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:
The correct answer is "each of the MHC genes has a large number of alleles, but each individual only inherits two for each gene".
Explanation:
In normal conditions, an individual has only two different alleles for a given gene: one inherited from his mother and the other from his father. However, this does not mean that among humans, there are only two different alleles for each gene. The major histocompatibility (MHC) genes are a clear example of this, since there are multiple combinations for each MHC class. For instance, there are 40 very similar alleles only for the HLA-B27 subtype.
Answer:
The correct option is D. 18 year old male
Explanation:
The epiphyseal plate can be described as a disc of cartilage that is required for the growth of bones. The epiphyseal plates get fused in females at a very early age, most probably between the ages of 13 to 15. In males, the epiphyseal plates fuse a litter later at about 15 to 18 years.
Hence, the presence of epiphyseal plates in the femur would prove that it was present in an 18-year-old male.
All the other options would be false because they won't contain an epiphyseal plate.
Answer:
99% water, sodium chloride, trace amounts of wastes, and vitamin C
Explanation:
Eccrine glands are the main and major sweat glands of our body. These glands are found all over the skin but their density is higher on palm, soles, and head.
99% of the secretion of the eccrine gland is water and in rest 1% it contains sodium, trace amounts of waste and a high amount of vitamin C is lost by the eccrine gland.
As the eccrine gland is responsible for sweating so it helps in thermoregulation in the body. As 99% of secretion is water therefore dehydration and water loss is the major worry during excessive sweating.
