When shellfish ingest dinoflagellates, a) they turn red. So,correct option is a.
Red tides are conditions when a dinoflagellate ingest builds to such gigantic numbers that it stains the water. This "sprout" might be brought about by supplement and hydrographic circumstances, albeit the natural circumstances which bring about red tides are not totally perceived. For dinoflagellate red tides, the water is stained red or brown due to as high as 20 million cells for every liter. These red tides are made fundamentally out of one types of dinoflagellate that has been quickly developing and gathering.
The dinoflagellates are a monophyletic gathering of single-celled eukaryotes comprising the phylum Dinoflagellata and are generally viewed as green growth. Dinoflagellates are generally marine tiny fish, yet they likewise are normal in freshwater natural surroundings. Their populaces differ with ocean surface temperature, saltiness, and profundity. Many dinoflagellates are photosynthetic, yet a huge part of these are truth be told mixotrophic, consolidating photosynthesis with ingestion of prey (phagotrophy and myzocytosis).

Hey Siri what is a prokaryotic cell?
Answer:
Prokaryotes are organisms whose cells lack a nucleus and other organelles. Prokaryotes are divided into two distinct groups: the bacteria and the archaea, which scientists believe have unique evolutionary lineages. Most prokaryotes are small, single-celled organisms that have a relatively simple structure.
What happens to a cell if it accumulates too much damage?
Each subsequent cell division produces daughter cells with more accumulated damage. Eventually, all checkpoints fail and rapidly regenerating cells crowd out normal cells, leading to tumor growth.
When a cell accumulates too many changes (when its DNA is damaged and the repair machinery cannot repair it), it either stops dividing or self-destructs. It may become cancerous.
If the damage is irreparable, cells may undergo apoptosis or programmed cell death. This self-destruct mechanism ensures that damaged DNA is not passed on to daughter cells and is important in cancer prevention.

Your cells need sugar to create energy and survive and they get sugar from the food you eat. Once your food is digested, sugar molecules travel through the bloodstream and then will be transported into your cells. Diffusion only allows sugar to be transported into a cell until it reaches equilibrium so how can your cell bring in even more sugar after it has reached an equilibrium
A cell uses a variety of procedures to turn carbohydrates into energy. The initial and most fundamental one is known as glycolysis. Hexose sugars are used to fuel it. This lengthy procedure only expels a modest quantity of energy.
The energy needed by your body to function comes from glucose. The body receives glucose from the consumption of carbs. You get four calories of energy from every gramme of carbohydrates you eat. When you consume carbs, your digestive system uses specialised enzymes to convert them into glucose, a type of simple sugar.
Function of sugar in the body The body uses carbohydrates as fuel to produce energy.
Foods high in carbs are converted by the body into glucose, which can then travel through the bloodstream. For the brain, central nervous system, and red blood cells to operate properly, some glucose is required.

how do the locations where photosynthesis occurs differ in prokaryotes and eukaryotes
Photosynthesis takes place on the folds in prokaryotes and in specialised organelles in eukaryotes. Prokaryotic cells don't have specific organelles or a remote nucleus.
What is photosynthesis?
Plants absorb water (H2O) and carbon dioxide (CO2) from the soil and atmosphere during photosynthesis. Water is oxidised, which means it loses electrons, while carbon dioxide is reduced, which means it receives electrons, inside the plant cell. Water is converted into oxygen and carbon dioxide into glucose as a result. After storing energy within the glucose molecules, the plant releases the oxygen back into the atmosphere.
Chloroplasts, which are tiny organelles found inside plant cells, are there to store solar energy. Chlorophyll, a light-absorbing pigment found in the thylakoid membranes of the chloroplast, is what gives plants their green hue.

How did Mendel's pea plants help us understand genetics?
Mendel's pea plants gave us a clear and straightforward framework for analyzing the inheritance of traits, which improved our understanding of genetics. Pea plants are a good choice for Mendel's research because they can easily self- or cross-fertilize and have a short generation time.
Mendel exploited the distinct and readily observable traits of pea plants in his tests, including seed color, seed shape, and bloom color.
According to Mendel's research, traits are influenced by specific "factors" that are passed from parent to child. He discovered that the presence of two alleles, one inherited from each parent, determines the inheritance of each feature and that one allele can be dominant over the other.
He also discovered that different characteristics are inherited independently of one another and that the probability of an offspring inheriting a specific allele from a parent is 50%. These discoveries laid the foundation for the field of genetics and provided a framework for understanding how traits are passed down from one generation to the next.

