Answer:
Cell cycle consists of interphase and mitosis. During interphase there are 3 phases- G1, S and G2 phases. G1 is the resting phase after previous mitotic phase, S phase is DNA synthesis phase and G2 phase is again resting phase.
DNA synthesis occurs before mitotic phase which is the actual cell division phase and chromosomes are condensed during mitotic phase therefore it's in the chromatin form that DNA is synthesised.

Explanation:
A scientist wishes to create bacterial colonies on an agar plate for observation of growth. Unfortunately, directly adding bacteria from the original culture results in too many bacterial colonies to count. In order to create a solution of proper bacterial concentration for observation, the scientist performs a three-step 1:100 serial dilution of the original bacterial culture. What is the dilution factor of the final solution
Answer:
10⁶
Explanation:
A 1:100 serial dilution is a dilution in which the concentration decreases 100 fold (i.e., in each dilution the concentration of the culture must be multiplied by 10⁻²). The question above indicates that a three-step 1:100 dilution was applied, which means >> 10⁻² x 10⁻² x 10⁻² = 10⁻⁶. Moreover, the dilution factor can be calculated by dividing the volume of the diluted solution by the volume of the concentrated solution. The dilution factor is the inverse of dilution, thereby in this case this value is equal to 10⁶ (dilution = 10⁻⁶ >> dilution factor = 10⁶).
Todos los miembros de dicha familia tienen simpatía por las mismas ideas políticas
Answer:
¿todos los miembros de dicha familia tienen simpatia por las mismas ideas políticas? En las últimas elecciones presidenciales, ¿todos los miembros de dicha familia votaron por el mismo partido?¿Puedes preguntarles cómo votaban los integrantes de esa familia hace veinte años, y hace cincuenta años? ¿Qué ha cambiado? Escribe en tu cuaderno tus averiguaciones
Explanation:
Mi familia tiene diferentes ideales políticos y por eso votaron por diferentes partidos, antes el proceso era manual
En las elecciones actuales les he preguntado a los miembros de mi familia y no todos votaron por el mismo partido político unos creen en uno de los partidos políticos y otros creen en otros. Por lo tanto no todos simpatizan con las mismas ideas políticas
Anteriormente se votaba por medio de un papel escrito, entonces el proceso es mucho más lento y menos automatizado que con maquinas
No, cada familiar tiene una idea política distinta.
-no votaron por el mismo partido político pues siempre algunos presidentes hacen promesas y no las cumplen.
-las votaciones siempre las han realizado por numero de DUI, en institutos o en las calles frente a las alcaldías, tenían que buscar el numero de urna en la cual estaban asignados.
-el cambio a sido la tecnología y el voto residencial, pues con la tecnología se ha hecho mas fácil el cuento de los votos y el voto residencial a permitido que se les facilite asistir al centro de votación.

If a tRNA molecule has an anticodon which reads AGGCCG, what was the codon on the mRNA molecule?
TCCGGA
UCCGGC
UCCGGU
CTTAAG
The codon is the sequence of nucleotides that carry genetic information that determines which amino acid should be added to the building protein. Nucleotides in this sequence pair with nucleotides from the tRNA anticodon. In the exposed example, the correct codon pairing the given anticodon is is UCCGGC.
Before expplanation, let us review some theoretical frame to answer the question.
During protein synthesis, the ribosome reads mRNA in the 5´ to 3´ direction, while tRNA adds the correct amino acids to build the polypeptide, according to the codons readen in the mRNA chain. A codon is a short sequence of three nucleotides that store the genetic information for the aminoacids´ assembly. Each of the codons represents one of the 20 amino acids used to build the protein. Each tRNA has two important sites. One of them that couples with the codon of the mRNA molecule, named anticodon. The other site couples with an amino acid. tRNA allows amino acids to align according to the nucleotidic sequence in the mRNA molecule.
Once the new amino acid joins the growing protein, the binding between the amino acid and the tRNA breaks, releasing the molecule, which is now available to join another amino acid and repeat the cycle.
• Anticodon: Sequence of bases that pairs with the mRNA codon.
• Amino Acid: the amino acid that is codified by the mRNA codon.
Remeber that:
Adenine forms pairs with Uracyl ⇒ A↔UGuanine pairs with Cytosine ⇒ C↔GIn the exposed example, the tRNA anticodon is AGGCCG, so we need to find its complement.
We know that Adenine pairs Uracyl, Guanine pairs Cytosine, and Cytosine pairs Guanine. So,
Anticodon → AGGCCG
Codon → UCCGGC

