A) proteins are made of amino acids ( if you want to describe it more you can talk about the central dogma, dna to mRNA then mRNA to amino acids and amino acids to proteins. and you can talk about the structures of dna, primary secondary tertiary quaternary). nucleic acids are made of nucleotides ( cytosine (C), thymine (T), adenine (A), guanine (G))
Answer:
Both the PKA and IP3 levels increases. Hence, the correct answer is a and b.
Explanation:
Forskolin refers to a drug that increases the levels of cAMP or cyclic AMP by stimulating the enzyme adenylyl cyclase. The cAMP is an essential secondary messenger that ensures proper biological response of cells to hormones and other signals and also takes part in communication between the cells.
When Forskolin increases the levels of cAMP, it will stimulate the enzyme PKA or protein kinase A and at the same time also enhances the intracellular concentration of Ca2+ and IP3 (inositol 1,2,5 triphosphate).
<span>Higher amounts of nitrogenous compounds will increase algal blooms, leading to less available oxygen in the water, and decrease biodiversity.
--------
Let's take a look at each option and consider them in light of our knowledge.
1. These compounds will combine into larger molecules as they interact in the nitrogen cycle and become food for fish and other animals, increasing biodiversity.
* This has some problems. Yes, the fertilizers will cause an increase in the food supply, but that doesn't spontaneously cause an increase in biodiversity. The only way to increase the biodiversity is to introduce new organisms. And this isn't such a mechanism. I won't pick this choice.
2. The water cycle will remove excess fertilizer naturally through evaporation, with no impact on biodiversity.
* There's some issues here as well. Think about how much fertilizer runoff is considered a pollution issue. If this option were true, then we wouldn't be seeing so many news articles complaining about fertilizer running causing pollution problems. So this answer isn't any good either.
3. Nitrogenous compounds will be recycled into carbon compounds to create new organisms and increase biodiversity.
* Still running into the "spontaneous increase in biodiversity" issue here. How would more carbon compounds suddenly increase the biodiversity? This answer isn't any good either.
4. Higher amounts of nitrogenous compounds will increase algal blooms, leading to less available oxygen in the water, and decrease biodiversity.
* This is a real problem. Some might think that "Algae is a plant. Plants produce oxygen. Why would more algae cause the oxygen supply to decrease?" Well, the answer is pretty simple. Individual algae cells don't live very long. So you have a log of algae being produced. Releasing oxygen to the air, and then dying. And the dead algae then proceeds to decay, which does consume dissolved oxygen in the water. Which does cause the death of fish and other animals that are dependent upon that dissolved oxygen. And that does reduce the biodiversity in the area. So this is a reasonable and correct answer.</span>
Answer:
<u>Nutrition and health benefits</u> are the most likely motivation ,if a person decides to switch from drinking freshly squeezed orange juice to calcium-enriched orange juice after a yearly checkup,
Explanation:
As the Calcium enriched orange juice contains calcium almost equal to that of milk , hence it is an essential mineral which helps in building and maintaining strong bones and teeths.
It is also an excellent source of vitamin D helping the body to absorb more calcium . Thus providing excellent nutrition and health benefits.
Hence <u>Nutrition and health benefits</u> are the most likely motivation
Answer:
The correct answer will be-
1. Genotype of parents (gametes)
2. Genotype of offsprings
Explanation:
Punnett square is the simple graphical way of understanding and predicting the mathematical probability of the inheriting traits of individuals developed by the Reginald Punnett in the 20th century.
The method was used by the Gregor Mendel in his experiments on pea to understand and predict the inheritance pattern.
The Punnett square is constructed by drawing grid perpendicular lines and then putting the genotype or the genetic contribution of one parent on the top side and another parent on the other side. Calculating the genotype of offsprings is represented inside the grid lines.
