partially weathered parent material
Explanation:
From deep to superficial, the order of the strata of the epidermis is corneum - granulosum - lucidum - spinosum - basale. spinosum - granulosum - basale - lucidum - corneum. basale - granulosum - spinosum - lucidum - corneum. corneum - lucidum - granulosum - spinosum - basale. basale - spinosum - granulosum - lucidum - corneum.
Answer:
basale - spinosum - granulosum - lucidum - corneum.
Explanation:
The order of strata in the epidermis:
Basale: it is the deepest stratum. It has one layer of cells called keratinocytes, which are stem cells for the epidermis.Spinosum: The keratinocytes in this layer have spiny shapes. They synthesize cytokeratin and lipids. In this layer, we can also find macrophages.Granulosum: The keratinocytes of the previous layer ascend and synthesize keratohyalin, which is in granules. The keratohyalin helps to join keratin filaments. Also, the cells release the lipids synthesized in the previous layer, and they form a barrier that stops dehydration.Lucidum: it is only on thick skin, like the one in the sole of the feet. The keratinocytes in this layer have expelled the nucleus and now are dead cells. The keratinocytes have a flat shape and form a thin layer.Corneum: it is the most superficial layer. It is made of dead keratinocytes filled with keratin in their cytoplasm. It is a thick layer that suffers desquamation when new dead cells filled with keratin ascend from the previous layer.what are evidence that the himalayas mountain are still rising

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.
Consider a neuron in which the Cl- concentration inside of the cell is 15 mM and outside of the cell is 140 mM. Once the ions flow and reach an equilibrium, approximately what will be the concentration of Cl- inside of the cell
Answer:
The correct answer is - negative.
Explanation:
Cl- ion is more concentrated outside of the cell, as it is given 140 and therefore it will try to move to the inside of the given cell as inside ion concentration is low.
At last, the diffusive force will be get to equilibrium due to an electrostatic force pulling Cl- ions back out of the cell. At this equilibrium point, Cl- ions will moved towards to the the neuron and cause the membrane potential to be more negative.
The last common ancestor of all animals was probably a(n) The last common ancestor of all animals was probably a(n) algae. chytrid. yeast. protist. fungus.
Answer:
The correct answer is - protist.
Explanation:
Protist is a single-celled eukaryote that contains organelles. It is the last common ancestor of all animals as is consider as most primitive animal cells as it has no cell wall but contains the nucleus and other double-membrane organelles. The protists are the cell that distinguishes fungus, plant cells, and animal cells into these three different kingdoms.
Thus, the correct answer is - protist.
In the electron transport chain, which structure forms a channel in the inner membrane of the mitochondria and adds phosphate to ADP
Answer: ATP synthase
Explanation:
The ATP synthase complex is an enzyme located in the inner membrane of the mitochondrion that catalyzes the synthesis of ATP from ADP, a phosphate group and energy supplied by a proton (H+) flux. This ATP synthesis occurs during cellular respiration, which is a set of biochemical reactions by which certain organic compounds are completely degraded by oxidation to inorganic substances. This process provides usable energy to the cell in the form of ATP.
During cellular respiration, ATP synthesis is termed oxidative phosphorylation and the proton flux takes place between the intermembrane space and the mitochondrial matrix. ATP synthase produces ATP when protons flow through it. The proton flow creates a pH gradient and an electrochemical gradient. This proton gradient is used by ATP synthase to form ATP via oxidative phosphorylation. ATP synthase acts as an ion channel that "returns" protons to the mitochondrial matrix. During this return, the Gibbs free energy produced during the generation of the oxidized forms of electron transporters is released. This energy is utilized for ATP synthesis. It must then be considered that the electron transport chain and oxidative phosphorylation are coupled by the proton gradient.
What is a variegated leaf
Answer:
The term, "variegated" is applied to a flower or, more often, a leaf that has more than one color. Most often, it will be two-toned (that is, bi-colored). Often this will mean the foliage is blotched, striped, or bordered with a lighter color than that on the rest of it (or vice versa). The term is also applied more broadly to a whole plant that bears such leaves or blossoms. The corresponding noun for this definition is "variegation."
how is the structure of endoplasmic reticulum related to its function?
Answer:
The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.

Answer:
The correct answer is -
1. Lupus
2 Cardiovascular disease
3. Huntingtons disease
4. Cancer
5. Diabetes
Explanation:
Lupus is one of the autoimmune diseases that takes place when our bodywork against ourself and harm cells and skin. When an individual has poor or bad nutrition and generally experiences obesity this cardiovascular disease occurs.
Huntington's disease takes place due to changes in DNA in the brain and affects neurons of the brain. Cancer is uncontrollable cell growth that can be lethal. If an individual is not able to produce enough amount of insulin, that lowers the glucose from the blood, will lead to cell diabetes condition
There are sixty-one mRNA codons that specify an amino acid, but only forty-five tRNAs. This is best explained by the fact that
Answer:
See the answer below
Explanation:
The phenomenon is best explained by the fact that the genetic codes are degenerates. In other words, more than one codon can specify for the same amino acid being carried by the tRNA.
The base-pairing rule between the third nucleotide of a codon and that of the anticodon on the tRNAs loosens off. For example, GUU, GUC, and GUA all specify for the amino acid valine while GCU, GCC, and GCA all specify for alanine.

Select the correct answer from each drop-down menu. Study the graphs, and then complete the passage. An anomaly in global temperature is a deviation from what is normal or expected. The graph shows that global atmospheric co2 ___(increased exponentially. Remained constant. Increased slightly)in the twenty-first century, and global temperature also increased during the same time. Based on the timeline, these statistics suggest a correlation between climate change and ___(wind energy production. Use of electric cars. Industrial carbon emissions). If the current trend of increasing co2 levels continues, the greenhouse effect will continue to ___(warm the planet. Release gas into space. Destroy carbon dioxide) .
Answer:
Increased exponentially
Industrial carbon emission
Warm the planet
Explanation:
The rapid increase in global CO2 in the 21st century has raised concerns over the lingering effect of global climate change which could result due to the exponential increase in CO2 emission at this time. This rise in global atmospheric CO2 has been observed to have a positive relationship with the level of industrial carbon emission. The rise in emission of industrial carbon has been tipped to be responsible for the exponential rise in global atmospheric CO2. CO2 is a form of green house gas responsible for warming the planet.

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.

Which is the best definition of directional selection?
a process by which two species can no longer reproduce
a process by which one of the extreme variations of a trait is favored
a process by which individuals with either extreme of a trait are favored
a process by which average individuals in a population are favored
Answer:
B. a process by which one of the extreme variations of a trait is favored
Explanation:
The graph for this type of selection looks sort of like a camel's hump. With that being said, the phenotype of a population experiencing directional selection goes from one extreme to the other. Reference the evolution of the peppered moth during the Industrial Age as an example.
Sincerely hope this helps! God bless!A process by which one of the extreme variations of a trait is favored best describes the directional selection. Therefore, option (B) is correct.
What do you mean by directional selection?Directional selection is a negative natural selection mode in which an extreme phenotype is preferred over other phenotypes, causing the allele frequency to shift over time in that phenotype's favor.
Fossil evidence suggests that while the size of European black bears decreased during interglacial periods of the ice ages, it increased during each glacial period. This is an example of directional selection. A further illustration is the size of a population of finches' beaks.
The behavioral trait in question experiences a concentration of increasing alleles in the line selected in the upward direction and a concentration of decreasing alleles in the line selected in the downward direction.
