How did endosymbiosis impact the structural differences between bacteria, animals, plants and fungi?
Answer:DNA, RNA, Ribosomes and Protein Synthesis
This provided the first substantial evidence for the endosymbiosis hypothesis. It was also determined that mitochondria and chloroplasts divide independently of the cell they live in.
Explanation:
What role did endosymbiosis play in the evolution of eukaryotes? Endosymbiosis led to the evolution of eukaryotic cells with mitochondria and chloroplasts. This kind of natural selection led to the evolution of eukaryotic cells and the plants and animals we see today.

If viruses are not living, how do they cause disease?
Answer:
In an episode of the classic 1950s television comedy The Honeymooners, Brooklyn bus driver Ralph Kramden loudly explains to his wife, Alice, “You know that I know how easy you get the virus.” Half a century ago even regular folks like the Kramdens had some knowledge of viruses—as microscopic bringers of disease. Yet it is almost certain that they did not know exactly what a virus was. They were, and are, not alone.

How does an organisms life begin?
Answer:
Living organisms undergo growth and development. Every living organism begins life as a single cell.
Answer:
The life of an animal organism, obviously, begins at conception. But human life begins only at the moment that the animal has a mind. In some, very fast, developers this can happen before the age of one year; in a large majority of cases this happens between two and three years of age.
Explanation:
A mineral forms from water at the edge of a lake. Which statement best describes this mineral? The mineral formed from lava. The mineral formed through evaporation. The mineral formed when hot water cooled. The mineral crystallized from magma.
Answer:
The mineral formed through evaporation.
Explanation:
Minerals are inorganic substances that occur naturally i.e. not man-made. These minerals are formed in different ways in nature. One of those ways is through EVAPORATION.
Since water dissolves a lot of substances including the particles of these minerals, the mineral components can be found in a dissolved state in water bodies e.g lakes, oceans etc. However, when heat increases and the water molecules evaporate (change to gas), the dissolved minerals in these water bodies crystallize out.
This is what happens when minerals form at the edge of a lake. The water from the lake evaporates leading to the formation of minerals.
Answer:
The mineral formed through evaporation.

Meat tenderizer contains an enzyme that interacts with meat. If meat is coated with tenderizer and then placed in a refrigerator for a short time, how would the enzyme be affected?
Answer:
The enzyme would be deactivated.
Explanation:
Enzymes are usually deactivated by low temperatures.
Enzymes are proteinous in nature, function by catalyzing biological reactions, and have a particular range of temperatures where they function optimally. Above these temperatures, the catalyzing attribute of enzymes gradually declines till they are denatured by high temperature and below the optimal temperature, their catalyzing attributes also decline. However, instead of being denatured by very low temperatures, they become deactivated instead.

Explanation:
Quantitative data measures categories like color or movie genre.
True
False
Answer:
[tex]\boxed {\tt False}[/tex]
Explanation:
First, let's define quantitative data.
Quantitative data is
Data that can be expressed as a number or a quantity. This type of data can be measured, for example: length, temperature, time, etc.There is also another kind of data, called qualitative data.
Qualitative data is
Data that is expressed with descriptions. This type of data is observed. Examples include: colors, smells, tastes, etc.We are asked about color and movie genre. This can't be measured or expressed as a number, so it is not quantitative data. Instead, it is qualitative data.

A tide table shows the date, time, and height of the predicted tides. What type of tide is the following table representing, semidiurnal, mixed semidiurnal, or diurnal? Date Day Time Height 11/30 Mon 11:58 am 6.34 H 11/30 Mon 11:43 pm 2.16 L 12/1 Tues 11:01 am 6.27 H 12/1 Tues 11:30 pm 1.99 L
Answer:
the date
Explanation:
A tide table shows the date, time, and height of the predicted tides. The type of tide that the given table represents is mixed semidiurnal.
What is a mixed semidiurnal tide?A mixed semidiurnal tide is a tide that has two high tides and two low tides of different magnitudes in each day. The interval between consecutive high tides or low tides is almost the same.
The height of the tides changes every day due to the gravitational pull of the Sun and the Moon on the Earth's ocean water. The influence of the Moon on tidal patterns is more significant than that of the Sun.
Therefore, a mixed semidiurnal tide is the one with two high and two low tides of different magnitudes in each day, which is represented by the given tide table. All of these characteristics indicate a semidiurnal tide pattern.
