Viruses require __________ for growth (to spread).
bacteria
plants
animals
living cells (host)
Answer:
Living cells
Explanation:
Viruses require living cells. Viruses aim to replicate themselves, and cells do exactly that. By injecting their DNA into a living cell, the cell will replicate the virus's DNA and infect other cells, spreading it more and more in the organism.

The breaststroke is started in the dive position in the water
Question 4 options:
True or false
The breaststroke is not started in the dive position in the water. Therefore, the statement is false.
What is breaststroke?The breaststroke is not started in the dive position in the water. It started in a stationary position with the swimmer, which faces forward and floats in the water.
The swimmer then takes a breath followed by the beginning of the stroke by pulling both arms back simultaneously and lifting their head and shoulders out of the water.
The legs are brought together by the swimmer andglides forward before the repetition of the arm and leg movements. It is the butterfly stroke because of the dive position, as the swimmer resurfaces both arms extended above the head to begin the stroke.
Therefore, the breaststroke is not started in the dive position in the water as it is started in a stationary position with the swimmer facing forward and floats in the water.

This is an organism that relies on other organisms for its food and energy supply also called a heterotroph
Answer:
Consumer
Explanation:
This is because comsumers rely on eating other organisms for energy. They "consume" other organisms, which is where the name comes from.
Concentrated animal feeding operations that raise hundreds of animals in a single location often use manure lagoons to dispose of the manure. manure lagoons are ponds lined with rubber to prevent the manure from leaking into groundwater or nearby waterways. one pig produces 30 liters of manure each day, and the average feedlot holds 900 pigs. calculate the amount of manure produced by the feedlot after 30 days to determine the minimum capacity needed for a manure lagoon. a faulty manure pond leaks into a nearby lake. describe one effect this leak would have on the organisms living in the lake.
If there is a leakage of the manure pond into the near by river, the growth the nitrates and phosphates in the leak causes an overgrowth of algae leading to eutrophication.
What is a manure?A manure is that which is used to improve the fertility of the soil. It is composed of the nutrients that are required by the soil. We know that each pig produces 30 liters of manure each day, and the average feedlot holds 900 pigs. Hence, each day, 30 * 900 = 27000 litres of manure is produced.
Within a period of 30 days, a total of 27000 litres of manure * 30 = 810,000 litres of manure is produced. If there is a leakage of the manure pond into the near by river, the growth the nitrates and phosphates in the leak causes an overgrowth of algae leading to eutrophication.

When igneous rock is formed,the size of the rock crystals or grains is primarily dependent on
Answer:
The three factors that influence the textures of igneous rocks are the speed of cooling, the silicate content, and the water content.
Igneous rocks contain randomly arranged interlocking crystals. The size of the crystals depends on how quickly the molten magma solidified: magma that cools slowly will form an igneous rock with large crystals. lava that cools quickly will form an igneous rock with small crystals. 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 do we represent dominant and recessive alleles?.
When a group of proteins such as interferons and interleukins are released by the t cells, intercellular signals begin the immune response, what is the medical term used for the group of proteins?.
The cytokine describes the group of proteins such as interferons and interleukins that regulate cell communication, mainly produced by the immune system in normal and pathological conditions.
What is a cytokine?They are messenger molecules with a glycoprotein structure, whose lifetime is short and generally secreted in cascades.
They are produced by different activated cells, responsible for innate and/or acquired immunity, and regulate the immune and inflammatory response.
Therefore, we can conclude that the cytokine describes the group of proteins that regulate cell communication, mainly produced by the immune system in normal and pathological conditions.

Question 6 (1 point)
What 4 body systems are used for CLEANING
YOUR ROOM?
List each body system (4 systems should be
listed) and explain how each system helps the
body when you clean your room.
Here are the body systems we talked about in class. Use this list to help you recall the types of systems
in the body: Muscular System, Skeletal System, Nervous System, Circulatory System, Digestive System,
Immune System, Reproductive System, Integumentary System, Respiratory System, Excretory System
Answer:
The skeletal system:This system controls our bones so we aren't just a blob on the ground. Our bones help keep our important organs intact.
The muscular system works about the same way, it protects your bones so they don't grind against eachother when you move. Your muscles give you the ability to move.
Our organ system is what keeps us alive, you can't clean your room if your dead and if your room is hot you need your skin so you don't overheat and die.
Lastly of course is your respitory system, you need to bring when your moving about. Our ability to breathe gives our blood cells and our heart what they need to keep working.

compare and contrast the five types of evidence that support the theory of evolution
There are five lines of evidence that support evolution: the fossil record, biogeography, comparative anatomy, comparative embryology, and molecular biology. The basic idea of natural selection is that a population of organisms can change over the generations if individual having certain heritable traits leave more offspring than other individuals. The result of natural selection is evolutionary adaptation, a population’s increase in the frequency of traits that are suited to the environment. In modern terms, we would say that the genetic makeup of the population has changed over time, and that is one way to define evolution. Evolution leaves observable signs. There are five lines of evidence that support evolution: the fossil record, biogeography, comparative anatomy, comparative embryology, and molecular biology.
Enzymes _______ the activation energy threshold required to start a chemical reaction.
raise
lower
Answer:
lower
Explanation:
Enyzmes usually lower the activation energy required to start a chemical reacion. It's useful to remember enyzmes as compounds which help speeden up different chemical processes. They do this by decreasing the required activation energy and therefore increase the chance of a chemical reaction occuring.
Enzymes lower the activation energy threshold required to start a chemical reaction.
Definition of Enzymes: a substance produced by a living organism which
acts as a catalyst to bring about a specific biochemical reaction.
