D. Interferons are not a part of the non-specific immune response.
What is the function of interferons?Interferons were first described as an antiviral thing that interferes with viral replication in mammalian cells (10). they're secreted from inflamed cells and spark off an innate immune reaction that promotes now not best cytokine production but additionally herbal killer mobile features and antigen presentation.
Interferons (IFNs) — the body's first line of antiviral defense — are cytokines that are secreted by host cells in reaction to virus infection. by using inducing the expression of hundreds of IFN-inspired genes, numerous of that have antiviral capabilities, IFNs block virus replication at many ranges.
Interferons are a circle of relatives of clearly-happening proteins which are made and secreted with the aid of cells of the immune gadget (an example, white blood cells, natural killer cells, fibroblasts, and epithelial cells).

What is cell cycle?
Cell cycle is defined as cycle in which cell produces, grows and divides. The cell cycle has mainly three steps the first one is G1 phase in which the size of cell increases, S phase synthesis of DNA takes place and the third step is G2 phase in which cell ready to divide.
Cell is defined as the base of life as it is the structural as well as functional unit of life. Cell is made up of pre existing cells and the cell contain various cell organelles such as mitochondria, endoplasmic reticulum, ribosomes, golgi appratus, nucleus, and cytoplasm.
Basically, cell is of two type one in prokaryotic and another one is eukaryotic. The prokaryotic cell is known as pre mature cells as they do not contain cell organelles and eukaryotic cell are known as advanced and developed cells as they contain several cell organelles.
Therefore, Robert Hooke was the first person to observe cells. He observed these cells in a piece of cork. Thus, option A is correct.

What amino acids is represented by the codon UUA?
Answer:
Leucine
Explanation:
Leucine amino acid is represented by the codon UUA. One codon codes for only one amino acid.
What are amino acids?Proteins are made up of substances called amino acids. Proteins and amino acids are the components of life. Amino acids are the byproducts of the digestion or breakdown of proteins. Amino acids are used by the human body to create proteins that aid in breaking down food.
There are 20 amino acids, of which 10 amino acids are essential and 10 are non-essential amino acids.
Codons made from three nitrogenous bases codes for amino acids. One amino acid can be coded by more than one codon, while one codon can code only one amino acid. For example, UUA codes only for leucine, but leucine can be coded by UUA, UUG, CUA, CUC, CUG, and CUU.

State 2 of Newtans three laws
(PLS HELP ASAP!!)
1. Something at rest or in motion in all constants will remain that way unless acted upon by a force.
2. F=ma
Explanation:
Newton’s first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.
Force equals mass times acceleration; it states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it.

Analyses of the protein ______ can be used to study evolutionary relationships among species because most organisms produce this protein for the electron transport chain in mitochondria.
Evolutionary relationships among species can be studied when similar structures or materials eg the wings of a bat and the arm of a bird or similar proteins between two different species. This proves to show relationship among organisms.
Analyses of the protein Cytochrome C can be used to study this types of evolutionary relationships.
Cytochrome C is an antioxidative enzyme that is a part of the electron transport chain in mitochondria. Mitochondrion is an organelle that majority of living organisms share in common. This protein is therefore found present in almost all organism carrying out cell respiration.

A bacteriophage attaches itself to a susceptible bacterium and infects the host cell. Following infection, the bacteriophage hijacks the bacterium's cellular machinery to prevent it from producing bacterial components and instead forces the cell to produce viral components.
why renin is found more in case of babies
can someone answer it
Answer:
newborn infants. Bioassayable andimmunoassayable renin activities were elevated during the first six days after delivery. At 3 to 6 weeks of age, although elevated above that in adult control subjects, renin activity was lower than in the first postnatal week. Cord blood renin values were greater than those for maternal renin during labor. Renin substrate concentration was elevated in infants less than six days of age and also in 3- to 6-week-old infants. The enhanced activity of the renin-angiotensin system may contribute to the increased renal vascular resistance and the altered renal hemodynamics that occur in the newborn infant.

evaluate the statements below and determine which is the best reason that bacterial cells use operons and polycistronic rna.
Given what we know about bacterial cells and their genetic mechanisms we can confirm that they use operons and polycistronic RNA for efficiency.
Bacterial cells are vastly different from human or animal cells. Some of these differences include:
Lack of compact DNALack of organelle surrounded by plasmatic membranesThey have cell wallsMay possess flagellaand many others.
Among these differences is the way in which they encode for the proteins the bacteria will produce. Unlike human cells, bacteria use polycistronic RNA. Where a human strand of mRNA will carry the genetic message to create one protein, the polycistronic mRNA of a bacterial cell will provide the information necessary to create multiple distinct proteins.
Bacteria use this in conjunction with operons, to create very efficient protein manufacturing processes. Operons are sections of DNA in which proteins with similar functions are grouped together in order to make it easier to create the polycistronic mRNA strands.

Answer:
1. A rock falling off a cliff
2. Roller coaster starts plummeting from the top
3. Pendulum swings from the top to the middle, once it starts the second up swing the kinetic turns back into potential energy
Answer:
1. Pushing a large rock down a hill.
2. Kicking a stationary soccer ball.
3. Releasing a taut rubber band
I don't know how varied your class's examples of potential energy have been so far, but there are many kinds if you need more variety.
Explanation:
You can just use your imagination for these if you want to! Potential energy is the energy that an object can have, its potential to have energy (just like it says), while kinetic energy is the energy of a moving object. All you need to do is take a still object and apply force to it.
blood flows more slowly in the capillaries than in the aorta. why?
Answer:
because it a smaller part
Explanation:
Due to the capillaries' large overall cross-sectional area, blood flow there is slow, allowing for adequate nutrition exchange.
How blood flows through blood vessels?The rate of blood flow dramatically decreases as it enters arteries, arterioles, and eventually, capillary beds, slowing to roughly 0.026 cm/sec, or 1,000 times slower than the aorta.
The capillaries, where blood flow is the slowest, provide time for the exchange of gases and nutrients. A force that opposes a fluid's flow is called resistance.
The majority of blood vessel resistance is caused by the size of the vessel. Blood flow reduces as vessel diameter shrinks due to an increase in resistance.
Therefore, the high total cross-sectional area capillaries blood flows more slowly.
