what is a phosphorelated nucleoside?
Answer:
Nucleosides can be phosphorylated by a displacement reaction between phosphate and an electrophilic carbon of a nucleoside. To render a carbon electrophilic, the hydroxyl group must be converted into a leaving group of some kind (e.g., a halogen or sulfonate ester)
Explanation:
Why shoud temperature and oxygen be measured in a fish salinity tolerance experiment?
First, the solubility of oxygen decreases as temperature increases ¹. This means that warmer surface water requires less dissolved oxygen to reach 100% air saturation than does deeper, cooler water.
The star in the diagram represents which of these? A. origin of replication B. replication fork C. replication bubble D. Okazaki fragment
Given what we know about the process of DNA replication, we can confirm that the star shown in the diagram represents the replication fork.
During the replication of DNA in the cellular process of multiplication, a structure known as the replication fork is formed. This fork is a structure that forms by helicases, which tear the hydrogen bonds that hold together two DNA strands in the form of a double helix.
The resulting structure contains two prongs, which are branches of the original DNA strand which are no longer doble or in the form of a helix. This area where the strands are separating into prongs is the replication fork which is being marked in the diagram by the star.

There are five questions which are related to the Drilling down into petroleum's impact on life on Earth.
1. C. Iran produces more oil than the United States.
RPR is referred to as the Reserve to Production Ratio which is measured in years. Higher RPR of Iran demonstrates that it has more extraction rate than United States.
2. B. Human learned how to extract and burn fuel.
The major shift in Carbon cycle is because fossils and fuels have been excessively used extracted and burned for fuel and energy.
4. A. Trees of the Amazon remove Carbon dioxide from the air.
Forests are essential because they help remove carbon dioxide from air. The existing forests of Amazon are absorbing carbon dioxide which results in moderate climate and reduced climate change.

In the bacterial CRISPR system, the crRNA performs which of the following functions?
The CRISPR-Cas system is a genome engineering tool to edit the genome of any species. The crRNA is a sequence complementary to the target DNA of this genome editing system.
The CRISPR-Cas genome editing system is a recently developed genome engineering tool, which can be used to edit the genome of virtually any species.
This genome editing system consists of a nuclease (Cas) protein that cuts the DNA at the targeted regions, and a single guide RNA (sgRNA), which contains a crRNA (17-20 nt) sequence complementary to the target DNA.
In consequence, the sgRNA guides to the Cas protein in order to cleave the genome at targeted nucleotide sequences.

1) The biological levels of organization range from a single cell all the way up to the biosphere in a highly structured hierarchy. The biological hierarchy includes cells, tissues, organs, organ
systems, and organisms. Muscle is a type of tissue meaning it is made of groups of cells working together. However, the three types of muscle tissue are specialized for different functions.
What do all three types of muscle tissue have common? Select ALL that apply
A) Muscle cells all contract.
B) Muscle cells are all striated
Muscle cells all cause movement
D) Muscle cells are all cylindrical
E) Muscle cells all have one nuclei.
Answer:
A C D
Explanation:
Got it right
All three types of muscle tissue have three things in common: Muscle cells all contract; muscle cells all cause movement, muscle cells are all cylindrical; that is, they have the same similarities as options A, C, and D.
What are muscle cells?All three types of muscle tissue—skeletal muscle, smooth muscle, and cardiac muscle tissues have some common features, such as being composed of elongated cells and having the ability to contract and generate force that enables muscle tissue to cause movement, such as the movement of a limb, the beating of the heart, etc. Skeletal and cardiac muscle cells are striated, meaning they have alternating bands of dark and light regions, while smooth muscle cells are not.
As a result, muscle cells all contract; muscle cells all cause movement; and muscle cells all have cylindrical shapes, i.e., options A, C, and D.

IF a man with blood type A, one one of whose parents had blood type O, marries a woman with blood type AB, what are the putative genotypes of the offspring?
Answer:
The 1st child will surely have AA,The 2nd might have AB/OB and the last one will surely have OB
Explanation:
I studied at school like 2 yrs ago
I am sure
Answer:
If the man has blood type A one of whose parents had blood type O then he must be having the genotype IAi and the woman with blood group AB would have genotype IAIB. So if they produce offspring than the putative genotype of the offspring would be IAIA, IAi, IAIB, and IBi.
Explanation:
IA i
IA IAIA IAi
IB IAIB IBi
Therefore out of four offspring, two offspring would be having A blood group, one offspring would have AB blood group and one offspring would have B blood group.
