Which of the following medications is a parasympathetic bronchodilator?
A. Ipratropium
B. Albuterol
C. Alupent
D. Bronkosol
Answer: Option A.
Ipratropium
Explanation:
parasympathetic bronchodilator medications block the parasympathetic nerve reflexes that ensures the constrictions of air pathways which make it to be opened.
Ipratropium is a drug use to open or close lungs airways for treatments of pulmonary diseases or asthma
Ipratropium is a parasympathetic bronchodilator because it's causes the dilation of lungs airways which is a Blocking cholinergic receptors which will reduce the production of cyclic guanosine monophosphate causing dilation or decrease in lungs airways which result in a decrease or reduction in lungs smooth muscles contractions.

What aspect of chromosome behavior most clearly accounts for Mendel's law of segregation?
A. movement of sister chromatids to opposite poles at anaphase 2 of meiosis
B. movement of homologous chromosomes during prophase 1 of meiosis
The given question is incomplete as the group of choices lack the correct answer, however, the correct group of choices are as follows:
A. Movement of sister chromatids to opposite poles at anaphase II of meiosis.
B. Movement of homologous chromosomes to opposite poles at anaphase I of meiosis.
C. Crossing over between homologous chromosomes during prophase I of meiosis.
D. Replication of chromosomes prior to meiosis.
E. Independent alignment of different homologous pairs on the metaphase I spindle.
Answer:
The correct answer is : Movement of homologous chromosomes to opposite poles at anaphase I of meiosis.
Explanation:
The Mendel's law of segregation says that during formation of gametes the copies of genes segregate from each other so each gamete has equal and only one allele of the gene.
This behavior of homologous chromosome can be seen in anaphase I in meiosis, responsible for the segregation of copies of allele into different copies.
Thus, the correct answer is : Movement of homologous chromosomes to opposite poles at anaphase I of meiosis.
why virus, virions, prions have no place in five kingdom classification
Hey, there!!
There is no place for virus, virions, prions in kungdom classification. The reason is they show both living and non living characters, which don't define them whether they are living beings or non living things.
As in 5 kingdoms, the only living organisms are classified.
Kingdom Monera mostly deals with the organism which contains prokaryotic cells.Kingdom Protista deals with the organism which have eukaryotic cells.Kingdom Fungi deals with various fungal organism. Kingdom Plantae deals with various type of plants. Kingdom Animalia deals with various type of animals.So, you can see that there is non of the kingdoms which deals with the organism which have similar characteristics like viruses, virions and prions.

a phosphate group.
(5 Points)
Carbohydrates
Proteins
Lipids
Nucleic acids
Answer:
Nucleic acids
Explanation:
Nucleic acids are one of the the four major biological molecules in living systems (the other three being; carbohydrate, protein, and lipids). Nucleic acid is a biological polymer that is made up of monomeric units called NUCLEOTIDES.
Nucleotides, are monomers of nucleic acids that consists of a 5-carbon sugar (ribose or deoxyribose), nitrogenous base (Adenine, Guanine, Cytosine and Thymine/Uracil) and a phosphate group (PO34-). Ribonucleic acid (RNA) are deoxyribonucleic acid (DNA) are the two types of nucleic acids.
Mr. Toowise was having a difficult time getting his students to get good grades on quizzes. He was trying to think of a way that he could positively reward his students. He read an article that said that lab rats that were rewarded with sunflower seeds ran through a maze faster than rats that were not rewarded with sunflower seeds. Mr. Toowise stated, "I think that the more sunflower seeds I promise my students, the better they will do on a quiz." He divided the class into three groups. Group one was promised zero sunflower seeds if they did well on the next quiz. Group two was promised 25 sunflower seeds if they did well on the next quiz. Group three was promised 50 sunflower seeds if they did well on the next qutz. Group one received an average of 70% on the quiz. Group two received an average of 73% on the quiz. Group three received an average of 71% on the quiz. He looked at his results and concluded that the amount of sunflowers promised to students does not effect their quiz scores.
Using the information provided in the scenario above, fill in the data table below
1. Hypothesis: ___________
2. Dependent Variable: __________
3. Independent Variable: ___________
4. Constant Control Group _____________
5. Experimental Group:_____________
Answer and Explanation:
1. Hypothesis: The more sunflower seeds the students get, the better they will do on a quiz.
2. Dependent Variable: Responding variable refers to the dependant variable, which response depends on any change in the independent variable. A change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. In the exposed example, the dependent variable is the response of each group to sunflowers seeds expressed as their grades on quizzes.
3. Independent Variable: number of sunflower seeds. Manipulated variable refers to all the variables in an experiment that provoke a response in another variable. They are also known as independent variables. The researcher can change these variables to see what changes it implies in an object, process, trait, or anything that depends on them. In the exposed example, the researcher manipulates the number of sunflower seeds promised to each group.
4. Constant Control Group: Group 1, which does not receive any sunflower seeds. The election of a control group is essential in an experiment. Its principal purpose is to allow the discrimination of the results obtained by the treatment in the study, in this case, the provision of sunflower seeds, from the results that might be a consequence of other factors. The control group must be selected from the same population of the treatment group. All groups must be similar in every variable that might influence the results, except for the study treatment
5. Experimental Group: Groups 2 and 3, that received different amounts of seeds.
what is the special life force in the air called that people used to think created microbes?
Answer:
spontaneous generation
Explanation:
Spontaneous generation is the myth that organisms could originate without the need to have descent from similar organisms (i.e., created spontaneously from the dust). This belief stated that organisms could arise from nonliving material. Louis Pasteur conducted experiments in order to show that this belief was false and thus confirm the theory of biogenesis, which states living organisms can be only generated by the reproduction of similar living organisms. Pasteur showed that microorganisms could not be developed in isolated sterilized tubes, but they could be developed in open tubes, thereby showing that reproduction (biogenesis) is the only source of living organisms.

