A person in a dark room looking through a window can clearly see a person outside in the day light . But a person outside cannot see the person inside
Explanation:
The explanation for this is that the space outside is illuminated with light from the sun. The person inside has either a lesser or no illumination at all. The dark inside room appears dark, and darkens the surface of the window facing inside, making it act like the silvered surface of a mirror. When the outside observer looks at the window, the window acts as a mirror, reflecting the light from the sun onto the eyes of the outside observer. For the inside observer, some of the illumination from outside finds its way inside, since the outside window surface is well lit, carrying with it the sensation of vision onto the eyes of the inside observer.

Answer:
Las hormonas activan vías de señalización celular, con lo cual regulando el crecimiento, metabolismo y reproducción del organismo
Explanation:
Las hormonas son moléculas mensajeras que circulan a través del torrente sanguíneo para llevar a cabo diferentes funciones. Estas moléculas se unen a receptores específicos presentes en la superficie de las células con la finalidad de controlar diferentes aspectos de su funcionamiento. Las hormonas son principalmente producidas por glándulas endocrinas pero también pueden ser secretadas por células intersticiales y epiteliales.
Las hormonas se dividen cinco clases principales:
a- pequeños neurotransmisores implicados en el funcionamiento del sistema nervioso (gonadotropina, somatostatina)

Smurfs live in widely separated groups and rarely interbreed, so geneticists know very little about them. On one occasion, two smurfs from different groups did mate. A big-footed, white smurf mated with a small-footed, blue smurf. Three offspring resulted: one big-footed and blue and two small-footed and blue.Which statement about the inheritance of color in smurfs is most likely to be correct?
Answer:
See the answer below
Explanation:
The most correct statement would be that the blue color is dominant over the white color.
According to Mendelian law, when there are two different versions of the same gene/trait in which one is dominant and the other is recessive, the dominant version will be expressed while the recessive version only stays in the background.
In this case, the alternate versions of the same trait in the smurf are the white and blue colors. When they are mixed together in the offspring, the blue color is expressed and the white color stays in the background. It means the blue color is dominant over the white color.

Answer:
DNA is consist of two strands that are coiled together to form a double helix structure in which both the strands are anti-parallel. The direction of one strand is from 5' to 3' and the other has 3' to 5'.
DNA is made up of nucleotide, phosphate group and deoxyribose sugar. The two anti-parallel strands on DNA are composed of nucleotide and bonded with hydrogen bond. There are four nitrogenous bases present in each nucleotide e adenine (A), guanine (G), Thymine (T) and cytosine (C). Where A and T are bonded with double hydrogen bond and G and C are bonded with triple hydrogen bond present complementary to each other in both the strands.
sugar -phophate group forms the backbone of the DNA.

After getting the slide and microscope ready, Stella is eager to see the microscopic pond water specimen! She crouches around her microscope and aligns her eye with the microscope’s eyepiece. But she's only able to see a bright white light. At this point, no specimens or cells are visible on Stella's pond water slide. After taking a moment to collect her thoughts, Stella realizes she can't see any lifeforms because a.the microscope is not yet in focus b.the microscope is not plugged in c.there are no specimens on the slide d.she hasn't fastened the slide to the stage
Answer:
she hasn't fastened the slide to the stage
Explanation:
In Microscopy even if the slide is not yet in focus,she will be able to see part of the slide which may appear as transparent image.Therefore this is a wrong answer.
If the microscope is not plugged it light can not come up.
If there are no specimen on the slide,the slide will still as transparent image at the focus.
No doubt Stella forgot to fasten the slide to the stage.,therefore the specimen on the slide was not in focus of the objective lens,rather she was focusing on the stage only,hence the visible white light.
Students make these mistakes in microscopy,they sometimes place the slide on the stage,but forget to fasten the stage clip,thus the slide is not in focus of the incident light,which gives no reflection to the viewer's eyes.
Energy is released from ATP when every phosphate bond is broken. the last phosphate bond is broken. all three phosphate bonds are formed. the last phosphate bond is formed.
Answer:
the last phosphate bond is broken
Explanation:
ATP, is a chemical molecule with the name, Adenosine triphosphate. It is the energy currency of a living cell usd to drive many cellular processes in the body. ATP is produced during the process of cellular respiration.
Adenosine triphosphate (ATP) has an Adenosine molecule (Adenine base and a ribose sugar) and three phosphate groups. However, the energy in ATP is harnessed for utilization when the bond that binds the third phosphate group is broken.
The breaking of the last phosphate bond releases a phosphate group and an Adenosine diphosphate (ADP) molecule.

Based on your model, do you think frogs reproduce sexually or asexually? What are the benefits and drawbacks to this
form of reproduction?
Answer:
Frogs reproducesexually and when organisisms reproduce sexually there are benefits which include:
produces genetic variation in the offspring.
the species can adapt to new environments due to variation, which gives them a survival advantage.
a disease is less likely to affect all the individuals in a population.
A disadvantage is that sexual reproduction takes longer than asexual reproduction. A mate must be found, the egg must be fertilised by sperm, and then the offspring develop. The benefit of introducing genetic variation into the species , however, outweighs this disadvantage.
Answer:
Frogs reproduce sexually: they require sperm from a male and an egg from a female to produce offspring. This type of reproduction allows for greater genetic variation. But organisms that sexually reproduce need to reach sexual maturity before they can reproduce. They also use energy to find a mate.

Which best explains a primary reason for the inability of life to exist in Earth’s early atmosphere? There was insufficient energy from material collisions to change their density. High temperatures during Precambrian time caused surface water evaporation. Volcanic eruptions and comet collisions added different gases to the atmosphere. Available oxygen was used to help create an ozone layer within Earth’s atmosphere.
Answer:
c
Explanation:
on edge
The sentence that best explains the primary reason for the inability of life to exist in Earth’s early atmosphere is " Volcanic eruptions and comet collisions added different gases to the atmosphere".
During the early years of the Earth volcanic eruptions were much more common than they are today. When these volcanoes erupted, they spewed many gases into the atmosphere, including:
Carbon dioxideWater vaporNitrogenHydrogenwhich was directly responsible for the composition of the early atmosphere.
Due to these gases being released into the atmosphere by Volcanic eruptions, causing a severe lack of oxygen, life on Earth was almost unsustainable. It was not until solar radiation and photosynthesis produced oxygen that life became sustainable.
