If Malaria is contracted, where within the body does it reproduce before attacking the red blood cells
Answer:
the liver
Explanation:
With some species of malaria, such as Plasmodium vivax and Plasmodium ovale, the parasite can lie dormant in the liver. It can therefore take up to a year for symptoms to develop (see life cycle above). Once inside the body, the malaria parasites grow and multiply inside the red blood cells.

which amino acid is chemically modified to form a key component of the connective tissue protein collagen?
Answer:
glycine and proline
Explanation:
First, a three-dimensional stranded structure is assembled, with the amino acids glycine and proline as its principal components. This is not yet collagen but its precursor, procollagen. Procollagen is then modified by the addition of hydroxyl groups to the amino acids proline and lysine.

Which of the following might make this ecosystem more sustainable?
A. if it supported more plant species, but fewer animal species
Answer:
Something that may make this sustainable is to remove food from there, or to add more animal species, particulary slightly invasive species that can eat the plants, and fast.
Oops didn't understand at first, yes this will make it more sustainable
Explanation:
To solve this we must be knowing each and every concept related to ecosystem. Therefore, an environment with a large variety of plant and animal species is the correct option.
What is ecosystem?An ecosystem is generated through the interaction of all life forms with each other as well as with the chemical and physical features of their surroundings, all of which are linked by the energy flow. It includes all of the living organisms in a given region in addition to their non - living things surroundings such as air, water, and sunshine.
Humans depend on ecosystems to meet their fundamental requirements. Ecosystems sustain us by providing safe drinking water as well as nutritious food. They supply raw materials for our clothes, housing, transportation, and energy needs. An environment with a large variety of plant and animal species is more sustainable ecosystem.
Therefore, an environment with a large variety of plant and animal species is the correct option.

Why is it important that the phospholipid has both hydrophilic and hydrophobic
regions?
Answer:
The formation of a micelle is a response to the amphipathic nature of fatty acids, meaning that they contain both hydrophilic and hydrophobic regions.
Explanation:
Biological membranes remain fluid because of the unsaturated hydrophobic tails, which prevent phospholipid molecules from packing together and forming a solid.

what is the purpose of motor nerve varicosities as they relate to smooth muscle?
Neuroeffector junctions are varicosities where motor neurons release neurotransmitters to non-neuronal target cells. These junctions can be observed along the axon.
The motor nerve varicosities RELEASE neurotransmitters onto smooth muscle cells.There are many varicosities along the axons of the neurons that feed smooth muscle cells. When autonomic neurons are stimulated, varicosities release neurotransmitters along their axons.These neurotransmitters then diffuse through the interstitial fluid to interact with receptors in the smooth muscle cells.Learn more in:

Carnivores that eat other animals
Carnivores that eat other animals is a situation which shows a biotic factor operating within an ecosystem. Thus, the correct option is D.
What are the biotic factors?
A biotic factor in an ecosystem is a living organism which shapes its surrounding environment. In a freshwater ecosystem, the examples of biotic factors might include aquatic plants, fishes, amphibians, and algae population.
An example of biotic factor should consist of living organisms such as the one "Carnivores that eat other animals". In this example, carnivores are the animals which eat other lower animals for their nutrition. Both the organisms are living hence are the biotic factors of an ecosystem.
Biotic factors of an ecosystem depends upon the abiotic factors for their survival such as water, climate, soil, temperature, and atmosphere, etc.
Therefore, the correct option is D.

during dna replication the chromosomes contract and the identical halves are called
Answer:
Explanation:
Sister chromatids
During DNA replication the chromosomes contract and the identical halves are called sister chromatids.
What is DNA replication?A double-stranded DNA molecule is copied to create two identical DNA molecules through the process of DNA replication.
Because every time a cell splits, the two new daughter cells must have the same genetic material, or DNA, as the parent cell, replication is a crucial process.
In prokaryotes, DNA replication takes place in the cytoplasm, whereas it happens in the nucleus in eukaryotes.
Before dividing, cells must copy their DNA. This promotes successful inheritance of genetic features by giving each daughter cell a copy of the genome.
The two identical copies of the DNA that are produced as a result of this replication are known as "sister chromatids," and they are connected to one another by a section of the chromosome known as the centromere.
Thus, the identical halves of chromosome is sister chromatid.

During the Flowing Water Model demonstration, observe the stream table while water is flowing through it. What do you notice? Record your observations on the lines below. You can use to Word Bank to help you describe what you see.
Answer:The speed of the water flowing downhill will be affected by the degree of incline, and any structures or topographical features in its path. The faster the water flows, the more erosion occurs. Water flowing downhill moves and deposits sand at the bottom of the river. The faster the water flows, the more sand will be deposited at the bottom. A delta at the mouth of a river forms in the same way. Although the formation of the “rivers” in this activity appeared very quickly, in reality rivers can take millions to billions of years to form a path from land to sea.

of the two cells represented in the figure, which would likely be more efficient at exchanging substances with the surrounding environment?
Cell A is more efficient at exchanging substances due to larger surface area to volume ratio.
Cell A is more efficient at exchanging substances with the surrounding environment than cell B because it has the larger surface-area-to-volume ratio. Larger surface area of the cell exchanges more substances with the surrounding environment.
While on the other hand, lower surface area of the cell exchanges less materials with the environment so we can conclude that cell A is more efficient at exchanging substances due to larger surface area to volume ratio.

How does the biodiversity in a food chain compare to the biodiversity of a food web?
Answer:
ExpWhat is Biodiversity?
Biodiversity and food webs
Biodiversity is referred to as the web of life because many microorganisms, plants and animals interact with each other. The relationship among species is an important part of biodiversity.
A food chain is a sequence of who eats whom. The usual order of a food chain is sunlight, plants, herbivore, omnivore and/or carnivore. In one type of farming food chain, green grass and wildflowers use sunlight to grow in a field maintained by a farmer called a pasture. A Billy (boy) or Granny (girl) goat grazes on these delicious plants in the pasture. A goat or any other plant-eating animal is called an herbivore. Animals that rely on the farmer for food and protection are domesticated. In turn, the goat provides milk, meat and wool for the farmer, his family, and others. Humans are omnivores, as they eat plants and animals. The goat also provides fertilizer. Microorganisms decompose the goats’ poop or excrements, which provides fertilizers for the grass and flowers to grow. This is one example of a simple food chain based only on green plants, goats, microorganisms and humans. Millions of food chains exist around the world. Food Chain
Food chains that are related in an ecosystem form a food web. In forest ecosystems, many types of herbivores eat the trees and other plant life. Carnivores, or meat-eating animals such as tigers, lions, and wolves, prey on herbivores. They usually prey on wild animals. Sometimes, if the habitats or homes of carnivores are destroyed, they may also attack goats, sheep or cows for food. For example, in India, farmers may lose their goats to tigers; in Eastern Africa, cows may provide lunch for lions and in Western Canada, wolves sometimes attack the domesticated sheep. Carnivores are an important part of biodiversity because they regulate herbivore populations so that they do not eat their favorite plant species to extinction.lanation:
