Normally, how many chromosomes are required to determine the outward expression of a trait?a homologous paironly oneany twotwo pairs

Answers

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?

Which types of cells have genetic material that is contained in a nucleus

Answers

Answer:

There are two basic types of cells, prokaryotic cells and eukaryotic cells. The main difference between eukaryotic and prokaryotic cells is that eukaryotic cells have a nucleus. The nucleus is where cells store their DNA, which is the genetic material. The nucleus is surrounded by a membrane.

Eukaryotic cells have a nucleus which is where they store their genetic material and a prokaryotic cells doesn’t have a nucleus :)

Identify the type of air (warm or cool) that regions from southern California east to Florida are currently experiencing and explain why. ​

Answers

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

cellular respiration ..hope this helps!

Answer:

3.) Cellular respiration

Explanation:

During cellular respiration, the energy stored in glucose is transferred to ATP.

During this, glucose, in the presence of oxygen, is converted into carbon dioxide and water.

glucose + oxygen → carbon dioxide + water.

During this process, the energy stored in glucose is transferred to ATP.

Answers

Answer:

Phospholipid bilayer: layers that limit what enters or leaves the cell​

Fibrous Protein: Receptors for the cell

Pore Protein: Transports ions

Glycoprotein: Used for identification of cells

Channel protein: Forms a pone for movement of water

Explanation:

Phospholipid bilayer is consist of two layers, interior layer is hydrophilic (water loving) and exterior layer is hydrophobic (water hating). This layer functions as a selectively permeable membrane and allows only required materials into the cell.

Fibrous Protein is one of the type of protein and act as cell surface receptor. for example: collagen and fibronectin act as cell surface.

Pore Protein are beta barrel proteins that creates pores for the ions to diffuse across the cell.

Glycoproteins are located on the surface of the lipid bilayer and act in cell-cell recognition and bind to the cell after recognizing or identifying properly for further procedure.

A channel protein is a channel in he cell membrane that is made up of amino acids. It forms a hydrophilic gateway for water and small, polar ions.

Hence, the correct answer is:

Phospholipid bilayer: layers that limit what enters or leaves the cell​

Fibrous Protein: Receptors for the cell

Pore Protein: Transports ions

Glycoprotein: Used for identification of cells

Channel protein: Forms a pone for movement of water

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

Answers

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.

Which of these would best fit in the missing part of the cycle?

Magma

Sedimentary rocks

Sediments

Answers

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.

What is the best way to describe our current understanding of the one-gene/one-polypeptide hypothesis

Answers

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

Why does the thermosphere have the highest temperature of alle
atmosphere layers?
O A. It has the least gas particles.
B. It is closest to the sun.
C. It contains the ozone layer.
D. It is the thinnest layer.

Answers

Answer: B.

Explanation:

The thermosphere is most directly affected by the Sun’s radiation.

The thermosphere have the highest temperature of alle atmosphere layers It is closest to the sun.

What is Thermosphere?

A portion of the Earth's atmosphere known as the thermosphere is situated precisely above the mesosphere and under the exosphere. It stretches from around 90 km (56 miles) to 500–1,000 km above the surface of our planet.

In the lower thermosphere temperatures rise dramatically before leveling off and remaining rather constant as altitude rises above that point. The thermosphere's temperature is significantly influenced by solar activity.

In general, the thermosphere is around 200° C hotter during the day than at night, and about 500° C  hotter during periods of high solar activity.

Therefore, The thermosphere have the highest temperature of alle atmosphere layers It is closest to the sun.
