Next week produces a heat wave in Prince George's County. Most scientists would say:
A. Global warming is the cause
B. Human activity is the cause
C. Local temperatures over one week tell us more about weather than climate
D. Our climate is getting warmer
Answer:
A. Global warming is the cause
Explanation:
Our climate is getting warmer due to production of heat wave because the heat wave has high temperature which increases the temperature of the surrounding environment. Researchers found that as global temperatures increase, heat waves will become more frequent and the time between them will become shorter and we know that global temperature increase due to global warming so we can say that global warming is the cause of more heat wave.
GRB2 is the protein that links RTK signaling to integrins and focal adhesions. More precisely, focal adhesions sequester GRB2, removing it from the cytoplasm, and thus preventing it from transducing the signal from the RTK to Ras. Based on this information, say something meaningful about focal adhesions, namely something about the domain structure of one of the proteins within them.
Answer:
It transmit mechanical force and signals.
Explanation:
Focal adhesions are large macromolecular which is responsible for the transmission of mechanical force and regulatory signals between the extracellular matrix and an interacting cell. Focal adhesions act as the mechanical linkages to the ECM, and serves as a biochemical signaling hub to direct numerous signaling proteins at sites of integrin binding and clustering. 68-kD protein also known as paxillin is a type of protein which is part of cytoskeletal component that localizes to the focal adhesions.
A gardener plants 200 flowering plants of the same species. 98 plants have white (v) flowers and the remaining have violet (V) flowers. What must be the allelic frequency of each type of flower? ( p + q = 1, p2 + 2pq + q2 = 1)
A.
violet flowers = 0.55, white flowers = 0.45
B.
violet flowers = 0.62, white flowers = 0.38
C.
violet flowers = 0.3, white flowers = 0.7
D.
violet flowers = 0.49, white flowers = 0.61
The allelic frequency of each type of flower is violet flowers = 0.3, white flowers = 0.7, option C.
What is allelic frequency?The incidence of a gene variant in a population is represented by the allele frequency. The number of times the allele of interest is observed in a population is divided by the total number of copies of all the alleles at that particular genetic locus in the population to calculate the allele frequency and can be expressed as a decimal, a percentage, or a fraction.
To find the allele frequency:
Frequency = 98/200 = p = 0.49 for white (v) flowers
VV - dominant homozygote with violet flowers and with frequency p²
Vv - heterozygote with violet flowers and with frequency 2pq
vv - recessive homozygote with white flowers and with frequency q²
q² = 0.49 = √q² = √0.49 = 0.7
Therefore q in the formula p + q = 1, = p + 0.7 = 1
p = 1 - 0.7 = 0.3
The frequency for violet flowers, p is 0.3 and white flowers, q is 0.7 with substitution method of the "p + q = 1, p2 + 2pq + q2 = 1" formula.

Why are humans able to live in a variety of places on Earth?
Answer:
Early humans used to move from place to place to those days. Reason are given below.
Explanation:
200,000 years ago from the present, modern humans have already started to roam around the planet. They learned everything around them. They risked their lives to become more modern. They invented weapons, tools, hunting, agriculture, communication methodologies and more in order to survive.
During the early ages, humans are the most sensitive species on the planet. They have just evolved to be a six sensed animal and have no idea about the planet. However they have learned to survive on the planet by hunting other animals and eating them. Their life cycle seemed to be stuck with some sort of danger all time. So they wanted to move from place to place in order to survive.
When they started to move across continents, geographical location and climate have influenced their behavior and life style. Humans have started to multiply within some suitable geographical locations. They started to improve their life style by adapting the location.

Suppose we have a disease phenotype that is determined by a single gene with two alleles. Further suppose it follows a autosomal recessive mode of inheritance with reduced penetrance. We have an individual who is unaffected (does not have the disease phenotype) and whose genotype is unknown. We cross this individual with a true-breeding affected individual. How many possible genotypes can this unaffected individual have at the disease locus
Answer:
three (3)
Explanation:
Penetrance can be defined as the proportion of individuals that have mutations associated with a genetic disorder and exhibit symptoms of having that genetic disorder. Moreover, reduced penetrance, also known as incomplete penetrance, indicates that an individual who carries mutations for a disorder but may never develop this disorder. Incomplete penetrance is frequent in some types of cancer, where individuals carry mutations (for example, mutations in the BRCA1 gene which is associated with an increased risk of ovarian cancer), but they may do not develop this condition during their lifetime. Incomplete penetrance may be a result of the interaction between genetic and environmental factors.

DNA sequencing by the chain-termination method utilizes DNA polymerase I to make a complementary copy of the target or template DNA molecule. A reaction with a 20 bp template and dideoxyadenosine nucleotides as terminators results in the production of a 5 bp fragment. Based on this result, we can conclude that the template contains A) a cytosine at position 5. B) a thymine at position 5. C) a cytosine at position 16. D) a thymine at position 16
Answer:
D) a thymine at position 16
Explanation:
The chain termination method (Sanger sequencing), is a sequencing technique used to determine the nucleotide sequence of a specific fragment of DNA. The classical method has three steps: 1- the target DNA fragment to be sequenced is used as a template for chain-termination PCR technique where modified deoxyribonucleotides (ddNTPs) are added to the PCR reactions to be incorporated by the DNA polymerase during in vitro DNA replication, 2-the DNA fragments of different sizes are separated by electrophoresis, and 3-determination of the DNA sequence by observing the identity of the terminal ddNTP in each band of the electrophoresis gel. For example, if the bottom band in the electrophoresis gel colocalizes in the column with ddATP as terminator, then this fragment finishes with ddATP, which means that the last nucleotide from the 5' end is Adenine.

The sex of an organism is typically determined genetically, but environmental factors can also play a role. Scientists examined the roles of genes and environmental temperature in the sex determination of a lizard species. Individuals with a ZWpair of chromosomes are always female (ZWf), while individuals with a ZZ pair of chromosomes can be either male (ZZm) or female (ZZf). Scientists mated ZWf or ZZf females with ZZm males and incubated the eggs produced in 20 clutches at temperatures ranging from 23°C to 36°C. When the young hatched, the scientists determined their sexes (Table 1). Among the eggs that did not hatch, the mortality of embryonic lizards was approximately the same for both males and females.
(b) Using the template, construct an appropriately labeled graph, including error bars, to represent the data in Table 1. Based on the data, compare the ZZm×ZWf crosses and the ZZm×ZZf crosses to determine whether there is a significant difference between the two crosses in the fraction of female progeny produced at 24°C, 32°C, and 36°C.

Clouds are formed when
sunlight causes water droplets to evaporate.
liquid water condenses on grass and windows.
raindrops freeze into tiny pellets and fall to Earth.
water vapor in the air condenses to form liquid water or ice.
Clouds are formed when water vapor in the air condenses to form liquid water or ice. So, the correct option is D.
What are Clouds?Tiny water droplets or ice crystals in the Earth's atmosphere can be seen as visible collections in the form of clouds. They form when moist, warm air rises and cools, causing water vapor in the air to condense into tiny droplets of water or ice. Clouds are formed when water vapor in the air condenses to form liquid water or ice.
As warm, moist air rises and cools, water vapor in the air condenses around fine particles such as dust or salt to form droplets or ice crystals. The ice crystals or droplets then group together to form clouds. The water cycle, which works to move water and energy across Earth's atmosphere and surface, is crucial to the process of cloud formation.
Therefore, the correct option is D.
