Answer:
atoms cells warmth or coolness then it would require some sort of foot print or a trace of it being there
Explanation:
Answer:
A neuron that has only one axon but several dendrites is classified as:
a. multipolar neuron.
Explanation:
- The neurons are the fundamental unit of the nervous system.
- The nervous system consist of only two types of cell; neurons and neuroglia.
- Neurons are specialized to respond to physical and chemical stimuli, conduct nerve impulse and release neurotransmitter , while the neuroglia supports , nourish and protect the neuron.
- Most neurons have three parts: a cell body, dendrites and axon.
- Neurons show a great diversity in size and shape, and are classified on the basis of structure and function.
On the Basis of structure the neurons are classified as: unipolar, bipolar and multipolar. (Multidendritic neurons are studied in <em>Drosophilla </em>and are reported to be a result of misexpressed<em> gene</em>)..
- Multipolar neurons are the most common type of neurons in the brain and spinal cord and have several dendritic processes and one axon.
- Bipolar neurons are found in retina of the eye, in the inner ear and in the olfactory area of the brain and are characterized by one dendrite and one axon.
- Uni-polar neurons have single processes extending from the cell body which divide into two branches.
On the basis of function neurons are classified as; sensory, motor and association neurons.
Answer: It occurred a dihybrid cross and epistasis.
Explanation: In dihybrid cross, two different genes controlled two different traits. When they interact with each other is called Epistasis. However, in wheat plants, the genes related to color kernels don't act opposedly to each other. In other words, the genes have the same role in producing protein, so they can substitute for each other.
In the color determination mechanism, a biochemical reaction is necessary to convert a precursor substance into a pigment and that reaction happens with the product of either genes. That's why having a dominant allele makes the wheat colorful. So, crossing colored kernels with white ones will produce a heterozygous F1 generation. Crossing this generation will produce a F2 generation with modified ratio of 15 colored: 1 non colored because, every individual who has dominant alleles will produce the substance and thus the biochemical reaction will happen. Only recessive homozygous ones won't have the substance and so won't have color.
They can either be protons (positive) or electrons (negative)
Answer:
<u>Areas where lava recently flowed, a glacier retreated, or a sand dune formed.</u>
Explanation:
I don't know if this'll help you, but I think that should be somewhat about primary succession.
