an impulse from the brain to the knee joint will travel on ___________ neuron.

Answers

An impulse from the brain to the knee joint will travel on a motor neuron.

Motor neurons are a type of nerve cell that carry signals from the central nervous system (brain and spinal cord) to muscles, organs, and glands, allowing for movement and other bodily functions. The motor neuron responsible for transmitting the impulse to the knee joint is part of the somatic nervous system, which controls voluntary movements and reflexes.

The impulse travels down the motor neuron, triggering the release of neurotransmitters that signal the knee muscles to contract or relax, resulting in movement or stabilization of the joint. It is important to note that the speed at which the impulse travels on the motor neuron can be affected by factors such as nerve damage, disease, and injury. So therefore an impulse from the brain to the knee joint will travel on a motor neuron.

Please list 15 facts about Black Jaguars.
At least 10 facts will be helpful.
I will give brainliest to whoever lists 10-15 facts.

Answers

The jaguar is a big cat in the Panthera genus, the jaguar's scientific name is Panthera onca.

The jaguar is the 3rd largest of the big cats after the tiger and the lion and it is the largest of all the big cats in the Americas.

Jaguar's are only found in the Americas. Their range extends from Arizona in South-west United States, Mexico, through Central America, into most Amazon River Basin countries in South America and as far south as northern Argentina.

The jaguar's preferred habitat is dense rainforest, but they are also found across other forested areas and open plains.

With its spotted coat the jaguar most closely resembles the leopard which is found in Asia and Africa, however, the jaguar is larger and has a stockier build than the leopard, it also has less but bigger rosettes (spots) with small dots in the middle. While the jaguars behavioural habits more resemble that of a tiger.

Like the tiger, jaguars enjoy water and are good at swimming.

Jaguars roam, hunt and live alone, only coming together to mate. They leave a scent to mark their territory. Female territories may overlap and range in size from 25 - 40 km2. While males territories are double that size, a male will aggressively protect his area (and the resident females within it) from other males.

The jaguar stalks and ambushes its prey, often leaping into water or from a tree.

Jaguars are carnivores, they prey on over 80 species of animal of all sizes, such as deer, pigs, capybara, foxes, fish, frogs and even large anaconda snakes.

The jaguar has a very powerful jaw, its bite exerts more force than that of a lion.

Male jaguars are about 10-20% larger than females. On average jaguars weigh between 124 - 211 lbs (56–96 kg) and are 4 ft to 6.5 ft (1.2 to 1.95 m) in length.

Jaguars live in the wild for 11-15 years, in captivity they can live over 20 years.

Many ancient American cultures such as the Maya and Aztec, featured the jaguar in their mythologies, it was often regarded as a symbol of strength.

Argentina's national rugby team badge includes a jaguar. However, a historical error resulted in the team being nicknamed to this day, Los Pumas (the pumas).

Answers

Given the diagrams attached in the question, we can conclude that Ciara is correct in her prediction of the lunar cycle.

Ciara is correct in her prediction given that if the moon should be in this position, on the far side of the earth in relation to the sun, it would appear, when viewed from earth, to be completely dark. The reason behind this is that the moon does not have an internal light source. What this means is that the moon, much like the earth and unlike the sun, cannot generate light on its own.

Therefore, the light that we see when looking at the moon from the Earth is actually just reflected sunlight bouncing off the surface of the moon. The diagram shows that the moon is on the far side of the Earth in relation to the sun, meaning that in this case, the Earth would block most if not all of the light from reaching the moon, giving it a dark appearance.

List the accessory organs of the digestive system and explain why they are called accessory

Answers

The salivary glands, liver and gall bladder, and the pancreas aid the processes of ingestion, digestion, and absorption. These accessory organs of digestion play key roles in the digestive process. Each of these organs either secretes or stores substances that pass through ducts into the alimentary canal.

Accessory organs are those that provide mechanical and chemical assistance in the process of digestion, the main organs are those where digestion actually occurs.
Explanation:
If you think of the digestive tract for what it is, it's a hollow tube that starts at the mouth and ends at the anus. It becomes not only rather amusing to think about, but it also helps to discern what is classed as a 'main organ', and what is classed as an 'accessory organ'.
First, we put food into our mouth where it is chewed and manipulated into manageable portions with our teeth and tongue, and also begins to get broken down by enzymes in our saliva; produced in the salivary glands . Here, the teeth, tongue and salivary glands are acting as accessories to digestion.
The food is then swallowed, where it travels down through the oesophagus before entering the stomach. These are both main organs. Whilst in the stomach, gastric juices break down the food and it is thoroughly churned up; it's worth noting that the stomach absorbs very few of the nutrients from food.
Once the stomach has done its work, the food is released into the small intestine, one of the main digestive organs, which is divided into three main parts. The first portion, the duodenum receives the food, and the liver/gall-bladder and pancreas act as accessory organs by secreting a range of enzymes directly into the duodenum via a series of ducts so that food can be further digested and broken down.
When this has been achieved, the waste begins to move into the jejunum, the second part of the small intestine, where nutrients are absorbed from the digested slurry. From there, it moves into the last portion of the small intestine, ileum, where any remaining nutrients are removed from the waste before it passes into the final main organ, the large intestine. Almost all nutrition has been absorbed by this point, so the primary purpose of the large intestine is to reabsorb as much of the water as it can from the waste.
The first portion of the large intestine is known as the caecum, and it is to this that the appendix protrudes. From there, it moves upwards via the ascending colon, until it reaches a bend that transitions into the transverse colon; which moves the waste across the abdomen before it hits the next bend, where the it becomes the descending colon. From here the now solid matter moves through the sigmoid colon, and into the rectum where it is free to be expelled as faeces, or poop.
To summarize this process:
The accessory organs are teeth, tongue, salivary glands, the pancreas and the liver/gall-bladder.
The main organs are the mouth, oesophagus, stomach, small intestine (duodenum, jejunum and ileum), and the large intestine (caecum, ascending colon, transverse colon, descending colon, sigmoid colon and rectum), and anus.

