This graph illustrates the change in global surface temperature relative to 1951-1980 average temperatures. Nineteen of the hottest years have occurred since 2000, with the exception of 1998, which was helped by a very strong El Niño. The year 2020 tied with 2016 for the hottest year on record since record-keeping began in 1880 (source: NASA/GISS). This research is broadly consistent with similar constructions prepared by the Climatic Research Unit and the National Oceanic and Atmospheric Administration.

The time series below shows the five-year average variation of global surface temperatures. Dark blue indicates areas cooler than average. Dark red indicates areas warmer than average.

The “Global Temperature” figure on the home page dashboard shows global temperature change since 1880. One gets this number by subtracting the first data point in the chart (-0.16°C) from the latest data point (0.85°C).

Sunlight is an unseen factor that affects the carrying capacity of the ocean.

Carrying capacity may be defined as the maximum number of individuals that can be supported by a habitat.

The other options under this question are water chemistry, water availability, space, and sunlight.

Water availability and space both are unlimited in the ocean habitat, while the water chemistry remains the same throughout the ocean.

Therefore, sunlight is an unseen factor that affects the carrying capacity of the ocean.

What happens to the ocean water as it moves from Antarctica to the equator is : ( B ) It becomes less dense and rises to the surface.

The conveyor belt is a system of oceans which transports water and propel deep current of water bodies across the globe based on the differences in water densities.

As the ocean water moves from the Antarctica to the equator the cold ocean water mixes with the warm ocean water at the equator, which makes the water less dense and rises to the surface.

Hence we can conclude that What happens to the ocean water as it moves from Antarctica to the equator is  It becomes less dense and rises to the surface.

Viruses are organisms that share traits with both living and non-living organisms. The virus' genetic material is made up of both DNA and RNA.

A virus is an infectious microorganism made up of a nucleic acid segment (DNA or RNA) encased in a protein coat. A virus cannot multiply on its own; instead, it must infect cells and make copies of itself using the host cell's components. A virus frequently kills the host cell in the process, resulting in harm to the host organism.

Viruses have the following characteristics:

Viruses have an exterior capsule layer and a specified boundary. Only the host cells provide energy to the virus. They thrive and mature, multiplying their numbers solely within the host cells.

Viruses lack the following characteristics:

A virus is a single-celled animal with no more than one cell. In the virus, there is no internal organization. If a virus is present outside of the host environment, it does not grow, develop, or require energy. Viruses do not remove trash.

The average force vehicle experiences is 6000N.  The correct option is B.

It states that the force F is directly proportional to the acceleration a of the body and its mass.

F =ma

Given is a 2000kg vehicle travelling 30m/s takes 10s.

It takes t = 10s to come to rest, then the acceleration will be

a = velocity /time

a = 30/(10)

a = 3 m/s²

According to the Newton's second law of motion.

F = 2000 kg x 3 m/s²

F =6000 N

Thus, the average force vehicle experiences is 6000N.

The two-argument people might make for not preserving botana curus are they take a long time to grow, so it may not be worth the effort; there are organisms that are similar, and it may be expensive.

Botana curus is a precious plant because it yields Carol, a substance that can be used to treat cancer.

Curol cannot be manufactured in a lab. Botana curus grows slowly and is an endangered species, so its ability to produce large amounts of Curol is limited.

Answer:

enzymes don't affect the free energy of the reactants or products

Explanation:

That is, they don't change whether a reaction is energy-releasing or energy-absorbing overall. That's because enzymes don't affect the free energy of the reactants or products. Instead, enzymes lower the energy of the transition state, an unstable state that products must pass through in order to become reactants.

Rhythm Salsa resulted from the development of a muscle cell culture technique.

To obtain a cell culture, it is necessary to disaggregate the original tissue, which can be by mechanical force or enzymatic process. These cells are grown in an adherent layer in a single layer (monolayer) or in organoid format (3D culture) or in suspension.

The exercise reduces the levels of the low-density lipoproteins or the bad cholesterol. It is found that, the people, who exercise daily have a low level of low-density lipoproteins, and an increased level of high-density lipoprotein, which is also known as good cholesterol.

Scientific hypotheses, in general, are the premises within a given theory, which can be validated on the basis of a scientific method, contributing to the formulation of new hypotheses. In this experiment the theory says that cholesterol levels between people who exercise and people who do not exercise is different. Within this theory, the statement says that people who exercise for an hour may have lower cholesterol levels, is a hypothesis that will be confirmed or refuted after the experiment.

The dependent variable is summarized in the phenomena or factors explained or identified, because they are influenced or determined by the independent variable. In this experiment the independent variable is the performance (or not) of exercises. Exercise is what influences or determines cholesterol levels in this study. Thus, cholesterol levels are a dependent variable.

Hence, to check whether a person exercises regularly or not, the scientist can determine the cholesterol level.
