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.

How long ago do scientists believe the continents formed Pangaea?
about 135 million years ago
about 180 million years ago
about 300 million years ago
about 4.5 billion 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.

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?
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.

In general, what types of substances tend to be acidic
Answer:
- Any pH on the pH scale that tends to be less than a 7 is an acidic substance. (Examples like:Lemon juice and vinegar)
The types of substance that is tends to be acidic are substance with PH lower than 7.
An acid can be regarded as molecule that can donate protons, this us referred as Brønsted–Lowry acid, or that can produce a covalent bond with an electron pair i.e Lewis acid. One of the properties of acid is that it turn blue litmus paper to red, and has a sour taste.To determine an acid, pH scale is helpful.pH scale can be regarded as one used to to determine the acidity or basicity of an aqueous solution. Acidic solutions are one with pH of (0-6), while alkaline has pH of (8-14) on this scale.Examples of acids substance are;
inorganic substances such as sulfuric and nitric, hydrochloric, organic compounds such as carboxylic acid, sulfonic acidTherefore, substance with lower pH are regarded to be acidic.

true or false: plants release energy as ATP during cell respiration and use it for maintenance and growth
Answer: The outcome of cellular respiration is that the plant takes in glucose and oxygen, gives out carbon dioxide and water and releases energy. Plants respire at all times of the day and night because their cells need a constant energy source to stay alive.

Answer:
Image result for Passive transport is the movement of substances across a cell membrane without the use of
Passive transport is a movement of ions and other atomic or molecular substances across cell membranes without need of energy input. Unlike active transport, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in entropy.

When snow covering the ice sheet blow away, there is an increase in oxygen bubbles trapped under the ice. Explain why this occurs
Answer:
Impurities are trapped between layers of ice over the years.
Explanation:
As time goes on, many chemical impurities and gases are trapped between deposits of ice that form over the years in extremely cold regions such as Antarctica.
When the snow covering these layers of ice are removed, the gases trapped underneath are released and more oxygen dissolves in the ice and more bubbles are observed.

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. The bride’s parents chose whom the bride would marry when the girl was very young.
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.

Determine the stimulus, receptor, control center response and effector for gas exchange for plants.
I put slides to help find the answer Please help me!!
Answer:
The exchange of oxygen and carbon dioxide in the leaf (as well as the loss of water vapor in transpiration) occurs through pores called stomata (singular = stoma). Normally stomata open when the light strikes the leaf in the morning and close during the night.
Stomata (the receptors of gas exchange process) are tiny holes found in the underside of leaves. They control water loss and gas exchange by opening and closing. They allow water vapour and oxygen out of the leaf and carbon dioxide into the leaf. In low light the guard cells lose water and become flaccid, causing the stomata to close
