Answers

Answer:

Kindly check explanation

Explanation:

According to the graph given the number of algae is represented on the y axis while the month of the year is represented on the x - axis of the graph. The change in the number of algae from February is clearly depicted by an upward slope along the y-axis which means that there is continous increase in the Number of algae in the lake during this period, that is between February to June . It could also be seen that around June the optimal number of algaae is achieved as the number of algae tend to fall as we move beyond June.

C.
It’s attributed to natural environmental changes.
D.
It’s necessary for evolution.
E.
It’s affecting few species.

Answers

Answer:

its b

Explanation:

Extinction is primarily attributed to human intervention. So, the correct option is B.

What is Extinction?

The extinction is defined as the end of a particular type of organism or a set of types, typically a species. Although the ability to reproduce and bounce back may have been lost earlier, the death of the last member of the species is usually considered as the moment of extinction.

Extinction is the term used to describe the extinction of an entire species. In that it has allowed for the emergence of new species and the ascent of others, extinction has both advantages and disadvantages. Since most species have been driven to extinction by human activity, humans have had a significant impact on the pace of extinction. The main cause is thought to be human activity.

Therefore, the correct option is B.

Answers

UGA CGU, the complimentary DNA strand would be the mRNA stand

The complimentary DNA strand for the sequence ACT GCA is TGA CGT​.

What is DNA?

DNA stands for deoxyribonucleic acid which is defined as a polymer made up of two polynucleotide chains which coil around each other to form a double helix.

Primarily DNA is located in the cell nucleus called nuclear DNA, but a small amount of DNA can also be found in mitochondria called mitochondrial DNA or mtDNA, so mitochondria are structures within cells that store energy from food that converts into energy.

The information in DNA is stored in the form of code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T) which are bond to each other by hydrogen bond like A with T with 2 hydrogen bonds while C with G with 3 hydrogen bonds. Like for above given information,  ACT GCA complimentary strand is TGA CGT

Thus, The complimentary DNA strand for the sequence ACT GCA is TGA CGT​.

The best method for randomly determining how many eggs an imaginary bird lays in a simulation would be to roll a six-sided number cube and use the number on the top side. Therefore, option (D) is correct.

What is a simulation?

A simulation is a computer program or model that imitates a real-world system or process. It allows researchers, scientists, engineers, or other users to understand, predict, or test the behavior of a system or process under different conditions or scenarios. Simulations are used in various fields, including engineering, physics, chemistry, economics, medicine, and social sciences, among others.

They often involve mathematical or statistical models, algorithms, and computer graphics or visualizations to represent the system or process being simulated. By running a simulation, users can observe the results, draw conclusions, and make predictions about the behavior of the real-world system or process. Simulations can be helpful in decision-making, experimentation, training, and education, among other applications.
