Which structural data is normally used to classify mosses into the category Bryophyta?(1 point)
They are large.
They lack roots.
They produce flowers.
They produce seeds.
Answer:
They lack roots
Explanation:
The structural data which is normally used to classify mosses into the category Bryophyta is that they lack roots. Thus, the correct option for this question is B.
What are the characteristics of Bryophyta?The characteristics of the Bryophyta are as follows:
The plant body is mostly thallus-like, i.e. erect or prostate.They are generally attached or linked to the substratum by rhizoids. They significantly lack true vegetative structure. The plants are generally green and have chloroplast.They express an autotrophic mode of nutrition.Vascular tissues like the xylem and phloem are completely absent.It is known that Bryophytes include embryophytes like hornworts, liverworts, and mosses. These are very small plants that remarkably grow in shady or damp areas where there is an enormous amount of mud is present.
Bryophytes have no roots, leaves, or stems. This characteristic is the root foundation or evidence that is used to classify mosses into the category of Bryophyta.
Therefore, the correct option for this question is B.

Risk of toxicity is higher with fat- vitamins. True or False
Answer:
True
Explanation:
The fat-soluble vitamins, A, D, E, and K, are stored in the body for long periods of time and generally pose a greater risk for toxicity than water-soluble vitamins when consumed in excess. Eating a normal, well-balanced diet will not lead to toxicity in otherwise healthy individuals.

5. Ultimate source of brand new alleles in a population.
A. natural selection
B. mutation
C. genetic drift
D. gene flow
E. sexual selection
Answer:
1. D (In population genetics, gene flow is the transfer of genetic material from one population to another.)
2. C (Genetic drift may cause gene variants to disappear completely and thereby reduce genetic variation. It can also cause initially rare alleles to become much more frequent and even fixed. When there are few copies of an allele, the effect of genetic drift is larger, and when there are many copies the effect is smaller.).
3. A and also E (Individuals with inherited characteristics that allow them to best compete for limited resources will survive and have more offspring than those individuals with variations that are less able to compete. Because characteristics are inherited, these traits will be better represented in the next generation.)
4. D (Gene flow can increase fitness but if it happens in another environment, it decreases the adaptability. If alleles are advantageous, the offsprings' inheritance increases.
5. B (Mutations are the main source of alleles)

Explanation:
is a chemical substance that is produced in substantial quantities, and is reasonably expected to be released in to the environment in substantial quantities a risk trigger, standard trigger, or an exposer trigger?
Means that the EPA has made a determination that a chemical or biological agent may present an unreasonable risk both in toxicity and exposure.
a. exposer trigger
b. standard trigger
c. risk trigger
Answer:
c-risk trigger
Explanation:
The Risk Evaluation process is the second step, following Prioritization and before Risk Management, in EPA’s existing chemical process under TSCA. The purpose of risk evaluation is to determine whether a chemical substance presents an unreasonable risk to health or the environment, under the conditions of use, including an unreasonable risk to a relevant potentially exposed or susceptible subpopulation. As part of this process, EPA must evaluate both hazard and exposure, exclude consideration of costs or other non-risk factors, use scientific information and approaches in a manner that is consistent with the requirements in TSCA for the best available science, and ensure decisions are based on the weight-of-scientific-evidence.

Which statements about wells are true? Check all that apply.
Wells bring groundwater from the unsaturated zone to the surface of the water.
Wells need to be drilled below the water table.
If water is pumped from a well too quickly, the well may run dry.
Water from wells is generally not safe to drink.
Water gushes from artesian wells due to pressure.
Answer:
Wells need to be drilled below the water table.
If water is pumped from a well too quickly, the well may run dry.
Water gushes from artesian wells due to pressure.
Explanation:
The statements that assert a true claim regarding the wells would be as follows:
b). Wells need to be drilled below the water table.
c). If water is pumped from a well too quickly, the well may run dry.
e). Water gushes from artesian wells due to pressure.
The above statements offer appropriate claims regarding the wells that they are required to be penetrated down the water table because it assists in striking the water from the lower levels as well. The next statement asserts that water must be transported from wells in a hurry because it can impact the yielding ability of the wells.The streaming of water from the artesian wells is primarily because of the pressure as it helps in the release of the water effectively.Thus, options b, c, and e are the correct answers.

