Answer:

4

Explanation:

carbon atoms only have four valence electrons so they can only bond with 4 other atoms

Answer: Four (4)

Explanation: Carbon has a total of six electrons in its shell but has four (4) electrons in its outermost shell. Electrons found in the outermost shell are called valence electrons. This means that carbon needs four (4) electrons to complete its octet structure that is carbon needs four electrons to attain a stable octet structure of noble gases.

It can be described as "ridge push and slab pull."

Explanation:

The three primary causes for tectonic plate movement are the convection of material in the mantle, gravity and the rotation of the planet. These forces cause each of the seven major plates and numerous other microplates to move independently of the others at a rate of a few centimeters per year.

Gravity plays a crucial role in plate tectonics by influencing the movement and interactions of Earth's tectonic plates. Gravity plays a significant role in plate subduction, which occurs when one tectonic plate sinks beneath another at convergent plate boundaries.

Plate Collision: Gravity acts to compress and deform tectonic plates during plate collisions at convergent boundaries. Mountain ranges, like the Himalayas, are formed when the gravitational force between the plates pulls them together and causes them to bend, fold, and rise.

Isostasy: The Earth's crust is kept in an isostatic equilibrium by gravity. The equilibrium between the upward pull of gravity and the buoyant force of the lithosphere (including tectonic plates) is known as isostasy.

Answer:

mitochondria

Explanation:

Distance travelled by Bobby was 7 meters and the displacement was 5meters.

Distance is defined as the total length of the path travelled by a body from its initial position to final position. Displacement on the other hand is defined as the length of the straight line joining the initial position and the final position of the body.

Here, Bobby travelled from point A to point C via point B which took him to travel more distance. The length of distance from point A to B is 4 meters and from point B to C is 3 meters. So the total distance covered is [tex]4+3[/tex] meters = 7 meters.

While the length of path straight from point A to C is 5 meters. So displacement is 5 meters.

Answer:

layer m-r tilted

Explanation:

The missing step is that Layers M-R were tilted. This conclusion is reached based on principles of original horizontality, superposition and cross-cutting relationships.

Using the principles of original horizontality, superposition, and cross-cutting relationships, we can infer that the missing step in the sequence is option A: Layers M–R were tilted. This is because the layers were initially deposited in a horizontal orientation (the principle of original horizontality). They were then disturbed, causing them to tilt before the igneous intrusion G could cross-cut through layers M–R (principle of cross-cutting relationships). The principle of superposition implies that the lower layers were deposited first, starting with M. Erosion would then occur at surface X (unconformity), allowing for the deposition of the upper layers (H, I, J) in sequence.

Answer:

Hyponatraemia can be described as a situation in which there is a decrease in the sodium concentration of serum. Such condition arises due to excess of water due to which the concentration of the solutes becomes a lot lesser. Hence, it is also called as water intoxication.

The long-distance runner collapsed and died because he had consumed so much water that the water concentration in his body had diluted the concentration of vital minerals such as sodium. The drop-down of the sodium concentration was up to dangerous levels.

Final answer:

Water intoxication, or hyponatremia, occurs when too much water is consumed in a short period, diluting blood sodium levels which can lead to severe health issues and even death. It is particularly risksome for athletes who do not replenish electrolytes lost during intense activity. The condition emphasizes the importance of electrolyte balance along with hydration.

Explanation:

The news clip you are referring to likely discusses a rare but serious condition known as water intoxication or hyponatremia. This condition occurs when someone drinks too much water in a short period, leading to a dilution of sodium in the bloodstream. Our bodies need sodium and other electrolytes at specific concentrations to function properly. When these concentrations drop too low, it can result in symptoms ranging from headaches and nausea to more severe consequences like seizures, coma, and even death. The cells may swell from the excess water, particularly dangerous are the brain cells, which can lead to increased pressure inside the skull and possibly death.

Healthy kidneys can typically excrete up to one liter of excess water per hour, but drinking beyond this capacity overburdens the body's regulatory systems. For athletes or anyone involved in extensive physical activity, it is crucial not only to hydrate but also to replenish electrolytes lost through sweat. Simple water rehydration without electrolyte balance can lead to the dangerous dilution effect described. Thus, the runner in the news clip likely suffered from water intoxication due to excessive water intake without adequate sodium and electrolyte replacement.

