Answer:
evolution of human works
Explanation:
The cell theory states that all living forms are composed of cells. These cells are the basic structural units of all organisms and they evolved from pre-existing cells present in primitive living forms. From a biological point of view, the evolution of cells is similar to the evolution of human works, which were during the beginning of human civilization less specialized than in modern times. Likewise, somatic cells present in evolutionary recent multicellular organisms are capable of carrying out more complex functions than primitive cells present in unicellular organisms.

Structure: cellulose and chitin
B) Energy: cellulose and chitin
Structure: glycogen and starch
C) Energy: chitin and glycogen
Structure: cellulose and starch
D) Energy: cellulose and starch
Structure: chitin and glycogen
The answer is option A
Explanation:
Carbohydrates are biological molecules in living systems. Polysaccharides are a type of carbohydrate molecules, which are polymers made up of monomers called monosaccharides. Monosaccharides such as glucose, fructose etc. are joined together by glycosidic bonds to form this polysaccharides. However, polysaccharides found in nature are classified based on their function in their found organisms.
1) Energy: Glycogen and starch are the two carbohydrate polymers that function in this aspect. They are both made up of long chains of glucose unit linked by α glycosidic bonds. Glycogen stores energy in the animal cells while starch stores energy in plant cells.
2) Structure: Cellulose and Chitin are the two carbohydrate polymers involved in this function. Cellulose is made up of glucose monomer linked together by β glycosidic bonds. It is the major structural component found in the cell wall of plant cells. Chitin is also a polymer of N-acetyl glucosamine and the major structural component of the cell wall of oorganisms like fungi.

When a cell undergoes meiosis, one diploid cell ends up dividing into(1 point) two haploid cells. two diploid cells. four haploid cells. four diploid cells.
Answer - two haploid cells
Hope it helps.
When a cell undergoes meiosis, one diploid cell ends up dividing into two haploid cells. Therefore, option A is correct.
What is meiosis ?Meiosis is a special type of cell division in which reduction of cell occurs, Therefore, it is also called as reduction division because it reduces the number of chromosomes to half the normal number.
When fusion of sperm and egg occurs, baby will have the correct number. When a cell undergoes meiosis, one diploid cell ends up dividing into two haploid cells. These cells are our sex cells, sperm in males, eggs in females.
The germ cells undergo the process of meiosis to produce haploid cells that are the sperm and the egg. The development of a new organism is then initiated by the mixing of these gametes at fertilization.
Thus, option A is correct.

The base composition of a double-stranded DNA molecule is 26% adenine. What percentage of this molecule is the base guanine? Give only the answer in numerical form so that Moodle will grade your answer correctly. Do not write "%".
Answer:
26
Explanation:
According to Chargaff's rule, a typical DNA molecule must have an equal ratio of both purine and pyrimidine bases. Purine is made up of Adenine and Guanine bases while pyrimidine is made up of Thymine and Cytosine bases.
Hence, if the amount of Adenine in DNA is 26%, the amount of Guanine would also be 26%. This would leave the remaining 48% of the DNA as Thymine and Cytosine to be shared in an equal proportion of 24% each.
In summary:
If Adenine = 26, Guanine would also be = 26
Adenine + Guanine = 52%
Thymine + Cytosine = 48%

Can anyone give a paragraph answer to what global footprint means! Thank you.
Answer:
The ecological footprint is a method promoted by the Global Footprint Network to measure human demand on natural capital, i.e. the quantity of nature it takes to support people or an economy.[2][3][4] It tracks this demand through an ecological accounting system. The accounts contrast the biologically productive area people use for their consumption to the biologically productive area available within a region or the world (biocapacity, the productive area that can regenerate what people demand from nature). In short, it is a measure of human impact on the environment.
Footprint and biocapacity can be compared at the individual, regional, national or global scale. Both footprint and biocapacity change every year with number of people, per person consumption, efficiency of production, and productivity of ecosystems. At a global scale, footprint assessments show how big humanity's demand is compared to what Earth can renew. Global Footprint Network estimates that, as of 2014, humanity has been using natural capital 1.7 times as fast as Earth can renew it, which they describe as meaning humanity's ecological footprint corresponds to 1.7 planet Earths.[1][5]
Ecological footprint analysis is widely used around the world in support of sustainability assessments.[6] It enables people to measure and manage the use of resources throughout the economy and explore the sustainability of individual lifestyles, goods and services, organizations, industry sectors, neighborhoods, cities, regions and nations.[2]

