According to the scenario option, "4" is correct that It is a transitional fossil that shows correlation.
What is a transitional fossil and why is it important?A transitional fossil is described as a fossil that shows traits common to both ancestral and derived groups.
This is specifically significant when groups are sharply differentiated. They can show how a species might adapt to survive their new circumstances.
Thus, It is a transitional fossil that shows correlation.

1. Describe the classical scheme of gene expression from DNA to RNA to protein.
2. Explain DNA replication and recombination.
Answer:
1. The central dogma of molecular biology is DNA >>transcription>> RNA >>translation>> protein
2. DNA replication refers to the genetic process of generating two identical DNA molecules from one DNA sequence. Recombination refers to the exchange of genetic material (DNA) between non-sister chromatids during cell division (meiosis)
Explanation:
Gene expression (also known as transcription) is the process by which a specific fragment of DNA called gene is used as template to synthesize an RNA molecule, usually a messenger RNA (mRNA), which is in turn used as template to create a protein. This final product (i.e., the protein) has an effect on the phenotype of the individual. The DNA template is a single-stranded ordered polynucleotide chain composed of four different types of nitrogenous bases: Adenine, Thymine, Guanine and Cytosine. In the complementary RNA molecule, Thymine bases are replaced by Uracil bases. Moreover, DNA replication refers to the process by which cells duplicate their genetic material before cell division (either mitosis or meiosis). During this process, both DNA strands are separated and each one is used as a template to synthesize a new DNA molecule. Finally, recombination or crossing over is a process where non-sister chromatids exchange genetic material during meiosis I (Prophase I). Recombination is known to increase genetic variation in resulting meiotic cells.

What effect would building a highway have on an ecosystem?
A) increase in butterfly migration
B) Decrease in destruction of a habitat
C) Increase in carbon dioxide
D) Increase in oxygen
Answer:
C
Explanation:
Building a highway destroys an ecosystem/habitat, so not b. With the ecosystem destroyed there will be a reduced number of trees that produce oxygen, so not d. Now you make an educated guess. If there is a large highway there will be a lot of cars which produce lots of carbon dioxide. No butterflies.

How to use informal assessment effectively to prepare for examination
Answer:
Kindly check explanation
Explanation:
The use of informal assessment while preparing for an examination could take various forms. Informal assessment include the use of actual grading of a set of questions which one decides to test his/her knowledge on in other to check or evaluate performance. Similarly, one may employ the use of a colleague or friend to set out a few likely questions from the subject or the use of previous test or examination questions to ascertain how well one has grasped or covered in the subject. Also, one could personally reminisce on the areas covered, frame likely questions in reasoning and check if the appropriate response could be proffered.
Which structure in the heart'separates
oxygenated blood from deoxygenated blood?
Answer:
pericardium
Explanation:
A double-walled membrane, the pericardium, separates the right and left chambers, preventing oxygen-rich blood from mixing up with the one without oxygen. So, the heart functions go smoothly. Deoxygenated blood enters the right atrium.

Explain why short bursts of light during the dark period caused the Xanthium strumarium plant to not grow.
Answer:
Due to stoppage of reactions.
Explanation:
The short bursts of light during the dark period is responsible for no growth in the Xanthium strumarium plant because this short bursts of light affected the darkness which is required by the Xanthium strumarium plant for its growth. If there is no burst of light occurs, the Xanthium strumarium plant will grow normally but when Xanthium strumarium plant receives the bursts of light, the chemical reactions that needs darkness will stop and as a result no growth occurs.

The brachial plexus is associated with which of the following?
A. Innervation of the upper limbs
B.Innervation of the lower limbs
C.Axillary nerve is a terminal branch
D. A and B are correct
E. A and Care correct
Answer:
innervation of the upper limbs
The brachial plexus is a nerve network located at the base of the neck and the axillary fossa associated with sensory and motor innervation for the entire upper limb.
What is the brachial plexus?It is responsible for providing the motor (muscle), sensory and sympathetic innervation of the upper limb.
Through it, the spinal cord is connected with all the peripheral nerves of the upper limbs and all the sensorimotor information of these segments is also transmitted.
Therefore, we can conclude that the brachial plexus is a nerve network located at the base of the neck and the axillary fossa associated with sensory and motor innervation for the entire upper limb.

What human behavior was the cause of the Nipah virus outbreak in Bangladesh? How did scientists determine this?
Answer:
Humans drinking raw date palm sap was the cause of the Nipah virus outbreak in Bangladesh. Scientists found Nipah virus in bat excretions and discovered that bats were contaminating date palm juice with their excretions (saliva, urine).
Explanation:
Nipah virus can spread to people from:
1) Direct contact with infected animals, such as bats or pigs, or their body fluids (such as blood, urine or saliva).
2) Consuming food products that have been contaminated by body fluids of infected animals (such as palm sap or fruit contaminated by an infected bat).

DDDDDDDDDDDDDDDDDDDDDDDDDD
Answer:
The answer is C.
Explanation:
This is because for A, this statement says nothing about corundum being yellow which means that this doesn’t apply and is incorrect. For B is pretty much the same as A, this statement about corundum doesn’t say anything about it being able to flavor or being flavorful. Lastly for D, the fact that corundum is hard means it would be impractical and probably impossible to use it as pencil lead because, all lead it doing with a pencil is being crushes and ground into the paper as you write.
