Answer:
Alzheimer's disease.
Explanation:
It is A progressive disease that destroys memory and other important mental functions.
Brain cell connections and the cells themselves degenerate and die, eventually destroying memory and other important mental functions.
Symptoms :
Cognitive: mental decline, difficulty thinking and understanding, confusion in the evening hours, delusion, disorientation, forgetfulness, making things up, mental confusion, difficulty concentrating, inability to create new memories, inability to do simple maths, or inability to recognise common things
Behavioural: aggression, agitation, difficulty with self care, irritability, meaningless repetition of own words, personality changes, restlessness, lack of restraint, or wandering and getting lost
Mood: anger, apathy, general discontent, loneliness, or mood swings
Psychological: depression, hallucination, or paranoia
Also common: appetite loss, difficulty with skilled movement, or paraphasia
there is no cure for Alzheimer's disease or a way to stop or slow its progression, there are drug and non-drug options that may help treat symptoms.
Cause:
Alzheimer's disease is thought to be caused by the abnormal build-up of proteins in and around brain cells.
I chosed it because it is very common
Over 1.5 million people come up with this disease

Epinephrine initiates a signal transduction pathway that involves the production of cyclic AMP (cAMP) and leads to the breakdown of glycogen to glucose, a major source of energy for cells. But glycogen breakdown is only part of the fight-or-flight response that epinephrine brings about; the overall effect on the body includes increased heart rate and alertness, as well as a burst of energy. Given that caffeine blocks the activity of cAMP phosphodiesterase, propose a mechanism by which caffeine ingestion leads to heightened alertness and sleeplessness.

Which of the following is necessary for a geothermal plant to function?
Your answer:
biomass
fossil fuels
heated rock
hydrogen
sunlight
Answer:
Geothermal power plants use hot water to generate steam to turn a turbine for electricity generation. Since the heat of the water is the essential component of a geothermal power plant, these active systems are typically located where hydrothermal reservoirs exist.

Fresh steak is said to have both negative and positive redox potential. Discuss how the redox potential affects the microbial ecology of the food
Answer:
Increases redox potential decreases microbial growth inside food.
Explanation:
The redox potential is considered as one of the most complex indicators of the physical conditions of microbial cultures. The measurement of redox potential could be very useful for the determination of qualitative and quantitative parts of the microbial contamination. During the bacterial growth, the redox potential of the medium decreases. Redox potential is a measure of the tendency of a biological species which can be acquire or lose electrons through ionization. If the redox potential of the medium is increases, there will be lower growth of microbes in the food and vice versa.

An increase in biodiversity result in
A. More competition for abiotic factors
B. Less competition for biotic factors
C. An increase in the sustainability of an ecosystem
D. A decrease in the sustainability of an ecosystem
Answer:
The correct answer is - C. An increase in the sustainability of an ecosystem.
Explanation:
Biodiversity is the variety of different biological species and populations on the earth or in an ecosystem. Biodiversity helps in maintaining health by providing food and other resources. Higher biodiversity healthier the earth.
Sustainability is the ability to maintain the ecological process and its structure and function in case of external stress for a longer time. The more sustainability of an ecosystem the healthier the ecosystem. The biodiversity of an ecosystem provides sustainability to the ecosystem. An increase in biodiversity will lead to a more sustainable ecosystem.
Can someone help me with the order of the carbon cycle ?
Answer:
First what is it? Carbon cycle is, nature's way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms.
1.Carbon moves from the atmosphere to plants. In the atmosphere, carbon is attached to oxygen in a gas called carbon dioxide (CO2). Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth.
2.Carbon moves from plants to animals. Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too.
3.Carbon moves from plants and animals to soils. When plants and animals die, their bodies, wood and leaves decays bringing the carbon into the ground. Some is buried and will become fossil fuels in millions and millions of years.
4.Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants need to get rid of carbon dioxide gas through a process called respiration.
5.Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas. Each year, five and a half billion tons of carbon is released by burning fossil fuels. Of this massive amount, 3.3 billion tons stays in the atmosphere. Most of the remainder becomes dissolved in seawater.
6.Carbon moves from the atmosphere to the oceans. The oceans, and other bodies of water, absorb some carbon from the atmosphere. The carbon is dissolved into the water.

Which of the following are shown in karyotypes?
a
sex chromosomes
b
homologous chromosomes
c
autosomes
d
all of the above
Answer:
Karyotypes describe the chromosome count of an organism and what these chromosomes look like under a light microscope. Attention is paid to their length, the position of the centromeres, banding pattern, any differences between the sex chromosomes, and any other physical characteristics.
Explanation:
As this karyotype displays, a diploid human cell contains 22 pairs of homologous chromosomes and 2 sex chromosomes. ... The maternal and paternal chromosomes in a homologous pair have the same genes at the same locus, but possibly different alleles.
