During translation, tRNA adds the correct amino acid to the growing protein, following the mRNA codon sequence. Tryptophan, Lysine, Leucine, Tyrosine.

Translation is the stage in protein synthesis that follows transcription, and occurs in the cytoplasm.

When mRNA leaves the nucleus and moves to the cytoplasm, it meets a free ribosome that is the primary structure for protein synthesis. Ribosomes are composed of two subunits of rRNA associated with different tRNA that carries amino acids.

The ribosome reads mRNA in the 5' to 3' direction, and, according to the codons that are being readen in mRNA, tRNA transfers the correct amino acids to build the polypeptide chain.

Let us remember that the codon is the sequence of three nucleotides present in mRNA. The molecule carriesa a start codon and stop codons.

Each tRNA has two important sites. One of them is the antidocon that couples with the codon of the mRNA molecule. The other site couples with the coded amino acid.

The protein is synthesized from the amino terminus to the carboxy terminus.

ACC               UGG                ACC             Tryptophan

The thin layer of cartilage on the ends of bones where they form joints is called the articular cartilage.

Articular cartilage is a smooth, elastic, and durable connective tissue that covers the ends of bones where they meet to form joints. This cartilage allows the bones to glide smoothly over one another, protecting them from friction and wear.

Articular cartilage is unique in that it has no blood supply. Instead, it receives nutrients and oxygen from the surrounding synovial fluid. This fluid is produced by the synovial membrane, which lines the joint cavity. The synovial fluid helps to nourish the articular cartilage and keep it lubricated, reducing friction and preventing damage. The smooth surface of the articular cartilage also helps to distribute weight evenly across the joint, reducing stress and preventing injury.

Articular cartilage is important for joint health and function. When it is damaged or degraded, it can lead to pain, stiffness, and loss of mobility. This can be caused by injury, disease, or normal wear and tear. Treatment for damaged articular cartilage may include rest, physical therapy, medication, or surgery. In some cases, damaged cartilage can be repaired or replaced using techniques such as microfracture, autologous chondrocyte implantation, or osteochondral grafting.

Explanation:

Given a bacteria culture starts with 2000 bacteria. a) It take 2.93 hours for the number of bacteria to double ; b) It will take  4.21 hours. for the bacteria population to grow to 90000.

a) After 6 hours the estimated count is 60 000. Round your answer to 2 decimal places of an hour. For calculating the time taken for a number of bacteria to double, we use the formula, t = (ln 2)/k where, t = time, k = doubling time (in hours), and ln = natural logarithm. Given that the initial number of bacteria is 2000 and the number of bacteria after 6 hours is 60 000. The estimated growth rate, k = (ln N₁  - ln N₀ )/(t₁  - t₀ ) where N₁ is the final number of bacteria, N₀ is the initial number of bacteria, t₁ is the final time, and t₀  is the initial time. So, we have k = (ln 60 000 - ln 2000)/(6 - 0) = 1.418 / 6 hours = 0.236. Therefore, t = (ln 2)/k = (ln 2)/0.236 = 2.93 hours (approximately) to double the number of bacteria. Hence, the answer is 2.93 hours.

b) Assume the doubling period was half an hour.  Round your answer to 2 decimal places of an hour. Given that the doubling period was half an hour. Therefore, the growth rate, k = 1/doubling time = 1/0.5 = 2 per hour. Let t be the number of hours to grow to 90,000 bacteria. Then, we have 90,000/2000 = 2^(t/0.5) => 45 = 2^(t/0.5) => ln 45 = (t/0.5) ln 2 => t = (ln 45)/(0.5 ln 2) = 4.21 hours (approximately). Therefore, the answer is 4.21 hours.

(a) Approximately 0.0401 or 4.01% of pregnancies last more than 269 days.

(b) Approximately 0.6247 or 62.47% of pregnancies last between 243 and 259 days.

(c) The probability is 0.1587 or 15.87%.

(d) Since this is less than 0.05, the probability of a "very preterm" baby is less than 0.05. Therefore, "very preterm" babies are considered unusual.

To solve these problems, we can use the standard normal distribution and z-scores.

(a) To find the proportion of pregnancies that last more than 269 days, we need to calculate the area under the normal curve to the right of 269. First, we calculate the z-score:

z = (269 - u) / o = (269 - 255) / 8 = 14 / 8 = 1.75

Looking up the z-score of 1.75 in the standard normal distribution table, we find that the corresponding area to the left is approximately 0.9599. Since we want the proportion to the right of 269, we subtract this value from 1:

Proportion = 1 - 0.9599 = 0.0401

Therefore, approximately 0.0401 or 4.01% of pregnancies last more than 269 days.

(b) To find the proportion of pregnancies that last between 243 and 259 days, we need to calculate the area under the normal curve between these two values. We calculate the z-scores for both values:

z1 = (243 - u) / o = (243 - 255) / 8 = -12 / 8 = -1.5

z2 = (259 - u) / o = (259 - 255) / 8 = 4 / 8 = 0.5

Using the standard normal distribution table, we find the area to the left of z1 (-1.5) is approximately 0.0668, and the area to the left of z2 (0.5) is approximately 0.6915. To find the area between these two z-scores, we subtract the smaller area from the larger area:

Proportion = 0.6915 - 0.0668 = 0.6247

Therefore, approximately 0.6247 or 62.47% of pregnancies last between 243 and 259 days.

