when there is high concentration of co2 in our body then respiratory centre ( medulla and pons) get activated and it increase rate of respiration which decreases co2 concentration
The apneustic (stimulating) and pnuemotaxic (limiting) centers of the pons work together to control rate of breathing.
What is medulla?Medulla is defined as the lowest part of the brain and the lowest portion of the brainstem. The medulla oblongata is connected by the pons to the midbrain and is continuous posteriorly with the spinal cord, with which it merges at the opening (foramen magnum) at the base of the skull.
The medulla sends signals to the muscles that initiate inspiration and expiration and controls nonrespiratory air movement reflexes, like coughing and sneezing.

The reason for the length of day and night is the diurnal rotation because the sun cannot illuminate the whole earth at once when the earth is lit on one side it is day and when it is on the other side it is night
Answer:
Yes.
Explanation:
Yes, the sun cannot illuminate the whole earth at once when the earth is lit on one side it is day and when it is on the other side it is night. The earth rotates on its own axis which causes change of day and night. Due to this rotation, those areas which are in front of sun experience day while on the other hand, the shade part of the earth causes night at that part so we can say that diurnal rotation is responsible for day and night.

What helps an animal to look like another animal to stay protected from predators? *
(0/1 Point)
Answer: ADAPTIVE COLORATION
Explanation:
Colour and colour patterns play an important role in adaptations of animals. Such adaptive coloration is due to the presence of pigments in cells called CHROMATOPHORES. These cells are involved in coloration and color change which helps an animal to look like another animal to stay protected from predators.
Adaptive coloration may be grouped into :
--> WARNING COLORATION: some animals display bright colours and patterns that announce their presence rather than conceal it. Example is the yellow and black stripes of yellojackets and other wasps which have very painful stings.
--> MIMICRY: colours and patterns are used extensively by mimics. For example, the foul-tasting Actaea butterfly and the poisonous African monarch are mullerian mimics. They resemble each other closely because they have similar colouring and patterns on their bodies.
--> CONCEALING COLORATION: This is used in camouflage. It helps an animal to remain unnoticed by the predator. Certain animals change the colour of their body surfaces to match their environment and so escape detection.

A. increase the size of the muscle cells and the amount of blood that is delivered to the muscle B. decrease the amount of fuel that the muscle can store and increase the time it takes for the muscle to contract C. increase the number of muscles and decrease the size of the muscle cells D. decrease the length of the muscle and increase the thickness of the muscle
Answer:
The correct answer is - A. increase the size of the muscle cells and the amount of blood that is delivered to the muscle.
Explanation:
Muscular endurance is the ability of a muscle to do some work or exert force continuously and rapidly for a period of time. To increase muscular endurance no heavy exercise required by including exercises that can help in increasing the size of the muscle cells and the amount of blood that is delivered to the muscle. The size of cells and delivering a high amount of blood helps in getting more oxygen and perform the metabolic activity more and generate more energy. So including the exercise rapidly and continuously will help in increasing the muscle cells.

Fungi live by
A. Making their own food.
B. Eating other organisms.
C. Sucking up nutrients made by other organisms.
Answer:
C
Explanation:
Fungi are heterotrophic.
Fungi are not able to ingest their food like animals do, nor can they manufacture their own food the way plants do. Instead, fungi feed by absorption of nutrients from the environment around them. Most fungi are saprophytes, feeding on dead or decaying material.
Answer:
C. Sucking up nutrients made by other organisms.
Explanation:
Fungi (singular: fungus) are a kingdom of usually multicellular eukaryotic organisms that are heterotrophs (cannot make their own food) and have important roles in nutrient cycling in an ecosystem.
It could be other plants or animals where they get a great place to source their food.
During this time, the fungi kind of hibernates until they get a suitable and beneficial place they can transfer to.

Which statement best describes Earth's human carrying capacity?
A: It is a fixed number that we will soon exceed.
B: It is increasing due to improved technology and medicine.
C: It is decreasing due to increasing population.
D: It is decreasing due to decreasing death rates.
The statement that best describes Earth's human carrying capacity that it is increasing due to improved technology and medicine. The correct option is B.
What is carrying capacity?Carrying capacity is the amount of persons the individual may experience over a lengthy amount of time and density affects the overall population.
Food, habitat, moisture as well as other necessities found in the environment determine carrying capacity.
Carrying capacity is defined as the average population size of a species in a given habitat.
Environmental factors such as adequate food, shelter, water, and mates limit the species population size. If these needs are not met, the population will decrease until the resource rebounds.
The best description of Earth's human carrying capacity is that it is increasing as a result of improved technology and medicine.
Carrying capacity is defined as the maximum number of individuals of a population that the environment can support.
Thus, the correct option is B.

Meiosis in males produces four identical sperm cells.
A. True
B. False
Answer:
B. False
Explanation:
Meiosis in males, not produces four identical sperm cells.
Meiosis is a type of cell division which involves the reduction in chromosomal content to half. The four daughter cells formed in meiosis are not identical. Thus, the given statement is false.
What is Meiosis?Meiosis is a type of cell division in which the number of chromosomes reduces by half than that present in the parent cell and produces four haploid gamete cells. This process is required to produce both male and female gametes- egg and sperm cells for sexual reproduction.
During the telophase II- last phase of meiosis, cell division is incomplete without another round of cytokinesis. Once the cytokinesis is complete there are four daughter cells, each with half a set of chromosomes (haploid) which are different due to the crossing over between chromatids.

Basalt
Limestone with unknown fossil
Sandstone with trilobite
Shale with ammonite
Based on the provided information, the rock layers can be arranged from oldest to youngest as follows: shale with ammonite (oldest), Limestone with unknown fossils, Sandstone with trilobite, and basalt (youngest).
This arrangement is based on the principle of superposition, which states that in an undisturbed sequence of sedimentary rocks, the oldest rocks are found at the bottom and the youngest rocks are found at the top. Since the shale with ammonite is mentioned first and the basalt is mentioned last, we can infer that the shale layer is the oldest and the basalt layer is the youngest among the given options.
