The sides of the ladder are made of alternating sugar and phosphate molecules. The sugar is deoxyribose. The rungs of the ladder are pairs of 4 types of nitrogen bases. Two of the bases are purines- adenine and guanine.
Normally, how many chromosomes are required to determine the outward expression of a trait?a homologous paironly oneany twotwo pairs
Answer:
A homologous pair
Explanation:
In determining the expression trait of humans, this is based on the homologous chromosomes. This in turn comprised of alleles otherwise known as homologous alleles. The homologous loci are thereby located in these alleles which served as the formation of traits when combined.
Hence, normally, A HOMOLOGOUS PAIR is required to determine the outward expression of a trait?

The first phase of mitosis, in which chromosomes condense, becoming visible, the nuclear membrane dissolves, the centrosomes move to opposite ends of the nucleus, and spindle fibers form
Prophase is described as the first stage of mitosis, during which the cell begins to position itself to separate the chromatids and divide. During prophase, the nuclear envelope and nucleolus dissolve and chromosomes condense.
What is Mitosis?Mitosis is defined as the end of the cell cycle in which duplicated chromosomes separate into two new nuclei giving rise to genetically identical cells in which the total number of chromosomes remains the same. That's why mitosis is also called parity division.
Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase where the prophase is the first visible stage in karyokinesis. During prophase, the nuclear envelope and nucleolus dissolve and chromosomes condense.
Thus, Prophase is described as the first stage of mitosis, during which the cell begins to position itself to separate the chromatids and divide.

Identify the type of air (warm or cool) that regions from southern California east to Florida are currently experiencing and explain why.
Answer:
Jet streams, warmer air
Explanation:
my teacher mrs S has a study guide on this
Jet Streams
About 10 km above Earth’s surface are bands of high-speed winds called jet streams.
Meteorologists use the location of some of the jet streams as an aid in weather forecasting.
Jet streams generally blow west to east.
Jet streams form at the boundary of adjacent air masses with significant differences in temperature (polar region vs. Equator).
Jet streams move weather systems across the U.S.
Jet streams have a meandering shape.
warm air is flowing on the bottom and cold air on the top
Compare and contrast the three types of muscle tissue. skeletal muscle, cardiac muscle, and smooth muscle.
Answer:
While skeletal muscles are arranged in regular, parallel bundles, cardiac muscle connects at branching, irregular angles, called intercalated discs. Striated muscle contracts and relaxes in short, intense bursts, whereas smooth muscle sustains longer or even near-permanent contractions.

The diagram below shows a portion of the concept map for the Rock Cycle:
(shown below)
Which of these would best fit in the missing part of the cycle?
Magma
Lava
Sedimentary rocks
Sediments
Answer:
Sedimentary Rock
Explanation:
The option that would best fit in the missing part of the rock cycle is the sedimentary rocks. Thus, the correct option for this question is C.
What is the Rock cycle?The rock cycle may be defined as a series of processes that a rock of the earth's crust can undergo in its lifespan. These processes significantly illustrate the transformation of a rock's state from one form to another.
The conversion of metamorphic to sedimentary rock is mediated by the process of weathering. Metamorphic rocks will be exposed to weathering processes and may break down into sediment. These sediments could then be compressed to form sedimentary rocks, which would start the entire cycle anew.
Therefore, the option that would best fit the missing part of the rock cycle is the sedimentary rocks. Thus, the correct option for this question is C.

Glaciers are masses of ice that move that move slowly on land. Which of these features was most likely formed by a glacier?
f. a wide valley
g. a deep ocean
h. a lava flow
j. a mountain range
Answer:
A deep ocean
uhhh yeah I just have to type this part so it send anyways hope this helps!
The feature that was most likely formed by a glacier is a deep ocean. The correct option is g.
What are glaciers?A glacier is a vast, perpetual accumulation of crystalline ice, snow, rock, silt, and sometimes liquid water that forms on land and travels down a slope due to its own weight and gravity.
Melting glaciers contribute to rising sea levels, which increases coastal erosion and storm surge as warming air and ocean temperatures produce more frequent and intense coastal storms such as hurricanes and typhoons.
Surface wind-driven currents cause upwelling currents, which combine with landforms to form deepwater currents. Currents can also be caused by temperature (thermo) and salinity (haline) variations in water masses, a process known as thermohaline circulation.
Therefore, the correct option is g. a deep ocean.

What is the best way to describe our current understanding of the one-gene/one-polypeptide hypothesis
Answer:
It applies to prokaryotes but not to eukaryotes.
Explanation:
one-gene/one-polypeptide hypothesis is based on the idea that there is a structurally complex gene whereby each gene encodes a single polypeptide, that either operates on its own or under a relatively more complex protein.
However, based on the existing findings and research, the one-gene/one-polypeptide hypothesis "applies to prokaryotes but not to eukaryotes."
This is because one gene/one-polypeptide cannot be used to explain different spliced versions found in several eukaryote organisms

9:3:3:1
1:1:1:1
1:3:3:9
9:1:3:3
Answer:1339
Explanation:
9:3:3:1 is the phenotypic ratio, a phenotypic ratio is a numerical comparison of two phenotypes that demonstrates how frequently the occurrence of one trait corresponds with another.
What is phenotypic ratio?The phenotypic ratio produced from a test cross is used by researchers to determine the gene expression for generations of an organism.
Researchers use the phenotypic ratio obtained from a test cross to determine gene expression for subsequent generations of an organism. A test cross is a genetics method for determining the genotypes and traits of an organism's offspring.
