true or false ?

the oxygen level inhaled air is 5% greater than exhaled hair because our body cells have not used any oxygen yet

Answer:

Yes.

Explanation:

Yes, the statement is right because in chemical war, great damage occurs to all living organisms that has a bad effect on our environment. These chemicals are very dangerous so its usage in the war has long term effects on the environment and the organisms that live in it. Both the opponents receive great damage from this chemical war and the destruction of the natural beauty of the place vanished where this war occurs so this vanished of beauty and organisms is the defeat of both the opponents that fought this war.

2. Plants grow towards the light. Plant leaves bud and seeds germinate when the temperature is right. Their roots and stems grow in certain directions in response to the pull of gravity.

Explanation:

Answer:

a) For example, a cat may see a saucer of milk. Information from

the cat’s eyes travels along nerve cells to the brain, where the brain

processes the information. If the brain decides it wants the milk,

the brain sends a signal to the muscles in the cat’s limbs, and the cat

moves to the saucer of milk and drinks it

Explanation:

b)  For example,

specialized cells in the leaves of trees detect the decrease in sunlight

as winter approaches. Chloroplasts then reduce production of green

chlorophyll. As existing chlorophyll is broken down, other coloured

particles are revealed, creating the beautiful red- and orange-coloured

leaves we see during autumn. Th e leaves eventually die and fall off . In

the spring, increased sunlight and warmer temperatures promote the

production of new leaves containing large amounts of chlorophyll, and

the green colour returns to the leaves.

Answer:

The Temperature rises as carbon dioxide levels rise. The temperature decreases when the carbon dioxide concentration falls.

Explanation:

A tiny part of the correlation is attributable to the relationship between temperature and carbon dioxide solubility in the surface of the ocean, but most of it is consistent with feedback from carbon dioxide to the environment. These changes are expected to be consistent with Earth's radiative balances and the function of greenhouse gases in climate change. While determining the cause and impact, initially or by some other method, between carbon dioxide and climate, may appear straightforward, it still is extremely difficult to find the cause and effect. Other changes include altered vegetation, earth surface properties, and ice-sheet extent in the glacial climate.

Other paleoclimate representatives allow us to comprehend the role of the oceans in climate change in the past and future. The ocean holds 60 times as much carbon as the atmosphere, and the change in carbon dioxide in the atmosphere is predicted throughout the past several hundred thousand years to be compared to carbon changes in the ocean. While oceans vary far more slowly than the atmosphere, in past CO2 fluctuations the ocean has played a key role and will play a part for millennia in the future.

Finally, paleoclimate data demonstrate that there is not only temperature about climate change. In the past, many other aspects of the climate have altered as carbon dioxide has changed. The snow was lower, the continents dried and the tropical mousses weaker during the glacial ages. Some of these changes may be independent; others may be closely associated with changing carbon dioxide levels. A thoroughness of research is to understand what these changes might occur in the future and how substantial these changes may be.. The Paleoclimatology Program of the NOAA provides scientists with a documentation of previous changes as an approach to understanding future climate change.

Answer:

Population of mice having dark coat colors decreases by changing of features of natural selection.

Explanation:

The population of mice having dark coat colors decreases if the field has light colour due to drought conditions because they are vulnerable to their predators and natural selection. In green field, dark colour mice can't be seen by the predators that will leads to increase their population while on the other hand, if there is drought condition it will leads to increase the population of light colour mice because they can't be seen by predators and decreases the population of dark colour mice due to vulnerability to their predators. Food type availability to the organisms due to environmental conditions lead to natural selection of that organisms which can feed on that food type.

Answer:

Ocean water moves in predictable ways along the ocean surface. Surface currents can flow for thousands of kilometers and can reach depths of hundreds of meters. These surface currents do not depend on weather; they remain unchanged even in large storms because they depend on factors that do not change.

Surface currents are created by three things:

global wind patterns

the rotation of the Earth

the shape of the ocean basins

Surface currents are extremely important because they distribute heat around the planet and are a major factor influencing climate around the globe.

Answer:

The Coriolis effect causes winds and currents to form circular patterns.

