Answer:
The correct answer will be option-B
Explanation:
The environment of the stomach is acidic in nature maintaining value less than seven as it kills the microbes and helps activate the pepsin to digest the proteins.
The acidic nature of the gastric juice does not affect the stomach as the mucosa layer of the stomach secretes mucous and the if the cells get affected then the cells are repaired by the process of mitosis taking in the epithelial cells.
Thus, Option-B is the correct answer.
The first box is migration
The second box is the northern regions have become warmer because of climate change
Answer:
The correct answer is - 6.25 mAh.
Explanation:
According to the Ohms law of power, the current of a source can be found with the help of the formula
I = V ÷ R
where, I (amps) = V (volts) ÷ R (Ω)
By placing the value given:
I = 5.00/800
I = 6.25 mAh
The current output of the charger would be 6.25 mAh
Answer:
D. 1 BB : 2 Bb : 1 bb
Explanation:
This question involves a single gene coding for fur color in guinea pig. Black fur (B) is dominant over white fur (b). This means that, as stated in the question, if a black fur parent (BB) is crossed with a white fur parent (bb), a 100% heterozygous offspring (Bb) with black fur will result.
If two heterozygous guinea pigs are crossed i.e. Bb × Bb, the following gametes will be produced by each heterozygous parent:
Bb = B and b
Using these gametes in a punnet square (see attached image), offsprings with the following genotypic ratio will be produced:
1 BB : 2 Bb : 1 bb
BB and Bb = black fur guinea pigs
bb = white fur guinea pigs
Answer: herbivore, eukaryote, primary consumer
Explanation:
The red squirrel can be described by the following features.
1. Herbivore: A herbivore is an animal which is dependent upon the plant and their products for it's food requirement. Here, the red squirrel is the herbivore because it is dependent upon the spruce tree seeds for their food requirement.
2. Eukaryote: A eukaryotic organism is the one which has well define nucleus and encloses the genetic material in the nucleus. The red squirrel is a complex eukaryotic organism.
3. Primary consumer: In a food chain a primary consumer is an organism which is dependent upon plants and their food products for energy and food needs. The red squirrel is the primary consumer this is because of the fact that it consumes on the seeds of the spruce trees.
