Answer:
No
Explanation:
A person having blood type B has either of the two genotypes
IbIb
OR
OIb
O represents the blood group B
The genotype of two parents is IaIa and IbIb
Gametes of IaIa are Ia, Ia
Gametes of IbIb are Ib, Ib
IaIa * IbIb
IaIb, IaIb, IaIb, IaIb
All the offspring have genotype AB
Hence two homozygous parents for Blood type A and B will not have any offspring with blood type B

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.
What is the best definition of a chromosome? Based on the picture provided above :)

Birds can regulate their body temperature, they are
(A) ectothermic
(B) endothermic
(C) mesleothermic
(D) hydroponic
Answer:
b
Explanation:
Birds are Endotherms since they generate more heat to control their body temperature and so unlike ectotherms, bird's regulating of body temperature is based on internal rather than external(environmental) factors.
. Why is the carpel considered female and the stamen male?
Answer: A carpel is the female reproductive part of the flower, interpreted as modified leaves that bear structures called ovules, inside which the egg cells ultimately form and composed of ovary, style and stigma. Stamen, the male reproductive part of a flower, consisting of a long slender stalk and the pollen-producing anther.
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

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.

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.
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.

Answer:
1) vacant parking lot for many years (secondary succession)
2) abandoned baseball field (secondary succession)
3) recently cooled lava field (primary succession)
4) rocky hill under a melted glacier (primary succession)
5) clear-cut forest (secondary succession)
Explanation:
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.

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.
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.

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.
