O que é membrana plasmatica?

1 answer:

6 0

A membrana plasmática é basicamente uma borda entre o interior de uma célula e seu exterior. A membrana regula o que entra e sai da célula e é necessária para a sobrevivência da célula. sem ele, todo o conteúdo da célula se espalharia. Isso seria ruim. Cada célula tem uma membrana, assim como as organelas dentro da célula.

2.tidally

3.spin

4.Kuiper

5.A solar nebula forms when the gas and dust are pulled together in a spinning disk. Particles began to clump together due to gravity, and larger chunks of material exert more gravity on nearby dust and gas. These chunks of material grew faster and formed planets or moons. Denser elements such as iron settled closer to the center of the solar nebula.

Development and Applications of a High Throughput Genotyping Tool for Polyploid Crops: Single Nucleotide Polymorphism (SNP) Array.

Polypoid species play significant roles in agriculture and food production. Many crop species are polyploid, such as potato, wheat, strawberry, and sugarcane.

Genotyping has been a daunting task for genetic studies of polyploid crops, which lags far behind the diploid crop species.

Single nucleotide polymorphism (SNP) array is considered to be one of, high-throughput, relatively cost-efficient and automated genotyping approaches.

However, there are significant challenges for SNP identification in complex, polyploid genomes, which has seriously slowed SNP discovery and array development in polyploid species.

Ploidy is a significant factor impacting SNP qualities and validation rates of SNP markers in SNP arrays, which has been proven to be a very important tool for genetic studies and molecular breeding.

This review presents a complete overview of SNP array development and applications in polypoid crops, which will benefit the research in molecular breeding and genetics of crops with complex genomes.

According to the food chain below, which of these organisms most likely contains the least concentration of toxins (DDT) ?

agasfer [191]

Answer:

Hawk

Explanation:

Dichlorodiphenyltrichloroethan which is also known as DDT is a colorless, tasteless and almost odorless crystalline chemical compound. It was originally developed as an insecticide and it causes harm to wildlife animals.

When the chemical are sprayed or gets in contact with the soil it is the terrestrial organisms such as plants and primary consumers who gets affected the most due to direct contact with the chemical.

Animals such as hawks who are arboreal and tertiary consumers from the list of options don’t get affected directly from the source of the DDT contamination which makes them least affected.

Mrac [35]

Answer;

The mismatched pair is;

C) receptor proteins — bind with enzymes

Explanation;

- A receptor protein is a protein molecule that receives chemical signals from outside a cell. When such chemical signals bind to a receptor, they cause some form of cellular/tissue response, e.g. a change in the electrical activity of a cell.

-They are generally trans-membrane proteins, which bind to signaling molecules outside the cell and subsequently transmit the signal through a sequence of molecular switches to internal signaling pathways. There are two types of receptors: internal receptors and cell-surface receptors.

Jamal drew a flow chart to show how the carbon in his brain tissue originated as co2 in the atmosphere. interpret his model.

bezimeni [28]

We have heard about Respiration. In human beings, respiration is a cellular activity which takes place in the presence of oxygen and in result produces carbon dioxide. Jamal model is a clear manifestation of that process. Medulla is the region of a brain that controls the respiration activity. When we breathe we take in oxygen and the excess amount of carbon dioxide is removed from out body.

Brains cells have capability to detect the carbon concentration in blood and add excess amount of carbon from body to the air.
