Muscle cells are generally considered to be in a state of permanent cell cycle withdrawal known as G0, where they remain quiescent and do not actively divide. Certain external signals can induce muscle cells to re-enter the cell cycle and initiate proliferation.

Muscle cells, also known as myocytes, are specialized cells responsible for the contraction and movement of muscles in the body. These cells possess unique features that allow them to generate force and enable various types of movements.Muscle cells contain specialized proteins called actin and myosin, which interact to create the contractile force required for muscle movement. These proteins form organized structures known as sarcomeres, which are the fundamental units of muscle contraction.

Muscle cells come in different types, including skeletal muscle cells, cardiac muscle cells, and smooth muscle cells. Skeletal muscle cells are attached to bones and facilitate voluntary movements. Cardiac muscle cells make up the heart and are responsible for its rhythmic contractions. Smooth muscle cells are found in organs such as the digestive tract and blood vessels, contributing to involuntary movements.Muscle cells also possess high energy requirements and contain abundant mitochondria to generate the necessary energy through cellular respiration.

Broad-sense heritability (H^2) is a measure used in genetics to estimate the proportion of phenotypic variation in a population that can be attributed to genetic factors. It is expressed as a value between 0 and 1. A broad-sense heritability of 0.8 means that 80% of the observed variation in the trait can be explained by genetic differences among individuals, while the remaining 20% of the variation can be attributed to environmental factors and their interaction with genetic factors. In other words, a higher heritability value suggests that genetic factors play a more significant role in determining the expression of that trait in the population.

Eudicot leaves cannot be processed with decortication to isolate their fibers because they lack a distinct fibrous layer. Decortication is a process that involves separating the outer layer of a plant material from its inner layer, to obtain fibers for various applications. However, in eudicot leaves, the fibers are embedded within the leaf tissue and are not readily accessible for extraction. Additionally, the fibers in eudicot leaves are short and do not have the strength and durability needed for industrial applications.

In contrast, monocot leaves such as those from the pineapple plant are rich in long, strong fibers that can be easily separated through decortication. These fibers are commonly used for making textiles, ropes, and other products. While eudicot leaves may not be suitable for fiber extraction through decortication, they still have important roles in the ecosystem as well as in medicine and human nutrition.

Given the above DNA template, the mRNA, tRNA and amino acid is as follows:

Gene expression is the transcription and translation of a gene into messenger RNA and thus into a protein.

Transcription is the synthesis of RNA under the direction of DNA while translation is the process whereby a strand of mRNA directs assembly of amino acids into proteins within a ribosome.

Messenger RNA (mRNA) is the RNA that encodes and carries information from DNA during transcription to sites of protein synthesis to undergo translation in order to yield a protein.

Transfer RNA (tRNA) is the short-chain version of RNA that transfers individual amino acids to ribosomes during protein synthesis.

The transfer RNA is similar to the template DNA, with the difference being that Thymine (T) base is changed to Uracil (U).

The corresponding amino acids derived from the codon of each mRNA is depicted in the main answer part.

The whole process of protein synthesis involves transcription -mRNA synthesis- and translation -protein building-. In the exposed examples,  Amino Acids: ILE - ALA - ILE - ARG - LEU - GLN - STOP. Amino Acids: ILE -  PHE - LYS - PRO - GLY - STOP.

Transcription and translation are two processes involved in protein synthesis.

Transcription is mRNA synthesis. It occurs in the nucleus and copies -transcribes- a fragment of the DNA template strand to carry genetic information to the cytoplasm. This information is necessary to build a protein.

During transcription, mRNA complements DNA base sequences. Nucleotides are added to the growing molecule in a way that

Once mRNA synthesis is completed, the molecule leaves the nucleus toward the cytoplasm where protein synthesis occurs.

Translation occurs in the cytoplasm and is the process through which rRNA and tRNA read the genetic information in mRNA and build the protein by following the mRNA codon sequences and adding the correct amino acids.

While rRNA moves along mRNA, the associated tRNA recognizes mRNA codons and adds the amino acid to the chain.

In the exposed example,

DNA Template     TAG   CGT   TAT   GCC   AAC   GTC   ATT

When resources are unlimited, the population exhibit exponential growth. The exponential growth of the bacterial population indicates a rapid increase in the population of bacteria due to favourable Conditions.

The curve in the graph indicates the situation in which the population density of the bacteria increases rapidly in an exponential manner in the new environment. Exponential population growth occurs when there is no limit to the population size, exactly what is happening in the above graph.

A constant rate of increase for population growth produces an exponential growth curve called a J-shaped curve rather than a straight line because the population increases its number per unit of time, hence the curve gets steeper as time increases.

This type of curve is called an exponential growth curve or J- shaped growth curve. When resources in the habitat are unlimited, each species can realise fully its innate potential to grow in number and hence increases its population to the maximum.  Hence, the growth of the curve is exponential so the graph is called an exponential growth curve.

Weathering and erosion constantly change the rocky landscape of Earth. Weathering wears away exposed surfaces over time. The length of exposure often contributes to how vulnerable a rock is to weathering. Rocks, such as lavas, that are quickly buried beneath other rocks are less vulnerable to weathering and erosion than rocks that are exposed to agents such as wind and water.

Explanation:

Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away. No rock on Earth is hard enough to resist the forces of weathering and erosion. Together, these processes carved landmarks such as the Grand Canyon, in the U.S. state of Arizona. This massive canyon is 446 kilometers (277 miles) long, as much as 29 kilometers (18 miles) wide, and 1,600 meters (1 mile) deep.
