Answer:There is no scientific basis to the claim sometimes made that the biological evolution of mankind has stopped, or nearly so, at least in technologically advanced countries. It is asserted that the progress of medicine, hygiene, and nutrition have largely eliminated death before middle age; that is, most people live beyond reproductive age, after which death is inconsequential for natural selection. That mankind continues to evolve biologically can be shown because the necessary and sufficient conditions for biological evolution persist. These conditions are genetic variability and differential reproduction. There is a wealth of genetic variation in mankind. With the trivial exception of identical twins, developed from a single fertilized egg, no two people who live now, lived in the past, or will live in the future, are likely to be genetically identical. Much of this variation is relevant to natural selection (5, 8, 9).
Natural selection is simply differential reproduction of alternative genetic variants. Natural selection will occur in mankind if the carriers of some genotypes are likely to leave more descendants than the carriers of other genotypes. Natural selection consists of two main components: differential mortality and differential fertility; both persist in modern mankind, although the intensity of selection due to postnatal mortality has been somewhat attenuated.
Death may occur between conception and birth (prenatal) or after birth (postnatal). The proportion of prenatal deaths is not well known. Death during the early weeks of embryonic development may go totally undetected. However, it is known that no less than 20% of all ascertained human conceptions end in spontaneous abortion during the first 2 mo of pregnancy. Such deaths are often due to deleterious genetic constitutions, and thus they have a selective effect in the population. The intensity of this form of selection has not changed substantially in modern mankind, although it has been slightly reduced with respect to a few genes such as those involved in Rh blood group incompatibility.
Postnatal mortality has been considerably reduced in recent times in technologically advanced countries. For example, in the United States, somewhat less than 50% of those born in 1840 survived to age 45, whereas the average life expectancy for people born in the United States in 1960 is 78 y (Table 1) (8, 10). In some regions of the world, postnatal mortality remains quite high, although there it has also generally decreased in recent decades. Mortality before the end of reproductive age, particularly where it has been considerably reduced, is largely associated with genetic defects, and thus it has a favorable selective effect in human populations. Several thousand genetic variants are known that cause diseases and malformations in humans; such variants are kept at low frequencies due to natural selection.

Which type of authentication method is commonly used with physical access control systems and relies upon RFID devices embedded into a token
The type of authentication method commonly used with physical access control systems and relies upon RFID devices embedded into a token is known as RFID authentication or RFID access control.
RFID stands for Radio Frequency Identification, which is a technology that uses electromagnetic fields to identify and track objects that have RFID tags attached to them. In the case of physical access control systems, RFID devices are embedded into a token, such as an access card or key fob, which is used to gain entry to a secure area.
To gain access, the token is held near an RFID reader, which reads the unique identifier on the token and verifies it against a database of authorized users. If the token is re
cognized as belonging to an authorized user, the access control system grants access.
RFID authentication is a popular and effective method of physical access control as it is relatively easy to use and can quickly grant or deny access to a large number of users. Additionally, it can provide a high level of security by allowing access to only authorized personnel and providing an audit trail of entry and exit times.

Explanation:
Packet Transmission Delay. Consider the network shown in the below, with two senders on the left sending packets to a common receiver on the right. The links have transmission rates of R₁ R₂ = 100 Mbps (i.e.. 100 x 106 bits per second). Suppose each packet is 1 Mbit (105 bits) in size. How long does it take a sender to transmit a packet into its link (i.e., the packet transmission delay at the sender)? O 1 sec O.1 sec 01 sec O 106 msec 100 sec
The packet transmission delay at the sender is 0.01 seconds or 10 milliseconds. The packet transmission delay at the sender can be calculated by dividing the size of the packet by the transmission rate of the link.
To calculate the packet transmission delay at the sender, we divide the packet size by the transmission rate of the link.
Packet Transmission Delay = Packet Size / Transmission Rate
In this case, the packet size is 1 Mbit (105 bits) and the transmission rate is 100 Mbps (100 x 106 bits per second).
Packet Transmission Delay = 105 bits / (100 x 106 bits per second)
= 1 / (100 x 10^-2) seconds
= 1 / 100 seconds
= 0.01 seconds

