CID is a neurological disease believed to be caused
by prions, pathogenic agents that are smaller than
viruses, and are extremely resistant to inactivation
by heat and disinfecting agents. The incubation
period can be many years long and death is almost
certain within a year after initial onset of symptoms. What is the Main Point and What is the sub points?
Answer:
Main point: CID is a lethal disease caused by prions.
Sub-points:
CID is a neurological disease (this means that it affects the nervous system.)Prions are pathogenic agents (this means disease-causing or harmful) that are smaller than viruses.They are resistant to inactivation by heat and disinfecting agents (this means that they're really hard to kill, because they're technically just misfolded proteins.)The incubation period can be many years long. (as in, symptoms may not show for a long period, but the prions are sitting in your body incubating and biding their time.)There's a very high mortality rate a year after symptoms show.You work for a zoo where you manage the breeding program for the cheetah. Your goal is to prevent inbreeding by obtaining mates from other zoos, making sure that your cats produce healthy offspring. In analyzing the genes of the cheetahs in all the zoo breeding programs, you notice very little variety of traits (alleles). Select all of the following conclusions which could be supported by your findings?
a. All of the zoo cheetahs come from just a few common ancestors.
b. The number of individual cheetahs currently in Zoos must be very low.
c. The variety of trats found in wild cheetahs is very narrow, possibly due to only a few of the animals surviving some event or series of events in thepast.
d. Even aner several generations, the baby cheetahs produced at your zoo wil show very ame geneto variaton.

What are characteristics of cheetah?Cheetahs are large cats that are known for their speed and agility. They have a distinctive appearance, with a slender body, small head, and long legs. They have a yellow-tan coat with black spots, and a long, bushy tail. They have a high flexibility and a unique skeletal structure that allows them to run at high speeds of up to 75 mph.
They have a unique tear-strip pattern on the face which helps to protect the eyes from the sun and dust while running at high speeds. They are also known for their endurance, and are able to maintain high speeds for longer periods of time than other big cats. They are carnivorous animals and mainly hunt small mammals, birds, and reptiles. They are also solitary animals, only coming together during mating season.

Scientists have recently discovered a new species that lives attached to the side of a tree. This organism
- is multicellular
- has vascular tissues
- has membrane bound organelles
The scientists put the organism in a sealed glass container filled with carbon dioxide and oxygen for several hours. Which of the following is evidence that this new species is an animal?
a
decrease in phosphate levels
b
decrease in nitrogen levels
c
increase in oxygen levels
d
increase in carbon dioxide levels
Answer:
D
Explanation:
Animals and plants preform a process known as cellular respiration.
This process is:
oxygen+glucose--> carbon dioxide+ water + ATP (energy)
If a plant was placed in this container with carbon dioxide and oxygen, it would preform cellular respiration, but it would also use another process called photosynthesis:
carbon dioxide+water+light energy-->oxygen+glucose
Since a plant performs both, the levels of carbon dioxide and oxygen wouldn't change a lot.
However, if this was an animal, the carbon dioxide levels would increase. An animal would inhale oxygen, use it in cellular respiration, and then exhale carbon dioxide as a waste product.
Therefore, the correct answer is D: increase in carbon dioxide levels.

Tectonic plate motion causes changes in the sizes, shapes, and the positions of the Earth's continents and oceans. Thus, the correct option is D.
What is Tectonic plate motion?Tectonic plates are the gigantic pieces of the Earth's crust and the uppermost mantle of the Earth. These layers of the earth are made up of oceanic crust and continental crust. Earthquakes mainly occurs around the mid-ocean ridges and the large faults which mark the edges of the plates in the Earth.
The heat from radioactive processes within the planet's interior causes these tectonic plates to move, which sometimes results towards and sometimes away from each other. This movement of the tectonic plates is called as plate motion or tectonic shift.
Therefore, the correct option is D.

