Answer:
For first question the answer will be :
In the taxonomy of Linnaeus there are three kingdoms, divided into classes, and they, in turn, into orders, genera (singular: genus), and species (singular: species), with an additional rank lower than species. a term for rank-based classification of organisms, in general.
And for the second:
The species is the smallest and most exclusive grouping. It consists of organisms that are similar enough to produce fertile offspring together. Closely related species are grouped together in a genus. Linnaean Classification System: Classification of the Human Species.
While for third:
The broadest category in the Linnaean system is the kingdom.Animal Kingdom because Homo sapiens belongs to that kingdom. Other kingdoms include the Plant Kingdom, Fungus Kingdom, and Protist Kingdom.
Hope it helpsWhich statement about compounds is true?
A. A compound has the same properties as the elements from which it is made.
B. A compound has different properties than the elements from which it is made
C. A compound retains the properties of one of its elements, but not the others.
D. Compounds are simpler than elements.
Answer:
B. A compound has different properties than the elements from which it is made
Explanation:
B is true because individual elements have different properties than the compound. Take NaCl (salt) for an example, Na (sodium) by itself is so reactive that if it touches water, it literally blows up (watch videos on the web very neat!), but when we pair it with Cl and make NaCl, it dissolves quietly and neatly, so we see that individuals elements have different properties than the final compound.

You have an egg that has an internal 7% salt concentration and you put it into a bowl of 3% salt water. What is the tonicity of the egg? What is the tonicity of the water in the bowl? Explain what will happen to the egg over time. Assume water can move across the cell membrane but the salt cannot. Be sure to use the appropriate terms to describe what occurs (solvent, solute, tonicity, specific type of transport, etc.) (2-3 sentences) *50 points
Answer:
Egg is HYPERTONIC
Water in the bowl is HYPOTONIC
The egg will become filled with water over time
Explanation:
Tonicity refers to the ability of an extracellular solution to direct the flow of a solvent (water) in and out a cell. There are three types of tonicity; hypertonic, hypotonic and isotonic. A solution is said to be HYPERTONIC when the concentration of solute in it is higher than its external solution. This is the case of the egg cell that contains 7% salt (solute).
A HYPOTONIC solution is that which contains a lower solute concentration than it's external solution. This is the case of the water in the bowl that contains 3% salt concentration.
Tonicity determines which direction osmosis occurs. Osmosis is the movement of solvent/water from a region of high solvent concentration/low solute to a region of low solvent concentration/high solute concentration via a semi-permeable membrane. In this case, water (solvent) will move through the egg cell membrane (semi-permeable membrane) from the bowl with a low solute concentration into the egg with a high solute concentration. Hence, over time, the egg cell will be filled with water.
How does Earth's solid inner core affect seismic waves?
O A. They go faster through the inner core than the liquid outer core.
O B. It blocks S waves from passing through.
O C. They go slower through the inner core than the liquid outer core.
O D. It blocks P waves from passing through.
Earth's solid inner core affect seismic waves as they go slower through the inner core than the liquid outer core.The correct option is C.
The solid inner core affects seismic waves by slowing them down. Seismic waves are waves of energy that travel through the Earth's layers, including the solid inner core and the liquid outer core.
Seismic waves can be either P waves (primary waves) or S waves (secondary waves).P waves are compression waves that can travel through both solid and liquid material. However, S waves are transverse waves that can only travel through solid material.
Thus, option C is correct.

The intertidal zone is home to an abundance of aquatic organisms, like the barnacle, that can survive periods where they are not underwater. What type of tide would most likely decrease the abundance of aquatic organisms, and why?
Downwelling because it creates a cold environment that is not suitable for all aquatic organisms
Upwelling because it creates a cold environment that is not suitable for all aquatic organisms
Neap tide because it creates a small difference between high and low tides, so organisms are in stable environments
Spring tide because it creates a large difference between high and low tides, so the organisms are in extreme environments
Answer:
Spring tide (D)
Explanation:
If it changes the conditions greatly, the organism will suffer and/or perish.
Answer:
Spring tide because it creates a large difference between high and low tides, so the organisms are in extreme environments.
Explanation:
Tide is a concept that expresses the
periodic change of level of the sea, it is believed to be particularly influenced and caused by both the gravitational influence of the sun and the moon on the earth surface.
Intertidal however describes the shore markings of high waters and those of low tide mark.
Spring tide describes the periodic change of sea level that is characterized by the presence of new or full moon, it however is marked with the maximum range of tidal difference caused by the effects of the gravitational influence of the sun and moon in their reinforced form.
The antonym of this tide is the neap tide.
A spring tide is most probably that type of tide that can decrease the abundance of aquatic organisms.
Using the reactants and products of Photosynthesis and Cellular Respiration describe the relationship between the two
Answer:
Refer to bolded below
Explanation:
Photosynthesis involves carbon dioxide and water as the reactants, combining to form glucose and oxygen ( the products ).
Now there is dark photosynthesis and light photosynthesis, where light photosynthesis takes place first considering it converts carbon dioxide (CO2) and water (H2O) into carbohydrates. The ATP energy from the light photosynthesis helps the dark photosynthesis produce the sugars.
______________________________________________________
Cellular Respiration is simply the opposite. Taking the reactants and products into account, you could simply switch the two and the reactants of photosynthesis = products of cellular respiration, and vice versa. However, ATP energy is made in both. In fact Photosynthesis actually uses some ATP energy in it's chemical reaction...
Thus, we can conclude that Photosynthesis is quite the opposite of Cellular Respiration ( in terms of their chemical formula )

