What are the 3 structures that leave from the kidney?
Answer:
an outer cortex, a medulla in the middle, and the renal pelvis in the region called the hilum of the kidney.
Explanation:
Internally, the kidney has three regions—an outer cortex, a medulla in the middle, and the renal pelvis in the region called the hilum of the kidney. The hilum is the concave part of the bean-shape where blood vessels and nerves enter and exit the kidney; it is also the point of exit for the ureters.
Situaciones comunicativas y qué tipo de comunicación se utiliza comunicación oral o comunicación escrita.
Answer:
Una llamada telefónica, utiliza comunicación oral.
Una charla entre amigos, utiliza comunicación oral.
Leer un mensaje, utiliza comunicación escrita.
Un artículo en una página web, utiliza comunicación escrita.
Explanation:
La comunicación oral se caracteriza por ocurrir entre dos o más personas de manera directa, espontánea y simultánea. Se utiliza la voz para emitir el mensaje y la audición para recibirlo. El código es oral y no permanece en el tiempo.
En la comunicación escrita el mensaje se transmite por un código escrito. El emisor escribe el mensaje y el receptor lo lee. El mensaje no es simultáneo sino que se interpreta luego de que fue emitido, es decir cuando se lee una vez recibido, por ejemplo cuando el destinatario recibe la carta. La comunicación oral a diferencia de la escrita no es espontánea sino que se planifica lo que se va escribir. Por último, el mensaje permanece en el tiempo ya que está escrito.
When do the scientists working in the exclusion zone need to wear all of their protective gear? For radioactive wolves
Answer:
all the time
Explanation:
The radioactive wolves is a documentary film made on the Chernobyl radioactive disaster. This place is known as the Chernobyl exclusive zone and human trespasses is prohibited here.
A team of scientist went to the Chernobyl exclusive zone to do some research on the life of the wild animals in that place after the disaster. A large number of animals now are carrying particles of radioactive elements in their body and is roaming in the forests of the world.
So the scientist visiting the exclusive zone must wear the protective gears all the time they are in the place so as to prevent themselves from exposing themselves to the radio active elements.

Which diagram best illustrates the flow of energy in an ecosystem?
Answer:
The correct answer is - option B.
Explanation:
The diagram or pyramid for the energy flow of an ecosystem represents the flow of energy from one end to the other end according to the food chain. It starts with the ultimate energy source the sun which is used by the producers to produce energy and this is the trophic level that carries the highest energy.
In the food chain, when primary consumers eat the producers they get 10% of the total energy producers carries due to loss of energy and 10% energy of primary consumer have transferred to secondary consumer and so on.
The table below shows part of the process of DNA replication:
Original DNA Strand
Complementary DNA Strand
A-C-C-G-T-A-C
T-G-G-A-A-T-G
What is the most likely effect this could have on genetic information going forward?
оооо
There will be no change in the genetic information that gets transmitted because the complementary strand will never be used as a template
O There will not be a change in the genetic information that gets transmitted because the cells having the new section of DNA will correct any mutations
There will be a change in the genetic information that gets transmitted due to the complementary strand being used as a template in future DNA replication
There will be a change in the genetic information that gets transmitted because the sections of DNA with mistakes will be passed on to make future generations stronger.
Answer:
There will be a change in the genetic information that gets transmitted due to the mutation in the complementary strand being used as template in future DNA replication.

how do variations lead to adaptations?
Answer:
Favorable variations may allow an organism to be better adapted to its environment and survive to reproduce. Beneficial traits are favored in a population so that they may become better represented. Changes in the genetic makeup of a species may result in a new species; this is biological evolution.

Earth is special because it is an ocean planet. Water covers 70 percent of Earth's surface. Earth's atmosphere is made mostly of nitrogen and has plenty of oxygen for us to breathe.There are multiple reasons for earth to be a special planet. Reasons are as follows
1.Earth is the only planet known where intelligent life exist.
2.It lies in the circumstellar habitable zone (CHZ). CHZ is defined in the image given below.
3. Earth has a unique magnetic field which protects the earth from the harmful solar winds. These solar winds played a role in transforming venus into hell.
4. Earth has Van Allen radiation belts which protects it from cosmic rays.
5. Our large neighbour Jupiter protects is from many comets and asteroids that come from the keiper belt and Oort cloud.
6. Earth's atmosphere is favorable to support life on earth. This atmosphere consists of different gases in adequate amount. If the percentage of gases would differ then life on earth may face serious consequences.
7. Tectonic plates of earth differentiates it from most other planets.
8. Earth has a solid crust unlike the gaseous planets.
9. Earth has been gifted with a medium sized star which release solar winds and protect us from the harmful radiation of outer space.

Explanation:
why do some scientists think the "origins" question cannot be answered scientifically?
I personally think because of the intelligent design vs. evolution theories. what do you think?
Answer:
agreed
Explanation:
for certain things like how humans were created and everything like that I totally agree because you can't really do research if something that over the years is probably either hidden or gone so if there wasn't any evidence of how any of this came to be by now it would be gone. some things you just can't put a logical explanation on

[URGENT!!] David feeds his cattle with root vegetables such as turnips. Which type of feed includes root vegetables such as turnips?
A. concentrates
B. dry roughage
C. green roughage
D. silage
E. dry matter
Answer:
D.
Explanation:
Answer:
Green Roughhage
Explanation:
Roughages are high in fiber and low in digestible nutrients. There are three kinds of roughages: dry, green, and silage. Dry roughage such as hay has a low moisture content. Grasses in pastures and root vegetables (like turnips) are called green roughage and have a high moisture content. The fermentation of green plants results in the formation of silage.
Please help, 100 points! Most scientists agree that life began on earth approximately 3.5 billion years ago. What would a scientist need to do in order to test this hypothesis and gather evidence?
A: Recreate the composition of the atmosphere and oceans on Earth as they were 4.5 billion years ago.
B: Travel to a similar planet or moon in its own early formation and recreate the chemical reactions which took place on Earth.
C: Gather the raw materials, such as inorganic compounds, on Earth 4.5 billion years ago and recreate the chemical reactions that could have taken place.
D: This is not a testable hypothesis since there is no way to travel back 4.5 billion years or to run the experiment for the next 4.5 billion years. (This one is obviously wrong)
Around 3.8 billion years ago, near the conclusion of this phase known as the late heavy bombardment, life on Earth first emerged, hence option A is correct.
What is the origin of life?Even before the 3.5 billion years ago when the oldest fossils on Earth were discovered, just at the conclusion of the time of late intense bombardment, there is evidence of biological activity.
The 3.5 billion-year-old "stromatolites," which are hard structures created by bacteria, also provide evidence of their presence. Stromatolites are produced when microbe-made sticky mats catch and organize sediments into layers.
It has been discovered that trophozoites contain organic material from 3.5 billion years ago. 3.5 billion-year-old rocks have been found to contain microbial remnants, some of the planet's earliest evidence of life.
Therefore, 3.8 billion years ago, near the conclusion of this phase known as the late heavy bombardment, life on Earth first emerged, hence option A is correct.