In what ways can the use of statistics help in improving mental health services? Could the use of statistics cause potential misunderstandings of mental health services? How can you avoid any such misunderstandings?
Myths, misunderstandings, and negative stereotypes and attitudes surround mental illness. These result in stigma, discrimination,and isolation of people with mental illness, as well as their families and carers.
----------------------------------------------------------------------------------------------------------------
Are mental illnesses a form of intellectual disability or brain damage?
No. They are illnesses just like any other, such as heart disease, diabetes, and asthma. Yet the traditions of sympathy, support, and flowers given to people with physical illnesses are often denied to those with a mental illness.
Are mental illnesses incurable and lifelong?
No. When treated appropriately and early, many people recover fully and have no further episodes of illness.
For others, mental illness may recur throughout their lives and require ongoing treatment. This is the same as many physical illnesses, such as diabetes and heart disease. Like these other long-term health conditions, mental illness can be managed so that individuals live life to the fullest.
Although some people become disabled as a result of ongoing mental illness, many who experience even very major episodes of illness live full and productive lives.
Are people born with a mental illness?
No. A vulnerability to some mental illnesses, such as bipolar mood disorder,can run in families. But other people develop mental illness with no family history.
Many factors contribute to the onset of a mental illness. These include stress, bereavement, relationship breakdown, physical and sexual abuse, unemployment,social isolation, and major physical illness or disability. Our understanding of the causes of mental illness is growing.
Can anyone develop a mental illness?
Yes. In fact, as many as one in five Australians may develop a mental illness at some stage in their lives. Everyone is vulnerable to mental health problems.
Many people feel more comfortable with the notion of having 'a nervous breakdown' rather than a mental illness. However, it is important to talk openly about mental illness, as this reduces the stigma and helps people to seek early treatment.
Are people with mental illness usually dangerous?
No. This false perception underlies some of the most damaging stereotypes. People with a mental illness are seldom dangerous. Even people with the most severe mental illness are rarely dangerous when receiving appropriate treatment and support.
Should people with a mental illness be isolated from the community?
No. Most people with a mental illness recover quickly and do not even need hospital care. Others have short admissions to hospital for treatment. Improvements in treatment over recent decades mean that most people live in their communities, and there is no need for the confinement and isolation that was commonly used in the past.
A very small number of people with mental illness need hospital care,sometimes against their will. Improvements in treatment are making this less and less common, and fewer than one in a 1000 people are treated this way.

1. Which of the following scenarios would not prompt the cell to start dividing? A. a bone elongating during puberty B. tissue healing after an injury C. stretching of a cell to allow for more fat storage
Answer:
I think the answer is C
Explanation:
The scenario that would not prompt the cell to start dividing is the stretching of a cell to allow for more fat storage.
What do you mean by Cell division?Cell division may be defined as the process by which a parent cell divides into two or more daughter cells.
The stretching of a cell to allow for more fat storage is usually done by the process of cell growth, but not by the process of cell division.
Therefore, the scenario that would not prompt the cell to start dividing is the stretching of a cell to allow for more fat storage.

Marine biologists have determined that when a shark detects the presence of blood in the water, it will swim in the direction in which the concentration of the blood increases most rapidly. Based on tests conducted by the biologists, the concentration of blood (in parts per million) at a point P(x,y,z) on the surface of sea water is approximated by
Blood concentration is approximated by the distance from the source.
The concentration of blood at a point P(x,y,z) on the surface of sea water is approximated by the distance from the source where the blood moves. Point x is the place where the concentration of the blood is the highest because at this point the source of blood present.
At point y, the concentration of the blood is lower as compared to point x but higher than point z, while on the other hand, at point z the concentration of blood is the lowest due to its presence farther from the source so we can conclude that blood concentration is approximated by the distance from the source.

Deposition is the geological process in which sediments, soil and rocks are added to a landform or landmass. Simply when layers of eroded material pile to create new landforms. For example, coastal deposition is how beaches are formed.
The geological process of deposition involves the addition of sediments, soil, and rocks to a landform or landmass. when eroded debris is piled up in layers to produce new landforms.
What is deposition?A deposition is testimony made under oath and taken down in writing by an authorized officer of the court, typically in an out-of-court setting and before trial.
Depositions are usually taken from key witnesses, but can also involve the plaintiff or defendant, to give the involved parties a fair preview of all the evidence.
The individual making the deposition is known as the deponent and false statements can carry civil and criminal penalties.

What make Eukaryotic cells different from Prokaryotic Cells?
Group of answer choices
Eukaryotic cells have membrane bound organelles and more complex structure
Eukaryotic cells do not have a nucleus and are unicellular
Eukaryotic cells all have cell walls and include bacteria and plants
Eukaryotic cells are mainly bacteria
Answer:
Eukaryotic cells have a membrane bound organelles and more complex structure
Explanation:
A bacterial cell usually contains a single loop of DNA that is located in the cytoplasm of the cell and is not surrounded by a nuclear membrane. Some bacteria have additional loops of DNA called plasmids. Plasmids can be used for genetic engineering because DNA from other organisms can be spliced into a plasmid loop. For example, scientists in the late 20th century discovered a way to insert the portion of human DNA that codes for the protein insulin into plasmid E. coli bacteria. Which statement best explains why these genetically modified bacteria have been useful to society?
A. Human diabetics are now more resistant to bacteria
B. The bacteria are resistant to human diabetics
C. The bacteria can now make their own insulin
D. the bacteria are used to produce cheap insulin.
Answer: A is the correct answer.
because for the treatment of one type of diabetes insulin should be provided but isolation of insulin and production is so costly.
but as DNA recombination has developed we can use bacterial replication system to produce insulin. they replicate very fast so large amount of insulin will be produced and then it can isolated.
but we also know that insulin of bacteria needs some modification before it can be used in human.
