Answers

the arctic/polar biome
hope it helps

An animal with thick fur is best suited for tundra biome.

Tundra biome is a flat and treeless arctic biome that is characterized by low temperatures and very short growing seasons. The climate of the tundra biome is very harsh, windy and extremely cold for most part of the year. Animals with thick fur are best suited for tundra biome. The thick fur of animals is a special adaptation that functions as an insulator protecting animals from the harsh climate in the environment. The thick fur helps animals to retain their body heat, keeping them warm and reducing heat loss. Examples of animals with thick fur that can be found in the tundra biome include; Polar bear, Tundra and Arctic Wolves and Musk Oxen.

Answer: Sugars

Explanation:

The process by which the plants make food is photosynthesis. This is done in order to produce carbohydrates which is in the form of glucose when formed.

The potato is stored form of starch in the plant body. The sugars in the plants is first used then it is stored in the plant body for further use.

The starch in the plant body is stored at different places in the plant body. In the roots, stems and flowers.

D.
energy required to break the chemical bonds of the reactants

Answers

the energy required to break the chemical bond of the reactants
Final answer:

Activation energy is the energy required to break the chemical bonds of the reactants in a chemical reaction.

Explanation:

The correct answer is D. Activation energy is the energy required to break the chemical bonds of the reactants in a chemical reaction. It is the minimum amount of energy needed for a reaction to occur. Activation energy acts as a barrier that the reactant molecules must overcome to undergo a reaction and form products. For example, when wood is burned in a fire, activation energy is needed to break the bonds between the carbon and hydrogen atoms in the wood and allow them to react with oxygen to produce carbon dioxide and water vapor.

Pizza is the favorite food of about one-third the students.

In an attempt to save money, the lunchroom staff sent out student questionnaires to see which foods students preferred, and it was found that pizza was the favorite food of about one-third of the students who chose Option B.

What exactly is food waste?

The food is important for the animals as well as plants and other living individuals as it gives them energy when cells use the food in cellular respiration, and based upon the energy most of the work is done, such as body repair, cell division, growth, etc. As the population grows, the rate of food cultivation cannot keep up to feed everyone, so food waste must be avoided so that everyone gets the required amount of food.

Gonorrhea is an STD affecting anything related to throat, rectum and private body parts. Doxycycline is an antiobitic curing bacterial or protozoan infections. As for gonorrhea, CDC recommends a dose of ceftriaxone with 250g first, then 100mg of doxycycline or 1g of azithromycin orally twice a day for 7 days.
There are two ways of taking Doxycycline, directly ingesting the capsule or by opening the capsule and administering with applesauce. Due to its ability to cause abrasion in the esophagus, it should be taken with at least eight ounces of fluid. With the applesauce, it is important that the nurse measures the contents and ensure that the patient drinks the full glass of fluids.

What chemical is responsible for the initial breakdown of carbohydrates?

Answers

Carbohydrate molecules are broken down into smaller particles during digestion. Carbohydrate digestion starts in the mouth. The saliva in the mouth contain an enzyme called ptyalin. Ptyalin acts on the carbohydrate portion [starch] in the food and cause the initial breakdown of carbohydrate in the mouth.

Which characteristic of the genetic code lowers the likelihood of mutation?

Answers

Degeneracy

Degeneracy simply means that most of the amino acids produced during protein synthesis from DNA is coded by more than one codon. A codon is a sequence of 3 nucleotides that codes for a specific amino acid.

Because more than 1 codon can produce the same amino acid, the chances of having the synthesis of proteins affected by mutations (i.e. point mutations) is decreased. For example, if the codon with the nucleotide series GAA, which codes for the amino acid glutamate, becomes the codon GAG, the codon will still produce glutamate because the code is degenerate. 
Final answer:

Degeneracy of the genetic code is a key characteristic that reduces the negative impact of mutations by allowing similar amino acids to be encoded by multiple codons, which differ by only one nucleotide, thus maintaining protein functionality.

Explanation:

Characteristic of the Genetic Code That Lowers the Likelihood of Mutation

One characteristic of the genetic code that reduces the likelihood of mutation having a negative impact is degeneracy. Degeneracy means that multiple codons can code for the same amino acid. Often, these codons differ by only a single nucleotide. If a mutation occurs, changing one of these nucleotides, the amino acid coded for might remain the same, or it might change to a similarly behaving amino acid. This aspect of the genetic code helps maintain protein functionality despite mutations. Additionally, amino acids with similar chemical properties tend to be encoded by similar codons, which further helps to conserve protein structure and function in the event of mutations.

Moreover, the genetic code is unambiguous and universal, which are additional important characteristics that illustrate its robustness. Each codon corresponds to one specific amino acid (or a start/stop signal), and this unambiguity prevents confusion during protein synthesis. The universality of the genetic code across all known living organisms highlights a shared evolutionary origin and ensures consistency in how genetic information is translated into proteins.

A permanent increase in size and dry mass is known as what

Answers

A permanent increase in size and dry mass is known as growth. Growth is not to be confused with the word development, which typically means an increase in complexity. When someone or something experiences growth, it becomes larger. However, the growth does not necessarily have to be permanent. For example, if you get an ear piercing infection, it can cause your ear to swell/grow. When the infection goes away, your ear will shrink/go back to its regular size.

The mark of sexual maturation for a boy that is most comparable to menarche for a girl is

Answers

Deepening of the voice.

Final answer:

The mark of sexual maturation for a boy that is most comparable to menarche for a girl is spermarche, the first ejaculation, marking a significant milestone in a boy's puberty, usually around 13 to 14 years old.

Explanation:

The mark of sexual maturation for a boy that is most comparable to menarche for a girl is spermarche. Menarche marks the onset of menstruation in girls, typically occurring around the ages of 12 to 13 years old, and signifies a key point in sexual maturation and the ability to reproduce.

Similarly, spermarche, the first ejaculation, represents a comparable developmental milestone in boys, usually happening around 13 to 14 years old. This event indicates that the male's body is starting to produce viable sperm, marking a significant step in sexual maturation.

Both menarche and spermarche are influenced by various factors, including genetics, diet, and overall health, and they signify the body's entry into reproductive capability. While the onset and pace of these developments can vary widely among individuals, they are central components of puberty that signal the maturation of the body's reproductive organs.

The addition of a phosphate group to a substrate is called Phosphorylation. the enzyme that catalyzes this reaction is referred to as a kinase.

What is Phosphate group?

A protein kinase phosphorylates an amino acid residue by adding a covalently bonded phosphate group, which is a reversible post-translational alteration of proteins.

Protein phosphatases catalyze the process of dephosphorylation, which is the opposite of phosphorylation. Protein kinases and phosphatases control how proteins function by acting independently and cooperatively.

Serine, threonine, and tyrosine are the amino acids that are most often phosphorylated in eukaryotes. Prokaryotes and plants also frequently phosphorylate histidine (though it is now known to be common in humans).
