Division of labour is found in Humans.

____________________________

The other options aren't correct because they are single celled living organisms and they have to perform all work and life processes by that single cell, but in case of humans there are millions of cells having different functions to perform hence the work is distributed and shows division of labour .

Answer:

The answer is mitochondria that the difference between the prokaryotes and eukaryotes

Explanation:

Answer:

a) the autotrophs produce their own energy in their system and synthesize surrounding energy, which allows for the flow of energy as they are the primary producers at the bottom of the food web shown in figure 1 who transfer and facilitate their energy when they are consumed by the organisms in higher levels. This facilitation of energy continues where the population of these autotrophs is stable and the cycle of consumption and synthesis of energy from one trophic level to another and there is a diverse amount of energy distributed in the ecosystem. The leopard and Elephant seals have a similar food preference which may cause competition for resources in the ecosystem between the two more than that of the crabeater seal as they rely solely on krill in the ecosystem to survive. If there was more competition for the krill or a decrease in population, their population is sure to suffer as well.

b) The year is independent of the number of species in the data graphed. This variable affects the biodiversity in the food web where we witness the number of species (hundreds) likely to witness an increase over time when krill are harvested and a decrease in the number of species without krill harvesting. This, in turn, may prove that krill is a keystone species crucial in the food web and ecosystem where the antarctic krill population's presence will influence the number of species as well.

c) The changes in species richness with krill harvesting, as per mentioned, will show an increase in species number as the krill's energy is transferred throughout the ecosystem by consumption, as implied in the food web. The changes in species richness with a lack of krill harvesting, or some organisms unable to consume the energy of the krill, was shown to have a decrease in species # over the years. This will affect the long term structure of the ecosystem as the organisms who rely on krill and even those in the trophic levels which rely on species who consume krill will drop dramatically, and the lowering of the number of organisms in a keystone species will cause a decrease in speciation of the ecosystem (possibly quite rapidly due to the dependence we witness on it) as well as a disruption in the energy flow.

d) we can affirm that the krill are in fact not a foundation species, but a keystone species as they show no specific traits of facilitating the populations of the species in the ecosystem, and don't appear to benefit other species in the ways foundation species do (ie. they are autotrophs and cannot provide shelter for other species, but we can also say that they are the sole energy producers for the crabeater seals, which can be a trait of a foundation species)- instead exhibiting the traits of a keystone species as they produce an abundance of energy in the ecosystem and the removal of them (as shown in figure 2), causes a population decrease all around.

Explanation:

ur welcome i just did this myself so pls paraphrase as much as u can also like a bit of an explanation its kinda obvious from the chart that they all rely on the krill and stuff so removing it (or not harvesting or something) would be bad. again pls paraphrase as much as u can and good luck

Answer:

Predatory.

Explanation:

This is because the tree brown snakes feed on birds while the bats feed on the lizards.

This is so that the bats can eat lizards while the tree brown snakes can eat birds. The brown tree snake bites and grips its victim to paralyze it.

The predators of the brown tree snake are not widely known. According to some research, monitor lizards, feral pigs, and cats prey on brown tree snakes, and other.

Investigations have revealed that the species is also vulnerable to red-bellied black snakes and cane toads.

The snake encircles its victim's body with its own and begins to chew, allowing its teeth with grooves to release venom into the area.

Since mammals are less susceptible to the venom's effects than other animals, it is considered to be rather moderate.

Therefore, predatory  interaction is there between the brown tree snakes and the birds, lizards, and bats.

Answer:

Reaction 1

Explanation:

Reaction 1 would be the most suitable in this case. This is so because in reference to the question you are wanting to keep the food warm over long periods. So in reference to the data in the chart reaction 1 continues to heat up over long periods of time. However, with the other reactions (2, 3, 4) temperatures vary and some even decrease constantly. Therefore showing that the other reactions are invalid to help reach your goal referencing back to the question.

Answer: This can be explained by the fact that whales share a more recent common ancestry with humans (Figure 4) than they do with sharks. We predict that their closer relationship means that they share more features in common, and the evidence supports this prediction.

Explanation:

Answer:

Whales and humans have similar ancestors. Their closer partnership implies that they have much in common.

Explanation:

Answer: 43. Erosion breaks rocks down further and then moves them. Forces like wind and water move the rock pieces. They mix with matter like sand to become sediment. Weathering and erosion help shape Earth's surface. 44. After compaction and cementation the sedimentary sequence has changed into a sedimentary rock. Sedimentary rocks like sandstone, shale and limestone differ from other rocks in that they: 1. Are formed from layers of sediment built up over many years. Clastic sedimentary rocks are made up of pieces (clasts) of pre-existing rocks. Pieces of rock are loosened by weathering, then transported to some basin or depression where sediment is trapped. If the sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock. 45. metamorphic rock. 46.  igneous or sedimentary rock. 47. Similarly, liquid magma also turns into a solid — a rock — when it is cooled. Any rock that forms from the cooling of magma is an igneous rock. Magma that cools quickly forms one kind of igneous rock, and magma that cools slowly forms another kind.

Answer:

Sources of nitrogen from human activities, such as electric power generation, industry, transportation and agriculture, can upset the natural balance of nitrogen in the environment. When fossil fuels are burned, they release nitrogen oxides into the atmosphere, which contribute to the formation of smog and acid rain.

Answer:

Krebs Cycle

Krebs's cycle releases the most CO2 as a wasteproduct

The atmospheric Carbon dioxide is released during the citric acid cycle (Krebs cycle) of the cellular respiration, which is utilized later. Thus, the correct option is A.

Cellular respiration is the process of oxidation of the sugar (glucose) to produce ATP (energy) in the mitochondria of cell. This process is essential as cell requires energy to perform the basic functions of the body.

Cellular respiration is divided into four main phases which include:

1. Glycolysis: The most critical pathway in carbohydrate metabolism

2. Pyruvate Oxidation

3. The Krebs Cycle

4. Electron Transport and Oxidative Phosphorylation

The Krebs cycle also known as Citric acid cycle includes the release of carbon dioxide which is then used in the electron transport chain and in the formation and processing of other important biomolecules in cell.

Therefore, the correct option is A.

Explanation:

Answer: 1) Glucose

2) 36

3) Heat

Explanation: Cellular respiration is a metabolic process that every living organism undergo. It is the process by which energy is obtained by living cells. In the process of celluar respiration, energy-storing food molecule called Glucose is broken down in the presence of oxygen in order to release its energy and convert it to a usable form by the cell called ATP.

Celluar respiration occurs in three distinct stages in eukaryotes viz: Glycolysis Kreb's cycle and Oxidative phosphorylation. In Glycolysis, which occurs in the cytoplasm, glucose is broken down in a series of enzymatic reaction to yield Pyruvate and releasing a net gain of 2 ATP molecules. In Kreb's cycle, which occurs in the mitochondrion, produces carbondioxide in a two-cycled reaction involving Pyruvate. 2 ATPs are also produced in this stage.

Lastly, in Oxidative phosphorylation also occuring in the mitochondrion, electrons are passed through electron acceptors to create a pump that generates the synthesis of 32 ATP molecules. In general, the three stages yield a total of 36ATP molecules from one molecule of GLUCOSE.

The rest of the energy from the oxidation of glucose is lost as heat energy, which is responsible for the warming effect we feel. braibnliest??