describe the role of enzymes in seeds germination
Answer:
Enzymes such as amylase ,protease and lipase are liable for solubilizing spare food materials in form of starch, protein and lipids correspondingly
in seed and deliver energy and other fundamentals food materials to germinating embryo.
The seed proteins are catalyzed by protease enzyme and break it into amino acid and peptides that a e transferred to growing embryo.
The amino acids obtained from metabolism of the proteins are further used in biosynthesis of enzymes,hormones,proteins, pyrimidines and Purine bases.
The starch is catalyzed by enzyme amylase that provides the food materials for growth and development of embryo . Similarly lipase are enzymes that are responsible for metabolism of the triacylglycerols into glycerols and fatty acids.This is also the source of energy for growing embryo
The compound 2,4-dinitrophenol (DNP) is a lipid soluble compound that has been used as a weight loss agent. It functions this way by causing the inner mitochondrial membrane to become leaky with respect to protons. Which result might be expected if cells treated with DNP were examined in detail
Answer:
ATP production would be slower in these cells than in untreated cells
Explanation:
Oxidative phosphorylation is the third stage of cellular respiration, which occurs in the mitochondria of animal and plant cells. Oxidative phosphorylation represents the most efficient pathway to generate energy in animal cells by the production of Adenosine triphosphate (ATP) as a consequence of the transfer of electrons from nicotinamide adenine dinucleotide (reduced form) (NADH) or flavin adenine dinucleotide (reduced form) (FADH2) to molecular oxygen (O2) through a sequential series of electron carriers. The 2,4-Dinitrophenol (DNP) poison is an uncoupler of oxidative phosphorylation that carries protons across the mitochondrial membrane, thereby leading to a rapid consumption of energy without the production of ATP. This mitochondrial uncoupler (DNP) has been used as a dieting drug during the 30's decade (1930), but was rapidly banned due to its side effects, which include, among others, tachycardia, hyperthermia, tachypnea, and metabolic acidosis.
Single Strand Binding Proteins are responsible for:
A. keeping the strands separated during replication.
B. unwinding and separating the DNA strands.
C. adding the new bases.
D. linking the short sections of the lagging side.
Reset Selection
Answer:
A. keeping the strands separated during replication
Explanation:
Prior to the process of DNA replication, the double-stranded DNA must first be separated into single strands by an enzyme called DNA helicase. This is done so that each DNA strand can serve as template for the synthesis of another.
After the unwinding and separation, the single strands still need to be kept apart during the synthesis of new nucleotides by DNA polymerase. This role of keeping the strands separated during replication is carried out by SINGLE STRAND BINDING PROTEINS.

Answer:
negative impact
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. These negative impacts can affect human behavior and can prompt mass migrations or battles over clean water.
positive impact
Environmental regulations have greatly improved air and water quality, especially in areas that were dirtiest before regulation. Reducing airborne particulates is especially beneficial, saving thousands of lives and preventing millions of illnesses each year.

Explanation:
The muscle weakness of myasthenia gravis results from loss of acetylcholine receptors in the end-plate membrane. the motor neuron action potential being too small to shock the muscle fibers. insufficient acetylcholine release from presynaptic vesicles. excessive acetylcholinesterase that destroys the neurotransmitter. All of the answers probably contribute to the muscle weakness.
Answer:
The correct answer is ''loss of acetylcholine receptors in the end-plate membrane.''
Explanation:
Myasthenia gravis represents a human autoimmune disease. The neuromuscular junction abnormalities that occur in this disease are due to antibody-mediated processes. A reduction in the number of functional acetylcholine receptors on the postsynaptic membrane was established to contribute to the physiological abnormalities of myasthenia gravis. The reduction in receptors is due to immunological alterations directed against the acetylcholine receptor. Normally, when acetylcholine binds to its receptor, it opens allowing the rapid entry of cations, especially sodium. With this, the depolarization of the postsynaptic region of the muscle fiber occurs. Although acetylcholine is normally released in myasthenia gravis, it is not capable of causing an action potential in the muscle sufficient to initiate or weaken contraction. In patients with myasthenia gravis, failure to activate muscles is responsible for myasthenic fatigue. Most patients have elevated serum titers of antireceptor antibodies, which in turn accelerate receptor degradation.
