about 4.5 billion years ago

Answers

About 300 million years ago

The scientists believe the continents formed Pangaea about 300 million years ago. The correct option is C.

What is Pangaea?

According to National Geographic, the Pangaea theory proposed that the tectonic plates that make up the planet's external crust glided over the inner layers until they consolidated as a landmass encircled by a huge ocean called Panthalassa.

After a while, the Angaran continent near the North Pole began to move south and combined with the northern part of the expanding Euramerican continent, forming the Pangea supercontinent. This process was completed approximately 300 million years ago.

Alfred Wegener observed the same thing in 1912 and proposed that the continents were once scaled down into a single protocontinent known as Pangaea.

Thus, the correct option is C.

Based on this excerpt, what is most likely true about ancient Greek marriage rituals? The groom had to perform a brave feat before marrying the bride. The groom had to ask the bride’s parents for permission to marry her. The bride’s parents made all the arrangements for the couple’s marriage ceremony.

Answers

Answer:

The correct answer is:

The groom had to ask the bride’s parents for permission to marry her.

Explanation:

Marriage in ancient Greek was less of a personal relationship than it was a social relationship. Asking a parent or guardian by the groom for permission to marry the bride is a tradition that spans several cultures and was also evident in ancient Greek marriage rituals. The permission is usually given by the father, and once that happens, the couple is officially engaged. Marriages were also arranged through the meeting of the fathers of the young couple, basing the marriage on their interests in expanding a business or forging an alliance between the families, with little concern about what the groom thought of the situation, and no regard for what the wife wished

Answer:

B. The groom had to ask the bride's parents for permission to marry her.

If the strand of DNA being used is A A A T A A G C G C C A, what is the messenger RNA strand that will be produced?

Answers

Answer: UUUAUUCGCGGU

Explanation: Remember the base pairing rules: cytosine with guanine and adenine with uracil. To compliment the given strand, you'd have to choose the base that would pair with each individual nucleotide. Since mRNA has no thymine, the adenine must pair with uracil instead. However, it does have adenine to pair with the thymine, even if it doesn't have any of its own.

Answer:

Impurities are trapped between layers of ice over the years.

Explanation:

Asexual Reproduction occurs when there is only one parent that gives rise to an offspring which has the identical genetic makeup of the parent. It occurs in most single celled organisms such as bacteria and some multicellular organisms such as fungi and some plants. Some advantages of asexual reproduction are it is fast and efficient. It does not require a male and a female. Organisms can reproduce quickly! A disadvantage is that there is no genetic diversity and it can only be done by simple organisms.

Sexual Reproduction involves the combining of genetic information from two parents to produce a new organism that is a combination of both parents. It occurs in most complex organisms. Some advantages to sexual reproduction are that it creates genetic diversity. It allows for evolution of the species. A disadvantage is that it requires two organisms to reproduce, a male and a female. It also requires more energy than asexual reproduction.

Using the table below, list at least two advantages and disadvantages of Asexual and Sexual Reproduction.

asexual reproduction sexual reproduction:
advantages: advantages:

disadvantages: disadvantages:

Answers

Sexual reproduction:
Advantages: A species can evolve or adapt to changing environments, genetic diversity
Disadvantages: Time and energy needed to find a mate, requires both male and female gametes, one individual cannot reproduce

Asexual reproduction:
Advantages: Only one individual is needed to reproduce, doesn’t require time or energy to find a mate, can reproduce rapidly in good conditions
Disadvantages: No genetic variation, all of the offspring have the same weaknesses, can’t adapt or evolve
