What is the best definition of a chromosome? Based on the picture provided above :)
Answer:
d.
Explanation:
A chromosome is a strand of DNA that is encoded with genes. In most cells, humans have 22 pairs of these chromosomes plus the two sex chromosomes (XX in females and XY in males) for a total of 46. The word chromosome was originally coined in German from the Greek words khroma, meaning color, and soma meaning body.
Which is the best evidence that two species have a common ancestor?
A:The two species have the same diet.
B:The two species live in the same habitat.
C:The two species' skeletal structures are 90% identical.
D:The two species' DNA sequences are 90% identical.
Answer:
I'd go with D.
Explanation:
Species may share similar physical features because the feature was present in a common ancestor (homologous structures). Molecular biology. DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are.
The respiratory system is divided into two parts a) Air passage way b) The lungs
Please explain Air passage way.
Explanation:
The air passage way is connected to the through the main organ/thing is called the trachea. When you breathe in oxygen in order to get to the lungs air goes through the throat and your trachea. Same goes for when you breathe out carbon dioxide.
Answer:
From the nostril we get to the tubulates which leads to the nasopharynx from there it leads to the glotis and way down gets to the trachea from where it to the bronchi and finally branches to the bronchus.

It is directly gaining energy from the mous because the mouse is what gives the snake energy and if the snake directly consume it, it will get energy from it.
In organ transplants, the body recognizes that the new organ is made of foreign cells. What kind of medicine would you give a patient to increase the chances of transplant success?
Answer:
immunosuppressant
Explanation:
After an organ transplant, you will need to take immunosuppressant (anti-rejection) drugs. These drugs help prevent your immune system from attacking ("rejecting") the donor organ. Typically, they must be taken for the lifetime of your transplanted organ.
All cells reproduce to make new cells. However, stem cells actually form many different types of cells. Adult stem cells can also repair tissues in the body.

Cuya función es extender el mucus y dirigirlo hacia el exterior. En el estómago, las glándulas digestivas producen el ... El cual, por su extremada ... Ataca y destruye a los ... Que se introducen con la comida y la bebida.
Answer:
The respiratory system has cells that produce MOCO OR MUCUS, which trap germs and dust. On their surface they have a large number of cellular structures called CILIAS, whose function is to spread mucus and direct it outwards. In the stomach, the digestive glands produce the STOMACH ACID, which, due to its extreme ACIDITY, attacks and destroys the PATHOGEN MICROORGANISMS that are introduced with food and drink.
Explanation:
In the respiratory and digestive apparatus there are two types of super specialized mucous upholstery, where the cellular world is challenged.
In the respiratory mucosa the production of mucus and the mobilization of the cilia are part of the innate response of the organism as well as the acidity that is generated in the upholstery and in the gastric tract.

Answer:3 or c
Explanation:
i really need help on this one, A,B or C.
Answer:
B
Explanation:
B makes the most sense of your answer choices
Answer:
A)
Explanation:
This is because the law of the conservation of energy states that energy can not be created or destroyed. This means that you can not get more energy than you put in, this could be from any energy store. In addition That also means that you will not be able to get less energy than you put in.
Although energy can not be created or destroyed some energy is lost to heat or friction, this would mean that the energy is not transferred to the idea store and so is lost to inefficiency . An example of this would be wind turbines, the wind would move the turbine using kinetic energy however some of the energy is lost to heat and friction
You are a geneticist and two very angry hobbits, Pippin and Lola, come storming into your office. Pippin and Lola have just had a newborn baby girl named Beatrice. Beatrice has blue eyes, but pippin and Lola both have green eyes. Green eyes are dominant over blue eyes. Pippin thinks that Beatrice is not his baby, and is very angry with lola. Determine how it is in fact possible for Beatrice to be pippins baby girl.
A) What are pippin and Lola's genotype?
B) What is Beatrice's genotype?
Answer:
A.) If "G" is the dominant green-eyed gene and "g" is the blue-eyed gene, then Pippin and Lola's genotypes will both be Gg.
B.) Beatrice's genotype is gg.

Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.
Explanation:
Explain how the digestive and circulatory systems interact.
Answer:
Explanation:
Both systems interact in the sense that digestive system involves the breaking down of complex food substances into simpler absorbable forms. These absorbable forms like glucose , amino acids etc are assimilated into the circulatory system through the hair-like structures in the small intestine (Villi, which has lots of blood capillaries) into the circulatory system. The circulatory system transports these food materials to different parts of the body where they are need for energy production and other metabolic activities.

The Seven Sisters are seven stars located more than 400 light-years away in the Taurus constellation and they can be seen here with Venus and another constellation, Orion. Why do these stars seem so small compared to our Sun, also a star?
A) Our Sun is much larger than any of the Seven Sisters.
B) Our Sun is much closer to Earth than the Seven Sisters.
C) The Seven Sisters are ancient stars; the Sun is a young star.
D) Stars found in constellations are much older and smaller than any other stars.
Answer:
The reason why these stars seem so small compared to our Sun is:
B) Our Sun is much closer to Earth than the Seven Sisters.
Explanation:
The reason behind this is that the sun is at a distance of the earth of 0.000016004 light-years. While the seven stars are at a distance of 400 light-years. Making them so far away that their size is reduced because in physics object size is altered by the perspective of the watcher or observer. Meaning that a ball the size of a car can be seen by our eyes as small as a bean if it is at the proper distance.

In a certain state, electricity is generated by using the earths heat. Wells drilled and natural steam is taken out through pipes. This natural steam powers the generator and the electricity generated. What type of energy is being used and what type of power plants are set up for harnessing this renewable energy?
Answer:
Geothermal
Explanation:
The geothermal energy is generated by the Earth's core that is a region with extremely high temperatures. The heat makes the geothermal power plants to work and thus generate energy from it.
In ancient times, why would a cloudy day make it so hard to tell what time it is?
Answer:
Because celestial bodies such as the sun and stars were used to tell time, so if they were obstructed by clouds it would be hard to tell time

Succession in ecology is the gradual encroachment of life on a given ecosystem.
Primary succession involve a new never-before colonized region like a new lava deposit or land hidden under glacial sheets. Secondary succession is the encroachment of life on an area formerly harboring life but had experience a disturbance like wildfire, agricultural activities, logging etc.
Answer:
PRIMARY SUCCESSION (recently cooled lava field) and (rocky hill under a melted glacier). SECONDARY SUCCESSION (vacant parking lot for many years) (abandoned baseball field) and (clear-cut forest.
