Biology
1 answer:
7nadin3 [17]3 years ago
5 0

Explanation:

In reference to evolution, homology can be described as the comparative similarities in the structures of organisms that make it more alike to one organism than the other organisms. It also shows the characteristics that might have evolved in an organism over time. Developmental homology are the similarities which arise between organisms due to similar embryological source.

Developmental studies can be made by researching the embryological developments of different organisms and looking for similarities among them.

For example, studying the snake embryos showed that some of the embryos have hind limb buds in them which disappeared in the mature snake. This study made it clear that snakes evolved from organisms that had hind limbs. As the snakes do not need the limbs, so with time the species of snakes evolved and lost their hind limbs.

andre [41]

The correct answer is option C, For more kingdoms were introduced

Linnaeus  was the first to develop a system of classification of living things. He mainly grouped the living things into animal or plant kingdom, but later with the advent of microscope it became easy for the researchers to observe microscopic beings and thus three new kingdoms were proposed namely- fungi, protists (considered as simple organism) and monera (bacteria).  

Not only this with in a kingdoms comes several phylum, these phylums were also reorganized and recategorised based on the discovery of more categories and subcategories.

Middle adolescence is characterized by __________.A.feelings of invincibilityB.simple thinking processesC.increasing conflict wi
Alexxx [7]

Answer:

A) Feelings of invincibility

Explanation:

Adolescence refers to the period of human growth that occurs

between childhood and adulthood. Adolescence begins at around age

10 and ends around age 21. Adolescence can be broken into three

stages: early adolescence, middle adolescence, and late

adolescence. Each stage has its own characteristics. Let's take a

look at each stage in more detail below.

Middle adolescence is the second stage and occurs from ages 15 to

17. By this time, puberty has passed. Teens in this stage are

extremely concerned with how they look, and they think others are

concerned, too. They spend a large amount of time grooming,

exercising, and modifying their physical appearance.

Girls are especially preoccupied with their physical appearance and

being sexually attractive.

Relationships are often changing during middle adolescence. There

is also worry about sexual attractiveness. Middle adolescents

complain about their parents preventing them from becoming

independent, and they withdraw from them. They may try to assert

their independence by refusing to bathe, not cleaning their rooms,

and picking up annoying habits. There is an intense focus on peer

groups during middle adolescence, and teens in this stage tend to

confide in each other more than they do their parents.

As with early adolescence, teens in middle adolescence may feel

invincible. Risk-taking behaviors are significantly increased during

this stage. On the other hand, acting-out behaviors begin to

decrease, since teens in this stage have a better grasp on how to

use words as a means of expression.
