why don't all cells have a tail
Answer:
Explanation:
As microscopes improved, biologists discovered that all kinds of cells have beating tails. They are found not only on free-living “animalcules” and sperm, but also on the cells inside multicellular organisms.
What organisms use the carbon dioxide produced by animals
Answer:
It is produced by almost all living organisms (both plant and animal). It is given off, (exhaled) into the air every time we breathe. Even organisms without lungs or gills release carbon dioxide into the environment. This includes insects, plants, bacteria, etc.

how does the structure of a carbohydrate allow it to perform its function?
Answer:
Carbohydrates are organic molecules ONLY composed of carbon, hydrogen, and oxygen molecules. So, their structure would be just covalent bonds between the three elements, and most likely non-polar. They give out a lot of energy, and carbohydrates are also known as sugars. Most foods have them.

NAME 3 SIMILARTIES AND 3 DIFFERENCES BETWEEN EACH OF THESE ZONES (AT LEAST 1 ABOTIC AND 1 BIOTIC FACTOR FOR EACH)
Sublittoral Zone & Epipelagic Zone
Abyssopelagic Zone & Hadalpelagic Zone
Neritic Zone & Oceanic Zone
Bathyal Zone & Bathypelagic Zone
Euphotic Zone & Aphotic Zone
Answer:
Like terrestrial biomes, aquatic biomes are influenced by a series of abiotic factors. The aquatic medium—water— has different physical and chemical properties than air. Even if the water in a pond or other body of water is perfectly clear (there are no suspended particles), water still absorbs light. As one descends into a deep body of water, there will eventually be a depth which the sunlight cannot reach. While there are some abiotic and biotic factors in a terrestrial ecosystem that might obscure light (like fog, dust, or insect swarms), usually these are not permanent features of the environment. The importance of light in aquatic biomes is central to the communities of organisms found in both freshwater and marine ecosystems.
Explanation:
The ocean is categorized by several areas or zones (Figure 1). All of the ocean’s open water is referred to as the pelagic zone. The benthic zone extends along the ocean bottom from the shoreline to the deepest parts of the ocean floor. Within the pelagic realm is the photic zone, which is the portion of the ocean that light can penetrate (approximately 200 m or 650 ft). At depths greater than 200 m, light cannot penetrate; thus, this is referred to as the aphotic zone. The majority of the ocean is aphotic and lacks sufficient light for photosynthesis. The deepest part of the ocean, the Challenger Deep (in the Mariana Trench, located in the western Pacific Ocean), is about 11,000 m (about 6.8 mi) deep. To give some perspective on the depth of this trench, the ocean is, on average, 4267 m. These zones are relevant to freshwater lakes as well.
The ocean is the largest marine biome. It is a continuous body of salt water that is relatively uniform in chemical composition; it is a weak solution of mineral salts and decayed biological matter. Within the ocean, coral reefs are a second kind of marine biome. Estuaries, coastal areas where salt water and fresh water mix, form a third unique marine biome.
The intertidal zone, which is the zone between high and low tide, is the oceanic region that is closest to land (Figure 2). Generally, most people think of this portion of the ocean as a sandy beach. In some cases, the intertidal zone is indeed a sandy beach, but it can also be rocky or muddy. Organisms are exposed to air and sunlight at low tide and are underwater most of the time, especially during high tide. Therefore, living things that thrive in the intertidal zone are adapted to being dry for long periods of time. The shore of the intertidal zone is also repeatedly struck by waves, and the organisms found there are adapted to withstand damage from the pounding action of the waves (Figure 2). The exoskeletons of shoreline crustaceans (such as the shore crab, Carcinus maenas) are tough and protect them from desiccation (drying out) and wave damage. Another consequence of the pounding waves is that few algae and plants establish themselves in the constantly moving rocks, sand, or mud.
What is an example of absolute threshold in psychology?
Answer:
In hearing, absolute threshold is the smallest level of tone you can detect, considering you have normal hearing and there are no interfering sounds. For example, you might not be able to hear someone whispering from 20 feet away, but if that person speaks to a normal voice, it may reach your absolute threshold.

How dose the force of the car change as the mas of the car increases
Answer:
Increases.
Explanation:
According to Newton's Second Law of Motion:
F = ma
So, if we keep the acceleration constant:
F ∝ m
F is directly proportional to m, which means if we increase the mass, the force will also increase and vice versa.
Hence, If the mass of the car increases, Force acting on it also increases.

~AH1807How do ocean currents transport heat around the earth?
Answer:
Ocean currents act as conveyor belts of warm and cold water, sending heat toward the polar regions and helping tropical areas cool off, thus influencing both weather and climate. ... The ocean doesn't just store solar radiation; it also helps to distribute heat around the globe.

________ causes euphoria followed by agitation, and is the major opioid drug of abuse.
Heroin is an opioid drug composed of morphine, a natural alkaloid derived from extracts from the seeds of the opium poppy. It is for that reason that heroin is considered a semi-synthetic opioid.

Answer:
tRNA molecules bring a specific amino acid to the ribosome, according to the mRNA codon.
Explanation:
In the context of protein synthesis, an mRNA molecule contains the specific codons that encode the amino acids that will be part of the protein. The tRNA is in charge of bringing the amino acids to the ribosome, according to the specific information of the mRNA codons.

Every year, 25 km 3 of sand is deposited on a beach by a nearby river, and 28 km 3 of sand is removed by wave action. Is the size of the beach increasing or decreasing? Explain your answer.
If 25 km3 of sand is deposited on a beach yearly and 28 km3 of sand is removed by wave action, the size of the beach would be decreasing, not increase.
First, there is a need to understand that the size of a beach is a function of the amount of sand deposited into it. The more the sand deposited, the more the beach would increase in size.
In this case, 25 km3 of sand is deposited annually but 28 km3 of sand is washed away by waves. The net amount of sand deposited can be calculated by subtracting the amount washed away by waves from the amount deposited. Thus
Net sand deposited = 25 - 28
= -3 km3
Hence, the net amount of sand deposited annually is negative, meaning that the beach would decrease in size.

Why did Mendel need to grow two offspring generations (F1 and F2) to develop his law of segregation?
Answer:
Mendel formulated the law of segregation as a result of performing monohybrid cross experiments on plants. The specific traits that he studied exhibited complete dominance. Not all types of genetic inheritance, however, show total dominance. In incomplete dominance, neither allele is completely dominant over the other.
Explanation:
Hope this helps.
Mendel need to grow two offspring generations (F1 and F2) to develop his law of segregation because the first generation offspring had just one form of each trait. The second generation showed both forms of the trait due to segregation.
What is Law of Segregation?When an organism produces gametes, each gamete receives only one gene copy, which is chosen at random. This is defined as the law of segregation. A Punnett square can be used to predict the genotype (allele combination) and phenotype (observable traits) of the offspring from a genetic cross.
This law of segregation, called the second law of inheritance, states that during meiosis cell division (gamete formation), pairs of alleles separate from each other so that only one allele is present in each gamete.
Mendel formulated the law of segregation as a result of experimenting on monohybrid crosses on plants. The specific traits he studied showed complete dominance. However, not all types of genetic inheritance show total dominance. In incomplete dominance, neither allele is completely dominant over the other.
Thus, Mendel need to grow two offspring generations (F1 and F2) to develop his law of segregation because the first generation offspring had just one form of each trait. The second generation showed both forms of the trait due to segregation.
