Answer:

The correct answer is - fibrous, cartilaginous.

Explanation:

In the body, there are joints named after the type of tissue attached to them and these joints are:

1. fibrous joints - these are connected with dense connected tissues and called immovable or fixed joints.

2.cartilaginous joints - these are joined by cartilage tissue. These joints are also not able to move freely.

3. synovial joints are known as movable joints and can move freely. These are present in a fluid-filled capsule for better movement.

What is happening in this image? How does it help illustrate the concept of natural selection?
GarryVolchara [31]

Answer:

In this image the bird is eating an insect off of a leaf that is easy to see whereas the insect on the other leaf is camouflaged and still alive. This helps illustrate the concept of natural selection because the camouflage insect is able to survive longer and therefore reproduce more.

ancestors of giraffes with shorter necks could not reach branches high up in trees for food. this led to selection for longer-ne
hichkok12 [17]

With shorter necks, giraffe ancestors could not reach food-containing branches on tall trees. This resulted in the directional selection of giraffes with longer necks.

 

<h3>Why is choosing a direction necessary? </h3>

It nearly appears obvious that the giraffe's long neck developed as a result of a lack of food in the lower branches of trees. The giraffe has a significant advantage because it is taller than any other mammal and can feed where few others can. 

When compared to modern giraffes, the giraffe's ancient predecessors had a shorter neck. The plants that were lying at a higher level were inaccessible to them. Giraffe phenotypes have changed in various ways, and now have long necks to reach vegetation that is higher up. The extreme form is chosen above other features in directional selection. It was decided to choose the long-necked giraffe over the short-necked.

A gene with the sequence ATTCATTCA underwent duplication after a few generations. Which sequence represents this gene after the
Ratling [72]

Answer:

The sequence would be <u>ATTCATTCA</u>.

Explanation:

Usually, when a sequence is duplicated, one of them becomes a non-coding. It's just like a computer. There can only be one specific file, or else a duplicated one will just replace the existing one, if you allow the file to do so. Same with DNA. This is why most of our DNA have no function and why we lost genetic abilities such as being able to produce our own Vitamin C.

So instead of the new gene being ATTCATTCAATTCATTCA, it's simply ATTCATTCA. You simply cannot have duplicates, just like computer files. I wish I could share an amazing video by PBS Eons giving a great explanation about genes and stuff, but sadly Brainly doesn't like such stuff, so just <em>search up in ㄚㄖㄩㄒㄩ乃乇 (ebuTouY) "genes we lost along the way" and it should be the first video that pops out.</em> Trust me, it's a great video, it's much better than my explanation.