Duchenne muscular dystrophy (DMD) is a recessive, sex-linked disorder carried on the X chromosome. If a woman who is a carrier of DMD and a man without the disorder have children, which outcome is possible?
a. All of their sons and half of their daughters could have DMD.
b. Half of their sons and half of their daughters could have DMD.
c.Half of their sons and none of their daughters could have DMD.
d. None of their sons and half of their daughters could have DMD.
Answer:
C. Half of their sons and none of their daughters could have DMD.
Explanation:
DMD is a recessive disorder carried on the X chromosome and it is sex-linked. This means that the gene for DMD is located on the X chromosome and it affects mostly males.
If a woman is a carrier of DMD, it means that she has one copy of the mutated gene and one normal copy, and she does not show any symptoms of the disorder.
If a man without the disorder has children with this carrier woman, half of their sons will inherit the mutated X chromosome from the mother. Therefore, they will have the disorder and half of their sons could have DMD.
Since, Females have two X chromosomes, and therefore, if a daughter inherits the mutated X chromosome from the mother, the second X chromosome will be normal which will help in compensating the effects of the mutant one, hence they will be carrier of the disorder but will not show any symptoms. So none of their daughters could have DMD.
So, the outcome is: C. Half of their sons and none of their daughters could have DMD.
Answer:D
Explanation:
I think it is D because only the mother had it and not the father. I don't think the father could get DMD through sex either. So I think that none of their sons and half the daughters could have DMD because they inherited it from the mother.

The cell bursts when the cell wall of a plant cell is removed by a certain way, then put in distilled water because the cell wall is removed, the cell would get wet, which would cause it to burst..
How do plant cells react to exposure to distilled water?Putting a plant cell in distilled water causes it to become turgid. This is due to a process called osmosis, which causes the plant cell's cytoplasm to swell up and firmly press up against the cell wall as it absorbs water from the hypotonic distilled water.
Cell walls stop excessive endosmosis from happening when water enters the cell, which also prevents plant cells from bursting. If the cell wall were to be broken, water would enter the space and the cell would eventually burst.

explain how the relationship between light and pigment production might serve as a protective mechanism
The relationship between light and pigment production can serve as a protective mechanism for plants and other organisms. Pigments absorb light energy and convert it into chemical energy, which is then used to drive metabolic processes such as photosynthesis.
This allows plants to absorb light and use it to create energy. Pigment production can also help protect organisms from dangerous ultraviolet radiation. Pigments absorb ultraviolet light and prevent it from reaching the cells beneath. This can help protect them from damage caused by exposure to UV radiation.
In addition, the pigments can act as natural sunscreen, reducing the amount of harmful radiation that reaches the organism’s skin. Pigments can also provide camouflage and protection from predators. By changing the colour of their skin, organisms can blend into their environment, making them less visible to predators.

What does water vapor rising include?
Water vapor rising refers to the process by which water molecules in the air become more energetic and move more freely, causing them to rise higher in the atmosphere. This can occur as a result of several different factors, including:
1. Temperature: Water vapor will tend to rise in the atmosphere if it is warmer than the surrounding air. As the water molecules absorb heat energy, they become more energetic and are able to move more freely, causing them to rise.
2. Humidity: Water vapor will also tend to rise in the atmosphere if the air is already saturated with moisture. When the air becomes saturated, any additional water vapor that is added to it will be less likely to stay in the air and will instead tend to condense and fall to the ground.
3. Pressure: Water vapor will also tend to rise in the atmosphere if the air pressure is lower at higher altitudes. As the water molecules rise and the air pressure decreases, they become more energetic and are able to move more freely, causing them to rise further.
Overall, water vapor rising is an important process in the Earth's atmosphere that helps to distribute heat and moisture around the planet and to regulate the Earth's climate.
