Why is algae able to endure photosynthesis when grown under green light? (has something to do with absorbing the color green)
Chlorophyll makes plants and algae appear green because it reflects the green wavelengths found in sunlight, while absorbing all other colors.
However, chlorophyll is not actually a single molecule. There are 6 different chlorophylls that have been identified. The different forms (A, B, C, D, E and F), each reflect slightly different ranges of green wavelengths. Chlorophyll A is the primary molecule responsible for photosynthesis. That means that chlorophyll A is found in every single photosynthesizing organism, from land plants to algae and cyanobacteria. The additional chlorophyll forms are accessory pigments, and are associated with different groups of plants and algae and play a role in their taxonomic confusion. These other chlorophylls still absorb sunlight, and thus assist in photosynthesis. As accessory pigments, they transfer any energy that they absorb to the primary chlorophyll A instead of directly participating in the process. Chlorophyll B is mainly found in land plants, aquatic plants and green algae. In most of these organisms, the ratio of chlorophyll A to chlorophyll B is 3:1. Due to the presence of this molecule, some organizations will group the green algae into the Plant Kingdom. Chlorophyll C is found in red algae, brown algae, and dinoflagellates. This has lead to their classification under the Kingdom Chromista. Chlorophyll D is a minor pigment found in some red algae, while the rare Chlorophyll E has been found in yellow-green algae. Chlorophyll F was recently discovered in some cyanobacteria near Australia. Each of these accessory pigments will strongly absorb different wavelengths, so their presence makes photosynthesis more efficient.
What happens when a mutation occurs during the formation of gametes in a parent sex cell?
Answer:
if it's a silent mutation, nothing significant will happen, but if it's a frame shift mutation, it can make the baby deform.
Answer: most mutations will have no effect, although in rare cases an abnormal foetus may develop and even more rarely the embryo may be non-viable.
Explanation: A mutation at this stage is probably due to a random result of an external effect (cosmic ray for example) and probably a change in one nucleotide (a single nucleotide polymorphism). It is unlikely that the mutation will be an insertion, deletion or inversion.
Whatever the mutation, it is unlikely to occur in the relatively small proportion of coding DNA. If it does occur in coding DNA it is still unlikely to be at a critical codon. If it does occur at a critical codon, it may still code the the same amino acid, particularly if it is a third nucleotide.
There is a low probability that the mutation will prevent the formation of a fully functional protein, by altering a critical amino acid or altering the frame by changing a stop codon, or creating a stop codon, or altering a promoter region. Even in this case, any error can be avoided if the other allele is intact.
It is possible, however, that a mutation could result in a development abnormality (cystic fibrosis is an example), or a non-viable embryo.

3.Whenever the surfaces in contact tend to move or move with respect to each other, the force of friction comes into playRequired to answer. Single choice.
Answer:
The correct answer is - Friction occurs irrespective of the state of the matter.
Explanation:
Friction is the force that takes place when there are two different surfaces slide or moves across one another and causes a resistance between surfaces. The friction always takes place opposite direction to the other surface direction of moving.
Pushing a book on a table, pulling a heavy cart on road all are examples of friction. The friction that occurs in liquids and gases is called fluid friction. Thus, the friction takes place irrespective of the state of the matter.

