Answer:
three evolutionary lines
Explanation:
The Hox genes are master developmental genes found in animals, which are involved in the regulation of development by specifying the body plan of an embryo along the head-tail axis. Recently, several research groups studied the assortment of the Hox genes in three different marine organisms: 1- a priapulid worm (an unsegmented marine worm), 2- a brachiopod (phylum Brachiopoda), and 3- a polychaete worm (related to earthworms). Then, these research groups combined their research efforts to compare the assortment of the Hox genes observed in these species to those observed in previously studied animals including, among others, mice, fruit flies and sea urchins. From this combined study, researchers concluded that the animal kingdom can be divided into three primary evolutionary lineages.
A large population of wildcats is broken up into several small groups as a result of geogrpahic isolation over a long period of time these groups will most likely become
Answer:
The correct answer is - reproductively isolated.
Explanation:
Reproductively isolated organisms are the organisms that are occurred due to the split in two or more small groups as a result of geographical isolation over a longer time period from a single large group by process of natural evolution.
In the given case of wildcats which is splits into several small groups due to geographical isolation over a long period of time these groups of wildcats become reproductively isolated.
What are some future treatments that are on the horizon?it about Cancer
Answer:
New discoveries in the treatment of cancer do not only centre on conventional medicine. In our haste to get to grips with a cure for cancer, natural products may be overlooked and dismissed in the fight against such an aggressive disease.
In December, the Academy of General Dentistry reported that a new study had found that simply swishing green tea around the mouth halts the growth of new oral cancer cells and breaks down and kills existing oral cancer cells. The antioxidants (polyphenols) in the tea work to remove the free radicals or oxidants and prevent gene mutations, and as an added bonus, the polyphenols can kill cancerous cells without harming normal cells and inhibiting their growth. Similarly, a chemical found in tomatoes may prevent or treat oral cancer and one derived from soybeans has been found to shrink abnormal growths that lead to cancer. While these are not cures, their activity may in the future lead to therapies that compliment conventional treatment modalities.
Perhaps combining ancient remedies with Western scientific advances is the way forward to finding an effective cure for cancer. Combrestatin – a cancer-fighting drug made from the bark of an African tree – is performing with dramatic effects in tests. The active ingredient extracted from the bark attacks the blood vessels that grow with tumors, while leaving normal blood vessels alone.

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.

Body fat is used as a source of energy when not enough energy is available from food. This process involves:
Answer:
Fats typically provide more than half of the body's energy needs. Fat from food is broken down into fatty acids, which can travel in the blood and be captured by hungry cells. Fatty acids that aren't needed right away are packaged in bundles called triglycerides and stored in fat cells, which have unlimited capacity.

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).

Answer:
Biology is the science that studies life, but what exactly is life? This may sound like a silly question with an obvious response, but it is not always easy to define life. For example, a branch of biology called virology studies viruses, which exhibit some of the characteristics of living entities but lack others. It turns out that although viruses can attack living organisms, cause diseases, and even reproduce, they do not meet the criteria that biologists use to define life. Consequently, virologists are not biologists, strictly speaking. Similarly, some biologists study the early molecular evolution that gave rise to life; since the events that preceded life are not biological events, these scientists are also excluded from biology in the strict sense of the term.

What type of carbohydrates does Class Trix cereal contain?
Answer:
Trix cereal contains simple carbohydrates, which differ from complex carbohydrates in that they are easier for the body to break down. However, this is not necessarily a good thing. Simple carbohydrates are often too easy for the body to break down, resulting in a boost of energy, then a sugar crash. Try something like an apple or a banana instead, for a good source of complex carbs.
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.

A plane is traveling at 80 m/s. To prepare for landing, it decreases its speed to 50 m/s in 120 s.
Calculate the deceleration of the plane.
Answer:
The deceleration of the plane is 0.25 m/[tex]s^{2}[/tex].
Explanation:
Deceleration is the converse of acceleration.
From first law of motion, we have;
v = u + at
where: v is the final velocity, u is the initial velocity, a is the acceleration and t is the time taken.
Thus,
v = 50 m/s
u = 80 m/s
t = 120 s
50 = 80 + 120a
50 - 80 = 120a
-30 = 120a
a = [tex]\frac{-30}{120}[/tex]
= -0.25
a = -0.25 m/[tex]s^{2}[/tex]
The deceleration of the plane is 0.25 m/[tex]s^{2}[/tex].
