A scientist wants to examine a genetic disease in humans. The scientist hypothesizes that the disease can be treated by using gene therapy. Humans take a long time to reproduce and develop, so the scientist will have to
give up on testing the hypothesis.
test the hypothesis for a very long time.
develop new methods to test the hypothesis.
find a way to make humans reproduce faster.
Answer:
C. Develop new methods to test the hypothesis.
Explanation:
Edge 2020
A scientist will have to develop new methods to test the hypothesis as a
result of humans taking long time to reproduce.
Hypothesis is an explanation for an occurrence or phenomenon in research.
It involves conducting different tests under the same and varying conditions
to confirm if the hypothesis is true which then becomes a law when
universally proven.
Testing of hypothesis is very important which is why developing new
methods which has a lesser time frame to test the hypothesis and not
quitting will be the best option.

A large number species on Earth become extinct during a short time period about 65 million years ago. Based on this pattern of extinction, which is the MOST likely cause
Answer and Explanation:
During the whole biota history, there occurred extinctions due to different reasons.
During the Cretaceous, which took place between 145-65 million years ago, there occurred a massive extinction that eliminated most of the species on the Earth. Many of the characteristic groups of this period were affected. Dinosaurs, Plesiosaurs, Ammonites, Tricodonts, Cycas, Gynkgos, Conifers, the recent angiosperms, birds, and mammals.
The extinction was caused by the volcanic eruptions, and the unusual fall of many different asteroids, which caused important changes on the Earth´s surface. The consequent climatic change was what ended affecting all the species directly. The extinction was gradual, although it occurred in a short geological lapse of time.

3(a). Diagram 3 shows some processes that involve the changes in the
state of matter. Choose the processes that release heat.*
Answer:
C
D
Explanation:
The processes of freezing sublimation releases heat to environment.
Freezing is a phase change by which a liquid changes to solid.
Sublimation is a phase change in which a gas changes to solid.
Phase changes by which a substance returns back to the state of orderliness involves a loss of heat. Sublimation is can be from solid to gas or gas to solid. In the process from gas to solid, heat is released. But from solid to gas, heat is absorbed.Which of the following best describes how meiosis helps maintain genetic variation?

There are only three autosomal trisomic conditions (Patau, Edward, and Down Syndrome) where a fetus will survive to birth. Why do you think this is so?
Answer:
An autosomal trisomic condition is the deviation of the chromosome number where an extra copy of the chromosome present with the chromosome pair. The three trisomic conditions are Patau - extra copy at chromosome 13, Edward - extra copy of chromosome 18, and Down Syndrome - an extra copy of chromosome 21
Children or fetuses affected by these trisomies show the least life expectancy and develop as mentally week, other than these trisomies other trisomic conditions are highly lethal so we do not see the survivors and it is due to dosage sensitivity which means that increasing or decreasing their expression levels will reduce cell viability.

The DNA sequence that makes up the genetic code of an organism determine which traits the organism will exhibit
Answer:
How are the instructions coded by DNA translated into an organisms physical traits. They are translated into proteins which express an organism's physical traits. In DNA, the structure and size of the four nitrogen bases allows only for one kind of base to pair with one other kind. This is called the base-pairing rule.

How are the krebs cycle and the electron transport chain related?
A sports medicine major wants to conduct a experiment to determine if there there's a correlation between the members of the soccer team's leg strength and the time it takes for them to sprint 40 yards. He sets up the following test and records the data:
Every day for a week, he counts how many times each player can leg press 350 pounds. The following week, he has each player sprint 40 yards every day. The table shows the average number of leg-press repetitions and the average 40-yard dash time (in seconds) for seven randomly selected players. What is the equation of the line best fit? How many seconds should he expect a player to take to run 40 yards if that player can do 22 leg-press repetitions? Round any values to the nearest tenth, if necessary.
leg press (reps) 12 | 32 | 7 | 11 | 23 | 28 | 15 |
40-yard dash (s) 8.6 | 14.6 | 7.1 | 8.3 | 11.9 | 13.4 | 9.5 |
Answer:
The correct answer is the equation of the line of best fit is y=0.11x+4.54, and it would take the player 6.96 seconds to run.
Explanation:
Using technology, we calculate the line of best fit; we first enter the data points as a scatter plot, then run the regression tool, which gives us y=ax+b, where a=0.11 and b=4.54.
We now use this equation, y=0.11x+4.54, to calculate the amount of time it would take a player to run 40 yards if the player can do 22 leg-press reps:
y=0.11(22)+4.54=6.96.

ment is always true of work?
A) It is difficult.
B) It involves levers.
C) It involves a transfer of energy.
D) It is done with a machine.
Answer: C. It involves a transfer of energy.
Using the scientific definition, the statement that is always true of work is it involves a transfer of energy. The correct option is C.
What scientific theories?Scientific theories are the theories that are given by scientific facts and information. These theories are based on observation of natural things and places.
There is the transfer of energy in the natural world. Every organism and plant is connected with each other in the form of a transfer of energy. This is called a food chain.
In the food chain, the organism is divided into different levels. These levels are based on their food. They are autotrophs, heterotrophs, and decomposers. Autotrophs have the largest amount of energy.
Thus, the correct option is C) It involves a transfer of energy.

which of the following correctly describes the induced fit process of how enzymes work
1.the substrate binds and the enzyme split apart prior to actiong on the substrate
2. the substrate binds and the substrate changes changes shape and then substrate is acted upon by the enzyme
3. the substrate binds and is immediatelyacted upon by the enzyme
4. the substrate binds and the enzymes changes shape and then the substrate is acted upon by the enzyme
Answer:
The correct answer would be number 2
Explanation:
The correct description of the induced fit process of how enzymes work is;
The substrate binds and the substrate changes shape and then substrate is acted upon by the enzyme ( 2 )In an Ideal fit model for catalysis, the substrate will bind to a site ( active ) and the substrate bond to the site will change its shape before been acted upon by the enzyme to form a complex ( enzyme- substrate ).
The enzymes ( biological catalyst )does not change shape permanently during the reaction process but it returns to its original shape after the reaction ( end of reaction )
Hence we can conclude that correct description is the substrate binds and the substrate changes shape and then substrate is acted upon by the enzyme.

Which is the process by which gas exchange between the respiratory system and the blood cells in the cappilaries occurs? transfusion condensation evaporation diffusion
Answer:
Diffusion
Explanation:
Diffusion is the process by which molecules of substances move from regions of higher concentration to regions of lower concentration until equilibrium concentration is attained. This movement of molecules is because a concentration gradient exists between the two regions.
Blood cells in the capillaries is low in oxygen because the cells have used up the oxygen in cellular respiration. However, in the lungs, the oxygen concentration is high due to inspiration of oxygen from the external environment. Therefore, a concentration gradient exists between the lungs and blood cells in the capillaries. Oxygen from the lungs diffuses into the blood cells in the capillaries, and these blood cells are then returned to other parts of the body by the circulatory system. This is a continuous process and is known as gaseous exchange.
Answer:
Diffusion
