The animal-like parasite plasmodium causes the disease
Answer:
Malaria is the answer
Explanation:
The animal-like parasite plasmodium causes diseases like malaria.
What is malaria?A parasite that frequently infects a particular species of mosquito that feeds on people can result in a serious and occasionally fatal disease known as malaria.
An obligatory parasite of insects and vertebrates, Plasmodium is a genus of unicellular eukaryotes. The parasite Plasmodium, which causes malaria, is spread via the bite of an infected mosquito.
Malaria often causes severe disease, including high fevers, shivering chills, and flu-like symptoms. Through the bites of female Anopheles mosquitoes carrying the parasites that cause malaria, people can contract this potentially fatal illness. It can be avoided and treated.
Therefore, malaria is brought on by the parasite plasmodium, which resembles an animal.

What are igneous rocks made of
A. a moisture of materials made from both living and no living processes
B. Materials that crystallized from magma or not lava, not from once living things
C. Materials that came from living things and that accumulated on the sea floor
D. Fossil fuels and other materials that came from once living things
Answer:
B
Explanation:
Igneous rocks are formed by the solidification of magma or lava.
Answer: Igneous rocks are made of B. materials that crystallized from magma or not lava, not from once living things
Explanation: Igneous rocks are formed from the solidification of magma, which is a hot (600 to 1,300 °C, or 1,100 to 2,400 °F) molten or partially molten rock material. Earth is composed predominantly of a large mass of igneous rock with a very thin veneer of weathered material—namely, sedimentary rock.

b) they can contaminate bodies of water
c) they can contain contaminants that can enter the air during storms or high winds
d) fertilizer use does not impact respiratory health
Answer: C) They can contain contaminants that can enter the air during storms or high winds.
Explanation: A is wrong because I got it wrong (Sorry, can't give much explanation there).
B is wrong because water contamination does not directly relate to respiratory health.
D is wrong because fertilizers can impact respiratory health (Explanation seems lack-luster, but I feel like this is common sense).

Explanation:
They can contain contaminants that can enter the air during storms or high winds.
Explain how thermohaline circulation is influenced by salinity and temperature.
Answer:
Thermohaline circulation is influenced by changes in density gradients. These density gradients are affected by the salinity and temperature of the ocean’s water. Cold water is denser than warm water and salt water is denser than freshwater. As water cools off, it sinks. As water evaporates, the salt concentration of the remaining water increases because the salt from the evaporated water remains. This causes the water to sink and circulate.
Explanation:
Changes in density gradients have an impact on thermohaline circulation. The salinity and temperature of the ocean's water have an impact on these density gradients.
What effect of thermohaline circulation?The distribution of heat to the polar regions is largely dependent on thermohaline circulation.
As a result, it impacts how quickly sea ice forms at the poles, which in turn affects other components of the climate system (such as the albedo, and thus solar heating, at high latitudes).
Both salt water and cold water are denser than warm or fresh water. Water sinks as it cools.
Because salt from the evaporated water persists, when water evaporates, the salt content of the remaining water rises. The water circulates and sinks as a result of this.
Therefore, thermohaline circulation is influenced by salinity and temperature.

How is local weather influenced by global patterns of atmospheric movement?
Answer: A mountain range in the path of prevailing winds can influence where precipitation falls. When humid winds blow from the ocean toward coastal mountains, they are forced to rise. The rising air cools and its water vapor condenses, forming clouds.
how far does a car travel in 0.75 h if it's moving at a constant speed of 88 km/h
Answer:
Distance = 66 kilometers
Explanation:
Given the following data;
Time = 0.75 hour
Speed = 88 km/h
To find the distance traveled by the car;
Distance = speed * time
Substituting into the equation, we have;
Distance = 88 * 0.75
Distance = 66 kilometers.
Therefore, the car will travel a distance of 88 kilometers.

PLEASE HELP!!!!! Describe in detail the process of dna replication
Answer:
DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. The replication process relies on the fact that each strand of DNA can serve as a template for duplication. DNA replication initiates at specific points, called origins, where the DNA double helix is unwound. A short segment of RNA, called a primer, is then synthesized and acts as a starting point for new DNA synthesis. An enzyme called DNA polymerase next begins replicating the DNA by matching bases to the original strand. Once synthesis is complete, the RNA primers are replaced with DNA, and any gaps between newly synthesized DNA segments are sealed together with enzymes. Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.

In order for cellular respiration to effectively provide the energy your body needs to do its job, which of the following organ systems are needed?
(You may choose more than one answer.)
-Digestive system
-Respiratory system
-None of these systems support cellular respiration.
-Circulatory system
3.
The respiratory system supports the skeletal muscular system by:
-he respiratory system does not support the skeletal muscular system.
-transporting oxygen needed to release energy from glucose to the body's cells.
-breaking down the glucose to release energy.
-digesting the glucose you eat.
Answer:
1A - Respiratory = trachea, lungs... however both arteries and veins move oxygen around the body, and are therefore valid answers
1B - Skeletal = bones
1C - Muscular = muscles
1D - Digestive = stomach, large/small intestine
1E - Circulatory = heart, veins and arteries
2. Cellular respiration is the conversion of sugar into energy the cell uses to function via various chemical reactions. Digestion is an example of this. Stomach acid breaks down food into sugars that cells break down further into energy to keep you alive
3. Bones contain bone marrow deep inside of them which is responsible for the creation of red blood cells. Your lungs can move air all they want but would be useless without red blood cells to take the oxygen to cells and take the CO2 away from them.

What does this pyramid tell us about the population?
The answer is A. The population is growing.
The pyramid tells us that population is growing continuously, the growth of population is equal in both male and female population.
What is population?Population is defined as the quantity or population of people living somewhere who are a particular social, cultural, economical, ethnic, or racial category. Making decisions can be aided by knowledge of how population parameters, such as size, regional distribution, age structure, or birth and death rates, vary over time.
The pyramid is used to show the growth in population of a country or population of the city. In the pyramid the growth of population is equal in both male and female population. The pyramid shows that the population of older generation is less than the population of younger generation peoples.
Thus, the pyramid tells us that population is growing continuously, the growth of population is equal in both male and female population.
