Answer:
They can be identified by the amount of protons, electrons, and neutrons.
Answer:
The physical properties are different ways to identify the element in the periodic table.
Explanation:
The substance which cannot be separated by any types of external forces are called element. In periodic table, these elements are arranged based upon the atomic number with element specific symbols. In order to identify the element, two methods can be used.
If the symbol or atomic number is given, the element can be identified by correlating it with the periodic table, on the other hand, if the element is given it can be identified by the physical properties such as color, texture, flame test, etc.
Which process is similar to binary fission
Explanation:
Mitosis is the process that is very similar to binary fission. Binary fission mainly occurs in prokaryotes like bacteria while mitosis occurs in prokaryotes as well as Eukaryotas like plant and animal cell.
Mitosis occurs in the place of injury and also maintains the shape of the body. Both binary fission and mitosis leads to the formation of two identical cells. However, the process by which binary fission and mitosis occurs are completely different.
A carbon atom can bond with other atoms in a variety of ways. Wich set of bonds would a typical carbon atom in a compound
Answer:
A carbon atom can form up to four covalent bonds as one carbon atom has four valence electrons (in outermost shell). It is a fact that the number of valence electrons in a atom determines the number of covalent bonds it will form. Thus, each electron in carbon atom is used to form four covalent bonds with various four atoms.
Explanation:
A bond between a carbon and hydrogen atom is a non-polar covalent bond. The non-polar covalent bond are the bonds between two atoms which share equal number of electron(s) with each other. Example: as in case of methane, where one carbon atom shares its 4 outer valence electrons with four hydrogens by sharing equal number of electron.
In contrast, polar covalant bond are the bonds between two atoms which share unequal number of electron(s) with each other. Thus these bonds are partially ionic.
What fats are called saturated?
A). fats that contain no double bonds in fatty acid chains
B). fats that have some double bonds in fatty acid chains
C). fats that have triple bonds in fatty acid chains
D). none of the above
Answer:
A
Explanation:
Fats are made up of several carbon chains – of different lengths- per molecule. An example is triglyceride with 3 fatty acids connected to glycerol. When several chains without double bonds are brought together – they attract each other tightly through the numerous hydrogen bonds they share between the chains. Presence of double bonds in the chains form kinks within the chains and disrupt the hydrogen bonds shared between chains. It is therefore common that solid fats are saturated fats because they bond so tightly they require higher temperatures to get to meting point as compared to unsaturated fats.
A cell makes and secretes a certain protein. Explain where it is made, how it is secreted from
the cell, and what kind of transport is used.
Answer:
The cell's proteins are first manufactured in the ribosomes. The polypeptide chains then enter the lumen of the Rough Endoplasmic Reticulum where they are properly folded with the help of chaperones and modified to achieve their desired shape which relates to their function. The proteins also undergo quality control in the RER, These proteins are then transported by vesicles, budding out of the trans side of the RER, and transported to the cis side of the Golgi apparatus. In the Golgi bodies, the proteins undergo further post-translational modification and packaging. Vesicles carrying the final proteins then bud off of the trans side of the Golgi apparatus and transport the protein to the cell membrane where they secreted them.
The protein is made in the ribosome organelle, secreted by transport vesicles using a type of transport called exocytosis.
Proteins are products of gene expression, which consists of transcription and translation of genetic material to produce them.The translation process, which occurs in the ribosomes, produce amino acids sequence that eventually become proteins. Ribosomes are site of protein synthesis in a cell. The proteins are secreted to target locations via the aid of structures called transport vesicles. Transport vesicles, carrying proteins, attach themselves to the cell membrane and release their protein content via the process of exocytosis. Therefore, protein is made in the ribosome organelle, secreted by transport vesicles using a type of transport called exocytosis.Learn more at: https://brainly.com/question/11660031?referrer=searchResults

Sickle-cell anemia is an example of codominance. What implications does this have for people with one or two copies of the sickle-cell gene?
Answer:
Sickle cell anemia is a genetical disorder that occurs when both the alleles from both the parents in the offspring is recessive. If only one gene is recessive, then the person will not have the disease.
It is a disease in which the shape of the red blood cell alters from biconcave disc shape to sickle shaped because of the mutation in hemoglobin gene. It is a case of incomplete dominance in which for the disease to occur, both the genes have to be recessive.

