Describe the structure and function of the skin
The skin is the largest organ of the human body. It has three layers: epidermis, dermis, and hypodermis.
The epidermis is the outermost layer. It is composed of keratinocytes, a type of epithelial cell that produces keratin. The compact nature of the epithelial cells of the epidermis makes the skin waterproof. Melanocytes are also found in this layer and produce melanin, or skin pigment. The epidermis function as protection against UV rays.
The dermis is the inner thicker layer that is mostly composed of connective tissue and connected to the epidermis by collagen fibers. The structures found in this layer are the hair follicle, hair root, sebaceous gland, and sweat gland. The dermis function is to excrete excess oils and waste out of the body through the production of sweat and production of vitamin D with specialized cells found in this skin layer.
The hypodermis is the innermost layer that is composed of adipose tissue. It functions as a cushion between the muscles and the skin.
Since both the liver and skeletal muscle can store glucose as glycogen, both organs can break down the glycogen into free glucose to release into the blood.
a. true
b. false
Since glucose is required for muscle contractions, a proper glucose metabolism is crucial for optimal health.
What different role of glucose in liver and skeletal muscle?When the muscle contracts, the GLUT4 glucose transporter moves glucose from intracellular storage depots to the plasma membrane and T-tubules, allowing it to enter the muscle cell.
A little quantity of glucose is kept in the brain, but the majority of it is kept as glycogen in the liver and skeletal muscles.
Exercise-induced muscle contraction boosts glucose absorption in skeletal muscle in addition to insulin stimulation. The facilitative GLUT4 is redistributed from intracellular storage vesicles in response to both stimuli.
Therefore, it is false that both the liver and skeletal muscle can store glucose as glycogen.

The density of gold is 19, 320 kg/m³ and the density of
mercury is 13, 500 kg/m³. If a cube of gold that measures
0.100 m on each side is placed in a tank of mercury and
weighed while under the surface, what is the apparent weight
of the cube?
The apparent weight of the submerged gold is 57N.
What is apparent weight?According to physics, an object's perceived weight is a characteristic that describes how heavy it is. When the force of gravity acting on an object is not counterbalanced by a force of equal but opposite normality, the apparent weight of the object will differ from the actual weight of the thing.The weight of a passenger on an elevator is one illustration. When the elevator starts to rise, the object starts to apply downward force. If a scale were used, it would be clear that the downward force is making the object heavier and changing its apparent weight.So, the weight of mercury is 13500kg/m³ × (0.1m)³ = 13.5kg = 132.3N.
The initial weight of gold is 19320kg/m³ × (0.1m)³ = 19.35kg = 189.3N.
Then, the apparent weight of submerged gold is:189.3N - 132.3N = 57NTherefore, the apparent weight of the submerged gold is 57N.

The 3 Basic Components of the Cell Theory were then complete:
The 3 postulates of the Cell Theory are:
-Every living being is composed of cells, therefore they are the minimal functional unit of life, in their different levels of structural complexity. One single
cell is enough to make up an organism, but also multiple cells can organize in colonies or in a single organism, diversifying their functions and having a margin of independence quite elevated as a whole.
-All of the vital functions of living organisms have a place inside the cell, through biochemical processes and are controlled by substances that the cell secrete. Each cell operates as a unique open system, that exchanges matter, and energy with its environment in a controlled way. Moreover, in each cell of an organism are present the same vital functions that are in the organism itself, that is birth, growth, reproduction, and death.
-Every existing cell comes from a previous cell, by cell division, or by formation from stem cells.

