Review the numbered items below. Then, decide which of the following lists the correct steps of translation in the correct chronological order.
I. UGA codon is identified.
II. DNA is unwound to expose a single template strand.
III. tRNA molecules carrying various amino acids bond to mRNA based on the sequence of mRNA codons.
IV. mRNA arrives at the ribosome
V. Introns are snipped out of an mRNA molecule.
V. tRNA, carrying methionine amino acid, bind to mRNA.
Answer:
IV, VI, III, I
Explanation:
Translation is the process of synthesis of protein from with the help of messenger RNA (mRNA).
The process of translation include initiation, elongation and termination.
Initiation: In this step mRNA binds to ribososomes and tRNA, carrying start codon or methionine binds to mRNA.Elongation: In this step, the tRNA molecules carrying several amino acid bind to mRNA based on the sequence of mRNA codon and then moves (translocates) to the next mRNA codon which leads to amino acid chain.Termination: At the end, when a stop codon (UGA) identified, polypeptide is released.So, the correct chronological order is IV, VI, III, I.
Fine-tune reabsorption of calcium ions occurs in which of the following regions? Group of answer choices proximal tubule loop of Henle early distal tubule late distal tubule and collecting duct
Answer:
Proximal tubule
Explanation:
Calcium is an important element in the body with majority of its percentage located in the bones. Its ions perform different functions in the body which includes muscle contraction, hormones secretion and including all other functions.
Calcium ion is absorbed in the intestines and then reabsorbed in the kidney. Much percentage of calcium ions is reabsorbed by passive mechanisms in the proximal convoluted tubule of the kidney tubule as compared to all other parts of the kidney tubule.
Cellular respiration converts the reactants' oxygen and glucose into carbon dioxide, water, and energy. The reverse reaction of photosynthesis converts reactants of carbon dioxide and water into oxygen and glucose. These two reactions are part of which biogeochemical cycle?
Answer:
Photosynthesis and Cellular respiration take place in the carbon cycle
Explanation:
One of 4 biogeochemical cycles
carbon cycle
Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants need to get rid of carbon dioxide gas through a process called respiration.
Photosynthesis removes carbon dioxide from the atmosphere, while cellular respiration releases it into the environment. Cellular respiration and photosynthesis are significant carbon cycle processes. The carbon cycle refers to the procedures used to recycle carbon in the biosphere.
What cellular respiration in biogeochemical cycle?The exchange of carbon between the biosphere, geosphere, hydrosphere, atmosphere, and pedosphere occurs in one of the biogeochemical cycles. Photosynthesis occurs when carbon dioxide and sunshine are combined in green plants.
Therefore, living beings release carbon into the atmosphere. You emit carbon dioxide (CO2) into the atmosphere with each exhalation. Through a process known as respiration, organisms such as animals and plants must expel carbon dioxide gas.

Which of these conclusions is most likely correct about the two pairs of atoms?
Answer:
D. Carbon and oxygen form covalent bonds but sodium and chlorine form ionic bonds
Explanation:
Chemical bonds form between the atoms of elements. The types of chemical bondings that form are: covalent bond, ionic bond and more. Covalent bonds are bonds formed when atoms share valence electrons rather than transfer it. The shared bonding is in such a way that the outermost shell of both atoms are filled. This is the case of carbon and oxygen atoms in the diagram.
On the other hand, ionic bonding involves the transfer of electrons from one atom to another in order to form electrically charged ions that are bound to one another. This is the case of sodium atom, which has one valence electron in its outermost shell and transfers it to chlorine atom, which has seven electrons in its outermost shell. The sodium atom becomes a positively charged ion (+1) while the chlorine atom becomes negatively charged (-1).

Some individuals can be heterozygous for a particular mutation.This means that one of their chromosomes is normal and the other is mutated in some way. Approximately ___ of the gametes produced by an individual heterozygous for a deletion will be non viable.
Answer:
1/2 (50%)
Explanation:
During meiosis, homologous pairs of chromosomes are separated in order to form haploid cells, and this separation or assortment is known to be a random process. In consequence, the chromosome carrying the mutation will have a 1/2 (50%) chance of being inherited in the gamete that, after fertilization, produces a non-viable organism. In consequence, the non-mutated chromosome also will have a 1/2 chance of occurring in the offspring
The countercurrent multiplier is a system by which the:______.
a. nephron loop multiplies the concentration of salts in the interstitial fluid of the kidney medulla.
b. nephron loop dilutes the concentration of solutes in the tubular fluid at its hairpin turn.
c. vasa recta secretes multiple amounts of metabolic wastes against their concentration gradient.
d. vasa recta becomes more concentrated with nitrogenous wastes than the urine.
Answer: Option A.
nephron loop multiplies the concentration of salts in the interstitial fluid of the kidney medulla.
Explanation:
countercurrent multiplier is a system that utilize energy that create osmotic gradients and enable reabsorption of water thereby increase concentration of urine. The countercurrent multiplier uses electrolyte pumps there by making the nephron loop increase the concentration of salts in the interstitial fluid of the kidney medulla because it allows the nephron to reabsorb alot of water and and increase the concentration of urine for excretion while at the same time using as little energy as possible.
During meiosis, independent assortment determines which chromosomes a gamete inherits, while ____________ determines, within a chromosome, which material will come from the maternal and paternal version.
Answer:
Crossing over or recombination
Explanation:
Crossing over or genetic recombination is a stage in the late prophase of meiosis I where homologs lie close to each other in pairs to exchange chromosomal material creating new combination of genes as each homologs is derived from either the father or the mother.
This exchange determines the material to be inherited by the offspring producing genetic variation which males the offspring typically different from the parents (genetic variation).

Explanation:
Sexual orientation can be defined as the attraction that experiments an individual self-identified with a particular gender (either male or female) to other persons according to their sex, this orientation may be classified into three categories: heterosexual (attraction for people of opposite sex), homosexual (same-sex) and bisexual (either sex). In the last years, the mechanisms involved in sexual orientation have been subject to intense research. In this regard, the main part of the scientific community agrees that sexual orientation is the result of the complex interaction between genetic and environmental factors. This hypothesis is supported by the fact that genes whose expression is associated with particular human behaviors, including sexual orientation, have been recently identified and mapped. Moreover, it has been shown that environmental factors such as, for example, hormone exposure before birth (i.e., during fetal programming) may also determine sexual orientation.

After about two minutes of exercise, muscles require oxygen to continuously produce energy. Carbon dioxide is a byproduct of energy production and must be removed from the muscles to maintain homeostasis.
Answer:
When exhaling and inhaling, respiratory homeostasis occurs, exchanging gases at the level of the pulmonary alveolus.
This process is in charge of removing carbon dioxide from the muscles and their subsequent oxygenation.
Explanation:
Hemoglobin is in charge of associating carbon dioxide and delivering oxygen to the muscle that suffered physical activity.
Excess carbon dioxide is pathological, causing muscle acidosis in the muscle and even its possible denaturation since it is highly contained by proteins.
