In order for a light bulb to be turned on in a circuit, it must have what kind of switch?
Answer:
It must have a closed switch.
Explanation:
The current cannot flow through the full circuit if the switch is open, therfore the light won't switch on. However, if the switch is closed, the current can run through the circuit and the light bulb will switch on.

O a luminous object travels alongside an observer
O a distant luminous object travels rapidly towards an observer
O a distant luminous object travels rapidly away from an observer
O a luminous object is stationary compared to an observer
Pls help I will give 21 points if it is correct
Answer:
(b) a distant luminous object travels rapidly towards an observer.
Explanation:
Blueshift is observed when a distant luminous object travels rapidly towards an observer. The correct option is B.
What is blueshift?The displacement of an approaching celestial body's spectrum toward shorter wavelengths is known as blueshift.
When an object moves away from us, the light it emits is known as redshift; when an object moves towards us, the light it emits is known as blueshift.
The blue and red shift of stars cannot be seen with the bare eye. There are several reasons for this.
First, even for an object moving at thousands of kilometers per hour, the effect is minor, with only a slight change in hue.
Red light, with both the longest wavelength, is at one end of the spectrum.
The shortest wavelength is blue or violet light. White light is a blend of all the colors in the color spectrum. It has every color of the rainbow.
Thus, the correct option is B.

1. A rapidly increasing human population is the primary driver behind what
LEADING cause of the loss of biodiversity? (SEV5.a) *
O a. Extinction
O b. Habitat Loss
O c. Pollution
O d. Overexploitation
Answer:
your answer is B. Habitat Loss
Explanation:
What is the #1 cause for the loss of biodiversity?
Habitat destruction
Habitat destruction is a major cause of biodiversity loss. Habitat loss is caused by deforestation, overpopulation, pollution, and global warming. Species that are physically large and those living in forests or oceans are more affected by habitat reduction.
Habitat loss and overexploitation, driven by our rapid population growth and unsustainable consumption patterns, are the primary causes of biodiversity loss which is now happening up to ten thousand times faster than for millions of years before.
suppose you and a friend are making iced tea using identical glasses. You both use the same amount of water, and the water temperature is the same in both glasses. Explain how you can tell who added more ice tea mix to the glass.
Answer:
Iced-Tea Problem
220 g of 35˚C tea (water) is poured over 250 g of -10˚C ice.
What happens...
The warm water (tea) will cool down to 0˚C. As it cools the ice will heat up to 0˚C and then start to melt.
There is plenty of ice however and only a portion of it will melt. Find the amount of ice that melts into water
and you’ll know the final composition and even the dilution factor on the tea.
Cool tea water down to 0˚C
4.184 J/g˚C · 220 g · 35˚C = 32216.8 J removed to cool tea to 0˚C
Warm ice up to 0˚C
2.09 J/g˚C · 250 g · 10˚C = 5225 J to heat ice up to 0˚C
This heat comes from the cooling water, so substract this amount off the total above
32216.8 - 5225 = 26991.8 J of heat that will MELT the ice
mass of ice melted = 26991.8 / 334 = 80.8 g of ice melted
220 g + 80.8 = 300.8 g of water
250 g - 80.8 = 169.2 g of ice
final mixture for
my glass of iced
tea all at 0˚C
220.0 g original tea
300.8 g final tea
The dilution factor is simply the original volume
over the final volume (or masses here ). = .731 or 73.1%
of the original
concentration
If I’m going to get a dilution of 73.1%, I should
compensate by mixing my tea in 26.9% LESS
volume than the directions state. So I will not dilute
the tea to 2 quarts (64 oz), but rather to 1.462
quarts (46.8 oz).
It’s hot and I want a glass of iced tea as soon as possible. The directions for my tea say to boil some water,
add 2 tea bags (these are the big bags), steep for 4-5 minutes, then add enough water to make 2 quarts which
turns out to be a pitcher of tea. However, if I make this tea the exact concentration I want now, when I pour
it over ice the ice will melt (because the tea will still be quite warm) and my tea will be too dilute. So I
calculate how much stronger I should make the tea KNOWING I will pour the warm tea over ice to make
my glass of iced tea.
(a). What is the final temperature and composition of the glass of iced-tea?
(b). What will be the concentration of the tea relative to the original concentration?
(c). How concentrated should I mix the tea knowing that it will be diluted when
poured over the ice?
(a)
(c)
(b)
only 73.1% of the full
amount to compensate
for dilution

An arrangement of all the chromosomes of a diploid cell is called a(n)
Answer:
An arrangement of all the chromosomes of a diploid cell is called a kayrotype
An arrangement of all the chromosomes of a diploid cell is called a karyotype is the overall look of all the chromosomes in a species or an individual organism's cells.
What is the karyotype?A karyotype is a eukaryotic cell's nucleus' number and arrangement of chromosomes. The phrase is also used to refer to a species or an individual organism's entire set of chromosomes.
Each diploid cell in humans contains 46 chromosomes. There are 22 pairs of autosomal, or non-sex, chromosomes and two chromosomes that determine sex among them. A diploid cell has 2n total chromosomes, which is twice as many as a haploid cell's total chromosomes (n).
Therefore, a karyotype is the overall look of all the chromosomes in a species or an individual organism's cells, primarily their sizes, numbers, and shapes.

An example of a communicable disease is giardiasis, which is in option D. Giardiasis is an example of a communicable disease. It is caused by a microscopic parasite called Giardia lamblia.
This disease affects the digestive system, causing symptoms such as diarrhea, abdominal cramps, bloating, and nausea. It is typically transmitted through the ingestion of contaminated food or water that has been contaminated with the parasite. Chronic respiratory disease includes conditions such as asthma, chronic obstructive pulmonary disease (COPD), and bronchitis, which are usually caused by long-term exposure to irritants or genetics and are not directly communicable.

During the match, the heartbeat rate of the football fans and players increases. Explain the relationship between the heartbeat rate and the activities of the football fans and the players. (10 marks]
Answer:
Adrenaline
Explanation:
The adrenaline glands, located on top of both kidneys, are glands that produce hormones to regulate blood pressure, bodily functions, metabolisms, etc. Adrenaline is released whenever the blood is redirected towards the muscles, causing surges of energy. In general, adrenaline increases blood flow in your body, which causes the heartbeat to increase, or give the feeling of a racing heart. Between the football players and the heartbeat rate, they are getting rushes of adrenaline from either participating in the game or cheering on their team from the sidelines. Hope that made sense.
Why did Ibrahim conclude that the dorsal spines were not used to support a hump or to regulate body
temperature?
Chemical composition of dorsal spines provides information about its function as regulation of body temperature.
The dorsal spines were not used to support a hump or to regulate body temperature because of the chemical composition of the spines. Ibrahim found that the spines were made up of bones having few blood vessels and were likely wrapped tightly in skin which can't perform the function of thermoregulation in the body.
In order to regulate temperature of the body, more blood vessels are needed and we know that in dorsal spines the structure is bony and less number of blood vessels so we can conclude that chemical composition of dorsal spines provides information about its function as regulation of body temperature.