Which event occurs in the large intestine?
A.) Bile is released.
B.) Chyme is absorbed.
C.) Starch is digested.
D.) Water is recovered.
Answer:
D.) Water is recovered.
Explanation:
Large intestine is a part of alimentary canal. The food gets digested by the time it reaches here. So large intestine has no role in digestion. Its main function is to absorb water from the remaining undigested food matter so that solid stool can be produced and wastes be eliminated from the body. The absorbed water is returned to the body and reutilized.
Large intestine has a lining of mucosa which has tiny indentations called as crypts of Lieberkühn. They have many glands and goblets cells that are involved in absorption of fluids and secretion.

1)Why is the lion niche critical to maintain a healthy community?
2)Which sex is mainly responsible for this niche ?
Answer:
1) They maintain a healthy ecosystem by controlling the populations of other species.
2) Female lions hunt while males tend to take care of the cubs.
Explanation:
1) Lions have extremely important roles in the ecosystem. As a top predator, they control populations of herbivore species. If lions weren't present in the ecosystem there would be an overpopulation of fauna species.
According to research, if lions disappeared, other species, such as buffalos, would become the top predator. This would have major consequences as they tend to be the target of many parasites due to their sedentary behavior. Therefore, without lions there would be a higher rate of parasitic diseases.
2) Female lions are the ones who generally exhibit hunting behavior. They tend to be around 30% faster than males and blend better with the surroundings, allowing them to perform better stalking and hunting techniques. Although male lions do hunt occasionally, they are mainly dedicated to the protection of the offspring.

Patients forgetting to take their antibiotics are not the sole cause of antibiotic
resistance. Explain at least two other possible causes of the development of
antibiotic resistant bacteria.
Answer: Taking antibiotics to often and mutation in bacterial gene
Explanation:
The other two possible reasons that can cause the antibiotic resistant gene in the body is the taking antibiotics too often.
The antibiotics are taken too often that the body becomes resistant and the bacterial species are not killed by the antibiotics.
The second cause is that the bacteria might mutate and becomes resistant to the bacterial genome. In this case the antibiotics does not affects the bacterial species.

A population is a group of individuals of the same species that are capable of interbreeding and producing fertile offspring within a specific geographic area. Population ecology studies these groups, their interactions, and their environmental impacts.
Explanation:A population is a group of individuals in a single species that mate and interact with one another within a limited geographic area. In the field of population ecology, this is a critical concept, as ecologists study how populations of the same species interact, reproduce, and share the environment. A key aspect of a population is that its members can interbreed and produce viably, fertile offspring. This defines the concept of a species, wherein members of one species do not typically produce fertile offspring with members of another species.
For example, the specific name in the binomial nomenclature, like 'sapiens' in Homo sapiens, designates the species name. Consequently, all the Homo sapiens individuals around the world are considered part of the same species because they meet the criteria for interbreeding and fertile offspring production.
Populations are often defined in part by the natural or artificial boundaries of their habitat, such as rivers, mountains, or human-made structures, which can affect their size and interactions.
2. What is the effect of differential reproduction over time?
changes in a population's gene pool
the overproduction of beneficial traits
interbreeding of two or more populations
the disappearance of beneficial alleles
Answer:
A- Changes in a population's gene pool. That's your answer.
Answer:
The correct answer is- changes in a population's gene pool
Explanation:
Differential reproduction suggest that those organism who are well adapted to there environment and reproductive fit are more likely to survive till reproductive age and are more likely to produce their offsprings.
So only those genes will pass to the next generation which is more suited to the environment and the less adapted genes will disappear over time due to differential reproduction.
Therefore if some genes are lost over time by loss of less reproductive suitable individuals of a population then their gene pool also changes because the gene pool is the sum of all the genes found in a population.
Therefore the correct answer is-changes in a population's gene pool.

