Briefly describe how signals move through and between neurons.
Use the following terms in your description:
1. Neurons receive signals or inputs through their dendrites.
2. A signal then travels through the cell body of the neuron, and down through the axon.
3. The axon is surrounded by the myelin which acts as an insulator to help the signal move
through the neuron quickly.
4. Once the signal reaches the end of the axon, it needs to be passed to the dendrites of the
next neuron, which means it needs to travel through the gaps between two neurons
called the synapse.
5. Neurotransmitters help transfer a signal across they synapse and allows it to pass from
neuron to neuron.

The matching strands will be TAACGGTAAT.

In DNA base pairs of one strand in DNA bind with the base pairs of the other strand. A always pairs with T with two hydrogen bonds and G always pairs with C with three hydrogen bonds. So if one strand is ATTGCCATTA​then the complementary strand will be TAACGGTAAT.

Rules of base pairing are pairing will always be A with T the purine adenine (A) always pairs with the pyrimidine thymine (T) ,C with G the pyrimidine cytosine (C) always pairs with the purine guanine (G). In DNA two strands are always held together by hydrogen bonds between pairs of two bases adenine pairs with thymine, and cytosine pairs with guanine.

If a woman is a carrier for the color blind recessive allele and her husband is normal, the chances that their son will be color blind is 50%.

The female carrier of a color-blind recessive allele is represented by XBXb, while the normal husband is represented by XBY, where X represents a dominant allele for normal vision, Y represents a dominant allele for normal vision, and B represents a recessive allele for color blindness. The possible genotypes for the offspring are shown below:XBXB (normal daughter)XBXb (carrier daughter)XBY (normal son)XbY (color blind son)Each offspring's genotype is determined by which allele they inherit from each parent. Because males only inherit one X chromosome from their mother, if they inherit the Xb allele, they will be color blind. As a result, a woman who is a carrier of a color-blind allele has a 50% chance of producing a color-blind son when she mates with a normal male, such as XBY.

High resistance to muscle fatigue, more reliant on oxidative metabolism and large Triglyceride stores are type i muscle fibers. Low Mitochondrial density, large glycogen stores and more reliant on glycolytic metabolism are type ii muscle fibers.

Myofibrils are the building blocks of muscle fibres. The basic functional, contractile units of the muscle fibre required for muscular contraction are found in the myofibrils, which are made of actin and myosin filaments known as myofilaments and repeated in units known as sarcomeres. The oxidation of lipids and carbohydrates provides the majority of the energy for muscles, although anaerobic chemical processes are also utilized, especially by quick twitch fibers.

Adenosine triphosphate (ATP) molecules are created as a result of these chemical processes and are utilised to drive the motion of the myosin heads. Multiple fascicles are bundles of muscular fibres found inside skeletal muscles.

On slide B, the red blood cells appear to have undergone a change in shape and structure. The red blood cells on slide B are exhibiting a characteristic known as sickle cell morphology.

Sickle cell morphology refers to the abnormal, crescent or sickle-like shape assumed by red blood cells affected by sickle cell disease. This genetic disorder causes the production of abnormal hemoglobin, known as hemoglobin S, which leads to the distorted shape of red blood cells.

In individuals with sickle cell disease, the hemoglobin S molecules tend to stick together, forming long, rod-like structures within the red blood cells when oxygen levels are low or during periods of stress. These abnormal hemoglobin molecules cause the red blood cells to become rigid and lose their normal biconcave shape. Instead, they develop a crescent or sickle-like appearance.

The altered shape of the red blood cells in sickle cell disease has significant implications for their functionality. The sickle-shaped cells are less flexible and have a reduced ability to carry oxygen efficiently. Additionally, their abnormal shape makes them more prone to getting stuck in small blood vessels, causing blockages and impairing blood flow. This can result in episodes of intense pain, tissue damage, and organ dysfunction.

In conclusion, the red blood cells on slide B are displaying sickle cell morphology, indicating the presence of sickle cell disease. The abnormal shape of these cells compromises their oxygen-carrying capacity and increases the risk of blockages within the blood vessels, leading to various health complications associated with sickle cell disease.

