Answer: Oval.
Explanation:
The nucleus of a cell is a membranous structure normally found in the center of eukaryotic cells and is where most of the cellular genetic material is found, organized in DNA molecules (deoxyribonucleic acid) associated with proteins such as histones, which make up the chromosomes.
The function of the nucleus is to maintain the integrity of the genes in the DNA and to regulate gene expression to control cellular activities. It then controls when DNA is transcribed into RNA (ribonucleic acid) and when it is exported to the cytoplasm to be translated into proteins.
The nucleus is composed of a nuclear envelope consisting of a double membrane that surrounds it, as well as pores that allow the passage of RNA for the regulation of gene expression.
The cells of the inner cheek are classified as non-keratinized stratified squamous epithelium. An epithelium is a tissue made up of joined cells that line the outer surface of the body and inner organs. Squamous cells are flat, scale-like, whereas stratified cells are arranged in multiple layers. Non-keratinized means that the cells constitute soft tissue found in the moist parts of our body, such as the mouth, stomach, among others. In a normal healthy cell, the nucleus is uniformly stained, oval in shape and smaller in relation to the cytoplasm.

hen
Answer:
The answer is B
Explanation:
Think of it this way; Respiration = Breathing and we are on the cellular level
Cellular respiration is the process of releasing energy from food. The correct option is A.
What is cellular respiration?Cellular respiration is the process of breaking down food molecules into simpler forms to produce energy in the presence of oxygen. The oxygen is added to the food to produce energy and release carbon dioxide and waste material out of the body.
Oxygen is taken from the environment, and they are attached to the hemoglobin molecule of the blood and taken into the body, then this oxygen is used in the metabolic function of the body.
Breathing is the process of getting air into the lung and out of the lungs. It is not a part of cellular respiration.
Thus, the correct option is A. The release of energy from food.

Two closely related beetle species are in the same location. They exhibit reproductive isolation, and they are both diploid. Biologists are arguing about whether it is more likely that they evolved via sympatric or via allopatric speciation. What statement presents the best argument
Well this isn’t biology this is earth science but it doesn’t have the option.... 1. What geologic processes must have occurred for fossil ammonites (relatives to the nautilus that dominated oceans hundreds of years ago) to now be found in rocks at the highest mountains on Earth??
2. What would our planet look like if it contained no radioactive isotopes within it? What would it look like if radioactivity were producing twice as much heat within Earth’s interior?
The answers are that the geological process responsible for fossils being found on high mountains today is called Orogeny Tectonics. With no radioactive isotopes, the Earth's geography would be vastly different and void of life. If radioactivity produced twice as much heat the earth would become unstable.
The discovery of fossil ammonites within rocks at the highest mountains on Earth is due to orogenic plate tectonics. Plate tectonics is the name we use to describe a process in which pieces of the earth's crust move and often slam into each other, causing one of these to pile onto the other.
This can lead to the formation of mountains and mountain ranges. This process helps to explain why fossils of ammonites known to dwell in the ocean can be found in mountains.
Radioactive isotopes, or better yet, the decaying of radioactive isotopes, are responsible for generating most of the Earth's internal heat. The internal heat of the earth is the driving force of plate tectonics and without it, much of the geological activities responsible for the earth's current geography would not have happened.
Mountain ranges would not have formedPlate tectonics would not have caused the formation of the continents we know todayThe earth would lack a magnetic field to defend against ionizing radiation from the sunLife would likely not have evolved.Radioactive isotopes were vital in allowing for the conditions of the earth at the time that life evolved, and the heat they produce allows the earth to have a molten core and thus generate a magnetic field for protection.
Now, if the heat produced by radioactive isotopes were to double, the Earth's internal temperature would nearly double. Since this heat is the driving force for plate tectonics, we can expect a sharp increase in the number of earthquakes and volcanic eruptions. These can, in turn, cause tsunamis and changes to the earth's global temperature. Mountains would form continuously and continents may break apart. This instability would make life on earth's surface improbable.
Therefore, the geological process responsible for fossils being found on high mountains today is called Orogeny Tectonics. Without radioactive isotopes, the Earth's geography would be vastly different and void of life. Radioactivity producing twice as much heat would make the earth very unstable.

Which capacity makes living beings to adjust in hard environment
The biological referred to as Adaptation makes living beings to adjust in exhausting atmosphere.
Adaptation, in biology, is that the method by that species measure suitable their several atmosphere, thanks to Natural Selection’s method ensuing into patrimonial variation over many generations.
What is Adaptation?According to Evolution, Adaptation method is that the process underneath that organisms suits the present atmosphere in conjunction with the modifications thanks to change in atmosphere.
Adaptation is connected with the idea of evolution that was propounded by Darwin and Wallace.
According to Wallace, the evolution of organisms was supported 2 factors: Adaptation and dynamic atmosphere.
To develop the idea of evolution by survival, Wallace and Darwin targeted not solely on straightforward adaptation however additionally proceeded more to clarify however organisms adapt and evolve.
Biologically Adaptation will be in 3 forms:
- Psychological kind
- generative kind
- sequence Frequency
Psychological form- associate degree animal or plant adapt by adjusting consistent with its immediate atmosphere.
Example- modification in temperature or metabolism with a rise in altitude
Reproductive form- method of adaptation thanks to genetic variations among people that is customized i.e. having larger success in—a specific environmental context.
Gene frequency- the method of adaptation happens through associate degree ultimate modification within the sequence frequency relative to blessings bestowed by a selected characteristic, like the coloration of wings within the moths.
Organisms will adapt to associate degree atmosphere in several ways in which. they will adapt biologically, which means they alter body functions
Example- individuals living at high altitudes have evolved changes in their body chemistry and may survive at high altitudes for a brief time as a result of their bodies raise their levels of hemoprotein.
They can additionally exhibit activity adaptation.
Example of activity adaptation is however emperor penguins in Antarctica foregather to share their heat within the middle of winter.
What is theory of Natural Selection?The theory of survival was given by Darwin in 1859.
Natural selection is that the method through that populations of living organisms adapt and alter.
Individuals in an exceedingly population square measure naturally variable, which means that they're all completely different in some ways in which.
This variation means some people have traits higher suited to the atmosphere than others. people with adaptive traits—traits that provide them some advantage—are a lot of seemingly to survive and reproduce.
These people then pass the adaptive traits on to their offspring. Over time, these advantageous traits become a lot of common within the population.
Through this method of survival, favorable traits square measure transmitted through generations.
Natural selection will cause phylogeny, wherever one species offers rise to a replacement and clearly completely different species. it's one among the processes that drives evolution and helps to clarify the range of life on Earth.
