what is the general term used to describe the viral component that binds to a host cell for attachment?
Answers
Viral receptors are the general term used to describe the viral component that binds to a host cell for attachment purposes.
When referring to a particular molecule or structure that aids in viral attachment on the surface of host cells, the word "receptor" should be used. The molecule(s) on the surface of the virus that binds to the receptor is referred to as "ligands." The term "viral envelope" refers to the structure that surrounds the capsid of certain viruses. All viruses use a specific type of glycoprotein to bind to viral receptors on their host cells, which are cellular molecules.
Once a virus has attached itself to and entered the host cell by breaking through the cell wall or membrane, viral replication can start. The protein covering the viral genome is removed, and the viral genome is then injected into the host cell.

which movement of the head and neck would lengthen the fibers of the levator scapula on the right side of the body?
Answers
Rotation to the left of the head and neck would lengthen the fibers of the levator scapula on the right side of the body.
The Levator Scapulae, an Axio-Appendicular muscle in the posterior triangle of the neck, attaches the upper limb to the spinal column. The sternocleidomastoid and trapezius protect the superior and inferior sides of the levator scapulae, respectively.
The levator scapulae raise the scapula and rotate it down to tilt the glenoid cavity inferiorly. If the scapula is stationary, levator scapulae contractions cause the cervical vertebral column to lateral flex to the side, stabilizing the vertebral column during rotation.

when the amygdala jumpstarts stress-related networks peripheral to the central nervous system, what part of the body releases the chemicals such as adrenaline that produce energizing effects?
Answers
Adrenaline is produced in the medulla by the adrenal glands as well as by some neurons in the central nervous system. During a stressful situation, adrenaline is quickly released into the bloodstream, sending impulses to organs to create a specific response.
The adrenal medulla, the innermost part of the adrenal gland, regulates the hormones that initiate the flight or fight response. The adrenal medulla secretes two main hormones: epinephrine (adrenaline) and norepinephrine (noradrenaline), which have similar functions. Adrenaline is produced by your adrenal glands and released into your bloodstream. Adrenaline, a hormone produced by your adrenal glands, serves a purpose.

what waste product do yeast produce under anaerobic conditions? what waste product do yeast produce under anaerobic conditions? lactic acid ethyl alcohol pyruvic acid creatine
Answers
Yeast produces carbon dioxide and ethyl alcohol when it is anaerobic.
They do this through a process known as fermentation in which glucose molecules are consumed. Because the carbon dioxide produced during the baking process aids in the bread's rising, yeast is added.
What about anaerobic conditions?When the intake or loss of oxygen exceeds that of its production through photosynthesis or diffusion by physical transfer from the surrounding environment, anaerobic conditions are present. Due to the availability of organic material, microbial respiration typically consumes oxygen. A set of metabolic processes allow cells to regenerate their energy under anaerobic conditions. Fermentation is the name given to this process. The Krebs cycle is stopped when there is an anaerobic environment. Clostridium botulinum and the microorganisms that dwell close to hydrothermal vents on the deep-sea ocean floor are two examples of obligate anaerobes. Organisms that can tolerate the presence of oxygen but cannot use it for growth. Anaerobes that can develop in the absence of oxygen yet use it when it is available.

how do ionizing radiation, ultraviolet radiation, and visible light harm microorganisms? how do microorganisms protect themselves against damage from uv and visible light?
Answers
Microorganism protect themselves against harmful UV light and visible light by using Iron minerals around themselves.
The iron minerals have unique properties in that they block damaging UV radiation while yet allowing organisms to utilise the portion of sunlight required for photosynthesis. UV rays kill cells by damaging their DNA. Two molecules of thymine, one of the bases that makes up DNA, react when exposed to light. The thymine dimer that results is extremely stable. The cell cannot perform its usual tasks if cellular processes are interfered as a result of an inadequate repair or unrepaired damage of thymine dimer.

Species richness (S) is the number of species within a defined region. It's merely a numerical characteristic of an ecosystem. The species richness of a region is obtained through sampling or via a census.
Because a region is defined by the observer, species richness has been further categorized into three components to account for changes in spatial scale. They are Alpha diversity, Beta diversity and Gamma diversity.
One important thing to keep in mind is the difference between species richness and species diversity.

describe the mechanisms that ensure parental and daughter duplexes have identical DNA sequences
Answers
The mechanism that ensures parental and daughter duplexes have identical DNA sequences is the replication process. It occurs before cell division and provides each daughter cell with the same chromosomic set as the parental cell.
What is DNA replication?
DNA replication is a process through which DNA molecules are duplicated. It occurs during the S phase of the interphase, before cell division.
In the interphase the cell duplicates its content, so every daughter cell gets the same material. Hence, DNA must be replicated, so daughter cells have a complete chromosomic set.
DNI replication is semi-conservative because each new molecule carries an original DNI strand and a new one. The old existing strands are used to synthesize the new complementary strand.
To separate the original strands, helicase enzymes must act in the replication origin to break hydrogen bonds and separate the strands.
While the strands unroll, the topoisomerase enzyme releases tension.
Other proteins are also needed to join the strains and keep them separated.
Once the molecule is opened, there is a region named replication forks. DNA polymerase pairs new nucleotides with the corresponding nucleotide of the original strand.
DNA strands are antiparallel, and replication occurs only in 5'-3' direction. One of the strands is continuously replicated, while the other strain grows in short Okazaki fragments.
