The cell is eukaryotic because it contains mitochondria is the best line to define eukaryotic cells. Therefore, option "D" is correct.
What is eukaryotic cells?Eukaryotic cells are large, intricate organisms with a nucleus enclosed within the nuclear membrane. Eukaryotic cells can be found in animals, plants, protozoa, and fungi.
In prokaryotic cells, the cytoplasm is available, however, it is deficient in most cell organelles. It comprises both organelles and cytoplasm in eukaryotic cells, and both are present. There are mitochondria, which are the cells' powerhouse. There are two kinds of organelles present which is membrane-bound and non-membrane-bound.
Therefore, eukaryotic cells are also referred to as true cells having membraned nuclei.

Hi guys does anyone have notes for lesson characteristics and classification of living organisms? Also I need some questions so that I can be prepared for the test
Answer:
Explanation:
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.

Passive transport is the movement of substances across a cell membrane without the use of
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.

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.

why does the structure of a protein depend on the sequence of the DNA?
Answer:
Explanation:
The Rules of Protein Structure. The function of a protein is determined by its shape. The shape of a protein is determined by its primary structure (sequence of amino acids). The sequence of amino acids in a protein is determined by the sequence of nucleotides in the gene (DNA) encoding it.
2. Identify two functions of plastids in plant cells.
Plastids. Plant plastids are a group of closely related membrane-bound organelles that carry out many functions. They are responsible for photosynthesis, for storage of products such as starch, and for the synthesis of many types of molecules that are needed as cellular building blocks.
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

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.

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.
