If a car has a mass of 700kg and a driver pushes the car with an acceleration of 0.05m/s/s; what is the force?
Answers
Answer:
35 N
Explanation:
The formula to calculate force is:
F= m*a
So, the mass is 700 kg, and the acceleration is 0.05 m/s.
Simply multiply 700 kg* 0.05 m/s and you get 35 N.
The reason why it is newtons(N) is because that is what force is measured in.

Why do scientist study ice cores
Select all that apply
To study Earth's past climates
To study how Earth's climate is changing now
To study how climate typically stays the same
To study how it might change in the future
Answers
Answer:
to study earth's past climate
Answer:
Explanation:
Air bubbles and dust get trapped in ice as it forms. And the ice in some places, like Antarctica, has stayed frozen for over a million years. Scientists drill holes in the ice and remove ice cores. Each year's worth of ice forms a layer within the core.
The material trapped in ice layers gives information about the climate at that time. Scientists study the layers to learn about past temperatures and precipitation. They can learn how the amount of carbon dioxide in the atmosphere has changed over time. The layers also reveal when events such as volcanic eruptions have taken place.

Limiting factors in water bio mes include
amount of salt
amount of dissolved oxygen
amount of sunlight
all of the above
Answers
Answer:
all of the above
Explanation:
Water biomes describe all the living things living in an area of water such as a lake or ocean. The surrounding environment plays a huge part in what organisms able to live there.
For example, green plants and algae require sufficient sunlight and oxygen to perform photosynthesis. Green plants and algae are an important food source for many other organisms. The amount of salt is important for various fish, as they will be unable to survive in very high salt concentrations. Therefore, all of the above are limiting factors.
Ecological success is valuable to understand, because it can change the biodiversity within an ecological community. Being able to teach a topic to a peer can demonstrate mastery! Explain the sequence of events that occur in secondary succession as you would to a friend who had not yet learned about the process.
Answers
Answer:
Secondary succession is a process in which a given area is disturbed, being re-colonized by other organisms following this process.
Explanation:
Secondary succession steps:
1- An area suffers a disturbance (e.g., fire, flood, earthquake, etc).
2-The process of disturbance destroys the food chain by removing primary producers (e.g., plants)
3- The vegetation grows back (i.e., first grasses and after higher trees). This process is known as recolonization
The secondary succession can regenerate an ecosystem in less than 50 years after disturbance. The first species re-established during secondary succession are the animals capable of living in disturbed habitats.
Secondary succession refers to the re-grow of species and the establishment of new ones in areas where a perturbation occurred leaving fertile good soil.
---------------------------------
Succession is a term used to refer to colonization and subsequent changes.
Colonization drives the establishment of individuals, populations, species, or bigger groups in areas where they were absent before.
When talking about succession, we refer to changes produced in the composition and structure of communities after a perturbation.
When a perturbation occurs -like fires, floods, earthquakes- and removes part or all of the aerial vegetable life forms, we talk about secondary succession.
In secondary succession, after the perturbation occurrence, the soil remains good and fertile, carrying viable spores, seeds, and roots of surviving species.
With time these species emerge and re-grow, colonizing the area. Also, new species can arrive at the open space, establishing there for the first time.
So, step by step,
1) A perturbation must occur in a community.
2) The perturbation damages or eliminates aerial parts of vegetable species. But the soil, which remains fertile, managed to protect seeds, spores, and roots of the species that used to live in these areas.
3) With time, these species regrow, and new species arrive in the area.
4) A new community emerges.

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
Answers
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.

Answers
Answer:
A.
Explanation:
The zones of the ocean which is most hospitable to life is the epipelagic zone. Thus, the correct option will be A.
What is the epipelagic zone?The Epipelagic zone can be referred to as the uppermost layer of the ocean. Epipelagic zone is located between the surface and the 600 feet in depth of the ocean. The Epipelagic Zone is also known as the Sunlight Zone. It is the region of the ocean which sits on the continental shelf in the oceans.
Epipelagic zone is in this thin layer which the process of photosynthesis takes place. The epipelagic zone of the ocean only represents about 2 to 3% of the entire ocean zone, beyond this zone, light is too dim for the process of photosynthesis to occur. This is the reason why, the epipelagic zone is the most hospitable zone of the life in oceans.
