Answer: Sensory Neurone and a synapse
[tex]\Huge\text{1) Sensory Neurons}\\\\\Huge\text{2) Synapse}[/tex]
_____________________________________[tex]\Huge\textbf{Reflex Action:}[/tex]Reflex action is a involuntary and instantaneous action in response to a stimulus acting over a reflex arc. Some reflex actions are inherited and innate while other are acquired through learning processes. These reflex actions are performed without the will of the animal & generally involve minimum number of neurons.
Reflex Arc:Many neurons work in group called reflex arc, There must be atleast two neurons in a reflex arc. A reflex arc is made possibly a shortest pathway so the body acts on an impulse before it reaches the brain, and usually it is coordinated by spinal cord and brain-stem.
The parts of reflex arc is given as,
A receptor, a sense organ in the skin muscle or other organ.An afferent or sensory neuron, which carries impulses towards the central nervous system.The central nervous system, where a synaptic connections are made between the sensory neuron and the inter-neurons.The efferent or motor neurons which makes a synaptic connection with the inter neuron and carries impulses out from the central nervous system.The effector, by which the animal responds to the environmental changes.The change in the body is detected by receptors which gives the information to the brain or spinal cord which is the control center via the sensory neuron. The control center decides the appropriate response and sends it to the effector via motor neuron which plays its role.
_____________________________________[tex]\Large\textbf{Synapse:}[/tex]
a synapse is a small gap at the end of a neuron that allows a signal to pass from one neuron to the next. Synapses are found where nerve cells connect with other nerve cells or the muscle.

Which kind of evidence studies mineralized bone, footprints, or organisms trapped in amber to determine common
ancestry?
fossils
analogous structures
homologous structures
molecular clock
Answers
fossils are the right answer
The fossils helps to examine the mineralized bones, footprints, or organisms trapped in amber in order to determine common ancestry.
What are fossils?They are the remains or traces of ancient life, which have got preserved by natural phenomenon. It can be tiny sea shells to spectacular skeletons, tracks, imprints, and trails can also become fossilized like worm burrows or dinosaur footprints.
By examining the traces and remains of life one can learn a lot about the animals and plants that lived millions of years ago and their ancestry. The study of the history of life on the planet as based on fossils is known as paleontology.
Thus, the correct answer is fossils.

Use the scenario to answer the question.
A student is studying the effect of fertilizer on fruit growth. He uses 6 tomato plants, placing each in a garden where they get equal amounts of sun and water. One plant is given no fertilizer, while the other 5 plants are given 5, 10, 15, 20, and 25 grams of dissolved fertilizer each day for 3 weeks. At the end of the experiment, the tomato fruits are weighed.
What is the dependent variable in this experiment?
(1 point)
sun exposure
fruit weight
amount of fertilizer
amount of water
Answers
Answer:
fruit weight
Explanation:
In an experiment, the dependent variable is the variable that responds to the changes made to the independent variable. In other words, the dependent variable, as the name implies, is DEPENDENT on another variable called independent variable. The dependent variable is the variable that is measured or recorded by the experimenter during the experiment.
In this case where a student is studying the effect of fertilizer on fruit growth. He uses 6 tomato plants, which were given different concentrations of fertilizer (independent variable). After the experiment, the weight of the tomato fruit were measured. This means that the FRUIT WEIGHT is the dependent or responding variable.

because they are attracted by the smell of resin/ amber. they become trapped in the substance and the amber hardens
Answer:
the insects are attracted to the polysaccharide rich thick resin that seeps from the trees. This resin is highly nutritious but has one problem for the insects- its complete lack of viscosity. The thick resin entraps the insects at the bark, and the tree continues to grow outward and in doing so, fossilises the insect alive.

exchange
Explanation:
Your diaphragm, and muscles between your ribs, make air move in and out of your lungs. It travels through the trachea, bronchi, and bronchioles to alveoli. In the alveoli, oxygen diffuses into the blood and carbon dioxide leaves. This is gas exchange.
Air enters the lungs and leaves it as a result of the relaxation and contraction of the diaphragm and the muscles between the ribs. When both the muscles and the diaphragm relax, air enters from the trachea and travels through the bronchi and the bronchioles to the alveoli, where the oxygen in the air diffuses into the blood and carbon dioxide diffuse in the opposite direction. The entire process is known as gas exchange.

Lactase is an enzyme that many different animals have that helps digest the sugar lactose Why can this enzyme be the same in different species?
0 Lactase is necessary for survival of all organisms
0 All living things share a common code-DNA
0 Lactase is not regulated by external environments.
It is not possible for it to be the same in different species
Answers
Answer:
All living things share a common code-DNA
Explanation:
Enzymes are proteinous substances, which like every other proteins are encoded by a genes. In the expression of these genes, a set of codons (three nucleotide base) called GENETIC CODE is used. ONE of the characteristics of this genetic code is that it is NEARLY UNIVERSAL meaning that the same genetic code is used by virtually all known living organism.
According to this question, lactase enzyme, which helps digest lactose sugar in organisms, is the same in different organisms. This is due to the fact that all living things share a common code-DNA e.g AUG codes for methionine in all organisms, hence, when these DNA undergoes expression, it yields the same products in different organisms.

If you double the speed of an object, the kinetic energy increases by four times. The word "kinetic" comes from the Greek word "kinesis" which means motion. Kinetic energy can be passed from one object to another in the form of a collision.
Explanation:
The kinetic energy is proportional to the square of the speed, so doubling the speed increases the kinetic energy by a factor of 4.