what step in the carbon cycle didn’t exist before the industrial revolution?
Final answer:
The step in the carbon cycle that didn't exist before the Industrial Revolution is the release of carbon dioxide from burning fossil fuels.
Explanation:
The step in the carbon cycle that didn't exist before the Industrial Revolution is the significant release of carbon dioxide into the atmosphere from burning fossil fuels such as coal and petroleum.
During the Industrial Revolution, humans started using coal as a fuel to power steam engines and later, the burning of petroleum increased with the introduction of automobiles.
These activities released large amounts of carbon dioxide, contributing to the rise in atmospheric carbon dioxide levels.
What molecule that is created during photosynthesis provides energy for cellular processes?
A)ATP
B)chlorophyll
C)oxygen
D)glucose
Answer:
(D) Glucose.
Explanation
I took the test for k12 and the answer is D
Glucose molecule that is created during photosynthesis provides energy for cellular processes.
What is photosynthesis?The process by which plants convert carbon dioxide, water, and sunshine into oxygen and sugar-based energy is known as photosynthesis.
Photosynthesis is essential to most life on Earth. Plants, algae, and some types of bacteria carry out the process by capturing solar energy to create oxygen and chemical energy stored in glucose (a sugar). herbivores get this energy from consuming plants, and carnivores get it from eating herbivores.
Plants absorb water and carbon dioxide from the soil and atmosphere during photosynthesis. Water is oxidized, which means it loses electrons, while carbon dioxide is reduced, which means it receives electrons, inside the plant cell.
Therefore, Glucose molecule that is created during photosynthesis provides energy for cellular processes.

The growing season of plants is primarily influenced by
Answer:
The growing season of plants is primarily influenced by temperature.
Explanation:
The temperature of their environment, along with their species-specific temperature requirements have major impacts on plant growth. Plants usually grow more quickly with an increase in their environmental temperatures.
However, extreme temperatures (beyond their maximum and minimum) can slow growth. This determines their corresponding growth season, which includes: a seasonal interval between spring and autumn; or an average number of days above the minimum temperature. Every plant species has a specific range of temperatures:
An optimal temperature- for the best possible growthA Minimum temperature- (or basal temp) the lowest temperature capable of triggering growthA Maximum temperature- the highest tolerable temperature capable of triggering growthE.g. Wheat's growing season requires sustained temperatures above 5°C.
To date a sedimentary rock layer between two igneous rock units, gologists use
radiometric dating and assume that the sedimentary layer's age _____.
Final answer:
Geologists use radiometric dating of igneous rocks above and below a sedimentary layer to bracket their age. Other methods, such as biostratigraphic correlation using fossils, also support the dating of the sedimentary layers.
Explanation:
To date a sedimentary rock layer between two igneous rock units, geologists use radiometric dating and assume that the sedimentary layer's age is bracketed by the ages of the igneous rocks above and below it. Using radiometric dating, they measure the decay of radioactive materials within the igneous rocks to determine their ages. Since sedimentary rocks can't be dated as precisely using radiometric dating—because this method dates the time of crystallization of minerals, not the time of sedimentation—geologists apply the principles of relative dating. These principles include the law of superposition, which states that in undisturbed stratigraphic sequences, the sedimentary layer in question must be younger than the rock beneath it and older than the rock above it.
Geologists use other methods such as examining fossil content for biostratigraphic correlation to help support the dating of the sedimentary layer. Fossils can be particularly useful in correlating sedimentary rock layers across different areas when they contain the same species known to have lived during a specific period.

A loss of species diversity in the oceans would MOST LIKELY result in a shortage of which of these?
A)
food
medications
minerals
D)
mountains
Answer:
A is the answer
Explanation:
Answer:
The correct answer is A) food
Explanation:
Species diversity indicates a total number of different species that live in a community. If the species diversity is more then the community contains more number of individuals of different species.
So if the number of individuals decreases in a species than the species diversity will decrease. In an ecosystem, one species is dependent on another species for its survival because a species present on upper trophic level consume the species of its lower trophic level.
So if there is a loss of species diversity in lower trophic levels in the oceans then it will result in a shortage of food for upper trophic level.
