How is a spark from touching a doorknob the same as a bolt of lightning
Explanation:
That little spark you get when you touch the doorknob is essentially a miniature lightning bolt. When rain clouds move through the air, they build up positive and negative electric charges (Figure 7). So clouds have static electricity too! And when enough charge builds up, electric charges jump between the cloud and the ground.

Look at the diagram of the male reproductive system. Name the parts
Answer:
Explanation:
مرحبًا ، أود أن أحاول مساعدتك في عملك المدرسي. إذا كنت تستطيع أن تشرح أكثر فأنا أقدر ذلك.
The diagram of the male reproductive system. The parts names are 1. prostate gland, 2. Pe.nis, 3. Urethra, 4. Vas deference, 5. testis, 6. scrotum .
The biological process of creating offspring of the same sort is known as reproduction. It is one of the critical mechanisms that ensures the survival of the species generation after generation.
The testes, scrotum, spermatic ducts, male accessory glands, and pe.nis comprise the male reproductive system. All of these organs collaborate to make sperm, the male gamete, male sex hormones, and other semen components.
Pe.nis: It refers to the male genitalia. It consists of three cylindrical chambers filled with erectile tissue. The two larger ones, the corpora cavernosa, are side by side, and the third is the sinus, called the corpus spongiosum, which covers the urethra.
Scrotum: It is a thick skin sac that protects and surrounds the testicles. It also regulates the temperature of the testes, which must be slightly lower than body temperature in order to produce appropriate sperm.
Testes: In humans, there are two testes. The testes are located outside the body in a pouch known as the scrotum. They have oval bodies that are 4 to 5 cm long and 2 to 3 cm wide.
Male sex accessory ducts are known as vas deferens.
Urethra: It is a tube-like structure that connects the urine bladder and urinary meatus.
The male accessory glands produce fluid that feeds the sperm. It is known as seminal plasma. This fluid contains a lot of fructose, calcium, and enzymes. It is the largest volume of semen from which the sperm is released during ejaculation.
Thus, The parts names are 1. prostate gland 2. Pe.nis 3. Urethra 4. Vas deference 5. testis 6. scrotum .

Describe the ways mutations can affect DNA and chromosomes.
The mutation affects DNA and chromosomes by changes in the sequence of DNA or changes in the gene present on the chromosome.
What is mutation?The mutation is a sudden change in the structure of chromosomes or DNA. The smaller mutation affects the nucleotide base in DNA, while the larger mutation affects the genes present on the chromosomes.
The substance which causes mutation is known as mutagens. Mutation can cause problems in growth and development and affects the functioning of the body. When changes occur in chromosomes or DNA, they cause changes in the protein. Due to this, a different kind of protein is produced.
The mutation is caused by the insertion, duplication, deletion, and substitutions of a DNA sequence. Thus, mutation can affect DNA and chromosome in many ways.

what happans to DNA inside the necleus before meiosis begins?
Answer:
Before mitosis begins, the cell has already made new copies of each of its chromosomes. However, these new copies remain attached to the original chromosome. A dividing cell must be able to pull the copied chromosomes apart from the original copies, which is how the DNA is evenly divided when one cell splits into two.

Which list correctly identifies characteristics that protists share with animals?
A. Motile, Reproduce sexually, Photosynthetic
B. Motile, Multicellular, Photosynthetic
C. Motile, Eukaryotic, Reproduce Sexually
D. Motile, Prokaryotic, Multicellular
Answer:
C. Motile, Eukaryotic, Reproduce Sexually
Explanation:
I just took the Test
The list that depicts the characteristics animals and protist share is: C. Motile, Eukaryotic, Reproduce Sexually.
Protist and animals are classified as eukaryotic organisms, this is because they have a well-defined nucleus. Thus, both are eukaryotic.
Virtually all protists are capable of moving with the aid of structures such as pseudopodium, flagella or cilia. Also, animals possess well developed structures and organs for movement. Hence, protist and animals are motile.
Animals reproduce sexually through the fusion of male and female gametes to produce their offspring. Also, some protist such as Plasmodium reproduce sexually.
A photo collage showing the image of some protist is provided in the attachment below.
Therefore, the list that correctly describes the characteristics shared by protist and animals is: C. Motile, Eukaryotic, Reproduce Sexually.

