a scientist is observing a eukaryotic cell and a prokaryotic cell. which structure could she only observe in the eukaryotic cell?

A.) cytoplasm

B.) DNA

C.) ribsomes

D.) Nucleus​

Answers

Answer 1

Answer:

The answer is D. Nucleus are only found in Eukaryotes.

Answer 2
Answer: D.) Nucleus

Explanation: In the question, we are told to find a structure that is found ONLY in eukaryotic cells. Because of this, we have to eliminate any option that is found only in prokaryotic cells, or any that is found in both prokaryotic and eukaryotic cells. In options A-C, we are given structures found in both types of cells. The cytoplasm, DNA, and ribosomes differ in each type of cell; however, nevertheless, they do not only appear in eukaryotic cells. This makes nucleus the only valid option, as it is only found in eukaryotic cells.

Why do biologists classify

Answers

Answer:

Biologists classify organisms because:

Classification allows us to understand diversity better.  It helps in the identification of living organisms as well as in understanding the diversity of living organisms. Classification helps us to learn about different kinds of plants and animals, their features, similarities and differences. It enables us to understand how complex organisms develop from simpler organisms.  They are grouped under different categories to understand and study the features, similarities and differences between different living organisms. It is essential to understand the inter-relationships among the different groups of organisms. Classification forms a base for the development of other biological sciences.

Why the water is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance?

Answers

Why is water colorless?

It is actually not. It is weakly blue which becomes apparent when a lot of it is gathered in one place. It is definitely not very strongly colored though. That is very common. Very few pure simple substances are strongly colored. Pure salt and sugar are transparent and colorless too. In bulk they look white because the tiny crystals scatter light, but snow does the same. A liquid forms one homogeneous mass.

In nature, of course, substances are rarely pure. Therefore not so many things look colorless. It only takes a little bit of a strongly colored impurity to color the whole thing. Just look at Himalaya salt or unrefined sugar or orange juice.

Why is water tasteless?

Because we don’t need to taste it. We get a good idea of the water content of food from the feel of it. Other liquids are usually oils, which feel very different. Besides it is not all that important exactly how much water is in one particular food item, if we need hydration then we drink stuff which is definitely mostly water.

The sense of taste not registering water frees up capacity to detect other things.

Why is water odorless?

Likewise because we don’t need to smell it. There is no real evolutionary advantage to be able to instantly tell the moisture content of the air. Better to use the sense of smell to detect poisons, food nearby, relatives or strangers etc. than to tell how the weather is today. We can tell how the weather is by other means.

Answer:

Water is inorganic, transparent, delicate, odourless, and almost colourless.

Explanation:

How colourless is the water?

In fact, it isn't. It's weakly blue, and when many of them are gathered together, it gets obvious. However, it's obviously not very colourful. This is a pretty common occurrence. Very few simple materials are coloured intensely. Pure salt and sugar are also colourless and clear. They look white in mass because the little crystals disperse light, but the snow does the same. A fluid forms a uniform bulk.

Substances are seldom pure in nature, of course. Not so much looks colourless, therefore. It takes just a few colourful uncleanness to colour the whole thing. Look for Himalayan salt or sugar or orange juice unprocessed.

Why is water odourless?

We don't have to taste it because of this. From that feeling, we obtain a decent estimate of the water content of food. The oils, which feel much different, usually are other liquids. Moreover, the exact amount of water in a certain food item is not all so important, if we need moisture we will certainly drink things that are primarily water.

The sensation of taste without water releases the ability to discern other things.

Why does water smell?

We don't have to smell it, too. There is no genuine advantage of being able to identify the humidity of the air instantaneously. It's better to use the sense of smell to detect poisons, nutrients, relatives or strangers, etc. IN various ways, we can tell how the weather is.

The Ames test involves mutants of Salmonella that __________ the ability to make histidine in the __________ of a suspected mutagenic chemical.

Answers

Answer:

gain; presence

Explanation:

The Ames test is a lab methodology used to determine whether a particular chemical substance can trigger mutations in an organism, which can be used to indicate whether exposure to the target chemical compound is associated with a greater risk of developing cancer. The Ames test can use a strain of Salmonella typhimurium carrying mutations in a key gene that encodes a protein involved in histidine biosynthesis. In consequence, this S. typhimurium strain is considered to be a 'histidine auxotroph' which is unable to synthesize histidine residues. After exposure to the target chemical compound, bacteria are then cultured in a medium lacking histidine. Subsequently, bacteria that regain the ability to synthesize histidine proliferate to form colonies. Finally, the number of these colonies is then compared with the number of mutants in absence of the potential mutagen, enabling thus the determination of the mutagenic potential of the target chemical compound.

What can you tell about an igneous rock that has a coarse-texture?
A. It is a carbonate.
B. It probably formed in a volcanic eruption.
C. It is most likely formed underground.
D. It is extrusive.

Answers

Answer: It is most likely formed underground

An igneous rock that has a coarse texture is one that formed from slowly cooling magma deep within the Earth's crust, or from slowly cooling lava on the surface. The slow cooling allows large mineral crystals to grow, giving the rock a coarse, grainy texture.

What can the size and shape determine ?

The size and shape of the mineral crystals within the rock can provide information about the rock's cooling history and the conditions under which it formed. Coarse-grained igneous rocks such as granite, gabbro, and diorite typically have crystals that are visible to the open eye, with sizes ranging from a few millimeters to several centimeters in diameter.

The composition of the rock can also be determined based on the types of minerals present in the coarse-grained texture. For example, if the rock contains primarily feldspar and quartz, it is likely a granite. If it contains mainly plagioclase feldspar and pyroxene, it is likely a gabbro.

Overall, the coarse texture of an igneous rock indicates that it cooled slowly over a long period, allowing mineral crystals to grow and form a visible grain structure. The size and composition of the crystals can provide clues about the rock's history and origin.

Answers

Answer:

pressure gradient

Explanation:

The correct answer would be pressure gradient.

A pressure gradient is created when there is a difference in the amount of pressure between two points or locations that are adjacent to one another.

In this case, the two locations that are adjacent to one another are the inside and outside of the lung. When one breathes in, the pressure inside the lung is more than that of the outside and the lung expands as a result. When we breathe out, the pressure outside is more than that of the inside and the lung collapses.

Answers

flowers that bloom in different months

Flowers that bloom in different months is an example of temporal isolaton.

What is temporal isolation?

Temporal isolation is a type of reproductive isolation that occurs when two or more species reproduce at different times, thereby preventing mating between them. This can happen in a variety of ways, such as when one species is active during the day and the other at night, or when they breed during different seasons.

Temporal isolation can lead to the evolution of new species because it prevents interbreeding between populations that would otherwise exchange genetic material. Over time, these isolated populations can accumulate genetic differences that make it increasingly difficult for them to interbreed, leading to the formation of distinct species that are reproductively isolated from one another.
