The correct answer is true.

The density dependent factors are those factors, which is affect the size of the population.

The logistic growth curve shows a a lag phase, a log phase and a stationary phase. In the lag phase, the growth of the organism is minimal, here it prepare for the growth, in log phase, the population growth is exponential. As the resources in a particular area is limited and carrying capacity is also limited, after a certain population density, the growth become stationary, which means mortality becomes equal to the birth rate. As the logistic curve is affected by the density of the population, it would be density dependent.

P.S.- if the resources are not limited, the population continuous to grow exponentially, and would represent exponential growth curve.

Answer:

Option B

Explanation:

Question -

You just came back from class in which the topic was egocentrism in the preoperational stage. You have a 4-year-old and thought that you would see if what you learned was accurate. You are sitting directly across from her and ask her to look at the front and back cover of her favorite book. After she did this you asked her to describe "the part of the book I am looking at." What does she tell you?

a) how many pages there are in the book

b) what she sees

c) what you see

d) what the story is about

Solution

As per Piaget's theory of cognitive development, when a child is at the preoperational stage he/she is able to think only at symbolic level and cannot use his/her cognitive thinking.

He/she is unable to derive senses or meaning associated with symbols and also his/her communication is egocentric which means they cannot think from the perspective of other people.

Hence, option B is correct

What was Robert Brown looking at through a microscope when he found evidence of the 1827 scientific concept named in his honor?

Alexxx [7]

He was looking through a microscope at particles trapped in cavities inside pollen grains in water. The concept of Brownian motion is named after him. This is the random motion of particles suspended in a fluid, liquid or gas resulting from their collision with the fast-moving molecules. Here, the patterns of motion of the particles are typically alternations between random fluctuations in a particle's position inside a fluid sub-domain with a relocation to another sub-domain. Each relocation is followed by more fluctuations within the new closed volume.

dolphi86 [110]

Despite their seemingly simple anatomy and radial symmetry Sea urchins and sea star are a type of deuterostome, closely related to the chordates.

What are the characteristics of deuterostome?

Animals classified as deuterostomes share a common embryonic development.

The first opening during development known as the blastopore changes to the anus in deuterostomes while the mouth changes in protostomes.

They have a coelom, which forms as a result of enterocele (coelom from the digestive tract).

These creatures include the following,

- Chordata,

- Echinodermata,

- Hemichordata.

Hence the correct answer is Deuterostome.
