Animal use chlorophyll to produce glucose.
True
False
Answers
explanation plants do
Animals use chlorophyll to produce glucose. This is a false statement. Hence, the correct answer is second one . Animals are not autotrophs but heterotrophs.
What is photosynthesis?Photosynthesis is a process in which oxygen and glucose are produced from carbon dioxide and water with the help of sunlight in green plants. This reaction is carried out by the green plant because it consists of chloroplasts.
The chloroplast is the organelle that has chlorophyll pigment, and this pigment is responsible for the photosynthesis process. Due to this, plants are called producers. Animals depend upon the plant for food and are called heterotrophs. Animals cannot do photosynthesis.
In different ecosystems, different producers are present, such as in aquatic ecosystems, where algae and seaweeds perform this function. In terrestrial ecosystems, plants perform this photosynthesis. Consumers feed them depending on the producers, and after both the consumer and the producer die, both are decomposed by decomposers.
Hence, animals use chlorophyll to produce glucose; this is the false statement.

Look at the diagram of the male reproductive system. Name the parts
Answers
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 .

I will mark you Brainly.
Answers
Answer:
There are many rappers out there in the world yet only a few of them are really well known and recognized. Of course this is because they meet peoples expectations. Different people have different opinions on what makes a good rapper. Things that I think make a good rapper is that they need to have good flow, meaningful lyrics that actually make sense and not just rhyme any word with another that doesn't make sense. Another thing is how they are like as a person as well. If they are a pretty decent human being and meets peoples expectations then they will be considered as a good rapper. If the person is not only ignorant but also can't rap well then they are considered bad. Like I said many people have different opinions but these are just mines.

Eyepiece magnification(EM) X Objective magnification (OM)= Overall Magnification:
Answers
Answer:
I. Overall magnification (TM) = x40
II. Overall magnification (TM) = x100
III. Overall magnification (TM) = x400
IV. Overall magnification (TM) = x1000
Explanation:
A microscope can be defined as an optical device that is typically used to make an enlarged (magnified) image of a minute (small) object and as such reveals all the little information about the object that cannot be seen by the natural human eye.
Mathematically, the overall (total) magnification of a microscope is given by the formula;
Overall magnification (TM) = Eyepiece magnification(EM) X Objective magnification (OM).
I. When EM = x10 and OM = x4
TM = EM * OM
TM = x10 * x4
TM = x40
II. When EM = x10 and OM = x10
TM = EM * OM
TM = x10 * x10
TM = x100
III. When EM = x10 and OM = x40
TM = EM * OM
TM = x10 * x40
TM = x400
IV. When EM = x10 and OM = x100
TM = EM * OM
TM = x10 * x100
TM = x1000

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.

Explanation:
High-energy electrons supply the needed energy to synthesize ATP from the lower-energy ADP in the electron transport chain. So, the correct option is (B).
What is Electron transport chain?An electron transport chain is defined as a series of protein complexes and other molecules that transfer electrons from electron donors to electron acceptors through redox reactions and that link this electron transfer with the transfer of protons across a membrane.
Large amounts of ATP can be produced through a highly efficient method called oxidative phosphorylation where ATP is a fundamental unit of the metabolic process. Electrons are transferred from electron donor to electron acceptor thereby producing ATP which is the important step of Electron transport chain.
Thus, high-energy electrons supply the needed energy to synthesize ATP from the lower-energy ADP in the electron transport chain. So, the correct option is (B).

If a SARS-CoV2 virus were to mutate and become and become better at attaching to respiratory cells, how would natural selection lead to this mutant virus becoming the dominant virus type? Use the four steps of natural selection in your response: overpopulation, genetic variation, competition, differential reproductio.
Answers
Answer:
Mutations leading to the better attachement of virus to the host cell would allow the virus to spread the infection and leave more progeny. The reproductive fitness of mutant viruses would allow the mutation to spread.
Explanation:
1. The organisms with same resource requirement compete with each other. Viruses are not living things but once inside the host cell, they behave like living things. Rapid multiplication of virus overpopulate the host cells.
2. Genetic variations are added to the viral progeny by random errors during replication of the viral genome. These random variations may impart beneficial trait, harmful feature or remain neutral. If a random mutation in the SARS-CoV2 virus allows it to adhere better to the cells of the respiratory system, the virus would be better able to infect these cells to spread the infection. Once inside the host cells, the mutant virus would leave more progeny. On the other hand, the wild type virus that lack this mutation would have lesser chances of entering the host cells and may or may not replicate.
3. The progeny of the mutant virus would compete better with the non mutant ones due to the presence of same mutation.
4. Differential reproduction and more progeny of the mutant virus would spread the mutation among the virus.
