Water is denser than isopropanol, so the water layer will always be below the isopropanol layer if they are both in the same container. What does this tell you about the make-up of the pigments for each specimen?
Answer:
One is polar and the other is non-polar.
Explanation:
The makeup of both water and isopropanol is different from each other due to their polar nature. Water is a polar substance means that it makes poles i.e. positive or negative while on the other hand, isopropanol is non-polar substance so due to this reason water and isopropanol make different layers. If both are polar or nonpolar substances so they will able to mix with each other.

While studying the cells of a newly discovered fungus, you notice that its organelles resemble those of most eukaryotes, but some of their shapes are a little different. Although you're pretty sure you can identify each organelle, you analyze its chemical composition just to make sure. One organelle is shaped like a ball, and it is composed of proteins, membranes, and nucleic acids. That organelle is most likely the
Answer:
nucleus
Explanation:
The organelle would most likely be the nucleus.
The nucleus happens to be a membrane-bound organelle that is somehow round in shape. It houses most of the genetic components of the cell, including proteins and nucleic acids in the form of DNA.
Fungi themselves belong to the eukaryotic category of living organisms and as such, every fungus cell is expected to have a nucleus and other membrane bound organelles such as mitochondrion.
Hence, the organelle would most likely be the nucleus of the fungi cell.
Blood tests can be used to check a person’s blood glucose and hormone levels. The tabular column given below shows the result of two blood tests carried out on three people to check their blood glucose levels. Person 1 is healthy.
a.Compare the glucose levels of person 1 with the glucose levels of person 2 after fasting for12 hours.
b.Compare the glucose levels of person 3 with the glucose levels of person 1, 2 hours after drinking 75g glucose.
c.Person 3 cannot produce the hormone that controls blood glucose levels. State the hormone that person 3 cannot produce.
Pic is the table to refer.
pls answer it is urgent
Answer:
See the answer below
Explanation:
a) From the table, the glucose level of person 1 (5.4) was less than the glucose level of person 2 (5.6) after 12 hours of fasting. The glucose level of person 1 falls within the normal fasting blood sugar range (3.9 to 5.6 mmol/L) while that of person 2 was borderline higher than normal.
b) Also from the table, the glucose level of person 3 (12.1) was greater than that of person 1 (6.4) when the glucose levels were measured 2 hours after drinking 75 g glucose. Normal after-meal sugar level ranges between 6 and 10.9 mmol/L. Hence, person 3 appears to be diabetic while person 1 seems normal.
c) The hormone that person 3 cannot produce is insulin.
Insulin helps lower blood sugar levels when necessary by signalling the liver to convert the excess sugar to glycogen which is then stored in the body. When the blood sugar falls below the normal range, another enzyme, glucagon, signals the liver to convert the glycogen back to sugar to compensate for the decrease.

Answer:
Amino acid generated from tyrosines and tryptophan (end in '-ine') and includes adrenaline and norepinephrine. The (produced by the adrenal medulla). Thyroxine (production from the thyroid gland) and melatonin are also included in the amino acid hormones (produced by the pineal gland).
Explanation:
The main control over hormone production and release is negative feedback. The stimulation causes the release of a chemical in negative feedback systems; once it reaches a specific level, the substance sends a signal stopping further discharge.
This ensures a narrow range of the levels of hormones in the blood.
For example, blood glucose is controlled via negative feedback to secrete insulin and glucagons.
Which of the following adaptations enables deciduous trees to produce more food?
a.
broad leaves
b.
thick bark
c.
leaf loss
d.
color change
The presence of broad leaves, which is present in Option A, enables deciduous trees to produce more food. Broad leaves have the benefit of increasing the photosynthetic rate, resulting in more food production.
What is the role of the leaves?Leaves are of many types, such as the neddle-shaped leaf and flat leaves, and all these leaves are adapted to different climatic conditions. The plants that are present in the tropical area have comparatively flat leaves compared to those that are present in the cold areas in order to control transpiration and heat.
Leafy plants that are green in color have chloroplasts and chlorophyll pigments that help in the photosynthesis process. Because the photosynthesis process produces food, if the leaf is green, it has more chloroplasts and thus produces more food.
Hence, The presence of broad leaves, which is present in Option A, enables deciduous trees to produce more food.

A metric that measures the decline in population sizes, shrinkage of species, and geographic range is ________.
Answer: Living Planet Index
Explanation:
The Living Planet Index is a survey measure of global biodiversity status based on the population abundance of vertebrate species in terrestrial, freshwater and marine habitats. We have to consider that a population is defined as a species within a geographical area. It is used as a source of information to identify threats at the population level for each species on Planet Earth.
With this analysis, an overall decline of about 60 percent in population size has been seen between 1970 and 2014. The decline in species populations is particularly greatest in the tropics, with South America and Central America suffering the most dramatic decline. The numbers of freshwater species have also declined dramatically. However, measuring biodiversity (all the varieties of life that can be found on Earth and the relationships between them) is complex, so the index should consider indicators to measure changes in species distribution, extinction risk and changes in community composition.
The goal of the Living Planet Index is to achieve and promote global conservation of animals and their habitats.
The rapid diversification of species seen in the fossil record followed by long periods of stasis is part of the ________ model of evolution.
Answer:
punctuated equilibrium
Explanation:
According to the punctuated equilibrium model of evolution, the process of evolution involves a sudden spontaneous burst in the diversity of species (speciation).
This period is now followed by a long period in which the there is no change in the species. This period is known as the period of stasis or equilibrium.
Hence, the rapid diversification of species seen in the fossil record followed by long periods of stasis is typical of the punctuated equilibrium model of evolution.

