O A. A scientific law has been proved with scientific evidence. A
scientific theory can change when new evidence is found that
does not support the theory.
B. A scientific law is supported by research. A scientific theory is only
an educated guess.
C. A scientific law describes how natural events happen. A scientific
theory is an explanation of natural events.
D. A scientific law involves mathematics. A scientific theory is a
description based on observations.
Answer: I belief its B. A scientific law is supported by research. A scientific theory is only an educated guess.
-Like theories, scientific laws describe phenomena that the scientific community has found to be provably true. Generally, laws describe what will happen in a given situation as demonstrable by a mathematical equation, where as theories describe how the phenomenon happens.

Which of the following characteristics do homologous chromosomes exhibit?.
Homologous chromosomes carry alleles of the same traits and therefore, carry the genetic information for the same trait.
Homologous chromosomes are a pair of chromosomes with the same gene sequence but of different origins - one paternal and the other maternal.
Thus, homologous chromosomes carry the same traits, although could be of different forms. For example, one of the chromosomes might carry a gene for tallness while the other might carry a gene for shortness even though both tallness/shortness represent a gene for height.

Describe how the Earth’s surface changed over time?
Answer:
Earth's surface is constantly changing. Wind, water, and ice break down large rocks and move sediments on the surface. It usually takes years for weathering, erosion, and deposition to cause noticeable changes. Some events, though, change Earth's surface much more quickly.There are basically 2 types of changes that occur to the earth's surface (i) Slow change and (ii) fast change. Fast changes occur through the actions of earthquakes, volcanoes, landslides, etc. while slow change takes time and has a process.
Explanation:
Our home planet Earth is a rocky, terrestrial planet. It has a solid and active surface with mountains, valleys, canyons, plains and so much more. Earth is special because it is an ocean planet. Water covers 70% of Earth's surface. When it comes to changes on the Earth's surface, the main processes to take into account are plate tectonics and the rock cycle as well as the sea-floor spreading. ... These collisions causes mountains and volcanoes to form on the plate boundaries and thus changes the shape and form of the landmass

The anterior rami of spinal nerves ______ are called intercostal nerves because they travel in the intercostal space sandwiched between ______.
Answer: T1-T11; two adjacent ribs
Explanation:
The anterior rami of spinal nerves T₁ - T₁₁ are called intercostal nerves because they travel in the intercostal space sandwiched between two adjacent ribs.
What are the rami of spinal nerves?A typical spinal nerve typically branches out into rami as soon as it exits the intervertebral foramen.The smallest of the two main branches is the posterior (dorsal) ramus. It innervates the skin of the back as well as the deep muscles of the back, such as the transversospinalis and erector spinae. The bigger of the two main branches is the anterior (ventral) ramus. The anterior ramus divides into numerous additional branches that innervate the upper limbs, lower limbs, and anterior and lateral regions of the trunk. Numerous anterior rami develop into nerve plexuses.Learn more about rami of spinal nerves here:

Part A
Tectonic plate movement is the reason why northern California has a very different landscape than southern California. Two different tectonic plates, each moving in different directions, border the western side of the North American Plate. Use the map to identify the two tectonic plates that border the North American Plate to the west.
map of the world's major and minor tectonic plates
Part B
On the map, take a close look at the boundary along southern California and Mexico’s Baja California Peninsula. The arrows on the map show the direction and speed of the plates along this boundary in millimeters per year. Based on the speed and direction of the arrows, identify the type of plate boundary at this location. Which landforms or events are likely to occur there as a result? (Hint: It may be helpful to model the motion of the plates using your hands or pieces of paper.)

a cockroach is a fast-moving insect. how can an animal with an open circulatory system be so speedy?
Cockroaches have 6 legs and each leg has 3 knees, 18 knees in total. Since the cockroach has so many joints in its legs its can accurately pick up speed when running away from something
An animal like a cockroach with an open circulatory system is so speedy because in these organisms tracheal system delivers oxygen throughout the body.
What is an Open circulatory system?An open circulatory system may be characterized as a type of circulatory system in which blood vessels are completely absent and blood generally flows freely through the cavities of the body. This type of circulatory system is present in arthropods.
Due to the absence of blood vessels, the flow of blood is extremely high in animals that have an open circulatory system. Apart from this, in cockroaches, oxygen is carried out through the tracheal system because of the absence of the lungs. So, it makes the process so speedy.
Therefore, an animal like a cockroach with an open circulatory system is so speedy because in these organisms tracheal system delivers oxygen throughout the body.

Explain how the rate of cooling magma affects the size of
the crystal that form.
Answer: When magma cools, crystals form because the solution is super-saturated with respect to some minerals. If the magma cools quickly, the crystals do not have much time to form, so they are very small. If the magma cools slowly, then the crystals have enough time to grow and become large.
How can offspring be created that have a specific phenotype and genotype?
Explanation:
The two things a Punnett square can tell you are the genotypes and phenotypes of the offspring. A genotype is the genetic makeup of the organism. This is shown by the three genetic conditions described earlier (BB, Bb, bb). The phenotype is the trait those genes express. But when it comes to apperences, a phenotype is an individual's observable traits, such as height, eye color, and blood type. The genetic contribution to the phenotype is called the genotype. Some traits are largely determined by the genotype, while other traits are largely determined by environmental factors.

What is the role of chromosomes in the cell nucleus?
Explain in 5 - 10 sentences
Answer:
Chromosomes are tightly packed DNA and proteins. The DNA and proteins take on a tightly coiled structure within the chromosome. The chromosomes are then kept inside the nucleus. Their role is to carry basic genetic material. This provides the cell with genetic information that's used to carry out different cellular functions. These functions include survival, growth, and the ability to reproduce.
