Why is water considered to be abiotic?

Answers

Water is considered an abiotic factor in the ecosystem because it is a non-living part of the ecosystem. Water is very important to al living things and no living organism can survive without it. Other abiotic factors in the ecosystem are soil, rocks, sunlight, oxygen, etc.

Answer: Water is a nonliving factor so it is considered abiotic. Abiotic is any nonliving factor of the ecosystem, With said that water is not living so it is considered abiotic. Hope this helps.

Your teacher places the following supplies on a table: water, hot plate, salt, beakers, food coloring, and test tubes. Using the supplies listed, how could you plan an investigation of how differences in temperature and salinity affect ocean currents? Include the following vocabulary in your explanation: salinity, density, temperature, wind, surface currents, deep currents. Make sure to include specific details and steps.

Answers

Answer:

Higher saline water is more dense that lower saline water

Explanation:

The ocean salinity varies with rainfall, run off from estuaries and the pattern of ocean current.  In addition to this, higher temperature affects the kinetic movement of water as well as the salinity. The movement of the wind also contributes to the movement of water and the particles and solute distribution.  The surface currents do not do much to mix the entire body of water and this is because this is from less dense areas. Deep currents factor in to mix just the heavier more dense layers.

In planning an experiment to test this one would do two experiments.

First: Heat 4 batches of water at different temperatures and color the different temperatures with different food coloring. Next layer the water carefully from hottest to coldest in a beaker and then from coldest to hottest in another beaker.

Second: Dissolve salt in 4 batches of water increasing the amount by half each time. Color each with different food colouring and layer the salty water from least salt to most salt in a beaker. Layer the water from most salt to least salt in another beaker.

Make observations:

The cooler water should be more dense and sink to the bottom while the saltier water should be more dense and sink to the bottom.

In organ transplants, the body recognizes that the new organ is made of foreign cells. What kind of medicine would you give a patient to increase the chances of transplant success?

Answers

Answer:

immunosuppressant

Explanation:

After an organ transplant, you will need to take immunosuppressant (anti-rejection) drugs. These drugs help prevent your immune system from attacking ("rejecting") the donor organ. Typically, they must be taken for the lifetime of your transplanted organ.

All cells reproduce to make new cells. However, stem cells actually form many different types of cells. Adult stem cells can also repair tissues in the body.

What is a “shared derived character”?

Answers

Answer:

A shared character is one that two lineages have in common, and a derived character is one that evolved in the lineage leading up to a clade and that sets members of that clade apart from other individuals. 

Answer:

A shared character is one that two lineages have in common, and a derived character is one that evolved in the lineage leading up to a clade and that sets members of that clade apart from other individuals. Shared derived characters can be used to group organisms into clades. For example, amphibians, turtles, lizards, snakes, crocodiles, birds and mammals all have, or historically had, four limbs. If you look at a modern snake you might not see obvious limbs, but fossils show that ancient snakes did have limbs, and some modern snakes actually do retain rudimentary limbs. Four limbs is a shared derived character inherited from a common ancestor that helps set apart this particular clade of vertebrates.

When the total lunar eclipse occurs what are the relative positions of the sun earth and moon

Answers

Answer:

A lunar eclipse occurs when the Moon passes directly behind the Earth into its umbra (shadow). This can occur only when the sun, Earth and moon are aligned (in "syzygy") exactly, or very closely so, with the Earth in the middle.

Explanation:

Answer:

The earth is between the sun and the moon

Explanation:

The Moon is non luminous that is doesn't generate light by itself so it depends on light from the sun so when its path through which it taps light from the sun is totally covered it means the Earth is closer to the moon than the Sun so that the Earth gets all off its light leaving nothing for the Moon and in this case the Moon is thrown to total darkness.

BY USING FOREST WISELY;

It was learnt that people are cutting trees at an worrying rate.This problem is disturbing because ;

1)Those trees are responsible for releasing of oxygen and they made up at least a quarter of the world population.

2) Those trees of the world make up of portion land species by more than forth or fifth portion.

