Answer:
The frequency is higher in case of echolocation sounds produced by Bottlenose dolphins. It falls in the range 40,000 Hz to 130,000 Hz, while the calls made by blue whales lies in the range of 30 Hz to 8,000 Hz.
However, the blue whale calls last a lot longer than the echolocation sounds made by the dolphins. A typical blue whale call is between 10 to 30 seconds long, while the dolphin's click is only 50 to 128 microseconds long.

Describe natural selection
Answer:
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:
Is someone walking up to you from behind? A friend is walking up to you from behind. What three observations would help you predict when they would reach you?
Answer:
Three things i will observe are :
The sound of their movement when approaching meThe frequency of their foot stepThe distance they are away from meExplanation:
In my opinion, the three points highlighted above can go a long way to help predict how soon or when they would reach meThe sound of their foot steps will determine how far or close they are from from me, if the sound is loud they are closest, if it is low then they are at a distance father.The frequency of their foot steps tell me about the speed with which they are approaching me, if the frequency is high, then they will approach sooner and vice versaThe distance they are way from me can help estimate when they would reach me, though still dependent on items one and two above.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.

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.

When the total lunar eclipse occurs what are the relative positions of the sun earth and moon
Answer:
A lunar eclipse occurs when the Moon passes directly behind the Earth into its umbra (shadow). This can occur only when the sun, Earth and moon are aligned (in "syzygy") exactly, or very closely so, with the Earth in the middle.
Explanation:
Answer:
The earth is between the sun and the moon
Explanation:
The Moon is non luminous that is doesn't generate light by itself so it depends on light from the sun so when its path through which it taps light from the sun is totally covered it means the Earth is closer to the moon than the Sun so that the Earth gets all off its light leaving nothing for the Moon and in this case the Moon is thrown to total darkness.
Why do we need human dna
DNA. Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions for the development and function of living things.
All known cellular life and some viruses contain DNA. The main role of DNA in the cell is the long-term storage of information.
We need human DNA since it give us the long term info storage, which is needed
DNA contains instructions for development, survival, and reproduction. DNA sequences must be translated into signals to make proteins, which do most of our body's job.
What is human genome?DNA stores the instructions that are necessary for an organism to grow, maintain its existence, and reproduce itself. In order for these duties to be carried out, the sequences of DNA need to be transformed into messages that can be utilized in the production of proteins. Proteins are the complex molecules that are responsible for the majority of the work that is done in our bodies.
The human genome is comprised of all of the nucleic acid sequences that are found in humans. These sequences are stored as DNA within the 23 chromosome pairs that are found in the nucleus of cells, as well as in a tiny DNA molecule that is located within the mitochondria of each individual cell. In most cases, these are considered to be two distinct components: the nuclear genome and the mitochondrial genome.

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

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.
What is a “shared derived character”?
Answer:
A shared character is one that two lineages have in common, and a derived character is one that evolved in the lineage leading up to a clade and that sets members of that clade apart from other individuals.
Answer:
A shared character is one that two lineages have in common, and a derived character is one that evolved in the lineage leading up to a clade and that sets members of that clade apart from other individuals. Shared derived characters can be used to group organisms into clades. For example, amphibians, turtles, lizards, snakes, crocodiles, birds and mammals all have, or historically had, four limbs. If you look at a modern snake you might not see obvious limbs, but fossils show that ancient snakes did have limbs, and some modern snakes actually do retain rudimentary limbs. Four limbs is a shared derived character inherited from a common ancestor that helps set apart this particular clade of vertebrates.
