Where do plants get the nitrogen they need to create amino acids and DNA?
A. Plants get their nitrogen from nitrogen gas (N2), which moves into leaves through holes called stomata.
B. Plants take up nitrates (NO3-) from the soil and convert them into ammonia (NH3).
C. Nitrogen-fixing bacteria convert nitrogen gas (N2) into ammonia (NH3), and plants take up some of the ammonia (NH3) through their roots.
D. Both B and C are correct.
E. A, B, and C are all correct.
Answers
Answer: It is D because they get it from soil and the gas
Plants get the nitrogen they need to create amino acids and DNA - option D. Option B and option C are correct.
Plants get nitrogen which is essential to form amino acid and nucleic acid that is DNA. Plants can not get the nitrogen gas directly from the air therefore, the process called nitrogen fixation takes place.
In nitrogen fixation, atmospheric nitrogen is converted to nitrates and ammonia with the help of nitrogen-fixing bacteria.Lightning and rainstorm also assist in the fixation process.plants take up nitrate from the soil and convert them into ammoniaNitrogen gas is converted into ammonia (NH3) by bacteria, and plants take up some of the ammonia (NH3) through their roots to the shoot via the xylem.Thus, the correct answer is - option D. both B and C are correct.

3. M. Garcia noticed pain on the left side of his chest under his arm The pain was stronger the
next day and his wife noticed patches of a red bumpy rash in the area of the pain. By the time
he saw his doctor that afternoon blisters and additional red patches had emerged. The doctor
asked about childhood illnesses and confirmed that Mr. Garcia had had chickenpox.
What is the possible diagnosis?!
H
Answers
Answer:
The possible diagnosis of M. Garcia with chest pain radiating to the left arm and the presence of red patches and vesicles is Herpes zoster.
Explanation:
Herpes Zoster is a disease produced by the varicella-zoster virus, and has a history of having had chickenpox in childhood or youth.
The varicella virus remains dormant in the body for several years, and can reappear, presenting as a localized and painful rash that can produce a neuritis in the affected territory.
The clinical symptoms of the M. Garcia —pain in the thorax irradiated to the left arm, red patches and vesicle-blisters— associated to the antecedent of chickenpox make think of a diagnosis of Herpes Zoster.

What genetic condition results in the trait indicated by the blue color being
expressed in the individuals shown here?
Answers
Answer:
ressessive
Explanation:
because it is what present by its phenotype
Blue color being expressed in the individuals shown here is recessive trait.
What is recessive trait?In terms of genetics, the term "recessive" describes the connection between an observed trait and the two inherited forms of a gene associated with that feature.
Each gene has two alleles that an individual inherits from each parent. When a characteristic is recessive, both of the (recessive) alleles of the gene that causes the trait must be present for the trait to manifest. When there is only one copy of an allele, it has no effect at all.
This is in contrast to a dominant trait, which can only be expressed when one of the two alleles is present.
Therefore, Blue color being expressed in the individuals shown here is recessive trait.

When studying animal behavior, the distribution of organisms within a choice chamber can be studied to identify animal preferences. 20 Isopods are placed in a 2-choice choice chamber. A cotton ball dampened with distilled water is placed in Chamber A; A dry cotton ball is placed in Chamber B. After 15 minutes 2 Isopods are located in Chamber B, and 18 isopods are found in Chamber A. Perform the chi-squared test to determine if the distribution of isopods is significant or due to random chance.a. chi-squared is 1.20, no it is not significant.
b. chi-squared is 8.42, no its not significant.c. chi-squared = 12.8, yes it is significant.d. chi-squared is 18.59, yes it is significant.
Answers
Answer:
The correct option is c. chi-squared = 12.8, yes it is significant.
Explanation:
Available data:
20 Isopods are placed in a 2-choice choice chamber. Different conditions were applied15 minutes later: 18 isopods are found in Chamber A and 2 Isopods are located in Chamber B.H₀= Individuals will be equally distributed
H₁ = Individuals will not be equally distributed.
Chi square= ∑ ((O-E)²/E)∑ is the sum of the terms
O are the Observed individuals: 2 in chamber B, and 18 in chamber A.
E are the Expected individuals: 10 in each chamber
X² = ∑ ((O-E)²/E) = ((2 - 10)²/10) + ((18 - 10)²/10) = 6.4 + 6.4 = 12.8
X² = 12.8
Freedom degrees = K – 1 = 2 - 1 = 1(K = Independent variables = dry cotton and wet cotton)
Significance level, 5% = 0.05 Table value/Critical value = 3.8412.8 > 3.84 meaning that the difference between the observed individuals and the expected individuals in each chamber is statistically significant. Not probably to occur by random chances.
There is enough evidence to reject the null hypothesis. The distribution of isopods is statistically significant.I need helpppp please

A scientist places four identical cells into four different liquids, each with different concentrations of magnesium.

Answers
Answer:
The correct option is Z
Explanation:
Active transport can be described as the movement of molecules against a cell's concentration gradient; meaning the movement of molecules across the cell's membrane from a region of lower concentration to a region of higher concentration. From this, it can be deduced that to have active transport in the description in the question, the "body" (the cell or the liquid) with the most amount of magnesium took in more magnesium (showing movement against concentration gradient as the magnesium moved from the least side to the most side). Thus, the correct option is Z

Amylase is an enzyme found in saliva that breaks down starch . The enzyme is currently functioning at its optimal pH of 7 and optimal temperature of 32 degrees * C Which of the following could result in an increase in the reaction rate?
Choose 1 answer : А)Decreasing enzyme concentration B)Placing the reactants in an environment at 10 degrees * C C)Providing an environment with a pH of 9 D)Increasing substrate concentration
Answers
Answer: D- Increasing substrate concentration.
Explanation: Increasing substrate concentration could increase the rate of the reaction, as there would be more substrate to bind with the enzyme. Hope this helps have a great day :) btw i got it right on khan academy.
The option that could result in an increase in the reaction rate would be increasing substrate concentration.
For enzyme-catalyzed reactions, the substrates are the reactants of the reaction.
Generally for reactions, an increase in the concentration of reactants will increase the rate at which products are formed.
Thus, irrespective of the presence or otherwise of the amylase enzyme, increasing the substrate concentration would increase the rate of reaction.
Since the optimal pH and temperature remain 7 and 32 degrees Celsius respectively, changing these factors will only reduce the rate of reaction. Decreasing the concentration of the enzyme would also reduce the rate at which products are formed.

Which correctly lists three places that fresh water is found?
Answers
Answer:
Ice caps and glaciers - 69%
Groundwater - 30%
Surface water - less than 1 %
Explanation:
Fresh water is a type of water, found in nature, in which there is no salt. It is water suitable for consumption (provided it is treated) for humans and animals. Fresh water is also used in agriculture. Only about 2.5% of the water found on our planet is sweet. It is mainly found in polar caps and glaciers, groundwater, surface water.
With the growth of the world population, fresh water has become increasingly scarce. Overuse, waste and water pollution are the main problems related to fresh water today.
As it is a precious and scarce mineral resource, society must be aware that, in order not to run out of water in the near future, it is necessary to avoid waste, use it rationally and do not pollute rivers, lakes and water sources.
