Answer:

30% thymine

Explanation:

If 30% of Adenine is present, it would be reasonable to assume that 30% of Thymine will be present, as the ratio between the two complementary nitrogenous bases will be roughly equal. Therefore, that leaves us with 40% between Cytosine and Guanine.

Answer:

Ecosystem services play important role in human sustainability. Ecosystem services include provisioning,regulating, supporting, and cultural.

Provisioning include production of food and water which is one of the essential requirement for human survival and provided by ecosystem in the form of plants or other animals. No food means no human life.

Regulating may include the control of disease and climate.Humans at different regions are susceptible to particular temperature and diversity in Climate provide required atmospheric condition for human survival. Climatic changes causes global warming which bring many diseases and temperature fluctuations that affect human sustainability. Diseases decreases human population and affect human susceptibility so ecosystem controls the diseases that increases chance of human survival. More diseases with no medicine may result into high mortality rate.

Supporting, such as oxygen production and nutrient cycles are important factors that support human sustainability because nutrients provide energy to humans to do work and oxygen is must for their living.

Cultural involve recreational and spiritual benefits. Recreational and spiritual benefits include regulation of physical and mental health and social interaction with  other people  that keeps a human healthy and happy for living a good life.

Hence, ecosystem services promote and affect human sustainability.

Answer:

Archaea bacteria

Explanation:

just search each answer choice asking if its eukaryotic or prokaryotic and it will tell you

Bacteria and Archaea are groups of organisms that are prokaryotic, which means that their cells do not have cellular organelles or a delimited nucleus in the cytoplasm.

The prokaryotic cell is characterized by not having a cell nucleus, therefore its ribosomes are smaller and its genetic material simpler.

Prokaryotes are, in most cases, unicellular microorganisms.

The bacteria is a unicellular and prokaryotic microorganism, which means that it does not have a nucleus, they are a few micrometers long and various shapes including spheres (cocci), rods (bacilli) and helices (spirils).

A diversity of unicellular microorganisms that make up the archaea kingdom lacking nuclei (prokaryotes) is known as archaea.

Their cells are surrounded by a covering (cell wall) made of various materials that give them high resistance against antibiotics or other harmful substances.

Therefore, we can conclude that bacteria and archaea are groups of organisms that are prokaryotic, which do not have a defined nucleus and or organelles surrounded by a membrane.

Explanation:

Answer: 4)Biomes

Explanation:

Groups of ecosystems that have the same climate and dominant species

are known as biomes, e.g. tundra or rainforest biomes.

Answer:

The correct answers are "heterozygous", and "homozygous dominant".

Explanation:

Galactosemia is a condition where people are not able to process the sugar galactose. People with this condition have one gene mutated, which does not allow the proper synthesis of the enzyme that breaks down galactose. Galactosemia is inherited as an autosomal recessive genetic condition, therefore, only children that are homozygous recessive develop the condition. Children that are heterozygous or homozygous dominant, will not develop galactosemia.

Answer:

its heterozygous and homozygous dominant

Answer:

Explanation:

The graph that shows the presence of nitrogen fixing bacteria in the soil would be graph 2.

Nitrogen fixing bacteria are bacteria that are capable of converting atmospheric nitrogen into plant-usable nitrogen in the soil. The conversion is done in two stages;

1. First, atmospheric nitrogen is converted into ammonia.

2. Ammonium is converted into usable nitrate

Hence, the correct graph is the one in which the amount of atmospheric nitrogen decreases with a corresponding increase in the amount of ammonia. This would indicate the conversion of nitrogen into ammonia which is the first step in nitrogen fixation by nitrogen-fixing bacteria.

Graph 2 represents the presence of nitrogen-fixing bacteria in the soil.

This is because in this graph the concentration of atmospheric nitrogen (N2) is lower and the concentration of ammonium (NH4) is higher. The nitrogen-fixing bacteria converts or fixes atmospheric nitrogen that can't be absorbed by the plants into ammonium or nitrates which can be absorbed by the plants and make necessary amino acids for the body so we can conclude that graph 2 indicates the presence of nitrogen-fixing bacteria in the soil.

Answer:

To examine the importance of light to a plant's growth.

Explanation:

To give a background to this question, I will define a key term "Photosynthesis". Photosynthesis is a compound word made up of photo (which means "light") and synthesis (which means "to put together").

It is the process by green plants use sunlight to obtain nutrients from carbon dioxide and water.

The experiment us meant to examine the effect of deprivation of sunlight on a plant's growth.

Therefore, the essence of keeping one set of seedlings in the light is to compare if there is any difference in growth between the seeding kept in the dark cupboard and that kept in the light.

This enables us to conclude whether or not light is important for the growth of a plant.

Answer:

B. Voltage is when current flows from higher to lower potential energy.

Explanation:

Voltage refers to the difference in electric potential between two points. Current in the wire always flow from higher potential to lower potential due to voltage. At the electric source, voltage of current is high but when it moves through wire, the amount of current decreases when it reaches to the other end of the circuit. This is because of the resistance present inside the wire which causes heat energy and some of the current is lost.

The correct answer is option B. Voltage is when current flows from higher to lower potential energy.

Voltage is the difference in charge, in this case, made by the electrons, that results in electrons flowing from a place of high concentration to one of low concentration. We call the flow of electrons current, and we measure voltage in Volts (V).

It is a unit that we use to measure the intensity of the current.