(c) To find the probability that a randomly selected pregnancy lasts no more than 247 days, we calculate the z-score:

z = (247 - u) / o = (247 - 255) / 8 = -8 / 8 = -1

Looking up the z-score of -1 in the standard normal distribution table, we find the corresponding area to the left is approximately 0.1587. Therefore, the probability is 0.1587 or 15.87%.

(d) To determine if "very preterm" babies (gestation period less than 237 days) are unusual, we calculate the z-score:

z = (237 - u) / o = (237 - 255) / 8 = -18 / 8 = -2.25

Looking up the z-score of -2.25 in the standard normal distribution table, we find the corresponding area to the left is approximately 0.0122. Since this is less than 0.05, the probability of a "very preterm" baby is less than 0.05. Therefore, "very preterm" babies are considered unusual.

The cis to trans conversion of retinal when photopigments respond to light is called isomerization.

What is isomerization?Isomerization is a chemical process that converts one isomer into another without altering the overall atomic composition. Isomerization may be a physical process such as changing the position of a molecule within a crystal lattice or a chemical process in which the chemical structure of a molecule is rearranged. It is generally referred to as a chemical reaction involving a structural modification that occurs spontaneously or catalytically.

Isomerization is a natural process that occurs in a variety of biological systems, including retinal when photopigments react to light. When retinal absorbs light, the retinal molecule undergoes a cis-to-trans isomerization. The conformation of the molecule alters from a bent, unstable conformation to a straight, more rigid one, resulting in the activation of an ion channel in the cell membrane. This, in turn, results in the generation of a visual signal that is sent to the brain, and the sensation of light is perceived.

Answer:

A protostar looks like a star but its core is not yet hot enough for fusion to take place. The luminosity comes exclusively from the heating of the protostar as it contracts. Protostars are usually surrounded by dust, which blocks the light that they emit, so they are difficult to observe in the visible spectrum.

Explanation:

A protostar is not considered a star until it gets its energy from nuclear fusion instead of gravitational contraction. Gravitational contraction is the process of a cloud's gravity overcoming its internal pressure and causing a collapse.

A protostar is the stage in a star's life before it is hot enough to fuse hydrogen (13 million K). Fusion is the opposite idea to the atomic bombs dropped on Japan. Those bombs split atoms (specifically U-235?), where as in fusion, atoms are fused together. Protostars are simply out hot enough to fuse Hydrogen, and therefore are not main sequence stars like our sun.

Main sequence stars are stars that fuse hydrogen and exhibit a state of "Hydrostatic Equilibrium". Hydro-what? HE (as I'll call it) is where the fusion in a stars core counter acts the force of gravity attempting to compress the star.

Protostars do not exhibit this characteristic, rather they are in a state of collapse until they are compressed to a point where pressure is high enough to have a temperature high enough to fuse Hydrogen.

Protostars do fuse protons to Deuterium (a isotope of helium) but don't worry about this.

Protostars are technically stars, but I think you were asking how they defer from other stars.

These two plants look so similar if their common ancestor was very distant because it shows analogous evolution which is the evolutionary process in which organisms exhibit similarities in function but differ in the evolutionary origins.

The term analogous is derived from  Greek analogos, which means “according to a proper ratio or proportion".

Analogous evolution is the type of evolution having similarities in function but have different evolutionary origins. In analogous evolution, different species with different evolutionary lines use their biological structures for the same purpose. This type of evolution is called as convergent evolution.

The structure evolved independently in different individuals which serve the same function. Examples of Analogous evolution, Wings of Birds and insects.

Meg, because trees with needles are not deciduous.

Evergreens have thick, waxy leaves that are coiled up into long, thin needles. The needle form allows evergreens to save water in the summer and winter, allowing photosynthesis to continue. This is why the needle leaves may stay connected and green all year.

Because evergreen needles are thinner and have less surface area to dry or freeze than huge deciduous leaves, they can endure low weather. Their breathing pores, known as stomata, are located at the base of the needles and stay closed during the winter to protect them from temperature extremes.

Luminance response can be tested with an option(d) I or II i.e, near range photometer or telescope photometer.

The luminous intensity per unit area of light traveling in a specific direction is measured photometrically as luminance. It indicates how much light enters, exits, or is reflected from a specific area and falls within a specified solid angle.

The visual system's ability to function depends heavily on luminance and contrast. Vision is impossible without light (luminance = 0), and without contrast, we are unable to see spatial or temporal patterns. The first stage in seeing, which enables all other visual processes, is the capacity to respond to brightness.

A photometer is a tool used to gauge light's characteristics. A photometer can be used to measure a light source's brightness, color, and flux among other attributes. Photometers gather radiation released by the light source to determine the wavelengths of light and atomic emissions.
