Which of the following features did whales possibly inherit from a four-legged ancestor?
1. gills
2. hip bones
3. blow hole
4. dorsal fin
Answer:
2. Hip bones
Explanation:
More than 40 million years ago, whales had ancestors who walked on land. Even now, they have a feature they inherited from them - hip bones. Scientists used to think that they are vestigial, i.e. that they lost their function. However, recently they discovered that these bones help whales (and other marine mammals who have them, such as dolphins) maneuver better mating.
Whales developed the rest of the listed features later, when they became marine animals. This is why they are incorrect.

what is animal?why they are animal?
Answer:
The word "animal" comes from the Latin animalis, meaning having breath, having soul or living being. The biological definition includes all members of the kingdom Animalia. In colloquial usage, as a consequence of anthropocentrism, the term animal is sometimes used nonscientifically to refer only to non-human animals.

animals are the most advanced organisms onthe planet. They are animals because they cannot work like us humans and are not having big brains like us.

What determines if a particle can cross a cell membrane? *
Answer:
Lipophilic (non-polar molecules), such as steroid hormones or O2 gas can pass... very small uncharged polar molecules (such as H2O, ethanol and urea) can also get through... otherwise you need a membrane protein to "facilitate" the transport of the molecule across the membrane, ion channels are used for water, or charged molecules; carriers/transporters are used for other molecules.

Answer: No
Explanation: Type B is not possible if there are AA parents. The child could have A or O blood if both their parents are type A. Type B is only possible, not certain though, when parents are A and B. If parents are A and B, the child could be A, B, AB, or O.
A baseball league considers changing the rules to use a ball with a much greater mass. What effect would this have on the flight of the ball?
Answer: The ball, if thrown with the same instantaneous acceleration, and same sngle of release, would have a shorter flight time and have dropped less.
Explanation: A heavier ball could be harder to throw. It might also have a larger volume. The flight of the ball would depend on the force applied and the mass of the ball and air resistance. Suppose that the same force is applied to the standard and heavy balls, which differ in density but not volume. As they are thrown over the same distance, the drop due to gravity will depend on the time taken to the batter, which will depend on the average velocity.
Provided the mass of the ball is still within the range where maximum force can be applied by the pitcher, the initial velocity will be much the same.
Momentum, however is proportional to mass. The larger mass, all else held constant, will be decelerated more slowly by air resistance, and will arrive at the batter more quickly. If the angle of delivery is the same, the heavier ball will arrive higher because flight time was less.
The ball would arrive at the batter with more kinetic energy and impact with the bat would be harder.

Which of the following statements best describes why the change in only one DNA base of a gene does not always result in a different protein being produced by the gene?
A. The change prevents mRNA from being made.
B. Some codons code for the same amino acid.
C. Some codons are translated from DNA.
D. The change creates an additional mRNA strand.
The statement which best describes why the change in only one deoxyribonucleic acid (DNA) base of a gene does not always result in a different protein being produced by the gene is: A. The change prevents mRNA from being made.
Deoxyribonucleotides refers to the fundamental (basic) unit of a deoxyribonucleic acid (DNA).
Basically, deoxyribonucleotides contains a nitrogenous base and phosphate group that is referred to as deoxyribose sugar.
On a related note, the nitrogenous base of deoxyribonucleotides includes the following components:
Adenine (A).Guanine (G).Cytosine (C).Thymine (T).Gene expression simply means the transcription of a gene into a messenger ribonucleic acid (mRNA), as well as its subsequent translation into protein.
In Genetics, the genes that are present in deoxyribonucleic acid (DNA) are mainly responsible for encoding protein molecules.
However, a change in a single deoxyribonucleic acid (DNA) base of a gene doesn't always result in the production of a different protein by the gene because the change prevents messenger RNA (mRNA) from being made.

Synonym codons code a single amino acid. In consequence, 'some codons code for the same amino acid' indicates why a change in one DNA base of a gene does not always result in a different protein (Option B).
During gene transcription, a single-stranded fragment of DNA is used as template to create a complementary messenger RNA (mRNA) sequence.Subsequently, this mRNA sequence is then used as template to create a polypeptide (i.e., a protein) by a process called translation. The triplets of nucleotides or 'codons' in the mRNA sequence determine a specific amino acid that will be added to the polypeptide chain.There are 64 codons: 61 codons represent only 20 amino acids, while the remaining three (3) are stop codons that determine the end of translation.Thus, the genetic code is said to be redundant because there are different codons that encode the same amino acid. These codons are called synonymous codons.For example, phenylalanine is an amino acid residue that can be specified by two different codons (UUU and UUC).In conclusion, the statement 'some codons code for the same amino acid' BEST describes why the change in one DNA base of a gene does not always result in a different protein (Option B).

Given sin 0 = 4/5
use the Pythagorean Theorem to find the value of cos 0.
A) cos 0 = 3/4
B) cos 0 = 3/5
C) cos 0 = 4/3
D) cos 0 = 4/5
Answer:
cosθ = 3/5
Explanation:
Given that,
sinθ = 4/5
We need to find the value of cosθ.
We know that,
sinθ = P/H
Where
P is perpendicular and H is Hypotenuse
Using Pythagoras theorem to find base (b).
H²=P²+B², b is base
We have, H = 5, P = 4, B=?
b²=5²-4²
b=3
We know that, cosθ = B/H
Putting all the values,
cosθ = 3/5
Hence, the correct option is (b) "cosθ = 3/5".
Diffusion continues until what is reached ?
Answer:
Diffusion will continue until the concentration gradient has been eliminated. Since diffusion moves materials from an area of higher concentration to the lower, it is described as moving solutes "down the concentration gradient." The end result of diffusion is an equal concentration, or equilibrium, of molecules on both sides of the membrane. At equilibrium, movement of molecules does not stop. At equilibrium, there is equal movement of materials in both directions.

Some scientists are studying the bacteria that live in the guts of termites because those bacteria may contain genes that help convert plant material to ethanol.
What are termites?Termites are a type of insect that belongs to the order Isoptera. They are commonly known as white ants but they are not closely related to true ants. They are social insects and live in colonies or nests.
Termites are able to break down the cellulose in wood and other plant materials, which is a process that has potential applications in biofuel production. The bacteria that live in the termites' gut play an important role in this process by producing enzymes that help to break down the cellulose. Scientists are interested in studying these bacteria to learn more about the enzymes they produce and how they can be used to convert plant material into ethanol more efficiently.
