true
Explanation:
According to the gate control theory, what is one reason we are able to block the perception of pain?
Answer:
Gate theory claims that pain sensations must pass through a space, or gate, in the spinal cord, which can be closed to block pain signals sent from the brain or peripheral receptors.
Explanation:
According to the gate control theory, the activities of large fibres cause the excitation of inhibitory neurons. This reduces the transmission of pain signals.
What is gate control theory?
This is a type of defence mechanism by our nervous system. In this mechanism, the signals that are sent to the brain, by the spinal cord for the perception of pain, are managed by the spinal cord itself.
This may include the mechanism of reducing or increasing the pain. Therefore, the gate theory can heighten or decrease the perception of pain meaning the gate can either be closed or it can be open. The pain signals will pass to the brain if the gate is open and they will be restricted to the spinal cord if the gate is closed.
A painful or noxious stimulus of pain can be restricted or managed by a non-noxious stimulus. Like a backache can be managed by a gentle back massage.
Therefore, a gate control mechanism helps in blocking the perception of pain in the spinal cord.

movement through the cell cycle is not controlled in the cells?
True or False
Answer:
False is the correct answer
Cell-cycle control is entirely dependent on post-transcriptional mechanisms such as phosphorylation of Cdk activity and the binding of regulatory proteins such as cyclins, which are themselves regulated by proteolysis.
movement through the cell cycle is not controlled in the cells is True.
What regulates the movement of a cell through the cell cycle?In addition to this structural function, the cytoskeleton is in charge of cell movement. Internal transport of organelles and other structures (such as mitotic chromosomes) through the cytoplasm is one of these.Cell-cycle control is entirely dependent on post-transcriptional mechanisms such as phosphorylation of Cdk activity and the binding of regulatory proteins such as cyclins, which are themselves regulated by proteolysis.Disruption of normal cell cycle regulation can result in diseases such as cancer. When the cell cycle is uncontrolled, cells can divide haphazardly and accumulate genetic errors, which can result in a cancerous tumor.To learn more about : Cell cycle

What are identical twins?The term identical twins make reference to monozygotic twins, i.e., twins produced from the same zygote.
The zygote is a cell that generates during fertilization, i.e., by the fusion of a sperm cell and an egg cell.
The monozygotic twins have the same DNA because they were formed from the same sperm and egg cells.

What did the Aztecs do to keep the universe in motion?
Answer:
Abstract
Two oppositional, yet complementary, sets of myths are presented here. These sets appear based on a concept of transformation which implies that the cosmos will collapse if a paradigm of human sacrifice is not followed-a paradigm for moral action utilized by Aztec kings in an amoral universe requiring constant nourishment. Models of this paradigm are seen to shape ethical decisions in two different examples: (a) crises of drought, and (b) problems of childraising. It is suggested that this moral and ethical information is presented to us, in varied sources, as an ontological reality which was gained by the direct experiencing of rituals participated in from infancy to death.
Journal Information
Founded in 1973 to "assist in shaping and locating the advanced edge of scholarly work in religious ethics." The Journal of Religious Ethics is committed to publishing the very best scholarship in religious ethics, to fostering new work in neglected areas, and to stimulating exchange on significant issues. Neither a tradition-specific journal of social ethics nor a tradition-neutral journal of philosophical ethics, the JRE offers serious ethical reflection set in the context of specific religious traditions and communities. The journal seeks to publish essays in three domains: studies in comparative religious ethics, considerations of foundational conceptual and methodological issues, and historical studies of influential figures and texts. An independent scholarly journal, the JRE is currently edited at Florida State University.

Answer:
Urethra and vas deferens
Explanation:

The sense organs of a cat work together to enable them to respond quickly and appropriately to stimuli in its environment.
What are the sense organs in a cat?Cats have highly developed senses that enable them to respond quickly to stimuli in their environment.
The senses and sense organs in a cat are as follows:
Vision: Cats have excellent night vision and can see well in low light conditions. Their eyes have a tapetum lucidum, a reflective layer that enhances their vision in dim light. They have a large number of rods in their eyes which help them detect movement and light in low light conditions.Hearing: Cats have highly sensitive ears that can detect high-frequency sounds beyond the range of human hearing. They have 32 muscles in their ears which allow them to rotate their ears 180 degrees, helping them locate the source of the sound.Smell: A cat's sense of smell is highly developed, and they use it to identify prey, locate food, and recognize other cats. They have an olfactory epithelium in their noses which helps them detect scents that are not detectable by humans.Taste: Cats have fewer taste buds than humans, and their sense of taste is not as highly developed. However, they can distinguish between sweet, sour, salty, and bitter tastes.Touch: Cats have sensitive whiskers and highly sensitive paws that allow them to feel vibrations and textures. Their whiskers help them navigate in the dark and sense changes in their environment.In response to stimuli, cats will use their senses to assess the situation and determine their response. For example, if they detect a high-frequency sound, they may rotate their ears to locate the source of the sound and then determine whether it is a potential threat or not. If they smell a strange scent, they may become cautious or alert and investigate the source of the smell. If they see a moving object, they may use their highly developed sense of vision to assess whether it is prey or a potential threat.

In 1915, the scientist Thomas Hunt Morgan discovered that certain genes on chromosomes are associated with specific traits in fruit flies. However, the mechanism through which this process occurs was not detailed until 1966. That is when Marshall Nirenberg and several other scientists demonstrated that specific sequences of nucleotides in DNA correspond to specific proteins. After gene sequencing was introduced in 1977, scientists were able to use Nirenberg's discoveries to predict an organism's proteins from its DNA sequences.
How does the information above illustrate the nature of science?
A.
It shows that scientific progress is made primarily through observational rather than experimental evidence.
B.
It shows that earlier scientific ideas are typically incorrect since genes code for proteins and not traits.
C.
It shows that scientific ideas are durable but are developed as new data are collected.
D.
It shows that scientists like Nirenberg did not rely on ideas of others in making major discoveries.
