Answer:Its the Vacuole

Explanation:

Answer:

There would be no seasons anywhere on Earth

Explanation:

If the Earth's axis was not tilting and it was at a 90 degrees angle relative to its orbit, then the seasons on Earth would disappear. The climate on the planet would be defined by the latitude. The equator and the areas close to it would always have summer, as they will receive direct sunlight throughout all of the year. The mid-latitudes will always have temperate climate, reminding of spring and autumn, as the sunlight will not be very direct, but it will also not be very dispersed, jut enough to create a constantly pleasant climate. The higher latitudes will always have winter, as the sunlight will come at a very low angle throughout all of the year, thus it will be very dispersed, not enough to ever warm this parts enough, so they will constantly be under ice.

Answer:

The entire planet would experience the same season at any given time.

Explanation:

Due to the tilt, some parts of the earth will be tilted towards the earth at a particular point in the orbit while others will be tilted away from the sun. This means the amount of sunlight reaching these points is differential. This also changes dynamically, more pronounced in the poles, as the earth revolves around the sun. Without the tilt, this phenomenon would not be therefore and there would be no changes as the earth revolves around the sun.

Tropical rain forest

Explanation: It supports a wide variety of species than any other biome. It is because it provides continuous water supply, constant warmth and a variety of food for the animals. Small animals like rodents, lizards, birds, snakes, frogs are common in this forest. Tall tress are used as shelter and also as source of food.

The tropical rainforest is the habitat known for a wide range of animals including birds, monkeys, snakes, and insects. This biodiversity-rich environment supports numerous species. The canopy is particularly important for bird species.

The habitat that is known for many species of birds, monkeys, snakes, lizards, frogs, and insects is the tropical rainforest. Tropical rainforests are incredibly biodiverse. They are home to a wide range of animals including numerous insect species, small mammals like bushpigs and bushbucks, and larger mammals such as monkeys and leopards. The canopy of the rainforest provides a perfect habitat for birds such as pigeons, eagles, and the Knysna Loeries.

Answer: Codons

Explanation:

The mRNA bases are grouped into sets of three, called codons. UAG is amber, UGA is opal (sometimes also called umber), and UAA is ochre. Stop codons are also called "termination" or "nonsense" codons.

Three bases found on mRNA, referred to as a codon, correspond to a particular amino acid, encoding the genetic information that is translated into a protein sequence.

Three bases found on mRNA are indeed referred to as a codon. The cellular process of transcription generates a strand of messenger RNA (mRNA), a copy of one or more genes within the DNA. This copy is composed of sequences, A, C, G, and U (uracil). Each triplet of bases, or codon, on the mRNA corresponds to a particular amino acid. In other words, the genetic code is a series of codons, and this code is translated into a protein sequence through the process of translation.

Answer:

The building blocks of proteins are amino acids. - The sequences of nucleotides/bases in DNA provide a genetic code for the sequence of amino acid connections, which form protein molecules.

Explanation:

Final answer:

Protein synthesis in animal cells is a critical energy-consuming process where ribosomes translate mRNA messages into polypeptide chains that fold into functional proteins. These proteins contribute immensely to cellular structure and function. The process is highly regulated and involves the mRNA template, ribosomes, tRNAs, and enzymatic factors.

Explanation:

Protein synthesis is a crucial process in animal cells that consumes more energy than any other metabolic activity. Proteins are essential for the structure, function, and regulation of the body's tissues and organs, and therefore constitute a significant portion of cellular mass, second only to water. The translation process involves decoding an mRNA message into a polypeptide chain, which eventually folds into a functional protein. This assembly is facilitated by ribosomes, which catalyze the formation of peptide bonds between amino acids, resulting in polypeptide chains that can range in size from around 50 to over 1,000 amino acids. These polypeptides undergo post-translational modifications before becoming fully functional proteins capable of performing a plethora of cellular functions.

The machinery involved in protein synthesis includes not just the mRNA template but also ribosomes, transfer RNA (tRNA), and various enzymatic factors. Each amino acid added to the growing polypeptide chain is selected by tRNA molecules that match the corresponding codon on the mRNA. This ensures that the sequence of the resulting protein is exactly as encoded by the gene. The process is highly regulated at the transcriptional and translational levels, ensuring that proteins are synthesized as needed by the cell.

C. Experimental data that support the conclusion

A good conclusion is defined when experimental data support the conclusion of any hypothesis because it does not cause any change in the hypothesis, hence option c is correct.

A conclusion is formed using the information gathered during an investigation and its repeats. The hypothesis may well be supported by the data or not.

After reading the article, the reader is supposed to understand from the conclusion why your research should be important to them. The final paragraph of a research paper, essay, or article that summarizes the whole work is the conclusion.

The conclusion paragraph should repeat your thesis, identify the important points you made in support of it throughout the paper, and provide your evaluation of the main concept.

Therefore experimental data support the hypothesis and lead to a good conclusion, hence option c is correct.

