Answer:
Rutherford described the atom as consisting of a tiny positive mass surrounded by a cloud of negative electrons. Bohr thought that electrons orbited the nucleus in quantised orbits.
Explanation:
Bohr built upon Rutherford's model of the atom. In Rutherford's model most of the atom's mass is concentrated into the centre (what we now call the nucleus) and electrons surround the positive mass in something like a cloud.
Bohr's most significant contribution was the quantisation of the model. He believed that electrons moved around the nucleus in circular orbits with quantised potential and kinetic energies. So it was not possible for electrons to occupy just any energy level.

Answer:
All cells share common traits that help scientists draw conclusions about the basic needs and functions of living organisms.
Answer: The human and the animal brain form a part of the central nervous system. The brain of both are made up of neurons and neuroglia. Its main function is to control thoughts and body movement. The brain of all the vertebrate animals is divided into forebrain, midbrain, cerebellum, hind brain, medulla oblongata and pons.

Answer:
carboxyhemoglobin
Explanation:
When Carbon monoxide reacts with haemoglobin in the blood, it forms carboxyhemoglobin which prevents the normal flow of oxygen and then it damages the central nervous system and also causes anoxia which could lead to death
You place different colored liquids in a hummingbird feeder and count how many hummingbirds visit.
What is the manipulated variable and the responding variable?
Answer:
the different colored liquids would've the manipulated while the amount of hummingbirds that visit is the responding variable.
When you place different colored liquids in a hummingbird feeder and count how many hummingbirds visit than the manipulated variable is the colored liquids that you place in the hummingbird feeder and responding variable is the number of hummingbirds that visit the feeder.
Manipulated variable is the colored liquids that you're placing in the hummingbird feeder. You might use liquids of different colors such as red, yellow, blue, or green. Each color represents a different treatment condition.
Responding variable is the number of hummingbirds that visit the feeder. You're counting how many hummingbirds are attracted to the feeder under each treatment condition (different colored liquids).
Based on the results of your experiment that if you find that hummingbirds are indeed more attracted to certain colors, your experiment would provide valuable insights into how visual cues, such as color, impact their foraging behavior.

What is a geomagnetic field and how do the forces work on Earth?
All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other. When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field.

Mitosis
DEFINITION:
Meiosis
DEFINITION:
Answer:
Mitosis a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.
Explanation:
Meiosis a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores.
Answer :
Mitosis : Mitosis is a process of asexual reproduction observed in unicellular organisms.
Meiosis : Meiosis is the process in which a single cell divides twice to form four haploid daughter cells. These cells are the gametes – sperms in males and egg in females.

Answer:
Amino Acids
Explanation:
Because we don't store amino acids, our bodies make them in two different ways: either from scratch or by modifying others. Nine amino acids—histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine—known as the essential amino acids, must come from food.

in which cellular structure are the enzymes of the calvin cycle localized?
The Calvin cycle is the photosynthetic cycle that is also called the C3 cycle, where the carbon is fixed. The enzymes of the Calvin cycle are localized in the stroma of the chloroplast.
What is the Calvin cycle?The Calvin cycle is the chemical reaction that occurs in plants and is a part of photosynthetic reactions where fixation, reduction, and regeneration of carbon compounds take place. The cycle takes place in the chloroplast of the plant cell.
The cycle and the enzymes are located in the stroma of the chloroplast where the two molecules of the product, glyceraldehyde-3-phosphate are released. The stroma is an internal space characterized by colorless fluid.
They include the ribosomes, chloroplast DNA, enzymes, starch, etc., that are needed by the cell to perform certain activities. Here, the enzymes are used for light-independent reactions.
Therefore, the stroma of the chloroplast is the site of the Calvin cycle.

Using your own words explain how the process of
Photosynthesis occurs (hint - what must go in and
what is created?)
Answer:
hope this will help you
Explanation:
photosynthesis is the process in which plant make their own food with the help of sunlight,water and carbon dioxide. water and carbon dioxide are raw materials in photosynthesis because they help to prepare their food.During photosynthesis, plants take in carbon dioxide and water from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.so sunlight water and carbon dioxide should go in which create oxygen.
