Answer:
Well, Earth is the same way! Earth is made up of several different layers, each of which has unique properties. Both parts of the core are made up of mostly iron and some nickel. The difference is that in the inner core, those minerals are solid and in the outer core, they're liquid.
Question 4: Each parent would contribute one allele
Question 5: A white flower allele is presented in both homologous chromosomes (it would have to be in both because it is recessive)
The correct answer is: sea stars
All animals listed above are invertebrates. One of the characteristic of invertebrates are that they are protostomes with the exception of Echinodermata (sea stars). The difference between protostomes and deuterostomes is in their embryonic development (orgin of mouth and anus).
In protostomes the mouth forms first: the oral end of the animal develops from the first developmental opening. On the other hand in deuterostomes the first opening (the blastopore) becomes the anus, and the oral end of the develops from the second opening.
Humans are also deuterostomes.
Answer:
because parents only give the child 1/2 of their chromosomes
Explanation:
Answer:
The muscle has two, three, or four origins, respectively.
Explanation
- A muscle is an organ composed of muscle tissue that contract to facilitate a particular movement
- biceps,triceps and quadriceps are types of skeletal muscles since they use bones as levers
- <em><u>They differ in that; the biceps have two origins, triceps have three origins and quadriceps have four origin.</u></em>
- <em><u>Bicep is a two headed muscle thus said to have two origins ,triceps have three muscle heads and therefore have three separate origin attachment point while quadriceps are made of four muscles heads hence have four origins. </u></em>
