Answer:

1/2

Explanation:

You have a 1/2 chance of having a boy and a 1/2 chance of having a girl.

Unless the question specifies whether or not there is a mutation present with the male parent, it is safe to assume there is a 50/50 shot of having a boy or girl.

inhibition is a mechanism of succession in which Group of answer choices the arrival of one species at a site affects the subseq
Stolb23 [73]

Answer:

option B: one species decreases the probability that a second species will become established

Explanation:

Inhibition as a mechanism of succession occurs when some early species which could also include pioneer species make the site less suitable for the development of other species and do not allow them to become established and grow. When eventually these early species die, other species that were hindered will subsequently grow and become established gradually giving rise to a climax community.

You've found an unfamiliar animal. How would you determine if it was a vertebrate or not without dissecting it?​
Brrunno [24]

If an animal is having a well developed skeleton system, a backbone then it belongs to vertebrate. Also, size is an important factor to identify vertebrate and invertebrate.

Explanation:

Vertebrates have a well developed skeleton system and backbone. Their skeleton system is made up of bones and cartilage. While, invertebrates don't have any backbone.

Due to lack of backbone or skeleton system, invertebrates are small in size. As there is no proper mechanism to support large body so invertebrates are small in size and also they move very slowly. This is also a major difference in vertebrate and invertebrate.

Another important difference between vertebrate and invertebrate is that body of vertebrate is covered with some structure like hair, feathers, skin, scales or a combination of these.

These features help to distinguish vertebrate from invertebrate by observing them, no need to dissect.
