Which of the following best compares viral reproduction to reproduction in other organisms?
A. Viruses do not contain genes that are replicated and passed on.
B. Viruses must commandeer the mechanisms of a host cell in order to reproduce.
C. Viruses and single-celled organisms use mitosis as a reproductive process.
D. Viruses can only reproduce asexually while other organisms have a choice.
Answer:
B. Viruses must commandeer the mechanisms of a host cell in order to reproduce
Explanation:
Virus is an organism that is incapable of replicating on its own without infecting a living host cell. A viral cell is dependent on a living host to replicate and express its genes. Hence, the infection cycle of a virus is its reproductive life cycle.
Other living organisms e.g plant, bacteria, fungi etc. have the ability to reproduce i.e. multiply on their own through asexual or sexual means. However, on the contrary, a virus must infect a living host, hijack the replicational abilities of the host cell in order to reproduce. Based on this, a virus employs a lysogenic or lytic cycle or both on its host to reproduce.

Scientists have been studying threats to coral reefs. The percent of reefs affected by various threats are shown in the figure below. A future global temperature increase may affect all categories on the figure. Predict which category would change the most from global temperature increases and propose a testable question that scientists could study.
a. The biggest effect will be on the far right column that includes thermal stress with a greater percentage of reefs falling into the low and medium threat categories. Scientists could test whether reefs that have greater fishing risk also have greater thermal risk.
b. The biggest effect will be on the far right column that includes thermal stress, with a greater percentage of reefs falling into the high and very high threat categories. Scientists could test whether reefs that have greater temperature changes have greater increases in watershed-based pollution.
c. The biggest effect will be on the far left column that includes fishing, with a greater percentage of reefs falling into the high and very high threat categories. Scientists could test whether increased fishing causes increased marine-based pollution.
d. The biggest effect will be on the far left column that includes fishing, with a greater percentage of reefs falling into the low and medium threat categories. Scientists could test whether reefs that have greater temperature changes have greater increases in fishing threats.
Answer:
It's B
Explanation:
Temperature rise will eventually end up putting coral reefs into the high threat categories, not fishing and DEFFINITELY not lowering their "risk" factor.
Coral reefs are the organisms of the aquatic ecosystem. The column includes the thermal stress that will be affected the most as the reefs fall into high and very high threats are huge. Thus, option B is correct.
What is the effect of thermal stress on coral reefs?Due to an increase in pollution and global warming, the oceans have heated up, which results in thermal stress and leads to coral bleaching and threat to the coral reefs.
The percentage of the very highly threatened, highly threatened, slightly threatened, and threatened reefs are seen majorly due to the thermal stress. Thermal stress is in increases amount due to oceanic warm-ups.
The thermal stress due to increased carbon dioxide activities and acidity leads to coral bleaching causes the destruction of the reefs and their endangerment.
Therefore, option B. the far right column labeled thermal stress has the biggest effect on the coral reefs.

Answer:
Water
Explanation:
This is actually a chemistry question but I'll answer it anyways
The definition of a chemical compound is " a chemical substance composed of many identical molecules composed of atoms from more than one element held together by chemical bonds. "
Compounds are homogenous, which means that they are evenly distributed and have 2 or more different elements from the definition
Therefore the answer is that water is a compound as its chemical make up is H2O.
Gold is made up of 1 element
Oxygen is made up of 1 element,
Hydrogen is made up of 1 element
Therefore these options are not viable since they do not contain 2 or more elements.

Answer:
1. Kingdom Protista
2. Kingdom Eubacteria
3. Kingdom Archaeabacteria
Explanation:
1. Kingdom Protista is one of the the six kingdoms. It consists of organisms called PROTISTS that are eukaryotic i.e. possess a membrane-bound nucleus and mostly single-celled (unicellular). Protists are eukaryotic organisms like plants, animals and fungi but their characteristics do not fit into any of these three eukaryptic groups. Protists include; algae, amoeba, etc.
2. Kingdom Eubacteria, as their name implies, are known as true bacteria. The constituent organisms of this kingdom are prokaryotic i.e. lack a membrane-bound nucleus and single-celled (unicellular). They possess a cell wall, in addition to their cell membrane, that is made up of PEPTIDOGLYCAN. Examples of organisms in this kingdom are Streptococcus, Bacillus etc.
3. Kingdom Archaebacteria were once grouped together with the true bacteria as kingdom Monera but were split because of their obvious differing characteristics. Archeans are single-celled prokaryotic organisms characterized majorly by their ability to live and thrive in extreme environmental conditions e.g hot conditions, anoxia conditions (no oxygen).

