Answer:

C. a dog buries a bone in the backyard

Explanation:

A dog burying a bone in the backyard is not an observation in terms of scientific methods.

Observation is the process of acquiring data about a phenomenon under study.

Most times, senses are used in making observations. Our sense of taste, hearing, sight etc. comes handy when making observation.

Also, we can use some specialized equipment to make observations.

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.

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.

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.

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.

Explanation:

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

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.
