Answer:

C

Explanation:

Height in humans is influenced by numerous loci and has a relatively smooth distribution. It is thus a quantitative or continuous trait.

A quantitative trait locus (QTL) is a DNA territory correlated with a specific phenotypic trait that differs in extent and can be linked to polygenic effects, i.e. the product of two or more genes, and their habitat.

Label the figure below. Word bank: leading strand, lagging strand, DNA
Natalija [7]

Answer:

DNA can replicate itself because its two strands are complementary. This means that one strand can be used as a template to make the other strand. It happens right before cell division via mitosis or meiosis so that each new daughter cell can have a complete genome.

Before replication can start, the double strands of DNA need to separate from each other. An enzyme called DNA helicase breaks the hydrogen bonds that connect the two strands, allowing them to come apart.

The point where this unzipping starts is called an origin point. Eukaryotic DNA can have more than one origin point, but prokaryotes can only have one.

The points where DNA is currently unwinding are called replication forks.

A forensic scientist in using a standard biological microscope with 15 objective and 5 eyepiece to examine a hair from a crime s
SIZIF [17.4K]

The given data is Magnification, M = 15

Length of the tube , L = 16 cm

The focal length of the lens can be calculated by:

M = L/F

Substituting the value, we get:

15 = 16/f

f = 16/15

f = 1.067 cm

Using the equation of magnification we get,

M = v/u

Substituting the values we get:

15 = v/u

v = 15 u

With the help of lens formula, calculate the object distance:

1/f = 1/v + 1/u

Substituting the value we get,

1/1.067 = 1/15u + 1/u

0.937 = 1.067/u

u = 1.13 cm or 1.1 cm.

Hence, the object distance is 1.1 cm.

Which is the term for numbers that appear in the chemical formulas of some compounds?
iogann1982 [59]

It is called subscript indicating the number of atoms.

Explanation:

The chemical compound is formed by two or more elements.

The compound is formed by the sharing, accepting or donating the electrons.

The compound formed by two elements will have different valencies of cations and anions.

In chemical formula of compound specific number of atoms of each element are present.

eg: H2O (2 atoms of hydrogen bonded with one atom of oxygen)

       NaCl  (1 atom of sodium and one atom of chloriine are bonded.)

     NaHCO3 ( 1 atom of sodium, 1 atom of hydrogen, 1 atom of carbon and 3 atoms of oxygen.)
