The scientist who formulated the three laws of planetary motion by analyzing the data on the precise location of planets in the sky was: Johannes Kepler
What was the finding of Johann Kepler?German mathematician and astronomer Johannes Kepler made the discovery that the Earth and planets had elliptical orbits around the sun. He listed the three guiding principles of planetary motion.
Planets circle the sun in an elliptical pattern, which is explained by Kepler's first rule, sometimes known as the law of ellipses. A pencil, two tacks, a rope, a sheet of paper, and a piece of cardboard may all be used to create an ellipse.
According to Kepler's second rule, a planet travels in its orbit so that a line drawn between it and the Sun and focused on it covers the same amount of space in the same amount of time.

C- Extinct
D- Hungry
I think A or C
Explanation:
It really depends on how the question is phrased. Animals and plants that are unable to adapt to their enviroment will become- Hold it right there. How long will they be unadaptable? Is this forever? If so then yes, they will definately become extinct. If this is for a short amount of time then no, they will become prey, but there is also the fact that yes, they will become hungry. Because if they are not adapted then how are they gonna know the best sports for grub? Same thing for plants, if they can't adapt to the climate, they cannot produce food for themselves. Basically, if its a simple question then forget about everything else. It's Prey, because animals that can't adapt to their enviroment are immedietly in danger. Now if this question has more to it then I would go for C. But overall Just go with prey for now.
cup-shaped depression formed by all three portions of the hip (coxal) bone fill the blank
The cup-shaped depression formed by all three portions of the hip (coxal) bone is known as the acetabulum.
The hip (coxal) bone, also known as the pelvic bone, is a large, flat bone in the lower part of the body that connects the spine to the femur. The hip bone consists of three sections: the ilium, the ischium, and the pubis. The three parts meet to create a bowl-like shape known as the acetabulum. The acetabulum is a cup-shaped depression formed by all three portions of the hip (coxal) bone. It is the socket that the femur, or thigh bone, fits into to create the hip joint. The acetabulum is a crucial part of the skeletal system since it allows for hip movement and weight-bearing, which are necessary for walking and other activities.
Ilium, ischium, and pubis, their three component parts, are distinct in young subjects but join together in adults. This union occurs in and around the acetabulum, a sizable cup-shaped articular cavity that is located close to the center of the bone's outer surface.

genes turn on or off to regulate the activity of multiple choice rna. multifactorial disorders. differentiation. mutation.
Genes that are turned on or off to prevent the function of most RNA options are mutations. The process of turning genes on and off is called as Gene regulation.
Gene regulation is an important part of usual development. Genes are turned on and off differently during development so that brain cells form and function differently than liver cells or muscle cells, for example. Gene editing allows cells to respond more quickly to changes in their environment. A mutation is a change in the DNA sequence of organism. Mutations can result from DNA replication errors during cell division, exposure to mutagens or viruses. Genetic processes can occur at any time during gene expression, but most often occur at the level of transcription (when the information in the gene's DNA is passed down to mRNA).

according to chargaff's observations of nucleotide composition of dna samples ________.
According to Chargaff's observations of nucleotide composition of DNA samples, two key findings were made. Chargaff's rules state that in DNA:
The amount of adenine (A) is equal to the amount of thymine (T), and the amount of guanine (G) is equal to the amount of cytosine (C). This is known as base pairing or complementary base pairing. In other words, A=T and G=C.The overall composition of DNA varies between different species, but within a species, the amounts of A, T, G, and C differ. However, the ratio between A and T, as well as the ratio between G and C, is close to 1.These observations led to the development of the concept of DNA base pairing and the understanding that the two strands of DNA are complementary to each other.

In addition to intrinsic alterations in the contractile apparatus and sarcoplasmic reticulum function, muscle fatigue relates to considerable reductions in what mineral concentration?
In addition to intrinsic alterations in the contractile apparatus and sarcoplasmic reticulum function, muscle fatigue relates to considerable reductions in calcium concentration.
Muscle fatigue is the physiological inability of a muscle to sustain or generate force. It may occur in single muscle fibers or the entire muscle at the level of the neuromuscular junction. It is characterized by a decrease in the force-generating capacity of a muscle or muscle group due to previous exercise.
The role of calcium in muscle fatigue: Calcium ions play a vital role in muscle contraction by binding to the regulatory proteins troponin and tropomyosin, causing them to change shape and expose the binding site for the actin-myosin cross-bridge. A decrease in the concentration of calcium ions in the muscle cells results in reduced actin-myosin interactions, which is one of the primary causes of muscle fatigue. As a result, calcium pumps in the sarcoplasmic reticulum and the sarcolemma actively transport calcium ions out of the cell to restore calcium homeostasis, allowing the muscle to relax and return to its resting state.

hope it help though...Explain how an adaptation can enable an organism to survive a long-term environmental change. Describe and example to support your answer
Answer:
survival of the fittest
Some die, some survive. Those that survive to reproduce pass along their genes. Some survive by good luck. Others survive because they happen to have some quality that gives them a better chance to tolerate the environmental changes. Assuming those qualities are heritable, they’ll become more common in the genes of the surviving population. Eventually they’ll predominate. The population will have adapted to the changes.
With the exception of very primitive organisms, living animals have various senses including those familiar to us as sight, sound, touch, taste, and smell. Certain organisms have senses that we do not share. For instance, the class of snakes we call “pit vipers” have a specific organ that senses heat from prey animals, even in total darkness.
Bats use echolocation, bouncing high-pitched sound waves off of obstacles and prey alike. So do dolphins.
Many insects have the ability to smell only a few molecules of pheromones from potential mate
I took the question differently than everyone else, but it sounded to me like the OP was asking for examples of HOW organisms adapt, not two organisms that adapted.
Adaptation often begins with environmental monitoring systems. Lets say antibiotics are taken by a patient and a small amount gets in the area of a pathogen who is testing its environment. The pathogen detects the threat and begins to construct a genomic edit that can counter it. Unfortunately for us, cells are still more skilled with biochemistry than humans.
If you mean like to adapt in an instant, we humans release adrenaline to overcome stress and it actually makes us more prone to overcome stress. Another example its σ32 is the heat shock sigma factor in Escherichia coli, which it helps the bacteria to survive in a “heat shock”.
When we look at evolution, we often look at bacteria or animals that aren't really related to us, like the dinosaurs and how they evolved into avian animals.
There are two examples in human history that are great for this question.
Humans
Yup. People have made adaptations to the environment. Well, at least the environment that we create for ourselves.
Milk contains lactose, which requires a special enzyme to break down. After a few months of age, babies lose this enzyme and become lactose intolerant. So why can we drink milk now?
That's because in our past, farmers began to drink milk from other an

(2) Mitochondria losing unnecessary genes for symbiosis w/ eukaryotes
this is a miracle of evolution as we have read in our childhood about camels and about xerophytes(cactus) they got adapted to their environment but according to Darwin there is survival of the fittest which means there may be various types of a single species now under a harsh environment it may be that not all types of a single specie lives so they perish
