Answer
The various steps in the transcription and translation process of protein synthesis are described below.
Explanation:
Proteins (made up of amino acids) have an important role in the various functioning process of an organism. Protein synthesis which takes place in the cells of an organism consists of two major processes: transcription (DNA to RNA) and translation (RNA to protein).
Transcription: It is the first process in protein synthesis which occurs in the cell nucleus where a single-stranded messenger RNA (mRNA) is created using a DNA strand and the genetic instructions in DNA are transferred to this mRNA. The steps in transcription are initiation, elongation, and termination. The beginning process known as initiation occurs when an enzyme RNA polymerase binds to a promoter (region of a gene) and the DNA unwinds. One of the DNA strands acts as a template and the enzyme reads the bases in the template DNA strand.
The next step is elongation, where the RNA polymerase builds a strand of mRNA by the addition of nucleotides using complementary base pairs. Here, adenine (A) in the DNA binds to uracil (U) in the RNA. Termination is the last step in which the transcription process ends when the RNA polymerase comes across a termination sequence in the gene. Thus, the completed single-stranded mRNA detaches from DNA.
Translation: It is the second process in protein synthesis which occurs in the ribosome of the cell where the genetic information in mRNA is used to create a protein from amino acids. A triplet of nucleotides is called a codon and they define amino acids. There are 64 possible codons and the codon, AUG acts as the start codon which initiates translation in addition to specifying the amino acid methionine. In the initiation step, the first amino acid in the polypeptide chain is brought by transfer RNAs (tRNAs) to bind to the start codon of mRNA. During elongation, each type of tRNAs in the cytoplasm bound to a specific codon on the mRNA template and adds the corresponding amino acid to the polypeptide chain. Stop codons (UAA, UAG, or UGA) terminate protein synthesis and release the polypeptide.
Neural crest cells appear on the edges of the neural tube and spread throughout the embryo, giving rise to all of the following structures except __________. Neural crest cells appear on the edges of the neural tube and spread throughout the embryo, giving rise to all of the following structures except __________. pharyngeal slits (or clefts) of invertebrate chordates some of the bones and cartilage of the skull sensory capsules in which eyes and other sense organs develop. teeth
Answer:
The correct answer is ''pharyngeal slits (or clefts) of invertebrate chordates.''
Explanation:
The neural crest is a temporary structure that develops as the neural tube closes. Its migratory capacity and subsequent distribution during development is a basic point in the general embryonic development and of most organs and structures in particular.These cells contribute to the formation of head cartilage and tooth dentin in fish embryos; and a large number of tissues and structures are formed from the migration of neural crest cells. Invertebrate chordates are animals of the Chordata phylum that have a notochord at some point in their development, but do not have a backbone. With a hollow nerve cord, neural tube. It appears by invagination of the dorsal surface; the tube is formed with a central cavity lined by ependyma; the anterior part of the neural tube gives rise to the brain. The neurenteric canal is a communication channel between the neural tube cavity and the intestine. The pharyngeal clefts (pharyngotremia), originally used for food; It is a filtering device that retains food particles that are included in mucus and transported to the intestine. In fish it already acquires respiratory function. In the ventral part, a groove is formed with cilia and bands of glands: endostyle or hypobranchial groove.

the foxes will see the greatest decrease in energy as the squirrels are their only prey.
Explanation:

In food web, foxes would see the greatest decline in energy availability if a pesticide removed the majority of the squirrel population.
What do you mean by food web?A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community. Another name for food web is consumer-resource system.
Food web is an important conceptual tool for illustrating the feeding relationships among species within a community, revealing species interactions and community structure, and understanding the dynamics of energy transfer in an ecosystem.
A food web consists of many food chains. A food chain only follows just one path as animals find food. Example- A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass.

In prokaryotic cells, the DNA is found-
A)Attached to the ribosomes.
B)Floating in the cytoplasm.
C)Contained in the vacuole.
D)Surrounded by the nuclear membrane.
Answer: B. Floating in the cytoplasm
Explanation: Prokaryotic cells do not have a nucleus or any membrane bound organelles. Therefore the DNA just floats.

Answer:
Glucose ,Fructose ,Ribose ,- monosaccharide..They have Carbon atoms 3 to 6 .They will not be further simplified
Sucrose-disaccharide firmed by Glucose and fructose .Two hexose sugar united together by glucoside linkage by the elimination of one water molecule.Glucose is aldalose having CHO aldehyde group and fructose is Ketose having C=O keto group sugar both are having same embrical formulae but different structural formulae
Lactose is a disaccharide glucose+glucose by glycoside linkage

The active ingredients in many pesticides are chemical compounds that kill organisms such as insects, molds, and weeds. Proponents claim that the use of pesticides improves crop yields and thus protects land and soil by reducing the conversion of forests and wetlands to cropland. Opponents of pesticide use claim that pesticides degrade water and soil quality and that other modern agricultural techniques and practices are responsible for the improved crop yields in recent years. Design a laboratory experiment to determine whether or not a new pesticide (product X) is toxic to minnows, a type of small fish.
Answer:
The active ingredients in many pesticides are chemical compounds that kill organisms such as insects, molds, and weeds. Proponents claim that the use of pesticides improves crop yields and thus protects land and soil by reducing the conversion of forests and wetlands to cropland.
Explanation:
The experiment design would be based on the hypothesis - that higher concentration of the new pesticide product X will result in more mortalities of minnows in the population.
Experiment:
In such type of experiment we required four different tanks with fresh water in each of them and 20 minnows in each as well.Tank 1 with no pesticide would be control in this experiment.concentration of the pesticide in tank 2: 0.05 %, tank 3: 0.1% and tank 4: 0.2%.number of death of minnows in each tank would be count after exposure every day.Experiment should be continue for 30 daysindependent variable: concentration of pesticidedependent variable: number of deaths of minnows each day of exposure.On the given design of the test we can determine whether or not a new pesticide (product X) is toxic to minnows, a type of small fish.

what is the difference between an alligator and a crocodile
Snout Shape: Alligators have a wide, rounded, u-shaped snout, while crocodiles have long, pointed, v-shaped snouts. ... Crocodiles are different from alligators in this sense, where both upper and lower jaws of a crocodile are the same size, exposing their teeth as they interlock, creating the look of a toothy grin.
Alligators have U-shaped faces that are wide and short, while crocodiles have thin V-shaped muzzles. When an alligator closes its mouth, you tend to see only its upper teeth. Crocodiles on the other hand flash a toothy grin with their top and bottom teeth interlacing.

Normal red blood cells slide easily through narrow blood vessels. In sickle cell disease, many red blood cells change to a crescent shape like a slender moon. Crescent-shaped blood cells cause blockages in blood vessels. These blockages decrease the transport of oxygen. People with sickle cell disease often have sharp pains due to the lack of oxygen in parts of the body. The sickle cell version of the gene that causes sickle cell disease is recessive. Suppose that two parents with no symptoms have a child with sickle cell disease. What genes did the child inherit from the parents?
Answer:

Explanation:
Normally, the flexible, round red blood cells move easily through blood vessels. In sickle cell anemia, the red blood are shaped like sickles or crescent moons. These rigid, sticky cells can get stuck in small blood vessels, which can slow or block blood flow and oxygen to parts of the body.
