Answer:
It has four layers and attach with each other with desmosome.
Explanation:
The keratinocytes are arranged in four different layers which are the stratum basale, stratum spinosum, stratum granulosum, and stratum corneum. These cells are attached with desmosome which is a membrane protein. The presence of these four layers made a barrier against damage done by heat, UV radiation, water loss, pathogens etc. There are fewer cells at the end of the time as compared to the start because may be of the water pressure on the membrane or these cells for a long time.
The right option is b. mutualism
Mutualism is a relationship
between two organisms of different species in which both organisms benefit from
the relationship. From the question given above, both the oxpeckers and the
zebras benefits from the relationship. This type of relationship describes
mutualism.
Answer:
A mutation that causes a single letter change in the DNA sequence can affect your protein structure and function because the sequence of letters in a gene determines the sequence of amino acids in the protein that it encodes. A single letter change in the DNA alters the mRNA which alters the amino acid sequence of the resulting protein and sometimes that can cause serious results if it changes the way a protein works.
It is the cerebellum’s duty to receive information from the sensory systems, the spinal chord, and other parts of the brain. After receiving all the information from those parts, the cerebellum will then regulate the motor movements. It is the work of the cerebellum to coordinate voluntary movements such as posture, balance, coordination, and speech, resulting in smooth and balanced muscular activity. It also has some roles such as storing learned sequence of movements, participates in fine tuning and coordination of movements produced elsewhere in the brain and it integrates all of these things to produce movements. Because of the harmonious and fluid coordination of all the movements caused by the cerebellum, we are not even aware that we are doing those actions. The cerebellum is responsible and is important in learning and implementing of the motor skills.
They us machines like AUVs and research vessels because the ocean is so deep sometimes they can’t even research their experiment therefore they lean towards technology helping scientist experiment the ocean however we’ve only discovered 1% of the ocean and the 99 % is unknown because the ocean is so deep
