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.

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.

3. How did economics delay scientists' first attempts for conservation in each story?
4. Describe the political actions that led to successful conservation in both stories.

Answer:

Explanation:

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.

The pattern of natural selection where BOTH of the extreme versions of a trait are more advantageous than the average, so a population evolves in both directions away from the average.

Answers

Answer:

Stabilizing Variation.

Explanation:

This is the type of variation that occurs when genetic diversity decreases as the population of organism in a particular population based on a specific trait.

Organisms with varied or specific  traits within the population are selected against by the selection pressure,  with little chances of reproduction, while organisms in between, ( with least variation of  this particular traits) which are within the narrow range, survive to reproduce.Thus, this gives  rise to narrow population  of these  particular organisms,(stabilizing variation) which are therefore naturally selected.

Therefore, the variation of the organisms in this population is kept  close to the  centre of  the same  mean value.
