Urey and miller cooked a "primordial soup" with Hadean gases, water snd electricity to make _____,_____,_____ and_____

Answers

Answer:

Urey and miller cooked a "primordial soup" with Hadean gases, water and electricity to make glucose, acetic acid, amino acids and lipids.

Explanation:

In the Miller-Urey experiment, the aim was to reproduce the conditions of the earth before the existence of life, with the objective of demonstrating the formation of organic matter from inorganic molecules.

The scientists took water and gases present in the Hadean eon —previous to the existence of life— such as methane, carbon dioxide, hydrogen, nitrogen and even ammonia, the primordial soup. This mixture was subjected to electrical discharges, inside closed containers.

The results were some organic molecules, including glucose, acetic acid, amino acids and fatty acids. In these results the presence of macromolecules, such as proteins or nucleic acids, is not appreciated, however it was a significant contribution to the knowledge of the origin of life on earth.

Answers

Spring and Neap rides occur twice a month

Spring and neap tides occurs twice a month.

What is the difference between spring and neap tides?

A neap tide refers to a period of moderate tides when the sun and moon are at right angles to each other. A spring tide is a common historical term that has nothing to do with the season of spring.

In the period between the two spring tides, the moon faces the Earth at a right angle to the sun. When this happens, the pull of the sun and the moon are weak. This causes tides that are lower than usual. These tides are known as neap tides.

Spring tides have higher high tides and lower low tides whereas neap tides have lower high tides and higher low tides. Hence, the range (difference in water level between high and low tide) is much larger in a spring tide than in a low tide.

what natural causes destroy ponds​

Answers

Answer:

invasive species

Answer:

In the explanation. :)

Explanation:

The water in a pond must remain clean if it is to provide a healthy environment for the organisms (animals and plants) living in it. The natural waste from the living and dead organisms is ‘recycled’ by special tiny organisms called bacteria. Plenty of oxygen is needed for the bacteria to ‘break down’ the waste. The pond can take care of its own waste – it’s people who cause pollution!

The most noticeable kind of pollution is the dumping of rubbish – anything from old cars and drinks cans to bikes and bottles have been found cluttering up ponds. This not only makes the environment look so unsightly but it may also destroy pond-life.

Perhaps the most serious threat to ponds is chemical pollution as a result of modern farming methods. Over the years fields have been sprayed with pesticides to rid the crops of pests. However, rain often washes the excess chemicals off the crops into nearby ponds, streams or rivers, poisoning some of the animals living there. Fortunately, these poisonous chemicals are not used so freely now and, hopefully, this problem will gradually be reduced.

Another, equally serious, problem connected with agriculture is the use of artificial fertilizers. Powdery chemical fertilizers, containing nitrates, are put on the crops to help their growth but they can also be washed off by rain into nearby ponds. They do not poison the wildlife but the rich supply of nitrogen causes the water plants, especially algae, to grow very quickly. The plants use up so much oxygen during the night and during decaying processes that there is none left for the other pond-life. The growth also prevents sunlight reaching the organisms below. Eventually, all the algae die leaving a smelly, decaying mass. The case of excess nitrates in water is called eutrophication.

Hope this helps. Have a great day!

summarize how small, nonpolar molecules enter and leave the cell (and why).

Answers

Answer:

Small, nonpolar molecules (ex: oxygen and carbon dioxide) can pass through the lipid bilayer and do so by squeezing through the phospholipid bilayers. They don't need proteins for transport and can diffuse across quickly.

Explanation:

The channel proteins act like doors through the cell membrane.

They allow large polar molecules to move in and out of the cell.

The process is called passive diffusion or passive transport, because it does not need energy.

Sometimes the protein changes shape to help the polar molecules move through the channel.

It often uses a gated pore mechanism, in which the channel is never completely open.

A fish is swimming around the 720-meter perimeter of her pond. If she swims 10 laps in 120 minutes, what is her average speed in m/min?

Answers

Answer:

The average speed of the fish is:

60 m/min

Explanation:

You must take into account that the fish swims 10 laps, so you must multiply the perimeter by 10 to obtain the total meters swam:

720 m * 10 = 7200 meters.

Now, you just must divide the total meters swam by the number of minutes that the fish took to do this, so:

7200 m / 120 min = 60 m/min

Remember, ever you do an exercise like this, you must check the units, I mean, the units that the exercise wants to be the same you use, in this case, the average speed of the fish is 60 m/min.