A lending library has a fixed charge for the first three days and an additional charge for each day thereafter. Saritha paid ₹27 for a book kept for seven days, while Susy paid ₹21 for the book she kept for five days. Find the fixed charge and the charge for each extra day.
Answer:
See the attachment.
Hope u understand
In the given question, 5₹ is the fixed charge and 3₹ is the charge for each extra day.
A fixed charge is a fee or cost that remains constant and does not vary with changes in usage or consumption.
Let the fixed charge for the first three days be x and the charge for each extra day be y.
From the given information, we can set up two equations:
For Saritha: [tex]\rm 3x + 4y = 27 -----(equation 1)[/tex]
For Susy: [tex]\rm 3x + 2y = 21 -----(equation 2)[/tex]
We can solve for x and y by using elimination or substitution:
Using elimination, we can multiply the second equation by 2 and subtract it from the first equation:
[tex]\rm 3x + 4y = 27[/tex]
[tex]\rm - (6x + 4y = 42)[/tex]
Solving above equations, we get:
[tex]\rm -3x = -15[/tex]
[tex]\rm x = 5[/tex]
Substituting x = 5 into one of the equations, we can solve for y:
[tex]\rm 3(5) + 4y = 27[/tex]
[tex]\rm 15 + 4y = 27[/tex]
[tex]\rm 4y = 12[/tex]
[tex]\rm y = 3[/tex]
Therefore, the fixed charge is ₹5 and the charge for each extra day is ₹3.

does the gut flora affect digestion?
Answer:
Yes.
Explanation:
Our bodies need different organs to regulate our bodily functions, and the gut is no different. The gut flora helps us digest and break down the food we eat, along with producing various enzymes that help to break down carbohydrates. Also, after the carbohydrates are broken down, they can pass through the gut wall into the blood (just a little fun fact). The gut also helps to benefit our immune system. One last bit of information is that an imbalance of bacteria and microbes in our bodies may lead to weight gain, high blood sugar, high cholesterol, and many other terrible issues.

how would hemoglobin content differ in a person living in philadelphia compared to someone living in denver
Answer:
The correct answer is - the difference in altitudes.
Explanation:
The hemoglobin in the person of Denver who lives at a higher altitude than the person who lives in Philadelphia will be much higher. This is due to the fact that at higher elevation or altitude atmospheric pressure decreases that causes hemoglobin to stick to the RBCs and that results in less oxygen level in the body.
To compensate for this low level of oxygen levels hemoglobin content need to be higher in people living at a higher elevation.

How does reproductive isolation cause speciation?
A. It flows interbreeding.
B. It stops adaptive radiation.
C. It reduces gene flow.
D. It prevents divergence.
Answer:
C. It’s reduces gene flow.
Explanation:
Reproductive isolation cause speciation as it reduces gene flow. Therefore, the correct option is C.
Mechanisms that prevent or restrict the exchange of genetic material (gene flow) between populations are called reproductive isolation. When reproductive isolation occurs, populations become genetically isolated from each other, resulting in different evolutionary paths. This may eventually lead to the speciation or evolution of new species. Reproductive isolation limits the exchange of genetic variation between populations by limiting gene flow. This means that genetic changes, such as mutations or genetic drift, that occur in one population do not affect other populations in the same way.
Therefore, the correct option is C.

A student combined equal amounts of two solutions. One solution had a pH of 2 and the other had a pH of 12. Which would most likely be the resulting pH?
Answer:
This question lacks options, the options are:
A. 1
B. 3
C. 6
D. 11
The answer is C. 6
Explanation:
pH of a solution refers to the concentration of hydrogen ions in that solution. A scale is used to measure pH of a solution.
* A pH value less than (<) 7 is said to be ACIDIC. The lesser the number, the more acidic
* A pH value of exactly 7 is said to be NEUTRAL
* A pH value above (>) 7 is said to be BASIC OR ALKALINE. The higher the number, the more alkaline.
According to this question, two solutions of equal volume with pH values of 2 and 12 respectively were combined. Based on the explanation of pH scale, the solution with pH 2 is said to be very ACIDIC while the solution with pH 12 is said to be very ALKALINE.
Hence, if this two solutions are combined, a neutralization will occur which will result to a solution with close to neutral pH (7). In the above options, 6 is the closest pH value to NEUTRAL and hence, the most likely pH of the resulting solution.

Answer:
The correct option is ( have a respiratory system with spiracles connecting to tracheae).
Explanation:
The class INSECTA are under the phylum arthropoda which is the largest phylum in the animal kingdom. The insects are mainly land animals, they are widespread and adapted to all types of environment. They are also the only invertebrates that can fly. Examples of insects include: ants, butterflies, beetles, aphids and grasshoppers.
An insect has a well-defined head, thorax and an abdomen. The head had six segments and bears a pair of jointed antennae, compound eyes, simple eyes and mouthparts. The thorax had three segments, each bearing a pair of jointed walking legs. The abdomen has eleven segments and may have sensory and reproductive structures.
An insect carries out gaseous exchange by means of a network of open air tubes or TRACHEAE inside it's body. These tubes have openings called SPIRACLES to the exterior. Therefore the insects have an respiratory system with spiracles connecting to tracheae.
