The atmosphere is full of nitrogen gas (N2). But plants cannot use nitrogen in this form. Summarize the roles of bacteria in making nitrogen available to plants and in returning nitrogen to the atmosphere.

Answers

Answer 1

Answer:

Explanation:

Since plants cannot make use of nitrogen in this form, they need the help of some organisms which are Bacteria; nitrifying bacteria etc o help in the conversion of this form of nitrogen to that particular form mostly nitrates they can utilize directly.

Thus, most nitrogen is collected from the atmosphere and fixed by microorganisms such as bacteria to form ammonia, nitrites, and nitrates that can be used by plants. These organisms make use of the enzyme nitrogenase to aid in the conversion of atmospheric nitrogen (N2) to ammonia (NH3).

Nitrogen is returned to the atmosphere by denitrification which is the opposite if nitrification and is carried out by denitrifying bacteria. Nitrate is reduced to nitrogen through the production of some intermediate products.

Consider this animal cell. The organelles in an animal cell are labeled. Part D are stacked tubular structures. Which organelles are labeled D, and what is one feature that distinguishes them from the other labeled organelles? chloroplasts; the only organelles that produce sugars from sunlight ribosomes; only found in animal and bacterial cells centrioles; found in animal cells but not plant cells mitochondria; the only energy-generating structures found in cells

Answers

Answer:

The image of the animal cell was not included in the question, the image has been added as an attachment.

The answer is centrioles; found in animal cells but not plant cells

Explanation:

According to the question, the image in the attachment section is an animal cell with labelled organnelles. An animal cell does not possess a Chloroplast, which is unique to only plant cells. Hence, organnelles D cannot be Chloroplast.

Ribosomes are organnelles made up of a complex of RNA and proteins. They are the site of protein synthesis, which occurs in all living cells. Hence, all cells including plant and animal cells contain Ribosome organnelles. Therefore, it is a wrong choice.

Centrioles are cylindrical tube-like structures made up of microtubules arranged in a specific pattern. Centrioles are present only in animal cells and play a major part in cell division, where they organize microtubules that separate chromosomes. As seen in the image, the two centrioles are perpendicular to one another, forming a CENTROSOME. A plant cell does not possess centrioles instead they contain microtubules organizing centres (MTOC).

Mitochondrion are present in both animal and plant cells as energy-generating organnelles but they are not stacked tubular structures as described in the question.

Thymine 15%

Guanine 30%

Cytosine 30%

Explanation:

Remember Chargaff's rules: C=G, T=A.

A = T

.15 = T

Now we've got .30 A and T, so we know 1 - .3 = .7 of the DNA should be guanine and cytosine.

.7 / 2 = .35

When vinegar and baking soda react, the mixture becomes cold to the touch and a gas and a new liquid substance are formed. Which best describes what is occurring in the reaction?

Answers

Answer:

answer B The reaction is chemical and exothermic.

Explanation:

because on my quiz its b.

The described chemical interaction between vinegar and baking soda is an endothermic reaction since it involves the absorption of energy, which causes the mixture to become chilly. The correct option is A.

What is endothermic reaction?

A chemical reaction that is endothermic is one that increases the system's enthalpy through a thermodynamic process. A system engages in this process by absorbing energy from the environment, primarily thermal energy.

As a result, an endothermic reaction causes the system's temperature to rise while the environment's temperature drops.

Bonds are typically formed during endothermic processes, which demand energy input. Entropy of the environment is reduced during endothermic reactions.

Endothermic reactions frequently entail physical rather than chemical changes. The potential energy of the products exceeds that of the reactants in an endothermic process.

Thus, the correct option is A.

Quantitative data is data expressing a certain quantity, amount or range. Usually, there are measurement units associated with the data, e.g. metres, in the case of the height of a person. It makes sense to set boundary limits to such data, and it is also meaningful to apply arithmetic operations to the data.

What effect would overfishing most likely have on a population of fish in a lake?

Answers

Answer is B.


Overfishing would lead to a bottleneck effect, as large numbers of fish are removed from a fish population. Population size has a major effect on the amount of genetic diversity. The greater the population, the greater genetic diversity. Due to overfishing, the population would become smaller, which would reduce genetic diversity. So the answer is B.

8 What does the sample space represent?

Answers

Answer:

In probability theory, the sample space (also called sample description space[1] or possibility space[2]) of an experiment or random trial is the set of all possible outcomes or results of that experiment.[3] A sample space is usually denoted using set notation, and the possible ordered outcomes are listed as elements in the set. It is common to refer to a sample space by the labels S, Ω, or U (for "universal set"). The elements of a sample space may be numbers, words, letters, or symbols. They can also be finite, countably infinite, or uncountably infinite.[4]

For example, if the experiment is tossing a coin, the sample space is typically the set {head, tail}, commonly written {H, T}.[5] For tossing two coins, the corresponding sample space would be {(head,head), (head,tail), (tail,head), (tail,tail)}, commonly written {HH, HT, TH, TT}.[6] If the sample space is unordered, it becomes {{head,head}, {head,tail}, {tail,tail}}.

For tossing a single six-sided die, the typical sample space is {1, 2, 3, 4, 5, 6} (in which the result of interest is the number of pips facing up).[7]

A subset of the sample space is an event, denoted by E. Referring to the experiment of tossing the coin, the possible events include E={H} and E={T}.[6]

A well-defined sample space is one of three basic elements in a probabilistic model (a probability space); the other two are a well-defined set of possible events (a sigma-algebra) and a probability assigned to each event (a probability measure function).

Another way to look as a sample space is visually. The sample space is typically represented by a rectangle, and the outcomes of the sample space denoted by points within the rectangle. The events are represented by ovals, and the points enclosed within the oval make up the event.[8]

Read the following claim.

The energy animals need to survive was once energy from the sun.

What evidence from the article supports this claim? Think about energy pyramids, then explain how the evidence from the article supports this claim.

Answers

Answer: The energy from the sun is the only source of energy which has the ability to sustain life on earth.

The energy pyramid states that the transfer of energy is unidirectional and it flows from the producers to the consumers.

There are different trophic levels at which the organism are found say herbivores, carnivores and top predators.

All of the organism are dependent on the producers for their source of energy.

hence, the sunlight helps autotrophs to make food and herbivores feed on them and then the carnivores animals feed on herbivores and then the top predators feed on the carnivores animals.

So, ultimate source of energy on earth is sun, which directly or indirectly provides energy to the producers and other animals.

A study done in Burkino Faso, Africa, about the spread of malaria investigated the connection between beer consumption and mosquito attraction.1 In the experiment, 25 volunteers consumed a liter of beer while 18 volunteers consumed a liter of water. The volunteers were assigned to the two groups randomly. The attractiveness to mosquitoes of each volunteer was tested twice: before the beer or water and after. Mosquitoes were released and caught in traps as they approached the volunteers. For the beer group, the total number of mosquitoes caught in the traps before consumption was 434 and the total was 590 after consumption. For the water group, the total was 337 before and 345 after. 1Lefvre T, Gouagna L-C, Dabir KR, Elguero E, Fontenille D, et al. 2010 Beer Consumption Increases Human Attractiveness to Malaria Mosquitoes.
