Answer:
1. low angle, and upper atmospheric air is sinking
Explanation:
Weather can be defined as the atmospheric conditions of a particular area over a short period of time. Some of the elements of weather are wind, humidity, temperature, air pressure, precipitation and clouds.
Basically, the weather of a particular area or region may change hourly, daily, monthly or even annually.
On the other hand, climate refers to the change in the atmospheric conditions and manifestation of weather in a particular area over a long period of time usually 30 years.
In Science, Earth's polar regions refer to the areas that are typically located between the North Pole and the Artic Circles or South Pole and the Antarctic Circles.
The very cold temperatures found in polar regions causes the air to be very dry and as such there's no much atmospheric moisture; reducing the amount of precipitation (rain, sleet, snow or clouds) drastically.
At higher altitudes (heights above sea level), the angle of incidence of the sun's ray (sunlight) is usually at a low angle striking the tilted surface of the Earth.
Hence, Earth's polar regions have cold, dry climates because the Sun's rays are at a low angle, and upper atmospheric air is sinking, which leads to an increase in the amount of heat received.
Earth's polar regions have cold, dry climates because the Sun's rays are at a low angle, and upper atmospheric air is sinking.
Climate of a Polar RegionThe two most important factors in the climate of an area are temperature and precipitation. The temperature of Polar areas are in negative because the sun's rays strike these areas at very low angles.
Due to very cold temeperature there is no moisture in the air, and hence the air is very dry, this is why the Precipitation in Polar areas is too low. Hence, the polar region have cold, dry climates. Therefore, as per above statment we can say that the correct option is 1. Low angle, and upper atmospheric air is sinking.

why the solute can't move from higher concentration to lower concentration?
Answer:
yes, so when the concentration of a solute is high, the concentration of water is lowered since there is more solute per water, less water per solute. Thus, when water moves from low concentrations of solute to high concentrations of solute, it moves from high concentrations of water to low concentrations of water.

Which of the following is NOT a rapid (fast) change in Earth's surface? *
1 point
landslides
volcanoes
deltas
earthquakes
HELPPPPP PLZ NEED IT BY TODAY PLLZZZZZZ 10 PIONTS
Answer:
delta
Explanation:
deltas take time to cause changes in the earth's surface as it takes time for water to erode and change things. volcanoes takes minutes to burn and ruin anything in its path, and landslides destroys everything in its path as well immediately.
A rapid or fast change can be defined as one that occurs quickly within a short amount of time.
Among the given example of changes, the types of changes are as follows:
Landslides - It is a result of imperceptive downslope movement and can occur within 10 seconds.Volcanoes - The eruption of volcanoes takes only a few seconds.deltas - The slow and steady flow of rivers form deltas and may take up to thousands of years.Earthquakes - It occurs within a few seconds after the fault ruptures and the ground shakes.Thus, the change that is not rapid is the formation of deltas.

1. Which of the following most accurately complete the statement below -
An increase in biodiversity result in
A. More competition for abiotic factors
B. Less competition for biotic factors
C. An increase in the sustainability of an ecosystem
D. A decrease in the sustainability of an ecosystem
Answer:
The correct answer is - C. An increase in the sustainability of an ecosystem.
Explanation:
Biodiversity is the variety of different biological species and populations on the earth or in an ecosystem. Biodiversity helps in maintaining health by providing food and other resources. Higher biodiversity healthier the earth.
Sustainability is the ability to maintain the ecological process and its structure and function in case of external stress for a longer time. The more sustainability of an ecosystem the healthier the ecosystem. The biodiversity of an ecosystem provides sustainability to the ecosystem. An increase in biodiversity will lead to a more sustainable ecosystem.

