Which of these statements about common names are true? Check all that apply. Common names are physically accurate descriptions of organisms. Multiple organisms can be called by the same common name. Multiple common names can be applied to one organism. Common names are uniform across the globe. Common names do not always translate accurately.
Answer:
Explanation:
The common name in biology can be defined as the name of a taxon or organism that is based upon the common language. The common name may vary depending upon the local language and country. It is the frequently used name.
Among the options given, following are correct:
1. Multiple organisms can be called by the same common name.: For example, various species of wolves can be commonly called as wolf.
2. Multiple common names can be applied to one organism.: For example, common name of rice can be paddy, sake and others.
3. Common names do not always translate accurately: Due to diversity of languages in the world the common names do not always translate accurately.
Common names for organisms can be ambiguous and are not used universally. Instead, the binomial naming system provides a unique and universally recognized name for every organism, like Homo sapiens for humans. This avoids confusion and facilitates global scientific communication.
Explanation:In relation to common names:
Common names are not physically accurate descriptions of organisms.Multiple organisms can be called by the same common name.Multiple common names can be applied to one organism.Common names are not uniform across the globe.Common names do not always translate accurately.The binomial naming system, introduced by Carl Linnaeus, helps provide a unique and universally recognized name to every organism, which includes the genus and species name, such as Homosapiens for humans. This system avoids the confusion that can arise from the use of common names, which can be variable and not specific to one organism. Common names can vary across different cultures and languages, which highlights the importance of the scientific naming system in global scientific communication.

What conclusions about atoms can you draw from the modern atomic model shown below? Choose all that apply.
Answer:
Hi,
The correct answers should be:
Electrons are smaller than protons
The majority of an atom’s mass is in the nucleus
Protons and neutrons are about the same size.
The first option is not true since in the picture you can see three different kinds of particles, while the second one is false since different electrons can occupy different energy levels and the same electron can “jump” from one energy level to another one if stimulated.
Hope this helps! If my answer was not clear enough or you’d like further explanation, please let me know.

A pea plant with round seeds (RR) is crossbred with another pea plant with wrinkled seeds (rr). What is the probability of the offspring having wrinkled seeds? 0% 25% 50% 75%
Answer:
0%
Explanation:
The cross of a pea plant with round seeds (RR) with another pea plant with wrinkled seeds (rr) is shown as under :
P RR x rr
F1 Rr Rr Rr Rr
It is clear from the cross above, all the 4 probable progenies in filial 1 (F1) generation will be heterozygous with Rr genotype. Not even a single progeny will have homozygous recessive genotype which is responsible for producing wrinkled seeds. Also, even though the genotype of the progenies will be Rr not RR yet phenotypically they all will have round seeds i.e. they will show dominant trait. The reason behind it is that one of the alleles R which is responsible for dominant trait will mask the expression of recessive allele r. So, wrinkled phenotype which is a recessive trait will not be observed in any of the progenies.

How do scientists determine when an era ends and an era begins
Scientists determine the beginnings and endings of eras based on significant shifts in Earth's geology and life forms, often identified through major geological events and changes in the fossil record. Each era in geologic time represents long time spans categorized by distinct characteristics. Scientists use fossil records, geological markers, and research to define these eras and their transitions.
Explanation:Scientists, specifically geologists and paleontologists, determine when an era ends and a new one begins based on significant shifts and changes in the Earth's geology and its life forms. This is often identified through the fossil record and major geological events. For example, the end of the Cretaceous era is marked by a significant mass extinction event, including the disappearance of dinosaurs.
An era in geologic time is a long time span, typically billions of years, categorized by distinct characteristics, such as the presence or absence of certain types of fossils. Each era is then divided into periods, epochs, and ages which relate to marked changes in the fossil record or geologic events.
In essence, scientists use a combination of fossil records, geological markers, and ongoing research to define eras and their transitions. This makes the understanding of Earth's history more organized and comprehendible.

