Paramecium caudatum. This is an example of: parasitism. competitive exclusion. mutualism. commensalism. Many plant species
The given question says that a student has constructed a model of cellular transport using fences and several gates.
This model can be used to demonstrate the cellular transport.
The gates of the fences can be supposed as the protein pumps and the other fence demonstrates the lipid bilayer.
Let’s suppose in the fence, there are many cattles, and outside, there are less cattles, but the student open the gate and bring more cattles inside the fence. In this case, the transport of the cattles is similar to the active transport of the molecules using protein pumps. At cellular level, the energy for the active transport is provided by ATP molecules.
Now, let’s say, the student wants to feed the cattles with some nutrition rich food, which can help in maintaining the health of the cattles. The student fills his car with the cattle food and he enters inside the fence through gates. In this case, the food was not present in the fence, but was abundant in the outside environment, so, the diffusion would occur. But food cannot come self, without help of others, so, the movement is facilitated by the car, as it is done by the carrier proteins. Hence, it is an example of facilitated diffusion.
Answer:
Platismatia is a genus of lichens that often is found in forests. Lichens may be beneficial for forests because they provide food and nutrients for other species by fixing atmospheric nitrogen
Explanation:
The lichens are the result of mutualism between photosynthetic organisms (algae or cyanobacteria) and fungi species.
I) Alleles is the alternative form of a gene or in other terms the variant form of a gene. If there are two alleles at a locus p and q are used to represent their frequencies. Frequencies of all alleles in a population will add up to 1.
Therefore, in this case if red allele CW is p=0.7, then the frequency of the white allele in this population (q) is 0.3.
ii) From the punnet square the expected genotypes frequencies in the offspring generation will be 0.49 CRCR (red flowers, o.42 CRCW (pink flowers) and 0.09 CWCW (white flowers).
Answer:
The biology Molecules that will.be present in what she consumed are Carbohydrates from unbuttered bread, vitamins green spinach, Fat and oil or lipids from sunflower seeds, proteins...
The Carbohydrates is processed into glucose, proteins is processed into amino acids, lipids is processed into fatty acids and glycerol.
Explanation:
From the food consumed, The biology Molecules that will.be present in what she consumed are Carbohydrates from unbuttered bread, green spinach contains vitamins like vitamin K, vitamin A, vitamin C, vitamin B12 , minerals like magnesium, iron, Fat and oil or lipids from sunflower seeds, proteins...
The Carbohydrates is processed into glucose after enzymes like salivary amylase acts on it from the chewing and in the stomach which produces glucose which makes it easily absorbable , proteins is processed into amino acids by the activity of hydrochloric acids and protease that processed it into amino acids, lipids is processed into fatty acids and glycerol by the activities of the enzymes lipase.
The minerals and vitamins present are in a way they can be absorbed.