How Human sex gets decided?
Human sex gets decided by the function of SRY gene which possessed by with or without of Y chromosome. The hormone of anti-mullerian and testosterone produced from cells when activating the SRY gene. It generally confirms the development of single-male reproductive systems.
The scenario in humans, the sex ration gets affected by the male parent's hormone level. Also, in XY sex evaluation system, the sperm of male takes part in X or Y chromosome whereas the ovum from female contributes to X chromosome. This greatly results in offspring - either male (XX) or female (XY).
She creates the Punnett square cross below to show sex inheritance. She come to know that both parent determines the sex of a baby and it is when you put xx and xy on a punnet square there are equal amounts male and female.

In coastal areas, wind moves sand, blowing away or engulfing the soil, and eventually creating sand dunes is the type of Primary succession. So, the correct options for 1, 2, 3 and 4 are Primary succession, Secondary succession, Secondary succession and Primary succession respectively.
What is Primary and Secondary succession?When a new piece of land is produced or is first exposed, primary succession occurs. This may occur, for instance, when lava solidifies and forms new rocks or a glacier recedes and reveals bare rocks. In the initial succession, organisms have to start over.
When a place is disturbed but not severely enough to completely clear it of all vegetation and soil, secondary succession happens. Secondary succession can be started by a variety of disturbances, including wildfire, flooding, windstorms, or human activity (such as logging of forests).
Example of these successions are:
1.) In coastal areas, wind moves sand, blowing away or engulfing the soil, and eventually creating sand dunes: Primary succession
2.) The introduction of livestock to an area leads to over-grazing that removes native grasses: Secondary succession
3.) A forest is cleared to gather lumber used for building houses: Secondary succession
4.) A lava flow down the side of a volcano destroys all vegetation and eventually turns into volcanic rock when it cools and hardens: Primary succession

Answer:
The mouse and shrew bones were common to all three owls so they were not useful in identifying environments. The gopher bones were unique to the great grey owl of Alaska. Gophers are rodents that are successful in areas with soft soil and lots of grass, so the gopher and this owl would be found in the meadows and evergreen forests of Alaska. The bat was unique to the barking owl of Australia. The bat would be found in woodland habitats where there are many trees the bat can hang from. The gull bones were unique to the short-eared owl of Cuba. Gulls are wetland birds, so the gull and this owl would be found in marshes and coastal areas.

Scientists can track the movement of proteins through the endomembrane system using an approach known as a pulse-chase experiment. This experiment involves • the “pulse” phase: Cells are exposed to a high concentration of a radioactively labeled amino acids for a short period to “tag” proteins that are being synthesized. • the “chase” phase: Any unincorporated (not used to make proteins) radioactively labeled amino acids are washed away and large amounts of the same, but unlabeled, amino acid are added. Only those proteins synthesized during the brief pulse phase are radioactively tagged. These tagged proteins can be tracked through the chase period to determine their location in the cell. The data below were obtained from a pulse-chase experiment in which cells were examined at different times during the chase period. The numbers represent the radioactivity (measured in counts per minute) recorded at each of the indicated sites. The higher the number, the greater the radioactivity. Table 1.

Think of the shape of a wave. It looks like a squiggly line. We know the highest part of that line is the peak. The wavelength is the distance between wave peaks. Waves of the same type can differ in wavelength. For example, the wavelength of light waves determines its color. Amplitude is the measurement of a wave's height. It is measured in two ways. Peak-to-peak amplitude is the distance between the peak (the topmost part of a wave) and the trough (the lowermost part). Semi-amplitude is half the peak-to-peak amplitude. Most of the time when people refer to "amplitude," they are referring to the semi-amplitude: the distance from the middle of the wave to the top, or the middle of the wave to the bottom. The amplitude of a sound wave determines its volume.
Which of the following best explains the relationship between peak-to-peak amplitude and semi-amplitude?
A Semi-amplitude is half the distance of the peak-to-peak amplitude.
B Semi-amplitude is the same distance as the peak-to-peak amplitude.
C Semi-amplitude is double the distance of the peak-to-peak amplitude.
