pls help !!!!!!!!!!!

Answer:

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.

The light-dependent reaction

          The light-dependent reaction, as its name implies, occurs inside the thylakoid membrane and necessitates a constant supply of sunshine. The light waves' energy is captured by the chlorophyll and transformed into chemical energy in the form of the molecules ATP and NADPH.

What is Photosynthesis ?

           Plants and other living things employ a process called photosynthesis to transform light energy into chemical energy that can then be released through cellular respiration to power the organism's activities. Despite the fact that various species undertake photosynthesis in different ways, the process always starts when proteins called reaction centres that contain green chlorophyll absorb energy from light. Unlike bacteria, which have these proteins incorporated in the plasma membrane, plants store these proteins in organelles called chloroplasts, which are most prevalent in leaf cells.

         When the cell needs energy, ATP can be taken out and used to fuel processes or stored for use in later ones. Animals use ATP to retain the energy released during meal digestion. Similar to this, plants use ATP molecules to store the energy they obtain from light during photosynthesis.

          In addition to converting ADP to ATP, photosynthetic processes are used by plants to absorb, process, and store solar energy. Animals convert ADP to ATP, which can subsequently be utilised to drive essential development and cell maintenance, using the energy supplied from the breakdown of glucose and other molecules.

           Plants absorb water (H2O) and carbon dioxide (CO2) from the soil and atmosphere during photosynthesis. Water is oxidised, which means it loses electrons, while carbon dioxide is reduced, which means it receives electrons, inside the plant cell. Water is converted into oxygen and carbon dioxide into glucose as a result.

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.

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.

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.

Melanocytes

Explanation:

Melanocytes produce the protective skin-darkening pigment melanin. Melanocyte, specialized skin cell that produces the protective skin-darkening pigment melanin. Birds and mammals possess these pigment cells, which are found mainly in the epidermis, though they occur elsewhere like in the matrix of the hair.

Melanin is a that is produced in organelles called in specialized cells called

Melanin is a dark pigment that is found in the skin of a human. This factor affects the color of the eyes, hair, etc in people as the more melanin available in the body, the darker these parts of the body are.

A specialized cell is responsible for the production of melanin called melanosomes and this is in varying quantities in different people.

Melanosomes are those cell nucleus that are responsible for the production, storage and transfer of melanin to the parts of the body.

Therefore, the correct answer is melanosomes

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.

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.

The acclimation of a persons body to the low oxygen atmosphere at high altitudes

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

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.

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.
