after staining what should be the color of vegetative cells

Answer:

Explanation:

This includes a decrease in the rate of maximal expiratory air flow (a decrease in FEV1 and the FEV1/FVC ratio) due to the increased resistance, and a reduction in forced vital capacity (FVC) correlating with the level of hyperinflation of the lungs.

Answer:

cornea

Explanation:

When light rays reflect off an object and enter the eyes through the cornea (the transparent outer covering of the eye), you can then see that object. The cornea bends, or refracts, the rays that pass through the round hole of the pupil.

Answer:

750

Explanation:

With the f1 generation all being red flowers we can conclude that Red is dominant (R) and white is recessive (r).

This leads to the f1 generation having Rr. If you breed two Rr together you get

1 RR

2 Rr

1 rr

75% of the f2 will have red flowers. So if you take 1000 and multiply it by .75 you will get 750

Approximately 750 flowers will be Red.

Answer:

B

Explanation:

The two loci did not assort independently.

In order to check for independent assortment or otherwise of the result from the cross, Chi-square is used to see if the result conforms with that of Mendelian standard of 9:3:3:1.

Phenotype           Observed f        Expected f               [tex]X^2[/tex] = [tex]\frac{(O - E)^2}{E}[/tex]

AB/ab                     391                  9/16 x 1584 = 891       [tex]\frac{(391-891)^2}{891}[/tex] = 280.58

ab/ab                     401                   3/16 x 1584 = 297     [tex]\frac{(401-297)^2}{297}[/tex] = 36.42

aB/ab                      406                  3/16 x 1584 = 297    [tex]\frac{(406-297)^2}{297}[/tex] = 40.00

Ab/ab                      386                   1/16 x 1584 = 99       [tex]\frac{(386-99)^2}{99}[/tex] = 832.01

Total [tex]X^2[/tex] = 280.58 + 36.42 + 40.00 + 832.01 = 1,189.01

Degree of freedom = 4 - 1 = 3

Tabulated [tex]X^2[/tex] at degree 3 freedom and 95% level = 7.815

The calculated [tex]X^2[/tex] value is more than the tabulated value. Therefore, we conclude that the outcome of the cross is not in agreement with Mendelian standard and hence, the A and B loci did not assort independently.

The correct option is B.

Answer:

Sense: Smell, Taste, Touch, Sight, Hearing

Explanation:

Answer:

touch, sight, hearing, smell, taste

Explanation:

Touch is thought to be the first sense that humans develop, according to the Stanford Encyclopedia of Philosophy. Touch consists of several distinct sensations communicated to the brain through specialized neurons in the skin. Pressure, temperature, light touch, vibration, pain and other sensations are all part of the touch sense and are all attributed to different receptors in the skin.

Sight, or perceiving things through the eyes, is a complex process. First, light reflects off an object to the eye. The transparent outer layer of the eye called the cornea bends the light that passes through the hole of the pupil. The iris (which is the colored part of the eye) works like the shutter of a camera, retracting to shut out light or opening wider to let in more light.

hearing sense works via the complex labyrinth that is the human ear. Sound is funneled through the external ear and piped into the external auditory canal. Then, sound waves reach the tympanic membrane, or eardrum. This is a thin sheet of connective tissue that vibrates when sound waves strike it.

Humans may be able to smell over 1 trillion scents, according to researchers. They do this with the olfactory cleft, which is found on the roof of the nasal cavity, next to the "smelling" part of the brain, the olfactory bulb and fossa.

The gustatory sense is usually broken down into the perception of four different tastes: salty, sweet, sour and bitter. There is also a fifth taste, defined as umami or savory. There may be many other flavors that have not yet been discovered. Also, spicy is not a taste.

Answer:

All organisms are composed of cells that share a structural organization and play roles in similar biological processes.

Explanation:

All living organisms can be grouped in terms of cellular organization, functioning, and structure. These features enable us to define them as “subjects” of life. Organisms share basic biological mechanisms such as, among others, growth, homeostasis, development, energy processing, reproduction, etc. Moreover, life is also defined by the presence of essential biomolecules such as DNA, RNA, proteins and lipids. Finally, the cell is considered to be the basic unit of every life form, and organisms may be formed by one (unicellular) or more cells (multicellular). The fundamental feature of the cell is the presence of a membrane that separates it from the external environment, thereby defining its internal environment.

Explanation:

The Fungi Kingdom is a kingdom composed, as the name says, of fungi, which are organisms represented by many species, among them: yeasts, mushrooms, molds, Penicillium and others. As you already know, fungi are eukaryotic and multicellular organisms (with the exception of yeasts).

