New Zealand has a population of 4,326,380 and has an area of 103,736 miles squared while Australia has an area of 2,967,909 miles squared and a population of 21,905,140. Explain how New Zealand can have a larger population density than Australia even though it has a smaller total population.

Answers

The reason they have a higher population density is because they have more people on average in a certain area, because New Zealand is smaller they are given less space to live, this means that more people are crammed together, making the density of people within a square mile higher. When you give less square miles, you reduce the amount you have to divide the population by, which makes the density go up.

( In case you wanted the calculations for the density on New Zealand and Australia, it is about 41 to 42 people a square mile in Zealand, and maybe 7 or 8 per square mile in Australia.)

Which region is located between 60-90N and 60-90S?
Mid-Lats
Polar
Tropics
Tropical Rainforest

Answers

Answer:

The correct option is Polar

Explanation:

The polar region/arctic are located/extend from 66.5 degrees N (north) and also S (south) latitude to the north and south poles of the earth. From this, it can be deduced that the polar region is located between 60-90 degrees of N and 60-90 degrees of S.  Polar regions are far from the equator as a result of this and are characterized by very low solar radiation.

Polar or artic region is located between the coordinates 60-90N and 60-90S. The polar regions are extremely far away from the equator, which is situated at 0-degrees latitude.

The correct answer is:

Option B. Polar

The polar region is defined as the region situated 60-degrees north or south of the equator. The solar radiation in the polar region ranges from only 18 hours and 5 hours during winters.

The middle latitudes are situated between 30N and 30S of the equator. It is characterized by moderate sunlight.

Tropics or tropical rainforests are situated near the equator and usually experience a warm climate.

Therefore, option B is correct.

What would happen to the concentrations of
Pyruvate, NADH and intermembrane H+ if the ETC
stopped working?

Answers

Answer:

Stay the Same, Increase, Decrease

Explanation:

Glycolysis produces pyruvate which is functioning normally if only the ETC (electron transport) stopped working because the ETC happens AFTER glycolysis, hence pyruvate is being produced and used at a normal rate (no change). NADH is produced in the cellular respiration stage PRIOR to the ETC so it is being created at a normal (or average) rate, however, it is not being used and split properly (meaning, not enough) in the ETC stage hence it's concentration increases. H+ decreases because it cannot be made if the prior step(s) were not complete.

What would happen to the concentrations of pyruvate, NADH and intermembrane H+ if the ETC stopped working are:

Pyruvate would stay the same and not be affected.that is it would remain the same.NADH would increaseH+ in the intermembrane would decrease.

The concentration of the Pyruvate would not be affected If ETC stopped working and so this will make NADH would increase. Due to the fact that there is no electrons been transported down the chain, so therefore, no H+ would be moved and this in turn would make the concentration of H+ in the intermembrane space to reduce.

Conclusively, we can therefore say that what would happen to the concentrations of pyruvate, NADH and intermembrane H+ if the ETC stopped working are:

Pyruvate would stay the same and not be affected.that is it would remain the same.NADH would increaseH+ in the intermembrane would decrease.

Answers

Answer:

The correct answer would be - GG and gg.

Explanation:

As it is given that all the 1000 offspring having the same allele Gg which is only possible in one condition that is cross between GG and gg because it is a heterozygous condition in the offspring. So there must be both allele present and it can not be heterozygous parents as there would be a different combinations of offspring in that case.

Cell Definition

“A cell is defined as the smallest, basic unit of life that is responsible for all of life’s processes.”

Cells are the structural, functional, and biological units of all living beings. A cell can replicate itself independently. Hence, they are known as the building blocks of life.  

Each cell contains a fluid called the cytoplasm, which is enclosed by a membrane. Also present in the cytoplasm are several biomolecules like proteins, nucleic acids and lipids. Moreover, cellular structures called cell organelles are suspended in the cytoplasm.

Types of Cells.Prokaryotic Cells

Prokaryotic cells have no nucleus. Instead, some prokaryotes such as bacteria have a region within the cell where the genetic material is freely suspended. This region is called the nucleoid.

They all are single-celled microorganisms. Examples include archaea, bacteria, and cyanobacteria.

The cell size ranges from 0.1 to 0.5 µm in diameter.

the hereditary material can either be DNA or RNA.

Prokaryotes reproduce by binary fission, a form of sexual reproduction.

Eukaryotic Cells

Eukaryotic cells are characterised by a true nucleus.

The size of the cells ranges between 10–100 µm in diameter.

This broad category involves plants, fungi, protozoans, and animals.

The plasma membrane is responsible for monitoring the transport of nutrients and electrolytes in and out of the cells. It is also responsible for cell to cell communication.

They reproduce sexually as well as asexually.

There are some contrasting features between plant and animal cells. For eg., the plant cell contains chloroplast, central vacuoles, and other plastids, whereas the animal cells do not.

Functions of Cell:Provides Support and StructureFacilitate Growth MitosisAllows Transport of SubstancesEnergy ProductionAids in ReproductionCell Membrane The cell membrane supports and protects the cell. It controls the movement of substances in and out of the cells. It separates the cell from the external environment. The cell membrane is present in all the cells. The cell membrane is the outer covering of a cell within which all other organelles, such as the cytoplasm and nucleus, are enclosed. It is also referred to as the plasma membrane. By structure, it is a porous membrane (with pores) which permit the movement of selective substances in and out of the cell.  Besides this, the cell membrane also protects the cellular component from damage and leakage. It forms the wall-like structure between two cells as well as between the cell and its surroundings. Plants are immobile, so their cell structures are well-adapted to protect them from external factors. The cell wall helps to reinforce this function.What is Osmosis?

