Specialized proteins called cell cycle regulators, such as p53 and p21, regulate the progression of the cell cycle from one phase to the next. This progression through the checkpoints is strictly regulated and usually works without error. When errors do occur, they can have catastrophic consequences, including cancer. How did this study lend new evidence to our understanding of how genes regulate the cell cycle, giving us a better chance of developing successful cancer treatments

Answers

Answer 1

Answer:

The change in the genes p53 and p21 results in deficits in checkpoints that result in cancer of various types. The G2-HM checkpoint deficits can be exploited in the development of targeted treatment.

A mutation in the above normal functioning of p53 can lead to the progression of damaged cells to mitosis which leads to cancer. So therapeutics which target any of these checkpoints can lead to developing a treatment for cancer.

why are the models of solar systems that you can purchase in stores not to scale?

Answers

Answer:

It's impossible to find a solar system model that is to scale because of how large the solar system is. The solar system is about 287 billion km, making it impossible to purchase or even create a solar system model that is to scale.

The models of the solar systems purchased in stores are not to scale because they are too large to be replicated to scale.

The solar system is a series of planetary bodies which consists of the sun and planetary bodies which orbits around the sun. The solar system is immensely huge with an approximate diameter of about 287.46 billion kilometers.

The entire earth itself has an approximate Circumference of about 40,075 km which is extremely small in comparison to the solar system's diameter.

This means that to produce a model of the solar system to scale, the diameter of the replicated model will be 287.46 billion kilometer which is impossible as it is too large to be replicated to scale even immensely larger Than the diameter of the earth.

The middle course - where the river starts the slow down. it gets wider. and travels in winding loops. there is a lot of lateral erosion, deposition and transportation. the middle course can take up most of the river

The lower course - the last course if a river . the gradient is at its gentlest, as the river approaches the sea. rivers usually have a wide, smooth channel, and water moves it slowest.

The ability to grow differently colored fur based on the season provides Arctic foxes with a selective advantage. What do you think that is

Answers

Answer:

This is known as Phenotypic plasticity, the artic fox has the advantage of being able able to hunt rodents, birds and fish

Explanation:

Phenotypic plasticity can be explained as the changes in the behavior, morphology, physiology of an organism such as the artic fox in response to their unique habitat. It tells us how the artic fox is able to cope with the variations in it's environment.

Their natural hues helps them to blend into snow and ice since it is white. When there's a change in season, their fur or coat also changes as well to a brown or grey color that gives it cover when it is among rocks and plants.

These colorings gives them an advantage and help them to hunt rodents, birds and fishes.

This is known as phenotypic plasticity, but artificial foxes have the advantage of explaining rodents, birds, and fish fox reactive to their unique habitats.

It will tell you how artistic foxes can handle environmental fluctuations. Her natural shades help you mix himself with snow and ice like white. If there is a change in change in the season, it will change with a brown or gray color that covers it when the coat or coat is also under rock or plants. This dyeing benefits you, helps to hunt rodents, birds, and fish.

What are adaptations in arctic foxes?

Arctic foxes have several adaptations to survival. The round and compact body minimizes the surface area exposed to cold air. Their noses, ears, and feet are short and warm.

Hence it concludes that phenotypic plasticity in arctic foxes causes different colored fur to grow.

A. 1.9 mL to 8.7 mL
B. 0.0 mL'to 21 mL
C. 3.1 mL to 8.7 mL
D. 0.1 ml

Answers

Answer:a

Explanation:

1.9 mL to 8.7 mL is the range for the following set of measurements which are 3.1 mL, 2.7 mL, 4.6 mL, 1.9 mL, and 8.7 mL. Therefore, the correct statement is option A.

What is the range?

The range is the difference between the highest and lowest values in a given set of measurements. The range can be calculated from a given set of measurements by subtracting the lowest value which is 1.9 mL and the highest value which is 8.7 mL, thereby, giving a range of 6.8 mL.

In the given set of measurements which are 3.1 mL, 2.7 mL, 4.6 mL, 1.9 mL, and 8.7 mL, 1.9 mL to 8.7 mL is considered to be the range.

Therefore, 1.9 mL to 8.7 mL gives the range of lowest and highest values present in the given set of measurements. However, the range of values cannot be negative and represents the highest and is only represented by the lowest values and highest values in the set.

Therefore, in the 3.1 mL, 2.7 mL, 4.6 mL, 1.9 mL, and 8.7 mL set of measurements, 1.9 mL to 8.7 mL is the range.
