Draw a flowchart that explains how Tom’s nervous system controls his actions. As part of the flowchart, write one or two sentenc
Katarina [22]
<h2>Answer 1 with Explanation </h2>

The nervous system help the body to respond to different stimuli because its function is to coordinate with all the body parts. It has four primary functions that relate to the areas of the body in every human being for which the system handles information. The sensory function allows the body to collect information from outside or within the body.

<h2>Answer 2 with Explanation </h2>

Tom steps into the haunted house- the brain receives information from different parts of the brain and interprets it to generate the emotion of fear and then sends impulses to different parts of the body to trigger a flight response. Organisms that fear and make a flight response are more likely to survive. Later then the nervous system interprets the information to the brain through the spinal cord.

<h2>Answer 3 with Explanation </h2>

Tom feels his heart pumping and his breathing speed up because of the sympathetic nervous system stimulates adrenal glands that trigger and releases adrenaline which results in an increase in heart rate, blood pressure, and breathing rate. The integrative function is about how the collected information is being interpreted in Tom.

<h2>Answer 4 with Explanation </h2>

Tom jumps when he sees the costumed character. This is due to flight response in an individual, unleashes powerful hormones are released that affect the whole body from which signals are transferred to the brain and then it causes an involuntary jump in the muscles of the individual. The reasoning of this is that Tom's brain responses in a shock when he sees the character.

<h2>Answer 5 with Explanation </h2>

Tom runs out of the haunted house The reason of this is that Tom runs when the brain makes his muscles move by sending electrical signals to them through the nerves and this kind of involuntary actions happen really quickly so that the action takes place faster. At last, the nervous system helps to determine the motor function in which the effectors are able to respond.

Nat2105 [25]

Answer:Recessive traits

Explanation: Albinism is a reccessive traits whose effect have been suppressed by the dominant traits in the parents phenotype.

Complete dominance occurs when an allele A completely dominate over allele a in the genotype of an organism.

For the parents to have given birth to a non albino it means they are heterozgous dominant(Aa) and a cross between two heterozygous dominant parents will result in one homozgous non albino,2 heterozygous non-albino and 1 homozygous albino with the phenotypic ratio of 1AA 2Aa,1aa

At which type of plate boundary do tectonic plates slide past each other?
melamori03 [73]
The answer would be conservative plate boundaries.

They occur where plates slide past each other in opposite directions, or in the same direction but at different speeds. Friction is eventually overcome and the plates slip past in a sudden movement. The shockwaves created produce an earthquake.

I hope this helped and is correct! :)

Explain the purpose of the placenta and describe how a fetus gets its nutrients.
marusya05 [52]

Answer:

The placenta is the temporary association of fetus and maternal tissue. It is meant for nutrition and transport of different substances.

Explanation:

The placenta is a temporary association of fetal and maternal tissues. The placenta is formed from the trophoblast of the blastula. These trophoblasts   form chorionic villi which later forms the placenta. The chorion and allantois also take part in the formation of the placenta. Hence, the human placenta is known as the chorioallantoic placenta. The process of formation of the placenta is known as placentation.  

The placenta has several functions but the major function is to provide nutrition to the fetus. The developing fetus gets nutrition from the mother's body by the placenta. The placenta provided with blood vessels which help in the transportation of different substances. It also helps in gas exchange between the mother and baby. Thus it plays a vital role in fetal respiration. The metabolic wastes diffuse through the placenta. Placenta also stores fat, glycogen, which participates in protein metabolism.