The monera kingdom is the kingdom formed by bacteria and also has several species as members. Among these species we can mention the Lactobacilli, Escherichia coli, Rhizobium (nitrogen-nodulating bacteria, very important for the natural fixation of nitrogen in legumes), among others.

The kingdom of protozoa is very diverse and even has an organism that does not have any type of genetic, structural and morphological similarity, but in most cases, the members of this kingdom are heterotrophs, eukaryotic and unicellular organisms. An example of this is amoebas.

The animal kingdom is made up of all animals, the most diverse and populous kingdom. All animals belong to that kingdom, including fish.

Answer:

Innate immunity is defined as the first line of defense against infections and faster than adaptive immunity while adaptive immunity is second or third line of defense mediated by the T and B lymphocytes.

Adaptive immunity forms memory cells for the same antigen while innate immunity do not.

As shown in the graph below, when an antigen enter in the body for the first time, our immune system response with innate immunity and response immediately with several symptoms such as sneezing, swelling or redness et-cetra. Then after few days adaptive immunity forms which is mediated by the T and B lymphocytes by forming against the antigen.

Now if the body exposed to the same antigen again (Secondary exposure), the immune system shows amplified response as it has already formed memory cells against the antigen.

The reason why bacteria can infect a person very quickly is because of the process of  binary fission.

Binary fission is defined as the reproduction process that is found in prokayotes such as the bacteria.

The binary fission involves these steps:

The final stage which is the splitting of cells leads to the formation of many daughter cells of the parent bacteria cell which can eventually led to infection.

Answer:

The correct answer is - yes lactase action is exergonic.

Explanation:

Lactase is an enzyme located in the small intestine of mammals including humans, however it is produced by many organisms in their body. Lactase is an essential enzyme as it helps in the digestion of the whole milk by breaking down the lactose, sugar present in milk.

Exergonic reactions are the reaction that releases energy by the breaking of molecules in any reaction. Generally, catabolic reactions are exergonic lie lactase catabolizes the lactose present in milk and release energy.

Thus, the correct answer is - yes lactase action is exergonic.

Answer:

By using genetical and ecological approaches

Explanation:

Genetic variation is useful to study the diversity of the species and to understand both intraspecific and interspecific variation patterns. In genetics assays, two or more genetic sequences belonging to different organisms are compared in order to determine nucleotide differences (i.e., homology level) between the complete sequences, which enable to determine the evolutionary relationships between taxa.

Ecological diversity is associated with the variation of terrestrial and aquatic ecosystems. Ecological variation across species can be represented by different measures such as niche variation among individuals, the number of trophic levels, etc. Ecological variation patterns may affect the ecological dynamics of species and their communities, thereby being of vital importance for diversity classification studies.

Answer:

Carbon AND

DEATH

Explanation:

Carbon containing organic molecules derived from the remains of  dead plants and animals on the earth million of years ago, buried deep under  the sediment and rock layers are called Fossil fuels. Coal,oil,and natural gas are examples.

These underground deposits were formed million of years ago,due to the chemical reactions between  relatively underground  water molecules on one hand,and the  earliest mic organisms  viz algae,bacteria  which inhabited the earth other hand.These decomposition occurred around 540 to 65milion years ago.

However,some million of later chemical reactions in the soil leads to compression of these remains underground.The degradation leads to formation of the fossil fuel precursor called Kerogen. With time Geothermal heat transforms the kerogen precursor to fossil fuel.  some other kerogens are transformed to other natural gas,coal etc.

Answer:

1. b. Crista is s constituent part of mitochondrion.

2. c. Gobi complex and nucleus are separate structures with no particular relationship to each other.

Explanation:

The crista is an integral part of the mitochondria. As you already know, mitochondria is a cytoplasmic organelle. it has two members that delimit it, the outer membrane is completely smooth, however the inner membrane is composed of numerous folds, that are called crista, and that spread through the interior of the mitochondria. These crista have as main function to increase the surface of the inner membrane.

The Golgi complex is a cytoplasmic organelle, as is mitochondria. The nucleus, however, is a cell structure, it is totally separated from the golgi complex and there is no particular relationship between these two structures.

The golgi complex participates in the storage and distribution of substances in the cell, while the nucleus is responsible for housing and protecting genetic information.

Answer and explanation:

Active transport refers to a procedure, which withdraws substances from a cell against the concentration gradient. During the process, the molecules move from low concentration to a high concentration.  

The mechanisms of active transport need the application of the energy of the cell, generally in the form of ATP. If a substance needs to move within the cell against its concentration gradient, that is, if the substance's concentration within the cell is more than its concentration in the extracellular fluid, then the cell must utilize energy to move the substance.
