Answer:

The highest level of organization for living things is the biosphere; it encompasses all other levels. The biological levels of organization of living things arranged from the simplest to most complex are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.

Answer:

The average speed of the fish is:

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:

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

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:

Ribosome

Explanation:

The entire process is called gene expression. In translation, messenger RNA (mRNA) is decoded in a ribosome, outside the nucleus, to produce a specific amino acid chain, or polypeptide. The polypeptide later folds into an active protein and performs its functions in the cell.

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

Answer:

Deer populations increase through births or when new animals move into the area (immigration). Deer populations decrease through deaths or when animals leave the area or disperse (emigration). Population change = (birth + immigration) - (death + emigration).

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.

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.

Holmes proposed that the continents, which “floated” on the Earth's mantle, moved with the convection flow of the magma (hot semifluid below the Earth's crust). The mechanism of continental drift is like the flow of branches floating in the moving waters of rivers, as shown in Figure 3-11.4.

Answer: D. Because enzymes are protiens but they are produced of amino acids

Explanation:

Enzymes are composed of proteins, that assist our bodies' chemical reactions to move forward more quickly. For several processes, including digestion and liver function, enzymes are crucial.

Health issues might result from having too much or too little of a specific enzyme. Healthcare professionals can also use the enzymes in our blood to look for injuries and illnesses.

Among countless other functions, they are crucial for breathing, food digestion, and the health of the muscles and nerves. Numerous enzymes can be found inside each cell of the human body. Each cell's internal chemical operations can be aided by enzymes.

Digestion enzymes are produced by your pancreas, small intestine, and stomach. The "powerhouse" of digestion's enzymes is actually the pancreas. The most significant digestive enzymes are produced by it.

Therefore,  in the human body, enzymes aid in accelerating chemical reactions, hence option D is correct.

It just wouldn't add up right, none of the other's DNA matches to the suspect, leaving the suspect as not guilty but inisent and doesn't lead or match that suspect to in any way the killer.

Answer:

The correct answer is: C. Active Transport.

Explanation:

Because Na+ and K+ are ions, which makes them charged molecules, they can only diffuse through the cell membrane when using specialized protein channels. This is called facilitated diffusion and is a form of passive transport because sodium and potassium move following their gradients, which are made of the difference in concentration between the inside of the cell and the outside of the cell. For example, potassium is highly concentrated inside the cell and poorly concentrated outside the cell, so potassium diffuses from the inside to the outside to even the concentrations.

But the question asks in which process Na+ and K+ move in and out of the cell SIMULTANEOUSLY, so the answer is actually active transport. Active transport is the opposite of passive transport. While passive transport occurs naturally and doesn't need ATP (energy) to happen, active transport needs ATP because it moves molecules AGAINST their gradient. One of the most famous and important structures involved in active transport is the Na+/K+ pump, which consists of a specialized protein using energy to enter 2 potassium ions and take out 3 sodium ions at the same time. This Na+/K+ is fundamental to maintain the gradients, which are important for the correct functioning of many cells.

Answer:

Eukaryotes are organisms whose cells have a nucleus enclosed within a nuclear envelope. Eukaryotes belong to the domain Eukaryota or Eukarya; their name comes from the Greek εὖ and κάρυον. The domain Eukaryota makes up one of the domains of life in the three-domain system; the two other domains are Bacteria and Archaea. Eukaryotes represent a tiny minority of the number of living organisms; however, due to their generally much larger size, their collective worldwide biomass is estimated to be about equal to that of prokaryotes. Eukaryotes evolved approximately 1.6–2.1 billion years ago, during the Proterozoic eon.

Explanation:

Answer:

The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. ... The nucleus is only one of many membrane-bound organelles in eukaryotes. Prokaryotes, on the other hand, have no membrane-bound organelles.