all cells (prokaryotic and eukaryotic) have few common features. which cell feature is found in both prokaryotic and eukaryotic cell? A chloraplast B ribosome C nucleus D sodium
The ribosome is a common cell feature between prokaryotes and eukaryotes. So the correct option is B.
What are ribosomes?The process of making proteins in a cell takes place at an intercellular structure called a ribosome, which is formed of both RNA and protein. The messenger RNA (mRNA) sequence is read by the ribosome, which then converts the genetic code into a specific string of amino acids that develop into extended chains and fold to create proteins.
The biological machinery that produces proteins is known as a ribosome. Each cell has several ribosomes, which are each composed of two subunits. These two subunits form a tight seal around the messenger RNA molecule before moving down its length and reading each three-letter codon.
The transfer RNA, whose base sequence matches that of the messenger RNA, docks to the ribosome. A specific amino acid can be added to the end of the expanding protein chain by pairing each three-letter messenger RNA codon with the corresponding anticodon on a particular transfer RNA. Once the protein is finished, the ribosome fragments.
Therefore the correct option is B.

Explain why isostatic rebound slow over time
Answer:
Explanation:
This is due to isostatic equilibrium.
Isostatic rebound occurs when load is added or removed on the lithosphere and the surface either sinks or rises under the weight of the asthenosphere.
At first, when load which can be in form of glacier is added to the lithosphere, this block of the earth would sink rapidly at first due to the added weight. With time, as the adjustment continues, an equilibrium is now reached between the lithosphere and the asthenosphere. At this point, the asthenosphere would have gathered enough strength to carry the overlying weight.
Isostatic rebound is slow due to the viscous nature of the Earth's mantle needing time to adjust after glacial melting. It's evident in regions previously covered by ice, like parts of Canada, where the Laurentide Ice Sheet's melting allows the crust to rise at about 2 cm/year. The gradual rebound continues as the mantle material redistributes over thousands of years.
Isostatic rebound is the process of the Earth's crust rising as the result of the removal of mass, such as the melting of glacial ice. This phenomenon is slow because the Earth's mantle behaves like a viscous fluid over long periods, taking time to adjust and redistribute material after the weight from the ice sheets is removed. Since the last glacial period, regions like Canada and Scandinavia, previously covered by massive ice sheets, have been experiencing this rebound.
The crust sinks under the weight of thick ice accumulations during periods of glaciation. After the ice melts, the mantle underneath, which was displaced to the sides, allows the crust to rise slowly back to its original position. For example, in areas west of Hudson Bay in Canada, where the Laurentide Ice Sheet was the thickest, the crust is rebounding at nearly 2 cm/year, showing some of the highest rates of uplift in the world.
The slow nature of isostatic rebound can be further illustrated through the rebound rates worldwide. In areas like British Columbia, the uplift is weaker compared to regions where the ice was thicker. Such gentle uplifts, particularly in coastal and offshore areas, indicate ongoing adjustments in displaced subcrustal material, a process taking thousands of years.
Outline THREE uses that cells make of energy released by ATP.
Final answer:
Cells make use of the energy released by ATP in active transport, mechanical work, and biosynthesis.
Explanation:
Cells make use of the energy released by ATP in multiple ways:
Active transport: ATP powers the movement of molecules across cell membranes, against their concentration gradients. This includes the transport of ions, such as sodium and potassium, across nerve cell membranes for nerve impulse transmission.
Mechanical work: ATP provides the energy for muscle contraction and movement. When myosin heads bind to actin filaments, ATP is hydrolyzed to provide the necessary energy for muscle contraction.
Biosynthesis: ATP is used in various biosynthetic pathways to provide energy for the synthesis of complex molecules, such as proteins, nucleic acids, and carbohydrates. For example, ATP is required for adding new nucleotides to a growing DNA strand during DNA replication.

