Answer: The drug abuse is influenced by the environment and exerts influence on the gene expressions.

Explanation:

The genetic make up of the person is decides, which genes will be expressed and develop a trait in an individual. But this genetic expression can be influenced by the environmental factors like food, exposure to sunlight, and others. This study which relate environment with the genetic make up is called epigenetics. No person is drug addict by birth but the consumption of drug can influence the genetic make up and traits in a abuser. So here, the environment is influencing the genetic basis of a abuser.

Answer:

Holmes proposed that the continents, which “floated” on the Earth's mantle, moved with the convection flow of the magma (hot semifluid below the Earth's crust). The mechanism of continental drift is like the flow of branches floating in the moving waters of rivers, as shown in Figure 3-11.4.

Answer:

Mitosis is essential to the regeneration of tissue because during Mitosis, cells replicate to create a daughter cell that is the exact copy of the parent cell.

Explanation:

The reason this is so important is because stem cells can develop into nearly any cell type. Mitosis allows these cells to replicate the exact cell type needed (in this case, tissue), and create a daughter cell that has the same exact components and characteristics of the parent cell.

Radiation has been the mode of thermal energy transfer from a source. "A snake’s body temperature increases when the snake lies in the Sun" is an example of radiation. Thus, option B is correct.

Radiation has been the type by which the thermal heat energy passes from the source to the other site. It has been independent of contact and involves traveling in space with the equivalent speed of light. Unlike conduction and convection, radiation does not need matter.

The particles tend to move in space like the sun's rays heating the earth. When a snake lies in the sun its body temperature rises due to tradition as the solar energy from the sun (high temperature) moved in space to the lower temperature (snake's body).

Therefore, option B. heating the snake's body under the sun is an example of radiation.

Explanation:

In the beginning, there was an infinitely dense, tiny ball of matter. Then, it all went bang, giving rise to the atoms, molecules, stars and galaxies we see today.

Or at least, that's what we've been told by physicists for the past several decades. 

But new theoretical physics research has recently revealed a possible window into the very early universe, showing that it may not be "very early" after all. Instead it may be just the latest iteration of a bang-bounce cycle that has been going on for … well, at least once, and possibly forever. 

Of course, before physicists decide to toss out the Big Bang in favor of a bang-bounce cycle, these theoretical predictions will need to survive an onslaught of observation tests.

The initial singularity is a singularity predicted by some models of the Big Bang theory to have existed before the Big Bang and thought to have contained all the energy and spacetime of the Universe.

The correct designation for predicting a cross between two heterozygous organisms is: D. AaBb X AaBb

Reproduction refers to a biological process which typically involves living organisms (parents) mating to produce offspring.

Basically, there are two (2) main types of reproduction and these include;

Crossbreeding can be defined as the process of producing offspring by mating two (2) pure-breed living organisms (parents) of two (2) different breeds, varieties, or populations but within the same species.

For two heterozygous living organisms, the correct designation for predicting a cross between them is AaBb X AaBb.

In conclusion, the allele of a cross between two heterozygous living organisms are either dominant or recessive.

Answer:

4. wedge and lever

Explanation:

Simple machines are mechanical devices which make our work easier. Examples are : lever, wedge, wheel and axel, pulley, screw and an incline plane.

A stapler is a made up of a level which is the handle part and a wedge which are the staples.

A pulley is a simple machine that has one or more wheels connected with a rope in a loop to make lifting of loads easier because it changes the direction of force applied/pull thus multiplying the force applied. A stapler does not have the wheel and the rope thus answer choice 1 and 2 are incorrect.

A screw is a simple machine that applies torque on a shaft to produce a large axial force on the load. It utilizes the conversion of rotational motion to a linear motion and a torque to a linear force. A stapler mechanism does not involve rotational motion or rotational force, hence answer option 3 is incorrect.

A stapler is made up of a combination of two simple machines: the wedge and the lever. The correct option is 4.

A stapler utilizes a wedge to perform its primary function. The wedge is the part of the stapler that drives the staple through the paper. It has a sharp, triangular shape that allows it to exert a large amount of force over a small area, making it easier to pierce through the materials.

The stapler also incorporates a lever mechanism. The lever is the long arm of the stapler that is pushed down to drive the wedge and staple into the paper.

By applying force at one end of the lever, a mechanical advantage is gained, allowing the user to apply a smaller force to produce a greater force output at the other end, making it easier to staple multiple sheets of paper together.

Therefore, The correct option is 4.
