All living things have internal that helps them carry out basic functions.​

Answers

true

................................

Answer 2

Answer:

True

Explanation:

By the end of grade 2. All organisms have external parts. Different animals use their body parts in different ways to see, hear, grasp objects, protect themselves, move from place to place, and seek, find, and take in food, water and air. Plants also have different parts (roots, stems, leaves, flowers, fruits) that help them survive, grow, and produce more plants.  

By the end of grade 5. Plants and animals have both internal and external structures that serve various functions in growth, survival, behavior, and reproduction. (Boundary: Stress at this grade level is on understanding the macroscale systems and their function, not microscopic processes.)  

By the end of grade 8. All living things are made up of cells, which is the smallest unit that can be said to be alive. An organism may consist of one single cell (unicellular) or many different numbers and types of cells (multicellular). Unicellular organisms (microorganisms), like multicellular organisms, need food, water, a way to dispose of waste, and an environment in which they can live.  

Within cells, special structures are responsible for particular functions, and the cell membrane forms the boundary that controls what enters and leaves the cell. In multicellular organisms, the body is a system of multiple interacting subsystems. These subsystems are groups of cells that work together to form tissues or organs that are specialized for particular body functions. (Boundary: At this grade level, only a few major cell structures should be introduced.)  

By the end of grade 12. Systems of specialized cells within organisms help them perform the essential functions of life, which involve chemical reactions that take place between different types of molecules, such as water, proteins, carbohydrates, lipids, and nucleic acids. All cells contain genetic information in the form of DNA molecules. Genes are regions in the DNA that contain the instructions that code for the formation of proteins, which carry out most of the work of cells.  

Multicellular organisms have a hierarchical structural organization, in which any one system is made up of numerous parts and is itself a component of the next level. Feedback mechanisms maintain a living system’s internal conditions within certain limits and mediate behaviors, allowing it to remain alive and functional even as external conditions change within some range. Outside that range (e.g., at a too high or too low external temperature, with too little food or water available), the organism cannot survive. Feedback mechanisms can encourage (through positive feedback) or discourage (negative feedback) what is going on inside the living system.

A central feature of life is that organisms grow, reproduce, and die. They have characteristic structures (anatomy and morphology), functions (molecular-scale processes to organism-level physiology), and behaviors (neurobiology and, for some animal species, psychology). Organisms and their parts are made of cells, which are the structural units of life and which themselves have molecular substructures that support their functioning. Organisms range in composition from a single cell (unicellular microorganisms) to multi-cellular organisms, in which different groups of large numbers of cells work together to form systems of tissues and organs (e.g., circulatory, respiratory, nervous, musculoskeletal), that are specialized for particular functions.  

Special structures within cells are also responsible for specific cellular functions. The essential functions of a cell involve chemical reactions between many types of molecules, including water, proteins, carbohydrates, lipids, and nucleic acids. All cells contain genetic information, in the form of DNA. Genes are specific regions within the extremely large DNA molecules that form the chromosomes. Genes contain the instructions that code for the formation of molecules called proteins, which carry out most of the work of cells to perform the essential functions of life. That is, proteins provide structural components, serve as signaling devices, regulate cell activities, and determine the performance of cells through their enzymatic actions.

Scientists can determine the exact age of a fossil by a technique called  Radiometric dating. Radiocarbon dating involves the determination of how much carbon is left in the fossil.

In radiocarbon dating, it is possible to determine how much carbon is left in the fossil, by looking at its half-life period.

Radiocarbon dating (also known as carbon dating) refers to the technique aimed at determining the age of a fossil by exploring the properties of a radioactive carbon isotope called radiocarbon.

Radiocarbon or carbon-14 (14C) is a radioactive carbon isotope of carbon that contains 6 protons and 8 neutrons, whose amount in a sample can de be used to determine the age of a given organic material.

Answers

Answer:

No, the offspring of two black sheep cannot have white wool. Since the black wool allele is recessive, both parents have to be recessive (ww) and so do not carry the dominant white wool allele. The only allele the parents can pass to their offspring is the black allele.

4. How does the life of a sperm cell vary among the mosses, ferns, gymnosperms and angiosperms?

Answers

Answer:

They evolved on land to begin with from earlier now extinct groups groups so there was no need to adapt to life on land, other than to adapt to different terrestrial environmental pressures. Land can be everything from next to a river to a hot desert to rocks to Antarctica, and plants grow in all those places.

As well, there are thousands of species that are floating aquatics or submerged aquatics, including many ferns, and even some gymnosperms grow as marginals, and many species of angiosperms, mosses, ferns, and even some gmnosperms grow as epiphytes, or as parasites, or other ways.

How does the air pressure at sea level compare with air pressure at higher elevations such as
Mt. Everest. In your explanation include information about the number of air molecules in a
parcel of air at that altitude and the affect of gravity on pressure at both altitudes.

Answers

Answer:

Pressure with Height: pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels.In addition, gravity is weaker at the equator due to centrifugal forces produced by the planet's rotation. It's also weaker at higher altitudes, further from Earth's centre, such as at the summit of Mount Everest

What is the most valid conclusion regarding ocean depth temperature, based on the data? The temperature and salinity increase with increasing depth. The salinity increases as the depth goes closer to zero. The bottom of the ocean is frozen and salinity levels are low. The ocean temperature never rises above 10°C and salinity remains constant.

Answers

The most valid conclusion concerning ocean depth temperature is B. The salinity increases as the depth go closer to zero.

 

Effect of Salinity on Water Depth

Decreasing ocean temperature increases ocean salinity. These occurrences put pressure on water as the water depth increases with decreasing temperature and increased salinity.

 

What is Ocean Salinity?

Ocean Salinity refers to the saltiness or amount of salt dissolved in a body of water. The salt dissolution comes from runoff from land rocks and openings in the seafloor, caused by the slightly acidic nature of rainwater.
