Explanation:
Atoms of A decay to atoms of B with a half-life of 200,000 years. If there are 20,000 atoms of A to begin with, how long will it take for there to be 2,500 atoms of A?
Answer:
The correct answer is: 600,000 years
Explanation:
Half-life is the time which is essential or required to decrease a specific substance to half of its initial amount of the substance. So, if a substance has a half-life of 200,000 years then it means it takes 200,000 years to decrease or change into a new substance and remain half of its initial quantity.
half-life amount
0 20000
1 10000
2 5000
3 2500
total half-life = 3 to 2500 atoms of A
so, the time will be = 3 * 200,000 years
= 6000000

Answer: C aka “the hydrosphere and the atmosphere interacts which affects the biosphere“
Explanation:
Hydro means water right... your welcome babes!!!
Spheres are the division of the air, land, water and living organism and their interactions. Interaction of hydrosphere with atmosphere affects the biosphere.
What are the types of the spheres and their relation?The spheres of the air and the constituents of the gases in the planet's surface is called the atmosphere and the water environment and its constituents are called hydrosphere. The sphere where the living organisms resides is called the biosphere.
The air and the air movement of the atmosphere along with the lake conditions or the hydrosphere affects the lives of the organism of the biosphere.
The fruits and the other vegetation is part of the biosphere and gets affected by the air from the atmosphere and the water cycle of the lake from the hydrosphere.
Therefore, option C. interaction of the hydrosphere and atmosphere affects the biosphere.

Consider the food chain grasshopper mouse snakes hawks. If snakes go extinct what will happen to the food chain
Answer:
This can actually cause a major problem if the number of grasshoppers were to increase out of control. They eat plants and the number of plants,which are the basis of the food chain, could severely decrease which would impact all of the levels operating above this trophic level.
Answer:
Lack of mice
Explanation:
If the grasshopper where to go extinct the mice population would decrease. Which would lead to it being harder for snakes to find food or they would begin to rely on a different food source. But the hawks would be able to find less snakes but would overall be fine.

We find DNA on the ___, In every living cell that an organism owns
a. chromosomes
b. reproduction
c. mitosis
Answer:
A. Chromosomes
Explanation:
A Chromosome is some thing carrying genetic information in the form of genes.
We find DNA on the chromosomes, in every living cell that an organism owns. So, the correct option is A.
What is Chromosome?The word chromosome comes from the Greek words for color (chroma) and body (soma). Chromosomes are so named because they are cell structures, or bodies, that are strongly stained by certain color dyes used in research.
Chromosomes are defined as structures found inside the nucleus of a cell that are organized into genes from proteins and DNA. Each cell normally has 23 pairs of chromosomes.
These are threadlike structures which are made of protein and a single molecule of DNA that serve to carry the genomic information from cell to cell.
Therefore, the correct option is A.

A 67-year-old was previously diagnosed with rheumatic heart disease. Tests now reveal lipoprotein deposition with chronic inflammation that impairs blood flow from the left ventricle into the aorta. Which diagnosis does this history support?
Answer:
Aortic stenosis
Explanation:
Aortic stenosis is one of the most common cardiovascular diseases. This disease is caused by the narrowing of the aortic valve opening, thereby restricting blood flow from the left ventricle to the aorta. Symptoms of aortic stenosis include, among others, heart palpitations, swollen feet, chest pain, breathing difficulties, sleeping difficulties, chronic fatigue, etc. Aortic stenosis may be cured by transcatheter aortic valve replacement, which is a minimally invasive surgical technique that allows to replace the narrowed aortic valve.

This was the question you asked earlier and you deleted it after i wrote a whole essay so here. I hope its still of some use.
Explanation:
I believe the most useful ap to use for people of age is Faceb00k. Faceb00k is a safe and friendly app where people can share what there doing or pictures.
So many parents and grandparents use this today to share photos of younger family members, and others can like and comment on there posts. Although their are some who receive hate, most of the people are quite rather friendly.
People like to share there appreciation for l0ved ones by letting the whole world see them through Faceb00k. Most elderly people do this so there younger ones can look back at all the memories they had together. Yes, its true they can just not post it and still look back at memories, but they post it because if it gets deleted and you posted the photos online there will always be a way to recover them.
In conclusion, this is why I believe Faceb00k is the best ap for the more elderly people. Firstly, they can show there memories to the world by showing appreciation. And lastly, whenever you post something online it can always be recovered, so those valuable moments will not be forever lost.

List and describe the different types of connective tissue. What similarities and differences did you observe?
Answer:
There are three types of connective tissues, loose connective tissues, dense, and hyaline.
Explanation:
The difference between them is the composition of the extracellular matrix that surrounds the fibroblast, that is to say that in loose connective tissue, the function will be of support or filling, and the fibroblast is immersed in an extracellular matrix with a high content of water and proteins. collagen.
On the other hand, in dense connective tissue, the amount of collagen fibers is greater, the protein structure as well, and the interlacing between proteins is more complex, and they may also have the ability to calcify as in the case of bone tissue or cartilage.
Finally, we have the hyaline connective tissue, which is very rich in hyaluronic acid and is found in the joints forming the discs, which are shock absorbers and protectors from bone wear due to friction between surfaces, hyaluronic acid, proteinglycans and glycoproteins are the main protagonists of all connective tissues together with the fibroblast, but even more so in the hyaline connective.
what makes stem cells different from cells in the body
Answer:
Stem cells are the body's raw materials
Explanation:
Stem cells are the body's raw materials — cells from which all other cells with specialized functions are generated. Under the right conditions in the body or a laboratory, stem cells divide to form more cells called daughter cells.
Stem cells are different from the other body cells as these are unspecialized cells which can undergo division and renew on their own. The stem cells can undergo specialization by the process of cellular differentiation.
What are Stem cells?Stem cells can be defined as the body's raw materials. These are the cells from which all the other cells with specialized functions are generated.
Embryonic stem cells are the pluripotent stem cells derived from the inner cell mass of a blastocyst. Blastocyst is an early-stage pre-implantation embryo. Human embryos reach the blastocyst stage in 4 to 5 days post fertilization, at which time they consist of 50 to 150 cells.
Stem cells are different from the other cells in the body in three ways which are the stem cells can divide and renew themselves over a long time. Stem cells are unspecialized cells, so they cannot do specific functions in the body unless they undergo cellular differentiation. Stem cells have the potential to become specialized cells, such as muscle cells, blood cells, and brain cells by undergoing cellular differentiation.

how did the settlers view panther when they came to north America
Answer:
They viewed the Panther with fear and set out on a mission to exterminate it.
Explanation:
The first Spanish conquistador to ever sight a Panther was Alvar Nunez Cabeza de Vaca in 1513. When he saw the panther which he referred to as a lion, he was fearful of the animal. He and other Europeans set out on a mission to exterminate all Panthers. This was also necessary as they had to clear the bushes for them to reside.
In 1821 when Florida officially became a part of the United States, and people had to relocate there, a $5 dollar bounty was placed on every Panther killed. The Panthers relocated farther into the wild. As of 1990, the population of the Panther was just around 50. Panthers have since been named an endangered species.
