How would seasons on Earth differ if Earth's axis was at a 90 degree angle relative to its orbit?
Seasons on Earth would not be affected.
The entire planet would experience the same season at any given time.
There would be no seasons anywhere on Earth.
It would always be summer at the equators and winter at the poles.
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.

Three bases found on mRNA are called a?
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.
Explanation: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.

which of these bones is part of the axial skeleton
Hello. This question is incomplete. The full question is:
"Which of these bones is part of the axial skeleton
A. Ulna B.fibula C.vertebra D.phalanges "
Answer:
C.vertebra
Explanation:
The axial skeleton is made up of bones that are close to the central axis of the body. In an adult this skeleton is formed by 80 bones that includes bones that form the cranium, the spine, the ribs and the sternum.
It is in the spine that we find the vertebrae. With this we can say that among the bones shown in the question above, the one that is part of the axial skeleton is the vertebra.
In the spine we find the following vertebrae:
Cervical vertebrae Thoracic Vertebrae Lumbar Vertebrae Sacral bone containing five fused vertebrae; The coccyx bone containing four to five vertebrae, also fused.The Axial Skeleton consists of the bones of the head, vertebral column, the rib cage and the sternum. Hence, a bone part of this section would have to be from one these areas.
Explanation:The Axial Skeleton is the part of the skeleton that consists of the bones of the head and trunk of a vertebrate. In humans, it consists of 80 bones and includes the skull, vertebral column, rib cage and the sternum. Therefore, if you're considering a bone to be a part of the axial skeleton, it would have to belong to either the head, vertebral column or the rib cage.

does a horse and dolphin have the most shared derived characteristics?
Answer:
no
Explanation:
because there Gene's are totally diffrent
Final answer:
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.
which of the following can be considered an ecosystem?
the community of organisms within a desert
an entire desert including abiotic factors
a population of fish in a small lake
the wood of a rotting log
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.

Is this individual male or female? How can you tell?
In biological terms, the sex of an individual is primarily determined by the X and Y chromosomes in mammals, with XX indicating a female and XY indicating a male. However, in some species, sex can change during one's lifetime. Gender identity can differ from biological sex, acknowledging the spectrum beyond male and female.
Explanation:The determination of whether an individual is male or female can largely be based on the X and Y chromosomes in mammals. Individuals homozygous for X (XX) are female and heterozygous individuals (XY) are male. The presence of a Y chromosome instigates the development of male traits and its absence results in female characteristics. This XY system is found in some insects and plants as well. However, it is important to remember that people often use the terms 'male' and 'female' to describe both our biological sex and our gender identity. For some, gender identity might be different from their biological sex or the sex they were assigned at birth. In these explanations, 'female' and 'male' refer strictly to biological sexes.
Furthermore, some species can change sex during their lifetime, alternating between male and female; this is known as protogyny (female first) or protandry (male first). Also, some creatures, such as certain types of snails, are hermaphrodites. When two individuals mate, they both can produce eggs, exhibiting characteristics of both sexes.

What is the synthesis of proteins in an animal cell
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.

Arrange the parts of the respiratory tract in a sequence that accurately represents the flow of air after a person inhales.
pharynx
trachea
bronchi
nasal cavity
larynx
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.
15. A geologist discovers a sample of fine-grained rock made up of very small crystals. Based on its physical appearance, what can the geologist conclude about the rock?
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:
It formed from rock that cooled quickly

Which could describe the motion of an object?
Answer:
Distance=10 meters and displacement=10 meters
Explanation:
Did the quiz
When an object is moving, it has a velocity, which includes both speed and direction.
The simplest motion to describe is one-dimensional motion, such as a train on a straight track. Knowing the object's position as a function of time is crucial for understanding its motion.
When an object is moving, it has a velocity. Velocity is the rate of change of the position of an object. It includes both the speed of the object and the direction in which it is moving. In contrast, speed describes only how fast an object is moving, not the direction. For instance, a car traveling north at 60 km/h has a different velocity than the same car traveling south at 60 km/h, even though the speed is the same in both cases. The simplest motion to describe is one-dimensional motion, like a train moving along a straight track. To accurately describe this motion, we need to know the object's position as a function of time, labeled as x(t). Understanding concepts like kinematics is essential for accurately analyzing motion in physics.

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.
