as the environment all live in aquatic ecosystems.Aquatic ecosystems could contains body of oceans as well as lakes rivers, and stream.Terrestrial ecosystem can be regarded as community of organisms that dominate land, as well as interactions that exist between biotic as well as abiotic components in a given area. Some of terrestrial ecosystems are tundra, taigas as well as temperate deciduous forests and tropical rainforests.Some of the processes that can be attributed to both terrestrial and aquatic ecosystems are;
Making of their food could be through photosynthesis, this is the process whereby plant makes their food through the energy from sunlight.Sunlight is required as a source to process energy. Transpiration can be regarded as process involving movement of water through a plant, this could also encompass the evaporation of this water from aerial parts which could be in the leaves as well as stems and flowers.Therefore, both terrestrial and aquatic ecosystems have some process in common.

Answer:
Golgi body
Explanation:
A cell organelle is a structure found in a cell that plays a specific role or function. Some of the cell organelles in living cells include nucleus, mitochondria, chloroplast etc. Ideally, the NUCLEUS, which is the organelle that directs the processes of other organelles contain the genetic material called DNA, which is a type of nucleic acid.
However, some organelles like mitochondria, ribosome and chloroplast also contains nucleic acid.
- Mitochondria contains it's own DNA nucleic acid.
- Chloroplast, also contains its own DNA nucleic acid.
- Ribosomes contain RNA (ribosomal RNA and transfer RNA).

The diagram shows the motion of a group of water molecules over a heat source.
How do the molecules at point A compare to the molecules at point B?
They are farther apart.
They have increased in size.
They have lost energy.
They are moving slower.
Answer:
I am currently doing this and the answer should be A.
Explanation:
Warmer liquid rise so that means that A is hotter and B is colder this is way B is moving down. This means that C and D can not be correct, and the molecules do not grow.
They are farther apart shows the motion of a group of water molecules in diagram over a heat source. Thus the correct option is A.
What is motion?Motion is defined as the change with time of the position or orientation of a body. Motion which changes the orientation of a body is called rotation.
Warmer liquid rise so which means that A is hotter and B is colder this is way B is moving down. This means that C and D can not be correct, and the molecules do not grow.

The Sierra Nevadas are an example of a fault-block mountain range. Based on this information, which of the following processes formed the Sierra Nevadas?
Melted rock called magma rose through holes in Earth's crust and gradually solidified as it cooled.
Tectonic movement forced certain segments of Earth's crust downward and other segments upward in jagged chunks.
One tectonic plate moved beneath another plate at a subduction zone, causing the rock to melt and rise above Earth's surface.
Segments of Earth's crust bent and doubled over, and moving wind and water gradually shaped the rock into gently sloping domes.
Answer:
2nd answer
Explanation:
took the test
As per the given scenario, tectonic movement forced certain segments of Earth's crust downward and other segments upward in jagged chunks. The correct option is B.
What is tectonic movement?The mobility of the plates that end up making up the Earth's crust is referred to as tectonic shift. The Earth is composed of a dozen major plates and several minor plates.
According to the situation, tectonic movement pushed certain segments of the Earth's crust straight down and others upward in jagged chunks.
Thus, B is the correct answer.

What role does reproduction play in both natural and artificial
selection?
Answer:
It allow organisms to pass down their traits to the next generation.
Explanation:
Reproduction can be defined as a biological process which typically involves living organisms producing an offspring.
Basically, there are two (2) methods of reproduction and these are;
I. Sexual reproduction: it involves the combination of the genome (gamete) of a male and female living organism during fertilization.
II. Asexual reproduction: it involves the cloning of a living organism to produce an offspring because there is only a single parent.
Natural selection can be defined as a biological process in which species of living organisms having certain traits that enable them to adapt to environmental factors such as predators, competition for food, climate change, sex mates, etc., tend to survive and reproduce, as well as passing on their genes to subsequent generations.
Simply stated, natural selection entails the survival of the fittest.
Artificial selection is also known as selective breeding and it is a process that involves humans (breeders) selecting the animal or plant with desirable traits in order to reproduce favorable offspring having phenotypic traits.
Hence, the role which reproduction play in both natural and artificial selection is that it allow organisms to pass down their traits to the next generation.

Explanation:
the trait is recessive (given) which means in order to have it, you must obtain both alleles. in the pedigree, shaded shapes indicate people who have the trait, but person 1 in row 3 is not shaded so their genotype must be AA (dominant) or Aa (dominant leading) and their phenotype would not express the trait, because the dominant allele will "take over"