Why is it important to have range of tools that can measure all parts of the electromagnetic spectrum
This tiny slice of the universe, speckled with galaxies near and far, tells the story of galaxy evolution over cosmic time Among the 10,000 or so galaxies
pictured here are newborns, adolescents, adults and retirees Like looking through a vast collection of family photos, astronomers are poring over this
comprehensive image to see how galaxies grew up, matured, and aged
This portrait of our universe's history is called the Hubble Ultra Deep Field (or HUDF). It is a minuscule patch of sky first targeted by the Hubble Space
Telescope in 2002 and revisited over and over again since then. This version of the HUDF is extra special though It combines observations of the field
taken with Hubble's Advanced Camera for Surveys and the Wide Field Camera 3 from 2002 to 2012, providing one of the farthest views into the universe
we've ever seen Plus, it includes light not just from the visible part of the spectrum but from the invisible) infrared and ultraviolet ranges, too, giving us
different details of the story of how galaxies came to be
Infrared light lets us see the universe's youngest galaxies. These galaxies lie far far away from us, and as their light travels across the universe, it gets
stretched by the expansion of space Wavelengths of visible light grow longer becoming infrared light by the time it reaches us Combining Hubble's
observations of the HUDF in visible and infrared light a team of astronomers led by Garth Illingworth of the University of California identified more than
5,500 galaxies in a central portion of the field some so faint that they are just one ten-billionth the brightness of what the human eye can see Another
team headed by Richard Ellis of the California Institute of Technology (Caltech) used Hubble's infrared observations to find galaxies more than 13 billion
light-years away, when the universe was only about 400 million years old - or about three percent of its present age
Alternatively, to understand slightly older growing galaxies that are not so far away, observing in ultraviolet light is best The hottest and youngest stars
give off huge amounts of ultraviolet light making them easy to spot at those wavelengths of light Most recently, a team of astronomers led by Harry
Teplitz of Caltech used the ultraviolet-sensing abilities of Hubble's Wide Field Camera 3 to add the ultraviolet piece to this view of the HUDF With this
part of the galaxy evolution picture in hand, astronomers are investigating how galaxies grew through bursts of star formation and exactly where when
and how many stars formed over time
Because our atmosphere blocks or absorbs most infrared and ultraviolet light that reaches Earth only a telescope in space, like Hubble, can provide
such insights into the history of galaxies Without both infrared and ultraviolet light, the tale is incomplete.
Answer:
the inly question i understood ::::: Why is it important to have range of tools that can measure all parts of the electromagnetic spectrum
ans
Because the electromagnetic spectrum comprises different types of electromagnetic radiation (radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays), all of which have different wavelengths and require different tools to measure them.

Which of the following is not a function of the skeletal system?
A.
provides a framework for the body
B.
provides protection for internal organs
C.
movement of bones
D.
production of new blood cells
Answer:
C
Explanation:
The skeleton relies upon the contraction and relaxation of muscles which are attached to bone in order to move. The muscular system is made up of three types of muscle, one of which is responsible for the movement of bone. To add to the confusion, the relationship between both muscles and bones is often lumped together as the musculoskeletal system, but to be sure, they are unique in their own ways.
In summary, bones can't move on their own, and therefore movement cannot be the skeletal system's function.
What happens to a CO2 molecule when an infrared wave hits it?
The energy from the photon causes the CO2 molecule to vibrate. Some time later, the molecule gives up this extra energy by emitting another infrared photon. Once the extra energy has been removed by the emitted photon, the carbon dioxide molecule stops vibrating.