Answer is option d 8,5,14 yw jit good luck

Carpal bones are bones of the human hand and consists of eight wrist bones which connects hand to the forearm. The Wrist is known as carpus and is the sole cluster of bones.  

These bones don't belong to fingers and are labeled in alphabetical order from A to H. The metacarpals are thin and long bones that are connected by carpal bones in the wrist and the phalanges.  They all are made of a base, shaft, and head. The first metacarpal is the thickest and shortest of them all. The phalanges are tubular ones in the thumb and the fingers found in the foot.They consist of proximal, distal, and middle phalanx. hence fourteen in total.

Hence the option D is correct that is 8 carpals, 5 metacarpals, and 14 phalanges.

Which two species are most closely related?

Answers

Answer:

Two species (B & C) are more closely related to one another than either one is to a third species (A) if, and only if, they share a more recent common ancestor with one another (at Time 2) than they do with the third species (at Time 1).

Explanation:

B and C species are closely related in this phylogenetic tree. A diagram that shows the evolutionary relationships between different species or groups of animals is called a phylogenetic tree.

By showing the branching points where species diverged from a common ancestor, it exemplifies the shared ancestry and evolutionary history of species. The arrangement of species on branches that have a recent common ancestor reflects the degree of relatedness between organisms.

Closely related species tend to cluster together on such branches. Phylogenetic trees are constructed based on similarities and differences in genetic structure, physical characteristics, or other traits observed in different animals. They are important tools in the discipline of evolutionary biology to study patterns of variation and the development of life on Earth.

describe one of the interactions between the four major earth systems​

Answers

Answer:

Explanation: Everything in Earth's system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called "spheres." Specifically, they are the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air).

The water cycle is one of the interactions that significantly occurs between all four major earth systems. These systems are also known as spheres.

What are the four major earth systems?

The four major earth systems include the lithosphere which deals with the land, the hydrosphere which linked all sorts of water on the earth's surface, the atmosphere which is associated with the presence of air, and the biosphere where life exists and living organisms live in order to play their functional role.

According to the context of this question, each and every biogeochemical cycle like the water cycle, carbon cycle, etc. process with the successful interaction of all these earth systems.

This is because these cycles include all kinds of products that are derived directly or indirectly from these spheres. For example, the gaseous form of water is present in the atmosphere while its liquid state is present in biospheres.

Therefore, the water cycle is one of the interactions that significantly occurs between all four major earth systems.

Erwin Chargaff is considered one of the pioneering scientists in the field of molecular biology. In one of his studies, Chargaff observed that a sample of human DNA contained approximately 30% adenine (A). Based on DNA structure, what are the expected percentages of the other nitrogenous bases in the sample?

Answers

A.

10% thymine, 40% cytosine

B.

20% thymine, 30% cytosine

C.

30% thymine, 20% cytosine

D.

40% thymine, 10% cytosine#

Answer:

30% thymine, 20% cytosine

Explanation:

In  a typical DNA double helix pyrimidine; Cytosine and thymine always pair with Purine ;Adenine and Guanine. This pairing ensure that the double helix of DNA is maintained  by the presence of Hydrogen between these organic bases.

For correct pairing all adenine must pair with thymine,and all Cytosine with guanine.Therefore for this to occur if 30 % of adenine is present,the  composition and number of thymine(30%) must be available.If this percentage is not available the pairing  will not occur.

Like wise  20% Cytosine must be present because ,then same amount of  Guanine molecule 20% in the DNA molecule. must be present Thus Guanine percentage is 20%.

This give a total of 100(60+40)

This based on the Erwin Chargaff  stoichiometric ratio  of 1:1 .This  states that the percentage of adenine =thymine,and that of Guanine=Cytosine,in the DNA of living cells should be equal. Thus; [A]+[G]=[C]+[T]=1:1

What is the climate?

Weather is affected by various factors, such as temperature, humidity, etc., and that is not permanent for years, but it is temporary because when there is a rainy day, the weather condition of that place is more cold, while in a place where there is a high temperature, the weather becomes dry for that region. Climate is a weather condition that lasts for long periods of time, such as 20 or 30 years, and depending upon the climate, different ecosystems are considered.