Tina is studying chipmunks in a field of 900 square meters. In 2020, she counts 194 chipmunks. In 2021, she counts 231 chipmunks. What is the population density of chipmunks in 2021?

Answers

Answer:the population density of chipmunks in 2021=256,666.667 per square kilometres

Explanation:

Population density is defined as the number of population per unit area of land

which can be expressed as

Population density =number of population/ land area

Since  land area is usually given in square kilometres or square miles  we convert 900 square meters to square kilometres

1 square kilometres =1000000 square meters

900 square meters=900/1000000=0.0009 square kilometres

Therefore, the population density of chipmunks in 2021= 231/0.0009 square kilometres =256,666.667 per square kilometres

A hereditary disorder, also known as a genetic disorder or genetic disease, is a condition that is caused by abnormalities or mutations in genes inherited from parents.

The down syndrome involves the presence of an additional copy of genes located on chromosome 21 rather than specific mutations in individual genes.

In Fragile X syndrome, the FMR1 gene on the X chromosome undergoes an expansion of CGG repeats, which leads to the inactivation or reduced production of the FMR1 protein. This mutation affects protein synthesis and neuronal development, resulting in the cognitive impairments and developmental delays observed in Fragile X syndrome.

Which statement describes the genes within DNA?

What are Supplementary and complementary genes, explain with example.

Answers

Supplementary and complementary genes are two concepts related to gene interactions and inheritance patterns.

1. Supplementary Genes:

Supplementary genes refer to a pair of genes that are located on different chromosomes and work together to produce a specific trait. Each gene in the pair independently contributes to the expression of the trait, and the presence of both genes is required for the full expression of the trait. When either one or both of the genes are absent, the trait will not be fully expressed.

An example of supplementary genes can be seen in the flower color of sweet peas. Let's say there are two genes involved: Gene A and Gene B. Gene A controls the production of pigment for blue flowers, and Gene B controls the production of pigment for red flowers. Only when both Gene A and Gene B are present in the plant, the flowers will show a full expression of color, resulting in purple flowers. If either Gene A or Gene B is absent, the flowers will be either blue or red, respectively.

2. Complementary Genes:

Complementary genes refer to a pair of genes that are located on the same chromosome and work together to produce a specific trait. However, unlike supplementary genes, the presence of both genes is not necessary for the trait to be expressed. Each gene in the pair independently contributes to the expression of the trait, but if both genes are present, they complement each other, resulting in an enhanced or more pronounced expression of the trait.

An example of complementary genes can be seen in the coat color of some animals, such as Labrador Retrievers. Let's say there are two genes involved: Gene C and Gene D. Gene C controls the production of pigment for black coat color, and Gene D controls the production of pigment for brown coat color. If an individual carries two copies of Gene C, it will have a black coat. If an individual carries two copies of Gene D, it will have a brown coat. However, if the individual carries one copy of each gene (Gene C and Gene D), the genes complement each other, resulting in a unique coat color known as "chocolate," which is a more pronounced expression compared to having just one gene.

In summary, supplementary genes require the presence of both genes for full expression of the trait, while complementary genes enhance or modify the expression of the trait when both genes are present.

The common hepatic duct is responsible for draining bile from the liver, which is produced by the hepatocytes. It is formed by the convergence of the right and left hepatic ducts, which drain bile from the corresponding lobes of the liver. The cystic duct, on the other hand, connects the gallbladder to the common bile duct and allows bile to flow from the gallbladder into the common bile duct. Together, these two ducts form the common bile duct, which carries bile to the small intestine, where it helps with the digestion and absorption of fats.

A population culture begins with 15 strands of bacteria and then doubles every 4 hours. This can be modeled as 15(2)^((t)/(4)), where t is time in hours. How many strands of bacteria are present at 12

Answers

At 12 hours, there are 120 strands of bacteria present.

The population of bacteria can be modeled using the equation P(t) = \(15(2)^(t/4)\), where P(t) represents the number of strands of bacteria at time t in hours.

To find the number of strands of bacteria at 12 hours, we substitute t = 12 into the equation:

P(12) = \(15(2)^(12/4)\)

P(12) = \(15(2)^3\)

P(12) = 15(8)

P(12) = 120

Therefore, at 12 hours, there are 120 strands of bacteria present.

It's important to note that the given population model assumes exponential growth, where the number of strands doubles every 4 hours. Starting with an initial population of 15 strands, the exponent in the equation (t/4) represents the number of doubling periods that have occurred. Each doubling period corresponds to 4 hours of time.

In this case, at 12 hours, three doubling periods have occurred (12/4 = 3). Starting with the initial 15 strands, each doubling period doubles the population, resulting in a final count of 15 * \(2^3\) = 120 strands of bacteria at 12 hours.
