Group of cells construct the organs of human body which helps our body to function properly.

Explanation:

All living things are made up of cells. Human body is constituted of approximately 200 cells. Not every cell functions equally. Different cells function differently. However, the cells which has the same work to do they combine to form tissues, and groups of cell constructs human organs like heart, lungs etc. which functions together to control the body.

So it can be said that though not directly but cells are indirectly dependent on each other to perform body function.  

Answer:

The model shows that some cells make substances such as proteins for other cells to use and support their functions. So, the model shows that each particular type of cell relies on other cells to support all the functions in the human body.

Answer:

If you have 2 dominant alleles, the gene will be dominant, if you have 2 recessive alleles, the gene will be recessive. But if you have 1 recessive and 1 dominant, the Dominant allele will mask the recessive one.

Explanation:

Final answer:

If a gene has only one allele, it can produce one specific trait in an individual organism. However, within a population, multiple alleles for the same gene can exist, allowing for a range of traits to be expressed among the individuals in that population. The ABO blood type system in humans is an example of multiple alleles influencing various traits.

Explanation:

If a gene has only one allele, it can typically produce only one trait in an individual organism. This is because an allele is a specific version of a gene, and without an alternative allele to combine with, there is no variation at that gene locus in the individual's genotype. However, at a population level, multiple alleles may exist for the same gene, giving rise to various combinations of two alleles and hence multiple traits within the population.

An example of this phenomenon is the ABO blood type system in humans, where there are three alleles (IA, IB, and i) that can combine in different ways. These combinations result in the A, B, AB, or O blood types, showcasing how multiple alleles contribute to genetic diversity.

Still, it's important to note that while an individual organism with a single allele for a gene can typically only express one trait, the presence of multiple alleles at the population level allows for the range of observable traits (phenotypes) to expand beyond that single manifestation.

Answer:

A reaction that joins the nuclei of two atoms into one  

Explanation:

Think of the words "nuclear fusion".

Nuclear = "relating to a nucleus"

Fusion = "joining"

So, nuclear fusion is the joining of two nuclei into one.

A and B are wrong, because chemical reactions involve electrons.

D is wrong, because the splitting of a nucleus is fission.

Final answer:

Nuclear fusion is the combination of light atomic nuclei to form a heavier nucleus, releasing energy, and it is the fundamental process that fuels stars.

Explanation:

Nuclear fusion is best described by option : a reaction that joins the nuclei of two atoms into one. This process involves two or more light atomic nuclei colliding at high speed and combining to form a heavier nucleus. Nuclear fusion releases energy when these light nuclei fuse to form medium-mass nuclei; this is the same process that powers stars like our Sun. The simplest example of this is the fusion of hydrogen isotopes to form helium in the proton-proton cycle, which happens at the extreme temperatures and pressures found in the core of stars.

Answer:

The girl is correct because her father only went the distance of the ladder, whereas she went to the extension of two flights of stairs.

Explanation:

The work done by the girl and her father is the same. The discrepancy arises from the difference in perceived effort, not actual work done. In physics, work done against gravity for the same weight over the same vertical distance is equal, regardless of the path taken.

The question asked pertains to the concept of work in physics. According to the definition of work in physics, work is equal to the force applied to an object times the distance the object is moved in the direction of the force. The force in this scenario is the same, as the same weight box is being lifted. The distance is also the same (the vertical distance from the ground to the attic). Therefore, regardless of the path taken (flight of stairs or directly using a ladder), the work done is the same.

It might seem that more effort is required to carry the box up the stairs due to the longer path, however, this is likely due to the additional force required to fight against gravity while taking the longer route, but this doesn't constitute to additional work done in terms of physics. Work Done Against Gravity is the significant concept here. The energy changed from one form to another to overcome gravity remains the same in both cases

Answer:

The atomic mass of silver is 107.86 amu

Explanation:

The atomic mass is calculated by formula

Atomic mass = (Mass of first isotope x Abundance of first isotope) + (Mass of Second isotope x Abundance of second isotope)

In case of silver, the formula will be as

Atomic mass = (Mass of Ag-107 x Abundance Ag-107) + (Mass of Ag-109 x Abundance Ag-109)

Mass of Ag- 107 = 106.9

Mass of Ag- 109 = 108.9

Abundance of Ag-107 = 51.82/100 = 0.5182

Abundance of Ag-109 = 48.18/100 = 0.4818

Putting these values in the formula

Atomic mass of silver = (106.9 x 0.5812) + (108.9 x 0.4818) = 107.86 amu

To calculate the average atomic mass of silver, the masses of its isotopes are multiplied by their relative abundances and summed up, resulting in an atomic mass of 107.841428 amu.