Which of the following best describes the circled part of the
statement?
7x + 9= 40
Answer:
4(3/7)
Explanation:
7x+9=40
7x=40-9
x=31/7
x=4(3/7)....
The circled part of the statement, "7x + 9," is the algebraic expression on the left side of the equation. This expression represents the sum of the product of 7 and the variable x and the value 9.
What is a mathematical expression?The circled part of the statement, "7x + 9," represents the mathematical expression for the left side of the equation. It is composed of two terms: "7x" and "9." The term "7x" is a product of a coefficient, 7, and a variable, x. This means that the value of "7x" changes depending on the value of x. The term "9" is a constant, which means that its value remains the same regardless of the value of x. Together, these two terms make up the left side of the equation and represent the value that we are trying to find by solving the equation.
The right side of the equation, "40," represents the value that we are trying to match the left side to by solving the equation. The equation is then solved by isolating the variable x, which is done by subtracting 9 from both sides of the equation, which results in 7x = 31, then dividing both sides by 7, which results in x = 4.5.

cycles?
A. water cycle
B. nitrogen cycle
C. cell cycle
D. Carbon cycle
Answer:
it is under a force of carbin cycle
D.CARBON CYCLE
Photosynthesis and cellular respiration are the driving forces behind carbon cycle.
What is carbon cycle?Photosynthesis and cellular respiration are the primary processes responsible for driving the carbon cycle, which is the movement of carbon through the Earth's atmosphere, oceans, and land.
Photosynthesis is the process by which plants, algae, and some bacteria convert carbon dioxide and water into glucose and oxygen using energy from sunlight. This process removes carbon dioxide from the atmosphere and stores it in the form of glucose, which is used by plants for growth and energy.
Cellular respiration is the process by which cells convert glucose and oxygen into energy, releasing carbon dioxide and water as waste products. This process occurs in all living organisms and is the reverse of photosynthesis.
The carbon cycle is also influenced by other processes such as the decomposition of organic matter, the burning of fossil fuels, and the release of carbon dioxide from volcanoes.

recently went to the doctor and it was determined that her kidneys are retaining sodium
causing an increase in blood volume. Use the information provided about this patient to
select the correct blood flow you would expect the patient to have and the correct effect
of that blood flow.
a. High Blood Pressure. Increased Blood Flow
6. High Blood Pressure. Decreased Blood Flow
C Low Blood Pressure increased Blood Flow
Lou Blood Pressure Decreased Blood Flow
Answer:
b. High Blood Pressure. Decreased Blood Flow
Explanation:
As per the details, patients's kidney is retaining more sodium causing increase in blood volume which will result into high blood pressure and decrease in blood flow.
This is because excessive salt in the body causes high blood pressure (hypertension) that results into stiff and narrow blood vessels and decreases blood flow to other organs. To overcome the supply of less blood to the organs, the heart pump blood with more intensity that further increases blood pressure.
Hence, the correct option is "b".
A 22-year-old woman engaging in a political protest goes on a hunger strike on a prominent corner in a city park. She refuses all offers of food except for water through the first 2 weeks. Under these conditions there is a decreased reliance on which of the following pathways for fuel?a. β-oxidationb. Lipolysisc. Ketogenesisd. Gluconeogenesis
Answer:
β-oxidation and gluconeogenesis
Explanation:
This 22-year-old woman, by not eating her food for a long time, entered a period of prolonged fasting.
Which there are no glycogen reserves, since they were depleted and neither were glucose assimilations by the cells because the person only ingested water.
Prolonged fasting is extremely dangerous because fatty tissues are degraded resulting in ketone bodies that are considered toxic and cross the blood-brain barrier.
Once the fat tissue reserve is completely finished, the body will enter into proteolysis of the body's own structural proteins in order to obtain energy, this is how the phenomenon of abrupt consumption of muscle tissue occurs.
