Read the blog entry below and answer the question that follows:At first I dreaded going to sixth grade camp. I was sure the food would be poisonous, I would freeze to death in my sleeping bag, and the other kids in my cabin would never talk to me. But was I wrong! In fact, it was the best week ever! I went horseback riding and participated in a ropes activity with a zip line course. After the course, I climbed to the top of a pole using only ropes and carabiner clips, and then I rappelled off the top. I even made a new best friend. Oh, by the way, the food was delicious. It tasted better than my mom's! (But don't tell her.)

Review the first sentence:

At first I dreaded going to sixth grade camp.

What is the connotation showing here?


The author was impatient and could not wait to get to camp.
The author was worried he/she might not enjoy camp.
The author welcomed the opportunity to go to camp.
The author was excited about going to camp.

Answers

The answer would be B. The author was worried he/she might not enjoy camp. 

He/She wasn't impatient because it said she "dreaded" it so that rules out A.
He/She wasn't welcoming the opportunity, because again, the word "dreaded" was used.
He/She wasn't excited because "dreaded" does not imply excitement. 

I think it's B. The author was worried he/she might not enjoy camp.

Because anyway I was just scrolling through the questions and I was just like I know this question I just did it a few days ago! So this is pretty much a verified answer! :)

Which of the following is not an organelle found ONLY in plant cells?

Answers

-Chloroplasts: Chloroplasts are the plant cell's "energy power plant" as well as mitochondria- they are involved in photosynthesis, making food and energy for the cell.

-Cell walls: Cell walls are rigid layers around the cell membrane. They are made of cellulose and help maintain the cell's shape and prevent it from swelling too much.

One organelle only in animal cells:

-Centrioles: Centrioles are structures that make spindle fibers for the movement of chromosomes in mitosis.

A different organelle:

-Vacuoles:

In plant cells, the vacuole is called a "central vacuole". The central vacuole is a large "balloon" that holds water, nutrients, ions, trash, etc. for the cell.

In animal cells, there are numerous smaller vacuoles. They have the same function.

The cell wall is only located in the plant cell

Which statement is true?A. Viruses produce their own energy.
B. Viruses are not living.
C. Viruses have organelles.
D. Viruses can reproduce by themselves.

Answers

B.  Viruses are not living.

A virus is nothing more than a packet of genetic material that does not display the characteristics of living organisms.  

Final answer:

Viruses are not living and they do not have organelles or produce their own energy.

Explanation:

The correct statement regarding viruses is B. Viruses are not living.

Viruses are considered non-living because they lack the necessary characteristics to be classified as living organisms. While they can infect and replicate within a host cell, they are unable to carry out essential life processes on their own.

Unlike cells, viruses do not have organelles and cannot produce their own energy. They are composed of genetic material surrounded by a protein coat, and they rely on host cells to replicate.

Which of the following lists the correct order of events in terms of the development of life?A) The earth forms, eukaryotes appear, prokaryotes appear, multicellular organisms appear.


B) The earth forms, multicellular organisms appear, prokaryotes appear, eukaryotes appear.


C) The earth forms, prokaryotes appear, eukaryotes appear, multicellular organisms appear.

Answers

Answer:

The correct option is C. The earth forms, prokaryotes appear, eukaryotes appear, multicellular organisms appear.

Explanation:

There are many theories made by scientists which explain the formation of the planet Earth and many other theories describe the formation of life on this planet. Some theories claim that the Earth was formed from the Sun and eventually it began orbiting around the Sun. The location of the Earth from the Sun was best for the formation of life on Earth.

Some hypothesis claim that life started on Earth in extreme heated conditions known as hydrothermal vents. Prokaryotic organisms were the first to get evolved. Some prokaryotic organisms engulfed smaller prokaryotes and gave rise to eukaryotes. These eukaryotes over time formed multicellular organisms.

Answer:

C. The earth forms, prokaryotes appear, eukaryotes appear, multicellular organisms appear.

Explanation:

What substance is insoluble in water?

quartz
vinegar
sugar
salt

Answers

As you indicate, quartz or silica is exceptionally stable because of its exceedingly low solubility. Thus, option A is correct.

What is the solubility of water?

The amount of an oil that will dissolve in the water column at a specific temperature and pressure is known as its solubility in water.

The compound's water solubility increases with increasing polarity. The high water solubility of BTEX chemicals is one reason why they are found in groundwater so frequently.

In pure water at neutral pH, room temperature, and pressure (a saturated silica solution under these conditions only contains 6 parts per million of silica dissolved in water).

Quartz is about water-insoluble at normal temperature. There is no need to be concerned about quartz crystals being harmed by frequent washing.

Therefore, quartz substance is insoluble in water.

Salt and sugar are soluble so we are left with being at and quartz.

So that there is more gene variation. Let's say if they all had the same genes, one specific disease would be fatal for the species' existence since they would all be the same. The diverse gene pool allows species to develop different characteristics that can help them defend against disease
