in the family the father is affected by a genetic disorder the son in the family has the same disease but the daughters do not have it. what type of inheritance is this ?
Answer:
Explanation:When a genetic disorder is diagnosed in a family, family members often want to know the likelihood that they or their children will develop the condition. This can be difficult to predict in some cases because many factors influence a person's chances of developing a genetic condition. One important factor is how the condition is inherited.

in phantom limb syndrome, which sensory pathway is responsible for conveying the sensory neuron activities?
The experience of the phantom limb syndrome involves the subjective sensation of the patient, the processes involved in this sensation are: both sensitive activity and the motor pathway.
The somatic nervous system is made up of mixed nerves (mixtures of sensory and motor axons) that emerge from the central nervous system, innervate the somatic effectors (skeletal muscles).Somatic motor pathways begin in the motor areas of the cerebral cortex, the projection neurons in that cortex emit axons that descend through the brain stem until they reach the spinal cord.Patients with this syndrome experience the sensation that the amputated limb is still attached to their body, since the brain continues to receive messages from the nerves that originally carried the impulses from the lost limb.Therefore, we can conclude that Phantom Limb Syndrome is the perception of sensations, which include pain of an amputated limb, where both sensory activity and the motor pathway have an action on said sensations.

What is the role of ATP in transport of materials
Answer:
Functions of ATP in cells
Explanation:
ATP plays a critical role in the transport of macromolecules such as proteins and lipids into and out of the cell. The hydrolysis of ATP provides the required energy for active transport mechanisms to carry such molecules across a concentration gradient.
Answer:
The role of ATP in the transport of materials :- To move substances against a concentration or electrochemical gradient, the cell must utilize energy in the form of ATP during active transport. Primary active transport, which is directly dependent on ATP, moves ions across a membrane and creates a difference in charge across that membrane.Explanation:

What does an alcoholic beverage contain that is a central nervous system depressant? 
Answer:
interferes with release of neural transmitter GABA
Explanation:
Alcohol is a central nervous system depressant, meaning it slows down brain functioning and neural activity. Alcohol does this by enhancing the effects of the neural transmitter GABA
depressants essentially "look" like the neural transmitter and so they go in and block the plasce in the brain between synapses, so when the body tries to release GABA, it appears as if it is already filled in, but in reality it is the alcohol that has filled it. once they start buidling up, they block enough that it impairs brain activity
Answer:
GABA
Explanation:
gamma-aminobutyric acid (GABA)

Outline what has to occur in the body for a reflex and a voluntary action to occur.
Answer:
For involuntary actions (reflexes) the information is first detected in the sensor and travels along sensory neurons to the spinal cord. Once the action potential reaches the spinal cord, the information is transmitted across the synapse to the motor neuron. for voluntary actions,
movements are commanded by the motor cortex, the zone of the cerebrum located behind the frontal lobe. The motor cortex sends a neural message that moves through the brain stem along the spinal cord and into the neural network to the muscle being commanded.

Briefly summarize the structure of moss.
Mosses are bryophytes, primitive plants believed to be among the first to develop the ability to live on land. Moss plants have no vascular tubes to transfer water or nutrients, and no true stems or roots. Environmental water sources and absorption limit moss plant size.
There may be as many as 15,000 species of mosses. Although unique species of moss grow in dramatically different habitats across the planet – from the arctic to the desert – all have basically the same structure.
Basic Moss SporesThe initial moss plant is a spore given off by the sporophyte that forms at the end of the moss plant’s “stem.” Released spores travel long distances on the wind and may remain viable for decades. Moss spores landing in suitable conditions divide and produce hairy filaments called protonemas, which are like thin plant threads that weave across the growing medium. Sprouting from the spore filaments, gametophytes form, held to the surface by rhizoids.
Main Structure of MossThe main moss structure is the gametophyte, which functions like a moss’s “stem” and “leaves.” A moss "stem" is called the axis, and this part of the moss supports leaf-like structures.
Phyllids are the leaf-like structures that carry out photosynthesis, transforming sunlight into sugars the moss uses for food. Typically arranged in a spiral, moss “leaves” are usually one cell thick with ribs two or more cells thick down their centers. The cells of moss plants contain chlorophyll, the green pigment that is essential for the process of photosynthesis.
Does moss have roots? No, not really. Moss stems end in root-like strands called rhizoids, specialized to hold the moss to its growing surface. Rhizoids anchor moss plants to the surfaces they grow on, but they do not absorb water and nutrients like true plant roots.
Second-Generation GrowthThe second moss structure is really a second generation. Moss reproduction occurs sexually, using separate plants produced at different times. The two separate kinds of moss plants are called gametophytes (which produce gametes) and sporophytes (which produce spores).
Gametophytes are tipped with either inverted cone-shaped areas (archegonia) or male reproductive organs (antheridia). Released sperm (antherizoids) need water since they swim to the archegonium. This is one of the main differences between bryophytes and vascular land plants – mosses need water for their sexual reproduction process.
Fertilization occurs once an antherizoid swims to an archegonium. Sprouting from the gametophyte tip after fertilization, a sporophyte holds itself in place by anchoring a foot in the archegonium.
Spore-Bearing PartsThe sporophyte stalk, called the seta, bears the sporangium (spore capsule) on its tip. One sporangium may produce up to one million spores. Maturing spore capsules are guarded by a covering called the calyptra that shrivels and falls off when the spores are mature. The calyptra can be a distinguishing part of a moss species, and they are often useful in identifying new mosses.
A cap called the operculum tops the capsule's opening under the calyptra. The capsule opening (peristome) can have teeth that help hold it closed. Matured spores are released when the capsule top ruptures and drift off to form new plants. Like the calyptra, the operculum and peristome of some moss species are highly identifiable.
Sexual reproduction in animals depends on the production of gametes. Which of these processes produces gametes in animals?
