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:

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

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.

Answers

Answer:

first box- A result of industrial manufacturing

second box- Methane

Explanation:

Im not for sure but this is what i believe it is if possible ill update

The pie chart indicates that deforestation in the Amazon rainforest is mostly driven by food production. The loss of large carbon-storing trees combined with the presence of methane-producing cattle is likely to intensify greenhouse gases in the Amazon.

What is deforestation in the Amazon rainforest?

Deforestation in the Amazon rainforest has significant environmental consequences. Trees store large amounts of carbon dioxide, and their removal contributes to increased greenhouse gas emissions, which are a major cause of climate change. Additionally, the cattle that are raised on cleared land produce methane, which is another potent greenhouse gas. As more trees are cleared to make way for agriculture and cattle farming, the carbon storage capacity of the forest is reduced, and more methane is released into the atmosphere.

Hence, the pie chart indicates that deforestation in the Amazon rainforest is mostly driven by food production. The loss of large carbon-storing trees combined with the presence of methane-producing cattle is likely to intensify greenhouse gases in the Amazon.

What are wetlands?

Wetlands are defined as areas where water either completely covers the soil or is present either at or near the surface of the soil throughout the entire year or for varying amounts of time at different times throughout the year, including during the growing season.

Our water is cleaned by wetlands because they filter out sediments, other pollutants, and even chemical contaminants. Additionally, wetland areas act as a filter for and a processing facility for excess nutrients that may run off from agricultural and development sites. Historically, people have referred to wetlands as "the kidneys of our watershed."

What is the elevation of point B

Answers

Answer: c. Point B has an elevation less than 2750 feet.

Explanation:

The lines drawn on the map are known as contour lines and they are used to measure elevation. Point B is on a river and rivers are only able to flow at a lower elevation than the area around them.

Point B is therefore lower than the area around it and as the closest contour line to it puts the area at an elevation of 2,750 feet, that must mean that Point B is lower than 2,750 feet.

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.

Transfer RNA has __________ bases attached to one end of the molecule and an amino acid to the other.

Answers

Answer:

Nitrogenous

Explanation:

Transfer RNA, also known as tRNA, is one of the three types of RNA. It is involved in the translation process. The shape of the tRNA allows it to be a very important component of the translation process.

The morphological structure of the tRNA is in such a way that a sequence of nitrogenous bases called ANTICODON attach to one of its ends while an amino acid is attached to the other end. This way the tRNA molecule is able to read the mRNA codon using its anticodons and carry the corresponding amino acids.

N.B; the anticodons are composed of three nitrogenous bases just like codons. Codons are complementary to anticodons.

The role played by the systems of the body in ensuring survival of farm animals in hot and dry climates

Answers

Answer:

Answer to the following question is as follows;

Explanation:

Domesticated animals have a natural instinct to seek out cover and seek refuge from the scorching heat. Their bodies, on the other hand, have inherent defensive systems to help them cope with heat and dryness. One of these is their covering or fur, which gives sun protection.

Animals living in hot, dry climates consume a lot of water, which is subsequently stored in their tissues to keep them from becoming dehydrated. Sweating is accomplished by certain animals by keeping their mouths open.

What are animals?

More than any other species, humans are capable of learning new things. Indeed, the majority, but not fully, of what distinguishes us from other animals is anchored in language.

In addition, because we have a backbone, humans are considered to be members of the chordate animal phylum.

The zygote is split into the blastula after fertilization, three germ layers develop in the blastula, which in some species is a hollow ball of cells, during a process known as gastrulation.

Therefore, humans are classified as members of the primate order within the animal group and having the blastula stage, hence option a is correct.
