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).

sexual selection or separation of two groups that caused isolation of one group and then it will breed more specific organisms.

Explanation:

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.

Explanation:

A benefit of the Endangered Species Act is to restore balance to ecosystems.

The Endangered Species Act refers to the law implemented for the protection of biodiversity by a country. Its purpose is to prevent the extinction of at-risk plants and animals and to increase their population.

So we can conclude that a benefit of the Endangered Species Act is to restore balance to ecosystems.

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.

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.

Answer:

The plane will be moving forward at 420 m/hr

Explanation:

The plane is traveling at 500 m/hr but there is 80 m/hr acting against it so you take away 80 from 500 which is 420.

Using two heterozygous tall pea plants, so Tt is the genotype.

       T        t    <---- alleles from parent one

T      TT    Tt

t       Tt      tt

^alleles from parent two on the left

Results:  TT, Tt, Tt, and tt

Genotype ratio:  1/4 TT, 1/2 Tt, 1/4 tt

Phenotype ratio: T is dominant over t, so 3/4 tall and 1/4 short pea plants

Answer:

3. The region of Earth => away from the sun.

Explanation:

In the summer months, the northern half of the Earth, where we live, tilts towards the Sun. The seasons are caused as the Earth, tilted on its axis, travels in a loop around the Sun each year. Summer happens in the hemisphere tilted towards the Sun, and winter happens in the hemisphere tilted away from the Sun. This means we get more sunlight, making the days longer.

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.

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.

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).

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.
