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.

Unlike endocrine glands, exocrine glands... A. Release secretions outside of the body B. Release hormones C. Do not usually have
Maru [420]

Unlike endocrine glands, exocrine gland RELEASE SECRETIONS OUTSIDE OF THE BODY.

There are two types of glands in the body, the endocrine and the exocrine glands. The endocrine glands are ductless glands and their secretions are normally released directly into the blood stream. The exocrine glands on the other hand have ducts, through which their secretions are release outside the body. An example of this is the sweat gland.

Consider the following three populations of birds. Assume HW equilibrium. With these birds red coloring is recessive, while brow
bixtya [17]

Answer:

Red allele frequency will be highest in population II

Population III can undergo bottleneck effect

The frequency of the brown allele will  least likely be altered in the population I

Explanation:

Population I -

Total population - 670

Brown birds - 603

Red birds - 67

Population II

Total population - 100

Brown birds - 90

Red birds - 10

Population III

Total population - 30

Brown birds - 27

Red birds - 3

Frequency of red birds in population I

\frac{67}{670} = 0.1

Frequency of red birds in population II

\frac{10}{90} = 0.11

Frequency of red birds in population III

\frac{3}{30} = 0.1

Red allele frequency will be highest in population II and it will be equal to \sqrt{0.11} = 0.33 as compared to 0.31 in case of population I and III

Population III can undergo bottleneck effect because of smaller population size

The frequency of the brown allele will  least likely be altered in the population that has highest  brown individual , i.e population I
