Explanation:
Consider the following alleles: X1, X2, X3. The different alleles encode enzymes with slightly different ratesof reaction, but are otherwise identical. Consider a population that is sampled for these alleles at two different times. Below are the genotypes for each individual in this population at time 1. For the Time 1 population calculate the allele frequencies and genotype frequencies.(4points)

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.

Research the effect of insulin on blood sugar after a meal. You may use outside sources. Select the correct statement. Insulin has no effect on blood sugar. Insulin increases blood sugar. Insulin reduces blood sugar.
Answer:
Insulin reduces blood sugar.
Explanation:
Insulin is an hormone produced naturally in the pancreas organ of the body. Insulin is majorly involved in digestion where it helps in the absorption process. Insulin aids the absorption of glucose by cells.
When a meal is eaten, the food digests and breaks down into GLUCOSE, which enters into the blood stream via the small intestine. Insulin ensures that the sugar (glucose) content in the blood REDUCES by moving glucose into cells for respiration (energy production) and storing the excess glucose as glycogen in the liver cells.

A controlled experiment was conducted to analyze the effects of darkness and boiling on the photosynthetic rate of incubated chloroplast suspensions. The dye reduction technique was used. Each chloroplast suspension was mixed with DPIP, an electron acceptor that changes from blue to clear when it is reduced. Each sample was placed individually in a spectrophotometer and the percent transmittance was recorded. The three samples used were prepared as follows.
Sample 1 – chloroplast suspension + DPIP
Sample 2 – chloroplast suspension surrounded by foil wrap to provide a dark environment + DPIP
Sample 3 – chloroplast suspension that has been boiled + DPIP
On the axes provided, construct and label a graph showing the results for the three samples.

A student is sitting in class drinking a 16.9 fl oz bottle of Arizona tea (the size that you get from the deli). The student isn’t doing any activity, so the student’s body doesn’t need the sugar right away. What happens to all the sugar?
Answer:
The sugar is stored as glycogen in the students body
Explanation:
The food we consume contains sugar molecules (carbohydrate) that is broken down via respiration to synthesize energy (ATP). However, the sugar is not always utilized at once as the excess is stored as a carbohydrate called GLYCOGEN in our liver cells or muscle.
According to this question, a student is sitting in class drinking a 16.9 fl oz bottle of Arizona tea. The student, however, is not doing any activity and so his/her body does not need the sugar right away. This means that the body will store the sugar as GLYCOGEN until it is needed.
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

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.
