Answer:
Alzheimer's disease is a neurodegenerative disease that usually starts slowly and progressively worsens. It is the cause of 60–70% of cases of dementia. Gradually, bodily functions are lost, ultimately leading to death. The cause of Alzheimer's disease is poorly understood. Other risk factors include a history of head injury, clinical depression, and high blood pressure. Initial symptoms are often mistaken for normal aging. Exercise programs may be beneficial with respect to activities of daily living and can potentially improve outcomes. Behavioral problems or psychosis due to dementia are often treated with antipsychotics, but this is not usually recommended, as there is little benefit and an increased risk of early death.
Explanation:
The course of Alzheimer's is generally described in three stages, with a progressive pattern of cognitive and functional impairment. Detailed neuropsychological testing can reveal mild cognitive difficulties up to eight years before a person fulfills the clinical criteria for diagnosis of Alzheimer's disease. These early symptoms can affect the most complex activities of daily living. The most noticeable deficit is short term memory loss, which shows up as difficulty in remembering recently learned facts and inability to acquire new information. Subtle problems with the executive functions of attentiveness, planning, flexibility, and abstract thinking, or impairments in semantic memory can also be symptomatic of the early stages of Alzheimer's disease.

Why do the neuron and epithelial cell look so different?
They have a different function in the body.
A different section of DNA is activated in the nucleus.
They were created from different parent cells.
A different tissue results from a collection of each type of cell.
More time was spent creating the neuron.
Answer:
Nerve cell shapes vary according to the number, branching and disposition of their projections or dendrites, collectively known as arborization. This determines their capacity for interacting with their environment and with other nerve cells or neurons, hence their computational ability and roles.

What structure in the female reproductive system produces eggs?
Vagina
Ovary
Fallopian tube
Cervix
Ovary structure in the female reproductive system produces eggs. Thus, the correct option is B.
What is female reproductive system?The uterus, fallopian tubes, ovaries, and the vagina are a woman's internal reproductive organs. The muscular, hollow tube known as the vagina connects the uterus to the vaginal opening. The muscular walls of the vagina allow it to expand and contract.
The primary roles of the female reproductive system are to produce eggs (ova) that can be fertilized and to create the environments and space necessary for a baby to grow. The female reproductive system also possesses the components required for a man's sperm to interact with a woman's ova in order for this to occur.

how can you survive a very cold winter
Answer:
Prepare! Follow our winter survival kit checklist for tips on proper clothing, winter car kits, home supplies, and more.
Hypothermia and frostbite are the real dangers. Even in 50 F temperatures, you’re at risk of losing too much core and limb heat.
Protect your body heat. Protect it, trap it, and treat it like the precious resource it is.
Keep covered. Wind and exposure are the enemy. Exposed skin accelerates heat loss, especially through wind.
Dress in layers. The air trapped between each layer holds your body heat, like your own personal hot tub. Plus, layers give you better control over regulating body heat so you can avoid dangerous sweating.
Avoid sweating and stay dry. Besides moisture loss, sweating is bad because water on your skin makes you colder. That’s why we sweat to begin with — it’s the body’s air conditioning system.
Snow is an insulator. Don’t be afraid to use it for shelter.
Avoid eating snow. You lose a lot of core heat by melting snow inside your body. Melt it outside your body instead.
Alcohol does not warm you. Sorry, Russia!
Hydrate. Severe cold can be just as dangerous as severe heat. Stay hydrated.
Don’t travel unless you have to. Conserve energy. Stay where you’re most likely to be found. Especially if you’re in a nasty storm where navigation and shelter is difficult.

Can someone explain how the process of bioaccumulation happens?? ‼️10 points‼️
Answer:
Bioaccumulation is the process by which toxins enter the food web by building up in individual organisms, while biomagnification is the process by which toxins are passed from one trophic level to the next (and thereby increase in concentration) within a food web.

The illustration shows a sequence of bases on one strand of a DNA molecule. Use the illustration below to answer the next three questions.
How many amino acids are coded for by the sequence on side A of this DNA strand?
What is the order of bases on side B, from left to right?
If G replaced A as the first base on side A, what would the order of bases be on side B of this DNA strand?
The diagram is lacking but the number of amino acids can be calculated by having into account that three nucleotides produce a codon. It is the genetic code.
What is the genetic code?The genetic code makes reference to the linear order of nucleotide bases in a given DNA strand.
This linear order is fundamental to produce a particular mRNA, which is used as a template during translation.
When occurs a substitution (mutation) of a nucleotide base for another in a DNA strand, then the genetic code can be used to determine the amino acid that will be added to this new codon.

Chloe reads that given the correct conditions, cuttings from certain plants will form roots along the stem, enabling a new plant— identical to the parent plant—to grow. Chloe wants to investigate whether rooting hormone is beneficial or detrimental in this process. She takes cuttings from a shrub. For Group 1, she places some shrub cuttings in potting soil in partial shade. For Group 2, she dips some shrub cuttings in rooting hormone, places them in potting soil, covers them with a clear dome, and places them in direct sunlight. She waters the groups equally. She pulls up some cuttings after 3 days and again after 6 and 9 days to observe and measure root growth. Write a hypothesis for Chloe's experiment.
Answer:
The correct answer is - If you use the rooting hormone when cloning plants from cuttings, then it will be beneficial for the cuttings.
Explanation:
A hypothesis is a possible explanation or solution behind the particular natural world process or phenomenon. It is formed on the basis of the observation of the phenomenon or process, how it works or what characteristics it shows.
In this study, it is found that the root hormones promote the growth in the clonings from the cuttings of plants thus, the provided hypothesis is the correct hypothesis for the experiment given.

Answer:
The second one
Explanation:
The formula to calculate force is:
F=m*a
So, 500 kg*10 m/s= 5000 N
The reason why it is not the last one is because we are looking for force, which is measured in Newton's.
