Which letter in the diagram below represents the location where blood is pumped to the lungs and picks up oxygen?

Answer: Without plants there would be no OXYGEN on earth. Plants take all the AIR we breathe and all the FOOD we eat. Plants take energy from the SUN and make their own food in the form of GLUCOSE. Plants take in CARBONDIOXIDE from the air, and give off OXYGEN.

Explanation:

Plants are autotrophs which means they are producers. Green plants are able to manufacture their own food through the process known as PHOTOSYNTHESIS.

This process, photosynthesis, is not only important to plants themselves but also to animals and humans, which depends on the products which is oxygen and glucose (food).

The main features of photosynthesis includes:

--> photosynthesis takes place in the chloroplasts of plant cells, in the presence of SUN ( solar energy).

--> The raw materials of the process are the low - energy containing inorganic compounds, for example, the CARBONDIOXIDE and water.

--> The final products of the process are high energy containing sugars (GLUCOSE). Oxygen is given off as a waste product which makes up the AIR we breathe.

--> The energy needed to drive this anabolic process comes from the sunlight absorbed by chlorophyll, the green pigment found in chloroplasts. While the glucose produced are converted to starch and stored in the plant storage organs such as roots, stems, fruits and seeds.

Answer: B. Some of the energy in the system has moved from one organism to another during the three months.

Explanation:

Option A is incorrect as the biomass of plant life will be greater than that of animal life since plants are considered to be primary producers.

Option C is incorrect as the air in the glass box contains carbon dioxide which is necessary to synthesize glucose.

Option D is incorrect as energy has entered the glass box since it's in a sunny location which gives it energy from the sun.

The correct option is B "Some of the energy in the system has moved from one organism to another during the three months".

The adaptive features of Earthworm include streamlined body with no antennae or arms. The body of this organism is divided into segments.

Adaptation can be defined as a state of the physical or the behavioral characteristics of an organism which helps them to survive better in the surrounding environment. Adaptation is essential for the survival of  organisms in the new environment. These adaptations help the characteristics to become a part of the genetic makeup of the organisms.

An earthworm is a streamlined body organism with no antennae or fins or any arms or legs. The streamlined shape of the body is an adaptation to living in the narrow burrows which are present underground and the need to move easily through the soil. An earthworm has circular muscles which surround each body segment in the organism.

Answer:

Where a star ends up at the end of its life depends on the mass it was born with. Stars that have a lot of mass may end their lives as black holes or neutron stars. A low or medium mass star (with mass less than about 8 times the mass of our Sun) will become a white dwarf.

The initial mass of the star with which it was born will determine how the star will end its life cycle.

Black holes are regions in space with an extremely high pull of gravitational force which cannot even be escaped by light. Black holes are formed when the central core of a dying star collapses in itself.

Neutron stars on the other hand are extremely dense dead stars. Neutron stars are extremely bright objects, unlike black holes. Black holes are extremely dark because they trap any surrounding light while neutron stars emit light.

The massive stars in the universe end up as neutron stars or black holes. A star that has a low or medium mass ends up as a white dwarf.

A white dwarf is a dying star with a mass comparable to the mass of our sun but a size comparable to the size of the earth. Thus they have high mass and low dimensions.

Therefore, the factor that determines what a star will end up as is its mass when it was born.

Answer:

I believe the answer is A: disease

Answer:

1) The Greenhouse Effect works When the Sun's energy reaches the Earth's atmosphere, Some of it is reflected in space, and the rest is absorbed and re-radiated by the greenhouse gases.

2) The greenhouse effect is the trapping of heat under the atmosphere, which is a natural effect caused by greenhouse gases. However, when greenhouse gas concentrations are too high, they trap too much heat and increase the temperature on Earth, causing the enhanced greenhouse effect.

Explanation:

Climate change is real truth on the earth. because the climate change is necessary for all living organisms and plants in different regions.

Overlying, adjacent plates are pulled apart when magma convection currents flow away from one another.

Magma is the molten rock below the crust, in the mantle. Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth's crust.

As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor. Eventually, the crust cracks.Hence, option E is correct.

Answer:

Circadian rhythms.

Explanation:

Stimulus in biology can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal). All living organisms (both plants and animals) respond to changes in their environment and as such an appropriate reaction or response is made. Also, stimulus arising from within the organism is known as internal stimulus while those from its environment are known as the external stimulus.

In organisms, the specialized cells that detect stimulus are generally known as sensory receptors while a group of these receptors is referred to as sense organ.

Since both plants and animals respond to environmental stimuli, it simply means that, these living organisms have physiological cycles referred to as circadian rhythms.

Circadian rhythms is a natural internal process that controls the physical, mental, and behavioral changes in living organisms such as the sleep-wake cycle. The circadian rhythm is simply the internal body "24 hour" clock.

For example, there are large changes in the activities that happens with respect to the organs such as kidney, liver and endocrine glands within the body of living organisms throughout the day. Also, they experience timely shift in blood pressure, amino acid levels, body temperature, metabolism, etc.

Hence, living organisms are usually more energetic and at alert when the aforementioned activities and others are at their highest point once a day as a result of circadian rhythms.

Prevailing winds and positions of islands cause warm ocean currents to pass Christchurch in normal years for the following reasons:

Warm ocean currents are typically driven by prevailing winds, oceanic currents, and other factors such as the shape of coastlines and the positions of islands.

Note: That oceanic currents and winds can be affected by a range of factors, including El Niño and La Niña events, which can cause changes in sea surface temperatures and alter the path of ocean currents. As a result, there may be some years when warm ocean currents do reach Christchurch, even if this isn't typically the case in normal years.

Answer:

On the basis of similarities and differences.

Explanation:

We can classify the organisms on the basis of similarities and differences. There are five kingdoms i.e. Protista, Fungi, Monera, plantae and Animalia. Each kingdom has some unique characteristics so the organisms in the chart will be seen to which kingdom it belongs to see the similarities with them. If the organism is unicellular and eukaryotic organisms so it is placed in kingdom Protista, if the organism is plant like and having chlorophyll so it is placed in kingdom plantae and if the organism has the ability to move from place to place and heterotroph we can place it in kingdom Animalia.