Answer:
Lymph nodes are found throughout the body and are a signal of a disease, infection, or problem if they become and remain swollen for long periods of time. Bacteria are pathogens that cannot be killed with antibiotics because they are non-living. They take over cellular organelles to replicate and spread. Because they are also eukaryotes with their own cell membranes and membrane-bound organelles, viruses are often difficult to combat with medicines. A cell signal called the FcϵRI receptor is produced by mast cells. These molecules cause more fluid to spread to an infected area. Lymphocytes are the types of cells that produce antibodies. All pathogens have unique identifying molecules on their surfaces called antigens. Antibodies bind to these and targeting the pathogen to be destroyed by the immune system. Fever is a non-specific response to disease, in which the body temperature rises. Respond to the following based on your reading.

When a paper cut breaks the skin, it introduces outside microorganisms into the cut. The body recognizes the break in the skin. Mast cells produce histamines, which cause more blood and lymph fluid to flow to the wound. This increased flow brings phagocytic white blood cells to the area, which destroy invading organisms until the blood can clot and the skin can heal over the cut, preventing more organisms from entering the body. If a cut is too deep or too wide, special care such as stitches and antibiotics could be needed to prevent infection.

What happens to electrons when pigments in Photosystem II absorb light? They become excited and break down the pigments to release ATP. They are pumped across the membrane into the thylakoid. They move through an electron transport chain to Photosystem I. They combine with oxygen and hydrogen to produce water.
Answer:
They move through an electron transport chain to Photosystem I.
Explanation:
High-energy electrons move through the electron transport chain from photosystem II to photosystem I. Energy from the electrons is used by the molecules in the electron transport chain to transport H+ ions from the stroma into the inner thylakoid.
Answer: They move through an elctron...
When light is absorbed by one of the many pigments in photosystem II, energy is passed inward from pigment to pigment until it reaches the reaction center. The high-energy electron is passed to an acceptor molecule and replaced with an electron from water.

The pedigree below tracks the presence of attached earlobes through a family's generations. Having attached earlobes is an autosomal recessive trait?
Answer:
Attached earlobes is an autosomal recessive trait.
Explanation:
Autosomal inheritance is the term used to describe characteristics passed on by genes that are not located on the X and Y chromosomes (the chromosomes responsible for determining the gender of individuals). The orela lobe genes are an example of genes that are involved in this type of inheritance.
This type of inheritance is called "autosomal recessive inheritance" when the individual received a recessive gene from his father and a recessive gene from his mother to form a characteristic. An example of this can be seen in individuals who have their earlobe attached.
Therefore, we can affirm that the attached ear lobe is a characteristic formed by recessive aautossomic inheritance.

Explanation:
In order to figure out the pedigree, you first have to do a punnet square- kind of like cross-multiplying. EX: For the first box: Aa x AA
For box one, we know that it is Aa, and not AA, because box 2 has to be AA.
We know that because Aa X Aa would give us some "aa" offspring which we do not see in the last generation (see 2nd pic). The only way to get no "aa" offspring is to have an AA X Aa cross.

which of the following is not a required process for the survival of animals?
Answer:
C. Movement
Explanation:
Movement is not a required process for the survival of animals.
This means that animals can survive without moving.
For example, during hibernation, a snake survives resting in a particular place without movement.
If a person's movement is confined to zero, the person can still survive, but if absorption of nutrients and oxygen stops, then the person shall die.

What are the categories for the Linnaean system? Which is the most specific? Which is the most broad?
Answer:
For first question the answer will be :
In the taxonomy of Linnaeus there are three kingdoms, divided into classes, and they, in turn, into orders, genera (singular: genus), and species (singular: species), with an additional rank lower than species. a term for rank-based classification of organisms, in general.
And for the second:
The species is the smallest and most exclusive grouping. It consists of organisms that are similar enough to produce fertile offspring together. Closely related species are grouped together in a genus. Linnaean Classification System: Classification of the Human Species.
While for third:
The broadest category in the Linnaean system is the kingdom.Animal Kingdom because Homo sapiens belongs to that kingdom. Other kingdoms include the Plant Kingdom, Fungus Kingdom, and Protist Kingdom.

A major freeway runs along a stretch of the ocean shore. Over time, scientists begin to
notice a decrease in the number of intertidal organisms. Which of the following is the most
likely cause of the problem?
O A. toxic waste spilled during accidents on the
road
B. runoff of oil and other chemicals from the
road
C. wastewater from the city across the
freeway
O D. Any or all of the above could be causing
the problem.
Answer:
D. Any or all of the above could be causing the problem.
Explanation:
Pollution has been said to have adverse effect on living organisms. In this question, a decrease in number of intertidal organisms has been observed. Since a major freeway runs along a stretch of the ocean shore, the most likely cause of the death of the intertidal organisms is the release of any form of toxic waste into the water body.
Oil pollutants causes death of living organisms by hindering the entrance of oxygen into the water body. It makes it difficult for oxygen, which is a requirement for life, to penetrate the water body. Hence, living organisms in the water body will suffocate and die.
Toxic wastes also causes the death of organisms when ingested in excess. Waste water causes deterioration in the oxygen content of the water body. Hence, any or all of the above options can likely cause the reduction in number of the intertidal organisms.
