Why are archaea in a different domain from bacteria?
A. They are multicellular, but bacteria are unicellular.
B. They are thought to have separate paths of evolutionary
development
C. They are able to perform endosymbiosis, but bacteria are not.
D. They have no similar characteristics.
Answer:B
Explanation:
Archaea is in a different domain from bacteria because they are thought to have separate paths of evolutionary development. Therefore, the correct statement is option B.
What are the differences between archaea and bacteria domains?Archaea and bacteria are both prokaryotic organisms, but archaea are more closely related to eukaryotes than bacteria. Archaea have unique lipid membrane and cell wall components that are different in composition than those found in bacteria.
These differences suggest that archaea and bacteria evolved to have separate paths of evolutionary development early in the history of life on Earth and then classified into Archaea and Bacteria domains.
Based on the phylogenetic tree constructed by researchers, the tree has classified life into three domains which are Archaea, Bacteria, and Eukarya These domains are based on their fundamental genetic and biochemical differences.
Therefore, archaea and bacteria are in a different domain because they followed separate paths of evolutionary development.

Which describes the habitat of a frog?
color for camouflage
prey for snakes
eats insects
marshes and ponds
Marshes and ponds describe the habitat of a frog. So, the correct option is D.
What is Habitat?An area or place where an organism or a collection of organisms naturally lives and thrives is known as a habitat. It includes all the physical, biological and environmental elements necessary for growth and reproduction in a given place. A habitat can be any form of ecosystem, including a forest, desert, ocean, swamp, or dryland.
Temperature, precipitation, soil, vegetation, and other elements that are specific to each ecosystem affect what types of organisms can survive there. Other important elements of a habitat are access to food, water and shelter. Habitat theory is important to ecology and conservation biology.
Therefore, the correct option is D.

Enzymes work fine at any range of temperatures.
A. True
B. False
Answer:
False
Explanation:
Enzymes work best within specific temperature and pH ranges, and sub-optimal conditions can cause an enzyme to lose its ability to bind to a substrate. However, extreme high temperatures can cause an enzyme to lose its shape (denature) and stop working.
What is the relative humidity if the dry-bulb temperature is 26°C and the wet-bulb temperature is 18°C?
Answer:
The amount of moisture air can hold is dependent on its temperature and pressure. The warmer the air the greater the quantity of water vapour it can contain. The air temperature is measured with a normal thermometer this is the Dry-Bulb reading. The actual amount of moisture known as the mixing ratio is measured in grams of water per kilogram of dry air. When air at a certain temperature is saturated it cannot hold any more moisture. The relative humidity of the air is the ratio of the actual amount of moisture in the air to the fully saturated amount.
We can use evaporation to measure the amount of moisture in the air. A wet cloth is placed over the bulb of a thermometer and then air is blown over the cloth causing the water to evaporate. Since evaporation takes up heat, the thermometer will cool to a lower temperature than a thermometer with a dry bulb at the same time and place. The depression in Wet-Bulb temperature allows the humidity to be calculated. If the air is fully saturated (100% relative humidity) the water cannot evaporate, so both the wet and dry bulb temperatures are the same. If the dry and wet bulb temperatures are set to the same value the calculator will show the saturation mixing ratio the amount of water in saturated air at that temperature.
If partly saturated air is cooled without changing its pressure or amount of water vapour, a point is reached when it becomes saturated. The moisture will be given up as dew or ice crystals. This temperature is the Dew Point. This is why condensation will form on a bottle of cold beer, as the air in the vicinity of the bottle is cooled below its dew point. Meteorological reports usually quote the temperature and dew point as well as the station pressure. Moisture content and relative humidity can be calculated from these figures.
The Psychrometer is the name of a device containing both a wet and dry bulb thermometer. This can be a fixed device for meteorology or a handheld sling psychrometer that is often used in air conditioning applications.
Explanation:
The relative humidity if the dry-bulb temperature is 26°C and the wet-bulb temperature is 18°C is 45.1%.
Psychrometer:
It is a device that use to calculate the relative humidity and dew. It has two thermometer, one measures the dry temperature while another measures the wet-temperature.
Given here,
Dry-bulb temperature is 26°C
Wet-bulb temperature is 18°C
The difference between temperature of wet and dry bulb is
= 26 - 18 = 8°C
Now compare the temperature difference to the chart given in the
Therefore, the relative humidity if the dry-bulb temperature is 26°C and the wet-bulb temperature is 18°C is 45.1%.

If the carrot population increased, the rabbit population would:
NO LINK ANSWERS
A. increase
B. decrease
C. remain the same
Answer:
The rabbit population would remain the same as the increase in number of carrots doesn't determine / effect the population of rabbits.
Hope my answer helps !
Answer:
i believe the answer is c) remain the same
Explanation:
i say this because food availability wouldn't necessarily cause the population to grow (there would need to be an environmental change for this to happen.)
and the population wouldn't decrease because there would be an abundance of food and since starvation is one of the main causes of population decrease (along with over-crowding.)

Explanation:
When colorblind women married a male with normal vision, all their daughters have normal vision and all their sons are colorblind. This is an example of which type of inheritance.
Answer:
X-linked recessive
Explanation:
The trait is a sex-linked trait because the daughters are not colorblind, but the sons are. We know this its recessive because the daughters have inherited the mother's X chromosome that has the colourblindness trait, but are not colorblind because the father's X does not have the colourblindness trait. The sons are colourblind because they inherited the X from their mother with the colourblindnese trait and a Y from their father. The colourblindness trait or normal vision trait is not carried on the Y, so the mother's X chromosome's trait is expressed.

The top left, would be light energy from the sun, while the top of the circle would be living beings. Think about it just like plants that that gain energy from the sun through photosynthesis. Then the bottom of the circle would be nonliving beings, either decomposed plants or animals that bring nutrients to soil, or dead ones that we eat. This cycles through until the energy is rereleased through heat. Therefore the top right would be heat energy, every living thing on earth creates gradual amounts of heat. Imagine going for a run, you'll probably be hotter afterwards right? I know it's not the most scientific answer but its 100% right.

Answer:
Tiktaalik roseae
Explanation:
The discovery of the fossil, Tiktaalik roseae on a Canadian island gives credence to the fact that animals moved from living in water to living on dry land. This fish which has feature of land animals such as a neck, skull, and ribs is believed to have lived some 375 million years ago. It also has features of fish such as the fins and scales.

how does the mammalian body protect itself against infections
The body defends against infection by increasing the number of certain types of white blood cells (neutrophils and monocytes), which engulf and destroy invading microorganisms. The increase can occur within several hours, largely because white blood cells are released from the bone marrow, where they are made.
