Answer:
A. Dominant only
Explanation:
A dominant allele needs to be present in only one gene (so in the gene Qq, only Q would be present)
However, in order for a recessive allele to be present, it needs to have two genes (so in the gene qq, the recessive gene would be present)
once a neurotransmitter has done its job it is pulled back into the terminal buttons. this process is termed:
Neurotransmitters can either be deactivated by enzymes or reuptake, a type of chemical recycling, can reabsorb them from the terminal button.
What occurs once a neurotransmitter has completed its task?After finishing its task, a neurotransmitter can either be destroyed or reabsorbed. After serving as a chemical messenger, a neurotransmitter is either eliminated by an enzyme like monoamine oxidase or it is reabsorbed by the neuron that produced it, as Julius Axelrod discovered.
The process of a neurotransmitter being reabsorbed by the terminal button is known as?Once a neurotransmitter has completed its job of conveying a neuronal impulse, it is reabsorb able by a neurotransmitter transporter found along the plasma membrane of an axon terminal or glial cell.

when viruses are exposed to compounds or uv-light which make them non-infectious what are they called?
when viruses are exposed to compounds or UV light which makes them non-infectious are they called Inactive.
All virus particles have a protein coat that surrounds and protects their nucleic acid genome. This protein envelope is called a capsid, and the instructions for making the protein subunits of the capsid are encoded in the viral nucleic acid genome. Infections are caused by microscopic bacteria that enter the body and cause problems.
Some but not all infections are transmitted directly from person to person. Infections that are transmitted from person to person are considered contagious. Antibiotic resistance occurs when bacteria viruses fungi and parasites change over time and become unresponsive to drugs. This makes infections more difficult to treat and increases the risk of disease spreading serious illness and death.

Our autonomous vehicles will be trained to steer clear of crashes, particularly with people. However, what if a woman with a stroller suddenly jumps out into the road and the automobile does not have time to stop? The auto industry is well aware of all these ethical concerns, which is why Daimler, the owner of Mercedes-Benz, is hosting the first-ever conference on "Autonomous Driving, Law, and Ethics" this fall and manufacturers are consulting philosophers and ethicists.

a cell acquires a new mutation that raises its immediate direct fitness but lowers the inclusive fitness it will have later. will there be natural selection for the new mutation or against it when it first appears? group of answer choices
When a mutation first appears, the selection would occur against it as it lowers the inclusive fitness.
A technique for gauging the effectiveness of evolution is inclusive fitness. It is the capacity of an individual to pass on genes, including those shared with relatives, to the following generation.
However, advantageous mutations will proliferate and boost the population's overall fitness. They produce unique protein variations that help organisms adapt to changes in their environment. Most of the time, natural selection boosts evolutionary fitness and causes organisms to adapt to their environments. Thus, in this case the selection would be against the mutation.
Positive mutations are essential for evolution to occur. They increase an organism's likelihood of surviving or procreating, so they are likely to spread over time and become more widespread.

The device of cross-reactivity was previously believed to be related to a common β-lactam ring, but new evidence suggests it is instead related to the split of identical R-group side chains. Penicillin and cephalosporins exhibit limited and incomplete cross-reactivity of up to 7% which may be related to the 'cohort' of cephalosporin. 1 In clinical practice it is not uncommon for cephalosporins to be given to penicillin-allergic patients, especially if the history of penicillin reaction was not life.

Blood pressure, breathing, heart rate, and sweating all drop as digestion increases.
The hormone acetylcholine is released by the parasympathetic nervous (PNS) to slow the heart rate. Your heart rate may briefly increase due to stress, coffee, and excitement, but it may momentarily decrease due to meditation or deep, steady breathing. Patients with hypertension exhibit decreased parasympathetic activity in contrast to sympathetic stimulation activity, indicating an imbalance between the sympathetic and parasympathetic nervous systems [39,40,41]. In diabetic individuals with impaired parasympathetic regulation, blood pressure, hypertension is more common.

On the ventral surface of the brain, you can observe the optic nerves and chiasma, the pituitary gland, and the mammillary bodies. These externally visible structures form the floor of the Diencephalon
"Diencephalon" is the term used to describe the structures around the 3rd ventricle and form the nucleus of the cerebrum "big brain", the members of the diencephalon are the thalamus, hypothalamus, subthalamus and epithalamus.
Diencephalon Function
The diencephalon plays a role in the motor control of sensory information exchange and the control of autonomic functions of various parts of the body. Examples of some activities that involve the work of the diencephalon are chewing, seeing, eye movements, facial expressions, hearing, breathing, swallowing, smelling and regulating body balance.
Structure and Parts of the Diencephalon
Diencephalon consists of 4 structures that have their respective specific tasks, namely:
1. Thalamus
The thalamus is a structure located in the middle of the brain, precisely between the cerebral cortex and the midbrain. The word thalamus comes from the Greek word which means inner space. The main function of this gland is to convey sensory and motor signals related to consciousness, sleep and alertness to the brain cortex, the thalamus is a suborgan of the diencephalon.
2. Hypothalamus
The hypothalamus is the part of the brain that is the control center of the autonomic system, the hypothalamus is located just above the brainstem. This gland-shaped organ is part of the endocrine system. In humans, the hypothalamus is about the size of a pea and accounts for 1% of the total brain weight.
3. Subthalamus
The subthalamus is an important extrapyramidal motor nucleus that has many connections with other nervous system nuclei. The function of the subthalamus is not yet fully understood, but if there is an abnormality in this part, there will be abnormalities in the movement of the foot or hand that hit strongly on one side of the body.

During volume changes in the thoracic cavity, the diaphragm is primarily responsible for changes in length.

The diaphragm relaxes and assumes its dome-like form during exhalation, forcing air from the lungs. This implies that when the volume of the thoracic cavity changes during inhalation and exhalation, the diaphragm plays a vital role in length.
