Cytokinesis – division of the cytoplasm resulting in two identical d_______________ cells.

Answers

Answer: daughter

Explanation: Cytokinesis results in the division of cytoplasm in a parental cell, creating 2 identical daughter cells.

Hope this helps!

Cytokinesis, the division of the cytoplasm resulting in two identical daughter cells, is caused by the mitosis process, as here the two daughter cells get an equal amount of the genetic contents.

What is the significance of cytokinesis in mitosis?

It is very important in mitosis because it aids in the division of two cells from one cell during the cell division process and results in the formation of two genetically identical daughter cells; without cytokinesis, the chromosomes would remain in the same cell, resulting in mutation as multinucleated cells are formed in such a process.

Hence, cytokinesis, the division of the cytoplasm resulting in two identical daughter cells, is caused by the mitosis process, as here the two daughter cells get an equal amount of the genetic contents.

gene is a segment of DNA on a chromosome. How are genes related to the proteins made by a cell?

Answers

Answer:

The DNA in genes is transcribed into RNA and translated into proteins

Explanation:

The sequence of DNA in a gene is transcribed into a messenger RNA (mRNA). This sequence of this mRNA is translated into a sequence of amino acids that form a protein.

The sequence of DNA in a gene directly affects the amino acids, and therefore the structure and function of, a protein.

Answer:

The structure of the genes in a cell determines the structure of the proteins made by the cell.

How do limiting factors determine the carrying capacity of an ecosystem ?

Answers

Answer:

Limiting factors determine carrying capacity. The availability of abiotic factors (such as water, oxygen, and space) and biotic factors (such as food) dictates how many organisms can live in an ecosystem. Carrying capacity is also impacted by the availability of decomposers.

Explanation:

Carrying capacity is determined by limiting variables. Limiting factors can be divided into two categories: those that depend on the density and those that don't.

What are the limiting factors?

Limiting factors can be divided into two categories: those that depend on the density and those that don't. These names are accurate in their meanings.

No matter how big or little, expanding or contracting, the population is affected by density-independent causes. For instance, regardless of the density of any one population, a wildfire that burns through a dense forest in the Everglades has a significant effect on every population in the area.

The majority of density-independent limiting variables fall into the abiotic (nonliving) group, which includes wildfire. Hurricanes, pollution, and seasonal climate extremes are other density-independent variables.

Therefore, Carrying capacity is determined by limiting variables. Limiting factors can be divided into two categories: those that depend on the density and those that don't.

what makes angiosperm more advance than gymnosperm​

Answers

Answer& Explanation:

Angiosperm is more advanced due to the mechanism of protection it has since developed as opposed to its predecessor, gymnosperm. Angiosperms could be deemed the inventors of animal-mediated pollination or dispersal, whereas gymnosperms mostly depend on wind-mediated pollination (which is far more of a gamble than animal mediated).

1) Angiosperms seeds are enclosed in fruits, which increases the chances of dispersal by either wind, water, or animals. Animals can eat the fruit and disperse the seeds via feces or by brushing the fruit off of their fur coats new areas of the terrain.

2)The development of flowers. Flowers are especially important because depending on the flower it can attract a set species of animals in order for pollination to occur. That species of animal could only focus on those few flowers and would allow the female part of the flower to receive pollen (produced by the male part of the flower) from all over the place. This theory is also applicable to animal mediated fruit dispersal.

Flowering plants mature more quickly than gymnosperms, and produce greater numbers of seeds. The woody tissues of angiosperms are also more complex and specialized. Their seeds are enclosed in a fruit for easy dispersal by wind, water, or animals.

Using information from the diagram, state one reason why the movement in the third image represents active transport

Answers

Answer:

A protein or ion has passed through the "pump" or carrier proteins and move within the cell.

Nvm short and sweet ;)

Further info..

To move substances against a concentration or an electrochemical gradient, the cell must use energy. This energy is harvested from ATP that is generated through cellular metabolism. Active transport mechanisms, collectively called pumps or carrier proteins, work against electrochemical gradients. With the exception of ions, small substances constantly pass through plasma membranes. Active transport maintains concentrations of ions and other substances needed by living cells in the face of these passive changes. Much of a cell’s supply of metabolic energy may be spent maintaining these processes. Because active transport mechanisms depend on cellular metabolism for energy, they are sensitive to many metabolic poisons that interfere with the supply of ATP.
