Answer:
A- Sensory Neuron
B- Spinal cord
C- Effector neuron
D - Brain
Explanation:
- Sensory neuron: Its main function is to allow the reception of stimuli that are transformed into nervous impulses and electrical signals, capable of realizing sensations, such as a peliscão, for example. These impulses are transmitted to the spinal cord.
- Spinal cord: The main function is to support the body in an upright and vertical position. It also has the function of transmitting electrical signals and nerve impulses between some parts of the body and the brain.
- Effector neuron: Its main function is to receive muscle stimuli capable of creating muscle contractions. These neurons are located in the spinal cord.
- Brain: the processing center receives all the stimuli sent by the bone marrow. Its main function, in this case, is to produce bodily responses to the stimuli it has received, producing muscle movement.
Answer:
d
Explanation:
Fishes are aquatic vertebrates having scales, pharyngeal gill slits and paired fins. ... Most fish are ectothermic ("cold-blooded"), allowing their body temperatures to vary as ambient temperatures change. fishes have scales that covers the skin of fishes. Thus, the correct answer is option D.
<u>4NH3 + 5O2 → 4NO + 6H2O</u> is the correct balanced equation in the given chemical equation options.
What do you mean by Chemical equations?
A chemical equation is a written representation of the chemical reaction taking place between two or more substances. It can be written in words or symbols, and typically consists of the reactants (on the left side) and the products (on the right side). The arrow between them indicates the direction of the reaction.
The above equation is balanced because it has the same number of atoms of each element on both sides of the equation. The equation is balanced because it has 4 atoms of nitrogen (N) on the left side and 4 atoms of nitrogen on the right side. It has 5 atoms of oxygen (O) on the left side and 6 atoms of oxygen on the right side. It also has 3 atoms of hydrogen (H) on the left side and 12 atoms of hydrogen on the right side.

Answer:
Chromosome number variation: B. Down syndrome
Loss-of-function allele : D. PKU
Physiological trait
: E. Lactose metabolism
Discovery-based science
: A. Human Genome Project
Genetic cross: C. Model organism
Explanation:
Down syndrome is a condition in which there is an extra copy of the chromosome number 21. Hence, it is a chromosome number variation.
Physiological traits refers to any function of a body. Hence, it matches with lactose metabolism.
Human Genome Project was a project under which the whole genome of the humans were sequenced. Hence, it is a discovery based science.
A genetic cross is made between model organisms to test for the offsprings that would be produced from a cross. Hence, genetic cross and model organism math with each other.
Answer:summer
Explanation north is facing the sum where the light reaches closest making it summer in the north and winter in the south
Summer
