Answer: Political map
Explanation:
Answer:
Political map

A political map is most likely to focus on boundary lines. Topographic, physical, and geologic maps may show boundaries, but these boundaries aren't usually the focus of the map.
What is an organism that lives on or in another organism and derives its nutrition from that organism?
Answer:
A parasite
Explanation:
Parasitism is a form of symbiosis where one organism lives on/in another organism, as in the question, and gets a benefit from that organism, while the other organism is harmed. This is denoted by +/-, which means that one is positively impacted and one is negatively impacted, as opposed to commensalism, which is +/0, or mutualism, which is +/+.
An example is tapeworms, which are flatworm parasites that live in the human intestine; they benefit while the host suffers.

Science Riddle of the Day: Whats The Most tiniest Virus Ever?
Answer:
The smallest viruses are thought to be the Porcine Circovirus.
Explanation:
A scientist set up an experimental ecosystem in a sealed room with no windows. The experimental ecosystem has plants, and animals that eat those plants. The scientist can control whether the room is light or dark with a light switch outside the room.
The amount of carbon in the air of the ecosystem started out low. Then the amount of carbon in the air started to increase. Is the increase because the scientist switched the light on or because she switched the light off? What happened to the number of energy storage molecules in the living things?
The scientist . . .
a
switched the light off, and the number of energy storage molecules in the living things decreased.
b
switched the light off, and the number of energy storage molecules in the living things increased.
c
switched the light on, and the number of energy storage molecules in the living things increased.
d
switched the light on, and the number of energy storage molecules in the living things decreased.
Answer:
Option-A
Explanation:
In the given question, the artificial ecosystem was prepared by the scientist which included the animals and plants. The light and dark conditions were controlled by a switch and bulb.
In the beginning, the amount of Carbon in the form of carbon dioxide was low due to the utilization of carbon dioxide by plants to perform photosynthesis. Then the amount of carbon dioxide increased in the atmosphere, the reason could be due to less consumption of carbon dioxide. The carbon dioxide is not uptake by plants during night conditions when photosynthesis process slowed down or stops.
Therefore, the dark condition was created by the scientist by switching off the lights and the number of energy molecule decreased as no photosynthesis was occurring.
Thus, Option-A is the correct answer.
Answer:
A
Explanation:
For both conditions, explain how protein synthesis contributes to the symptoms of the disease
Answer:
Explanation:
Among the causes of protein synthesis disorders, an important place is occupied by various types of alimentary insufficiency (complete or incomplete starvation, lack of essential amino acids in food, violation of a certain quantitative ratio between essential amino acids entering the body).
The protein synthesis correspondingly contributes to the symptoms of the disease by the fact that it produces some dysfunctional or bizarre proteins which significantly stimulate the specific types of disorder in organisms.
What is Protein synthesis?Protein synthesis may be defined as a biological process through which cells make protein in order to perform specific functions within the body of living organisms. It occurs in two stages, i.e. transcription and translation.
Transcription is the stage of protein synthesis through which the effective transfer of genetic instructions in DNA to mRNA in the nucleus takes place. While the process of translation involves the process by which a cell makes proteins using the genetic information carried in messenger RNA (mRNA). It occurs in the cytoplasm of the cell.
The disorder of protein synthesis is occupied by numerous kinds of alimentary insufficiency such as entire or incomplete starvation, insufficiency of mandatory amino acids in food, and violation of essential amino acids entering the body.

Why is the phloem in a leaf important to the roots of a plant?
A. It transports oxygen to the roots of the plant.
O B. It transports blastocysts to the roots of the plant.
O C. It transports water from the roots to the leaves.
OD. It transports carbohydrates to the roots.
Answer:
D. It transports carbohydrates to the roots.
Explanation:
Phloem is mainly used to transport nutrients from their region of production to the region that needs or stores the nutrient.
In photosynthesis, the method that plants make food, starch is produced. As the root hair cells needed energy to function, nutrients is needed so that it can respire and produce energy.
Therefore, when starch is produced, they will travel down the plants by the phloem to the roots where the nutrients is used.
brainlest please
As it delivers carbohydrates to the roots, the phloem in a leaf is vital to a plant's roots. So, the correct option is D.
What is Phloem?The plant tissue known as phloem is in charge of moving sugars, nutrients, and other organic substances from the leaves, where they are made by photosynthesis, to the other sections of the plant, such as the roots, flowers, and fruits.
Phloem has a bidirectional transport system that enables it to carry materials both across and down the plant. Sieve-tube elements and companion cells, which make up phloem tissue, are specialised cells.
A vascular tissue called phloem is in charge of moving sugars (carbohydrates) from the leaves to the roots and other sections of the plant. The plant may transfer the byproducts of photosynthesis through its whole system thanks to a process called as translocation.
Therefore, the correct option is D.

Global warming affects terrestrial ecosystems only because aquatic ecosystems are not affected by the Earth's surface temperature.
B)
All species can adjust to changes brought about by global warming through changing feeding and breeding patterns.
C)
Global warming concerns result from increase in the Earth's surface temperature and the increase in the carbon dioxide concentrations in the atmosphere.
D)
All of the above
Answer:
The answer is C
Explanation:
None of the others make sense
Global warming concerns result from increase in the Earth's surface temperature and the increase in the carbon dioxide concentrations in the atmosphere. So, the correct answer is (C).
What is Global Warming?
Global warming occurs when Carbon dioxide ([tex]CO_2[/tex]) and other air pollutants collect in the atmosphere. It is the long-term heating of Earth’s surface.
Due to Global warming, glaciers are melting, sea levels are rising, cloud forests are dying, and wildlife is scrambling to keep pace.
The causes of Global warming are so many like
1.Generating power
2.Manufacturing goods

The given statement "A nucleotide has 6 carbon sugars" is a false statement as nucleotides have pentose or 5- carbon ribose sugar in their composition.
A nucleotide is a compound that is connected to other nucleotides together to form structures of nucleic acids that are RNA and DNA. These compounds have three components linked together to form it, that are:
Nitrogenous basephosphate grouppentose sugar or 5-carbon sugarsIn DNA these pentose sugars are called deoxyribose and in RNA these pentose sugars are called ribose due to the presence of the -OH group on the 2' carbon of the ribose in RNA.

From the point of view of your immune system, what is the most likely consequence of picking your nose?
It can cause damage to the lining of your nose, which your immune system will then have to repair.
It removes the helper T cells stored in your nasal mucus, making your body less likely to produce a nonspecific immune response to pathogens.
It pushes any pathogens on your finger up into your nose and removes mucus that was there to trap them.
It can leave dirt inside your nose, which your immune system must remove by creating specific antibodies.

how could large molecules cross the cell mebrane
Answer:
When molecules are too large or too charged to cross the plasma membrane by diffusion or osmosis, there are other methods to accomplish their transport into or out of the cell. For example, some proteins in the plasma membrane are known as protein channels and they form a way for large or charged molecules to pass through the membrane.
