All of the above
Explanation:
Numerous virus can survive in extremely hot, freezing, extremely acidic, or extremely salty settings. Additionally, the viruses that infect such bacteria must be able to maintain their infectivity under adverse circumstances. Thus, option A, C, D is correct.
What are the unfavorable conditions for virus?Because they lurk inside cells, viruses present a significant challenge to the immune system of the body.
Antiviral drug resistance may appear as chronic or escalating viremia or illness despite treatment, due to prolonged antiviral drug exposure and continued viral replication brought on by immunosuppression.
When a virus ceases responding to an antiviral drug, it is said to have developed antiviral resistance. Antiviral medications become ineffective or altogether useless as the virus evolves.
Therefore, virus are resistant.

Which of the following statements is true? Group of answer choices All forms of life employ the same genetic code mRNA is the only type of RNA found in the living system A typical human liver cell has one set of chromosomes Organisms interact but do not affect their environment
Answer:
All forms of life employ the same genetic code
Explanation:
The genetic code refers to the set of rules that facilitates the translation of nucleotide sequences into amino acids sequences (proteins). mRNA is read in a group of three nucleotides called CODON, which specifies a particular amino acid. The totality of all codons makes up the genetic code.
However, one of the characteristics of the genetic cos is its UNIVERSAL nature. The genetic code is said to be nearly universal meaning that the genetic code is the same in almost all living organisms with few exceptions. For example, AUG codon encodes Methionine amino acid in all forms of life.
Hence, All forms of life employ the same genetic code is TRUE. Note that, tRNA and rRNA are other types of RNA found in living systems. Also, liver cells are diploid i.e. has two sets of chromosomes. Lastly, interacting organisms affect their environment
All the forms of life employ the same genetic code.
• It is true that all the forms of life exhibits the same genetic code, however, they do not possess similar genome.
• The set of rules used by the living cells is known as the genetic code.
• It is used to translate information encoded within the genetic substance, that is, mRNA or DNA sequences into the proteins.
• The genetic code is greatly identical among all the organisms and can be articulated in a simple table with 64 entries.
Thus, the correct statement is that all the forms of life employ the same genetic code.

How do oceans play a part influencing our Earth systems?
Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface.
Explanation:
Answer:
Well, it plays a part because it is our key to making our Earth called home... The earth is majority filled with water. It plays a part also by giving us water, and many much more things that require water...I can go on forever and say how it gives us food as well... if we never had water, we would never have veggies and crops to keep us alive...
Explanation:
(Don't take it from me... take it from Nature...)
A grassy meadow high in the Sierra Nevada Mountains of eastern California is known to support a variety of organisms. During the summers when grass is thick and lush, and wildflowers abound, butterflies take advantage of this abundant nectar source. Bears graze on the berries in shrubs at the edge of the meadow. Deer also forage at the edge of the meadow. In the early mornings, coyotes are known to prey on the squirrel and mouse populations that burrow into the meadow soil. A variety of birds prey on the butterflies and other flying insects, such as bees and wasps.
If the biomass of flowers that support the butterflies was known to contain 100,000 units of energy, and certain bird species were eating the butterflies that foraged on the flowers, what amount of energy, on average, could be expected to be transferred to the birds?
Group of answer choices
a)100
b1,000
c10
d10,000
e50,000
Answer:
b) 1,000
Explanation:
In a typical food chain as described in this question, flow of energy occurs from one organism to another when they feed/fed upon. As one organism feeds, energy gets transferred to it. However, only about 10% of the available energy in the lower trophic level gets transferred because majority of the energy (about 90%) is lost as heat during metabolic processes of the organism.
Hence, if a flower contains approximately 100,000 units of energy and is fed on by butterflies. 10% of 100, 000 = 10,000 units gets transferred to the butterflies.
Likewise, the butterflies gets fed on by certain bird species. 10% of the available 10,000 units of energy in the butterfly gets transferred to the birds.
= 10/100 × 10,000 = 1000 units of energy.

