Answer: make

Explanation:

Answer:

23%

Explanation:

According to Chargaff's law A = T and G = C

T = 27%

A = 27%

27 + 27 = 54

100 - 54 = 46

46/2= 23

So 23%

Answer:

Offspring will have some sort of genetic variation from parent (may be positive or negative or no effect,  based on the mutation type)

Explanation:

The reproductive cells pass on the traits from the parents to the offspring.

An organism that is mutated at a single DNA location in a reproductive cell, then that mutation will be passed on to the offspring.

Based on fact, that mutation will lead to some kind of effect in any trait, hence the same trait will be effected because of mutation in the offspring as well

It can also be said that offspring will have some sort of variation from parent (may be positive or negative or no effect,  based on the mutation type)

Answer:

Decomposers

Explanation:

Without decomposition, there is no life really. Although producers give off oxygen and food to consumers, they need organic and inorganic materials, water, air, carbon dioxide, etc. While decomposers, work with what they got

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.

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.

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.

Answer:

A community is all the populations in an area. The terms Population and Community are used in ecology to describe a group of different species inhabiting the same geographical space at a particular time. These diverse organisms stay together because of the need of food.

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%.

Explanation:

Biodegradable products do not really present any problems because they can decompose on their own, thus they do not create any pollution. Aluminum is not as dangerous to the environment as plastics, for example.

Answer:

two chromatids

After DNA replication, each chromosome now consists of two physically attached sister chromatids. After chromosome condensation, the chromosomes condense to form compact structures (still made up of two chromatids). As a cell prepares to divide, it must make a copy of each of its chromosomes.

Answer:

Atmosphere

Explanation:

carbon dioxide is naturally released into the atmosphere by the decay and flatulance of animals. But you extract fossil fuels from the ground and burn them. The burning of fossil fuels is called combustion.

Marshes and ponds describe the habitat of a frog. So, the correct option is D.

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.

Answer:

The other two subphyla are invertebrate chordates that lack a backbone. Members of the subphylum Urochordata are tunicates (also called sea squirts). Members of the subphylum Cephalochordata are lancelets. Both tunicates and lancelets are small and primitive.

Explanation:

Not really an explanation for this one.

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.
