Answer:
4.
Explanation:
Everyone's DNA is unique unless they are identical twins or if you have some kind of transplant.
Of the following best explains why DNA fingerprints can be used to identify an individual, such as from a crime scene sample it is the situation that Each individual has a unique DNA sequence, with the exception of identical twins. The correct answer is option 4.
What are identical twins ?These are the babies that are formed from multiple fusion of gametes and resulting into double fertilization.
DNA is inherited from both maternal and paternal parents. Yes, it is so but the pattern is not same as it will be possible to get the idea of the pattern and analyse along with the prediction of the genome as only few % is predicted.
DNA is used to make proteins during protein synthesis and this situation is clearly correct too but the fact is that this is not helping in the case of DNA fingerprinting where it is not easy to firstly see the DNA pattern then the RNA and then the amino acids and then the proteins.

compare the reproductive strategies of a short lived species such as a starfish and a long lived species such as a hippopotamus
Answer:
Starfish reproduce every winter by ejecting there eggs into the water, since they only live on average 35 years they reproduce about 35 times in their lifetime. Only a couple of the eggs will fertilize and turn into a Starfish.
Hippos are the only mammals in Africa that reproduce in water, Hippos reproduce in May and through June. Hippos usually live to around 40 to 50 years, and most hippos through May and June reproduce more than one time.
Explanation:
Hippos strategies of reproducing are better than Starfish.
Amylase becomes denatured at a temperature of 80c. During an experiment to study the effect of varying temperatures on enzyme activity, amylase's reactivity with starch was measured at a body temperature of 37c and then again at an increased temperature of 42c. How would this increase in temperature affect the experiment?
Answer:
The rate of reaction will increase
Explanation:
Temperature is known to affect the rate of the reaction. Generally, chemical reactions depend on thermal activation. It means that an increase in temperature also increases the kinetic energy of the reactants. Increasing the temperature increases the reaction rate due to the increase in the number of molecular collisions between reactant molecules. The speed of a particle is directly related to its kinetic energy and thereby an increase in temperature also results in an increase in the amount of collisions between molecules per unit of time.
Which of the following is an optional part of a technological system?
output
input
feedback
process
Answer:
Feedback
Explanation:
A technological system is a system that consists of components constructed to work together in order to process an input to an output/result. These components or parts that make up a technological system are as follows: input, processing, output and feedback.
- The input is what is taken in by the system.
- The process is the series of occurrences conducted by the internal parts of the system to bring about an output.
- The output is the final result of the system.
- The feedback is how the system should work in comparison to how it is working.
Among all these parts of a technological system, the part that is OPTIONAL i.e the system can function without, is the FEEDBACK.

What is the force of an object if it accelerates 4 m/s2 and has a mass of 10 kg? (F = ma)
A.
0.4 Newtons
B.
2.5 Newtons
C.
40 Newtons
D.
100 Newtons
Answer:
C. 40 Newtons
Explanation:
We are given the equation to calculate force:
Force=mass×accelleration
To find the answer, we just need to plug the given mass and acceleration into the equation. The units of these values are typically kg and m/s^2 when calculating the force in Newtons, which they already are (so we don't need to do any conversion).
Mass=10kg
Acceleration=4 m/s^2
F=ma
F=10×4
F=40 N
Therefore, the force of the object is 40 Newtons.

Which kind of organism is an autotroph? consumer producer decomposer herbivore
Answer:
Producer
Explanation:
An autotroph is a type of organism that is capable of producing its own food from inorganic substances. The correct answer is "producer."
Describe autotroph.Autotrophs utilize various processes to convert energy into usable forms. The most common and well-known method is photosynthesis, which involves capturing sunlight and using it to convert carbon dioxide and water into glucose (a type of sugar) and oxygen. Plants, algae, and some bacteria are examples of autotrophs that perform photosynthesis.
They are often referred to as producers because they can convert energy from sunlight (or other forms of energy) into organic compounds through processes like photosynthesis or chemosynthesis.
Autotrophs, such as plants, algae, and some bacteria, are able to synthesize their own nutrients and energy sources, typically using sunlight, water, and carbon dioxide. They form the foundation of food chains and provide energy for other organisms in ecosystems.
Therefore, the correct answer is "producer."

Anaerobic respiration is also known as?
Answer:
Intramolecular respiration
Explanation:
I think sorry if i'm wrong
It is also called as the fermentation. It is the kind of respiration which helps the cells to breakdown energy in the absence of oxygen.
What is the other type of respiration called as ?It is called as the aerobic respiration which takes place in the presence of oxygen.
Anaerobic that stands for without oxygen.This is the method of the cellular respiration where it does not basically require the oxygen in order to generate the energy. For the smaller animals for breathing , here is no enough oxygen present so that they will need energy for surviving in absence of oxygen.
Anaerobic respiration is the process in which the cells just break down into sugars just to produce out energy in the absence of oxygen. The respiration is called as fermentation. it mainly takes place in yeast cells, bacteria, and muscle cells of animals.