Honeypot ants (genus Myrmecocystus) can store liquid food inside their expandable abdomens. Consider other ants you are familiar with, and list how a honeypot ant exemplifies three key features of life: adaptation, unity, and diversity
Explanation:
When the environment becomes too hostile to aid the search for food (that is, dry season), the honeypot ant which can be referred to as repletes shows adaptation to its environment with the intelligent ability to store liquid food inside its abdomen. Their expandable abdomen serve as “living larders” for their entire colony because they are storage vessels.
It exemplifies unity because during a dry season, nutrients become more scarce. Very few flowers blossoms, and fewer insects will approach the colony which means less access to food. Honeypot ants turn to their living larders, which would have swollen to the size of grapes.
When the colony is in need of nutrient-rich liquids, a worker ant will stroke a replete’s antennae. This signals the replete to regurgitate the liquid. A worker can eat the liquid itself, or carry it to another member of the colony.
It exemplifies diversity because it is different from other ants in its ability to store liquid food in its expandable abdomen. Many insects store sweet liquid for later use. For example, honeybees usually stores liquid in their combs. Honeypot ants, are the only insects to store the liquid in their own bodies.
Honey pot ants or honey ants are the types of worker ants. It exhibits adaptation to the surrounding by storing the food in its abdomen region and shows unity and diversity.
What are the features of Honeypot ants?Honeypot ants belong to the genus Myrmecocystus is an arthropod and stores food like honey in the abdomen to the point of swelling and are 3 - 5 mm long.
They show adaptation when the environment becomes hostile and the food becomes scarce. They store the liquid food content in their abdomen and this swelled stored food of the abdomen acts as the living larders for the other ants of the colony.
Honeypot ant exemplifies the unity as during scarcity of food in off-seasons then the ants use their stored food or the larder to nourish the other ants of the colonies.
They are the tomb of the diversity as different from the other ants they store food in their own body rather some places of living like honey bees stores honey in the hives.
Therefore, honeypot ants show adaptation, unity and diversity.

Why isn't movement considered a characteristic of all life?
Answer:
not all living things move
Explanation:
Animals which are living things have the ability to move as well as microrganisms however, plants and certain microrganisms do not have these abilities and yet are still living.
Answer:
Technically, all living things move in some way.
Different animals, like humans, dogs, and goats, can walk and run. Marine animals can swim and dive. Birds and some insects can fly around.
Plants can move, just not the same way animals can. For example, a sunflower will turn to face towards the sun. Although, plants don't have the ability to move from one place to another, or locomotion.
So, movement can be considered a characteristic of life, but locomotion is not. Plants and other living organisms cannot get up and move from one spot to another spot.
Earth’s rotation is slowing over time. Billions of years from now, it is expected that Earth will take 47 days to make one rotation instead of the current 24 hours. How might this change the temperatures on Earth?
Answer: Due to a transfer of Earth's rotational momentum to the Moon's orbital momentum as tidal friction slows the Earth's rotation. That increase in the Moon's speed is causing it to slowly recede from Earth (about 4 cm per year), increasing its orbital period and the length of a month as well. In orbital mechanics, a gain in speed results in a higher orbit. The slowing rotation of the Earth results in a longer day as well as a longer month. Once the length of a day equals the length of a month, the tidal friction mechanism will cease. That's been projected to happen once the day and month both equal about 47 days, billions of years in the future. If the Earth and Moon still exist, the Moon's distance will have increased to about 135% of its current value.
