Answer:
A phosphate backbone is the portion of the DNA double helix that provides structural support to the molecule. DNA consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups.
If two heterozygous individuals are crossed, the results of the cross are as follows:
- SS - spotted condition
- 2 Ss - Spotted condition
- ss - non-spotted condition
<h3>What is an Heterozygous Cross:</h3>
According to this question, the gene coding for spotted condition. The allele for spotted condition (S) is dominant over the non-spotted condition (s).
If two heterozygous Dalmatian dogs are crossed i.e. Ss × Ss, the allele combination for each gamete is as follows:
The following offsprings will be produced:
- SS - spotted condition
- 2 Ss - Spotted condition
- ss - non-spotted condition

I think simple diffusion is a former of active transport
Answer:
The activity which causes the least amount of wetland and estuary degradation when it occurs near the coast is:
A. dune grass rehabilitation
Explanation:
This is actually a rehabilitation effort, unlike the other three options that cause land degradation. A dune grass rehabilitation accretes sand and minimizes the rates of beach erosion. The program tries to protect coastal infrastructure and upland properties from storm damage by planting vegetation, fencing off sensitive areas, blocking storm surge, creating dune walkways, and absorbing wave energy. During dune grass rehabilitation, activities that adversely affect the dunes are avoided.
