Answer: 298.9 million years old
Explanation: hope it helps luv ❤✨
A piece of coal would be 298.9 million years old. This is because the Permian period was initiated approximately 298.9 million years ago.
What are the characteristics of coal?The characteristics of coal are as follows:
It primarily consists of carbon, hydrogen, and oxygen.It contains a very less amount of sulfur and nitrogen.It is black in color and has a metallic luster.It is significantly hard as stone. Coal is widely utilized in power plants in order to generate electricity.According to ancient tomes and periods, the Permian period ends about 252.2 million years ago and it was the time of the initiation of the carboniferous period that further extends to the Triassic period. This was all about the time duration when the first piece of coal was found in the atmosphere.
Therefore, a piece of coal would be 298.9 million years old.

When exercising routinely, timing the food that you eat around your exercise activities is important. Carbohydrate intake is particularly influential, with different ideal timings for simple carbohydrates and complex carbohydrates. The best types of carbohydrates to eat during and/or immediately after exercise are simple carbohydrates, whereas complex carbohydrates are ideally consumed a couple of hours before exercise. Complex carbohydrates take longer to digest and enter the bloodstream and can help build glycogen stores.
Sort the following food items into their respective bins based on whether they are simple, complex, or noncarbohydrate-rich foods.
Drag the appropriate items into their respective bins

What items are used to identify the genetic makeup of an unknown organism?
Answer:
Polymerase chain reaction machine
Primers
Petri dishes
Test tubes
Pipettes
DNA Polymerase
Free nucleotides
The organism to be identified
Explanation:
To identify the genetic makeup of an unknown organism, the nucleotide sequences fond in the Deoxyribonucleotide (DNA) of a known organism is matched to the DNA of some known organisms. If there is a certain degree of sameness in most of the matched parts, then the unknown organism can be said to be related to the known organism. This is a comparative study.
To carry out this identification, items used include; primers, the PCR machine, test tubes, DNA polymerase, free nucleotides, etc.
DNA replication is said to be semiconservative. Which of the following statements correctly explains what this means?
Answer: DNA is a double stranded molecule. When DNA is copied the two strand of DNA (old strands) separate and new nucleotides match up with the two separated strands.
This process creates two identical double stranded DNA molecules are formed. Each DNA molecule contains one strand of the original DNA molecule and one newly synthesized (made) strand.

The semi-conservative nature of DNA replication illustrates that each strand in the DNA double helix function as a template for the synthesis of a new or complementary strand.
What is DNA replication?DNA replication may be defined as a type of biological process that deals with the synthesis of two identical replicas of DNA from one original DNA molecule during cell division.
The semi-conservative model of DNA was proposed by Watson and Crick. This model implies that each double helix of DNA is composed of one new and one old strand.
In semi-conservative replication, the parental double helix is half conserved and each parental single strand remains intact.
Therefore, DNA replication is said to be semi-conservative due to the process of each new double strand consisting of one parental strand and one new daughter strand.

Can genetic engineering cause harm to humans?
Answer:
There are many risks involved in genetic engineering. The release of genetically altered organisms in the environment can increase human suffering, decrease animal welfare, and lead to ecological disasters. The containment of biotechnological material in laboratories and industrial plants contributes to the risk of accidental release, especially if the handling and storage are inadequate.

Why does a floating leaf indicate that photosynthesis is occurring?
Answer and Explanation:
A floating leaf indicates that photosynthesis is occurring because it means the leaf is producing oxygen, a biproduct of photosynthesis. It is possible that photosynthesis is occurring in a leaf that is not floating because it's possible that the leaf is denser than the solution and can't float.

On the planet Kermit, in the Muppet population, there are two autosomal loci of interest. The first locus has alleles A and a, and the second locus has alleles B and b. A and B are the dominant alleles at the respective loci. The loci act in an epistatic manner, identical to the way two genes interact to produce coat color in labradors. The phenotype here is muppet hair color. We have the following results:
Muppet hair color as a function of two-locus genotypes
Two-locus genotype Muppet hair color
