What is brain?
The part the nervous system that contains the cerebrum and cerebellum is the brain. The brain is an organ in the body that controls different other activities in the body. Almost everything in the body is controlled by the brain. The three main parts of the brain is; cerebrum, cerebellum, brainstem. The cerebrum controls speech and emotion, the cerebellum controls movement and the brainstem controls sneezing, coughing.
Spinal cord is a part of the nervous system transports information between the brain and other parts of the body. The spinal cord is a tubular and thin structure composed of nervous tissue. The spinal cord functions are to the transmission of neural signals among the brain and other parts of the body. Spinal Cord is necessary because the brain communicates with the body through it.
Thus, the brain sends information by the spinal cord to the peripheral nerves everywhere to the body that serves to regulate the muscles and inner organs.

How can scientists investigate the impact of limiting factors on a population?
Answers
Answer: No population can increase without limitation. Instead, populations in natural ecosystems increase or decrease in response to the changes in the factors that restrict growth. Many factors influence population densities and growth, and these factors may lead to oscillations in population size over time. It is also often difficult to determine the exact factor limiting growth. Many different factors may combine to produce unexpected results.
Explanation: I hope this helps....
Answer:
Limiting factors include a low food supply and lack of space. Limiting factors can lower birth rates, increase death rates, or lead to emigration. Limiting factors determine the carrying capacity of a population.

4- Jamie does an experiment. She charges a pencil by rubbing it with a piece
of silk. Jamie finds that she can use the pencil to attract the silk. Why does
the attraction occur?
Answers
Answer:
More info given below.
Explanation:
This attraction occurs as a result of static charge. You see an atom is referred to as the smallest particle of a substance; and when an atom gains or looses electrons it becomes unstable creating a difference in potential. However in this case rubbing induces friction which induces heat. This heat excites the atom to loose electrons creating a negative charge on the silk and a converse positive charge on the pencil.

1. Describe one observation that supports the theory that mitochondria and chloroplasts originated as independent prokaryotic organisms
2.Explain how a symbiotic relationship like the one described in the endosymbiotic theory would have benefited each cell.
Answers
Answer: hope the below answers will help
Explanation:
1 and 2 in this paragraph
SKILLS TO DEVELOP
Briefly describe what is meant by the endosymbiotic theory.
Give some evidence supporting the theory that mitochondria and chloroplasts may have arisen from prokaryotic organisms.
It is thought that life arose on earth around four billion years ago. The endosymbiotic theory states that some of the organelles in today's eukaryotic cells were once prokaryotic microbes. In this theory, the first eukaryotic cell was probably an amoeba-like cell that got nutrients by phagocytosis and contained a nucleus that formed when a piece of the cytoplasmic membrane pinched off around the chromosomes. Some of these amoeba-like organisms ingested prokaryotic cells that then survived within the organism and developed a symbiotic relationship. Mitochondria formed when bacteria capable of aerobic respiration were ingested; chloroplasts formed when photosynthetic bacteria were ingested. They eventually lost their cell wall and much of their DNA because they were not of benefit within the host cell. Mitochondria and chloroplasts cannot grow outside their host cell.
Evidence for this is based on the following:
Chloroplasts are the same size as prokaryotic cells, divide by binary fission, and, like bacteria, have Fts proteins at their division plane. The mitochondria are the same size as prokaryotic cells, divide by binary fission, and the mitochondria of some protists have Fts homologs at their division plane.
Mitochondria and chloroplasts have their own DNA that is circular, not linear.
Mitochondria and chloroplasts have their own ribosomes that have 30S and 50S subunits, not 40S and 60S.
Several more primitive eukaryotic microbes, such as Giardia and Trichomonas have a nuclear membrane but no mitochondria.
Although evidence is less convincing, it is also possible that flagella and cilia may have come from spirochetes.

EXAMPLE 7.8.1
Briefly describe what is meant by the endosymbiotic theory.
Give three points of evidence supporting the theory that mitochondria and chloroplasts may have arisen from prokaryotic organisms.
Solutions
The endosymbiotic theory states that some of the organelles in eukaryotic cells were once prokaryotic microbes.
Mitochondria and chloroplasts are the same size as prokaryotic cells and divide by binary fission.
Mitochondria and chloroplasts have their own DNA which is circular, not linear.
Mitochondria and chloroplasts have their own ribosomes which have 30S and 50S subunits, not 40S and 60S.
Summary
The endosymbiotic theory states that mitochondria and chlopoplasts in today's eukaryotic cells were once separate prokaryotic microbes.

D. it's surface area increases more rapidly than it's volume increases

Write a summary of the pathways rocks can take to become sedimentary, igneous, and metamorphic rocks.
Answers
Answer:
When a certain type of rock, specifically, an igneous rock, is deeper into the ground, and it is under the influence of high temperatures and pressures, it will start to change its molecular structure over time. In addition to the high temperature and pressure, chemical influences are also very important, so the the rock will gradually turn into a metamorphic rock.
Depending on the type of influences, and their intensity as well, one type of rock can evolve into multiple different types of metamorphic rocks.

The offspring will be black because they are heterozygous for a dominant trait that is controlled by monogenic inheritance.
Explanation:
Guinea pigs will be heterozygous because they inherit a dominant allele that encodes for the black color and a recessive allele associated with the white color.

Answers
Answer:
Species X and Y are related to humans.
Explanation:
The chart shows information about three different embryos early in their development. The best supported by the information in the chart is that Species X and Y are related to humans. Thus, option D is correct.
What is an embryo?An embryo refers to the early development stage with respect to the multicellular organism. The organism should be again produced se-xually. Moreover, the development of embryonic should be a portion of the life cycle just done after fertilization and continued via when the structure of the body is formed like tissues and organs.
The development of embryonic i.e. used for proof with respect to evolution should be related species that contain the same embroys.The similarities during the embryo stage of development among different animals are due to the expression of ancient genes.
These ancient genes have the same evolutionary origin, thereby they are homo-logous sequences. For example, fish embryos and human embryos express certain homo-logous genes in the embryos stage, thereby leading to the development of gill slit during this stage.
Therefore,Thus, option D is correct.

An active transport process by which a vesicle moves a large substance out of the cell is known as __________.
osmosis
endocytosis
exocytosis
diffusion
Answers
Answer:
I'm pretty sure it is exocytosis. Because exocytosis transports vesicles out of the cell through the plasma membrane. Remember it as "exo" = exit.
Answer:
C. Exocytosis
Explanation:
The first thing we notice is that the question says "active transport". Looking at the answer choices, we see that "osmosis" and "diffusion" are options.
However, remember that osmosis (the diffusion of water from high to low concentration) and diffusion (the movement of particles from high to low concentration) are both passive transport; in other words, they don't require an input of energy. So eliminate them.
Now look at endocytosis and exocytosis. "Endo" means "inner", so "endocytosis" means the cell is engulfing a substance and bringing it inside. However, we want the process where a substance is moved out.
"Exo" means "out", so "exocytosis" means to expel something. That matches here, so our answer is C.
