enyata [817]

Answer:

mamals and birds

Explanation:

The Organs which perform same function and looks but they are different in their structure from each other are called as analogous organs.

Organs are the structures that made up of two or more tissues organized to carry out a particular function.

An organ or bone that appears in different animals with same function is called homologous structure.

Homologous organs have similar origin n basic structure but perform different functions in different organisms. Analogous organs are different in basic structure but perform same functions.

Different animals have bones that appear very similar in form or function and seem to be related.

Examples

The arm of a human, the wing of a bird or a bat, the leg of a dog and the flipper of a dolphin or whale are homologous structures. They are different and have a different purpose, but they are similar sharing common traits.

The forelimbs of all mammals have the same basic bone structure.The structures are similar because they evolved to do the same job.  For example, the wings of bats and birds.

Consider what you have learned about the role of genes, and in some cases their interaction with environmental factors, in human
Nadusha1986 [10]

Answer:

to adopt a healthy lifestyle in order to prevent and/or reduce the risk of developing complex diseases

Explanation:

Complex genetic diseases are diseases that have a genetic basis but often don't show a clear pattern of inheritance, i.e., the genes that encode for the trait of interest are localized in quantitative trait <em>loci </em>(QTL). In general, complex genetic diseases are multifactorial because both genetic and environmental factors play important roles in the development of this type of disease. Some well-known examples of multifactorial genetic diseases include, among others, heart diseases, diabetes, asthma, some type of cancers, etc. It is well known that healthy lifestyle habits such as maintaining a healthy weight, eating healthy foods, avoiding harmful substances, etc., can prevent complex genetic conditions from manifesting.
