D. Mutations in sex cells are silent mutations.
SUBMIT
Answer:
A.
Explanation:
Mutations that happen in sex cells during meiosis are able to pass onto offspring.
"Mutations in sex cells can be passed on to children." Therefore, option (A) is correct.
What is mutation?A mutation in a sex cell differs from a mutation in a non-sex cell in that mutations in sex cells can be passed on to children. Sex cells, such as eggs and sperm, carry genetic information that is passed on to the next generation during fertilization.
If a mutation occurs in a sex cell, it can be transmitted to the offspring and can potentially affect the genetic makeup of future generations. On the other hand, mutations in non-sex cells, such as skin cells or liver cells, cannot be passed on to offspring because they do not contribute to the genetic material of the next generation.

Besides oxygen exchange, the respiratory system also functions to eliminate (Click to select) . Too much of this gas can cause a(n) (Click to select) in blood pH, compromising homeostasis.
Answer: Carbon dioxide, decrease
Explanation:
Cellular respiration is a set of reactions by which organic compounds (sugars) are degraded by oxidation to inorganic substances. This process provides energy in the form of ATP and to achieve this, many reactions occur in which electrons are passed from one molecule to another, called redox reactions. In the case of aerobic respiration, the final electron acceptor is molecular oxygen, which is reduced to water. Oxygen, like any gas, crosses the plasma membrane and then the mitochondrial membrane, and in the mitochondrial matrix it binds electrons and protons, forming water. It is in this final oxidation and in previous processes that energy is obtained. The reactions that extract energy from sugars such as glucose are catabolic reactions since a large molecule is broken into smaller molecules. For example, when glucose is broken down in the presence of oxygen, six molecules of carbon dioxide (CO2) and six molecules of water are obtained. Both CO2 and water are eliminated by lung exhalation.
In the event that this carbon dioxide is not completely eliminated, something called respiratory acidosis occurs, which is one of the disorders of the acid-base balance due to a decrease in the frequency of respirations or hypoventilation. The increase in the concentration of carbon dioxide in the blood causes the pH value to decrease. This scale is a measure of the degree of acidity or alkalinity of a substance or solution. A pH value of less than 7 means it is more acidic, and a pH value of more than 7 means it is more alkaline. Carbon dioxide is constantly produced as the body metabolizes energy, which will accumulate in the circulation rapidly if the lungs do not remove it properly. Alveolar hypoventilation thus leads to an increase in arterial CO2 partial pressure. The increase in pressure in turn decreases the ratio of bicarbonate (HCO3) to bicarbonate pressure with a consequent increase in acidity or decrease in blood pH. The body's metabolism rapidly generates a large amount of carbonic acid (H2CO3) and non-volatile acid. The lungs normally excrete the volatile fraction through ventilation without accumulation of acid in the blood but in this case this is not possible and this accumulation of carbonic acid causes the pH to rise. This disrupts homeostasis, a form of equilibrium that is achieved through a network of feedback control systems that constitute the self-regulatory mechanisms.
g Cerebrospinal fluid formed in the lateral ventricles travels through the ________ to reach the third ventricle.
Answer: Interventricular foramen
Explanation:
The cerebrospinal fluid is a fluid that covers the brain and spinal cord. It circulates through the subarachnoid space, the cerebral ventricles and the ependymal canal. Several diseases alter its composition and its study usually detects meningeal infections, carcinomatosis and hemorrhages. Some of its functions are:
Hydropneumatic support against local pressure for the encephalon.Eliminates metabolites from the central nervous system.Protects the central nervous system from trauma.This fluid also fills the ventricles, which are large open structures deep within the brain and help keep the brain buoyant and cushioned. The lateral ventricles are the largest ventricles and connect to the third ventricle through the intraventricular foramen. This third ventricle is a narrow, medial cavity located between the diencephalic masses. Then, the interventricular foramina are channels that connect with the ventricles of the lateral walls and with the third ventricle, at the level of the midline of the brain. Like these channels, they allow cerebrospinal fluid to circulate through the rest of the ventricular system of the brain. The walls of the foramina also contain choroid plexuses, responsible for the production of cerebrospinal fluid, which continue in both the lateral ventricles and the third ventricle. After reaching the third ventricle, the cerebrospinal fluid travels through the median aperture into the subarachnoid space at the base of the brain.

When the belt is moving at a high speed, 350 pills can be coated per hour. How many minutes would it take to coat all the pills in this batch at a high speed?
Answer:
6 pills are coated in one minute time.
Explanation:
There are 350 pills can be coated in 60 minutes due to high speed of belt movement which means that 6 pills are coated in one minute time period so if there are 60 pills so the belt takes 10 minutes to complete the coating of the pills. If there are 200 pills to be coated then we used the equation i.e.
6 pills -------- 1 minute
200 -------- x
By cross multiplication we get,
6x = 200 x 1
x = 200 / 6
x = 33.3 minutes
This means that in 33 minutes the belt can coated 200 pills.
