Two hawk species are present in the same ecosystem. Hawk A feeds on mice and squirrels, both of which feed on seeds and nuts. The small population of Hawk species B eats snakes that feed on mice and squirrels. Which describes why Hawk B is the keystone species in this scenario?

Answers

Answer 1

Answer:

Hawk B species help other populations survive by keeping snake predation low.

Study the following statements, which compare the method of fermentation preferred by yeasts to they type of fermentation that may occur in human muscle cells. i. Yeasts produce CO2 during fermentation, but human muscle cells do not. ii. Different metabolic end products result from the two types of fermentation. iii. Yeasts produce more ATP per glucose in their fermentation than do human muscle cells. Choose the correct answer from below.

Answers

Answer:

Only one of the three statement is true; and that is,

(ii.) Different metabolic end products result from the two types of fermentation

Explanation:

Fermentation is the process by which organic molecules such as glucose are broken down into smaller molecules to extract energy as ATP in the absence of oxygen.

Fermentation is carried out by many organisms including man.

In man, fermentation occurs in very active skeletal muscles such as in an athlete running. It involves the reduction of pyruvate produced from the glycolytic pathway to lactate in the muscles. The net yield of ATP from glucose breakdown to produce lactate is 2 ATP molecules.

In microorganisms such as yeast, the fermentation product of py ruvate derived from glycolysis is ethanol and carbon dioxide, CO₂. The net ATP yield in fermentation of glucose in yeast cells is also 2 ATP molecules.

From the options provided in the questions, the correct option is:

Only one of the three statement is true and that is that, ii. Different metabolic end products result from the two types of fermentation.

None of the above

millions of years

Answers

Answer:

we must look at billions of years

When considering the entire period of time during which life on Earth has been evolving, we must look at: D. billions of years.

Evolution can be defined as a process of gradual change in the characteristics of various species of living organism over several generations.

Basically, these characteristics refer to gene expressions that are typically transferred from parent organisms to their offspring or successive generations.

The earliest life forms known to humans existed about 3.7 billion years ago and they are microscopic organisms (microbes) whose fossils were found on rocks.

In conclusion, when you are considering the entire period of time during which life on Earth has been evolving, you must look at billions of years.

In how many revolutions can a bicycle
wheel of diameter 4.9 m cover a dis-
tance of 46.2 km?​

Answers

Answer: :Total distance to be travelled = 4.4 km

= 4400 m

Diameter of wheel = 70 cm = 0.7 m

Radius of wheel= 0.7 / 2 m

Circumference of wheel = 2 * pi *r

= 2* 22*0.7 / 7* 2

= 22*0.1

= 2.2 m

No. Of revolutions = Total distance / Circumference of wheel

= 4400 / 2.2

= 2000

Cells are the basic building blocks of all living things.

They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions.

[tex]\sf\huge\underline\purple{Cell:-}[/tex]

Definition:-

“A cell is defined as the smallest, basic unit of life that is responsible for all of life’s processes.”

[tex]\rightarrow[/tex] Cells are the structural, functional, and biological units of all living beings. A cell can replicate itself independently. Hence, they are known as the building blocks of life.

[tex]\rightarrow[/tex]Each cell contains a fluid called the cytoplasm, which is enclosed by a membrane. Also present in the cytoplasm are several biomolecules like proteins, nucleic acids and lipids.

[tex]\sf\large\underline\purple{Functions:-}[/tex]

Following are the various essential functions of cells:

Cells provide structure and support to the body of an organism.The cell interior is organised into different individual organelles surrounded by a separate membrane.The nucleus (major organelle) holds genetic information necessary for reproduction and cell growth.Every cell has one nucleus and membrane-bound organelles in the cytoplasm.Mitochondria, a double membrane-bound organelle is mainly responsible for the energy transactions vital for the survival of the cell.Lysosomes digest unwanted materials in the cell.

In budding process, bud is simply an outgrowth of cells at one particular site.

Amoeba:
