<u>ANSWER:</u>
The muscles and joints allow the hands to perform their function of holding and grasping a wide variety of things.
<u>EXPLANATION:</u>
- The structure of hands is "very delicate and complex". The tendons, nerve fibres, tissues and thin muscles are located right under the skin.
- The bones of the hand including the 4 carpal bones, 5 metacarpal and 14 finger bones are all connected by joints and ligaments and these allow the hand to grasp things.
- The wrist is made of "two parts of a joint" that allow the extension and stretching of hands.
Answer:
Ribosomes
Explanation:
This is the organelle for regulating protein synthesis in cells.It is made up of the small and big submits. These sub units collectively ensure the process of translation of protein my ensuing the correct synchronisation of condoms not he smaller nit of ribosomes with the anti codons on the tRNA with the to give a designated protein.
Therefore if there is mutation -deletion or substitution in the codons and anti codons,.this may affect bring frame shift which affects the protein translated leading to wrong protein formation.
Mitochondria is the organelle that gives the sperm power to swim.Therefore the protein that codes for mitochondrial is faulty and this affects the the tail from swimming properly.since ribosomes is the source of protein this is the correct answer
Answer:
The example of direct interaction between two organisms is in coral reefs some fishes behave as a cleaner for the other fish.
Explanation:
The fish eats the parasites which harms the other fish. In this the cleaner fish gets food and the other fish gets rid of parasites. The example of indirect interaction between two organisms is when the birds eat the caterpillar, there is a positive impact on the plants because the Caterpillars used to the leaf of the plants.
The direct interaction between two organisms is defined as when the action of one organism has a direct impact on the other organism. The indirect interaction between two organisms is defined as when the action of one organism is responsible for indirect impact on the other organism.
Meiosis is referred to as reduction division as it divides the chromosome number in half. Crossing over or recombination is the main reason of shuffled genes and increased genetic variation in gametes in meiotic cell division as the homologous pairs are paired up during prophase.
<h3>What is crossing over?</h3>
Crossing over is referred to as the exchange of genes of DNA between paired homologous chromosomes. It actually occurs during the development of egg and sperm cells i.e., during meiosis.
It is an enzyme-mediated step, in which the exchange of genetic material takes place between non-sister chromatids of homologous chromosomes.
It actually occurs at the pachytene stage of prophase I of meiosis cell division.
Thus, it can be concluded that the crossing over is the main reason of shuffled genes and increased genetic variation.

Answer:
The gene frequency for the albino allele is 16%.
Explanation:
Given that in a population with 100 rabbits there are 16 that are albino, with two recessive genes for albinism, to determine, in this population, what is the gene frequency for the albino allele, the following calculation must be performed:
16/100 = X
0.16 = X
1 = 100
0.16 = X
0.16 x 100 = X
16 = X
Therefore, the gene frequency for the albino allele is 16%.
