Cyanobacteria are important to the evolution and advancements of other life forms on Earth because they: B. produced oxygen from photosynthesis.

Cyanobacteria is scientifically referred to as Cyanophyta and it can be defined as a group of single-celled, prokaryotic photosynthetic bacteria that live in aquatic habitats (water) and moist soils.

Additionally, this division of microorganisms are capable of manufacturing their own food through a process known as photosynthesis, which typically leads to a release of oxygen into the ecosystem.

In conclusion, Cyanobacteria are very important to the evolution and advancements of other life forms on planet Earth because they help in the production of oxygen through photosynthesis.

Answer:

The easiest one to correct would most likely be Class V, since in this type of mutation, the only problem or abnormality is the production of insufficient amounts of the needed CFTR.

Explanation:

Mutation Classes

Class I - Gene contains a stop signal that prevents CFTR from being made.

Class II - CFTR is made, but does not reach the cell membrane

Class III - CFTR is made and in the right place, but does not function normally

Class IV - Channel does not move substances efficiently or at all

Class V - CFTR is made in smaller than normal quantities

herbivore

Explanation:

the word herbivore contains the word "herb" meaning plants

Answer:

Explanation:

Oxygen is needed to support life and some metabolic processes in microorganisms especially aerobic organism.

The presence of oxygen in the container gives them the opportunity to carry out there metabolic activities thereby enhancing there growth and multiplication.

Hence, to limit the growth of aerobic bacteria or fungi, and also to prevent the evaporation of volatile components that is available in the content oxygen is withdrawn this help extend the shelf life of the produce to be stored.

Answer:

Forensic anthropologist

Explanation:

Forensics is a branch of science that deals with the solving of crimes. According to this question, police are investigating a series of murders in which the suspect is leaving little to no physical evidence such as DNA or fingerprint. However, strange pieces of typewritten poetry was found tucked into the victims’ pockets as evidence.

Based on this evidence found, a FORENSIC ANTHROPOLOGIST is the person that can give valuable insight to help the police identify the perpetrator and possible future victims. This is because ANTHROPOLOGY is a social science subject that deals with past events, hence, forensic anthropologists will be able to work on the typewritten poetry.

A jar placed in a sunny window will get warmest if it is wrapped loosely in Black paper. So, the correct option is (G)

Sunny weather is described as the type of weather where the sky is blue, the grass is bright, and there is a lot of sunlight that is usually warm when the sun comes out, so people in cold climates find it quite looks nice. People may not be so fond of this weather.

When it comes to absorbing heat on sunny days, the color of the fabric is more important than the length or material it is made of, when compared to a black shirt with short sleeves, a long sleeve white shirt can make you feel colder because of all the colors.

So when we wrap a black paper on something like jar it will get warmer as compared to other colour papers.

Thus, a jar placed in a sunny window will get warmest if it is wrapped loosely in Black paper. So, the correct option is (G)

Answer:

The thermal energy of the Earth remains from its formation and is continuously generated from radioactive decay of long-lived radionuclides in the Earths interior. The deeper the Earth layers the higher the temperature with the geothermal gradient of temperatures through the Earth’s crust on average as high as 25–30°C/km.

Explanation:

The thermal energy affect the earth's layers by forming a thermal gradient.

Thermal energy of the Earth:

Deep inside the earth the thermal energy is generated by the radioactive decay of long-lived radionuclides.

This creates a thermal gradient from core to surface of the earth. The temperature of the core is highest, then the manle is semi-solid or liquid.

The crust of the earth is solid and have relatively less temperature,

Therefore, the thermal energy affect the earth's layers by forming a thermal gradient.

3. Fighting Disease --> IgA prevents the buildup of viruses and bacteria in the gut.

4. regulating chemical reactions --> Pepsin works in the stomach to speed up the breakdown of food.

Answer:

Explanation:

The burning of fossil fuels releases greenhouse gases into the atmosphere, increasing levels of CO2 and other gasses, trapping heat, and contributing to global climate change. Coal combustion releases the greenhouse gases carbon dioxide (CO2) and nitrous oxide (N2O) during combustion. The major disadvantage of coal is its negative impact on the environment. Coal-burning energy plants are a major source of air pollution and greenhouse gas emissions. In addition to carbon monoxide and heavy metals like mercury, the use of coal releases sulfur dioxide, a harmful substance linked to acid rain.

Answer:

Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.

Answer:

Osmosis or diffusion.

Osmosis if the movement is of water, and diffusion if gases

Answer:

rickettsia and viruses

Explanation:

This is because obligate intracellular parasite are parasite that affect humans and they grow, reproduce and survive inside the host cell. These parasite cannot live or survive outside host cell but they live inside host cell, replicate and they depend on the host cell resources i.e the use host cell resources thereby causing harm on the host cell. rickettsia and viruses are parasite that can only survive inside a living organism.

Answer:

rickettsia and viruses

Answer:

1.Plant absorbing water from the soil.

Explanation:

Osmomsis occurs by the movement of a water from a region of higher concentration of water molecules to a region of lower concentration of water molecules, through a semi permeable membrane,

OR

It occurs as a result of movement of substance molecules from a region of lower concentration to a region of Higher concentration of the substance.

Note: The higher the concentration of the substance molecules,the lower the concentration of water molecules.

The movement of water into the roots of the plants from the soil demonstrates the most valid and accurate example of osmosis. Thus, the correct option for this question is A.

Osmosis may be defined as a type of process through which the movement of a solvent such as water takes place from a region of lower solute concentration to a region of higher solute concentration through a semi-permeable membrane.

The absorption of sugar into the blood from the gut is mediated by secondary active transport with the help of transporters like SGLT-1 and SGLT-2. The process through which water is evaporating from a leaf is known as transpiration. The process of entering oxygen into the blood from the lungs is known as diffusion.

Therefore, the movement of water into the roots of the plants from the soil demonstrates the most valid and accurate example of osmosis. Thus, the correct option for this question is A.
