Answer:

Decodes the sequence of bases on the mRNA and then creates specifc proteins

Explanation:

Decodes the sequence of bases on the mRNA and then creates specific proteins. Therefore, option (A) is correct.

Ribosomes in eukaryotic cells are responsible for protein synthesis, a crucial process in which they decode the genetic information carried by mRNA molecules. Ribosomes read the mRNA sequence and use it as a template to assemble amino acids in the correct order, forming a polypeptide chain that folds into a functional protein. This process, called translation, occurs in two main subunits of the ribosome, which come together on the mRNA strand.

Ribosomes ensure accurate protein synthesis by matching each mRNA codon with the appropriate amino acid, guided by transfer RNA (tRNA) molecules. Ultimately, ribosomes play a central role in translating genetic information from DNA to create a wide variety of proteins that perform diverse functions within the cell and organism, making them essential components of cellular machinery. Therefore, option (A) is correct.

A balance is best used to measure the mass of a sample.

A balance is a device used to measure the mass of objects. The working principle of the most used scales today is based on Hook's Law. Scales are devices used to measure the mass of a body and are one of the oldest measuring instruments used by man.

Scale (from the Latin bis - two and linx - plate) is an instrument that measures the mass of a body. The usual unit for mass is the kg, as it is an SI unit. Therefore, it is correct to say that scales measure the masses of bodies and objects, not their weight.

With this information, we can conclude that Popularly, we are associating the measurement observed when we step on a scale with the word weight. This argument used by most people is totally wrong. The measurement obtained by stepping on the scale should be called mass, not weight.

Answer:

Botanical classification is the process of grouping plants based on their shared characteristics. The system of botanical classification is hierarchical, with plants being classified into increasingly specific categories.

The basic unit of classification is the species, which is a group of organisms that can interbreed and produce fertile offspring. Species are further classified into genera, which are groups of closely related species. Genera are then grouped into families, which are groups of genera that share certain characteristics, such as the structure of their flowers or the arrangement of their leaves.

Families are then grouped into orders, which are groups of related families. Orders are grouped into classes, classes are grouped into divisions or phyla, and phyla are grouped into kingdoms.

The true statements regarding adaptations of the human upper limbs for bipedalism are:
1. They are shorter than the lower limbs.
2. Good hand mobility allows for manipulating objects.

1. They are shorter than the lower limbs - This statement is true. One of the adaptations of the human upper limbs for bipedalism is that they are shorter than the lower limbs. This is because the lower limbs support the body weight and need to be longer to provide stability and balance, whereas the upper limbs are used for manipulation and do not require as much length.

2. Good hand mobility allows for manipulating objects - This statement is also true. One of the advantages of bipedalism is that it frees up the hands for manipulating objects. The human upper limbs are adapted for grasping, manipulating, and carrying objects, which is made possible by good hand mobility.

3. They are adapted for locomotion - This statement is somewhat ambiguous and could be interpreted in different ways. If by "they" we mean the upper limbs, then this statement is partly true. While the primary function of the upper limbs is not locomotion, they are still involved in the act of walking and provide balance and counterbalance during movement. However, if by "they" we mean the human body as a whole, then this statement is true. Bipedalism is a form of locomotion, and the human body is adapted for this mode of movement.

4. The shoulder joint has less mobility than the hip joint - This statement is false. The shoulder joint is actually one of the most mobile joints in the human body and allows for a wide range of movements, including flexion, extension, abduction, adduction, and rotation. In contrast, the hip joint is a ball-and-socket joint that provides stability and support but has less range of motion than the shoulder joint.

Answer:

Water

Explanation:

Proteins and carbohydrates go under dehydration synthesis.  In this process, hydroxide (OH) and hydrogen (H) of two monomers join together and the byproduct from this reaction is H2O. Hope this helps! Look up "dehydration synthesis" to learn more. This is not to be confused with hydrolysis, which adds water in order to break down polymers.

The synthesis of protein or carbohydrate polymers always produces water as by product because they are condensation polymers.

Polymerization refers to the joining of small molecules called monomers to form a larger molecule called a polymer. Polymerization may occur in two ways;

In condensation polymerization a small molecule such as water is lost in the process as the monomers are joined together. In addition polymerization, no small molecule is lost in the process.

Since proteins and carbohydrates are condensation polymers, a molecule of water is always lost when the polymers are formed.

The polar bear evolved from a common ancestor it shared with the brown bear millions of years ago. As some individuals of this ancestor population migrated to the Arctic, they developed advantageous traits to survive in the harsh Arctic environment, such as thicker fur, insulation, and improved hunting abilities in a marine environment.

Mutation: A genetic mutation occurred in a brown bear, leading to traits better suited for survival in a polar environment, such as thicker fur and adaptations for hunting in icy conditions.

Allopatric speciation: The brown bear population became geographically isolated, with some bears inhabiting colder regions like the Arctic. This separation prevented gene flow between the two populations and allowed them to evolve independently.

Natural selection: In the isolated polar bear population, individuals with advantageous traits for the Arctic environment, such as insulation and swimming abilities, were more likely to survive and reproduce. Over time, these traits became more common in the polar bear population.

Answer:

DNA stores the information for protein synthesis, and RNA carries out the instructions encoded in DNA.

DNA stores the information for protein synthesis, and RNA carries out the instructions encoded in DNA.

Cells create proteins through a process known as protein synthesis. Transcription and translation take place simultaneously. The conversion of genetic information from DNA to mRNA in the nucleus is known as transcription.

Initiation, elongation, and termination are its three stages.  Following processing, the mRNA transports the instructions to a ribosome in the cytoplasm.

The ribosome, which is made up of proteins and rRNA, is where translation happens. The mRNA's instructions are read during translation, and tRNA then transports the appropriate sequence of amino acids to the ribosome. rRNA then facilitates the formation of bonds between the amino acids, resulting in a polypeptide chain.

A polypeptide chain may be further processed to create the finished protein after it has been created.

Therefore, DNA stores the information for protein synthesis, and RNA carries out the instructions encoded in DNA.

Weather is defined as a mixture of events that occur every day in our environment that vary in different parts of the world and vary over a period of minutes, hours, days and weeks. Most of the weather occurs in the troposphere, the part of Earth's atmosphere that is closest to the ground.

Weather is controlled by changes in air pressure, so air pressure is caused by the weight of the large number of air molecules that make up the atmosphere. Thus, when the sky is clear and blue when the air pressure is high where high pressure causes the air to flow downward and when it reaches near the ground it prevents clouds from forming and when The air pressure is low so the air flows together and then moves upwards where it converges, rises, cools and forms clouds.

Answer: Bald Eagle

Explanation: The bald eagle was the first animal on the endangered species list.

The statement :"Mayflies belonging to the order Ephemeroptera get their name from the fact that they are here today, but gone tomorrow (so to speak)." is true.

The name Ephemeroptera comes from the Greek words "ephemeros" (short-lived) and "pteron" (wing), reflecting their short lifespan, usually ranging from a few hours to a few days, depending on the species.

Mayflies are aquatic insects found in freshwater habitats such as rivers, streams, and lakes. They are important indicators of water quality, as they are sensitive to pollution and changes in water chemistry. Mayflies play a crucial role in freshwater ecosystems, serving as a food source for fish and other aquatic organisms.

They are also important for nutrient cycling, as they consume organic matter and release nutrients back into the water. Despite their short lifespan as adults, mayflies spend most of their life as nymphs in the water, undergoing several molts before emerging as winged adults.
