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

Answer:

We eat because we are sad and deprived of love. That one compliment you got from 5 years ago from a girl? Yeah, you still remember that don't you? Well, guess what, now she's married to a guy more handsome than you. When she gave you that compliment, she forgot about it a day later. Why are you still holding on? Eating tubs of icecream any crying yourself to sleep will do no good. Time to pack it up Nickocado Avocado.

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.

Classification of Living Things Notes

1. An organism is a living thing.

2. Characteristics of all living things:

1) Organisms obtain and use resources.  All organisms must obtain resources, such as food and water, which provide required energy to perform the basic processes of life, like growing, developing, and repairing injured parts.  

2) Organisms respond to stimuli:  A stimulus is any change in an organism’s surroundings that will cause the organism to react. Examples of environmental stimuli include changes in the amount of light present, changes in temperature, sound, amount of water, space, amounts of food present. The reaction to the stimulus is called a response. It can be an action or behavior performed by the organism.

3) Organisms reproduce-produce offspring that have similar characteristics as the parents. Reproduction can occur in one of two ways:

a) Asexual reproduction involves one parent that makes an exact copy of itself. The offspring are identical to the parent.

b) Sexual reproduction involves two parents. Sperm cell from the male and egg cell from the female combine to produce offspring that have characteristics from each parent.

4)  Organisms grow and develop. Growth is the process of an organism becoming larger. Development is the process that occurs during the life of an organism that results in the organism becoming more complex. Organisms require energy to grow and develop.

3. Classification is the process that scientist use to arrange organisms into groups based on the shared observable characteristics.

4. Taxonomy is the science of identifying and classifying organisms into groups.

5. A taxonomist is a scientist who identifies and names organisms based on their similarities and differences.

6. Taxonomist use physical characteristics as well as DNA, genetic information, to classify organisms.

7. Scientist all over the world study organisms, in order to avoid confusion scientists need a universal way of naming organisms.

8. A dichotomous key is a tool used to identify organisms. It uses a series of questions, each with only 2 answers.

9. Linnaeus developed a system for classifying organisms called binomial nomenclature.  It uses two Latin words to name an organism. The name is made up of the genus and species of the organism.  The name is written in italics, the genus is capitalized, and the species is lower case; for example, the scientific name for a human is Homo sapiens.

10. The Linnaeus system is made up of seven levels, Kingdom, Phylum, Class, Order, Family, Genus, and Species.

1) King Philip Could Only Find Green Socks is one mnemonic way to remember the order of the levels. Another is King Philip Came Over For Good Spaghetti.

2) The levels are arranged from the most broad, Kingdom, to the most specific, Species.

11. Kingdom- organisms are placed into kingdoms based on their ability to make food and the number of cells in their body.

12. Phylum (phyla is plural)- In the Plant Kingdom, phyla are sometimes called divisions. In the Animal Kingdom, there are 35 different phyla.  

13. Class, Order, Family-these levels become even more specific. Each level has fewer organisms that have more in common with each other as you move down the levels.

14. Genus- contains closely related organisms. The genus is the first word in an organism’s scientific name.

15. Species- consists of all the organisms of the same type which are able to breed and produce young of the same kind. The species is the second word in an organism’s scientific name.

16. Most scientists classify organisms into 5 kingdoms: Plants, Animals, Protists, Fungi, and Monera.  

1) Plants (Plantae)- the plant kingdom is made up of plants. Plants are autotrophs, they make their own food. Plants are eukaryotes; they are made up of many cells. Plants are divided into 2 groups: vascular and nonvascular.

2) Animals (Animalia)- the animal kingdom is made up of animals. Animals are heterotrophs- they must obtain food by eating it. Animals are eukaryotes. The 35 phyla are divided into two groups: vertebrates and invertebrates.

3) Fungi- the fungi kingdom is made up of molds, yeasts, and mushrooms. Fungi are heterotrophs because they must absorb their food. Yeasts are one celled, while molds and yeasts are eukaryotes. Their cells have a nucleus, a cell wall, and no chlorophyll. Most fungi are decomposers, they break down dead organisms.

4) Protists (Protista)- the protists are made up of organisms that cannot easily fit into the plant, animal, or fungi kingdoms. They are one celled organisms with a nucleus or simple multicelled organisms. Some protists are autotrophs, some are heterotrophs.

5) Monera- the Monera kingdom is made up of bacteria. Their cells do not contain a nucleus. Some bacteria are autotrophs, some are heterotrophs.

Answer: B. Primary Succession

Decomposers are organisms that break other organisms down and return nutrients back to the soil. Therefore, they also recycle organic matter back to the environment, making choice 2 the correct answer choice.

Answer:

True

Explanation:

As has been stated, carbohydrates are the most-important direct organic product of photosynthesis in the majority of green plants using H20 and Co2. The formation of a simple carbohydrate, glucose.

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

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.

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.

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.
