In which of the following hydrogen bonds can be found?
A. Between cytosine and thymine in a DNA double helix
B. Between deoxyribose sugar and nitrogen base in a DNA nucleotide
C. Between deoxyribose sugar and phosphate group in a DNA nucleotide
D. Between purine and pyrimidines bases in a DNA double helix

Answers

Answer 1

Answer: C. Between deoxyribose sugar and phosphate group in a DNA nucleotide.

Explanation:

Hydrogen is a very important element in the planet due to the many uses of its compounds for example, water. Hydrogen is also very important to humans as it is integral to DNA formation.

Hydrogen bonds exist in the DNA nucleotide to ensure that different strands are connected to each other. These strands are composed of bonds between deoxyribose sugar and phosphate groups.

Describe the environmental conditions that extremophiles are able to live in. Describe the environmental conditions that extremophiles are able to live in. Extremophiles were microbes that could only live in conditions that prevailed early in Earth's history when environments had high temperatures and pressure and lacked oxygen. Extremophiles includes those microbes that thrive in very high-salt, high-temperatures, low-temperature, high-pressure, low-pH, or high-pH harsh conditions. Extremophiles can only survive in habitats where there are extreme changes in close proximity, such as hydrothermal vents at the bottom of the ocean, where water as hot as 300°C emerges and mixes with 4°C seawater. Extremophiles are able to tolerate extreme conditions found in space such as a near vacuum and temperatures in excess of 300°C or several hundred degrees below 0°C.

Answer:

Extremophiles includes those microbes that thrive in very high-salt, high-temperatures, low-temperature, high-pressure, low-pH, or high-pH harsh conditions.

 

Explanation:

Extremophilic organisms are life forms that can grow in extreme environmental conditions, such as the above mentioned. In general, extremophiles are prokaryotic organisms (i.e., archaea and bacteria), although there are some eukaryotic species that are considered extremophilic organisms. Extremophiles are classified into two main types: 1-microorganisms that live in extreme conditions and 2-microorganisms that have the ability to tolerate extreme environmental conditions. Extremophiles are extremely important both in basic and applied research. An example of this is the thermostable Taq DNA polymerase obtained from the bacterium Thermus aquaticus (an extremophile that lives in areas of high temperature and pressure), which is essential to carry out the Polymerase Chain Reaction (PCR).

how your innate immunity protects you from the pathogens you encounter.

Answers

Answer:

The innate immunity in living organisms protects them from the pathogens they encounter daily.

Explanation:

Pathogens are organisms such as virus, fungi, bacteria, protozoa, worms that causes diseases to its host.

For example, Avian flu is a strain or variant of the Influenza virus which predominantly causes a disease in birds such as chickens. The virus responsible for the Avian flu can be passed from birds to humans; when anyone comes in contact with a bird that is carrying the virus i.e a sick bird with Avian flu.

Homeostasis can be defined as a process through which a living organism maintains a steady or stable physical, internal and chemical environment ideal to enhance life and proper functionality.

Also, immunization can be defined as the process of boosting an individual's immunity or immune system against antigens (immunogen) which cause diseases by the administration of vaccines.

Basically, immunization helps to improve the functions of the antibodies, B cells, T cells etc.

If a person becomes infected with a pathogen, such as a virus. The internal stimulus that mainly takes place in order for their body to maintain homeostasis is that their core temperature increases. This is because pathogens such as a virus do not thrive or survive in a hot environment; they're naturally allergic to high temperature (heat).

Most of the ocean floor is a type of rock called basalt. At the edge of continents, this basalt erodes and becomes small particles. Over time, the particles are compressed and form what type of rock? A. Igneous B. Basinic C. Metamorphic D. Sedimentary

Answers

Answer: D. Sedimentary

Explanation:

Sedimentary rocks are formed overtime are different particles of sand, shells, pebbles and other fragments of materials form layers and harden into rock.

The particles are compressed and form sedimentary rocks in the ocean floor. Ocean floor is the bottom of the waterbody. Thus, the correct option is D.

What is Ocean Floor?

The seabed or ocean floor is the bottom of the ocean. All the floors of the ocean are known as 'seabed'. The structure of the ocean floor of the global ocean is governed by the plate tectonics.

Most of the parts of the ocean are deep, whereas the ocean floor is known as the abyssal plain. The seabed also known as the seafloor, ocean floor, and ocean bottom is the bottom of the ocean.

