An ecologist is studying Dunaliella salina a single celled algae in a local pond. The pond is located near a construction site and the ecologist wants to know what affect, if any, the construction site is having on the pond, as there has been a steady decline in the Dunaliella salina population. In order to complete their study the ecologist would like to examine the organelles inside Dunaliella salina. If they would like to examine the inner structure of the chloroplasts of an already dead Dunaliella salina, what microscope would be best suited for this task? *
A.)dissecting microscope
B.)compound microscope
C.)scanning electron microscope
D.)transmission electron microscope
In the given scenario, to see the structures of chloroplast scientists can use a transmission electron microscope. The correct option is D.
What is transmission electron microscope?Transmission electron microscopes (TEM) are microscopes that visualize specimens and basically create a much higher magnification of an image using an electron particle beam.
TEMs have the ability to magnify objects up to 2 million times.
Transmission electron microscopy (TEM) is a popular method for examining the ultrastructure of organelles.
TEM generates high-resolution pictures by passing electrons through an ultrathin segment of a sample and magnifying the resulting image with a series of lenses.
The electron beam of the TEM penetrates thin slices of biological material, allowing the study of individual components of cells and organelles.
Thus, the correct option is D.

Which sentence correctly states whether a question is scientific, and provides a correct explanation? “Is the lifespan of snowshoe hares, which are white in the winter and brown in the summer, affected by levels of winter snowfall?” Yes, because the question is specific. No, because the question cannot be tested in a laboratory. Yes, because the question has already been answered. No, because the question does not lead to a hypothesis.
Answer:
Yes, because the question is specific.
Explanation:
The given question is scientific because it comprise of logic and reasoning, this question only be answered after performing experiments in the laboratory in order to find the factor behind the change of color. The question is specific because it only occurs in hare and we have to know that this change in color occurs due to change in temperature of the environment or not. So we have to perform scientific investigation.

When scientists carefully measure the lichens and agree on their thickness and how often they appear which parts of the scientific cycle are scientists using
Answer:
This question is incomplete; the complete question including the options are as follows:
During a study of lichens and air quality in part of China, scientists measure the thickness of lichens and estimate how many rocks and trees are covered with lichens in one town. The scientists are following the scientific cycle of observing while using a systematic process, establishing facts, explaining facts, and then returning to the systematic process to collect more facts.
When scientists carefully measure the lichens and agree on their average thickness and how often they appear, which parts of the scientific cycle are the scientists using?
A- process and facts, because they are using a systematic method to measure and then record data
B- process and facts, because they are observing lichens and air quality and describing why they are related
C- explanation and process, because they are using a systematic method to measure and then record data
D- explanation and process, because they are observing lichens and air quality and describing why they are related
The answer is A. process and facts, because they are using a systematic method to measure and then record data
Explanation:
Scientific experiments follow a series of well coordinated steps. These steps range from making observations to analyzing data. In this experiment, which involves scientists conducting a study of lichens and air quality in a part of China, a scientific cycle is being followed.
However, the scientists get to a point where they carefully measure the lichens and agree on their average thickness and how often they appear. This point is where the ANALYSIS OF DATA in the experiment occurs. Therefore, the part of the scientific cycle they are using is PROCESS and FACTS, because they are using a systematic method to measure and then record data.
What is one way to analyze the results of an experiment?

7,351 round to nearest hundred
Answer:
7 400
Explanation:
7, 351
7 is the thousands
3 is the hundreds
5 is the tens
1 is the unit
to round of to the nearest hundred look at both the hundreds value and the tens value.
since the tens value is 5 , this means the hundreds value increases by 1.
therefore 3 turns into 4
7351 to the nearest hundred is 7400

Answer:
the date
Explanation:
A tide table shows the date, time, and height of the predicted tides. The type of tide that the given table represents is mixed semidiurnal.
What is a mixed semidiurnal tide?A mixed semidiurnal tide is a tide that has two high tides and two low tides of different magnitudes in each day. The interval between consecutive high tides or low tides is almost the same.
The height of the tides changes every day due to the gravitational pull of the Sun and the Moon on the Earth's ocean water. The influence of the Moon on tidal patterns is more significant than that of the Sun.
Therefore, a mixed semidiurnal tide is the one with two high and two low tides of different magnitudes in each day, which is represented by the given tide table. All of these characteristics indicate a semidiurnal tide pattern.

How could the tomato plant’s response to being eaten by a hornworm caterpillar be described as a function of homeostasis?
Answer:
The required answer is given below:
Explanation:
This can be clarified with the idea of induced resistance. it is the capacity of a plant to react to the specific compound delivered from the damaged body parts, The dispersion of the synthetic animates all different plants parts and different plants to be less delectable and thusly not wonderful to eat. In this manner the more the degree of harm to the plant, the higher the volume of synthetic compounds delivered, and consequently the less delicious the plants and lower the harms negative criticism instruments. Since this reestablished the plants to moderately consistent inner environments, this is homeostasis.
Hornworm caterpillar harms tomatoes plants leaves, leaving holes. When a tomato plant is eaten, it discharges a compound substance called methyl jasmonate. The last would be gotten by adjoining plant parts or other tomato plants. The open tomato plants hence turn out to be less scrumptious. Subsequently, the caterpillar in the wake of crushing the underlying aspect of the tomato plants would not have the option to proceed with the taking care of and in this manner feed on each other prompting their death, turning them to cannabis caterpillars.
Since trying to keep up the generally consistent interior condition plant discharges methyl jasmonate to forestall further harm and in this manner guarantees the soundness of the plant.
Which of the following describes the products of meiosis?
Answer:
Sry JK
Answer: In contrast to a mitotic division, which yields two identical diploid daughter cells, the end result of meiosis is haploid daughter cells with chromosomal combinations different from those originally present in the parent. In sperm cells, four haploid gametes are produced.
The product of meiosis is four haploid daughter cells with genetically different as compared to their parents.
What is Meiosis?Meiosis may be defined as the type of cell division in which a parent cell is able to synthesize four daughter cells that are haploid in nature. These daughter cells are genetically dissimilar with respect to their parents. It is also known as reductional division.
The process of meiosis generally occurs in the germ cells (sex cells) of males and females. The division of cells occurs twice in meiosis. Meiosis is generally completed in two steps that are as follows:
Meiosis IMeiosis II.These steps are further divided into Prophase, Metaphase, Anaphase, and Telophase. Overall, it significantly determines the nature as well as the characteristics of a cell
Therefore, the product of meiosis is four haploid daughter cells with genetically different as compared to their parents.
