Scientists use existing fossils to predict what the transitional forms between organisms might look like. Why might it be so hard for scientists to find fossils of these transitional forms
Answer:
Any preserved remains, trace, or impression of any once-thriving living thing from the past geological age is known as a fossil. This comprises exoskeletons, bones, stone imprints of animals or microbes, shells, hair, petrified wood, objects preserved in amber, DNA remnants, coal, and oil. The fossil record is the term used for the totality of fossils.
The scientists use the prevailing fossils to show what the intermediary forms between the organisms may appear like. It is hard for the scientists to locate the fossils of the transitional forms as the formation of the fossils of the transitional forms may have never taken place because of the environmental conditions. In case if they did have formed, then the natural procedures like erosion may have demolished them.

A virus that can be transmitted through arthropods such as ticks, flies, and mosquitoes is considered an arbovirus.
2. Some arboviruses can move through the bloodstream and infect the brains of human and animal arboviruses. This manifestation of the disease is called encephalitis.
Explanation:
Arboviruses are very dangerous for humans, some do not generate painful bites, others are hematofogous (they feed on human blood) and others are nocturnal, which bite humans at night without their perceiving it.
Diseases of these viruses that are transmitted by vectors such as arthropods cause encephalitis, cardiac, pulmonary disorders, etc.
An example of this is the Chagas disease that is generated by the transmission of the Vinchuca arthropod.
narrowing of the coronary arteries due to buildup of debris along the artery
Answer:
The correct answer is coronary artery disease.
Explanation:
The narrowing of blockage of the coronary arteries, generally resulting due to atherosclerosis is known as coronary artery disease. Atherosclerosis also is known as the clogging or hardening of the arteries and is the accumulation of fatty deposits and cholesterol on the artery's inner walls.
These fatty deposits of plaques can prevent the flow of the blood to the muscles of the heart by physically choking the artery or by resulting in unusual artery function and tone. In the absence of a sufficient supply of blood, the heart becomes deficient of the essential nutrients and oxygen it requires to function appropriately. This can further result in angina or chest pain.

Which mode of genetic recombination is matched correctly with its description? transduction—virus transfers genes from one bacteria to another conjugation—involves splitting of one cell and results in two identical cells binary fission—requires direct cell-to-cell contact of bacteria transformation—uses a pilus to transmit genetic information between bacteria
Answer:
transduction—virus transfers genes from one bacteria to another
Explanation:
Transduction is a mechanism of recombination where DNA fragments are inserted into bacteria by a viral vector. The mechanism of transduction is commonly used by molecular biology laboratories to insert gene fragments into both bacterial and mammalian cells.
Conjugation is the genetic mechanism in which bacteria transfer genetic information among them by direct contact.
Binary fission is the most common type of asexual reproduction in bacteria. In binary fission, the DNA molecule is replicated and, subsequently, the bacterial cell is divided into two daughter cells with identical genetic material.
Finally, the transformation is the mechanism of horizontal gene transfer in which one bacterium takes up genetic information into the surrounding environment and incorporates it into its genome.

Donor Blood Type Recipient Blood Type A- Successful
A+ A-
O- AB+
Would the above two transfusions be successful or would either of them harm the recipient? For each transfusion, explain your reasoning. In your explanations, use the following terms: antigen, antibodies, and agglutination.
Answer:
The first blood transfusion in which the donor blood type is A+ and recipient blood type is A- would not be successful as the donor blood is A+, which signifies that the blood comprises both Rh factor and antigen A, while the recipient blood group is A-, which signifies that the blood does not comprise Rh factor and possess only antigen A. Therefore, at the time of transfusion, the Rh factor of donor blood will be regarded as a foreign body by the recipient, and thus, will generate antibody against the donor Rh factor provoking immune rejection and agglutination.
On the other hand, the second blood transfusion in which the donor blood type is O- and the recipient blood type is AB+, the blood transfusion would be successful as the blood group O- is a universal donor, as it neither possesses any A or B antigen nor Rh factor. This blood group is accepted by all the blood group recipients.

8. Steroidal hormones enter the cell directly and interact with DNA inside the nucleus. These hormones change gene expression, affecting the RNA that is produced and the proteins that are translated in a cell. Nonsteroid hormones do not enter the cell. Instead, they bind to specific receptors on the outside of the cell membrane. This triggers molecules called secondary messengers, such as cAMP, to begin their work of relaying information in the cell, where other chemicals, messengers, and proteins are involved to create a cellular response.

The genomic DNA of an organism has a base composition of 40% C-G base pairs and 60% A-T base pairs. Assuming a random sequence of bases, what is the expected frequency of the Tsp E1 restriction sites 5'-CCGG-3'?
Answer:
The correct answer is (0.2)^4.
Explanation:
Based on the given information, the given genomic DNA is A-T rich, and the base pair composition is C-G = 40 % and A-T = 60%. Therefore, as per Chargaff's rule, Each C and G will possess 20%, and each A and T will possess 30%.
Therefore, the probability of each base will be,
C = 20/100 = 0.2
G = 20/100 = 0.2
A = 30/100 = 0.3
T = 30/100 = 0.3
Now the expected frequency of the Tsp E1 restriction sites 5'-CCGG-3' will be 0.2 * 0.2 * 0.2 * 0.2 = (0.2)^4.

How does increasing the distance between charged objects affect the electric force between them?
O The electric force increases because the distance has an indirect relationship to the force.
The electric force increases because the distance has a direct relationship to the force.
O The electric force decreases because the distance has an indirect relationship to the force.
O The electric force decreases because the distance has a direct relationship to the force.
Answer:
C. The electric force decreases because the distance has an indirect relationship to the force.
Explanation:
The electric force decreases because the distance has an indirect relationship to the force. Therefore, the correct statement is option C.
What happens when the distance between two charged items grows?As the distance between two charged items grows, the electric force between them diminishes. Because of the inverse square law, which states that the force of attraction or repulsion between two charged objects diminishes as the square of the distance between them rises, this is the case.
The force exerted by two charged objects will be decreased to one-fourth of its initial strength if the distance between them doubles. Similar to this, if the distance is quadrupled, the force loses 90 percent of its initial power. As a result, the electric force between charged objects lessens with increasing distance.
The farther the distance between charged objects, the weaker the electric force between them becomes due to the decrease in the strength of the electric field. This relationship follows an inverse square law.
Therefore, electric force decreases because the distance has an indirect relationship to the force.

describe the process involved when the human eye views an object
Answer:
How the eye view an object.
As the object appear before the eye,
Light enter the cornea, the domeshape that cover the front eye.
The light then enter the pupil through the cornea.
The light then hit the eye lens, a transparent structure that focuses the light through the virteous humour, a gel like substance that surrond the retina.
The retina then receive the light that was focused by the eyes lens and transform it to electrical impulses.
The electrical impulses is then transmitted to the person through the optic nerve,
The optic nerve then interpret it as the object view.
Explanation.
Eyes are organs of the visual system. They provide both humans and animals with the ability to receive and process visual information, thereby enabling different photo response functions that are independent of vision. Eyes detect light and convert it to electrical impulses in neurons. The optic nerve then send it to the brain which is then is interpreted as what is seen.