The ocean floor can be divided into three distinct regions which are the continental margins, abyssal plains, and the mid-ocean ridges. The ocean floor has rocks which are called basalt. Here, the basalt particles are compressed which forms the sedimentary rocks. Sedimentary rocks are formed by accumulation of minerals.

Therefore, the correct option is D.

how your innate immunity protects you from the pathogens you encounter.

Answers

Answer:

General defenses are the first line of defense and are collectively called: the Innate Immune System. This system is called "innate" because it is genetically encoded, the traits that protect us from infections can efficiently be transmitted to our offspring.The innate immune system recognizes molecular structures that are produced by pathogenic microorganisms. Microbial substances that stimulate innate immunity are often shared by different classes of microbes and are called molecular patterns associated with pathogenic microorganisms

Explanation:

The first defenses that external agents face when trying to penetrate the body are totally nonspecific and are made up of the anatomical, physical, chemical or biological barriers characteristic of each location, while some, such as temperature, are systemic. Between all they make up innate immunity. The importance of these barriers is reflected in the ease with which infections are acquired when one of them fails. Innate cell recognition systems are based on surface or intracellular proteins of epithelial cells, neutrophils, macrophages, and dendritic cells and on soluble cytoplasmic receptors. All these receptors are generally called PRRs (Pattern Recognition Receptors) and bind to PAMPs (Pathogen-associated Molecular Patterns) molecules expressed only by the pathogen (bacterial lipopolysaccharides, carbohydrates and lipoproteins, peptidoglycans, RNA, DNA, etc.). Innate immunity constitutes a less evolved and specific defense than the adaptive one, since the same mechanism (cells, soluble factors, etc.) acts against different agents. Furthermore, repeated exposures to a foreign molecule or agent elicit a similar response and with the same intensity in all of them; that is, it lacks immune memory. The fact that it is a less evolved and specific response is compensated by its speed, since it occurs in hours, and because its intensity is not linked to a previous contact with the foreign agent. Furthermore, its action is essential for the subsequent development of the adaptive immune defense, to which the agent must be exposed once these barriers have been overcome.

7.An experiment was conducted that showd the building blocks of life (amino acids) could indeed be formed by the combination of warm salt water, volcanic gases, and sparks of electricity.

Answers

Answer:

The most significant experiment performed to date on the formation of organic molecules remains that of Miller and Urey in 1952 when they sought to test the hypothesis of Oparin and Haldane that the organic building blocks of life emerged from a reducing atmosphere (Miller, 1953). Miller filled a flask with the four gaseous elements of the reductive atmosphere: methane, ammonia, hydrogen and water. He then passed electrical discharges through them to simulate lightning. After 125 h of the experiment, using the equipment available to him at the time, Miller identified several alpha amino acids contained within the residues.

A food development company is interested in making on-the-go powder-based snacks in which consumers can "just add water" before eating. During market tests there are complaints that the powder does not dissolve well in water.If you were a food scientist, how might you modify the formula so that it will more easily dissolve in water? Provide your answer in 1-2 complete sentences.

Answers

The correct answer to this open question is the following.

Although there are no options attached we can comment on the following.

I might modify the formula so that it will more easily dissolve in water in the following way. I would ask my scientist in the laboratory to modify the formula. To make the formula more soluble when it makes contact with water, the addition of polar hydrophilic side groups to the molecule will help the formula to be soluble.

That is why it is very important to do focus groups to taste the product before launching it commercially and send the product to the stands of supermarkets, pharmacies, or grocery stores. If it is not previously tasted, you could encounter many difficulties. Furthermore, the FDA requires the best quality of the product so you have to make sure it works as it says in your advertisement.

please help fast. How do both systematics and taxonomy relate to phylogeny?

Answers

Answer: “ Systematics is concerned both with Taxonomy, the naming and classification of life, and Phylogeny, the science and study of understanding the family tree of all life on Earth. ... Systematics, then is the classification of life according to its phylogenetic (evolutionary) relationships.” -http://palaeos.com/systematics/

Systematic is related to the study of the evolution of a species over time and the relationship between them. Taxonomy is the naming and classification of animals and plants. The phylogeny is the study of family trees of every species on Earth, Hence they all are related to each other.

What is taxonomy?

Taxonomy includes the study of naming and classifying animals and plants. By seeing the characteristic of a new organism, it is classified and put into kingdoms and groups.

Phylogeny and systematic are related to the evolutionary relationship between them, the family tree, and how an organism evolved over time.

Thus, Systematic has to do with the investigation of how a species changes over time and how they interact. The naming and categorization of plants and animals are known as taxonomy. Phylogeny is the study of family trees. These terms are related to each other.
