The examples of geological processes that occur slowly is soil erosion and weathering.
What do you mean by soil erosion?Soil erosion is the denudation or wearing away of the upper layer of soil. It is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice, snow, air, plants, and animals.
Soil erosion occurs primarily when dirt is left exposed to strong winds, hard rains, and flowing water. In some cases, human activities, especially farming and land clearing, leave soil vulnerable to erosion.
Removing trees and plants, plowing fields, and overgrazing by livestock disrupts roots that stabilize sediment and soil. These human activities can increase erosion rates 10 to 100 times that of non-human geologic processes.

draw neat and labelled diagram of smooth muscle?
Muscular system is an organ system, Body performs all the kind of movements with the help of muscular system. Almost all the animals have muscles. The muscular system is composed of specialized cells called muscle fibers. Their predominant function is contractibility. Muscles are attached to bones or internal organs and blood vessels. There are more than 600 muscles present in a human body.
[tex]\Large\textbf{Types of Muscles:}[/tex]
There are three types of muscles in a vertebrate body. They are
skeletal musclescardiac musclessmooth muscles[tex]\Huge\text{Smooth Muscles}[/tex]
Smooth muscles are structurally the simplest of all muscles types. They are non-striated, and consist of long spindle shaped uni-nucleated muscle cells that are usually arranged in sheets that surround the body's hollow organs. Smooth muscles are also involuntary in action. Smooth muscles push the food through the digestive tract, they empty your urinary bladder, they control the diameter of the blood vessels, the diameter of your eye, the state of erection of hair of the skin, and the smooth muscles form the layer of sheet around all the visceral organs.
Non-striated muscles, this means that muscles do not have transverse light and dark bands. The striations are caused by the regular arrangement of contractile proteins (actin and myosin). Actin is a globular contractile protein that interacts with myosin for muscle contraction. This means that non-striated muscles can not contract, thus they can not move.
Uni-nucleated Muscles, Smooth muscles are the only muscles which have cells with only one nuclei.
Involuntary in action, This means that their contraction is not under the control of somatic nervous system. The involuntary muscles are automatically controlled by the autonomic nervous system controls the activities of the inner visceral organs (heart, glands, smooth muscles), while the somatic nervous system controls all the voluntary actions.
Visceral Organs, word Visceral arises from latin word Viscera which means "the organ of the body", So Visceral organs are all the internal organs of the body, specifically those within the chest and abdomen. They are covered with visceral membrane made of smooth muscles.
I have attached two pictures of the smooth muscles, one is colored and the other one is colored and the other one is diagrammatic.

How can we tell histologically that skeletal muscle tissue is highly vascular?
Answer:Muscle tissue is composed of cells specialized for contraction. Muscle is classified into three types according to their structure and function:
Skeletal muscle cells - striated, voluntary control
Cardiac muscle cells - striated, involuntary control
Smooth muscle cells - nonstriated, involuntary control
Skeletal and cardiac muscle cells are called striated because they show an alternating series of bands. The repeating arrangement of their basic contractile unit, the sacromere, produces these striations.
In all types of muscle, contraction is caused by the movement of myosin filaments along actin filaments.
The terms muscle cell and muscle fiber are synonymous.

Which of the following characteristics of a population will make it better able to adapt to environmental changes?
A.Rapid production of many offspring.
B.Specialization in one type of food source.
C.Large amount of inherited genetic variation.
D.Isolation to a limited geographic range.
Answer:
C
Explanation:
Answer: C. Large amount of inherited genetic variation.
If you had a population where the genetic variation wasn't as high or practically non-existent, then that population is likely suited to that very narrow specific environment. If the environment doesn't change, then the population wouldn't have a problem. However, the environment isn't likely to stay static. Things change all the time and this change will bring challenges to the population that was suited for the old environmental conditions.
Populations with high genetic variability will have some individuals thrive while some unfortunate members will perish. The members that die off are likely the ones who cannot adapt to the changes. As the environment changes, the individuals who survive will pass on their DNA to their offspring, allowing for natural selection to reinforce those favorable traits. Since the environment is constantly changing, whether that change is slow or fast, this means the process is continued indefinitely. So that's why high genetic variability is favored.

Whats sounds can dogs hear that we cant ?
Answer/Explanation:
Dogs have outstanding senses. not only do they have good smelling sense but they also have a good sense of hearing. Humans can't hear hear above 20,000 HZ. However, dogs can hear much higher pitches than we can. Dogs can hear up to 65,000 HZ. This is why we are unable to hear a dogs whistle, but the dogs can.
If you need to drive from Dallas, Texas, to Salt Lake City, Utah, (about 1500 miles), and the speed limit is 60 mph most of the way, what is the least amount of time you will need?
Answer:
25 hours
Explanation:
Speed is a measure of the distance traveled by a body relative to the time taken to complete a trip or a journey. Mathematically, speed can be expressed as;
speed = distance/time
Hence, time = distance/speed
The distance covering Dallas, Texas, to Salt Lake City, Utah is about 1500 miles and the speed limit is 60 mph, hence;
time = 1500/60
= 25 hours
Therefore, the least amount of time that would be needed to cover the journey is 25 hours.
Answer:
25 hours is your answer

