Explanation:
when a vegetable gets put in salt water and collapses why does this happen
Osmosis is defined as the movement of solvent (like water) from a region where the concentration of solute(like salt) is lower to a region where the concentration of solute is higher through a semipermeable membrane.
Salt water is a hypertonic solution as the concentration of salt ( solute) is higher. Therefore, in this case water from vegetable will move outside causing the cells to become fragile.
Hemolysis of red blood cells occurs when the cells are placed in a(n) Group of answer choices hypotonic solution physiological saline solution hypertonic solution isotonic solution
Answer:
Hypotonic solution
Explanation:
Haemolysis of red blood cell refers to the destruction or breakdown of red blood cells. Red blood cell will undergo haemolysis if placed in an Hypotonic solution. Hypotonic solution is a solution that contain smaller amount or lower concentration of solutes like dissolved salt than other solution and also compared to the cystol. If a cell is placed in Hypertonic solution, red blood cell will swell because it will absorb solute and undergo hemolysis burst when placed in a hypotonic solution.
What type of transport is illustrated in the diagram and what type of molecule would be transported
using this process?
A. Passive transport; carbohydrates
B. Active transport; oxygen
C. Exocytosis; proteins
D. Facilitated diffusion; sugars
What is photosynthesis
Answer:
The process of a plant converting sunlight, carbon dioxide and water into food
Explanation:
Hey there!
Photosynthesis is the reaction that converts light energy to chemical energy in sugar and carbohydrates. Humans can't eat sunlight, so we eat plants. Plants convert the energy in the sunlight into chemical energy using chlorophyll. Chlorophyll is a molecule produced by plants, algae, and cyanobacteria, which aids in the conversion of light energy into chemical bonds. It is the green pigment found in the chloroplasts of higher plants. They are a part of our ecosystem, and they are lower on the food chain.

12. Which has NOT been linked to acid precipitation?
a. Toxic metal poisoning
b. Lower blood pH
c. Respiratory problems
d. Damaged monuments
Answer:
D
Explanation:
Lower blood pH has not been linked to acid precipitation. So, the correct option is (B).
What is Acid Precipitation?Acid rain is defined as rain or any other form of precipitation that is abnormally acidic, meaning that it contains high levels of hydrogen ions. Most water which include drinking water, has a neutral pH that exists between 6.5 and 8.5, but acid rain has a pH level lower than this and averages between 4–5.
Acid rain can be caused by natural causes, such as volcanic eruptions, while acid rain can also caused by human activities such as the burning of fossil fuels, manufacturing, oil refineries, electricity generation, and vehicles, all of which release sulfur and nitrogen oxides into the atmosphere.
Thus, lower blood pH has not been linked to acid precipitation. So, the correct option is (B).

Carbon dioxide is carried in blood plasma.
Human blood also contains red blood cells and white blood cells.
Explain how the structure of red blood cells and white blood cells is related to their function.
(6 marks)
Answer:
Plasma is the main component of blood and consists mostly of water, with proteins, ions, nutrients, and wastes mixed in. Red blood cells are responsible for carrying oxygen and carbon dioxide. Platelets are responsible for blood clotting. White blood cells are part of the immune system and function in immune response.
Blood is important for regulation of the body’s pH, temperature, osmotic pressure, the circulation of nutrients and removal of waste, the distribution of hormones from endocrine glands, and the elimination of excess heat; it also contains components for blood clotting. Blood is made of of several components, including red blood cells, white blood cells, platelets, and the plasma, which contains coagulation factors and serum.
The graph below shows changes in the populations of two species that interact only with each other over a period of time.
Which statement best describes these two species?
Species A is a producer and species B is its consumer.
Species A is a host and species B is its parasite.
Species A is a predator and species B is its prey.
Species A is a scavenger and species B is its decomposer.
The statement that best describes the two species depicted in the graph is option C) Species A is a predator and species B is its prey.
Option A indicates that species A is a producer and species B is its consumer. This means that species B requires the output from species A to survive. Knowing this, we would expect to show that species B increases in population as the population of A increases, due to increased food supply, the graph shows the opposite scenario. Thus, option A is false.
Option B states that perhaps Species A is a host and species B is its parasite. This provides the same conditions and dependencies as option a, so for the same reasons that a is false, we can conclude that option B is false as well.
The final incorrect option is D, Species A is a scavenger and species B is its decomposer. This would mean that as the population of species B dies off, it increases the food supply of Species A which feeds on the decomposing members of species B. We would expect in this case, that species A would flourish as B dies off, however, we see that as species B dies, species A follows shortly after. This tells us that option D is incorrect.
The correct option is C, Species A is a predator and species B is its prey. This would mean that species A consumes the members of species B to survive. Therefore we would expect to see
Species B thrive as the population of A remains lowFollowed by the steep decline of species B's population as more predators begin to appear. Once the population of species B reaches a critical point, species A will not have enough food supply to sustain its population, and both populations would decline.
This is exactly what the graph depicts, so option C is correct.

Answer:
When a long-term environmental change occurs, certain individuals in a population will be better adapted for the new environment than others. These individuals will be more likely to survive and pass on their traits to their offspring. Over many generations, these favorable adaptations build up in a population. This may lead to speciation, which is the development of a new species.When a long-term environmental change occurs, certain individuals in a population will be better adapted for the new environment than others.

Los cloroplastos son los orgánulos celulares que en los organismos eucariotas fotosintetizadores se van ocupando de la fotosíntesis. Están limitados por una envoltura formada por las dos membranas concéntricas y contienen muchas vesículas, los tilacoides, donde se encuentran organizados los pigmentos y demás moléculas que convierten la energía lumínica en energía química, como la clorofila.
El término cloroplastos sirve alternativamente para designar a cualquier plasto dedicado a la fotosíntesis, o específicamente a los plastos verdes propios de las algas verdes y las plantas. Aunque el reciente descubrimiento adiciona a más individuos en la lista, como lo es en el caso de Elysia chlorotica, que al digerir al alga Vaucheria litorea, adquiere los cloroplastos a sus tejidos, y gracias a esto, puede realizar la fotosíntesis.

explain why a plant that does not get enough nitrate has weak growth
Answer:
Nitrate deficiency
Explanation:
Plants absorb nitrates in water through their roots. Nitrates are present in high levels in plant fertilisers. Without nitrates, the amount of chlorophyll in leaves reduces. This reduces the plant's ability to photosynthesise and grow properly, which reduces the farmers' crop yield .