Seif’s pet mouse had babies. Five of the babies were black and two were white. The father mouse was black. The mother mouse was white. Seif and his friends wondered why the mice were different colors.
These were their ideas:
Jerome: Baby mice inherit more traits from their fathers than their mothers.
Alexa: Te baby mice got half their traits from their father and half from their mother.
June: Male traits are stronger than female traits.
Seif: Black mice have more traits than white mice.
Fiona: The black baby mice are probably male and the white baby mice are probably female.
Lydia: Parent’s traits like fur color don’t matter—nature decides what something will look like.
Billy: Blood type determines what traits babies will have.
Which friend do you most agree with and why? Explain your thinking.
Answer:
Lydia
Explanation:
The black fur in mice is probably more the dominant-inherited trait. The white fur is probably a recessive gene so less of the baby mice will have white fur.
The characters of offspring is decided by their traits, which they get from their father and mother. Sefi's pet mice have different colors because it got half traits from mother and half from father.
What is genetic inheritance?Genetic inheritance means transfer of characters from parents to offspring. Due to this reason, offspring have characters from both father and mother.
This process is based on Mendalian principle. Any character of offspring is determined by both father and mother, not from the single one.
Here, as the father mouse was black and the mother mouse was white, so according to Mendalian principal, there were difference in the colors of baby mice.
Thus, one should be agree with Alexa, who gave an idea that the baby mice got half their traits from their father and half from their mother.

What are the similarities and differences between a predator-prey relationship and a herbivore-plant relationship?
Answer:
Predator-prey relationship and a herbivore-plant relationship have some of the similarities and some differences.
Similarities:
In both relationship, Predator-prey and a herbivore-plant, the interaction is between two species in which one organism or species fed over other organism. in predator-prey relationship, predator is the species that fed over prey and in herbivore-plant relationship, herbivores are the species that fed over plants. So, both are type of predation .In both relationship, one species dependent on other for their survival or food.Both relationship controls the size of recessive species such as prey and plants in the environment.Differences:
herbivore-plant has mutual interaction as herbivores eat plants and also helps plants to spread their seed and when animals die it decompose to the soil which is beneficial for plant growth while this is not same with predator-prey relationship, they have symbiotic relationship.In herbivore-plant relationship, the plants are unable to move in order to defend themselves except some mechanical advantages while in predator-prey relationship, prey can move themselves and fight for their survivalHence, predator-prey relationship and a herbivore-plant relationship have some similarities and differences as well.

When the CAU anticodon of a tRNAMet was modified to UAC, the anticodon for tRNAVal, valine aminoacyl-tRNA synthetase, recognized the altered tRNAMet and added valine rather than methionine to it. When the converse modification was made, the altered tRNAValcontaining a CAU anticodon (rather than UAC) was recognized and activated by methionine aminoacyl-tRNA synthetase. What do these data suggest about the mechanism by which aminoacyl-tRNA synthetases recognize their cognate tRNAs
Answer:
With the information obtained, it can be deduced that the tRNA anticodon region is recognized by an aminoacyl-tRNA synthetase, however some of these enzymes may have different elements in their structure and which would be the majority and which may trigger a fundamental role in the aminoacyl-tRNA synthetase recognition

What are two factors that determine an object's thermal energy?
Answer: MASS AND TEMPATURE
An object's thermal energy is dependent upon its temperature and mass. The higher the temperature of a given quantity of a substance, more is its thermal energy. Similarly, for the same temperature, higher mass of a substance will contain more thermal energy.
Explanation:
Two factors that determine an object's thermal energy are Mass and temperature.
Mass:
The mass of an object influences its thermal energy. The greater the mass of an object, the more thermal energy it possesses. This is because a larger mass contains a larger number of particles that are in motion, contributing to the overall thermal energy of the object.Temperature:
The temperature of an object is a measure of the average kinetic energy of its particles. The higher the temperature, the greater the average kinetic energy and thus the greater the thermal energy of the object. Temperature determines the intensity of the thermal energy and how vigorously the particles are moving.Thus, mass and temperature, play significant roles in determining the thermal energy of an object.
