Answer:
Viruses are classified into 4 groups based on their shape: filamentous, isometric , enveloped, and head and tail.
Many viruses attach to host cells to facilitate penetration of the cell membrane, allowing their replication inside the cell.
The virus core contains the small single- or double-stranded genome that encodes the proteins that the virus cannot get from a host cell.

According to the Baltimore classification system, Viruses are classified into seven classes on the basis of their morphology and function.
What is Virus?A Virus may be defined as a type of microorganism that consists of a nucleic acid molecule in a protein coat and infects cells and may cause disease.
Viruses are classified into seven classes, each of which has its own families of viruses and has differing replication strategies.
Class 1: Double-stranded DNA viruses.
This type of virus usually must enter the host nucleus before it is able to replicate. An Example is Adenoviridae.
Class 2: Single-stranded DNA viruses.
Such types of viruses replicate within the nucleus and pertain highly in vertebrates. An example is Circoviridae.
Class 3: Double-stranded RNA viruses.
Such types of viruses do not depend on host polymerases for replication. An example is Birnaviridae.
Class 4: Single-stranded RNA viruses (positive sense).
Such types of viruses have polycistronic mRNA which is translated into a polyprotein. An example is Flaviviridae.
Class 5: Single-stranded RNA viruses (negative sense).
Such types of viruses must be transcribed by viral polymerases into complementary forms. An example is Filoviridae.
Class 6: Single-stranded RNA viruses (positive sense) that replicate through DNA intermediate.
Such types of viruses use the enzyme reverse transcriptase to convert the positive sense RNA into DNA. An example is Retroviruses.
Class 7: Double-stranded DNA viruses that replicate through a single-stranded RNA intermediate.
Such types of viruses have a double-stranded gapped genome that is subsequently filled into a covalently closed circle that serves as the template for the production of viral mRNA. An example is the Hepatitis B virus.
Therefore, it is well described above.

The sputum (fluid coughed up from the lungs) of many smokers contain cells with mutations in the genes for p53. The smoking-induced mutations appear to be an early signal showing that cancer of the lungs will follow. What is the likely relationship between early p53 mutation and the development of lung cancer
Answer:
The correct answer would be - mutations in the p53 would prevent abnormal cells from dying by apoptosis.
Explanation:
P53 or tumor protein 53 gene is the gene that produces a protein that controls DNA repair and apoptosis in the cell cycle if there is an error in the DNA or cells growing abnormally therefore known as tumor suppressor gene.
If there is a mutation in this gene will prevent it from performing its function of DNA repair or stimulating apoptosis and then p53 would prevent abnormal cells from dying by apoptosis.
Thus, the mutation in P53 would lead to the growth or development of lung cancer.

A magazine published an article stating that drinking water obtained from waste water is harmful for health. Why is this information most likely to be incorrect? The article does not provide a scientific basis for the information magazines do not generally publish reliable scientific information drinking water has been obtained from recycled waste water since many years scientific tests show that drinking water obtained from waste water is pure and safe
Answer:
The correct answer is - the article does not provide a scientific basis for the information
Explanation:
Generally, Magazines publish articles with reliable information and sources that are universally accepted or have a scientific basis behind the information. It is already known that wastewater is recycled and purified before making it available for drinking.
In this article, there is no scientific basis behind the information as no scientific data mentioned or ignore test and practice in use from the years which is scientifically tested.

freely movable joint is also known as synovial joint why
Answer:
Why are synovial joints freely movable?
Diarthroses are freely movable articulations. ... The bones of a synovial joint are covered by a layer of hyaline cartilage that lines the epiphyses of joint ends of bone with a smooth, slippery surface that does not bind them together. This articular cartilage functions to absorb shock and reduce friction during movement.
Explanation:
please give me brainly got my answer from G00GLE so of course its correct hope i helped!!!
Answer:
Explanation:
Synovial joints (freely movable joints) allow us the free movement to perform skills and techniques during physical activity. Synovial joints have synovial fluid in the joint cavity that lubricates or 'oils' the joint so it moves smoothly. Synovial fluid is made by the synovial membrane.

