Answer:
Organ System
Explanation:
A group of cells make a tissue.A group of tissues make an organOrgans combined together form an organ system.An organ system is made up of organs.
What are organ systems?An organ system is a biological system consisting of a group of organs that work together to perform one or more functions. Each organ has a specialized role in a plant or animal body, and is made up of distinct tissues.
Moreover, the 11 organ systems include the integumentary system, skeletal system, muscular system, lymphatic system, respiratory system, digestive system, nervous system, endocrine system, cardiovascular system, urinary system, and reproductive systems.
Hence, they are Integumentary System, Skeletal System, Muscular System, Nervous System, Endocrine System, Cardiovascular System, Lymphatic System, Respiratory System, Digestive System, Urinary System, and Reproductive System (Female and Male).

how does diffusion helps in absorption of minerals by roots????
Answer:
The soil water enters from the higher concentration to the lower concentration by the process of diffusion.
For a fictional neuron, the nernst potential of the mg2+ ion is +30 mv. given this information, where is the ion more highly concentrated? mg2+ is at a higher concentration inside the cell mg2+ is at a higher concentration outside the cell there is not enough information to determine the answer unanswered
From the nernst potential given, the mg2+ ion is at a higher concentration outside the cell.
What is nernst potential?
The potential across the cell membrane that exactly opposes net diffusion of a particular ion through the membrane.
The nernst potential of an ion is calculated as follows;
[tex]E = \frac{RT}{zF} ln[\frac{ion \ outside \ cell}{ion \ inside \ cell} ][/tex]
The given nernst potential of mg2+ ion is +30 mv = +0.03 V, (positive volt).
A positive log can only be obtained when the numerator (ion outside cell) is greater than the denominator (ion inside cell).
Thus, from the information given, the mg2+ ion is at a higher concentration outside the cell.

Fossil fuels such as gas, oil, and coal have what kind of energy?.
Answer:
chemical energy
Explanation:
The energy conversion goes from chemical energy stored in the fuels, to heat energy as it burns which is converted to kinetic energy as it drives large turbines and finally this is converted to electrical energy. The problem with burning fossil fuels is their effect on the environment.

I just need a description of what role bees play in pollination (it’s horticulture) btw
Answer:
Bees are essential for the growth of flowers and plants. They use the process of pollination where they transfer small grains of pollen from one flower of the same plant to another flower of the same species. This pollen transfer helps the flowers to get continuous growth.
Explanation:
Answer:
In the nature, plants reproduce s*exually but unlike many organisms, they do not directly mate with their opposite gender for reproduction. Their mechanism of reproduction in short is that male flowers produce pollens (yellow, powdery type thing) in thei anthers (male fower gamet) and when these pollens get contact with the female flower's stigma, the pollen fuses with the ovule and produces a fruit containing the seed.
Now how do we get these pollens moving from anthers to stigma? There are two ways. The first is by wind, when wind blows, it carries the lightweight pollens through the air and it falls onto a female flower.
the second one is by bees.
Those flowers produce nectar deep in the flower which can be sensed by bees. Bees enter the flower to collect the nectar while pollens are stuck on to its body. The bees travel to another flower for collecting nectar and when they do, the pollens from the body enter the stigma.
The water in vegetables evaporates over time causing the vegetables to wilt. Why do grocery stores spray water on their vegetables?.
Answer: For aesthetic reasons and to charge extra.
Explanation: Shoppers are more drawn to vegetables with water because they look more hydrated and “fresher”. Vegetables absorb moisture, so they will weigh more, therefore shops can charge more.

which type of drosophila probably changed the least over time?
The type of Drosophila that probably changed the least over time is the Drosophila melanogaster.
What do you mean by Drosophila?A Drosophila may be defined as a fruit fly that serves as one of the most important model organisms in the field of biological sciences due to its large chromosomes, high reproduction rate, and various varieties.
As compared to Drosophila willistoni, Drosophila equinoxialis, Drosophila equinoxialis caribbensis, etc. Drosophila melanogaster changed very least over time after analyzing its evolutionary pathway.
It is because it may consist of a large chromosome but a simple arrangement of genes, its well-specified segment polarity genes, pair-rule genes, and maternal effect genes.
Apart from this, it may also be because of less natural selection applied to Drosophila melanogaster.
Therefore, the type of Drosophila that probably changed the least over time is the Drosophila melanogaster.

What are the differences and similarities between cancer and an infectious disease? explain in detail.
Answer:
Cancer and infectious diseases are totally distinct categories of ailments. But at times they may present with similar symptoms and signs 1, 2. They are however treated with different modalities of therapy. Usually, infectious diseases do not carry the gloomy outlook of malignant tumors, although an infection may be fatal or develop at the end of treatment of a cancer.
Explanation:
We propose to disclose first degree analogous features between cancer and infectious diseases and to find out whether these similarities are superficial and negligible, due to the use of the same bodily pathways by the two categories of disease or if they represent significantly parallel characteristics. We have found several primary analogous features, predominantly regarding pathways of spread, but to some extent also concerning the interaction with the immune system. Some of the implications to our hypothesis are probably available in the recent literature, at the experimental or clinical levels. For example endostatin, an angiogenic inhibitor has been used to prevent promotion of metastasis in cancer and to reduce granulomas formation in schistosomiasis. An ECFR antagonist employed to restrain bronchial vessels proliferation in pseudomonas infection, has also been used for the treatment of lung cancer.

3. What do you think most public water is used for?
Answer:
The Earth might seem like it has abundant water, but in fact less than 1 percent is available for human use. The rest is either salt water found in oceans, fresh water frozen in the polar ice caps, or too inaccessible for practical usage. While population and demand on freshwater resources are increasing, supply will always remain constant. And although it's true that the water cycle continuously returns water to Earth, it is not always returned to the same place, or in the same quantity and quality.

Which statements is true about organ systems in the human body?
Choose 1 answer:
(A) if one organ system fails, a different organ system can take its place.
(B) all organ systems carry out the same functions in the human body.
(C) organ systems interact to allow the body to live and grow.
Answer:
(C) organ systems interact to allow the body to live and grow.
Explanation:
Organs depend on each other to carry out a certain function so the other organs can work.
Example- If the lungs of your body fails there will be no supply of oxygen. If there is no supply of oxygen there will not be enough blood for the heart to function.
If there is no oxygen there will be no oxygen or enough blood to flow to the brain.
Without the heart working the will be no blood to pump throughout the body.
Without the brain there will be no control to have the body and its organs to work properly.
Etc.
It is a chain reaction.
