B. Packages and redistributes proteins.  

The Golgi apparatus is the distribution and shipping department for the cell's chemical products. It is a special organelle found in the cytoplasm of the eukaryotic cell, it functions in the modification of proteins after they are synthesized. It modifies proteins and fats built by rectums on the endoplasmic reticulum and prepares them for export as outside of the cell. Modification and secretion are major functions of Golgi.

Which disappears more rapidly from a population, a deleterious dominant allele or a deleterious recessive allele?
Allisa [31]

Answer:

Selection is a directional process that leads to an increase or a decrease in the frequency of genes or genotypes. Selection is the process that increases the frequencies of plant resistance alleles in natural ecosystems through coevolution, and it is the process that increases the frequencies of virulence alleles in agricultural ecosystems during boom and bust cycles.

Selection occurs in response to a specific environmental factor. It is a central topic of population and evolutionary biology. The consequence of natural selection on the genetic structure and evolution of organisms is complicated. Natural selection can decrease the genetic variation in populations of organisms by selecting for or against a specific gene or gene combination (leading to directional selection). It can increase the genetic variation in populations by selecting for or against several genes or gene combinations (leading to disruptive selection or balancing selection). Natural selection might lead to speciation through the accumulation of adaptive genetic differences among reproductively isolated populations. Selection can also prevent speciation by homogenizing the population genetic structure across all locations.

Selection in plant pathology is mainly considered in the framework of gene-for-gene coevolution. Plant pathologists often think in terms of Van der Plank and his concept of "stabilizing selection" that would operate against pathogen strains with unnecessary virulence. As we will see shortly, Van der Plank used the wrong term, as he was actually referring to directional selection against unneeded virulence alleles.

In fast-twitch oxidative-glycolytic fibers, their rapid increases in force rely on the ________ activity where rapid relaxation
Kitty [74]

Answer:

1. myosin ATPase

2. Ca2+-ATPase

Explanation:

ATPase activity of myosin head hydrolysis ATP and energize the myosin head. The energized myosin head forms cross bridges to facilitate the power stroke of muscle contraction. The fast-twitch oxidative-glycolytic fibers have the ability to produce ATP by aerobic respiration.  

These fibers have the  ATPase in their myosin heads that hydrolyze ATP three to five times faster than the myosin ATPase in slow fibers. This ensures the faster speed of contraction of these fast-twitch muscle fibers.

During their relaxation, Ca2+ ATPase pumps the calcium ions back to the sarcoplasmic reticulum. As the level of Ca2+ ions in the sarcoplasm decreases, calcium ions are released from troponin. Tropomyosin is allowed to cover the myosin-binding sites on actin and the muscle fiber relaxes faster.

The easiest type of business to start is a sole proprietorship
klio [65]

Answer:

There is no correct answer.

Explanation:

Different circumstances regarding how you operate your company and what kind it is.

Also, with sole proprietorships, it may be hard to manage liabilities, as the owner is <em>personally</em><em> </em>responsible for any liabilities. It is also hard to procure funding for your company.

However, it is simple to incorporate and allows for high flexibility, which may be what you mean by "easiest type ... to start".
