Answer:
Breeze. The formation of sea and land breeze form the classic examples of convection. Going by the definition of convection, the molecules at a higher temperature displace the ones at a lower temperature. Similarly, in the afternoon, the surface of the land near the sea is warmer as compared to in the evening.

In humans, brown eyes (B) is dominant over blue eyes (b). Teddy has brown eyes, his mother has brown eyes and his father has blue eyes. Their punnett square is represented in the picture attached:
Teddy says that all 4 children in his family have brown eyes. Is this possible?
Question 12 options:
a. Yes, because every child has a 50% chance of having brown eyes
b. No, they should be half brown eyes and half blue eyes
c. No, at least one of his siblings should have brown eyes
Answer:
A. Yes, because every child has a 50% chance of having brown eyes
Explanation:
This is the correct answer
According to the Punnett square that is given below, the argument made by Teddy may not have correct evidence. This is because it is not possible to have all 4 children in his family has brown eyes. So, the correct option for this question is B.
What is Punnett square?A Punnett square may be characterized as a type of table in which all of the plausible consequences for a genetic cross between two individuals with known genotypes are given.
According to the context of this question, the genotype of the mother is Bb which has a brown phenotype because brown eye (B) is dominant over blue eyes (b). While the genotype of the father is bb. This is blue eyes.
When both these genotypes are crossed, the genotypes of offspring are Bb, Bb, bb, and bb. This means that the individuals have both traits of blue and brown phenotypes by 50% each.
Therefore, the correct option for this question is B.

Phillip Gingrich finds an S-shaped bone in this partial skull, a sigmoid process, which is unique to
one particular order of animals in the water today... which one?
Answer:
A primitive whale which he named Pakicetus.
Explanation:
Philip Gingrich is a vertebrate paleontologist at the University of Michigan. He has performed extensive research on whales at the Egyptian desert of Wadi Hitan. His research team member discovered a skull whose braincase was bigger than that of a walnut. Gingerich was able to link the small-brained animal, to an early whale.
The auditory bulla had an s-shaped bony crest known as the sigmoid process and these two features helped whales to hear in water. The case, however lacked other features that helped whales hear beneath the waves. This led Gingrich to the conclusion that the unknown animal was semi-aquatic. This finding also lent credence to the possibility of whales evolving from terrestrial animals.

Which property of DNA contributes the most to DNA's ability to
replicate?
A. DNA coils into a long spiral or helix
B. DNA has two complementary strands that can separate
C. Each strand of DNA has a sugar-phosphate backbone
D. Each strand of DNA can be made of a unique sequence of
four different bases
The property of DNA contributes the most to DNA's ability to replicate is DNA has two complementary strands that can separate. Thus, option B is correct.
In how many steps replication occurs?Replication has been occurs in three major steps is the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin.
DNA replication has been known the biological process of producing two identical replicas of DNA from one original DNA molecule.DNA replication occurs in all living organisms acting as the most essential part of biological inheritance.
This is essential for cell division during the growth and repair of damaged tissues, while it also ensures that each of the new cells receives its own copy of the DNA. The cell possesses the distinctive property of division, which makes replication of DNA essential.
Therefore, The property of DNA contributes the most to DNA's ability to replicate is DNA has two complementary strands that can separate. Thus, option B is correct.

Rr x Rr what percent of the offspring will be round
Answer:
75%
Explanation:
The allele for the dominant round phenotype is represented by R while the allele for recessive wrinkled phenotype is represented by r. In this question, two heterozygous parents are crossed i.e. Rr × Rr.
These parents will produce gametes as follows: R and r. Using these gametes in a punnet square (see attached image), the following offsprings will be produced: RR, Rr, Rr and rr. The RR, Rr, Rr offsprings will have a round phenotype while the rr will have a wrinkled phenotype. This means that 3/4 × 100 = 75% of the offsprings will be round.
A confounding variable is an outside variable beyond the control of the race teams and official. What are some confounding variables that could contribute to the speed of the tracks?
Answer:
rain and turns
Explanation:
There are various confounding variables that could contribute to the speed of the track, one of which is rain. Rain is something that the race teams and officials cannot control and affects the speed at which racecars can operate on a track. This is because the Rain wets the tracks which prevents the cars wheels from properly gripping the track and instead causes them to skid. Another confounding variable would be turns. A track that has more turns would drastically decrease the speed of the tracks as cars would need to slow down for each turn.

List 4 concepts you learned in this unit about waves and explain how each one applies to your life (4 points)
Answer:
amplitude, wavelength, frequency, and speed.
Explanation: Sound is a type of wave that moves through matter and then vibrates our eardrums so we can hear. Light is a special kind of wave that is made up of photons. You can drop a rock into a pond and see waves form in the water. We even use waves (microwaves) to cook our food really fast. Water waves are the focus of our Tsunamis and surf resources, but many other kinds of wave exist. These include sound waves, light waves, radio waves, microwaves and others. All kinds of waves have the same fundamental properties of reflection, refraction, diffraction and interference, and all waves have a wavelength, frequency, speed and amplitude.
2. Order the steps of mineral formation from the first stage to the final stage.
Answer:
(1) igneous, or magmatic, in which minerals crystallize from a melt, (2) sedimentary, in which minerals are the result of sedimentation, a process whose raw materials are particles from other rocks that have undergone weathering or erosion, (3) metamorphic, in which new minerals form at the expense of earlier ones owing to the effects of changing—usually increasing—temperature or pressure or both on some existing rock type, and (4) hydrothermal, in which minerals are chemically precipitated from hot solutions within Earth.

How long will it take for 40.0 grams of Radium-226 (Ra-226) to decay to leave a total of 2.5 grams of Ra-226? Ra-226 has a half-life of 1600 years.
Answer:
6400 years
Explanation:
Given that;
N/No =(1/2)^t/t1/2
No = amount of radioactive material originally present
N = amount of radioactive material present at time t
t= time taken for N amount of radioactive material to remain
t1/2 = have life of the radioactive material
2.5/40 = (1/2)^t/1600
1/16 = (1/2)^t/1600
(1/2)^4 = (1/2)^t/1600
4 = t/1600
t = 4 * 1600
t = 6400 years