It is mentioned in Section 4.6.6 that the efficiency of a 1-slot frame with repetition encoding is about 13% at basic data rate. What will the efficiency be if a 5-slot frame with repetition encoding is used at basic data rate instead
The efficiency of a 5-slot frame with repetition encoding used at basic data rate is 12.5%, which is significantly higher than that of a 1-slot frame with repetition encoding.
Step-by-step explanation:
In the text, it is stated that the efficiency of a 1-slot frame with repetition encoding is about 13 percent. In contrast, if a 5-slot frame with repetition encoding is used at basic data rate instead, we may compute the efficiency as follows.
The duration of a single slot in the time-division multiple access (TDMA) scheme is determined by the data rate, which is defined as the number of bits per second. As a result, if a basic data rate is defined as R bits per second, the duration of one slot T would be:
T = (L/R) seconds
where L is the length of the frame in bits.
As a result, if we assume that a slot is long enough to transmit a single packet (i.e., a packet cannot be divided across multiple slots), the length of a frame in bits L would be:L = 1 slot × b bits per slot
where b is the size of the packet in bits.
To increase the probability of correctly receiving the packet, repetition encoding is used. Specifically, each bit is repeated N times before being sent, and the receiver tries to estimate the original bit from the noisy received bits. Since N repetitions are used, each packet is N times longer, and the effective data rate is decreased by N times.
As a result, the length of the frame is extended to L = N × b bits, but the time it takes to transmit the packet is still the same: T = (L/R) seconds.
As a result, the efficiency of a single-slot frame with repetition encoding can be calculated as follows:
efficiency = (number of useful bits) / (number of transmitted bits)
number of useful bits = b
number of transmitted bits = L × N = N × b
Therefore, the efficiency of a single-slot frame with repetition encoding is given by:
efficiency = b / (N × b) = 1/N
For example, if N = 8, the efficiency would be:
efficiency = 1/8 = 12.5 percent
If we utilize a 5-slot frame, we may transmit five packets in a row without having to compete for the channel.
As a result, the total number of bits that can be sent during the five-slot frame is five times higher than that of a single-slot frame. However, since the length of each packet is also multiplied by N, the overall length of the five-slot frame would be L = 5 × N × b bits. The effective data rate is the same, thus the length of the frame is:
T = L/R = 5 × N × b/R seconds
Therefore, the efficiency of a five-slot frame can be calculated as follows:
efficiency = (number of useful bits) / (number of transmitted bits)number of useful bits = 5 × b
number of transmitted bits = 5 × N × b
Therefore, the efficiency of a five-slot frame with repetition encoding is given by:
efficiency = 5 × b / (5 × N × b) = 1/N
As a result, the efficiency of a five-slot frame with repetition encoding is the same as that of a single-slot frame with repetition encoding. If N = 8, for example, the efficiency would be:
efficiency = 1/8 = 12.5 percent.

What is a named sequence of insturctions thay may take inputs and may reportavalue?
A named sequence of instructions that may take inputs and may report a value is known as a function.
Functions are fundamental building blocks in programming that allow you to organize code into reusable and modular units. They encapsulate a set of instructions and can be called or invoked from different parts of a program, providing flexibility and code reusability. In programming languages, functions are defined with a name and can take zero or more input parameters, which are values passed to the function for processing. These parameters are optional and can be used to customize the behavior of the function. The instructions within the function define the logic and operations to be performed. Functions can also return a value as a result of their execution, which can be used in the calling code. Functions enable code abstraction and promote code readability by breaking complex tasks into smaller, manageable parts. They allow developers to write modular code and improve code maintainability and reusability. By organizing code into functions, you can isolate specific tasks, promote code encapsulation, and make code easier to understand and debug.