Explanation:
This is because a scientific theory is similar to a explanation.
Staphylococcus aureus (remember that an organism’s scientific name can also be written with the genus name abbreviated—in this case, S. aureus) is a bacterium, one of the groups of microorganisms. Although the different groups of microorganisms share some similarities, there are several important differences that distinguish each group. Drag each of the following statements to the appropriate bin to indicate whether it is a characteristic of bacteria archa fungi, or viruses.1. Derive nutrition from organic or inorganic sources or conduct photosynthesis2. Have cell walls that contain peptidoglycan3. Not typically associated with human disease4. Found in extreme environments5. Eukaryotic6. Can be unicellular or multicellular7. Cannot survive outside a host cell8. Can be seen only with an electron microscopeA. BacteriaB. ArchaeaC. FungiD. Viruses
Answer:
Viruses: Found in extreme environments. Cannot survive outside of a host cell, can only be seen with an electron microscope
Fungi: Obtain nutrition from organic or inorganic sources or carry out photosynthesis. It is not usually associated with human diseases. Eukaryote: It can be unicellular or multicellular.
Bacteria: They have cell walls that contain peptidoglycan. Found in extreme environments (via spores)
Explanation:
In the part of the answer, the answer was given by grouping the different characteristics of the microorganisms, classifying them into three groups.
Viruses are considered microorganisms that need the replicative machine to reproduce their RNA or DNA, this is how it is doubted whether they are living organisms or not.
Fungi belong to a very broad group of subtypes, but they all refer to the fungi kingdom, they are in the form of spores in the soil or in the air, those fungi that are considered pathogens for humans, such as the generators of histoplasmosis, or blastomycosis. Most fungi are not pathogenic to our body, so some are edible, such as yeast.
On the other hand, and finally we have bacteria, which are a family that is classified into many groups according to their genus and species, their shape is what determines their nomenclature, such as those coconuts, which are grouped together in a of bunch of grapes and are called thus streptococcus in synonymous to this method of colonization and form. Many bacteria are typical of our commensal flora or microbiota, others are not, thus generating opportunistic infections or severe infections.
What type of selection affects traits that influence an individual's chances to find a mating partner or be chosen as a mating partner?
Answer:
Sexual selection
Explanation:
It is sexual selection because it is a type of natural selection in which an organism or organisms acquire traits which help the individual to be choose as a mating partner or to have preference for a mating partner or for competition among one sex organisms in which a traits succeed.
Sexual selection can be intrasexual or or intersexual. Intrasexual is is competition between one sex of the same organism and intersexual is between sexes of different organism.
Suppose that you were discussing cell theory with someone who has little understanding of biology. Which object could you best use as an analogy to explain the evolutionary history of modern cells?
Answer:
evolution of human works
Explanation:
The cell theory states that all living forms are composed of cells. These cells are the basic structural units of all organisms and they evolved from pre-existing cells present in primitive living forms. From a biological point of view, the evolution of cells is similar to the evolution of human works, which were during the beginning of human civilization less specialized than in modern times. Likewise, somatic cells present in evolutionary recent multicellular organisms are capable of carrying out more complex functions than primitive cells present in unicellular organisms.

Regions of the body which require large surface area for absorption, such as the cells covering the inner surface of the small intestine, often have
Answer:
layers of cell membranes- micro villi
Explanation:
They are similar to cilia but shorter in length and diameter.They have average diameter of micrometer with average length of 2 micrometer
These are layers of cells membrane which protrudes or extended on the epithelial lining of the small intestine.They are microscopic in structure,and their major function is to increase the surface area of the small intestine for absorption of digested food substances. Therefore reducing volume while aiding the rapid movement of the digested food into the bloodstreams.
Aggregate of micro villi is called brush border on the surface of the small intestine. Their activity with the villi aids the increase in the surface area which leads to absorption of food substances
compare and contrast the cells of plant and animals

Carbon is an essential element for life how does its atomic structure allow it to form so many different molecules
Answer:
This is because Carbon has four valence electrons (tetravalent) which gives it the ability to form up to four bonds differently with different elements/compounds. This gives rise to the creation of lots of compounds.
Carbon as an element also has atoms which fits into most substances thereby creating different possible compounds with others such as in carbohydrates, proteins, lipids etc. This is what makes Carbon an essential element for life.

Organisms cannot make their own food without
cell membranes
cell walls
chloroplasts
Vacuoles
Answer:
The correct answer is - chloroplasts
Explanation:
Plants or autotrophs contain exceptional organelles considered chloroplasts that traps light and use it to use carbon dioxide and water into sugar and oxygen. Living organisms without chloroplasts can not make their own food.
Chloroplasts look like oval, flat circles. Like mitochondria, they also have two membranes. The whole organelle encased by the outer membrane. The inner membrane contains stroma, a thick fluid, which makes up the vast majority of the chloroplast's volume. Dispersed all through the stroma are piles of empty plates called grana that contain chlorophyll, which traps sunlight based on the intensity for use during photosynthesis.
