Answer:
A. 0
B. 1/2 or 50%
Explanation:
Let us assume that the sickle cell anemia trait is represented by s and the alternate normal version by S.
Mary, a carrier would have the genotype Ss.
Mike, a perfectly normal person would have the genotype SS.
If both Mary and Mike marry:
Ss x SS
offspring: SS SS Ss Ss
(A) In order to have sickle cell, the two alleles must be recessive. None of the offspring from the cross has two recessive alleles. Hence, the chances of Mary and Mike having a sickle cell child is zero.
(B) From the cross, two out of four of their potential offspring have the trait in heterozygous condition. Hence, the chances of Mike and Mary having a child who is a carrier is 1/2 or 50%.
What would be a probable explanation for why there are many endemic plants and birds in New Zealand, but no native mammals?
Answer:
Due to isolated before mammals evolve.
Explanation:
There are many endemic plants and birds in New Zealand, but no native mammals because New Zealand is an island which isolated from Gondwana which is a supercontinent about 85 million years ago. Before mammals evolved, the New Zealand splits and go away from the Gondwana. So due to water only those mammals that can swim or fly colonized in New Zealand but not the land living mammals.

What geologic process creates an alcove
A) glaciation
B) wind erosion
C) tectonic uplift
D) coastal erosion
Answer:
wind erosion
- i know this question is older but i hope this helps anyone who may need it. :-)
The geologic process that creates an alcove is wind erosion, which is present in Option B, as the alcove is a recessed area in a rock or cliff face that is often semicircular in shape.
What is wind erosion?Alcove is created by the process of wind erosion. Over time, wind can carry abrasive particles, such as sand or small rocks, that erode the softer rock on the face of a cliff, carving out a hollow space. As the wind continues to erode the rock, the hollow can deepen and expand, forming an alcove. Alcoves are often found in areas with strong, consistent winds, such as desert regions, and can range in size from small niches to large, room-sized spaces. In addition to wind erosion, alcoves can also be created by other geologic processes such as water erosion or tectonic activity.
Hence, the geologic process that creates an alcove is wind erosion, which is present in Option B.

What areas in the United States are currently experiencing air quality disused associated with fire and smoke ?
what is the primary difference between diffusion and osmosis
Long answer here!
In diffusion, particles move from an area of higher concentration to one of lower concentration until equilibrium is reached. In osmosis, a semipermeable membrane is present, so only the solvent molecules are free to move to equalize concentration.
The movement of particles (such molecules or ions) from a region of higher concentration to a region of lower concentration is known as diffusion.
Thus, It happens in a variety of media, including gases, liquids, and solids. The inherent propensity of particles to travel down their concentration gradient in search of equilibrium is the driving force underlying diffusion.
On the other hand, osmosis is a particular kind of diffusion that entails the passage of water molecules over a membrane that is only permeable in certain places. It happens when the solute concentrations on opposite side of the membrane differ.
Thus, The movement of particles (such molecules or ions) from a region of higher concentration to a region of lower concentration is known as diffusion.

Which best describes pitch?
the amount of time taken for a longitudinal wave to produce one cycle the number of cycles per second perceived by the human ear the amplitude of a wave when the natural frequency is matched the distance between two corresponding parts of a transverse wave
The answer is B. the number of cycles per second perceived by the human ear
I got this question right :)
The pitch is the number of cycles per second perceived by the human ear. The correct option is B.
What is pitch?The ability to assess sounds as "higher" and "lower" in the sense associated with musical melodies is known as pitch.
Pitch is a perceptual feature of sounds that allows their ordering on a frequency-related scale.
Pitch in physics refers to a sound wave's specific frequency, which is expressed in Hertz (Hz).
There are two ways in which these frequencies match musical notes. high tone: A high pitch is one that vibrates at a high frequency.
Pitch is a perceptual quantity that depends on the listener, but frequency is a physical quantity that indicates the number of vibrations per second. In truth, our ears perceive pitch rather than frequency.
The pitch is how many cycles per second the human ear can detect.
Thus, the correct option is B.

Prokaryotic cells are single-celled microorganisms known to be earliest on earth.Eukaroyotic cell have a nucleus enclosed within the nuclear membrane and form large and complex organism.
Difference between unicellular and multicellular.
The main difference between unicellular organisms and multicellular organisms is that unicellular organism is unspecialised it means all the body function depends upon only on the single cell and in multicellular organism there is specific cells for specific purposes.
Multicellular and unicellular organisms are perform almost all the life running activities and processes such as respiration, reproduction digestion, breathing, and metabolism.
In unicellular organism division of labour is at the organ level on the other hand in multicellular the division of labour at cellular, tissue, organs and organ system level. Unicellular organism has simple body organization and multicellular organism have complex body organism.
Therefore,the best example that shows the levels of organization in a multicellular organism from the smallest level to the largest is cell, tissue, organ, organ system, organism. Thus, option B is correct.