Answer:

Endangered species can be described as the species of animals or plants which are at the verge of extinction. Scientists tend to recognize the importance of every species in an ecosystem and make the world aware of the species which might go extinct. Nowadays, governments and citizens of a country pay much more attention to protect the endangered species.

Although, the wolves were a threat to some ecosystems but scientific researches have shown that these organisms can be beneficial in a number of ways. Hence, measures should be taken to protect these species. However, we can introduce species of wolves where the number of preys is more so that the ecosystem can be balanced.

Final answer:

The reintroduction of wolves is a complex issue with various stakeholders having different interests. The effects on ecosystems, like those seen in Yellowstone National Park, are positive, but conflicts with human activities such as ranching and hunting arise. Conservation decisions require balancing ecological benefits, human interests, and the rights of endangered species.

Explanation:

The decision to reintroduce wolves and its impact on humans and the environment is a complex one, not a simple yes or no question. Stakeholders such as environmental activists, cattle ranchers, and hunters all have differing perspectives on the matter. Environmental activists may favor the reintroduction due to the positive ecological effects, such as those observed in Yellowstone National Park, where wolves changed the grazing behaviors of elk, leading to the regrowth of vegetation and improved ecosystem health. Ranchers and hunters, however, could face challenges like livestock predation and changes to hunting grounds.

In addressing the protection of endangered species and undertaking large conservation projects like building dams, it is necessary to recognize the various winners and losers, including both human communities and wildlife. For instance, with dam projects, while the energy produced can benefit societies, the environmental damage and loss of ecosystem services may be irreplaceable. Thinking about biodiversity conservation, we can also consider the effectiveness of purchasing 'green' products, assessing their true impact on promoting sustainable practices.

Furthermore, when a government informs someone of an endangered species on their property, they may experience a range of emotions from pride to anger. They must weigh their development plans against conservation efforts and seek compromises that balance private rights, public interest, and species protection. Lastly, strategies to deal with human-wildlife conflicts and the effects of rewilding initiatives are essential factors in conservation planning.

Answer:

Statement 1: Homologous chromosomes line up at the equator in pairs.

Name of Phase: Metaphase 1

Sequence: 3

Statement 2: The cell replicates its chromosomes

Name of Phase: S-Phase, Interphase

Sequence: 1

Statement 3: Homologous chromosomes separate and move to opposite poles of the cell

Name of Phase: Anaphase 1

Sequence: 4

Statement 4: Spindle forms, DNA coils up in homologous chromosomes come together in a tetrad; crossing over may occur.

Name of Phase: Prophase 1

Sequence: 2

Statement 5: Events occur in reverse order of prophase 1

Name of Phase: Telophase 1

Sequence: 5

Explanation:

Following is a summary of the events of meiosis:

1. Interphase:

Prepares the cell for division. Duplication of DNA, duplication of centrioles occurs and the cell grows in size. At this stage the cell is diploid (2n).

2. Prophase 1:

First stage of Meiosis 1.The centrioles move to the poles of the cell, the nuclear membrane disintegrates, homologous chromosomes pair up (in the form of tetrad), form a chiasmata and then exchange segments of chromosomes with each other. This process is called crossing over.

3. Metaphase 1:

Involves the arrangement of the crossed over, homologous chromosomes on the metaphase plate which is sort of like a web of spindle fibers that originates from the centrioles.

4. Anaphase 1:

The tetrads arranged on the metaphase plate are pulled apart by the spindle fibers. This is the result of tension that build up in the spindle fibers as they grow towards opposite poles.

5. Telophase 1:

The last stage of meiosis 1. Involves the arrival of the chromosomes at the poles, the nuclear membrane starts to form and the chromosomes start decondensing. Telophase 1 yields 2 daughter cells with half the number of chromosomes as that in the parent cell.

Meiosis 2:

Meiosis 2 is exactly similar to mitosis. The only difference is that the haploid cells entering meiosis 2 do not duplicate their DNA. Meiosis 2 just involves the separation of the sister chromatids of homologous chromosomes.
