100 g of a mystery metal at 250 C is added to 400 mL of water at 15 C. The final temperature of the system is 15.9 C. What is the heat capacity
of the mystery metal?
(PLEASE HELP need the answer by 10/21/20
11:00pm)
Answer:
c = 0.064 j/g.°C
Explanation:
Given data:
Mass of metal = 100 g
Initial temperature of metal = 250°C
Volume of water = 400 mL
Initial temperature of water = 15°C
Final temperature = 15.9°C
Heat capacity of metal = ?
Solution:
First of all we will calculate the heat lost by metal into water.
ΔT= 15.9°C - 15°C
ΔT= 0.9 °C
q = mcΔT
q = 400 g× 4.184 j/g.°C × 0.9 °C
q = 1506.24 j
Specific heat capacity of meta;
ΔT = 15.9°C - 250°C
ΔT = -234.1 °C
q = mcΔT
-1506.24 j = 100 g× c × -234.1 °C
(negative sign with q value indicate heat is lost by metal)
-1506.24 j = -23410 g.°C × c
c = -1506.24 j /-23410 g.°C
c = 0.064 j/g.°C

Which step is the beginning of photosynthesis?
Answer:
light dependant reactions
Explanation:
Photosynthesis is carried out by green plants. The initial step of photosynthesis is the photolysis of water. This is a part of the light reaction.
What is photosynthesis?Photosynthesis is completed in two steps: the light-dependent reaction and the light-independent reaction. The sun is required for the light-dependent reaction. Two photosystems are involved in the light reaction. Light reaction starts from photolysis of water.
The reaction starts at photosystem II (PSII). At this site, the photolysis of water takes place. As a result, sunlight causes the water to break and electrons to be released. This electron moves to plastoquinone. During the electron movement, protons are pumped to the thylakoid lumen.
From the plastoquinone, an electron moves to the cytochrome complex and then to the PSI complex through plastocyanin. From the PSI complex, the electron moves to NADP reductase to form NADPH. All the protons present in the lumen move through the ATP synthase complex, and ATP is produced. The journey of electrons starts with the photolysis of water.
Hence, photosynthesis starts with the breakdown of water molecules.

Describe the relationship between photosynthesis and cellular respiration.
Answer:
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

What is the purpose of Mitosis? *
A. To produce an egg and a sperm cell.
B. To produce a new organism (like bacteria).
C. To produce a new cell (NOT a new organism).
D. To differentiate.
Answer:
C.
Explanation: Mitosis is a process where a single cell divides into two identical daughter cells (cell division). During mitosis one cell? divides once to form two identical cells. The major purpose of mitosis is for growth and to replace worn out cells.
Hope this helps! Have a nice day!
Answer:
C. to produce a new cell
Explanation:
Mitosis consists in replicating the genetic material of a mother cell in order to make two identical daughter cells; this is a diploid process. In order to make an egg or sperm cell and eventually a new organism, the correct process would be meiosis, since it combines the DNA between two cells and it is an haploid process.

3. Which of the following is a defining characteristic of a prokaryotic cell?
a. The method of cellular Respiration
b. The composition of the cell membrane
C. Absence of a membrane-bound nucleus
d. The method of movement
Answer:
C
Explanation:
Prokaryotic cells do not have any membrane-bound organelles, only eukaryotes do.
The prokaryotic cell is a simple primitive cell, unlike the complex eukaryotic cells. The absence of a membrane-bound nucleus is a characteristic of prokaryotes. Thus, option C is correct.
What is a prokaryotic cell?Prokaryotes have been the cells that have lived on earth for millions of years ago. They are made of single cells and hence are unicellular. Unlike the eukaryotic cell, they have simple mechanisms of living and reproduction.
They lack a centrally located defined nucleus that is not covered in any membrane and lies simply in the cytoplasmic material. Also, they lack organelles that make them different.
The genetic material is located in a concentrated form in a structure called the nucleoid that lacks a nuclear membrane.
Therefore, option C. the prokaryote lacks a membrane-bound nucleus.

5. Which of the following statements best describes the response of finches to drought on the Galapagos Islands?
O A During drought, individual finches saw that large, hard seeds were the only available food. To crack these harder seeds, individual finches grew their beaks
larger, resulting in an increased average beak depth
OB During drought, finches struggled to open harder seeds All the scraping and pecking wore down their beaks, resulting in a reduced average beak depth
OC. During drought, only finches with larger-than-average beaks were able to crack the hard seeds that were available. These finches survived while smaller-
beaked finches died, resulting in an increased average beak depth in the population
O D. During drought, finches with smaller beaks (and smaller bodies) had an advantage. With reduced food supplies, larger finches (with larger beaks) were
more likely to starve. The result was a decrease in average beak depth
Answer:
it is c got it right on the quiz
Explanation:D hope this helps
A. During drought, individual finches saw that large, hard seeds were the only available food. To crack these harder seeds, individual finches grew their beaks larger, resulting in an increased average beak depth
How large beak finches survive drough condition?During drought, finches with larger beaks survive because they were able to crack the hard seeds that were available in the drought situation while on the other hand, the smaller beaked finches died due to unavailability of food which result in an increased average beak length in the population.

How would you describe the difference in the motion of the sled from when the people first start pushing to when the sled is halfway down the hill?
The difference in the motion of the sled from when the people first start pushing to when the sled is halfway down the hill will be described as after starting off much more slowly, it picks up speed significantly by the bottom of the slope.
At the top of the hill, a sled has pushed itself. If we then apply a tiny push, the sled's initial speed will be 0, indicating that the sled's only starting energy is gravitational potential energy. Therefore, assuming there is no friction, the sled's greatest height will be equal to its initial brightness. So the slides will never make up for a bump that is higher than its starting point. The sled's highest point is equal to its initial height because of the rule of conservation of mechanical energy. The sled will never make it up if they restrict it if the friction is seated.