Bart thinks mice exposed to microwaves will get stronger (maybe he's been reading too much Radioactive Man). You decide to perform this experiment by placing 10 mice in a microwave for 10 seconds. He compared these 10 mice to 10 other mice that had not been exposed. His test consisted of a heavy block of wood that blocked the mouse's food. found that 8 out of 10 of the microwave mice were able to push the block. 7 out of 10 of the mice without microwaves were able to do the same.
identify
1. control group
2. independent variable
3. dependent variable
4. what are some of the mentioned control variables?
5. what should bart's conclusion be?
Answer:
Control group = mice that had not been exposed
Independent variable = Mice receiving radiation
Dependent variable = Number of mice that are able to push the block of wood.
Control variables = Health of mice, mass of block
Radiation does not have effect on strength of the mice
Explanation:
In an experiment the variable which changes with respect to the other variable is called the dependent variable and the other variable is called the independent variable.
The control group is the group that does not receive treatment which is used to compare the effect of the treatment.
The control variable is another variable that must be held constant when performing the experiment.
Here the
Control group = mice that had not been exposed
Independent variable = Mice receiving radiation
Dependent variable = Number of mice that are able to push the block of wood.
Control variables = Health of mice, mass of block
It was found that 8 out of 10 of the microwave mice were able to push the block. 7 out of 10 of the mice without microwaves were able to do the same. This means that there was no significant difference hence, the conclusion drawn should be that radiation does not have any effect on their strength.
If transpiration didn't take place, would water be able to enter the roots of the plant? Explain your reasoning
Answer:
Yes
Explanation:
If transpiration do not occur water will enter the roots of the plants because water enter through the roots by osmosis and move to the xylem vessels after which it get to the leaves and it is lost by evaporation and transpiration. Transpiration is the process why by water is loss through the stomata opening of the leaves and this help in exchange of gases, reduction of excess water and help in plant growth.

Explain how the structures of plant tissues and organs are directly related to their roles in physiological processes.
Answer:
How the structures of plant tissues and organs are directly related to their roles in physiological processes.
o Plant organs are limited to roots, stems, leaves, flowers, fruit and cones.
o Physiological processes are limited to photosynthesis, cellular respiration,
transpiration, and reproduction.
o Plant tissues are limited to meristematic, ground, dermal and vascular tissues.
o Plant structures are limited to cambium, guard cells, phloem, seed, stomata and
xylem
Explanation: Hope this helps have a safe and happy new year
Roots, stalks, leaves, flowers, fruit, and cones are the only organs found in plants. Photosynthesis, metabolic processes, transpiration, and fertilization are the only physiological activities.
Plant and plant tissues:Photosynthesis and the movement of mineral-containing water ions are critical processes in the development of healthy plants. Plants have three primary structures or organs:
LeavesStemsRootsThey're made up of groupings of specialized tissues with structures that are tailored to the functions they do.
Adaptations are distinctive features that help plants survive in their specific settings. Plants rely on their specialized structures to provide their fundamental requirements, protect themselves from predators, and aid reproduction.

A girl is born with hemophilia. Her dad also has hemophilia, but her mother does not.
What genetic explanation can you provide as to why the girl
suffers from hemophilia?
answer:
So daughters get 2 X chromosomes from the mom and dad and if the dad has hemophilia the daughter would get it too and sons would not get because they get Y chromosome from their dad and hemophilia is found in the X chromosome because the X chromosome is the one that has the instructions for making the clotting factor proteins.
Explanation:
A father who has hemophilia has the gene and passes it on to his daughter because daughters get two X chromosomes, one from their mother and the other from their father. This is why daughters of men with hemophilia are called obligate carriers. Since sons only receive a Y chromosome from their father, they would not have inherited hemophilia.
Hope this make sense!
