Zanzabum

Answer:

There are different types of reflexes, and some of them can be controlled voluntarily due to cortical processing.

Explanation:

Even if there is an initial myotactic reflex of moving away from the heat, the cortical processing that is subject to learning makes you not let go of the pan. It should be noted that there are different types of reflexes, and not all postural reactions are automatic. The cerebral cortex influences voluntary postural adjustment movements. Such control is mainly performed by the brain stem, where ocurrs the modulation of motor neurons and spinal cord interneurons through the lateral descending (fine movements) and medial (posture and balance) downward pathways.

Which curve shows the course of the reaction in the presence of an enzyme--the black curve or the red curve? Which line represen
nikklg [1K]
I found the attached image on the internet and it really helps complete this exercise.

First question:
In the presence of an enzyme, the course of the reaction is shown by the red curve. The necessary energy to make a reaction occur is less when there is an enzyme to help the reaction happen. Enzymes work as catalysts that act over substrates converting them into different molecules in a much accelerated way then it would happen without the enzyme's help, if it would happen at all.

Second question:
The activation energy is represented by line B. The activation energy is the energy needed to be available for a reaction to happen. If we compare it with line A, which represents the activation energy necessary for a reaction without an enzyme, we can see how much less energy is necessary to dispend when an enzyme is part of the reaction. Line C represents the energy resultant from the reaction.

How do the respiratory and excretory systems work together to help people grow and survive
LUCKY_DIMON [66]

Answer:

respiratory and excretory systems are among the two vital systems in our body which work in order to maintain our health or keep our body fit

Explanation:

Respiratory systems comprises of organs like lungs to inhale oxygen and exhale carbon dioxide out of our body. The oxygen is then mixed with blood by the heart and reaches different parts of our body.

Excretory system is responsible for excreting or expelling the waste out of our body to keep our body free from toxins and harmful chemicals.

excretory system works with respiratory system to get rid of water vapors and carbon dioxide in the human body.

Why are most of the stomata on the bottom of the leaf
larisa86 [58]

Answer: Stomata plays very crucial roles in plants. During photosynthesis, gas exchange takes place via the stomata. Water also evaporates from plants through the stomata. In plants, most of the stomata are usually on the bottom of the leaf IN ORDER TO PREVENT EXCESSIVE LOSS OF WATER.

During the day, the sunlight falls on the leaf directly and draws water from the plants. Locating the stomata at the underside of the leave reduces the amount of water that can be lost through excessive evaporation. Also, locating the stomata on the underside of leaves prevent  the leaves from taking in too much water during rainfall.

Please help me on both questions. i don’t know at all and i’m so confused
Mademuasel [1]

Answer:

cant really answer much since you need the class results for these. but i can simplify question 1. so, does the class results prove that the traits made my dominant alleles are the most common? or in other words, are traits made  by dominant alleles most common in the class results?

number 4 is yes because there are more possibilities that the dominant trait will occur than the recessive trait. therefore, it is more common and the conception is correct
