Answer:
The oligosaccharide is assembled on the lipid carrier at the membrane of the ER
Explanation:
N-linked glycosylation consists of the attachment of an oligosaccharide (glycan) to a nitrogen atom of the asparagine (Asn) residue in the protein. N-linked glycosylation is a key posttranslational modification (PTM) capable of controlling protein structure and function, this pathway takes place in the plasma membrane in archaea organisms and in the membranes of the endoplasmic reticulum (ER) in eukaryotic organisms. In eukaryotic cells, the N-linked glycosylation conserved pathway consists of two steps. In the first place, the oligosaccharides are assembled on a lipid carrier called dolichyl pyrophosphate localized in the endoplasmic reticulum (ER). The dolichyl-phosphatase is a hydrolase enzyme that acts on phosphoric monoester bonds. Second, the oligosaccharides are modified by specific glycosyltransferases that transfer these molecules to selected Asparagine (Asn) acceptor residues of polypeptide chains that have entered the lumen of the ER. These N-glycans are firstly assembled as a dolichol-linked precursor oligosaccharide at the cytoplasmic face of the ER.
10. What changes during a chemical reaction between two compounds?
A. number of atoms
B. chemical bonds
C. total mass
D. total energy
Answer:
I think it's chemical bonds I'm not of that helped
The changes occurs in chemical bond during a chemical reaction between two compounds. The correct option is B.
What is chemical bond?A chemical bond is a long-lasting point of attraction among atoms, ions, or molecules which then allows chemical compounds to form.
Ionic bonds are formed by the electrostatic force between oppositely charged ions, whereas covalent bonds are formed by the sharing of electrons.
A covalent bond is the strongest bond in chemistry. In such bonding, each atom shares electrons that bind them together.
The bonds that hold molecules together break apart and form new bonds during chemical reactions, rearranging atoms into different substances.
Each bond requires a different amount of energy to break or form; without this energy, the reaction cannot occur, and the reactants remain unchanged.
Thus, the correct option is B.

When testing plant growth
Answer:
When working with the human body , I had the test so..
Explanation:
Uncontrolled: If an extraneous variable is not controlled for (held constant) its effects become confused with or confounded with the effects of the independent variable. It then has an unwanted effect on the dependent variable and is termed a confounding variable .The researcher can no longer draw conclusions regarding the causal
Carbon is getting stuck in reservoirs (atmosphere and ocean) which is leading to climate
change. Which of the following is not a reason for this issue?
O Decrease in plants means more carbon in the atmosphere
Increase in plants means more carbon in the atmosphere
O Less organisms in the oceans prolongs decomposition trapping carbon in the ocean
O Increased use of factories and burining of fossil fuels increases amount of carbon in the
atmosphere
Answer:
Increase in plants means more carbon in the atmosphere
Explanation:
The second option is not a reason for the issue. This is because plants remove carbon from the atmosphere for their life processes.
During the process of photosynthesis, green plants manufacture their food in the presence of sunlight using water and carbon dioxide.
Plants do not trap carbon. They ensure the movement of carbon in nature. Other choices shows how carbon get trapped in the atmosphere and ocean.A series of two point crosses is carried out between genes for brown eyes (bw), and arc wings (a), vestigial wings (vg) , ebony body color (e), and curved wings (cv).

Grapes growing on a vine are observed to shrink slightly during the day and increase in size at night. This is because:
a. developing fruits, such as grapes, transpire a lot of water to stay cool.
b. photosynthesis to produce sugar occurs in the light, but respiration and, therefore, the growth of new cells occurs mostly in the dark.
c. in leaves, phloem flow to growing sinks only occurs when the stomata are closed, because the transport capacity of the xylem is too small to supply water for both transpiration and phloem flow.
d. during the day, transpiration pulls on the water in the whole plant, causing the grapes to shrink slightly.
Answer:
b. photosynthesis to produce sugar occurs in the light, but respiration and, therefore, the growth of new cells occurs mostly in the dark.
Explanation:
Photosynthesis is the means by which green plants produce their foods by the use of sunlight, chlorophyll and carbon dioxide.
During the day, the grape make use of the process, photosynthesis, to get its sufficient food, thus the reason for the slight shrink. But at night, it respire well and new cells are produced. So that its size increase a bit.

What is the protozoan and who is the first to observe one?
Answer:
Protozoa is an informal term for a group of single-celled eukaryotes, either free-living or parasitic, which feed on organic matter such as other microorganisms or organic tissues and debris. Anton van Leeuwenhoek was the first person to see protozoa, using microscopes he constructed with simple lenses. Between 1674 and 1716, he described, in addition to free-living protozoa, several parasitic species from animals, and Giardia lamblia from his own stools.

Which of the following bones are considered to be the MOST proximal?
metatarsals
clavicle
ulna
olecranon
Answer:
Of the group of bones mentioned, the most proximal is the clavicle, which is part of the shoulder girdle.
Explanation:
Proximal is a reference term used in anatomy to indicate the structures that are closest to the center of the body.
The bones mentioned -clavicle, olecranon, ulna and metatarsals- are related to the function of the limbs. The clavicle is the closest bone to them, located between the neck and the thorax, on each side of the midline of the body.
Regarding the other options, other bones are distal, as they move away from the center of the body. In order from less distal to more distal they are found:
Olecranon, which is a bone eminence of the ulna, in the upper limb. Ulna or cubitus, which is part of the bones of the forearm. Metatarsals are the bones that form part of the foot.What part of the cell determines the type and order of the amino acids that make up a protein?
Answer:
The gene, or sequence of DNA, ultimately determines the unique sequence of amino acids in each peptide chain. A change in nucleotide sequence of the gene's coding region may lead to a different amino acid being added to the growing polypeptide chain, causing a change in protein structure and therefore function.

You remove pus from a wound and try to identify the pathogen multiple ways. The multi-locus gene tree showed your organism was most closely related to Streptococcus pyogenes but the 16S tree said it was most closely related to Streptococcus pneumoniae. Describe why this might be the case and other ways you should try to identify this organism.
Answer:
It occurs because phylogenetic analyses based on the 16S rRNA gene sequences may have insufficient resolution for distinguishing between closely related species
Another genomic method for streptococcal identification is whole-genome analysis (WGS)
Explanation:
The phylogenetic analysis of the highly conserved 16S rRNA gene sequences has recently been used to distinguish between prokaryotic species. However, this gene sometimes may show low resolution to distinguish between closely related species, and it has been suggested potential horizontal transference of rRNA genes. Moreover, multi-locus sequence analysis (MLSA) has also been used to identify species. MLSA analysis consists of analyzing simultaneously different genes and this technique has shown to have a high capacity for establishing relationships between species within a genus or genera within a family. Finally, whole-genome analysis (WGS) is the most powerful tool for distinguishing between closely species. WGS is a technique that provides a very high resolution which is based on the analysis of large-scale genome sequencing data generated by next sequencing generation (NGS) technologies.

In humans, the dominant allele N causes an abnormal shape of the patella in the knee, whereas n is the recessive normal allele. A separate gene is concerned with finger length, and the dominant allele B causes abnormally short fingers, whereas b is the recessive normal allele. A study focused on people who have both abnormal patellae and short fingers. These individuals were N/n . B/b in genotype, having inherited the N allele from one parent and the B allele from the other parent. These N/n . B/b people mated with normal spouses, producing 40 progeny classified as follows: Normal 3 Abnormal knees and short fingers 2 Abnormal knees only 17 Short fingers only 18