I believe the answer is parasitism. The cuckoo bird uses sneaky tactics to trick the warbler into doing the parenting for them
Answer:
I believe the answer is parasitism
Explanation:
it makes the most sense within this scenario. The cuckoo bird invades another oragnism's way of life, harms the other eggs in the process, and lives off of the shelter and nurtrients that would have been the baby warblers given by the warbler mom.
mutualism: symbiosis that is beneficial to both organisms involved
commensalism:an association between two organisms in which one benefits and the other derives neither benefit nor harm.
parasitism:the practice of living as a parasite in or on another organism.
How is the function of a leaf different from that of a stem or root?
Answer:
the leaf of a plant takes the sunlight and converts it into food the stem and roots are for stability and for water absorbtion
Explanation:
Answer:
Seed plants have three main parts that serve specialized functions: roots, stems, and leaves. Roots help to anchor the plant in the ground as well as absorbing water and nutrients from the soil. ... Leaves carry out photosynthesis, which is the most important way that plants produce the energy to live.
Explanation:
In cats grey color (G) is dominant to white color (g). If a white female has kittens with a heterozygous male, and the mother is showing that she will be having 9 Kittens, how many kittens would you expect to be white? (Round down to the nearest whole number, you cannot have partial kittens)
Answer:
Rounding down to the nearest whole number, 5 Kittens will be white.
Explanation:
Available data:
grey color (G) is dominantwhite color (g) is recessivewhite female, ggheterozygous male, Gg9 KittensCross:
Parental) Gg x gg
Phenotype) Grey White
Gametes) G g g g
Punnet square)
G g
g Gg gg
g Gg gg
F1) Genotypes:
1/2 = 50% will be Gg
1/2 = 50% will be gg
Phenotypes:
1/2 = 50% will be Grey (Gg)
1/2 = 50% will be white (gg)
To calculate the number of kittens that will be white, we need to consider the proportions of cats that will be white in the F1 and that the total number of kittens is 9. So
100% of the progeny ------------------------------- 9 kittens
50% of the progeny----------------------------------X = (50 x 9)/100 = 4.5 kittens ≅ 5 Kittens
A cat can not have 4.5 kittens, so we must round down to the nearest whole number. 4.5 ≅ 5 Kittens
Hey, can someone please help, what's a good hook for a Biology reflection essay?
Answer: quote from a famous biology scientist
Explanation:
a quote from Rachel Carson which I think is beautiful, "The more clearly we can focus our attention on the wonders and realities of the universe about us, the less taste we shall have for destruction."
in humans, dimples are dominant to no dimples. cross a woman with no dimples with a man who is heterozygous for dimples. determine the phenotypic and genotypic ratio of their offspring. show a punnett square to support your answer
Genotype: 50% Aa and 50% aa
Phenotype: 50% Dimples and 50% no dimples
Explanation: Using a punnet square, we can figure out that the mother is recessive and the father is heterozygous. Putting the mother at the top of the square and the father on the side, you end up with the results above by crossing each square with the corresponding letters. It's okay if the letters end up backwards. Just be sure to face them the right direction, capitals being first once you finish.

How does Sea walnuts impact humans?
How to stop Sea Walnuts from spreading and How Sea walnuts can be managed?
3 benefits that will occur if Sea walnuta is removed.
Please helo me I have no idea how to answer these.
Answer: Sea walnuts are marine invertebrates. They belong to the genus Mnemiopsis.
Explanation:
These animals have stinging tentacles like jelly fish and they often cast up or come to the sea shores where if they come in contact with humans can harm them by stinging.
The barrier if kept along the side of the sea shore and not allowing humans to reach to the shore can help in preventing the harm from these animals. The introduction of the predatory animals in the sea can also help in reducing their population.
The three benefits for removing the sea walnut:
1. The population of other species will increase as sea walnut is an invasive species.
2. The balance of the marine ecosystem can be maintained.
3. Humans can be protected from the harm caused by these animals.

How do animals get nitrogen that is stored in the soil?
O A) Animals do not take in the nitrogen stored in the soil.
O B) Bacteria change the nitrogen into a gas that the animals breathe.
OC) Plants ab orb the nitrogen from the soil and animals can eat the plants.
O D) The animals can eat the soil and absorb the nitrogen through their digestive system
Answer: C) Plants absorb the nitrogen from the soil and animals can eat the plants.
Heterotrophs, specifically herbivores and omnivores, are animals that eat plants (autotrophs) to get the nutrients they need. Those that eat the plants get the nitrogen from the plant that has absorbed it from the soil. Omnivores and carnivores eat the herbivores to get nitrogen that way. For more more information, take a look at the nitrogen cycle.
