Answer:
Since both plants are true breeding, it means that both are homozygous for the allele of the trait, that is flower color. The geranium plant with red flowers can be denoted as RR and the plant with white flowers can be denoted by WW. Since it is not mentioned in the question that which trait is dominant over the other, but one thing is sure that all the offspring will look alike in color, because their genotype will be same, RW.
The punnet square that best describes them is in attached figure, please see.

Answer:
more cell types are needed to perform specialized functions in multicellular organisms
Explanation:
Cells in a multicellular organism differentiate to produce more cells that perform specialized functions. Each cell type in a multicellular organism has special features that enable it to perform a particular function effectively. In plants, cell differentiation occurs at the stem and root. The meristematic cells differentiate into either an epidermal, parenchymal or a vascular tissue depending on location.
Answer:
1. Water
2. Carbon dioxide
3. Sunlight
4. Oxygen
5. Glucose
Explanation:
The above shows the correct answer. The labelled parts have been correctly named.
From the diagram, we can see that the water falls on the soil where it is absorbed by the roots. The leaves of the plant take in carbon dioxide as seen no. 2 and gives out oxygen as seen in no. 4. The plant also absorbs the sun energy. These are needed by the plant for photosynthesis which is a process that leads to the manufacture of glucose and energy.
The main function of the microscope is to see microscopic objects, or small objects so small the naked eye can't see it. It magnifies the object so our eye can see it.
<span>After discovering and improving the microscope, Robert Hooke discovered cells. This is just one example of how it changed the study of organisms. With the microscope, we could see and find microscopic life like bacteria and see the cells, shape, color, and other materials such as the organelles the organisms were made of.</span>
Answer:
Nylon is a strong synthetic fibre, which resists abrasion. Nylon doesn’t shrink or stretch through washing, but it is degraded by ultraviolet light.
Explanation:
Nylon is made when the appropriate monomers (the chemical building blocks which make up polymers) are combined to form a long chain via a condensation polymerisation reaction. The monomers for nylon 6-6 are adipic acid and hexamethylene diamine. The two molecules are combined to create the polymer and water (H2O) is produced as a by-product. The water is removed from the production process as its continued presence stops the creation of more polymer. The polymer chain can be made up of over 20,000 monomer units, connected together via an amide group, which contains a nitrogen atom. The nylon molecules are very flexible with only weak forces, such as hydrogen bonds, between the polymer chains, which tend to tangle randomly. The polymer has to be warmed and drawn out to form strong fibres
