Answers

Answer 1

Answer: PLEASE MARK ME AS BRAINLIST

Explanation:

The cell was first discovered and named by Robert Hooke in 1665. He remarked that it looked strangely similar to cellula or small rooms which monks inhabited, thus deriving the name. However what Hooke actually saw was the dead cell walls of plant cells (cork) as it appeared under the microscope.

the German botanist Schleiden proposed that all plants are made up of plant cells. Thank you.

Territorial animals like spiders that fight off intruders would be expected to be _______. a. regularly distributed b. randomly distributed c. clustered together d. b and c

Answers

Answer:A

Explanation:

I took test on edge. and it was right

Territorial animals like spiders should be distributed regularly. If they clustered close, they may all die at once and lose territory. So, they're regularly disseminated to battle predators and intruders and protect their territory.

Why do animals defend their territory?

Territorial behavior is adapted in many different ways; for example, it may allow an animal to mate without being interrupted or to rear its young in an area where there will be little competition for food. Both of these things are adaptive. In addition to this, it can minimize overcrowding by preserving the ideal space between individuals within a community.

It is reasonable to anticipate that territorial animals such as spiders will routinely distribute themselves. They had to do this in order to protect their area because if they huddled together, there was a greater chance that they would all perish at the same time, which would result in the loss of territory. As a result, in order to prevent this from happening, they are routinely dispersed, and they are able to defend their region against invaders and predators.

Which of the following is NOT true of saturated and unsaturated fats? A. Saturated fats are saturated with hydrogen while unsaturated fats are not because they do not have electrons available to bond with hydrogen. B. Saturated fats can pack more tightly and form solids at room temperature while unsaturated fats are liquid at room temperature. C. Saturated fats, because they lack double bonds between their carbon atoms, stay liquid at room temperature while unsaturated fats form solids.

Answers

Answer:

Saturated fats can pack more tightly and form solids at room temperature while unsaturated fats are liquid at room temperature.

The statement which is NOT true about saturated and unsaturated fats is Choice C: Saturated fats, because they lack double bonds between their carbon atoms, stay liquid at room temperature while unsaturated fats form solids.

Generally, fats are classified as either Saturated or Unsaturated fats.

Saturated fats are fats which are saturated with hydrogen, and consequently have only single C-C bonds.

Contrarily, unsaturated fats are not saturated because they lack available electrons to bond with hydrogen and consequently, have double bonds between successive Carbon atoms in their structure.

As a result of the statements above;

Saturated fats can pack more tightly and form solids at room temperature while unsaturated fats are liquid at room temperature.

Inference from the statements above therefore suggests that the statement which is not true is Choice C: Saturated fats, because they lack double bonds between their carbon atoms, stay liquid at room temperature while unsaturated fats form solids.

The replication cycle of T7 virus has several things that none of the other virus replication cycles include. What is one of these things? I cant find anything on google shhssgxhahshsb or im just lazy

Answers

Answer:

Lysogenic replication cycle is one unique process in T7 virus replication.

Explanation:

The T7 virus is a virus that attacks bacteria ( bacteriophage). Unlike other viruses (plants and animals viruses), it replicates within the host cell by means of two cycles: the lytic replication cycle and the lysogenic replication cycle.

Virulent phages replicate through the lytic replication cell and this lead to the death of the cell through cell lysis.

The lysogenic replication cycle involves bacteriophages known as temperate bacteriophages. Temperate bacteriophages can become part of a host chromosome forming a prophage. The prophage replicates with the formation of daughter cells with incorporated viral genetic materials until when induced to enter into the lytic stage thereby producing new viruses which then exit the host cell by cell lysis.

This process of incorporation into the host cell genome is known as lysogenic replication and is unique to the bacteriophages.

Viruses are neither living nor dead organisms. The viruses require a host to replicate. The virus follows the lysogenic or lytic cycle to replicate. The T7 virus follows the lysogenic replication pathway.

The T7 virus follows the lysogenic pathway, in which the nucleic acid of the bacteriophage is incorporated into the host genome. The T7 virus intervenes on the bacteriophage genome.

In the lysogenic cycle, bacteriophages can become part of the host genome. This genome is then known as prophage. Prophage replicates and forms the daughter cells with the altered genetic material of the host.

The new cells produced are released by the lytic cycle, in which the cell produces new cells by lysis.

Thus, the incorporation of the host cell genome in the bacteriophage via the lysogenic cycle is a unique feature of a virus, T7.

write a letter to your headmaster why moral lesson should be instill into students ​

Answers

Dear Mrs. Been.

In view of the importance that you have in our educational environment in relation to the position of headmaster that you occupy, I would like to emphasize the importance of classes with moral lessons, in the hope that you will authorize and encourage this type of lesson in our school.

The most important positive point of adopting this type of lesson is to teach students to distinguish correct and incorrect elements, about behaviors and concepts. This will allow for the formation of conscious adults with great rational capacity.

