which of the following structures do all eukaryotic cells contain?
Answer:
A) A nucleus
Explanation:
Nucleus is the structure that all eukaryotic cells contain as represented by the diagram. Nucleus is present inside the cell and located in the center of the cell.
What is nucleus?Nucleus is defined as a membrane that is enclosed cell organelle inside a cell and it contain chromosome.The main function of nucleus is to regulate and controls the activities of the cell. It is also known as brain of the cell as it regulates and controls all the function of the cell.
The structure of nucleus is that it contains a structures such as nuclear envelope, nucleoplasm, or it is also known as nucleus sap or nuclear matrix, nucleolus and chromatin.
Nucleus stores the DNA of the cell and maintain its integrity, and provide it for the process of transcription, traslation and replication.
The nucleus contain nucleolus and the region is black and chromosomes have beeds like structure on them and they are known as genes that helps to pass a particular character from one generation to other generation.
Therefore, Nucleus is the structure that all eukaryotic cells contain as represented by the diagram. Nucleus is present inside the cell and located in the center of the cell.

In an experiment, 1000 rodents were released into a light brown sandy area where no rodents previously existed. The rodents' fur color was either brown, black, or tan. There was a known predator of the rodents in the same area. After several generations, what fur color frequency would a researcher expect to see?
Answer:
It is expected that rodents with brown color have more chances to increase their frequency in the population
Explanation:
The cryptic coloration (or camouflage), is an adaptation that organisms have developed to disguise their appearance, thereby blending in with the surrounding environment. The cryptic coloration is used by organisms as a strategy to hide their identity, movement, and location from their predators. In this case, it is expected that organisms with the same color of the surrounding environment would be the best to be selected by natural selection, i.e., these organisms would have more chances to survive and to reproduce.

What is parasitic mode of nutrition? Explain with examples.
Answer:
Explanation:
ANSWER 1) Parasitic nutrition is a mode of heterotrophic nutrition where a parasitic organism lives on the body surface or inside the body of another type of organism (a host)
Examples of parasitic mode of nutrition are mosquito, ticks, lice, bedbugs , tapeworm
because lives on the body surface or inside the body of other organism called host.
ANSWER 2 ) Organisms that live in or on other organisms and acquire food at the expense of its host are called parasites. Most parasites are harmful to the hosts’ health; sometimes, they even kill the host. Both animals and plants may serve as a host. Unlike commensalism, the parasite causes some harm to its host. A few examples of parasites are louse on a human head, Cuscuta plant and tapeworms.
Cymothoa exigua is an unusual parasite. It is also known as the tongue-eating louse and is aptly named so as it is found in the mouth of the marine fish Lithognathus. It essentially severs the fish’s tongue, cutting off the blood supply and causing the tongue to fall off. The louse then attaches itself to the remains of the tongue and essentially acts as the fish’s new tongue.

The average temperature of the surface of Earth has increased approximately 1°C in
the past century. Which reason best explains this increase in temperature?
Th average temperature of the earth has been increased as a result of
higher level of carbon dioxide and other greenhouse gases in the
atmosphere.
The carbon dioxide and other greenhouse gases has increased over the
past century as a result of the emission of these gases by automobiles,
industries etc.
These gases deplete the ozone layer which is responsible for the
absorption of sun rays .When this happens, the sun rays reaching the earth
will be increased thereby causing an increase in temperature.

How do cells maintain homeostasis in different environmental conditions?
[tex]\huge\pink{Answer}[/tex]
Homeostasis at the cellular level is critical to maintaining homeostasis in the whole organism. Animal cells have several ways to help them stay in equilibrium.
Cell Membrane and Phospholipid BilayerThe cell membrane functions as a boundary separating the internal cellular environment from the external environment. It is selectively permeable which means it lets some materials pass through but regulates the passage of other materials.
Ion Transport MechanismsThere are several ion transport mechanisms within the cell membrane that function to maintain proper levels of solutes inside and outside the cell. One of the most important is the sodium-potassium ATPase pump.Another critical pump is the calcium ATPase pump which moves calcium out of the cell or pumps it into the endoplasmic reticulum. This transfer of ions back and forth across the membrane creates a membrane potential that drives the ionic currents.
Cellular CommunicationThere are three basic kinds of intercellular communication used to maintain homeostasis. The first is when direct contact occurs between the membranes of two cells and they signal to each other. The second is when cells use short range chemical signals over short distances. The third is long ranged signals that are secreted into the bloodstream and can be carried anywhere in the body.

A student is studying Earth's layers. She is trying to determine how temperature and density change from one layer to another. Which relationship that exists between Earth's layers did the student most likely find?
A. The temperature of Earth's layers decreases with depth, while density increases with depth.
B. The temperature of Earth's layers increases with depth, while density decreases with depth.
C. The temperature and density of Earth's layers decrease with depth.
D. The temperature and density of Earth's layers increase with depth.
Answer:
The answer is D!
As one gets closer to the Earth's core, temperature, and pressure rise gradually. Thus, option D is correct.
What are the factor involving in the earth layer study?Gravity will tug on something more strongly the denser it is. The consequence is that less dense layers migrate away from the Earth's core, while the densest components are attracted closer to it.
Because it is the densest and is formed of solid iron and nickel, the inner core is located near the center of the Earth.
The surface, where the water is the warmest, has the lowest density. The pycnocline is a zone of rapidly rising density with depth that is present as depth increases.
The density has an inverse relationship with volume and a direct relationship with mass. As a result, the density rises as the volume shrinks.
Therefore, The temperature and density of Earth's layers increase with depth.
