Compare the advantages and disadvantages of demolishing an old building versus renovating it.
Answer:
Demolishing a building involves pulling down the whole structure and building from the scratch while renovation doesn’t involve pulling down the whole structure. It involves pulling down some parts of the building or simply modifying the building.
An advantage of Demolition is that the individual is able to build from the scratch which permits him/her to have the exact structure wanted.
A disadvantage of this is the high cost incurred on demolition and building from the scratch.
An advantage of Renovation is the less cost involved since it only requires some modifications and not total pulling down of the structure.
A disadvantage of Renovation is the inability to get the exact building taste the individual hoped for.

The plane of Earth's orbit around the Sun is called the: ?
Answer:
its called The Ecliptic.
Explanation:
The plane of Earth's orbit around the Sun is called the "ecliptic plane." The ecliptic plane is an imaginary flat plane that represents the average path traced by Earth as it orbits the Sun.
The Ecliptic plane serves as a reference plane for locating the positions of celestial objects in the sky, including the Sun, Moon, planets, and stars. The ecliptic plane is inclined at an angle of approximately 23.5 degrees with respect to Earth's equator, giving rise to the changing seasons as Earth orbits the Sun.
Therefore, the ecliptic plane represents the average path of Earth's orbit around the Sun and serves as a reference for understanding celestial positions and movements. Its tilt plays a vital role in determining Earth's seasons, and its alignment with other planets enables various astronomical phenomena.

what does your blood pick up from the cells
Answer:
Waste
Explanation:
The blood brings necessary things, like oxygen and nutrients to the cells. After the cells are given these things, the blood picks up waste products, such as carbon dioxide or excess water, and delivers it to certain areas to be removed from the body. For example, carbon dioxide is brought to the lungs by the blood, so it can be exhaled out.
All cells need energy to live. How do the organelles in the plant cell above work together to get and use this energy?
A.
The nucleus makes energy from materials in the cell, and the vacuole stores this energy until the cell needs to use it.
B.
Chloroplasts make food using energy from the Sun, and mitochondria break down this food to release energy for the cell.
C.
Mitochondria take in food from the environment, and the nucleus breaks down this food to release its energy to the cell.
D.
The vacuole takes in energy from the environment, and chloroplasts change this energy into a form the cell can use.
Answer:
B
Explanation:
Glucose and other carbohydrates made by plants during photosynthesis are broken down by the process of aerobic cellular respiration (requires oxygen) in the mitochondria of the cell. This releases energy (ATP) for the cell. Because they break chemical bonds of glucose to release energy to do work in a cell.
Chloroplasts make food using energy from the Sun, and mitochondria break down this food to release energy for the cell. Thus, the correct option is B.
How do the organelles work in a plant cell?
Plant cell organelles are the specialized organelles which help to maintain the structure of the plant cell, such as the water containing vacuoles and the rigid cell wall which is made up of cellulose. The chloroplasts in the plant cell are the organelles that contain chlorophyll pigment and allow plant cells to do photosynthesis and produce carbohydrate.
Glucose and other carbohydrates (sugars) are made by plant cells during photosynthesis are then broken down by the process of aerobic cellular respiration which requires oxygen molecule in the mitochondria of the plant cell. This releases energy in the form of ATP for the cell. Because they break the chemical bonds which are present in the glucose molecule to release energy to do work in a cell.
Therefore, the correct option is B.

A female rabbit can give birth to over 40 baby rabbits a year. Suppose all of her
offspring survived and reproduced, all of their offspring survived and
reproduced, and so on. If that happened, in only eight years the mass of rabbits
would exceed the mass of Earth! So, why aren't we overrun with rabbits? What
keeps the rabbit population in check?
Answer:
Predeators such as us and others that eat these rabbits keep their population in check. Also these rebbots that are being born will die soon also, menaing their popultaion is filling and taking away, then refilling again and again with them dying.Explanation:
The population of rabbits could have overrun human population ordinarily, but the presence of limiting factors would hinder it.
The limiting factors are biotic and abiotic environmental factors that prevents the population of organisms from getting to their biotic potential. In other words, limiting factors will not let the population of organisms grow perpetually. These factors include:
Competition for limited resourcesDiseasesNatural disastersPredationIn the real sense, the earth has the maximum number of individuals from each species it can support based on the resources it has, otherwise known as carrying capacity. Thus, the population of any species of living organism cannot grow without checks.

Which statement describes the ability of the cell membrane to allow various substance to move through it?
The cell membrane is selectively permeable.
The cell membrane is composed of lipids and phosphates.
The cell membrane is both hydrophilic and hydrophobic.
The cell membrane is a bilayer structure.
Answer:
the cell membrane is selectively permeable
Explanation:
hope that helped
The statement that is the cell membrane is selectively permeable is the statement, which describes the tendency of the cell membrane to permit various substances to move through it.
• The cell membrane comprises a phospholipid bilayer with proteins embedded in it. These proteins perform a number of functions, and the most important function it performs is that they regulate what moves out and what moves in the cell.
• The membrane is selectively permeable as the substances do not pass through it indiscriminately.
• Some of the molecules like oxygen and hydrocarbons can pass through it, while some of the large molecules like glucose and sugars cannot pass through it.
Thus, the cell membrane is selectively permeable.
