Answer:

The correct answer is - chromatin.

Explanation:

Chromatin is a part within a chromosome consisting of DNA and protein. The DNA carries the cell's genetic instructions and these are complex structures present in multiple linear chromosomes.

The major proteins in chromatin are histones, which help package the DNA in a compact form that fits in the cell nucleus.

Answer:

In Gregor Mendel's work with pea plants, he found that when a tall pea plant, with genes TT, was crossed with a short pea plant, with genes tt, that _100_ % of the first generation of offspring plants were tall pea plant_.

Explanation:

After crossing the two types of plants, Mendel observed that among the F1 there were only tall variants, while the other variant (short) 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 short variant that had previously disappeared, reappeared again. Both tall and short plants 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 then separated again when sex cells were produced, giving two types of gametes, each with only one factor.

Mendel concluded that each plant had a pair of factors -which he named alleles-, and that each factor coded for one trait -tall and short-. He thought that these factors -T and t- separate -segregate- during gamete formation. This conclusion is known as the segregation principle (First Mendels´ Low).

Answer:

it should be G-G-A-G-C-T-A-A-G-T-G-C

Explanation:

A=T

C=G

think of them as opposites. invert them and you'll have the answer (its easier if you write the answer right underneath)

The amino acid sequence should be G-G-A-G-C-T-A-A-G-T-G-C

G-G-A: glycine

G-C-T: alanine

A-A-G: lysine

T-G-C:  tyrosine

Amino acids are molecules that combine to form proteins. Amino acids and proteins are the building blocks of life.

The nucleotide triplet that encodes an amino acid is called a codon. Each group of three nucleotides encodes one amino acid. There are 64 combinations of 4 nucleotides taken three at a time and only 20 amino acids, the code is degenerate (more than one codon per amino acid, in most cases).

C) Coronary artery disease can reduce blood flow to the heart and cause heart attacks

CAD (or atherosclerosis) affects the vessels that supply blood to the heart muscle. It is caused by deposits of calcium, fat, cholesterol and fibrous tissues, which makes the lumen of arteries narrower. And due to inadequate supply of blood, the heart muscles get damaged. This can lead to a heart attack!

Central banks control and manipulate the national money supply: issuing currency and setting interest rates on loans and bonds.

Explanation:

To ensure a nation's economy remains healthy, its central bank regulates the amount of money in circulation. Influencing interest rates, printing money, and setting bank reserve requirements are all tools central banks use to control the money supply.

Contact metamorphism is the result of rising of hot magma, where by contact, other previously solidified rocks also metamorphize. This events occurs in convergent and divergent plate boundaries.

-------------------------------------

Contact metamorphism refers to a localized metamorphism. It occurs in the vicinity of intrusive igneous rocks and results from the term effects of hot magma.

Contact metamorphism occurs under elevated temperatures and low-pressure conditions. It is closely related to magmatism.

It occurs in oceanic dorsals, where the extremely hot magma rising to the surface metamorphizes other previously solidified magmatic rocks.

It is very common to find this metamorphism at both convergent and divergent plate boundaries, where molten rock is produced.

I. Convergent. Collision area between two plates. Two oceanic plates might collide, or one oceanic plate with a continental one. In this last case, the oceanic crust sinks under the continental plate, and magma rises to the surface by crevices. The thicker and older plate subduces under the other plate. Also, collisions create volcanic arches and continental arches. In these boundaries, blueschists form by contact and regional metamorphisms.

II. Divergent: New crust is created by the rising molten materials coming from the mantle when two plates separate. A stream of hot material creates a new seabed between the separating plates, producing the sea bottom expansion. This process occurs along with an underwater mountain range, known as the mid-oceanic ridge or divergent ridge. Chlorite and plagioclase metamorphic rocks are formed by contact metamorphism.

Answer:

d. calculated = 3.10; critical = 7.815.

Explanation:

To test the hypothesis Given in the question above, we use the Chisquare goodness of fit :

The test statistic is defined as :

χ² = Σ(Observed - Expected)² / Expected

Observed = number of nests

χ² = ((15 - 19.9)^2 / 19.9) + ((29 - 25)^2 / 25) + ((19 - 15.7)^2 / 15.7) + ((7 - 9.3)^2 / 9.3)

χ² = 3.1089

The critical value :

df = n - 1 = 4 - 1 = 3

The critical value ;P(χ² at 0.05, df = 3 ) = 7.815

Nitrogenous base DNA consists of four unique nucleotides that each contain one unique nitrogenous base—adenine (A), thymine (T), cytosine (C), or guanine (G).

The specific arrangement of these four bases within the DNA of each organism gives that organism its unique traits; here are the arrangements:

-Adenine is paired with Thymine (think of A for apple and T for tree)

-Cytosine is paired with Guanine (think of C for car and G for garage)

Anaerobic respiration of yeast produces ethanol and carbon dioxide, which can be experimentally tested by determining the rate of CO2 production in a closed system.

Anaerobic respiration is a series of chemical reactions by which certain organisms can produce energy (ATP) in absence of oxygen.

Anaerobic respiration is useful in experimental settings to determine the survival rate of yeast, which can be determined by measuring the concentration of products of this process.

The experimental procedure requires the use of a closed system to determine the rate of change between reactants (glucose) and products (ethanol + carbon dioxide).

In conclusion, Anaerobic respiration can be experimentally tested by determining the rate of CO2 production.