A man catches a disease. The man has not been immunised against this disease. A doctor gives the man a course of antibiotics. Figure 2 shows how the live number of live disease in the body changes when the man is taking the antibiotics. Four days after starting the course of antibiotics the man feels well again. It is important that the man does not stop taking the antibiotics .Explain why
Answer: To kill the bacteria causing the illness
Explanation:
When a person takes antibiotics, the bacteria causing diseases will be severely hampered in its operations which will lead to the symptoms of the disease reducing. The bacteria will not die until the drug is taken as prescribed which is why the full dosage must be taken.
If it is not, the bacteria can regain strength and start causing sickness again except this time, it may grow an immunity to the antibiotics which means that an even stronger dosage of antibiotics will be needed.
Which would be an autotroph in a grassland ecosystem
Answer:
prairie cordgrass
Explanation:
Spartina pectinata is a species of cordgrass known as prairie cordgrass, freshwater cordgrass, tall marshgrass, and sloughgrass. It is native to much of North America, including central and eastern Canada and most of the contiguous United States except for the southwestern and southeastern regions.
Autotrophic organisms may synthesize organic chemicals from inorganic substances like light prairie cordgrass is an autotroph in a grassland ecosystem, hence option B is correct.
What are autotrophs?Autotrophs are another name for producers. Through a process known as photosynthesis, they produce all of their own food.
Autotrophic organisms are producers because they have the ability to transform inorganic elements like light into the nourishment that best suits their requirements. The majority of these species are plants that photosynthesize.
1% of the energy that reaches the earth's surface is absorbed by autotrophs. From autotrophs to heterotrophs, this little fraction of energy passes through the entire ecosystem before dissipating in the environment.
Therefore, organisms may synthesize organic chemicals from inorganic substances like light prairie cordgrass is an autotroph in a grassland ecosystem, hence option B is correct.

Cross two heterozygous black mice and tell the possible phenotypes and
genotypes in their offspring.
Answer:
The correct answer is -
Phenotype: 3:1 (dominant black mice: recessive brown allele)
genotype: 1:2:1 (purebred dominant : heterozygous: purebred recessive)
Explanation:
In the given question there is a cross that takes place between two heterozygous black mice. LEt assumes B is black which is the dominant allele and b is the recessive allele or brown. As it is given in heterozygous condition black mice are present which means the B is dominant over b.
Now cross:
Gametes: B and b for each mice
B b
B BB Bb
b Bb bb
By the cross, there are two phenotypic offspring that produce 3 black mice out of four and 1 brown or recessive allele out of four
And, genotypically three offspring in the ratio of 1:2:1 (purebred dominant : heterozygous: purebred recessive)
What causes the "plastic" nature of
the asthenosphere?
A. it is mostly water
B. it only found under the ocean
C. constant earthquake activity
D. heat from below
The heat from below causes the "plastic" nature of the asthenosphere. The correct option is D.
What is asthenosphere?The asthenosphere is the upper mantle's mechanically sluggish and ductile region.
It is located beneath the lithosphere, somewhere around 80 and 200 kilometers underneath the surface, and can extend up to 700 kilometers. However, the asthenosphere's lower boundary is not well defined.
Semi-plastic rock makes up the Asthenosphere. Because of Lithosphere has a lower density, it resides on top of the Asthenosphere, much like an iceberg or a block of wood does on water.
The lower mantle beneath the Asthenosphere is stiffer and less plastic. The outer core is located beneath the Mantle.
The "plastic" essence of the asthenosphere is caused by heat from below.
Thus, the correct option is D.

Explanation:
A young man recently learned from a genetics doctor that he had a condition called Friedreich's ataxia. This syndrome affects the arms and the legs with the person usually needing a wheel chair. Neither of his parents have this disorder. However the young man's grandfather was wheelchair bound, but didn't know why because genetic information was very limited when his grandfather grew up. Based on this information, what type of inheritance does Friedreich's ataxia follow? Explain why. What are the genotypes of each of the individuals mentioned in this question? Create a pedigree chart to support your answer.
Answer: Friedreich ataxia is a genetic condition that affects the nervous system and causes movement problems. People with this condition develop impaired muscle coordination (ataxia) that worsens over time. Other features of this condition include the gradual loss of strength and sensation in the arms and legs; muscle stiffness (spasticity); and impaired speech, hearing, and vision. Individuals with Friedreich ataxia often have a form of heart disease called hypertrophic cardiomyopathy, which enlarges and weakens the heart muscle and can be life-threatening. Some affected individuals develop diabetes or an abnormal curvature of the spine (scoliosis).
Most people with Friedreich ataxia begin to experience the signs and symptoms of the disorder between ages 5 and 15. Poor coordination and balance are often the first noticeable features. Affected individuals typically require the use of a wheelchair about 10 years after signs and symptoms appear.
About 25 percent of people with Friedreich ataxia have an atypical form in which signs and symptoms begin after age 25. Affected individuals who develop Friedreich ataxia between ages 26 and 39 are considered to have late-onset Friedreich ataxia (LOFA). When the signs and symptoms begin after age 40 the condition is called very late-onset Friedreich ataxia (VLOFA). LOFA and VLOFA usually progress more slowly than typical Friedreich ataxia.
The genotype of the grandfather and the young man is ff (f allele for Friedreich's ataxia) The genotype of the father and the mother is Ff.
What is a genotype?A genotype is a classification of the type of variant found at a certain position (i.e., a locus) in the genome. Symbols can be used to symbolize it.
Friedreich ataxia is a hereditary disorder that causes movement issues by affecting the neurological system. This disorder causes decreased muscular coordination (ataxia), which worsens over time.
Individuals with Friedreich ataxia frequently have hypertrophic cardiomyopathy, a type of cardiac disease that enlarges and weakens the heart muscle and can be fatal. Some people who are impacted have diabetes or an irregular spine curvature (scoliosis).
Therefore, the genotype of the grandfather and the young man is ff (f allele for Friedreich's ataxia) The genotype of the father and the mother is Ff.
