Well, it depends on the purple pea plant. Purple pea plants can have either PP or Pp.
White pea plants always have recessive, so it would have pp only.
So, the expected outcome of the cross would be -
PP x pp or Pp x pp
PP x pp = all the offspring would be purple in colour
or
Pp x pp = half would be purple and the other half would be white
This is originally called a Flatworm. Hope this helps!

Answer:
tumor suppressor gene
Explanation:
A tumor suppressor gene is capable of modulating cellular processes during cell division and/or replication, thereby avoiding uncontrolled cell proliferation and tumor development. For example, the p53 gene is a tumor suppressor gene that encodes a protein (p53) which is well known to regulate critical cellular processes such as, for example, cell cycle arrest and programmed cell death (apoptosis). Moreover, breast cancer genes BRCA1 and BRCA2 are tumor suppressor genes that regulate the repair of damaged DNA through the Homologous recombination (HR) pathway. In consequence, mutations in BRCA1 and BRCA2 genes can increase the risk of developing breast cancer.
Answer:
the questionnaire is incomplete, the options are attached to the graph
correct answer c
Paine's experiment was performed when exrtaer the starfish that was considered a negative predator by feeding on a local mussel, what was expected is that by eliminating the starfish it proliferates but its consequence was that it began to displace other species When the mussels became a predator due to the alteration of the ecosystem, the balance was removed and now the species cannot coexist.
Producers provide primary consumers with the chemical energy they need.
Explanation:
- Producers lie at the first trophic level of the food chain.
- The producers are the green plant which are able to convert the light energy of the sun into chemical energy.
- Thus, they are the key in directing the energy from the ultimate source to the food chain.
- Primary consumers comprise of the herbivore or omnivores which feed on the plants and plant product.
- The only way they could get energy is from the plant directly or indirectly as they cannot photosynthesize.
- Thus. we can conclude that producers provide primary consumers with the chemical energy they need.
