What is cancer ?
Cancer is a disease in which abnormal cell growth occur with the help of uncontrolled cell division and spread to other parts of the body. If it is fixed to one specific area of the body called as benign whereas if it spreads over different parts of body called as malignant.
In case of normal cell growth when human cells will grow and multiply to form new cells, when become old it will get damaged; In case of cancer mainly caused by genetic changes that control the way our cells function.
These Genetic changes that cause cancer include errors in cell division, damage of DNA due to harmful substances in the environment like chemicals in tobacco smoke and ultraviolet rays, also inherited from parents.
gamma rays which is the most powerful radiation energy could be focused to a pin point, and kill cancer cells with out harm the adjacent normal tissue, Now a days Gamma knife device is used to treat brain tumors.

In Drosophila melanogaster, the fruit fly, the gene for the eye color is X-linked. So in this species:
- X⁺ expresses red eyes ----- > + is the dominant allele for red color
- X⁻ expresses white eyes ----> - is the recessive allele for white color
Option 1: true-breeding red-eyed females and white-eyed male

Why is the cell cycle so tightly controlled in multicellular organisms?
Answer:
All multicellular organisms use cell division for growth and the maintenance and repair of cells and tissues. Cell division is tightly regulated because the occasional failure of regulation can have life-threatening consequences.
All multicellular organisms use cell division for growth and the maintenance and repair of cells and tissues. Cell division is tightly regulated because the occasional failure of regulation can have life-threatening consequences.
What is cell cycle?Cell cycle has been as the defined as cycle in which cell produces, grows and divides. The cell cycle has mainly three steps the first one has G1 phase in which the size of the cell increases, S phase synthesis of DNA takes place and the third step has G2 phase in which all cell ready to divide.
Cell has been defined as the base of the life as it has the structural as well as functional unit of life. Cell has been made up of pre existing cells and the cell contain various part cell organelles such as mitochondria, endoplasmic reticulum, ribosomes, golgi appratus, nucleus, and cytoplasm.
Therefore, All multicellular organisms use cell division for growth and the maintenance and repair of cells and tissues. Cell division is tightly regulated because the occasional failure of regulation can have life-threatening consequences.

how does sickle cell anemia mutation impact the structure and function of the protein produced
Answer:
The beta globin protein is one of the subunits of hemoglobin, a protein necessary for the oxygen-carrying function of red blood cells. People with the sickle cell mutation in both copies of the HBB gene produce proteins that clump together and lead to changes in the shape and behavior of red blood cells.

Which of the following diagram(s) accurately depict high turgor pressure in a plant?
Answer:
I believe it's B
Explanation:
The diagram that accurately depicts high turgor pressure in a plant is diagram B. The correct option is B.
What is the turgor pressure?The pressure that pulls the plasma membrane up against the cell wall is known as turgor pressure. It is also known as hydrostatic pressure and is known as the pressure in a fluid when it is at equilibrium and is measured at a specific spot within the fluid.
Therefore, the turgor pressure helps the plant's cells elongate, and the cells also employ this phenomenon to control transpiration by opening and closing the stomach.
Water is held in vacuoles, which are organelles in plant and fungus cells that are surrounded by a single membrane.
The turgor of a living cell is influenced by three primary factors:
An adequate supply of water.The formation of osmotic substances.A semi-permeable membrane.Therefore, the correct option is B, diagram B.

A ball is dropped from the top of a building’s roof. What is the acceleration of the ball?
Explain how satellites and orbits work.
Answer:
The motion of a ball falling down through the atmosphere, or a model rocket being launched up into the atmosphere are both examples of Newton's first law. The motion of a kite when the wind changes can also be described by the first law.
Newton's Second Law of Motion says that acceleration (gaining speed) happens when a force acts on a mass (object). Riding your bicycle is a good example of this law of motion at work. Your bicycle is the mass. Your leg muscles pushing pushing on the pedals of your bicycle is the force.
Other examples of Newton's third law are easy to find. As a professor paces in front of a whiteboard, she exerts a force backward on the floor. The floor exerts a reaction force forward on the professor that causes her to accelerate forward.
It is summarized by the equation: Force (N) = mass (kg) × acceleration (m/s²). Thus, an object of constant mass accelerates in proportion to the force applied.
Friction is the force that opposes motion between any surfaces that are in contact. There are four types of friction: static, sliding, rolling, and fluid friction.
Static, sliding, and rolling friction occur between solid surfaces. ...
Fluid friction occurs in fluids, which are liquids or gases.
increase the force on an object the acceleration increases proportionally. Since the mass does not change as the acceleration increases, we can say that force is equal to acceleration. Therefore, if you double the force you double the acceleration.
If you increase the mass at a given force the rate of acceleration slows. Therefore, mass is inversely proportional to acceleration.
The net force is the vector sum of all the forces that act upon an object. That is to say, the net force is the sum of all the forces, taking into account the fact that a force is a vector and two forces of equal magnitude and opposite direction will cancel each other out.
Newton's law also states that the strength of gravity between any two objects depends on two factors: the masses of the objects and the distance between them. Objects with greater mass have a stronger force of gravity between them. ... Objects that are closer together have a stronger force of gravity between them.
Some people think that there is no gravity in space. In fact, a small amount of gravity can be found everywhere in space. Gravity is what holds the moon in orbit around Earth. ... It is possible for a spacecraft to go far enough from Earth that a person inside would feel very little gravity.
The mass is essentially "how much stuff" is in an object. ... Weight: There is a gravitational interaction between objects that have mass. If you consider an object interacting with the Earth, this force is called the weight. The unit for weight is the Newton (same as for any other force).
You can enter your weight in any unit you wish
If you are talking about these objects on Earth, then the gravitational acceleration is around 9.81 m/s2 . We know that weight is given by the formula, W=mg , where m is the mass of the object in kilograms, and g is the gravitational acceleration.
Satellites are able to orbit around the planet because they are locked into speeds that are fast enough to defeat the downward pull of gravity. ... A satellite maintains its orbit by balancing two factors: its velocity (the speed it takes to travel in a straight line) and the gravitational pull that Earth has on it.