Plants, algae and phytoplankton are the main components of the _________ carbon cycle.
Is it fast or slow
Answer: Fast
Explanation: Fast carbon cycle include the process which can circulate the carbon in the ecosystem in comparatively less time. For example, carbon dioxide is taken up by plants and converted into food, which is consumed by animals. Animals then release carbon dioxide which is again consumed by plants. So this is a repeatedly undergoing cycle. The main process involved behind this is photosynthesis. All the three- plants, algae and phytoplanktons perform photosynthesis, so they are the part of fast carbon cycle.

What do you mean by species?Most evolutionary biologists distinguish one species from another based on reproductivity: members of different species either won't or can't mate with one another, or, if they do, the resulting offspring are often sterile, unviable.
Most people recognize biodiversity by species—a group of individual living organisms that can interbreed. Examples of species include blue whales, white-tailed deer, white pine trees, sunflowers, and microscopic bacteria that can't even be seen by the eye.
Scientists have estimated that there are around 8.7 million species of plants and animals in existence. However, only around 1.2 million species have been identified and described so far, most of which are insects.

suppose Mendel crossed two pea plants and got both tall and short offspring. what could have been the genotypes of the parent plants? what phenotype could not have been present? Be sure to explain why.
If Mendel crossed two pea plants and obtained both tall and short offspring, then it is possible that the parent plants were both heterozygous for the gene that controls the height.
What could have been the genotypes of the parent plants?When these alleles combine in the offspring, there is a 25% chance of getting a homozygous dominant (TT) plant (which would be tall), a 50% chance of getting a heterozygous (Tt) plant (which would also be tall), and a 25% chance of getting a homozygous recessive (tt) plant.
Therefore, it is possible that the parent plants were both heterozygous (Tt) for the height gene, which would result in both tall and short offspring.
The phenotype that could not have been present would be a plant with an intermediate height between tall and short, as this is not how the height gene is inherited in pea plants.

The parent pea plants Mendel crossed to produce both tall and short offspring were likely heterozygous tall (Tt x Tt). Medium-sized plants could not have been present because pea plant height does not exhibit incomplete dominance. A Punnett square for this cross would show a genotypic ratio of 1:2:1 and a phenotypic ratio of 3 tall: 1 short.
Explanation:If Mendel crossed two pea plants and got both tall and short offspring, the genotypes of the parent plants could have both been heterozygous for the tall trait (Tt). A heterozygous organism has one dominant and one recessive allele for a trait, so when crossed with another heterozygous organism, they can produce offspring with a mix of phenotypes. Tallness is a dominant trait in pea plants, while shortness is recessive.
The phenotype that could not have been present in the offspring of two heterozygous tall plants is medium-sized plants. This is because height in pea plants does not exhibit incomplete dominance, where a blend of traits might be present, but follows Mendel's principle of dominance. Hence, the tall trait (T) being dominant would mask the expression of the short trait (t) in a heterozygous organism (Tt), resulting only in tall plants. A short offspring could only appear if it were homozygous recessive (tt), receiving a recessive allele (t) from both parents.
Using a Punnett square to predict the offspring of a cross between two heterozygous tall pea plants (Tt x Tt), the genotypic ratio would be 1 TT : 2 Tt : 1 tt, which corresponds to a phenotypic ratio of 3 tall : 1 short. This is because the chance of an offspring receiving two dominant alleles (TT), one of each (Tt), or two recessive alleles (tt) varies, with TT and Tt resulting in the tall phenotype and only tt resulting in the short phenotype.
When the heterozygous genotypes results in a phenotype where both alleles are fully and separately expressed
Codominance is a condition where both alleles are fully and separately expressed in a heterozygous genotype. An example is the blood types in humans, where IA and IB alleles are codominant, resulting in the AB blood type.
Explanation:When both alleles are fully and separately expressed in a heterozygous genotype, this is called codominance. In codominance, both alleles affect the phenotype in separate and distinguishable ways. For example, in the case of blood type, a person can have the genotype IAIB, which represents type AB blood. Here, both IA and IB alleles are codominant, resulting in a phenotype (blood type) where both alleles are expressed. This is different from incomplete dominance, where the phenotype of the heterozygous genotype is an intermediate expression of two alleles.
