Roman55 [17]

Answer:

B) If two non functional copies are inherited, the pea will be wrinkeld.

Explanation:

The gene for starch debranching is one of the genes that regulate more than one genetic trait. The starch debranching gene also regulates the seed shape in peas. The gene has two alleles. The allele B is completely dominant over allele "b" with respect to seed shape. Both homozygous and heterozygous dominant genotypes (BB and Bb) produce smooth seeds while homozygous recessive genotype (bb) imparts wrinkled shape to the seeds.

Cells can make proteins that need to be transported out of the cell and moved to another part of the body. Cells also make carbo
alex41 [277]

Answer:

The proteins will be transported through exocytosis; the carbon dioxide will diffuse through the membrane.

Explanation:

Diffusion is the passive transport of substances down their concentration gradient. The process moves the substances from the region of higher concentration to that of lower concentration. CO2 is a small molecule and does not have any charge. Small, uncharged molecules can diffuse through the lipid bilayer of the cell membrane. Therefore, CO2 can exit a cell by simple diffusion.

On the other hand, proteins are too large to be transported by diffusion across the cell membrane. The proteins are transported by exocytosis. During exocytosis of proteins, membrane-bound vesicles are formed inside the cell. These vesicles carry proteins in them and are called secretory vesicles. The membrane of the vesicles fuse with the cell membrane of cells and transport the proteins outside the cell.

Social cognitive theory proposes that changing a behavior is a function of individual characteristics. True or False
sertanlavr [38]

Answer:

The answer is: False.

Explanation:

Social cognitive theory stands that portions of an individual's knowledge acquisition can be related to <em>observing others within the context of social interactions. </em>

When people observe a model performing a behaviour and the consequences of that behaviour, they remember the sequence of events and <em>use this information to guide subsequent behaviors</em>.

The theory says that people do not leatn new behaviours solely by trrying them and either succeding or failing, but upon the replication of the action of others.

I hope it works!
