Answer:
cerebral cortex, which is greatly expanded in nonhuman primates and cetaceans
Explanation:
The cerebral cortex, also known as the cerebral mantle (or gray matter), is the outermost layer of the brain in primates and other mammals. The cerebral cortex contains up to six layers of nerve cells and consists of approximately 15 billion neurons. This highly developed structure (cerebral cortex) is located in the forebrain, where is responsible for several complex functions including language and thinking processes.
A garden pea plant possesses one allele coded for yellow seed colour and one a coded for green seed colour. Which statement is true?
Answers
A green pea plant possesses one allele coded for yellow seed color and one a coded for green seed color. The true statement is the individual is heterozygous for the seed-color allele.
What are alleles?At a given genomic location, an allele is one of two or more variants of DNA sequence (a mono base or a segment of bases).
For any given genomic location where such variation exists, an individual inherits two alleles, one from each parent. If both alleles are identical, the person is similar for that allele.
Thus, the true statement is the individual is heterozygous for the seed-color allele.

How long does it take for the daughter cells from one round of replication to replicate themselves?
No time is required -- they are ready to divide immediately after DNA replication and separation of the daughter cells is complete if conditions are right.
20 minutes
After the cells have matured fully.
No time is needed -- the daughter cells cannot replicate further.
Answers
The daughter cells from one round of replication are ready to divide immediately after DNA replication and separation is complete, provided that the conditions are favorable. This means that no time is required for them to start the replication process.
Once the daughter cells have divided, they begin their own replication process, which takes approximately 20 minutes. During this time, the cell undergoes a series of complex processes to create a copy of its DNA. The replication process involves the unwinding of DNA strands, the synthesis of new DNA strands, and the joining of the newly synthesized strands to the original template. Once this process is complete, the daughter cells are ready to divide again, and the cycle continues.
It's important to note that the time it takes for daughter cells to replicate themselves can vary depending on the type of cell and the conditions it's in. However, in general, the replication process takes around 20 minutes to complete.

. Explain how the polarity of water is a major factor that
controls the rate of infiltration in soils. 300 words
Answers
The polarity of water is a major factor that controls the rate of infiltration in soils. This phenomenon is primarily attributed to the unique properties of water molecules and their interactions with soil particles.
Water is a polar molecule, meaning it has a slight positive charge at one end (hydrogen) and a slight negative charge at the other end (oxygen). This polarity arises due to the unequal sharing of electrons between hydrogen and oxygen atoms within the molecule. As a result, water molecules exhibit an electric dipole, with the oxygen side being more electronegative and the hydrogen side being more electropositive.
When water comes into contact with soil particles, which may be composed of minerals or organic matter, the polarity of water plays a crucial role in infiltration. The surface of most soil particles carries a net negative charge (known as a negative surface charge). These charged particles attract the positively charged hydrogen ends of water molecules through electrostatic forces.
This attraction between water molecules and soil particles helps to overcome the force of gravity acting against infiltration. Water molecules bind to the soil particles and create a thin film of water around them. This process is known as adsorption. The adsorbed water molecules create a bridge between soil particles, reducing the friction between them and facilitating further infiltration.
Moreover, the polarity of water also contributes to its cohesive and adhesive properties. Cohesion refers to the tendency of water molecules to stick together, while adhesion refers to the ability of water molecules to adhere to other surfaces. These properties allow water to form continuous columns or chains, enhancing its movement through soil pores and facilitating infiltration.
Additionally, the polarity of water enables it to dissolve various substances. Soil particles often contain ions, organic compounds, and nutrients that are essential for plant growth. Water's ability to dissolve and transport these solutes further aids in nutrient uptake by plants during infiltration.
In summary, the polarity of water is a critical factor influencing the rate of infiltration in soils. Its ability to form hydrogen bonds with soil particles, reduce friction, and facilitate the movement of water through soil pores is essential for efficient water infiltration and nutrient transport in terrestrial ecosystems.

Index fossils are usually defined as those fossils that were present on earth for a very short period of time. They were very broadly distributed in almost all parts of the world. They were comparatively smaller in size and comprised of hard parts that were preserved under favorable conditions which are found at many places in the present. These are extinct species. For example, trilobites and ammonites.
These index fossils are very useful because it helps in determining the age of the fossils as well as rocks by applying the radioactive dating method.
