Tortoise shell cats, like the one shown above, are always femaleWhat scientific phenomenon explains the color pattern of
Tortoise shell cats can be explained as the offspring from a incomplete dominance cross. Incomplete dominance gives rise to an intermediate phenotype.
The scientific phenomenon that explains the color pattern is X-linked incomplete dominance.
As stated earlier, the tortoise shell colour is as a result of incomplete dominance but as it exists only in females, the inheritance is X linked. This means the tortoise shell colour is inherited in the heterozygous condition as females have two X (XX) and males (XY) can only be either of the parent's true breeding genotype.Learn more about X- linked traits: https://brainly.com/question/14548821
When a dark blue fish and a light blue fish with dark blue fins were mated , all offspring became dark blue. What could also be seen was that part of the offspring got light gray fins.Explain with the help of genetics why all fish turn dark blue.
Answer:
The allele for dark blue fish must be dominant and the dark blue parent fish must be homo-zygous dominant;
This would mean the dominant allele would necessarily be inherited by all offspring and since it is dominant, it would be expressed over the other allele (light blue fish)
The Diagram shows structures that form the surface of the trachea.
Which level of organisation is the structure labelled S ?
A. Cell
B. Organ
C. Organ system
D. Tissue
Structure S is a simple columnar epithelium, which is a type of tissue.
The diagram shows the structures that form the surface of the trachea. The trachea is a tube that carries air from the lungs. The surface of the trachea is lined with a layer of tissue called the epithelium. The epithelium is made up of cells that line the inside of the trachea.
The structure labelled S is a type of epithelium called a simple columnar epithelium. Simple columnar epithelia are made up of cells that are arranged in a single layer. The cells in a simple columnar epithelium are tall and column-shaped.
The simple columnar epithelium in the trachea helps to protect the trachea from infection. The cells in the epithelium produce a mucus that traps dust and other particles. The mucus is then carried away by the cilia, which are tiny hairs that line the trachea.
The other levels of organization in the diagram are organ, organ system, and cell. The trachea is an organ, which is a collection of tissues that work together to perform a specific function. The respiratory system is an organ system, which is a group of organs that work together to perform a common function. Cells are the basic units of life, and they are the building blocks of tissues, organs, and organ systems.

What is the relaxed form of dna in a cells nucleus?
Answer:
The relaxed form of DNA that can be found in the nucleus is referred to as chromatin. This form of DNA is observed when the cell is not dividing.
Explanation:
hope this helps
The relaxed form of DNA in a cell's nucleus is called chromatin.
CHROMATIN:Chromatin is a complex of DNA and histone proteins within the cell's nucleus. The DNA is too long to fit into the cell's nucleus, hence, is coiled around proteins called histones. This complex forms the structure called chromatin, which then condenses during the prophase stage of cell division to form a more compact structure called chromosome.Therefore, it can be said that the relaxed or uncondensed form of DNA in the nucleus of a cell is called chromatin.

A drought is a long period of abnormally low precipitation. Suppose a drought occurred in Yellowstone National Park from 1916 to 1917. Predict how a graph line would appear for this time period. Explain your prediction in terms of the effect on resource availability.
Answer:
A drought is a long period of abnormally low precipitation. Suppose a drought occurred in Yellowstone National Park from 1916 to 1917. Predict how a graph line would appear for this time period. Explain your prediction in terms of the effect on resource availability.
Explanation: The graph line would have a downward trend because the amount of bison would start to decrease. Droughts heavily impact grassland ecosystems. A drought would increase the risk of a wildfire starting causing the bison to lose their habitat. The drought would also result in reduced plant growth. Therefore the bison would die off either because they were impacted by a wildfire, because they don’t have grass to eat etc.

[tex]\large\huge\green{\sf{Answer:-}}[/tex]
When white blood cells are unable to function correctly, the body is less able to fight bacteria and close wounds. People with uncontrolled diabetes may develop poor circulation. As circulation slows down, blood moves more slowly, which makes it more difficult for the body to deliver nutrients to wounds.

drag the labels to their appropriate locations on the diagram of the neurons below. use targets of group 1 to indicate the components of neurons. use targets of group 2 to indicate the locations of gated ion channels.
Neurons are cells in chauge of synapsis. a)cell body / b)myelin sheath / c)synaptic terminal / d)axon hillock / e)nucleus / f)location of voltage-gated channels / g)location of ligans-gated channels / h)axon / i)dendrite
-------------------------------
Most neurons are composed of a cell body, dendrites that are cytoplasmic extensions that receive impulses from other cells, and an axon that is a long formation capable of conducting the electrochemical signals.
Neurons transmit nervous impulses.
Every neuron forms connections with other neurons. These connections are known as synapsis.
During synapsis, when a presynaptic neuron sends information, it releases neurotransmitters. This event is done through exocytosis.
The neurotransmitter is a molecule that travels through the synaptic space forward to the other neuron.
Once it reaches the target, it binds to its receptors in the postsynaptic membrane, causing ion channels to open.
This binding produces a depolarization of the cell called an excitatory postsynaptic potential.
Once the action potential is initiated, it spreads to the rest of the membrane, depolarizing it.
When the electrical stimulus is applied to the axon's membrane, it produces depolarization by activating the sodium voltage-dependent channels all along the axon.
Besides, there is an increase in sodium permeability.
Depolarization propagates to inactivated regions adjacent to the membrane opening more sodium channels.
The fiber diameter and the conduction velocity are closely related, exhibiting a directly proportional relationship. Mielinized fibers are thick, and their conduction velocities are very fast.
The conduction velocity sharply increases in myelinated fibers. This is because of the high concentrations of sodium channels in the Ranvier nodes that are not myelinated areas, and the diameter of the axon becomes thinner.
