Answer:

The answer is B. Relative humidity percentage will be 50 %.

Explanation:

Relative humidity is the percentage of water vapors in the air at a particular temperature compared to the how much it can hold at that temperature. if the relative humidity is high (100%) we feel hotter than the actual temperature because water will not evaporate due to air saturation. in this case as the real feel is 108 F at 96 F the relative humidity will be 50 %.

Final answer:

To find the relative humidity based on the 'real feel' temperature of 108 degrees F and an air temperature of 96 degrees F, one would use a Heat Index Chart or calculator. However, without additional information on the actual humidity level, it's not possible to determine the exact relative humidity percentage from just these temperatures.

Explanation:

The question about calculating the relative humidity when the "real feel" is 108 degrees F and the temperature is 96 degrees F requires knowledge of the Heat Index and water vapor density. The Heat Index is a measure that takes into account the relative humidity and temperature to determine how hot it actually feels. To determine the relative humidity given these temperatures, one would typically refer to a Heat Index Chart, which correlates temperature and humidity levels with the perceived temperature. However, without knowing the actual relative humidity or having access to a Heat Index Chart, the exact relative humidity percentage cannot be determined from just the "real feel" and air temperature. Normally, the relative humidity can change as the temperature changes, if the water vapor density remains constant.

Answer:

D. trait formation due to behaviors

Explanation:

It is obvious to see that the three animals, cat, whale, and bat, have the same basic structure of their forelimbs, but also that they have developed differently and have taken a new shape. The reason for this is a trait formation due to behavior. The cats ancestors were terrestrial, and the cats have remained terrestrial, walking on their four legs, and having the same shape and function as their ancestors. The whales had similar forelimbs, but their ancestors started to move more and more in water. As they did, they needed more muscle power, but also greater width of the forelimb so that they can move more easily and more efficiently in the water. This behavior has gradually resulted in a flat, strong, peddle like forelimb. The bat too had similar forelimbs to that of the cat, but its ancestors started to try to fly. The process was gradual, and it started with jumping, then longer jumps, development of skin between the fingers, elongation of the fingers, thus provide more area for development of wider skin area. This has resulted in developing a light, wide, skin dominated forelimb with elongated fingers, providing flight for the bat.

Explanation:they depend n the fish in the everglades and the waterflow affetcs the way they get the fish

Answer:

Option B, building channels to control water flow in the Everglades

Explanation:

The nesting pattern of wood storks is highly dependent on the pre drainage condition of Everglades region.

However in Everglades region several canals, ditches and roads have been constructed in recent times due to which the drainage pattern and wetland fragmentation is disturbed through out the region. This has lead to the reduction in the nesting activity of Wood Stork across the Everglades which has ultimately caused reduction of wood stork population.

Hence, Option B is correct.

Answer:

Mass extinctions, Wegenerian cycles, and the emergence of new life forms

Explanation:

Answer:

The correct answer is mass extinctions, Wegenerian cycles, and the emergence of new forms of life.

Explanation:

Every geological period is featured by the occurrences of Wegenerian cycles, mass extinction, and the origination of novel forms of life. The boundaries of the majority of geologic periods are generally mass extinction periods and this mass extinction stimulates the formation of new forms of life.  

At the time of the geologic period, an array of tectonic activities plays an essential part as a consequence of the internal functioning of the Earth. The splitting of the continents takes place and arising of new landform at the plate boundaries takes place. This is termed as Wegenerian cycle.

Explanation:

So, that they can be compared to the mice who have been given vitamins.

Answer:

The good control would be if a mouse or mice who have given food without vitamin for ten days.

Explanation:

The good control of an experiment must remain equal or the same throughout in order to receive precise or accurate results. It is something that is used as an ideal of comparison for checking the end results of an experiment.

A mouse who have given food without equal or no vitamin for ten days would be a good control as it will help in comparing the weight with the ten mice who were given an equal amount of vitamin for ten days.

Thus, good control would be if a mouse or mice who have given food without vitamins for ten days.

Answer:

not sure i think a!

Explanation:

The correct answer is A The whale sharks teeth are an example of vestigial structures, if an inherited feature is no longer needed but also not harmful, there’s no evolutionary pressure to get rid of it

Explanation:

In biology, a vestigial structure refers to certain features such as organs or even behaviors that do not have a function or purpose in an organism but are still preserved usually because they do not represent a disadvantage for the organism. This occurs in the case of whale sharks teeth that despite being filter feeders, which means they feed on small organisms such as plankton they still have teeth, that they do not use for feeding or any other function, do not represent a harmful feature but might have a function in the past. Therefore, the best explanation for the teeth of whale sharks is that these are an example of vestigial structure, that was inherited but are not harmful and therefore they are still preserved as there is not an evolutionary pressure to get rid of them.

