Answer: During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose
Explanation:
Answer:
Temperatures gradient
Explanation:
There are distinct temperature gradient differences in the layers of atmosphere usually due to the main air molecule composition of the layers, the density of the molecules. The Troposphere the lowest layers is the densest and temperature decreases with increase in altitude. The stratosphere, on the other hand, has an increase in temperature with increase in altitude. Temperatures decrease with altitude in the mesosphere while the parameter increases with altitude in the thermosphere.
Answer:
There is no image showing the shape of an enzyme, however, the question can still be answered based on basic understanding. The answers are;
- Less binding of substrate
- won't follow the lock-and-key pattern of enzyme binding
Explanation:
An enzyme is a biological catalyst that regulates the rate of chemical reactions in living systems. Enzymes are proteinous in nature and every protein is made up of an amino acid sequence. The amino acid sequence forms a three-dimensional shape that determines the functionality of the enzyme.
Enzymes catalyze reactions by binding to their substrates in a lock and key pattern. This makes enzymes substrate-specific. If the enzyme's normal shape changes, the following will occur:
- Less binding of substrate
- won't follow the lock-and-key pattern of enzyme binding.
Answer:
Option-D
Explanation:
In the given question the genotype of parental allele is- AbaB X AbaB. The alleles formed will be- AB, Ab,aB, ab in which the crossover allele will be AB and ab.
1. Unlinked genes
Now of these alleles are unlinked then the alleles will assort independently of each other therefore performing the punnett square we will get dihybrid ratio as 9:3:3:1 in which
1. A_B_ are 9
2. aaB_ are 3
3. A_bb are-3
4. aabb- 1
Since the crossover allele are AB and ab therefore A_B_ are 9 and aabb- 1 represent recombinant genotype.
2. Linked genes
When the genes will be linked then chances of crossing over will be reduced as a result of which only two type of allele will be formed which are- Ab and aB and the recombinant frequency will become less.
Crossing these allele will form Aabb
, AaBb
, AaBb and aaBB genotypes.
The recombinant ratio will decrease as A_B_ is 2 and aabb is not present.
Thus, option-4 which states that the unlinked ration is 9:3:3:1 and linked ratio is <9: >3: >3: <1 is correct.
