Answer:
We are all familiar with the basics of viruses: These particles infect living cells and wreak havoc throughout the body. But viruses aren’t the only villains around causing chaos in living things. Other infectious agents called viroids and prions — which are also tiny but powerful — can take down both plant life and entire animals.
Viroids are free RNA molecules of low molecular weight without any protein coat, while viruses can have either RNA or DNA molecules encapsulated in a protein coat. Viroids are smaller in size than viruses.
Viroids not made of cells.
Viroids don’t transform energy.
Viroids can’t reproduce on their own.

A femur is a leg bone found in a human skeleton. When evaluating the human body's levels of organization, a femur is best classified as —
A.
an organ, because it is part of the skeletal system.
B.
an organ system, because it is composed of many cells.
C.
an organelle, because it is composed of many tissues.
D.
an organism, because it is part of the skeletal system.
Answer:
Option A
Explanation:
The femur is classified as an organ, because it is part of the skeletal system
The level of organization is the order that includes cells, tissues, organs, organ systems, and organisms. The femur is a leg bone which is an organ which is a part of organ system called the skeletal system.
What is skeletal system?The basic framework of body is skeletal system, which is consists of bones, connective tissue, tendons, ligaments, etc.
The four main parts of this system include:
Bone.Ligament.Tendon.Joint.The femur is a leg bone which is an organ that is a part of an organ system called the skeletal system.

What effect does the deer's behavior have on the survival and reproduction of these two
types of cactus?
PLS HELP
Answer:
Greatly affected.
Explanation:
The deer's behavior has greatly affected the survival and reproduction of these two types of cactus because one cactus is eaten by deer while the other is saved from it. The cactus with no spines are eaten by deer which destroy the vegetative as well as reproductive parts of cactus so its survival and reproduction does not occur whereas the other cactus have spines on its body is save from deer and increase in the chances of survival and reproduction occur.

What is a main difference between Mercury and Neptune?
Mercury is an inner planet with a thicker atmosphere and a longer year than Neptune.
Mercury is an inner planet with a thinner atmosphere and a shorter year than Neptune.
Neptune is an inner planet with a thicker atmosphere and a shorter year than Mercury.
Neptune is an outer planet with a thinner atmosphere and a shorter year than Mercury.
Answer:
B because Mercury's orbit is 88 days and Neptune's is 164 earth years
Mercury is an inner planet with a thinner atmosphere and a shorter year than Neptune.
What is Mercury and Neptune?
Since 2011, Neptune has spent 12 years in the sign of Pisces, which it rules and enjoys being in. Mercury spends just 15 to 60 days in each sign of the zodiac, but because of the Mercury retrograde, they come together and hang out for a while.
This is incredibly uncommon. It may be said that Mercury, the hare, is enjoying a Long sleep with Neptune in a dreamy fog and has forgotten his responsibilities as a courier around the Earth.
When Mercury conjoined the Sun on March 14 at 24 degrees Pisces and then today, on March 25, when Mercury conjoined Neptune at 16 degrees Pisces, this was notably felt.
Therefore, Mercury is an inner planet with a thinner atmosphere and a shorter year than Neptune.

what do the arguments for and against the use of stem cells in medical research share?
Answer: Stem cell research can potentially help treat a range of medical problems. It could lead humanity closer to better treatment and possibly cure a number of diseases:
Parkinson’s Disease
Alzheimer’s Disease
Heart Diseases, Stroke and Diabetes (Type 1)
Birth Defects
Spinal Cord Injuries
Replace or Repair Damaged Organs
Reduced Risk of Transplantation (You could possibly get a copy of your own heart in a heart-transplantation in the future
Stem cells may play a major role in cancer
Better treatment of these diseases could also give significant social benefits for individuals and economic gains for society
Cons
"We should not mess with human life."
"Humans should not be trying to play God"
Some argue that stem cell research in the far future can lead to knowledge on how to clone humans. It is hard to say whether this is true, but we have seen devastating consequences of other research-programs, even with good intentions, such as nuclear research.
Stem cells are cells, which have the ability to transform into many different types of cells. The stems cells have the potential to specialize in any type.
The stem cells are extensively used for research, curing diseases, and especially in developing prosthetics. The stems cells provide new cells for the growth and development of the replaced and damaged cells.
The arguments for and against the use of stem cells are:
Arguments for the use of stem cells in medical research are:
1. The stem cells enhance the growth and development of healthy skin tissue.
2. The cells can be used to enhance the production of collagen.
3. The study of stem cells helps in understanding the causes of disease.
Arguments against the use of stem cells in medical research are:
1. The use of stem cells for research harms human life and dignity.
2. People believe that killing blastocysts or stem cells is equal to taking a human life.
3. However, the transplant of stem cells can be rejected by the patient's body, therefore, can cost the life of the patient.
Therefore, the use of stem cells for research can be fruitful or disadvantageous.

1. What do DNA Replication and Cell Division have in common?
2. Define Cell Differentiation in your own words.
3. Why are stem cells consjdered unique?
Answer:
1: During every cell division, a cell must duplicate its chromosomal DNA through a process called DNA replication. The duplicated DNA is then segregated into two "daughter" cells that inherit the same genetic information. This process is called chromosome segregation.
2: Cellular differentiation is the process in which a cell changes from one cell type to another. Usually, the cell changes to a more specialized type. Differentiation occurs numerous times during the development of a multicellular organism as it changes from a simple zygote to a complex system of tissues and cell types.
3: Stem cells have unique abilities to self-renew and to recreate functional tissues. Stem cells have the ability to self-renew. Unlike muscle cells, blood cells, or nerve cells—which do not normally replicate— stem cells may replicate many times.

List the four steps of mitosis in order. Describe what is happening during each phase.
Answer:
The four stages of mitosis are known as prophase, metaphase, anaphase, telophase. Additionally, we'll mention three other intermediary stages (interphase, prometaphase, and cytokinesis) that play a role in mitosis. During the four phases of mitosis, nuclear division occurs in order for one cell to split into two.

Why would so many earthquakes originate along the slab of lithosphere that is descending into the mantle?
Answer:
As the slab descends into the mantle, rheology changes cause the plate to bend and deform, and generates these earthquakes. The trend of such events can be seen in cross-sections of subduction zones
Explanation:
Which generalization can be made from the data in the table?
1.The higher the temperature, the fewer chirps there will be in 10 seconds.
2.The chirps occur closer together as the temperature increases.
3.The chirps become farther apart as the temperature increases.
4.There is no relationship between temperature and the time between chirps.
The generalization that can be made is: 2.The chirps occur closer together as the temperature increases.
Generalization is a statement you state after making an inference from an observation. For example, we can make a generalization by observing or analyzing the data from the experiment conducted which are given in the table.
From the table given, there seems to be a trend that can be observed. Temperature seems to influence the number of seconds between each chirp of the cricket.
A closer observation of the trend from the data given shows that in general, as the temperature was increased, the seconds between chirps seem to shorten.
Therefore, we make a generalization stating that: "2.The chirps occur closer together as the temperature increases."