In the given diagram model of DNA replication, the labels are marked as follows:

A) Replication fork

B) DNA Polymerase

C) Sugar Phosphate Backbone.

The detailed explanation is as follows:

A) DNA Replication Fork:

The DNA replication fork is a critical structure formed during DNA replication, a fundamental process in cell division and genetic inheritance. It represents the point at which the DNA double helix unwinds and separates into two single strands, creating a Y-shaped structure. This unwinding and separation occur due to the action of enzymes called helicases, which break the hydrogen bonds between complementary base pairs.

At the replication fork, each single DNA strand serves as a template for the synthesis of a new complementary strand. DNA polymerases, the enzymes responsible for DNA synthesis, work at the replication fork. One strand, called the leading strand, is synthesized continuously in the 5' to 3' direction, while the other, the lagging strand, is synthesized in short fragments called Okazaki fragments, which are later joined by DNA ligase.

B) DNA Polymerase:

DNA polymerases are a group of enzymes that play a central role in DNA replication and repair. These enzymes are responsible for synthesizing new DNA strands by adding nucleotides to the growing DNA chain, using an existing template strand as a guide. DNA polymerases ensure the accurate replication of genetic information.

These enzymes work in a highly coordinated manner during DNA replication. DNA polymerases add nucleotides to the 3' end of the growing DNA strand in a 5' to 3' direction, complementary to the template strand. They require a primer, typically a short RNA or DNA sequence, to initiate DNA synthesis.

There are multiple types of DNA polymerases in cells, each with specific functions. DNA polymerase III, for example, is the primary enzyme responsible for replicating the bacterial chromosome during DNA replication.

C) Sugar-Phosphate Backbone:

The sugar-phosphate backbone is a structural component of the DNA molecule. It consists of alternating deoxyribose sugar molecules and phosphate groups, linked together by strong covalent phosphodiester bonds. The sugar-phosphate backbone runs along the outside of the DNA double helix and provides structural stability to the molecule.

The nitrogenous bases (adenine, thymine, cytosine, and guanine) project inward from the sugar-phosphate backbone and form the base pairs that connect the two DNA strands. The complementary base pairing between adenine and thymine (A-T) and between cytosine and guanine (C-G) ensures the specific and accurate coding of genetic information.

The sugar-phosphate backbone also plays a crucial role in protecting the genetic information stored within the DNA molecule by shielding the bases from chemical and physical damage. Additionally, it serves as the attachment point for various proteins and enzymes involved in DNA replication, transcription, and other cellular processes.

Answer:

B. Codon

Explanation:

Codon refers to nucleotide triplets of mRNA that serve to specify the amino acid sequence of proteins. There are total 64 genetic code that specify 20 standard amino acids found in proteins. All codon together make genetic code. For example: AUG is codon that specify amino acid "methionine". AUG codon also serve as initiation codon during initiation of protein synthesis.

A three-letter sequence of mRNA that encodes for specific amino acid is called a codon. Therefore, option (B) is correct.

A codon is a set of three nucleotides in mRNA that tells which amino acid should be added to a protein. There are 64 genetic codes that specify the 20 standard amino acids present in proteins.

The genetic code is made up of all the codons together. As an example: The codon AUG specifies the amino acid "methionine". The AUG codon can be used as an initiation codon when starting protein synthesis.

Mullerian mimicry

Explanation:

The Mullerian mimicry is a type of mimicry where two or more organisms that are not closely related have mimicked each other for the benefit of all of them. This occurs usually at species that are not closely related, but are similar in size and often in shape. Both species have a proper defense mechanism, being very toxic, containing some acids, being uneatable, but in order to avoid injuries or mistaken attacks, they have also developed a warning signal, usually manifested through their coloration. Both species develop the same type of coloration and patters, making them look almost identical. This is for the benefit of both species, as the predators that they have in common will avoid both species by thinking that it is only one species that is not good for eating, thus having it more easy for remembering and avoiding, especially when it comes to the younger individuals of the predators.

Answer:

False. Ornithology is study of birds and ichthyology is of bony fish

Ichthyology studies fish, while ornithology examines birds. Mammals are unrelated to either.

The fields of ornithology and ichthyology do not study mammals. Fish is studied by the field of Ichthyology, whereas birds are studied by Ornithology. Although they are classified as vertebrates, fish and birds are not mammals. Mammary glands and hair are characteristics of mammals.

Mammals are a class of animals that have glands for producing milk and hair. Mammals include creatures like dogs, humans, and whales.

In summary, Ichthyology examines fish, while Ornithology investigates birds. Neither has to do with animal kinds. Mammary glands and hair are two characteristics that set mammals apart.
