In order for the growth rate to remain constant what must happen to the birth rate?

1 answer:

5 0

<span>In order for the growth rate to remain constant, the birth rate must equal the death rate. This is the number of the population being born and the number of people dying. A birth replaces a death and vice versa, so if the birth rate and the death rate are the same, there are the same number of organisms total.</span>

If a system requires 150 J of input work and produces 123 J of output work, what's its efficiency?

tamaranim1 [39]

The efficiency of work is a dimensionless value, and is equivalent to the ratio of the actual work output to the theoretical work requirement. This can be calculated using the equation:

Efficiency = (actual work) / (work requirement) = 123/150 = 0.82

The higher the efficiency, the better performance is given by the system. In reality, efficiency is always lower than 1 which is the ideal value.

Check out this potato plant. We eat lots of potatoes. They are considered to be(1) a vegetable and (2) starchy. Starches are mad

kakasveta [241]

Answer:

The two main component of starch are amylose and amylopectin.

Explanation:

Carbohydrates are the important biomolecules of the living organisms. They provide structural and functional support of the living organisms. Carbohydrates are important in both plants and animals.

The starch provide important function in plants. The starch is polymers of made of glucose linked through the glycosidic bond. Amylose is the linear structure and amylopectin includes the branched chain and interaction in the structure of the strach.

Thus, the correct answer is amylose and amylopectin.

You start out with a cell suspension of 5e6 cells in a 10ml. you want to seed a new flask with half a million cells. how many mi

Free_Kalibri [48]

5e6 cells in 10mL means we have 5 million cells in this volume.

We can figure out this by cross-multiplication:
5.000.000 cells ==> 10 mL
500.000 cells ==> x mL
so 500.000 x $\frac{10}{5000000}$ = 1 mL.

So you take 1 milliliter of your initial flask and transfer it to the new one.

Mnenie [13.5K]

Answer:

The correct option is A. Theories that are related to the evolution of humans from apes will change.

Explanation:

The research from Dr. Katherine will change the theory of evolution of humans from apes because according to the theory of evolution changes in the genetic sequence of apes caused the formation of humans. But Dr. Katherine Pollard's research says that no deletion or addition of genes took place rather the genome of humans and apes is same with certain switches controlling the genome.
