Lyra Latin for lyre, from Greek is a small constellation. It is one of 48 listed by the 2nd century astronomer Ptolemy, and is one of the 88 constellations recognized by the International Astronomical Union. Lyra was often represented on star maps as a vulture or an eagle carrying a lyre, and hence sometimes referred to as Aquila Cadens or Vultur Cadens. Beginning at the north, Lyra is bordered by Draco, Hercules, Vulpecula, and Cygnus. Lyra is visible from the northern hemisphere from spring through autumn, and nearly overhead, in temperate latitudes, during the summer months. From the southern hemisphere, it is visible low in the northern sky during the winter months.

Vega, Lyra's brightest star is one of the brightest stars in the night sky, and forms a corner of the famed Summer Triangle asterism. Beta Lyrae is the prototype of a class of stars known as Beta Lyrae variables. These binary stars are so close to each other that they become egg-shaped and material flows from one to the other. Epsilon Lyrae, known informally as the Double Double, is a complex multiple star system. Lyra also hosts the Ring Nebula, the second-discovered and best-known planetary nebula.

The tip of the pyramid ends in a cuplike structure called the papilla.

Papilla projects into a calyx. Its surface has a sievelike appearance since it is where urine droplets pass through its small openings. Each opening represents a tubule known as the Bellini duct through which collecting tubules within the pyramid converge or meet. The muscle fibers lead from the calyx to the papilla. As the muscle fibers originating from calyx contract, urine flows through the Bellini ducts into the calyx. The urine flows through the renal pelvis and the ureter and it eventually drains down into the bladder.

Are genes a segment of DNA containing a set of instructions for making a protein ?

brilliants [131]

Answer: The given statement is True.

Gene can be described as the segment of DNA ( deoxyribonucleic acid), which codes for a particular protein. The protein thus formed, corresponds to a specific trait ( such as skin color, hair color, color of eye) of the individual organism.

They possess set of instructions for making a protein in the form of nucleotide sequences. Gene undergo transcription to form mRNA ( messenger RNA), which is then converted into particular protein through translation.

Genes are inherited from parents by their offspring and in this way specific traits are inherited by offspring from their parents.

Thus, given statement in the question is correct.

Sati [7]

The most ethical decisions for usage of genomic data and technology, like sequencing human genomes for customized treatments and constructing deadly pathogens for study, are based on Consensus.

<h3>Waht is Consensus in a scientific community?</h3>

It normally implies settlement of the supermajority, aleven though now no longer always . Consensus is executed via scholarly communique at conferences, the book process, replication of reproducible consequences through others, scholarly debate, and peer review.

In short, a systematic consensus tells us matters that we've already learned, and it shall be realized whilst matters have stopped being debated withinside the sciences.Scientific consensus is the collective judgment, position, and opinion of the network of scientists in a selected discipline of study.
