Answer:
Explanation:
Removing the nucleus takes away all the genetic information necessary for the function of the cell away. Prokaryotes although lacking a nucleus do have a Nucloid region containing Naked strands of DNA which regulate their activity.
Simply removing the nucleus from a eukaryotic cell would not turn it into a prokaryotic cell, as the two cell types differ in many aspects, including structure and replication methods.
Removing the nucleus from a cell would not result in a new prokaryotic cell. Prokaryotic cells, such as bacteria, do not merely lack a nucleus. They also differ from eukaryotic cells in many other ways. For example, prokaryotic cells typically have a simpler structure and lack many of the organelles found in eukaryotic cells, such as mitochondria, Golgi bodies, or endoplasmic reticulum. Furthermore, prokaryotic and eukaryotic cells replicate in different ways, with prokaryotes using a process called binary fission and eukaryotes using mitosis and meiosis.
Cellular structure and replication methods are crucial characteristics that distinguish the two types of cells, so the removal of just the nucleus would not be sufficient to create a prokaryotic cell from a eukaryotic one.

Redwoods
Answer: The correct answer is- b) Mosquitoes.
R- selected species are those species that can survive in unstable, unpredictable environmental conditions and produce large number of small size offspring. These offspring have low survival rate ( short life span) and do not have any parental care.
These species grow very rapidly and attain reproductive maturity at early stage in their lives.
Example of R- selected species- Insects ( such as mosquitoes), rats.
On the other hand, a) , c), and d) are K selected species. They survive under stable environmental conditions and produce large size offspring with very few number. They have long life span and experience parental care
Mosquitoes are an R-related species.
Further Explanation:
The fitness of a phenotype determines whether it gets naturally selected or not. For a condition where the environment of each year changes and the adaptability of the phenotypes are different for a different environment, the oscillating selection might occur in which different phenotypes are favored at different times and different environmental conditions.
Fitness can be attained by two different approaches, namely:
How much a system can invest in one approach at the cost of others depends on the environment. This type of selection is known as R-K selection. In K-selection, the organism matures slowly and has a long life span. In R-selection, the organism produces many copies of progeny in an unstable environment. Mosquito, mice, and rabbits are an example of R-species.
Some features of R-species are:

The correct answer is fallopian tube.
The fallopian tube, also known as uterine tube or oviduct, carries the egg from ovary to the uterus.
The fallopian tube has finger-like projections or branches called fimbriae which reach out into the pelvic cavity and pick up an egg that has been released from the ovary.
The egg is tenderly brought into the fallopian tube where it begins to travel to the uterus.
The fallopian tube also serves as the location where fertilization of the egg by a sperm cell occurs.

Answer: B
Explanation:
The observed differences between the groups most likely resulted from differences in the ability of the seedlings to produce amino acids.
Differences observed in the plant groups would most likely be due to their differing abilities to produce glucose, a monomer that forms cellulose and other sugars vital for plant functions. Other options such as amino acids, cellulose and DNA also play crucial roles in the plant's life processes.
The observed differences between the groups most likely resulted from differences in the ability of the seedlings to produce glucose. Glucose is a monosaccharide, or a simple sugar, that serves as the primary fuel for plants. Glucose monomers form structures like cellulose, which primarily make up a plant's cell wall, providing it with structural support. Glucose is also involved in the formation of other types of sugars such as sucrose and lactose when combined with fructose and galactose, respectively.
However, it's important to note that all the options given - glucose, amino acids, cellulose, and DNA - are monomers or polymers that play vital roles in the life functions of a plant. Amino acids are the building blocks of proteins, cellulose is a structural polysaccharide composed of glucose units, and DNA holds the genetic information of the plant.
