Which of the following is NOT part of the non-specific immune response?
A. Inflammation
B. Phagocytosis
C. Antibodies
D. Interferons
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).

I'm working on an assignment and they all seem true to me. Help?
Which of the following statements about plants is not true?
a. They make their food from carbon dioxide and water through photosynthesis.
b. Land plants have cell walls that help hold their stems upright.
c. They have adaptations that help prevent water loss.
d. Plants absorb food through their roots.
Answer:
A
Explanation:
because plants use atmospheric carbon dioxide and water absorbed from the earth to create organic matter in the process of photosynthesis. On that occasion, oxygen is released.
Answer:
A
Explanation:
I hope this is correct, since every other version I've seen of this question option A is water and oxygen.
the three steps that are required for dna replication are
Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment.
The three steps that are required for DNA replication are initiation, elongation and termination.
What is DNA replication ?The process in which DNA of a cell under go duplication to produce two copies during S-phase of cell cycle called as DNA replication.
It involves 3 steps such as initiation step where the origin of replication of DNA molecule undergo unwinding into two DNA strands.
An incomplete unzipping by forming replication fork is created is catalyzed by the helicase enzyme.
Secondly in elongation step the DNA polymerase enzymes make the complementary sequence against each parent template strand.
It is an unidirectional, one strand which is synthesized in a continuous manner called leading strand, the strand which is synthesized in a discontinuous manner called lagging strand with Okazaki fragments.
Termination occurs in the last step, when the parent molecule has been completely replicated.

Clouds form when the water vapor in air condenses as
Answer:
Clouds form when the invisible water vapor in the air condenses into visible water droplets or ice crystals. For this to happen, the parcel of air must be saturated, i.e. unable to hold all the water it contains in vapor form, so it starts to condense into a liquid or solid form.

Which of the following sentences state a significant conclusion that Gregor Mendel drew from his experiments with pea plants? Traits are inherited in discrete units and are not the result of "blending." Genes are composed of DNA. Recessive genes occur more frequently in the F1 generation than do dominant ones. There is considerable genetic variation in garden peas.
Mendel concluded that the alternative forms of each trait are coded by discrete factors, which were called alleles that combine in pairs to express the trait. Traits are inherited in discrete units and are not the result of "blending."
------------------------
After making many crosses that involved different traits -such as plant height, or flower colors-, Mendel observed that, per trait, the F1 only expressed one of the alternative forms, while de other one disappeared.
Mendel named dominant the expressed variant.
Mendel then let these new plants auto pollinate and observed the results in the second generation, F2.
He saw that the variants that had previously disappeared among the F1, reappeared again. Both alternatives for each trait were present in the F2.
Mendel named recessive the second alternative variant.
Mendel explained his results by arguing that discrete factors were responsible for these phenotypes.
These factors should have been present in the F1 in pairs. One of them came from one parental plant, and the other factor came from the other plant. These factors separated again during sex cells formation, producing two types of gametes, each with only one factor.Mendel conclusion about his experiments was that per trait -flower color of plant length-, each plant had a pair of factors -which he named alleles-, and that each factor coded for one of the alternative forms of the traits -white or purple, tall or short-.
He thought that alleles separate -segregate- during the process of gamete formation.
The First Mendel's Law is the first conclusion he took about his experiments and is known as the segregation principle.

how do you propagate trees
Answer:
The simplest method of propagating a tree vegetatively is rooting or taking cuttings. A cutting (usually a piece of stem of the parent plant) is cut off and stuck into soil.
Remove any flowers or fruit on the cutting. Trim the stem to just below where the bottom most leaf meets the stem. On each of the leaves on the stem, cut off half of the leaf. Put the end to be rooted.