write the compliment triplets for the DNA sequence in each box in the following “ATG, ATC, GCA, AGT, AGC, GCC, GAT, AAG, TTG, CAG, TAG
Answer:
The complementary DNA sequence of each triplet is as follows:
ATG - TAC
ATC - TAG
GCA - CGT
AGT - TCA
AGC - TCG
GCC - CGG
GAT - CTA
AAG - TTC
TTG - AAC
CAG - GTC
TAG - ATC
Explanation:
A double-stranded DNA molecule is made up of two strands of DNA whose sequence are complementary to one another and linked by hydrogen bonds. According to the complementary base pairing rule as postulated by Chargaff, Adenine base will always hydrogen pair with Thymine base while Guanine base will always hydrogen pair with Cytosine base i.e. A-T, G-C
Based on the above explanation, the following triplets of DNA will have the following complementary sequences:
ATG - TAC
ATC - TAG
GCA - CGT
AGT - TCA
AGC - TCG
GCC - CGG
GAT - CTA
AAG - TTC
TTG - AAC
CAG - GTC
TAG - ATC

Human blood type is determined by three alleles IA, IB, and IO. The alleles IA and IB are co-dominant to each other, and both are dominant to IO. Within a large, randomly mating population (540,000 individuals), the frequencies for the blood type alleles are 0.3 for the IA allele, 0.6 for the IO allele, and 0.1 for the IB allele. Calculate the expected numbers of people in the population having the blood type of A.
Answer:
1a. Number of people in the population with blood group A = 243000
1b. Number of people in the population with blood group B = 70,200
1c. Number of people in the population with blood group AB = 32,400
1d. Number of people in the population with blood group O = 194000
2. The percentage of type B people that are heterozygotes (IBIO) = 12%
Note: The question is incomplete. The complete question is given below:
Human blood type is determined by three alleles IA, IB, and IO. The alleles IA and IB are co-dominant to each other, and both ar e dominant to IO. Within a large, randomly mating population (540,000 individuals), the frequencies for the blood type alleles are 0.3 for the IA allele, 0.6 for IO, and 0.1 for the IB allele. a. Calculate the expected numbers of people in the population having each blood type A, B, AB, and O. b. 2. Determine the percentage of type B people that are heterozygotes (IBIO).
Explanation:
According to Hardy-Weinberg equilibrium equation, p²+q²+2pq=1
Where heterozygote allele 2pq,
p² = dominant h0m0zygous frequency
2pq = heterozygous frequency
q² = recessive h0m0zygous frequency
1a. Blood group A has two genotypes- IAIA and IAIO
The genotype frequency will be:
IAIA= 0.3 X 0.3 = 0.09
IAIO= 2 × 0.3 x 0.6 = 0.36
Total genotype frequency = 0.09 + 0.36 = 0.45
Number of people in the population with blood group A = 0.45 × 540,000 = 243000
b. Blood group has two genotypes- IAIB and IBIO
The genotype frequency will be:
IBIB= 0.1 x 0.1 = 0.01
IBIO = 2 × 0.1 x 0.6 = 0.12
Total genotype frequncy = 0.13
Number of people in the population with blood group B = 0.13 × 540,000 = 70,200
c. Blood group AB genotype frequency is 2 × IAIB x IAIB
Blood group AB = 2 × 0.3 x 0.1 = 0.06
Number of people in the population with blood group AB = 0.06 × 540,000 = 32,400
d. Blood group O has one genotype IOIO
IOIO = 0.6 × 0.6 = 0.36
Number of people in the population with blood group O = 0.36 × 540000 = 194000
2. Genotype frequency of heterozygote IBIO blood group = 2 × IB × IO
2 × 0.1 x 0.6 = 0.12 = 12%
The percentage of type B people that are heterozygotes (IBIO) = 12%

Normal red blood cells slide easily through narrow blood vessels. In sickle cell disease, many red blood cells change to a crescent shape like a slender moon. Crescent-shaped blood cells cause blockages in blood vessels. These blockages decrease the transport of oxygen. People with sickle cell disease often have sharp pains due to the lack of oxygen in parts of the body.
