What are the primary structures for modifying and packaging of cellular secretions for export from the cell? a. lysosomes b. mitochondria c. Golgi bodies d. chloroplasts e. ribosomes

Answers

Answer 1

Answer: Answer:

c. Golgi bodies

Explanation:

The Golgi apparatus, often referred to as the Golgi bodies, plays a crucial role in modifying and packaging cellular secretions for export from the cell. It is a cellular organelle responsible for processing, modifying, and sorting proteins and lipids that are synthesized in other parts of the cell, such as the endoplasmic reticulum (ER).

Here's how the Golgi apparatus works:

Modification: Proteins and lipids synthesized in the ER are initially in an immature, non-functional form. The Golgi apparatus modifies these molecules by adding specific chemical groups, such as carbohydrates (glycosylation), to them. This modification is essential for their proper function.

Sorting: The Golgi apparatus also sorts these modified molecules into vesicles, which are small membrane-bound sacs. These vesicles can contain various substances, including enzymes, hormones, or other proteins that need to be exported or sent to other parts of the cell.

Packaging for Export: Once sorted, the Golgi apparatus packages these vesicles for export. They can merge with the cell's plasma membrane and release their contents outside the cell through a process called exocytosis. This allows cellular secretions to be transported outside the cell to perform their functions.

In summary, the Golgi apparatus is responsible for modifying, sorting, and packaging cellular secretions for export, making it a crucial organelle in the cell's secretory pathway. This process ensures that proteins and other molecules are correctly processed and delivered to their intended destinations within or outside the cell.

What is the purpose of the cell cycle

Answers

The purpose of cell cycle is to replicate those parents cell by dividing into cells but maintaining the original cell genome. The cell cycle composes of two phases, the interphase wherein the cells are still growing and preparing for mitosis, the other phase is mitotic phase where in the cells will separate to create daughter cell.

Answer:

D - growth, repair, and reproduction of cells

Explanation:

An Overview of the Cell Cycle. The most basic function of the cell cycle is to duplicate accurately the vast amount of DNA in the chromosomes and then segregate the copies precisely into two genetically identical daughter cells. These processes define the two major phases of the cell cycle.

A static character _____.has only one or two developed traits
is not influenced by events around him
changes, or grows, according to the occurrence in his life

Answers

A static character is not influenced by events around him. It is the second main type of the character in the story that does not change and stays the same from the beginning until the end. It is the exact opposite of a dynamic characters, someone that changes based on the events and the circumstances of the story. The actions and even the decisions made by a static character stays true to its personality from the start until the story draws to a close.

Within the water cycles, where do individual water molecules stay for the least amount of time?A: in the atmosphere

B: in the ocean

C: in deep groundwater

D: in shallow groundwater

Answers

Answer:

A: in the atmosphere

Explanation:

As the air is a mixture of gases and the air is continuously in motion as the water molecules are then evaporated or quickly get concentrated and condense and hence they get transformed very quickly thus for the least amount of time the water molecule is present in the air.

The air current picks and drops the molecules to far and distance off place and hence they tend to remove the molecules or shift them from one place to another.

In peas, yellow seed color (Y) is dominant to green seed color (y). A homozygous green pea plant is crossed with a heterozygous yellow pea plant. What is the predicted phenotypic ratio of the offspring? A.50 percent yellow, 50 percent green B.50 percent Yy, 50 percent yy C.100 percent yellow, 0 percent green D.100 percent Yy, 0 percent yy

Answers

Steps:
1. Do a pun-net square
y y
Y
y
2. Your offspring would be Yy, Yy, yy, yy
3. Your answer would be B

A homozygous green (yy) pea plant is crossed with a heterozygous yellow (Yy) pea plant. The phenotypic ratio of the offspring is 50 percent Yy and 50 percent yy.

Further Explanation:

Genotypes help in the genetic makeup of any individual. Phenotype describes as a physical characteristic of an individual. The genotype is responsible for the phenotypes of any individual. If two copies of the same alleles present in an organism, its genotype is called homozygous. If two copies of different alleles present in an organism, its genotype is called heterozygous.

When a homozygous dominant individual is crossed with the homozygous recessive individual the resultant offspring has the genotype which is heterozygous and phenotype which is dominant. All possible genotypes of the parent as well as offspring are graphically represented in a Punnett square.

In the given punnet square below, the parent homozygous green plant having a genotype yy is crossed with the parent heterozygous yellow plant having a genotype of Yy. The resultant offspring of filial generation tends to be 50 percent of Yy which means heterozygous and 50 percent yy which means homozygous.
