Answer:
Cross the green-pod plant with a yellow-pod plant.
Explanation:
To determine the zygosity of a particular individual, the best way is to cross it with a phenotypically recessive individual.
Such a cross in which an individual with unknown zygosity possessing a dominant trait is crossed with an individual possessing a recessive trait is termed as a test cross.
Therefore, in the given situation the zygosity of the green pod needs to be determined and the green pod is a dominant character. Further, it is given that a yellow pod is a recessive trait, therefore a test cross can be performed between the green pod and yellow pod, and then the offsprings can be observed.
if the offsprings are all phenotypically dominant then the green pod is homozygous and if there are phenotypically recessive offspring also present then the green pod is heterozygous genotypically.

In humans, the pelvis and the femur, or thighbone, are involved in walking. In whales, the pelvis and femur shown in this figure represent...
Answer:
vestigial structures
Explanation:
A "vestigial structure" or "vestigial organ" are defined as the organs that no longer have any function in the organisms' body but had an important role in past.
<em>Pelvis and femur are thigh bones in humans which helps them in walking but in whale's pelvis and femur are considered as vestigial structures. </em>
The pelvis and femur in whales, are the inherited structure from ancestors and shows evidence for evolution on the basis of natural selection.
Hence, the correct answer is vestigial structures.
Explanation:
Physical weathering is the disintegration of rocks into smaller chunks in nature.
Water is one of the agents that causes physical weathering.
- during periods of low temperature especially the summer, water usually collects within rock cavities.
- When temperature drops, the water freezes and expands.
- Periodic freezing and thawing of ice leads to physical weathering.
- Also, in tropical regions, alternate wetting and drying of rocks occur.
- When a rock is wet, it absorbs more water and it volume expands.
- Drying occurs and it loses the water.
- This continuous process leaves cracks in rock.
