Answer:
I think it's Helicase but im not quite sure
Explanation:
Answer:
Single strand binding proteins
Explanation:
Small single-strand binding proteins called SSB bind temporarily to each strand and keep the two strands separated. This step is important because DNA has a tendency to work itself back into a double helix shape.
hi i need your help guys! Using the periodic table, fill in the following table with the number of electrons in each energy level of the element given.
n = 1 level n = 2 level n = 3 level n = 4 level
Element (maximum 2) (maximum 8) (maximum 18) -----------
Carbon- ________ ________ ________ _______
i think its
carbon- 2 (there are two in the n=1 level) 4 (there are four in the n=2 level)
i might be wrong, but hope this helps :)
Electrons in atoms are arranged in energy levels. The electrons in the energy levels of carbon are;
n= 1 ------ 2 electrons
n = 2 ----- 4 electrons
n =3 ----- 0 electrons
n = 4 ----- 0 electrons
Carbon has the electronic configuration; 1s2 2s2 2p2.
This means that there are only two electrons in the n-1 level and there are four electrons in the n=2 level.
This makes a total of six electrons in carbon as shown.

Many eukaryotic cells can be grown in tissue culture in the laboratory. Suppose you have two tissue cultures, one in G1 phase and one in S
phase. How would you determine which culture was in G, and which was in S?
I could look for growth and synthesis of proteins and other macromolecules as well as increase in organelles, which would show a culture in G1. DNA being synthesized would show in cells in the S phase.
The best way to determine if the cell is the G or S phase is by looking at the state of the DNA molecule, and the presence of histones, centrioles, and spindle fibers.
What is the interphase?
The interphase occurs before cell division. It is composed of the G1, S, and G2 stages.
During the G1 stage, the cell duplicates in size. The organelles and other cytoplasmatic structures duplicate. The high intense biochemical activity is characteristic of this stage.During the S stage occurs the DNI replication process. At this point, also happens the synthesis of histones and other associated proteins. This is the only stage where the DNI molecule is replicated. The G2 stage is the final one before the cellular division. Here begins the slow process of DNI condensation. Duplication of centrioles completes. Structures such as spindle fibers are assembled.To determine which culture was in G stage, and which was in S stage, I would look at DNA molecule. The only stage in which DNA duplicates is during the S phase, so
If organelles are duplicated but not DNA, it is G1 stageIf organelles are duplicated as well as DNA, but the molecule is still lax, it is S phase. At this point there are also histones.If organelles are duplicated and DNA molecule began to condensate it is G2 phase. At this point there are also centrioles and spindle fibers.You can learn more about the interphase at

The picture shows a turgor pressure demonstration using stalks of celery in different salt solutions, so based upon the one with the most turgor pressure to the one with the least turgor pressure, T, Q, R, and S are in option A.
What is turgor pressure?Turgor pressure is the pressure exerted by water inside the plant cells against the cell wall. When the water flows into the cell due to osmosis, the cell becomes turgid, and the cell wall becomes stiff. In the given experiment, celery stalks are placed in different salt solutions, which affect the water potential of the cells. When the celery stalk is placed in a salt solution with a higher concentration of solutes than the cell sap, water molecules will move out of the plant cell by osmosis. This causes the plant cell to lose water and become flaccid.
Hence, based on the ones with the most turgor pressure to the ones with the least turgor pressure, T, Q, R, and S are in option A.

A. Genome, Chromosome, Gene, Nucleotide, Deoxyribose
Explanation:
According to this question, genetics as a branch of Biology is not exclusive of hierarchical basis. The following is an orderly sequence from LARGEST to SMALLEST in terms of molecular size:
Genome - Chromosome - Gene - Nucleotide - Deoxyribose
- The GENOME constitutes the whole genetic make up of an organism. This includes all the chromosomes contained in that organism.
- CHROMOSOME is the structure on which the inheritable unit called GENE is found.
- GENE is the molecular unit of inheritance which is made up of nucleotides.
- NUCLEOTIDES are monomers of nucleic acids made up of pentose sugar (dexyribose or ribose), nitrogenous base, phosphate group.
- DEOXYRIBOSE is a five carbon sugar that forms part of the structure of a nucleotide.

Muchas especies animales son territoriales al menos durante una parte del año. Eso significa que defienden un territorio más o menos amplio en el que no dejan entrar a otros individuos de su especie. A veces, el territorio es individual, otras es de una pareja y, en otros casos, corresponde a un grupo. Explica qué distribución origina cada uno de estos comportamientos.
Answer:
Por dependencia de otros organismos y competencia.
Explicación:
Estos diferentes tipos de comportamiento se deben a la dependencia de los organismos entre sí. Algunos organismos tienen la capacidad de vivir solos y cumplir con sus requisitos de vida por lo que no permiten que otros organismos ingresen a su espacio, algunos viven en parejas y algunos organismos viven en grupos o colonias porque no pueden sobrevivir solos en ese ambiente por lo que nosotros Se puede decir que algunos organismos dependen de otros organismos y algunos pueden sobrevivir solos.
The activation of complement is effective at initiating pathogen engulfment and destruction. This immune-protective process is made possible by:
Answer:
phagocytes that have receptors for the C3b component in order to engulf and destroy pathogens
Explanation:
The complement system refers to an immune mechanism by which plasma proteins are activated by pathogens and their binding to antibodies, triggering reactions on the pathogen surface that active components with effector functions. The complement system is an essential component of the innate immune response. Phagocytic cells have receptors for the C3b component in order to bind to C3b-coated cells/particles preparatory to phagocytosis. The C3b receptor is a glycoprotein that serves to regulate the complement system by inhibiting the activation of C3 and C5 convertases which cleave C3 and C5 and thus mediate complement effector functions.
