Answer:
a
Explanation:
When a gene mutation occurs, the nucleotides are in the wrong order which means the coded instructions are wrong and faulty proteins are made or control switches are changed. The body can't function as it should. Mutations can be inherited from one or both parents. They are present in the egg and/ or sperm cells.
The correct answer is A. Apical meristem
Explanation:
In plants, the primary growth refers to the type of growth that increases the length of the stem or toots in opposition to the secondary growth in which the stem thickens and that occurs as the result of the vascular cambium. However, in the case of primary growth, this can be explained mainly due to the action of apical meristem that is a type of tissue located in the tips of roots and the stem and therefore the type of tissue in which the growth takes place mainly through cell division. Considering this, it can be concluded primary growth is due to the action of the apical meristem.
Answer:
I believe it is Anaphase 1
Explanation:
Anaphase is the stage of meiotic or mitotic cell division in which the chromosomes move away from one another to opposite poles of the spindle. This is the process that separates the duplicates genetic material carried in the nucleus of a parent cell into two identical daughter cells.
These groups are arranged in order from most inclusive (most general) to least inclusive (most specific) is gnathostomes, osteichthyans, lobe-fins, tetrapods, amphibians.
<h3>What is
gnathostomes?</h3>
The jawed vertebrates are called gnathostomata. The phrase comes from the Greek words "jaw" and "mouth." Approximately 60,000 species make up the diversity of the gnathostome, which represents 99% of all vertebrates still alive today.
<h3>What is
osteichthyans?</h3>
A broad taxonomic group of fish called osteichthyes, also known as the "bony fish," has skeletons that are predominantly made of bone tissue.
<h3>What is
lobe-fins?</h3>
The taxon Sarcopterygii, also known as Crossopterygii, is made up of bony fishes noted for having lobe-finned fishes as its members.
<h3>What is
tetrapods?</h3>
Four-legged vertebrates that make up the superclass Tetrapoda are known as tetrapods, which derives from the Ancient Greek (tetra-) "four" and "foot." It consists of synapsids, dinosaurs, and extinct as well as living amphibians, reptiles, and dinosaur-related birds (including mammals).

Answer: conditioned
Bobby touches his newborn brother's palm, and his little brother takes hold of Bobby's finger and will not let go. This is known as the conditioned reflex.
Explanation:
A conditioned reflex is a response or behaviour learned after birth. So, once the newborn acquires this learned response, they can perform them even without thinking about it.
Thus, Bobby's brother (the newborn) holding on to his finger and not letting go shows that it is a conditioned reflex