There are also economic implications as a result of trees been cut down, when there is no availability bot trees , it could result to situation whereby there would be scarce of resources for industries as well as

hike price of paper in market, regardless of this trees are needed for manufacturing of important materials such as usage in making houses and others developments or growth

Therefore, all the afformentioned economic concern result in economics delay scientists' first attempts.

COMMUNITY CONSERVATION;

It was learnt that there is to the forest that those gorilla habitated, those human being that reside in those region reside there so they can practice their farming because their is available land there. They also reside there because of housing.

These gorillas were affected as a result of the destruction made to their habitat as well as the activities of the poachers that hunt them for production of the and skin.

There are adverse effect of the obliteration of the gorilla from on the society, it can result to having reduction in tourism in country such as

Uganda as well as Rwanda, as result of this the means of livelihood of people in that part could be affected because there would be Reduction in profit making. Hence the reason behind the increase in number gorillas in the region, because they know they know that those gorilla influence the number of tourist that comes there and the revenue that is generated through this tourism.

The article 'By using Forest Wisely' can be summarised as:

People are cutting trees at the wrong rate and trees play a crucial role in an ecosystem.

The trees produce oxygen and they made up at least a quarter of the world population.

The trees occupy the fourth or fifth portion of the land organisms.

In the absence of trees, the ecosystem will fail and the organisms dependent on them will eventually die.

The resources available from the trees will be scarce and the factories and industries that are dependent on trees will no longer be available.

Trees are required for manufacturing important materials.

The article 'Community Conservation' can be summarised as:

In the article, it was mentioned that the human populace urbanized the land region where gorillas were habituating.

The humans occupied the space to practice farming and make houses.

The population of the gorillas was disturbed and diminished.

The hunting of gorillas by poachers was also reduced.

The people of Uganda and Rwanda also suffered reduction tourism and conservation of wildlife.

Gorillas influence the number of tourists, therefore, the destruction of their habitats led to a reduction in profit-making.

Therefore, all the mentioned economic concerns result in economics delaying scientists' first attempts.

Why do we need human dna

Answers

DNA. Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions for the development and function of living things.

All known cellular life and some viruses contain DNA. The main role of DNA in the cell is the long-term storage of information.

We need human DNA since it give us the long term info storage, which is needed

DNA contains instructions for development, survival, and reproduction. DNA sequences must be translated into signals to make proteins, which do most of our body's job.

What is human genome?

DNA stores the instructions that are necessary for an organism to grow, maintain its existence, and reproduce itself. In order for these duties to be carried out, the sequences of DNA need to be transformed into messages that can be utilized in the production of proteins. Proteins are the complex molecules that are responsible for the majority of the work that is done in our bodies.

The human genome is comprised of all of the nucleic acid sequences that are found in humans. These sequences are stored as DNA within the 23 chromosome pairs that are found in the nucleus of cells, as well as in a tiny DNA molecule that is located within the mitochondria of each individual cell. In most cases, these are considered to be two distinct components: the nuclear genome and the mitochondrial genome.

Can somebody help with those 3 problems please

Answers

Answer:

first one is option A

second one option B

third is26 N

Explanation:

1.the law here is every action has an equal and opposite......

2. only unbalanced forces move objects from rest or of uniform motion

3.net force is the sum of forces ,if forces are in the same direction

hope this helps plz mark me brainliest

2) Option A.
Force is directly proportional to the mass. As the mass of the fuel deceases as the fuel is burnt, the force also decreases as force is directly proportional to mass, and as the force decreases, the acceleration decreases as acceleration is also directly proportional to the force, and the shuttle may eventually come to a stop due to the increasing deceleration. However, initially if the forces are kept balanced as the space shuttle and the gases exert an equal amount of force on each other in the directions opposite to each other, the object will keep on moving upwards in a constant velocity as the amount of force is also kept constant.


3) Option B.
The motion will definitely change when the forces acting on an object are unbalanced-it will start to move, accelerate or decelerate or change its direction in the direction of the net force. The object will not move at all or continue moving with the same velocity and in the same direction if the forces acting on it are balanced or zero.

4) When the forces are unbalanced and are acting on an object in the same direction, the net force will be found by finding the sum of those forces.
Net force=17+9=26 N.