Osmosis is a passive process and happens without any expenditure of energy. It involves the movement of molecules from a region of higher concentration to lower concentration until the concentrations become equal on either side of the membrane.

Any solvent can undergo the process of osmosis including gases and supercritical liquids.

Osmotic Solutions There are three different types of solutions:

An isotonic solution: is one that has the same concentration of solutes both inside and outside the cell.

A hypertonic solution: is one that has a higher solute concentration outside the cell than inside.

A hypotonic solution; is the one that has a higher solute concentration inside the cell than outside.

Effect of Osmosis on Cells

Osmosis affects the cells differently. An animal cell will lyse when placed in a hypotonic solution compared to a plant cell. The plant cell has thick walls and requires more water. The cells will not burst when placed in a hypotonic solution. In fact, a hypotonic solution is ideal for a plant cell.

An animal cell survives only in an isotonic solution. In an isotonic solution, the plant cells are no longer turgid and the leaves of the plant droop.

The osmotic flow can be stopped or reversed, also called reverse osmosis, by exerting an external pressure to the sides of the solute. The minimum pressure required to stop the solvent transfer is called the osmotic pressure

Significance of Osmosis Osmosis influences the transport of nutrients and the release of metabolic waste products.It is responsible for the absorption of water from the soil and conducting it to the upper parts of the plant through the xylem. It stabilizes the internal environment of a living organism by maintaining the balance between water and intercellular fluid levels. It maintains the turgidity of cells. It is a process by which plants maintain their water content despite the constant water loss due to transpiration. This process controls the cell to cell diffusion of water. Osmosis induces cell turgor which regulates the movement of plants and plant parts. Osmosis also controls the dehiscence of fruits and sporangia. Higher osmotic pressure protects the plants against drought injury.

Nucleotides are to ___
as ____
are to proteins.

O nucleic acids; amino acids

O amino acids; polypeptides

O genes; enzymes

O polymers; polypeptides

Answers

Answer:

Your answer is A). Nucleotides make up nucleic acids like DNA and RNA, and a protein is a chain of amino acids.

Nucleotides are to nucleic acids as amino acids are to proteins.

In the given fill-in-the-blanks, we are required to determine and identify which parts correspond with the given words.

Nucleotides are a "nucleoside and a phosphate" combination constituting the monomeric unit of nucleic acids. They have numerous metabolic roles and are also essential for DNA replication and RNA transcription. Amino acids are the building blocks of proteins and are an important component of our bodies. As given above, we can now ascertain that nucleotides and nucleic acids are related while amino acids are to proteins.

With the requirement to join the corresponding 'elements' with each other, we can understand and identify the words and the blanks by determining the constituent of each element. And by doing that, we can safely say that nucleotides make up nucleic acids like amino acids are for proteins. Thus, the correct answer is the first option.

An agricultural biologist was evaluating two newly developed varieties of wheat as potential crops. In an experiment, seedlings were germinated on moist paper towels at 20ºC for 48 hours. Oxygen consumption of the two-day-old seedlings was measured at different temperatures. The data are shown in the graph below. In a second experiment, variety A seedlings at both temperatures were treated with a chemical that prevents NADH from being oxidized to NAD+. Predict the most likely effect of the chemical on metabolism and oxygen consumption of the treated seedlings. Explain your prediction.

Answers

Answer:

The definition is listed in the clarification segment below, and according to the present circumstances.

Explanation:

It undergoes different morphological as well as biochemical modifications mostly during germination. Product contains nutrients and even some hydrolases such as energy, carbohydrates. Owing to the availability of phytic compounds, the seed coat seems to be very durable in nature. Hydrolytic enzymes launch their function by consuming oxygen throughout order to remove this hard coating. In several other processes, including the electron transport system as well as the Kreb process, oxygen also becomes necessary.

The initial phase of germinating seeds requires anaerobic environments where even the enzymes dehydrogenase can function. The subsequent dehydrogenase enzyme brings the electron throughout the electron transport system from either the base to oxygen.  Unless the oxygen frequency is compared with varieties A and B, it can be seen through the analysis that variety B actually absorbed more oxygen. Oxygen intake rates are also depending upon period.The impact of temperature mostly on absorption of oxygen seems to be present. Shift the supply at low temperatures have a low intake of oxygen, while varieties grown over extreme temperatures use much more oxygen. The metabolism of such a seedling is influenced by temperature. Metabolically active young plants display a larger intake of oxygen.

If your not gonna put a HELPFUL ANSWER, please do not answer, thanks.

Answers

Answer:

Any sort of prexisting rock whether sedimentary, igneous, or even metamorphic rock must change under extreme conditions like extreme heat or pressure.

Explanation:

An igneous rock is a rock that has been created via cooling of magma.

A sedimentary rock is formed from sediments, whether they be natural like seashells, or other pieces of older rocks that have worn away. usually formed under pressure.

A metamorphic rock is a rock that's changed, because it was put under extreme pressure or exposed to extreme heat.

Think of the part morphic in the word metamorphic-it literally means that it morphed or that it changed dramatically.

There are two ways for a rock to become metamorphic under extreme pressure or extreme heat. and there are two types of metamorphic rocks, contact metamorphism and regional metamorphism.

Those mean pretty much exactly what they say.
