Long wall method is the least likely to cause a loss of biodiversity. Hence the correct option is A.
The long wall method of mining involves the extraction of coal or minerals from a long wall of rock. This method minimizes the surface disturbance and does not require the removal of large areas of overlying vegetation or habitat. The long wall method has a lower impact on biodiversity because it disturbs a smaller surface area and has a more limited footprint.
Mountaintop removal mining involves the removal of the summit or ridge of a mountain to access coal or minerals. This process can result in the destruction of large areas of forest and habitat, leading to significant loss of biodiversity, including the displacement and endangerment of plant and animal species native to the region.
Hence the correct option is A.

thinking about the components in pcr, do you think there are major differences in the process of dna replication between species?
The major difference in the process of DNA replication between species is the linear order of nucleotides, which can be amplified by PCR. This technique enables the amplification of specific DNA fragments.
The Polymerase chain reaction (PCR) is a technique widely used in molecular biology in order to amplify and thus identify small DNA fragments (approx. 1000 pb).
The PCR uses all materials required to carry out DNA replication: a thermostable DNA polymerase, primers (DNA oligonucleotides), deoxyribonucleotides (ddA, ddG, ddC, or ddT), and template DNA.
The template DNA indicates the linear order of nucleotides that will be added to the amplified DNA fragment, which is highly specific and may vary even between individuals of the same species.

Answer:
Heterogeneous Distribution, ModularityHeterogeneity in statistics means that your populations, samples or results are different. It is the opposite of homogeneity, which means that the population/data/results are the same. ... For example, if everyone in your group varied between 4'3″ and 7'6″ tall, they would be heterogeneous for height.Explanation:

There are 22 amino acids used within the human body. How can these 22 molecules be used to make hundreds of thousands of different proteins?
Answer:
Because amino acids can be arranged in many different combinations, it's possible for your body to make thousands of different kinds of proteins from just the same 21 amino acids. You may see books that say there are only 20 amino acids.

In case of multiple alleles, the same DNA strand is involved, whereas polygenic inheritance is found on multiple DNA strands. Multiple alleles involve multiple alternate forms of a gene, while polygenic traits are regulated by a group of non-allelic genes. ... Hence, in blood type, there is one gene but three alleles
Based on the video, do you think changes to the environment could still affect living things on Earth today? Explain your answer using information from the video to support your argument.

how does a single genome code for so many types of tissues
Answer:
The genome of a cell contains in its DNA sequence the information to make many thousands of different protein and RNA molecules. A cell typically expresses only a fraction of its genes, and the different types of cells in multicellular organisms arise because different sets of genes are expressed.
The genome, which is the second layer, regulates gene access, allowing each cell type to activate its own unique genes while shutting off the majority of the others.
What is genome?The complete set of DNA instructions present in a cell is known as the genome. The human genome is made up of 23 pairs of chromosomes that are found in the cell's nucleus and one tiny chromosome that is found in the mitochondria.
Everything a person needs to grow and operate is encoded in their genome. The DNA sequence in a cell's genome contains the instructions needed to create tens of thousands of different protein and RNA molecules.
Thus, in multicellular organisms, distinct cell types develop because diverse sets of genes are expressed, even though a cell normally expresses just a portion of its genes.

!!!!!How do radioactive elements help scientists establish how old rocks and fossils are?!!!!
Answer:
I will give a hypothesis. Just like a tree, when you cut a tree by its trunk, you will the rings. The rings around it represents the tree's age. So when you cut rock, the pores in the rock determine whether it is an old rock or a fossil rock.
Explanation:
The reason is, if it is limestone and it is an old rock, the pores will be slightly big and if the limestone is a fossil rock, then the pores will be bigger due to leaching or denaturing of the minerals in the rock through the ages.
Answer:
Radioactive elements all have a specific half-life, which is the time it takes for half of the radioactive elements in the fossil to disappear. In absolute dating, numbers are given to the ages of different fossils and rocks. To give an exact number or age range to a fossil, scientists use radiometric dating. This is where the half-lives of radioactive isotopes within the fossil or in the rock surrounding it are analyzed. Radioactive isotopes decay at a steady rate. By measuring the ratio of the radioactive isotope to the stable isotope it decays into, the number of completed half-lives can be estimated. Since you know the rate of decay, you can estimate dates with this ratio.
Explanation:
This is the process used to help scientists establish how old rocks and fossils are

the transport a very large molecules such as proteins
Answer:
Very large molecules such as proteins are too big to move through the cell membrane which is said to be impermeable to them. The type of transport proteins present in a cell membrane determines which substances the membrane is permeable to. CO2 molecules pass directly through phospholipids. Glucose molecules travel through the proteins.
