Which combination correctly pairs a product from a reaction in the nitrogen cycle with a molecule synthesized by plants using that product
Answer:
(A) nitrates—proteins
Note: The question is not complete. The complete question is given below:
Which combination correctly pairs a product from a reaction in the nitrogen cycle with a molecule
synthesized by plants using that product?
(A) nitrates—proteins
(B) ammonia—carbohydrates
(C) nitrogenous wastes—nitrites
(D) atmospheric nitrogen—nitrates
(E) atmospheric nitrogen—ammonia
Explanation:
The nitrogen cycle refers to the cycle through which nitrogen is transferred for use through both living and non-living things, involving the atmosphere, soil, water, plants, animals and bacteria.
The nitrogen cycle is especially important for living things because nitrogen is essential for the formation of amino acids which form proteins.
The nitrogen cycle occurs in five stages:
1. Nitrogen fixation - Nitrogen gas from the air is converted to nitrate compounds by nitrogen-fixing bacteria in soil or root nodules. Lightning also converts nitrogen gas to nitrate compounds.
2. Nitrification - Ammonia is converted to nitrates by nitrifying bacteria in the soil.
3. Assimilation - Plants absorb nitrates from the soil and use them to make proteins. The plant is then eaten by an animal and are used to produce animal protein.
4. Ammonification- Decomposers break down the bodies of dead organisms, urine and faeces converting them to ammonia in the soil, which is then converted to nitrates by nitrifying bacteria.
5. Denitrification - Denitrifying bacteria in the soil break down nitrates and return nitrogen back to the air.
From the above stages and the options provided, the correct option is A - nitrates from the nitrogen cycle is converted to protein by plants.
POST-lab Question:
What would be the effect on the butterfly population if the coloration in the environment suddenly changed? (Example: green
butterflies are living on a green plant that suddenly turns brown and loses all its leaves).
Answer:
The butterfly population would decrease or die out.
Explanation:
If the population of the green butterfly had depended on these "green plants" or leaves, they would die out without them since they use these green plants to camoflauge and blend in with them. Its something they can use to hide away from predators, and be safe from them.

Phloem - A vascular tissue in land plants primarily responsible for the distribution of sugars and the nutrients manufactured in the shoot.
Roots - The part of the plant which is generally underground that anchors and supports the plant body. It absorbs and stores water and nutrients, and in some plants is able to perform vegetative propagation.
Root hairs - The rhizoid of a vascular plant or a tabular outgrowth of a trichoblast, hair-forming cell on the epidermis of a plant root.

generation after generation unless acted
upon by outside forces. This is known as the
(3 Words)
Answer:
Hardy-Weinberg equilibrium
Explanation:
The Hardy-Weinberg law is established in it is that in a sufficiently large population, in which the matings occur randomly and that is not subject to mutation, selection or migration, the gene and genotype frequencies remain constant from generation to generation, once a state of equilibrium has been reached that is reached after one generation at autosomal loci. A population is said to be in equilibrium when alleles from polymorphic systems maintain their frequency in the population through generations.

Charli thinks she does better on tests after she has had coffee in the morning. One morning she drinks a cup of Folger's coffee and then does very well (A-) on her chemistry test. She does it again before her next chemistry test and again does very well (B+). Now she is convinced her hypothesis is right?
Answer:
Her hypothesis is right.
Explanation:
The Charli's hypothesis is right because caffeine present in coffee helps in boosting of memory if consume it in a normal range. Recent research indicates that caffeine may enhance long-term memory of an individual. When the memory is boost so the individual has the ability to memorize more knowledge that leads to good performance in the examination so the caffeine present in the coffee helps Charli to give good results in the test and we can say that her hypothesis is right.

What gets filtered out of the blood in the nephrons due to high pressure? Select all that apply.
water
salts
fats
sugar
vitamins
protein
amino acids
ions
Answer:
Water, ions, glucose, fluids
Explanation:
This is because the nephron have network of cappilaries vessel called glomerulus . This glomerulus filter blood in the kidney to make urine. The hydrostatic force cause the filtrate to be filtered out through pressure.
The nephron also posses tubule which help to return needed or essential substances like protein, ions to the blood and then remove waste products from the blood.

Evolution Quick Check
Which of the following principles is NOT part of Darwin's theory of evolution by natural selection?
Evolution is the biological and chemical changes that occur over generations that results in the variation of the observable traits in the organism. According to Charles Darwin evolution happened because of natural selection and many other factors.
Mutations are the ultimate source of genetic variation.
What did Darwin's theory state?Charles Darwin gave the theory of evolution and natural selection in which the major points were variation, lineage, preference and duration.According to his theory mutations are not the ultimate source of the genetic variations as natural selection and many other factors play roles in the variation and speciation.Therefore, option C is correct and is not part of the theory.

Chain Pickerel is a freshwater fish that is a member of the pike family. Chain Pickerels are found along the Eastern coast of answers - The dissolved oxygen of the water decreases
The salinity of the water decreases
The amount of light penetrating the water increases
The temperature of the water increases in the summer
question - Florida all the way around to Texas. Sometimes called a "jack fish" or a "southern pike," pickerel feed mainly on smaller fish, ambushing them with sharp teeth. These fish are often found throughout the state of Florida in rivers, lakes and creeks. Spawning occurs in late winter to spring among heavy aquatic weed growth or flooded grasses, in water from a few inches deep to several feet deep. Large number of adhesive eggs are scattered over vegetation. Based on this information, which of the following scenarios would impact the population of Chain Pickerel and cause a decrease in the population size?
Answer:
the dissolved oxygen of the water decreases.
the fish need the oxygen for respiration, breathing through their gills.
Explanation:
The salinity decreasing doesn't affect the pickerel, because it's a freshwater fish. no salt needed.
more light penetrating the water just means that more aquatic weed or grasses would grow, giving the pickerel more area to spawn their eggs.
temperature increase in the summer has no affect on the fish, since the spawning happens in late winter.

In the human body, organ-systems interact with each other to maintain homeostasis. Using the diagram below, explain how this system interacts with another in the body to maintain homeostasis?
Answer:
D
Explanation:
Im pretty sure tell me if im right
Homeostasis is a regulating process of the body in response to external environments, digestive system provides glucose for cellular respiration.
How do organ systems interact to maintain homeostasis?Organ systems in our body are regulated with each other and these interactions maintain homeostasis.
The respiratory system interacts with the circulatory system for gaseous exchange and the excretory system depends on the circulatory system for blood filtration, and the nervous system regulates the system through the brain.
Homeostasis is necessary because the external environment can change anytime, and the digestive system maintains food conditions according to the body's needs.
Therefore digestive system maintains homeostasis by providing glucose for cellular respiration.
