Explanation:
Many small freshwater organisms have a structure called a contractile vacuole, which pumps water out their body. Explain how this process is an example of active transport.
Answer:
1: The process of osmosis would cause water to move into the cells causing them to swell and possibly burst. Many freshwater one celled organisms have structures called contractile vacuoles. These structures collect and pump out excess water that accumulates in the cell.
2: During active transport, a protein pump uses energy, in the form of ATP, to move molecules from an area of low concentration to an area of high concentration. An example of active transport is the sodium-potassium pump, which moves sodium ions to the outside of the cell and potassium ions to the inside of the cell.

Explanation:
The nucleus has a system of _____ embedded within its outer membrane which allows communication between the nucleus interior and the cytoplasm.
Answer:
pores
Explanation:
The nucleus consists of "nuclear pores" on its outer membrane. Each of these are surrounded by nuclear pore complex. It allows the pore to regulate the movement of molecules between the nucleus and the cytoplasm. It allows small particles to pass through such as ribosomal proteins. It prevents most large particles (except for histone) from passing through; thus, it is selective in nature. This function of the pores clearly shows that it allows communication to occur between the nucleus interior and the cytoplasm.

A frameshift mutation will change a.Only one codon b.Only two codons c.All codons both before and after the point at which the mutation occuredd.All codons only after the point at which the mutation occured
Answer: d. All codons only after the point at which the mutation occurred.
Explanation:
Mutation can be defined as the change that occurs at the genetic level.
A frameshift mutation can be defined as the genetic mutation in which the deletion or insertion of the number of the nucleotide in the sequence of DNA results.
The frameshift mutation changes the reading frame of the group of codon from the point where the change has occurred.
This results in the completely different translation from the previous sequence.

When the diaphragm contracts, the size of the thoracic cavity ________, the pressure inside the thoracic cavity ________, and air flows ________ the lungs. decreases; drops; out of decreases; rises; into increases; drops; into increases; drops; out of
Answer:
decreases; rises; out of
Explanation:
When the diaphragm contracts, the size of the thoracic cavity decreases, the pressure inside the thoracic cavity increases, and air flows out of the lungs.
During the process of breathing out, the diaphragm and the intercostal muscles relax and this leads to a decrease in the volume of the thoracic cavity. Since there is an inverse relationship between volume and pressure, the decrease in the volume of the thoracic cavity leads to an increase in its pressure. Consequently, the lung contracts and air is forced to leave it.
The diaphragm is a muscular structure, which is present below the lungs. The relaxation and contraction of the muscles help in the increasing and decreasing of the thoracic cavity during the breathing process.
The statement for the given blanks are:
When the diaphragm contracts, the size of the thoracic cavity increases, the pressure inside the thoracic cavity decreases, and airflow into the lungs.
The working of the diaphragm can be given as:
1. The diaphragm will contract during the inhalation process. The diaphragm will pull downward which will increase the size of the thoracic cavity and cause a decrease in pressure.
2. The change in the pressure will result in the rushing of air inside the lungs, and will fill up the lungs.
Thus, the contracting and relaxing of the diaphragm will result in the breathing process.

How does the cooling rate of magma affect the
texture of igneous rock?
Answer:
The factor that affects the size of the crystals and the texture of the rock is the cooling rate of the molten rock or magma. If the magma cools rapidly, the crystal formed is very small. ... On the other hand, if the magma cools slowly, the crystal formed is large. This rock has a coarse-grained texture.
Explanation:
The texture of an igneous rock is completely dependent on the rate of cooling of the melt. Slow cooling allows large crystals to form whereas fast cooling gives small crystals.
How is cooling rate of magma related to texture of igneous rock?If the magma cools quickly then the reactions are much more faster and smaller mineral crystals. Igneous rocks have a distinctive appearance based on the rate of cooling.
Cooling rate of the molten rock or magma is the factor that mainly affects the size of the crystals and texture of the rock. Crystal formed is very small, when the magma cools rapidly whereas, the crystal formed is large, if the magma cools slowly.
Rocks formed from the crystallization of a liquid are called Igneous rocks. Igneous rocks are divided into:
Intrusive rocks that crystallize from magma in the earth's crust. Extrusive rocks that crystallize from lava in the earth's crust.To know more about igneous rock, refer

_____________________________________[tex]\huge\textbf{Body Systems}[/tex]The human body is made of different body systems which help it to perform different processes and manage them. Body systems is made of different Body organs. They are listed below
Digestive SystemIt is also called Gastrointestinal(GI) System. The GI system starts from mouth and ends at anus. All the organs between and including the mouth and anus comes under GI system.
The GI system intakes food and breaks it down into small and diffusable nutrients and excretes the solid waste products. One of the most important purposes of food is to serve as cellular fuel. Also, carbohydrates, proteins, and fats can all be used by our cells as sources of the energy that they need to stay alive.
Cardiovascular SystemCardiovascular system provides a transit way for the Products. It includes heart, Veins, Arteries, Capillaries.
It moves blood, hormones, nutrients etc. The main function of the cardiovascular system is therefore to maintain blood flow to all parts of the body, to allow it to survive. Veins deliver used blood from the body back to the heart.
Renal SystemIt cleans dissolved waste products from the blood and excretes them. It includes kidneys and bladder. All blood is passed through the kidneys, where special filters allow dangerous substances to pass out of the bloodstream while keeping helpful substances in. The waste liquid that’s filtered out by the kidneys is stored in the bladder until the body expels it.
Endocrine SystemThis system sends secret chemical signals that allow body systems to act cooperatively as require. These secret messages have their own unique purpose, to which the body’s other systems respond accordingly.
Respriatory SystemThis system is involved with gaseous exchange. It includes lungs, bloodvessels, heart, blood etc.
The respiratory system provide the cell with the oxygen which is taken in by lugns from the environment. In exchange the cell gives the blood "Carbon dioxide" which is given out when we expire.
Nervous SystemThe Neuron system is made of brain, neuron etc. It allows perception, emotion, thought, and rapid response to the environment. It includes the brain and nerves. The nervous system allows us to sensory stimuli such as light, sound, smell, and touch from our environment.
Immune SystemThis system fights infection and includes lymphatic vessels which permeate the body. Every living thing needs to be able to fight infection. We have white blood cells that can specially target and destroy invading pathogens. These white blood cells are made in our bone marrow and stored in our blood and our lymphatic systems.
Reproductive SystemThis system is related to the production of offspring. It includes ovaries, uterus, mammary glands (breasts), penis, and testes. The reproductive system is not essential to individual survival, but it is essential for the survival of the species.
Muscular and Skeleton SystemThis system contains all the muscles and bones we have. It include smooth, cardiac, skeletal muscles which are involuntary and voluntary in function also hard rigid bones and cartilage.
It provides body support, shape and protection.

Cortisol is secreted by the cortical region of the adrenal gland and it increases the blood sugar levels.
Adrenaline is secreted by the medular region of the adrenal gland and it increases the heart rate.
Ad means upon and renal means kidney, thus adrenal gland is present at the top of the kidney. There are two regions in the adrenal gland,
Adrenal Cortex: Outer regionAdrenal Medulla: Inner regionx------------------------------------------------------------x
[tex]\Large\textbf{Adrenal Cortex}[/tex]
Adrenal Cortex is active all the time but especially in shock or stress condition. It secretes aldosterone, cortisol and androgenic hormones.
ALDOSTERONE: It promotes the retention of sodium ions and release of potassium ions by kidney. It also promotes inflammation as part of the body immune defense reaction.CORTISOL: It brings about an increase in blood glucose level mainly its production from protein and by antagonizing the action insulin.ANDROGEN: They play an important role in sexual development. As they secrete androgen and testosterone so they promote the secondary sex characters such as beards in men and sexual characters in woman._____________________________________[tex]\Large\textbf{Adrenal Medula}[/tex]The adrenal emdulla produces the hormones such as adrenaline and nor-adrenaline.
