N a pond, tadpoles eat algae and fish eat the tadpoles. around the pond, grasshoppers eat grass and, at night, are preyed upon by bats. other bats eat the first that eat the tadpoles. in this community, the tadpoles are:

DNA backbone is made up of deoxyribose monomer sugars as the basic unit that are covalently connected in chains. Each deoxyribose sugar is a five (5)-carbon ring. The  5’ carbon covalently bonds with a phosphate while the 3’ carbon bonds to the next deoxyribose carbon ring. The 1’ carbon is covalently bonded to a nitrogenous base (either Adenine, Thymine, Cytosine, or Guanine ).

In DNA, Cytosine pairs with Guanine, and Adenine pairs with Thymine. In RNA, the same principle applies only that RNA has no Adenine base but Uracil. Therefore, Thymine pairs with Uracil while, similar to in DNA, Cytosine pairs with Guanine.

Covalent bonds occur in virtually all the bonds except between nitrogenous base pairs of opposite strands of DNA.

The central Dogma stipulates that DNA --à RNA--àProtein. During transcription, information on DNA is copied to messenger- RNA.  In eukaryotes messenger- RNA moves to the cytoplasm where it is then translated to protein by ribosomes.  In prokaryotes, since there is no nucleus, the mRNA is translated even as transcription continues.

Explanation:

Green Hydra Scientific name hydra viridissima, is one of the simplest animals among multicellular Celentéreos animals. It belongs to the Hydrozoans.

The green hydra has a simple cavity that communicates to the outside through the mouth, which is surrounded by tentacles. Nutrition is effected by the pressure of small animals such as tiny Crustaceans, larvae of Insects, among others, sometimes swallowing prey larger than itself. By touching the animal with its tentacles to an animal all the nematocysts are discharged at the same time, some inoculate the paralyzing substance they possess; while others are rolled over the victim's body. Once this happens the tentacles are responsible for driving the food into the mouth, where it enters the gastrovascular cavity. The food undergoes in that cavity an extracellular digestion motivated by the gastric juices segregated by the glandular cells that cover this cavity, in something similar to the digestion that takes place in the superior animals. Flagellated cells move nutrient fluid that is in the gastric cavity and seize the undissolved particles, which are encompassed by those cells and directed inside. This intracellular digestion is analogous to that performed by the Protozoa. Insoluble particles are expelled through the mouth's own opening.

The fluid in the glomerular capsule is like plasma but lacks significant protein. The glomerulus distinguishes itself from other body capillaries in that an efferent arteriole drains it and maintains a higher blood pressure, facilitating efficient blood filtration.

The fluid in the glomerular capsule (also known as Bowman's capsule) is similar to plasma except that it does not contain a significant amount of proteins. This is because the filtration membrane separates the blood in the glomerular capillaries, and the capsular space allows small substances such as water, ions, and glucose to pass through but blocks larger ones like proteins and blood cells.

The glomerulus differs from other capillaries in the body in two main respects. Firstly, it is drained by an efferent arteriole, which is unique because, in general, capillaries merge into venules, not arterioles. Secondly, the glomerulus has a significantly higher blood pressure than other capillaries due to its position between two arterioles (afferent and efferent arterioles). This high pressure allows for the rapid and efficient filtration of blood.

Answer:

Troposphere

Explanation:

The troposphere is the layer of atmosphere that contain four major greenhouse gases and therefore, is the site for the greenhouse effect. The greenhouse gases present in the lower troposphere are water vapor, carbon dioxide, methane, and nitrous oxide.  

These greenhouse gases trap the radiations reflected back by earth's surface during the night. These trapped radiations serve to increase the earth's atmosphere.

The time it will take for a 30-gram sample of Carbon-14 to decay to 3.75 grams is 16500 years. This conclusion is reached as 3.75 gram is 1/8th of the original 30 gram sample, corresponding to 3 half-lifes of Carbon-14 (each of 5500 years). Hence, 3 half-lives took place which equals to total of 16500 years.

The half-life of a radioactive substance is the time it takes for half of the atoms in a sample to decay. In this case, the half-life of Carbon-14 is 5500 years which means that every 5500 years, only half of the initial amount of Carbon-14 remains. We want to find the time it will take a 30 gram sample to reach 3.75 grams, which is 1/8 of the initial amount. Therefore, we need to consider 3 half-lives:

So, the total time taken would be 3 * 5500 = 16500 years (which comprises of three half-lives of Carbon-14).

The rooster's genotype is Ccii, carrying the colored allele without an inhibitor gene. The hen's genotype is ccII, carrying the white phenotype and the inhibitor gene causing her to appear white. All the offspring have the colored phenotype as they will get the colored allele from the rooster and a non-inhibiting allele from the hen.

In this scenario, the colored feathers in Leghorn chickens are dominant and represented by 'C'. The white feathers are recessive and are represented by 'c'. There is also a second gene, 'I', that inhibits the expression of color when its genotype is either 'II' or 'Ii' and gives these chickens a white phenotype. If a colored rooster was mated with a white hen and all the offspring were colored, the following genotypes of the parents and offspring can be inferred:

Rooster (Male parent): genotype 'Ccii', meaning he carries the colored allele (being dominant over white), but with not inhibitor gene.

Hen (Female parent): genotype 'cCII', meaning she carries the white phenotype but also has the inhibitor gene, causing her to appear white.

Offspring: All will have the phenotype of colored feathers (since the cross between Ccii and ccII will give colored offspring genotype of CcIi in all cases).

Estuaries are unique environments where fresh and salt water meet, creating a diluted saltwater habitat. They provide protected areas for the breeding and development of various marine species. The organisms found in estuaries have developed adaptations to cope with the varying salinity conditions.

The main characteristic of estuaries is that they are biomes where a source of fresh water, such as a river, meets the ocean. As a result, both fresh water and salt water are found in the same vicinity, and their mixing creates a diluted (brackish) saltwater. This makes estuaries unique and complex environments that host a variety of marine and terrestrial organisms.

Another specific feature of estuaries is that they act as breeding grounds and nurseries for various marine species such as crustaceans, mollusks, and fishes. These species have developed behavioral and physiological adaptations to cope with the rapidly changing salinity conditions that occur in estuaries. For example, many estuarine plant species are halophytes, meaning they can tolerate salty conditions. Furthermore, some mollusks and clams in this biome have adaptations that allow them to switch between aerobic and anaerobic respiration depending on the salinity and oxygen content of the water.

Estuaries are unique brackish biomes where freshwater and saltwater interact. They house and support various species, which have evolved specific adaptations to handle changing salinity levels. Key factors affecting estuaries' ecological dynamics include tidal shifts and flow rate of freshwater sources.

Estuaries are characterized by the unique intermingling of freshwater and saltwater, creating a brackish water biome where rivers meet the ocean. This environment serves as a protected area and breeding ground for various organisms, including the young offsprings of crustaceans, mollusks, and fish. The salinity in estuaries, which is influenced by the flow rate of freshwater sources and the daily tidal shifts, is a major factor affecting the types of organisms found here and their adaptations to survive.

Both plant and animal species in estuaries have developed various adaptations to deal with the changing salinity. Many estuarine plants are halophytes, which can tolerate salty conditions by filtering out salt from the water they absorb. Mussels and clams, for example, switch from aerobic to anaerobic respiration when exposed to low salinity and revert when high tide returns, increasing the salinity and oxygen content of the water.
