Answer:
Other species that rely on those fish would die off. The extinction of one species can lead to the extinction of another and so on.
So u get a codon chart it'll look like a circle with a bunch of letters. Then you use the letters u are given for every dash such as UCU and you go biggest to smallest letter until you hit an amino acid or stop then what you write down is that amino acid you hit. For an example, we'll use UCU. You go to the big letter U inside that big U will be a smaller C and inside that C will be a smaller U which leads to an amino acid or a stop codon. And you do this with every group of 3 letters. If one is missing it stops prematurely and if there is an extra when it may have a mutation. I hope that helped! If not there are YouTube videos out there that can help.
The correct answer is
B. bases in DNA in the nucleus
Answer: The genotype ratio of offsprings of a cross between one homozygous tall plant and one heterozygous tall plant is 2TT:2Tt
The phenotype ratio is that all offsprings will be tall.
The genotype ratio of a cross between two heterozygous red flowers is 1RR:2Rr:2rr. The phenotype ratio is 3 Red flowers: 1 white flower.
Explanation: From the information given, tall is dominant and short is recessive while red is dominant and white is recessive.
Let T represent the allele for tall height, t represent the allele for short height, R represent allele for red flowers and r represent allele for white flowers.
The genotype of a homozygous tall plant is TT, the genotype of a heterozygous tall plant is Tt, the genotype of a heterozygous red flowered plant is Rr.
The possible genotypes of offsprings of a cross between one homozygous tall plant and one heterozygous tall plant are TT and Tt.
Tt will manifest outwardly as tall because T is dominant over t. Therefore, all the offsprings will be tall.
The possible genotypes of a cross between two heterozygous red flowers are RR, Rr and rr. RR will manifest as red, Rr will also manifest as red because R is dominant to r while rr will manifest as white because white allele (r) is recessive. Therefore 3 plants will be red-flowered while 1 plant will be white flowered.
See the attached punnet squares for details of the cross.
Answer:
Most of the world's coal mines come from China, India, the United States, the European Union, and Australia.
Explanation:
- <u>China: </u>In the year 2018, China alone produced approximately 3523 million tonnes of coal. Though China is the largest producer of coal in the world, it has to import coal from other countries to fulfill its energy needs. China's share in the total coal produced in the world in the last 12 years is 39.7%.
- <u>India:</u> The production of coal in India reached approximately 716 million tonnes in the year 2018. The total amount of coal produced in India in the last 12 years makes up 7.5% of the coal produced all over the world.
- <u>The United States: </u>The coal produced in the United States in the year 2018 was approximately 702 million tonnes. The last 12 year share of the coal produced in the US is 16.2% of the total coal produced all over the world.
- <u>The European Union:</u> The countries that constitute the European Union togetherly produced approximately 490 million tonnes of coal in the year 2018. The last 12-year contribution of the EU to the total coal produced in the world is 9.2%.
- <u>Australia:</u> The production of coal in Australia for the year 2018 was approximately 481 million tonnes. Australia alone produced 6.2% coal of the total world production of coal in the last 12 years.
