a. Viruses with envelopes have two phospholipid bilayer membranes directly surrounding their genome, viruses without envelopes do not have phospholipid membrane
Viruses are composed of two main components: the viral genome (which can be RNA or DNA) and the virus-coded protein capsid that surrounds the genome.
If the virus particle contains only these two elements, it is called a non-enveloped virus. If the virus particle contains an extra lipid bilayer membrane surrounding the protein capsid, it’s called an enveloped virus.
The enveloped viruses are more virulent in nature since they cause cell lysis. Whereas the enveloped ones just enter a protein capsule by fusing with the host cell's lipid bilayer membrane. This makes them less virulent.

1. What makes Charles Darwin an important person to learn about?
Answer: Charles Darwin is an important person to learn about because he is the scientist who developed the theory of evolution by natural selection. This theory explains how species change over time through the process of natural selection, where individuals with traits that are better suited to their environment are more likely to survive and reproduce.
Darwin's theory of evolution by natural selection has had a profound impact on the scientific understanding of the natural world, and it is considered to be one of the most important scientific theories of all time. It has been supported by a vast body of scientific evidence and has helped to explain a wide range of phenomena in biology, including the diversity of life on Earth and the adaptations of organisms to their environment.
In addition to his contributions to science, Darwin is also an important figure in the history of science. He was one of the first scientists to systematically study and document the process of evolution, and his work laid the foundation for many of the advances that have been made in the field of biology over the past 150 years. His ideas have also had a significant impact on other fields, including psychology, sociology, and anthropology. As such, learning about Charles Darwin and his contributions to science can help us to better understand the natural world and the forces that shape it.
Which explains the role of a gene
The role of a gene is to transmit as physical and functional units the inheritance characters from one generation to the next.
What is a gene sequence?A gene sequence is a given fragment of a single strand of the DNA molecule which contains a specific linear order of nucleotides that is used to synthesize a cognate RNA molecule such as a messenger RNA or mRNA, a sequence that then serves as a template in order to generate a protein by a process called translation.
The genes are considered the physical and functional unit of inheritance because it contains the information to transmit a particular phenotypic character.
Therefore, with this data, we can see that a gene sequence is a given fragment of DNA that may serve to create a protein in the individual and it serves to transmit phenotypic features from parents to offspring.

the categories of skeletal muscle based on the type of metabolic pathway used for synthesis of atp are . multiple select question. glycolytic synaptic kinetic ionic oxidative
One molecule of glucose is converted into two molecules of pyruvate by the cytosolic process known as glycolysis, which also results in the net generation of two molecules each of ATP and NADH (nicotinamide adenine dinucleotide).
To refuel ATP in muscle, three energy mechanisms work: phosphoglycation, glycolysis, and mitochondrial respiration. While glycolysis and the mitochondria are in charge of cellular ATP synthesis, the sarcoplasmic reticulum (SR) is the main regulator of calcium storage, release, and reuptake in skeletal muscle. Due to their high energy needs, skeletal muscle cells have many mitochondria that enable them to produce enough ATP. The process by which cells produce ATP by dissolving the organic materials in food is known as cellular respiration. Muscle cells have the capacity to make ATP either by aerobic respiration, also known as breathing with oxygen, or through anaerobic respiration, also known as fermentation or anaerobic glycolysis.

sexual selection in a population choose one: a. can lead to physical differences between the males and females of a species. b. does not lead to evolution. c. reduces genetic variation in the population. d. always favors individuals with a higher survival potential.
The right response is option a, which states that morphological distinctions between males and females of a species can result from sexual selection in a population.
The tail of a peacock is a good illustration of partner selection. Peahens choose peacocks with huge, vibrant tails, which allows those peacocks to mate more frequently and produce younger ones. The genes for a long, colourful tail will be passed down from the father to the male peachicks, who will inherit these genes and develop comparable tails. There are two main factors that influence sexual selection. One is the preference of one sex (typically females) for members of the opposite sex who display particular features. The other is higher strength, which (often in males) results in better success in courting females.
So, we can conclude that option a, which claims that sexual selection can lead to physical differences between males and females of a species in a population, is the appropriate response.

The following picture shows the three primary types of plate boundaries. Which boundary is being shown in label D? Oconvergent boundary zone ODivergent boundary zone Oplate boundary zone Otransform boundary zone
The type of plate boundary which is shown in label D in the picture is convergent boundary.
What is convergent boundary and what are its features?Two plates travelling in the opposite directions clash at a convergent boundary. The less dense plate, usually the continental plate, is subducted beneath the denser plate, which is often the oceanic plate. The plates often stretch downward at the boundary as a result of the tremendous stress from the subduction, leading to the formation of an oceanic trench.
Volcanic arcs, which are chains of volcanoes, are a typical feature of convergent boundaries. These are created by the fractures that occur at the border brought on by the stress between the two plates. The melting of the subducted plate causes the magma to rise through the fractures as it descends into the mantle. A volcanic mountain is formed at the surface by the magma. There will grow a number of mountains (a mountain chain) as a result of the boundary's multiple cracks.

when using the microscope for an intravaginal infection you see something translucent and colorless, what do you suspect?
When using the microscope for an intravaginal infection, you might sometimes spot a translucent and colorless substance, called hyphae.
Garden hose-like hyphae are protracted tubular formations. They feature solid cell walls that might perhaps be strengthened by septa, which are perforated cross-walls (singular: septum). In fungi, hyphae help in a number of processes. They include the nuclei that contain the genetic material as well as the cytoplasm, or cell sap.
Hyphae carry nutrients from the environment to different areas of the thallus (fungus body). In the end, they could unite or undergo modifications to create more intricate structures. Only a very tiny percentage of yeasts do not generate hyphae, but the bulk of fungi do.

Option B - Whenever roasting beef that contains a lot of collagen, To make gelatin, cook the collagen using a wet heat method.
At 160/70, collagen begins to break down into gelatin. The meat becomes dryer, but at 160F the collagen-containing connective tissues start to turn into gelatin. Muscle fibers that had been tightly bound start to easily stretch apart over time. The flesh appears more tender because of the succulence that the gelatins produce, despite the fact that the fibers are still very stiff and dry.
Therefore, we want our meat to be cooked tenderly so that the rough collagen is transformed into gelatin while minimizing moisture loss. The fact that these techniques conflict with one another is what makes cooking meat difficult or problematic. However, temperatures must be lower than 130F in order to avoid moisture loss.