In a respiration experiment we are measuring the rate alcoholic Fermentation in yeast by measuring the amount of CO2 produced Please assist with following questions
Answer and explanation:
1. sources of error- in the experiment, the amount of carbon dioxide released by east is monitored, a source of error could be the carbon dioxide present in the atmosphere which would interfere with the results.
2. baking recipes add sugars and molasses to provide carbohydrates for the yeast. this acts as a source of energy for the fermentation process.
3. the respiration of yeast could be monitored by measured the amount of sugar used or by measuring the amount of ethanol produced in the respiration process
4. high concentrations of sugar my inhibit yeast activity most likely because of the high osmotic concentration which prevents yeast from getting enough water for growth. as the osmotic concentration increases a yeast cell will reach a pont where water moves out of the cell.
A patient with and O blood type can receive a transfusion from a donor with blood type ____ only.a) ABb) Oc) AB, A, or Od) AB, A, B, or Oe) AB, A, or B
Blood types are determined by the proteins present on the surface of the red blood cells.
• In blood type A, red cells have A antigens and there are anti-B antibodies in the plasma.
,• Blood type B has B antigens and anti-A anitbodies
,• Blood type AB has A and B antigens and no antibodies
,• Blood type O, has ,no antigens ,and ,both anti-A and anti-B antibodies.
Is important not to pair antigens and antibodies, as the antibodies of the recipient will attack the antigens.
For example, if a person with O blood type receives AB blood, the patient's anti-A and anti-B antibodies would attack the donor's blood because the red cells have A and B antigens.
This means that a person with O blood type can only receive blood type O because those red cells don't have any antigens on their surface (option b).

Which of these is not a function of some membrane proteins A keeping polar molecules out of a cell B receiving messages from other cells C recognizing other types of cells D Catalyzing chemical reactions in the cell
Membrane proteins are those structures that are joint to the membrane of the cell, which allows it to have communication between its inside and its outside, but they have a limited size, and because of that, they keep great polar molecules outside the cell, also receive messages from neighboring cells, and recognize other types of cells, but they are not involved in the catalyzation of chemical reactions in the cells, since their function is mainly allow the movement of molecules from inside to outside or vice versa, and, as we've seen, also the communication between other cells.
So the answer to this question is D. Catalyzing chemical reactions in the cell, what they don't do.
In developing countries with high population rates, at which trophic level do people generally thrive?
In developing countries with high population rates, people generally thrive at a trophic level of 2.2.
Trophic levels are the positions that feed in a food chain or web. The population size diminishes as you move up the trophic levels of an environment.
Numerous consumers consume food at various trophic levels. When people eat plants like vegetables, they are the primary consumers. When they eat cows, they are incidental consumers. When they eat fillets, they are secondary consumers.
Higher trophic levels typically have fewer creatures since there is less energy there. At higher trophic levels, organisms are often greater in size, but because there are fewer of them, there is less biomass produced. The total mass of all trophic-level creatures is known as biomass.

What are transposable elements and what is their significance?
Transposable elements are DNA sequences, genes. With the capacity to move inside the genome, that is to say, they can change their position in the genome by themselves. Due to this ability to change position, they have been widely studied, although many times insert themselves on inactive genomic regions, they have contributed to genetic diversity and generating polymorphisms, which in turn have an impact on the evolution. Also in a low percentage of cases can generate genetic illnesses in early embryonal states, like some ehemofilias or leukemias.

DIFFRENCE BETWEEN PERMANENT TISSUE AND MERISMETIC TISSUE
Thankuu~
Answer: Meristimetic tissue continues to divide and help the growth of a plant. Permanent tissue consists of plant cells that no longer divide.
Explanation: Trust me.
Meristematic tissue
The tissues (group of cells) which undergoes repeated cell division. At the tip of the plant, there is apical meristem. Those tissue helps the plant to grow longer. If the apical meristem is cuts accidentally, then the plant no longer grow and dies.
Permanent tissue
The tissues (group of cells) which does not undergo repeated cell division. The middle portion of the plant cells is permanent tissue.
Overall the plant growth depends on the apical meristematic cells.

The dominant allele is T (it is always represented with the uppercase letter) and it codes for tall. This type of allele masks the effect of another allele.
The recessive allele t (it is represented with a lowercase letter) codes for short. This type off allele has its effect masked by a dominant allele.
When we look at the Punnett square we can see the offspring possible combinations:
TT: 25%
Tt: 50%
tt: 25%
The TT combination results in a tall offspring as the T allele is dominant.
The Tt combination results in tall offspring as T allele is dominant against t allele.
The tt combination results in short as both alleles ar ressesive and code for short.
As a result a 75% of the offspring will be tall and 25% will be short.
