Answer:
The correct Answer is A.
Explanation:
The Flow chart of the Carbon Cycle, will look as follows:
1. Carbon dioxide in the atmosphere.
2. Producers undergo photosynthesis (in this process plants among other producers like algae, use CO2 to produce energy).
3. Consumers eat producers (a primary level of consumer like a rabbit eats the producers or plants).
4. Decomposers return Carbon to the soil and release waste.
And the cycle continues again, by going back to step 1.
Answer:
Carbohydrates.
Explanation:
Carbohydrates are very essential food nutrients that meet out our entire cellular energy requirement. They play a special role of providing energy during exercise and are commonly found is grains (wheat, rice) , fruits, vegetable, milk products and beans. They make human being sharper and provide energy for all their metabolic process with in the body.
Carbohydrates are broken down into simple sugar molecules such as glucose, fructose, and galactose.
Answer: Alanine and glutamine play special roles in the transport of amino groups from the muscle and from other nonhepatic tissues, respectively, to the liver.
Explanation:
MHC Protein
The major histocompatibility complex (MHC) is a set of cell surface proteins essential for the acquired immune system to recognize foreign molecules in vertebrates, which in turn determines histocompatibility.
The main function of MHC molecules is to bind to peptide fragments
derived from pathogens and display them on the cell surface for
recognition by the appropriate T-cells.[1] MHC molecules mediate interactions of leukocytes, also called white blood cells (WBCs), which are immune cells, with other leukocytes or with body cells. The MHC determines compatibility of donors for organ transplant, as well as one's susceptibility to an autoimmune disease via cross reacting immunization. In humans, the MHC is also called the human leukocyte antigen (HLA).
Answer:
Number of bacteria cells = 2621440 cells
Explanation:
The generation time of a bacteria specie is the time it takes for a population of bacteria to double in number. The generation time for most common bacteria is quite short, about 20 minutes to 1 hour.
Bacteria reproduce asexually by binary fission, in which the parent cell divides into two to produce two identical daughter cells.
In the given question, the generation time of the bacterial species is 20 minutes.
The time that have passed from between the time the sandwich was packed at 6:00 am to lunch time by 12:00 pm is 6 hours.
Using the given formula in the hint: number of cells = 2^(ab) × C
Where a = number of times per hour the bacteria reproduces; b = number of hours; C = number of bacteria at the start
a = 60 minutes/ 20 minutes = 3; b = 6; C = 10
Number of cells = 2^(3 × 6) × 10
Number of cells = 2621440 cells