The average atomic mass of an element can be calculated by taking the weighted average of the masses of its naturally occurring isotopes, based on their relative abundances. For silver, we have two isotopes: Ag-107 with a mass of 106.9 amu and an abundance of 51.82%, and Ag-109 with a mass of 108.9 amu and an abundance of 48.18%. To find the atomic mass of silver, we perform the following calculation:

Atomic mass = (Percentage abundance of Ag-107 × Mass of Ag-107) + (Percentage abundance of Ag-109 × Mass of Ag-109)

Atomic mass = (0.5182 × 106.9 amu) + (0.4818 × 108.9 amu)

Atomic mass = 55.359866 amu + 52.481562 amu

Atomic mass = 107.841428 amu

Therefore, the average atomic mass of silver is 107.841428 amu.

Answer:

Explanation:

A, B, and C, are all observing the situations, while D states the deer walked down the path earlier because of the tracks, this is hardly obersavable, and you would have to infere the deer took the path early.

'Deer walked down the path earlier because of the prints in the mud' is an inference, not an observation, as it is a conclusion made based on the observed deer prints. The correct option is D.

The answer to the question which statement is an inference rather than an observation is option D: 'Deer walked down the path earlier because of the prints in the mud.'

An observation refers to something that one directly sees, hears, or experiences, while an inference is a conclusion or assumption drawn from those observations. Options A, B and C are observations as they directly describe actions that are immediate and visible.

Option D, on the other hand, makes a prediction or inference about past events (deer walking) based on current observations (prints in the mud).

The hematic system, or circulatory system, is crucial in transporting substances and distributing blood to all parts of the body. It enables nutrient and oxygen delivery, waste removal, defense mechanism operation, and helps in maintaining the body temperature and acid-base balance. The system also influences both voluntary and involuntary motions.

The function of the hematic system, also known as the circulatory system, primarily involves transporting substances in the body and distributing blood throughout the body. It reaches almost every cell, tissue, organ, and system in the body. The circulatory system is responsible for the transportation of materials, such as nutrients and oxygen, to different parts of the body, allowing our cells to function properly. Furthermore, it plays a critical role in our body's defense mechanism, distributing white blood cells and immune system antibodies to maintain our health. It also contributes to controlling body temperature and maintaining the acid-base balance.

Moreover, the circulatory system works closely with other body systems. For instance, it moves in conjunction with our body muscles, enabling us to perform both voluntary and involuntary motions. It also provides the physical site for the exchange of gases, nutrients, and other substances with body cells, ensuring effective metabolism and cellular processes.

Answer:

The sphere: volume is about 113.1

The cylinder: Volume is about 11309.73

Explanation:

This is done by using the formula for the volume of a sphere ( v=4/3 pi r^3) and the formula for the volume of a cylinder (v=pi r^2 h). You plug in things such as radius, height, and pi or 3.14 into a calculator.

The volume of the spherical cell is 36π cubic units, while the cylindrical cell's volume is 3600π cubic units. The volume of a cell has a significant impact on its function and efficiency.

The question is asking to determine the volume of two different cells: a spherical cell and a cylindrical cell, both have a diameter of 6 units, with the cylindrical cell having a height of 400 units.

In geometry, volume describes the amount of space an object occupies. The formula to calculate the volume of a sphere is V = 4/3πr³ and for a cylinder, it is V = πr²h. Here, r stands for radius and h stands for height.

In the case of the sphere, since the diameter is given as 6 units, the radius would be 3 units. So, the volume of sphere would be V = 4/3*π*3³ = 36π cubic units.

For the cylindrical cell, the diameter is also 6 units, making the radius 3 units. The height is given as 400 units. The volume of the cylinder would be V = π*3²*400 = 3600π cubic units.

These calculations can give you the volume of the cell shapes, and further helps you understand how size and shape can affect a cell's function and efficiency.

Answer:

The correct choices are A,C AND E.

Explanation:

The formation of clouds occurs when the warm air cools and the temperature drops to dew point. The dew point can be describes as the temperature which occurs when the air becomes saturated into water vapour. The air becomes cooler and when humidity of 100% is acquired, water droplets form which lead to the formation of clouds. The formation of clouds has always been  known to occur when temperature drops to the dew point.

As the warm air cools, it also results in forming tiny water droplets on the grass especially in the morning times. This most likely happens when the day has been warm followed by a cold night. The water droplets formed on the grass are known as dew.

When air cools to the dew point, the moisture it holds condenses forming clouds and dew on grass surfaces. The air's humidity does not increase, rather, the relative humidity does. The process does not result in freezing nor make clouds disappear.

When warm air cools and the temperature drops to the dew point, certain phenomena occurs. The dew point is the temperature at which the air cannot hold all the moisture in it and some of it condenses as water vapor, leading to the formation of small droplets. The statements A 'Clouds form' and E 'Water droplets form on grass' best describe what will most likely happen, since clouds are formed due to condensation of water vapor in the air, and dew forms on grass for the same reason. Statement B 'Air becomes more humid' could be misleading; while it's true that the relative humidity increases (since it is defined as the ratio of the actual amount of water vapor in the air to the maximum amount of water vapor the air could hold at that temperature), the actual amount of water vapor does not increase. Statements C 'Solid ice forms on leaves' and D 'Cumulus clouds disappear' are not accurate as cooling to the dew point results in condensation, not freezing, and this process tends to create, not dissipate clouds.