Answer:

pyruvic acid

Explanation:

Glycolysis involves the breaking of glucose molecule into two molecules of a 3-carbon compound called pyruvate (pyruvic acid) & two other molecules of ATP

Through a sequence of processes known as glycolysis, glucose is divided into two pyruvate molecules, each of which has three carbons. Thus, option C is correct.

Glycolysis is the metabolic process by which glucose produces cellular energy, glycolysis is significant.

The most crucial source of energy for all living things is glucose. Most cells in the human body prefer glucose as a fuel because red blood cells cannot use anything else.

Most living things engage in some form of glycolysis. It represents the initial phase of cellular respiration.

It is a glycolysis route that results in the partial conversion of pyruvate from glucose. The common mechanism for both aerobic and anaerobic respiration is glycolysis.

Therefore, pyruvic acid is a 3-carbon molecule which is the final products of glycolysis.

When water increases in volume, it becomes less dense. As water cools, it contracts and decreases in volume. When water decreases in volume, it becomes more dense. For samples of water that have the same mass, warmer water is less dense and colder water is more dense.Im not sure if this helps but try it out :)

Archaebacteria and eubacteria. Eubacteria are more common on earth while the archeabacteria are not despite their existence in harsh environment they have been found in human digestive system in the gut

kingdoms of bacteria are more similar to humans are archaebacteria and both are in symbiotic association as well. Kingdom archaebacteria both are the descendants  species.

The bacteria which are the species which developed differently from the group of blue green algae and totally evolved differently.

Archaebacteria are the species with tRNA and absence of cell walls. These are the species with the extreme adaptations.

Halophiles are the species which are present in the salty areas, methanogens present in the marshy areas, thermophiles present in the most hot temperatures.

The kind of adaptation shows the extreme advancements along with the special structures present for the survival.

Archaebacteria are in symbiotic association where these show the relation between human gut and these are present in the intestinal areas of human body.

Therefore both are descendants and thus very similar to each other along with the symbiotic association to each other.

Explanation:

Photosynthesis occurs in two stages. In the first stage, light-dependent reactions or light reactions capture the energy of light and use it to make the energy-storage molecules ATP and NADPH. During the second stage, the light-independent reactions use these products to capture and reduce carbon dioxide.

Answer:

This new model may better explain the elements required for photosynthesis to occur. Sunlight, water, and carbon dioxide are required for the plant to produce its own food. Someone who is unfamiliar with the process of photosynthesis must begin with the basics and then build on this knowledge.

Answer:

The high sugar content caused too much water to move out of the root cells.

Explanation:

Too much causes transpiration to occur, in this case too much water killed the plant.

The statement which explains why the plant in Group E and F died is that the high sugar content caused too much water to move out of the root cells.

High sugar content in plants may be defined as the amount of carbohydrates (glucose) and their components get accumulated in the different parts of the plants in a high ratio. It also affects the rate of photosynthesis.

High sugar content leads to the loss of water (transpiration) in plants. In this condition, water loss is maximum which results in the scarcity of water in the root cells. And hence the plant died.

Therefore, the statement which explains why the plant in Group E and F died is that the high sugar content caused too much water to move out of the root cells.

Answer:

D) a shift in earth’s orbit

Explanation:

^^^^^^^^^

A shift in Earth's orbit caused global cooling during the Pleistocene. This period, which began around 2.6 million years ago and lasted until about 11,700 years ago, was marked by a series of glacial cycles, with ice sheets advancing and retreating across much of the Northern Hemisphere. Hence the correct option is D.

Global cooling refers to a long-term trend of decreasing temperatures across the Earth's surface and atmosphere over an extended period of time. This can lead to changes in climate patterns, including changes in precipitation, sea levels, and weather events.

Global cooling can occur due to a variety of factors, such as changes in solar radiation, volcanic activity, or shifts in the Earth's orbit. In recent decades, global warming has been the predominant trend, with temperatures rising due to human activities such as the burning of fossil fuels and deforestation.

The cooling is thought to have been caused by changes in Earth's orbit, including changes in the tilt and orientation of its axis, as well as variations in its elliptical path around the sun. These changes affected the distribution of sunlight and solar radiation across the planet, leading to cooler temperatures and the growth of ice sheets.