Answer:

A period happens because of changes in hormones in the frame. Hormones are chemical messengers. The ovaries launch the lady hormones estrogen and progesterone . those hormones motive the liner of the uterus (or womb) to build up. The constructed-up lining is prepared for a fertilized egg to connect to and begin developing. If there is no fertilized egg, the liner breaks down and bleeds. Then the identical manner occurs all once more.

It normally takes about a month for the liner to build up, then smash down. this is why a lot of ladies and women get their periods round once a month.

Explanation:

If a pigeon homozygous for the grouse allele mates with a heterozygous pigeon, the expected frequency of the feathery-legged (grouse) phenotype in the offspring will be 0%. The correct answer is A.

If a pigeon is homozygous for the no grouse allele, it means that it carries two copies of the dominant allele, which masks the expression of the recessive grouse allele.

On the other hand, a heterozygous pigeon has one copy of the no grouse allele and one copy of the grouse allele.

In this case, the no grouse allele is still dominant and masks the expression of the grouse allele, but the grouse allele can be passed on to its offspring.

Therefore, when a homozygous pigeon for the no grouse allele (NN) mates with a heterozygous pigeon (Nn), all offspring will inherit one copy of the no grouse allele from the homozygous parent and one copy of either the no grouse or the grouse allele from the heterozygous parent.

The possible genotypes and their corresponding phenotypes are as follows:

   NN (no grouse allele) = no grouse phenotype

   Nn (no grouse allele) = no grouse phenotype

   Nn (grouse allele) = no grouse phenotype

   nn (grouse allele) = grouse phenotype

Since the no grouse allele is dominant, all offspring with at least one copy of this allele will exhibit the no grouse phenotype.

Therefore, the expected frequency of the feathery-legged (grouse) phenotype in the offspring is 0%, and the correct answer is A) 0%.

Elastic connective tissue is a type of connective tissue that provides support and elasticity to various tissues and organs in the body. It is composed of long, flexible, and elastic fibers known as elastin

explain about elastic connective tissue ?

Elastic connective tissue is found in many different structures in the body, including the walls of large arteries, the bronchial tubes in the lungs, the walls of the vocal cords, and the skin. Its elasticity allows these structures to stretch and then return to their original shape, which is important for their proper functioning.

For example, in the walls of large arteries, the elasticity of the elastic connective tissue allows the blood vessels to dilate and contract with each heartbeat, which helps to regulate blood flow and blood pressure. In the lungs, the elasticity of the bronchial tubes helps to regulate air flow and volume during breathing. And in the skin, the elastic connective tissue helps to maintain skin's resilience and elasticity, preventing it from becoming saggy or wrinkled.

Quantum mottle term is used to describe image noise caused by an insufficient number of x-ray photons interacting with a digital image receptor.

A sort of radiographic noise known as quantum mottle is inversely proportional to the number of x-ray photons that leave the patient and create the radiographic image. Images will appear gritty or sandlike if there are fewer photons that reach the image receptor, causing an unfavorable fluctuation in picture densities.Due to a mistake in the predetermined exposure settings, quantum mottle noise is caused by an ineffective number of photons reaching the imaging plate (mAs and kVp). This may result in a grainy image, which can be easily fixed by modifying the mAs or kVp, depending on which is more appropriate for the clinical situation.

Although both hawks and owls have two sources of food, hawks are less likely to survive if a disease wiped out the mice. Hawks require more than 100 calories per day, while owls need about 50 calories.

As a result, hawks would require more food than owls to meet their dietary needs. Since hawks consume smaller prey like mice, a reduction in the mouse population due to a disease would adversely affect the hawks' survival chances.It is because hawks require more than 100 calories per day, while owls only require about 50 calories. As a result, hawks would need more food than owls to meet their dietary needs. Hawks consume smaller prey like mice, so a decrease in the mouse population due to a disease would adversely affect the hawks' survival chances.
