nordsb [41]
The reason why nost scientists thought  that the first true cells formed on Earth were anaerobic is being shown in the second option :B. because there was no oxygen on early Earth. Paying attention to this fact scientists discovered that first cells were prokaryotes and greatest part of them created oxygen as a toxic by-product of their own metabolism which make them understand how the planet was provided with oxygen and made a conclusion that first cells were anaerobic.

An organism is described as 2n = 48.A) How many chromatids per chromosome are in one meiotic cell during prophase 2?B) How many
Alex

Answer:

A) 48

B) 96

C) 48

D) 48

Explanation:

Attached is a table summarizing the number of chromosomes and chromatids in the different stages of mitosis and meiosis in humans who are described as 2n = 46.

For the organism which is described as 2n = 48, substitute 46 in the table for 48 to get the appropriate figures.

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.

When the knee is bent, the hamstring group of muscles contract. What is the insertion of this muscle group?
DIA [1.3K]

Answer:

The Knee Flexor Muscles

Explanation: The Hamstrings All three hamstring muscles originate from the ischial tuberosity and run toward the knee. The biceps femoris muscle is inserted into the head of the fibula. It can rotate the lower leg so that the foot points laterally.

Why do the prevailing winds blow from west to east in the Northern Hemisphere?
Bezzdna [24]

Answer:

Low pressure spins counterclockwise, causing weather systems to move from west to east in the Northern Hemisphere.

This is due to lower air pressure further North America than in the tropics. Since low-pressure systems spin counterclockwise, winds move from the west to the east.

Prevailing weather results from expansive convection currents formed by the temperature differences on the surface of the earth as latitude increases. The Coriolis effect adds the twist.

I got this from a few sites so use this information as you want and be careful <3
