Answer:
Pneumotaxic centre in the pons region of the brain can moderate functions of the respiratory rhythm centre. Neural signals from this centre can reduce the duration of inspiration and thereby alter the respiratory rate. A chemosensltive area is situated adjacent to the rhythm centre to make necessary adjustments in the respiratory process. Receptors associated with aortic arch and carotid artery also can recognise changes in CO
2
and H+ concentration and send necessary signals to the rhythm centre for remedial actions. The role of oxygen in the regulation of respiratory rhythm is quite insignificant.
So, the correct answer is 'Both Assertion and Reason are correct and Reason is the correct explanation for Assertion'.
Explanation:
Answer:
this means that the oxygen is maintained by the respiratory rhythm.

Wall lizards are not seen during cold, Why?
Wall lizard are not seen because blood becomes cold inside the body.
Answer:
Lizards are cold-blooded. They use their enviornment to control their body temperature. If a lizard is cold, it will go somewhere warmer. If a lizard is hot, it will go someone to cool off.
The lizard may find somewhere in direct sunlight, bury themselves in a hole, or bury themselves under leaves to keep warm.
. Transform these false statements into ones that are true (A) Most people who exhibit abnormal behavior are not particularly troubled by it. (B) The terms "insanity" and "abnormal behavior" mean the same thing.
The true statement of option A is as follows: Most people who exhibit abnormal behavior are particularly concerned about it.
A person with abnormal behavior is not necessarily sick and careless; his behavior is different from that of the majority of the population.
The true statement of option B is as follows: The terms "insanity" and "abnormal behavior" do not mean the same thing.
The madness of a person is usually caused by a serious mental disorder where the person loses his mind and is totally unaware of what he is doing, it can end up with his own life, on the other hand, abnormal behavior usually implies a change behavior or the way a person reacts to a situation that is generally not common to most people.
Why do producers (plants) have an opportunity to thrive after wildfires?
Answer:
Thick bark.
Trees in fire-prone areas develop thicker bark, in part, because thick bark does not catch fire or burn easily. It also protects the inside of the trunk
Fire-induced sprouts.
This fire-survival strategy allows for the complete destruction of above-ground growth

A cytoskeleton is:_______.
a. a structure that aids in the process of cell division.
b. found in the cytoplasm of eukaryotic cells.
c. a system of tracks used for transport.
d. composed of microtubules and microfilaments.
e. All answers are correct.
Answer: e
Explanation: Cytoskeleton is a microfilaments, intermediate filaments, and microtubules that provide support and movement for eukaryotic cytoplasm.
1. Prokaryotic cytoplasm lacks certain features of eukaryotic cytoplasm, such as cytoskeleton and cytoplasmic streaming.
2. The cytoskeleton provides support and shape to cell.
3. It help in transporting substances through cell.
4. It help in phagocytosis.
5. It help in cytoplasmic streaming that is movement of eukaryotic cytoplasm from one part of cell to another which help distribute nutrients and move the cell over the surface.
6. The study of the numerous interaction between microbes and host cell cytoskeleton is a very intense area of investigation on virulence mechanism.
All answers are correct. Therefore, option (E) is correct.
What is cytoskeleton?The cytoskeleton is a complex network of protein filaments that extends throughout the cytoplasm of eukaryotic cells. It plays a number of important roles in the cell, including providing structural support, helping cells maintain their shape, and assisting in the movement of organelles and other cellular components. The cytoskeleton is also involved in the process of cell division, or mitosis, which is the process by which a single cell divides into two daughter cells.
The cytoskeleton is composed of three types of protein filaments: microtubules, microfilaments, and intermediate filaments. Microtubules are long, thin protein fibers that form a kind of scaffolding within the cell. Microfilaments, which are made of actin proteins, are thinner than microtubules and are involved in muscle contraction and cell movement. Intermediate filaments are thicker than microfilaments and provide structural support to the cell. Together, these three types of protein filaments form a system of tracks that can be used for transport within the cell.

A. Fossil fuels provide cheaper energy.
B. We have very efficient means of using fossil fuels currently.
C. We already have infrastructure in place to make use of fossil fuels.
D. Fossil fuels provide cleaner energy.
Explanation:
A ) Fossil fuels provide cheaper energy
MARK AS BRAINLIST IF IT IS USEFUL .
Fossil fuels are a non-renewable resource that takes years to form. They are the source of large energy production and provide cost-efficient cheaper energy. Thus, option A is correct.
What are fossil fuels?Fossil fuels are the dead remains that got converted into sediments and over millions of years produced the fuels used to drive energy. They are produced from deposition of the organic matter and are widely used resources for energy.
They are present in the crust of the earth and are a cheaper form of energy than wind and geothermal energy. They are found in the form of coal, petrol, diesel, and other natural gases. They are produced from decaying organic matter.
These fuels are less costly than the alternative form of energy, however, are the reason for increased temperature and climate change. They have added to the greenhouse gases and are major pollutants.
Therefore, option A. fossil fuels are cheaper.

What are similarities and differences between insects that go through complete metamorphosis and incomplete metamorphosis?
There are two types of metamorphosis-incomplete and complete.
In incomplete metamorphosis, an adult insect lays an egg. The egg hatches into a nymph, which is like a mini adult. This nymph then grows into an adult. As the nymph grows, it molts several times. Grasshoppers are examples of insects that undergo incomplete metamorphosis.

What is the frequency of a wave that has a wavelength of .20 m and a speed of 22 m/s
Answer:
110 Hz
Explanation:
Find the frequency of the wave using the formula, frequency = speed / wavelength.
Plug in the speed and wavelength, and solve:
frequency = speed / wavelength
frequency = 22 / 0.2
frequency = 110
So, the frequency of the wave is 110 Hz
