Please :( Based on your knowledge of evolution, are humans evolving? Support your answer with factual evidence as to
why or why not

Answers

Answer:

Jesus made every one evalution is false

When Charles Darwin introduced the theory of evolution through natural selection 158 years ago, the scientists of the day argued over it fiercely, but the massing evidence from paleontology, genetics, zoology, molecular biology and other fields gradually established evolution's truth beyond reasonable doubt. Today that battle has been won everywhere—except in the public imagination. Embarrassingly, in the 21st century, in the most scientifically advanced nation the world has ever known, creationists can still persuade politicians, judges and ordinary citizens that evolution is a flawed, poorly supported fantasy. They lobby for creationist ideas such as “intelligent design” to be taught as alternatives to evolution in science classrooms. When this article first went to press in 2002, the Ohio Board of Education was debating whether to mandate such a change. Prominent antievolutionists of the day, such as Philip E. Johnson, a law professor at the University of California, Berkeley, and author of Darwin on Trial, admitted that they intended for intelligent-design theory to serve as a “wedge” for reopening science classrooms to discussions of God.

The good news is that in 2005 the landmark legal case Kitzmiller v. Dover in Harrisburg, Pa., set binding precedent that the teaching of intelligent design in U.S. public schools is unconstitutional because the idea is fundamentally religious, not scientific. The bad news is that in response, creationists have reinvented their movement and pressed on. When they lost the ability to claim that creationist ideas are valid science, they switched to arguing that they were only supporting “academic freedom.” Worse, to further obscure the religious roots of their resistance, they now push for “critical analysis” of climate change, cloning research and other scientific endeavors that they paint as culturally oppressive.Explanation:

Point mutations resulting in a single amino acid substitution provided evidence that: Select one: A. The genetic code is a triplet code. B. The genetic code is overlapping. C. The genetic code is not overlapping. D. The genetic code is degenerate. E. tRNAs recognize codons.

Answers

Answer:

C. The genetic code is not overlapping.

Explanation:

The genetic code is nonoverlapping because each nucleotide can be part of only one codon or 'codeword' during protein synthesis. Therefore, a particular point mutation in the nucleotide sequence can result in only one amino acid modification. A nonoverlapping genetic code indicates that the same letter (i.e., the same nucleotide) can not be used for two different codons. The non-overlapping nature of the genetic code was discovered by Tsugita and Fraenkel-Conrat (1960) by observing point mutations in the tobacco mosaic virus.

A change or modification in the single nucleotide base of the genetic material is called a point mutation. It can be either addition, deletion or inversion.

The correct answer is:

Option C. The genetic code is not overlapping.

This can be explained as:

The point mutation in the amino sequence tells that the codons are not overlapping and a single nucleotide is a part of only a single type of codon.

A single nucleotide can't be included in two codons.

The same letters of the bases purines and pyrimidines are not a part of two different triplets.

Therefore, point mutation tells that the genetic code is non-overlapping.

Which statement best describes the evolution of hominid structure over time?
The size of the skull decreased.
O The size of the brain cavity increased.
O The shape of the head became flatter.
The shape of the teeth became more pointed.

Answers

Answer:

The size of the brain cavity increased.

Explanation:

Over the years the brain cavity got bigger  and so did our brain and that is why humans are smarter

The evolution of hominid structure over time involved the increase in the size of the brain cavity.

What is evolution?

Evolution refers to the gradual and cumulative changes that occurred in organisms over a long period of time which made them more complex and which they were able to transmit to their offspring.

The hominids were the ancestors of the modern day humans.

Through the process of evolution, the size of the brain cavity increased in hominids resulting in larger brains and more complexity as seen in modern humans today.

Therefore, the increase in the brain cavity of hominids occurred through the process of evolution.

The area of the picture highlighted by the green square is a monomer of nucleic acids(DNA/RNA). Which of the following is the name for that monomer?

A. phosphate backbone
B. thymine
C. nucleotide​

Answers

Answer:

C. Nucleotide

Explanation:

There are four types of biological molecules existing in nature. These are: carbohydrates, proteins, lipids, and nucleic acids. Nucleic acids are biological polymers made up of monomeric units called NUCLEOTIDES.

A nucleotide as depicted in the attached image is a molecule made up of three components namely; Penrose sugar, phosphate group, and nitrogenous base (adenine, guanine, cytosine and thymine). Based on the image in this question;

A represents ADENINE

S represents SUGAR

P represents PHOSPHATE GROUP

Hence, the monomer is a NUCLEOTIDE.

Answers

Answer:

dna could be used for food by bacteria

Explanation:

not a beneficial reason

All of the following reasons are beneficial for prokaryotes to take up foreign DNA except the use of DNA as food by bacteria. Thus, the correct option is A.

What is DNA uptake?

DNA uptake is defined as the conversion of exogenous, DNase-sensitive DNA into a DNase-protected state inside a bacteria. In gram-negative bacteria, this DNA uptake can be achieved by crossing the outer membrane. By contrast, in gram-positive bacteria, DNA uptake is similar to gram-negative bacteria with passage across the cytoplasmic membrane.

The uptake of DNA in bacteria is beneficial as it helps in the production of recombinants that can be used for various purposes. The DNA uptake can be used for the repairing of damaged DNA and chromosomes in patients of genetic disorders.  

New genes with different functions can be introduced in organisms like bacteria.

Therefore, the correct option is A.

B. Energy is transferred from the cooler air to the warmer ground.

Explanation:

When cooler air particles come into contact with the warmer ground, energy is transferred from the cooler

air to the warmer ground.

Answer: The temperature of air would decrease.

Explanation:

The energy gets transferred from hot object to cold object until the two objects are in thermal equilibrium. When air transfers energy to a cooler object, it means the air it self is cooling down till the air and the object are in thermal equilibrium. Thus, the temperature of air would decrease.

4. Free or low-cost apps have few of the same benefits as fitness trackers.
True
False

Answers

The given statemnet is false because  Free or low-cost apps can provide many of the same benefits as fitness trackers, albeit with some limitations.Option B

Fitness trackers are dedicated devices designed specifically for monitoring physical activity and collecting data related to fitness goals. They often include features like step counting, heart rate monitoring, sleep tracking, and GPS tracking. These devices may offer a more seamless and integrated user experience, with optimized hardware and software for tracking and analyzing fitness data.

However, free or low-cost apps can offer similar benefits and functionalities, albeit with some trade-offs. Many smartphone apps are available that can track steps, monitor heart rate, record workouts, and provide guidance for various exercises. These apps can be downloaded and installed on smartphones, making them accessible and convenient for users.

While some features might be more accurate or reliable in dedicated fitness trackers due to specialized sensors, smartphone apps can still provide valuable data and insights for tracking fitness progress. They can offer personalized workout plans, track progress over time, provide reminders and notifications, and offer social features for sharing achievements and connecting with others.

Moreover, free or low-cost apps often come with the advantage of being customizable, allowing users to choose the features and functionalities that are most relevant to their specific fitness goals and preferences. They can be easily updated and expanded with new features as technology advances.

In conclusion, while dedicated fitness trackers may offer a more comprehensive and optimized experience, free or low-cost apps can still provide many of the same benefits, making them a viable alternative for individuals seeking fitness tracking capabilities.
