Answer:

False

Explanation:

The first living thing on planet earth was a single celled species commonly termed as prokaryotic. These simplest forms of species were made up of primordial chemicals which some how under specific environmental condition developed into proteins and RNAs thereby generating higher forms of life.

Alja [10]

Answer:

The correct answer will be option-A

Explanation:

The practice of marriage is practised in every culture which is associated with the union of the boy and a girl to which they are committed to spending a life-long relationship.

The studies on the preferences shown by the woman who has to get married have to look for the boys who are career-oriented which could provide a good earning to feed them and their family and fond of children to establish a family which will help develop the stronger relationship between them.

The girls ignored the attractiveness feature of their spouses as in a long term relationship attractiveness does not matter because of the feeling of love and strong bond between them.

Thus, option-A is the correct answer.

Question 1
noname [10]
1 - A ground level plant develops curling tendrils that wrap around other objects so it can "climb".

This is a species changing over time as it was originally a ground level plant but began to climb higher.

2 - Over many generations.

This is because diversity takes time and has to be integrated through generations; for instance, marriage. In a family, it becomes more diverse after the next generation as each generation is likely to marry someone of another ethnicity and allow the family tree to become more diverse.

3 - Mutate or Survive

It depends on what it means by mutate - develop a mutation to make it adaptable? If that's the case, then mutations within the DNA would be a result of adaptation and increase survival. Otherwise, survive is the obvious answer as adaption allows for species to move around and live longer.

Hope this helps!

gavmur [86]

According to the research, the correct option is uni-axial synovial joint. When considering the classification of joints based on the shape of the articulating bone ends, the knee functions as a type of synovial joint are called a <u>uni-axial synovial joint</u>.

<h3>What are uni-axial synovial joints?</h3>

They are synovial joints because they have cartilage and a joint capsule that allow flexion and extension movement, and it is because they move in a single plane or axis that they are considered monoaxial.

In this sense, they can be located in the humeroulnar joint located in the elbow, in the femorotibial or knee joint, allowing the rear sides of the leg to be moved away or closer, and finally in the joints that form between the phalanges of the fingers.

Therefore, we can conclude that according to the research, the correct option is uni-axial synovial joint. When considering the classification of joints based on the shape of the articulating bone ends, the knee functions as a type of synovial joint are called a <u>uni-axial synovial joint</u>.