Another positive point is the ability to encourage students to solve ethical and moral problems that develop from a non-linear point of view, as most problems in the real world present themselves. By seeing and solving these problems in the school environment, students will be better prepared for the future that awaits them.

Last but not least, I would like to point out that students who have well-stimulated and trained moral concepts are better able to promote not only personal benefits, but also social, political and economic benefits for the communities in which they operate.

I look forward to your comments on this suggestion.

Kind regards,

Mary Lang

Dear Mr Peter,

Education is important to the growth and the development of the country and and since you play a vital role as a leader in this educational institution, I'll like to emphasize the importance of moral lessons to the students.

Moral lessons are important as they help in shaping the future of the students. When students are taught moral lessons, they will have good behaviors which will be vital to the nation.

Moral lessons can also enable the students know the difference between the rights and the wrongs on the society and enable them to be better citizens in the society.

Lastly, moral lessons can help in the promotion of peace and unity. When the students have good behaviors, they look out for each other and see always willing to help one another. This helps in promoting unity and peace in the school and the society at large.

In conclusion, I'll be glad if my letter is given a positive reply and moral lessons are instilled into the students.

Yours faithfully,

John.

You have planted corn in a field with clay soil. The field is predominantly flat with a slight slope at one end where a creek borders the field. You notice that germination and growth is slowest in the flattest portion of the field. Conversely, you also notice that you received good germination and rapid growth on the slight hill which meets the creek. You wonder why there should be differences in growth and germination in different parts of the field. Is it due to the extra water near the creek? Is there something different about the soil in that portion of the field, or is it due to the difference in slope (north, south, east, and west). 1. What is your hypothesis for this problem? 2. Design an experiment to test the hypothesis you have written (make sure you include a procedure [step by step list of what you will do], an IV, a DV, treatments, trials, and constants).

Answers

Hypothesis: The soil in the flat part of the field has less fertility than the soil on the small hill.

Experiment:

The experiment will be carried out in a greenhouse, to promote a controlled environment and equal to all plants used in the treatment.

In this experiment, the influence of the difference in fertility of the soil samples, in the flat part of the land and in the most inclined part, in the germination and growth of corn plants will be tested.

Corn seeds of the same species will be selected. All seeds will be sanitized and will go through the same dormancy breaking process, so that all of them have their germination stimulated.

Vessels with a capacity of 30 kilos will be caught. These pots will be cleaned, sterilized and filled with the same amount of soil collected in the field and with two corn seeds. It will be used 10 pots with soil that was collected in the flat part of the land, 10 pots with soil from the sloping part of the land and 10 pots with fertilized substrate containing high levels of fertility.

The pots will be placed in a greenhouse and will be irrigated with distilled water, to avoid contamination by possible substances in the water.

The pots will remain in the greenhouse for 100 days, where the behavior of seeds and plants in each of them will be observed and noted. After this period, a comparison will be made between the vessels of each treatment, assessing the differences between them and reaching the conclusion whether the hypothesis is true or false.

From a young age, kids have been introduced to the idea that a good job and a stable income helps them mentally, and physically. Despite its underlying materialism, this idea is undoubtedly true in the world today, for what limits the pursuit of happiness in life? Other than being able to afford the basic essentials to live your life? That being said, money definitely plays some sort of role in the production of happiness in someone's life, but only for a short period. -----------------------------------------------------------------------------------------------------Considering the fact that some people have not been personally introduced to extreme wealth or a "rich" way of living, some people might be happy with what they already have in life. But, for younger generations, social media and the internet present a seemingly unattainable and lavish lifestyle that fuels the yearning for more than what they have. In his article "Money and Happiness", Christopher Peterson, a former professor of psychology at the University of Michigan and author of the book The Good Life, claims "Research shows that income has a positive relationship with happiness (life satisfaction), although it is not a straight line. Therefore, being able to afford expensive items creates a sort of satisfaction with the buyer. Which in turn makes them content with how their life may be. But this usually is not the case. This sense of material satisfaction does not last long. While the feeling of satisfaction from buying an expensive item might feel like a lifetime, the feeling longing for something better will always remain in the mind of that person. For example, in Tolstoy's short story "How Much Land Does a Man Need? The protagonist of the story, Pahom, ends up always feeling unsatisfied with what he has, and looks for new ways to better his material possessions. This ultimately leads up to his untimely death. As Peterson explained, this is not as easy as a one plus one situation. The psychological effects of wealth can be very complex, and sometimes may cause one to become mentally drained in their mission to feel some sort of completion from buying their way into happiness. That being said, one cannot expect to have better possessions and instantly feel much more satisfied than they did before. Wealth cannot help one attain intimacy, friendships, and even a sense of accomplishment, just as how it can not save us from psychological problems including anxiety, depression, or addictions. Even with the correct treatment, it does not always guarantee a life of happiness for those who are treated by medicine or therapy.
