The genotype for the F1 generation is PURPLE PETALS.
In cross breeding, the offspring of the original generation in a cross are called F1 generation. When two breeding of a particular living organisms are crossed, then the F1 generation will be all the same.<span />

All of the offspring will be heterozygous, meaning they'll have both a P and p allele (Pp), and all will display the dominant allele, P, meaning they will all have purple petals. 

The phenotype for the F1 generation, therefore, is purple petals

Sheets composed of two layers of amphipathic molecules arranged with the hydrophilic groups on the surface and the hydrophobic g
Lera25 [3.4K]

Answer:

D) bilayer membranes

Explanation:

Two lipidic bilayers compose the cell membrane. There are also proteins and glucans incrusted in between. Lipids are amphipathic molecules with hydrophilic heads -negatively charged phosphate group- and hydrophobic tails. Lipids are arranged with their hydrophilic polar heads facing the exterior and the interior of the cells, while their hydrophobic tails are against each other, constituting the internal part of the membrane. Membranes are fluid, which means that the composing molecules can move through them.

Lipids can easily change places with other neighboring lipids by lateral diffusion in the same layer. This is passive diffusion, which means that it does not need energy to happen.

Lipids can also diffuse transversally to the other layer but not as easily as lateral diffusion. Jumps between monolayers are infrequent as the lipidic polar heads meet the fatty acid barrier.

There are also other lipidic movements as rotational diffusion that imply the rotation of the molecule.

11. Explain the importance of having a cell's digestive enzymes enclosed inside lysosomes?
olya-2409 [2.1K]

Answer:

The low pH of the lysosome is maintained by membrane proteins that pump protons (H + ions ) from the cytosol into the lysosome. ... Although it may seem dangerous for cells to contain enzymes that can digest most biological molecules, the contents of the cell are doubly protected from the digestive enzymes of the lysosome.

Increase or decrease ?
Radda [10]

Answer:

Increase

Explanation:

Crossing over is the process by which genetic information is exchanged between two homologous chromosomes

Independent assortment describes the way in which traits are inherited: i.e. different alleles on different chromosomes are inherited independently of one another (in a simple example, a tall green plant can cross with a yellow small plant to make a tall yellow plant or a small green plant - the two traits aren't inherited together.

Therefore, both of these increase the amount of variety present in the gamete, as they both generate new combinations of alleles to pass on to the next generation.
