As the carbon dioxide level rises, the temperature rises whereas  When the carbon dioxide level decreases, the temperature decreases.

As there is a direct relationship between carbon dioxide and temperature about millions of years past, it is difficult to deduce future changes to the Earth's climate. For example, at the end of the last ice age atmospheric carbon dioxide level increased by 50% while global temperatures raised by 4 Celsius.

Human Activity is the main reason for increased Greenhouse gas levels. Over the last century, the burning of fossil fuels such as coal and oil has increased the levels of carbon dioxide. This increase happens because the oil-burning process combines carbon with oxygen in the air which makes carbon dioxide.

So it can be conclude that carbon dioxide has a direct effect on temperature because it is the reason for increase in temperature.

The earth's increases in temperature affect climate change because:

This increase in CO₂ traps more heat from the sun in the Earth's atmosphere, causing the planet's temperature to rise. This phenomenon is known as the greenhouse effect. This occurs because CO₂ and other greenhouse gases trap heat in the Earth's atmosphere and prevent it from escaping into space.

There is a significant amount of evidence that supports the relationship between CO₂ and temperature. This includes observational data from ice cores, tree rings, and temperature records, as well as modern-day observations from satellites and ground-based monitoring stations. Computer models also support this relationship and have accurately predicted future temperature trends based on projected CO2 emissions.

Tattooing can be permanent if the ink particles get trapped into the dermis layer of skin.

Since the macrophages cannot degrade the ink, they remain stationary in the dermis and keep the ink contained in their vacuoles, so containing the immune system's onslaught. The tattoo design is thus stuck in the dermis. Tattoo ink is placed in the dermis layer, where it becomes permanent, however it does gradually deteriorate with time. The only way to get rid of a tattoo is to medically remove it or use dermabrasion, laser, or other methods to remove the dermis.

Anaerobic cell respiration results in a low ATP yield from glucose. First, glucose is converted to pyruvate, and NADH and ATP are produced. Pyruvate is then converted to lactic acid in lactic acid fermentation.

Pyruvate is disposed of differently in anaerobic environments. Lactate dehydrogenase, a cytosolic enzyme, converts pyruvate to lactate instead of allowing it to enter mitochondria. This reaction also permits the regeneration of NAD+ from NADH, even though lactate itself isn't used directly as an energy source by the cell. To keep glucose moving through glycolysis, NAD+, an oxidizing cofactor, is required. A direct method of generating energy without the use of oxygen, glycolysis yields two ATP for every glucose molecule. Anaerobic glycolysis is the name for the procedure that breaks down glucose in the absence of oxygen.

Prenatal development, also known as antenatal development, refers to the process that occurs in humans from the time an embryo is formed through the fetus's development to birth (or parturition).

Similar to other animals, the human body is created from a single cell that results from the combination of a male and a female gamete (or sex cell). The prenatal period in humans is divided into three distinct stages that begin with this union: (1) the pre-embryonic stage, which lasts for the first two weeks of development and is characterized by cell division and initial differentiation (cell maturation); (2) the embryonic period, also known as the period of organogenesis, which lasts from the third to the eighth week of development; and (3) the fetal period, which is characterized by the maturation of the placenta.

Flowers on plant help in a berry plant for reproduction.

The flowers of the plant, which are made to draw pollinators, help with plant reproduction. The flower has adapted in a number of ways for this function, including vivid colours, spectacular petals, delicious smells, and even lines on the petals to draw pollinators within.

Inside each flower are the male stamens and female pistils, which are the plant's reproductive organs. The pollen grains (haploid) are formed in the stamen's anther, which is located on top. The anther is kept upright so that it can be pollinated by an insect or the wind by a long filament.

Three components comprise the female pistil. A pollen grain's stigma is its sticky tip. At the base of the pistil, there is an ovary that houses the ovules. The thin stalk that runs from the stigma all the way to the ovary is known as the style.

Sunlight is a key element in photosynthesis that is both easily accessible and not recycled. The photosynthetic mechanism in plants uses light energy from the sun, which is continually available.

Plants absorb water (H2O) and carbon dioxide (CO2) from the soil and atmosphere during photosynthesis. In the plant cell, carbon dioxide is reduced, which means it receives electrons, whereas water is oxidised, which means it loses electrons. Water is converted into oxygen and carbon dioxide into glucose in this process.

Cellular respiration and photosynthesis are significant carbon cycle processes. The processes via which carbon is recycled in the biosphere are known as the carbon cycle.

The equilibrium potential of chloride is -65 mV. Since chloride is a negative ion, it must exit the cell in order for the membrane potential to change from -70 mV to -65 mV by making the cell more positive.

According to G-H-K eqn, the membrane potential will be -67mV. Because of this, chloride ions will be attracted to the outside and repelled from the inside of the membrane.

This will result in a concentration gradient for the ion that is exactly equal to and opposite to the electrical potential across the membrane (-67mV)

Chloride ions always diffuse because the cell does not actively transport the ions; as a result, they do not contribute to the resting membrane potential but instead distribute themselves in accordance with it. Membrane potential can only be measured using the G-H-K equation for K+ and Na+.