Answer:

an entire desert including abiotic factors

Explanation:

An ecosystem includes all living (biotic) and nonliving (abiotic) factors in an area that interact, therefore an entire desert including abiotic factors can be considered an ecosystem. The living community within a desert, the population of fish in a small lake, and a rotting log are all examples of an ecosystem due to their combined biotic and abiotic components.

Given the options presented in the question, an entire desert including abiotic factors can be considered an ecosystem. This is because the term ecosystem applies to a natural unit consisting of all the living organisms in an area functioning together with the nonliving physical factors of the environment. A community of organisms within a desert or a population of fish in a small lake both represent biotic communities, while the wood of a rotting log can also be classified as an ecosystem due to the interacting species and abiotic factors present.

scientists MUST test the hypothesis several times and if they keep getting the same results, it is now considered a theory.

Answer

Nasal cavity

Larynx

Pharynx

Trachea

Bronchi

Answer:

Nasal cavity, pharynx, larynx, trachea and bronchi.

Explanation:

Respiration may be defined as the process of the exchange of gases between the external environment, lungs and tissues. Oxygen is inhaled in and carbon dioxide is exhaled out from the body.

The first passage way of oxygen is the nasal cavity. From the nasal cavity, the air is passed to the pharynx. Pharynx is also known as the throat of the body. From the pharynx,  the air is passed to the layrnx. Larynx is the voice box. The air is then passed to the trachea or the wind pipe. From the trachea, the air is passed into the lungs that contains the small branches called bronchi.  From brochi to the alveoli and finally into the body tissues.

Thus, the answer is nasal cavity, pharynx, larynx, trachea and bronchi.

Answer:

It is an extrusive igneous rock

Explanation:

Based on the physical appearance, the geologist can make an accurate conclusion about the rock's formation and in which type of rocks does it belong. The fine-grains made up of small crystals give away clues about the formation of the rock. Fine grains with small structures occur when the lava reaches the surface and cools off very quickly, thus not giving the crystals enough time to grow, so they are very small. The geologist can classify this rock on base of this information as an igneous rock, as it has been formed from lava, and as an extrusive igneous rock, as the fine grains and small crystals only occur when the lava cools of quickly on the surface.

Answer:

A. share one common ancestor that isn't also shared by organisms in other groups.

Explanation:

A monophyletic group includes all the descendants of an ancestral species. On the other hand, a paraphyletic group includes some descendants of a common ancestor. Protists are not monophyletic as they share a common ancestor with other groups. Hence, protists are said to be paraphyletic. Mammals are monophyletic as all the mammals share a common ancestor which is not shared by organisms of any other groups.

Answer:

Density independent.  

Explanation:

Density independent factors refer to the limiting factors that affect the population is the same way regardless of the size of the population. It could be natural disasters, unusual weather and human activities such as clear cutting forests.

Answer:

Density independent

Explanation:

The limiting factor shown in the question above is independent of deity.

The term density-independent limiting factor is used in ecology, along with the deity-dependent factor to describe growth-limiting factors in a population. When a factor causes changes in the birth and death rates of a population it means that it is a density dependent factor, since it interferes with the population density.

However, when population mortality and birth rates are modified without changing the size of the population, the density of that population is not modified and this is an density independent factor.

Phylogenetic trees show that dolphins do not share the most derived characteristics with horses. Instead, they have a common ancestry with even-toed ungulates. The similar body shapes between dolphins and fish are an example of analogous traits due to convergent evolution.

Explanation:

​In biology, phylogenetic trees are used to show the evolutionary relationships between different species. These relationships are determined through various evolutionary characteristics which can either be shared or derived. Regarding the relationship among different animals, let's address the questions raised by examining their evolutionary traits.

When considering the evolution of cetaceans, which includes dolphins, we observe that they have derived from even-toed ungulates and share a common ancestry with several other mammals including the hippopotamus, cow, sheep, camel, and pig. This common ancestry indicates that a horse, which is also an ungulate, is not the closest relative to a dolphin within this context. An armadillo would not fall on the same branch of the phylogenetic tree close to horses or cetaceans.

Comparing DNA sequences among animals, a whale would share more sequences with a horse than with a shark because whales and horses are both mammals; whereas, sharks are fish with a very different evolutionary history. Lastly, the similar body shape observed between dolphins and fish is an example of an analogous trait, since dolphins are mammals and fish are not, their similar body shapes have evolved independently due to convergent evolution within similar environments.

B there is 7 electrons

An atom of nitrogen has (B) seven electrons.

In an atom in neutral state, number of electrons are equal to the number of protons. Since nitrogen has an atomic number of 7, which indicates the number of protons in its nucleus, it also has seven electrons to balance the positive charge of the protons and maintain an overall neutral charge.

Electrons are subatomic particles carrying a negative electrical charge. It is one of the fundamental particles that make up atoms, along with the protons as well as the neutrons. Electrons are a part of the family of elementary particles known as leptons. The movement of electrons within materials is responsible for electrical current flow and the generation of electromagnetic fields.
