What type of particles move to create electricity?
Answer:
the particles are called electrons
Answer:
electrons is what thay are cald :) :)
Explanation:
Which type of energy is the flow of electrons from a negative to a positive?
AC is the kind of electrical flow we get from a typical electrical outlet in a home. AC is when the electrons flow in two directions, from the positive to the negative terminal and from the negative to the positive terminal, 'alternating' between the two directions.
Which of the following statements describes a way in which bacteria differ from animals and plants?
The BEST statement that describes how bacteria differ from animals and plants is bacteria do not have membrane-bound organelles and nuclei.
Prokaryotic cells (i.e. bacteria and Archea) have no nuclei and lack organelles.In these cells (prokaryotic cells), the genetic material consists of a single circular chromosome localized in a region of the cytoplasm called the nucleoid.On the other hand, eukaryotic cells (e.g., plant cells and animal cells) have their genetic material delimited by a membrane-bound organelle known as the cell nucleus. Moreover, eukaryotic cells also have different types of membrane-bound organelles that carry out specialized functions in the cell (e.g., mitochondria, chloroplasts, Golgi apparatus, vacuoles, etc).In conclusion, the BEST statement that describes how bacteria differ from animals and plants is bacteria do not have membrane-bound organelles and nuclei.

Humans are typically fueled by aerobic respiration. In which scenario might anaerobic respiration begin instead?
O after eating a high fat meal
O after sitting at a desk for 3 hours
O after running 20 miles
O after walking across a basketball court
Answer:
C. After running 20 miles
Explanation:
Anaerobic respiration only occurs when an organism lacks all the oxygen we need to function. After running 20 miles, you will be out of breath, and you will have been using more energy than your respiratory system could produce alone. Due to this, your body will start using some of your energy stored within cells in order to continue functioning. This kind of respiration is basically 'burning calories'.
2. Messages move to and from the brain along thin cells called?
Answer:
Messages to and from the brain travel along the nerves, which are strings of long, thin cells called neurons.
Explanation:
Answer: Messages to and from the brain travel along the nerves, which are strings of long, thin cells called neurons (see Figure 6.2). Chemical- electrical signals travel down the neurons much as flame travels along a firecracker fuse. ... Dendrites receive impulses, or messages, from other neurons and send them to the cell body.

Monosaccharides are the monomer of which organic
compound?
Monosaccharides are the monomer of organic compounds called polysaccharides (carbohydrate).
WHAT ARE MONOSACCHARIDES:
Monosaccharides are simple compounds that contain one unit of sugar (saccharide). They are monomeric units of larger organic compounds called POLYSACCHARIDES, which are complex carbohydrates. Monosaccharides cannot be further broken down as they are the simplest form of carbohydrate molecules. Examples of monosaccharides, also called simple sugars are glucose, fructose, galactose etc. and they are monomers of polysaccharide molecules like starch, cellulose etc.Hence, monosaccharides are the monomer of organic compounds called polysaccharides (carbohydrate).

Genetic variation in the population allowed some weeds to survive.
The spray caused some individuals to mutate, and they were able to survive and
reproduce.
Answer:
Genetic variation in the population allowed some weeds to survive

Answer: Two parents, one with type B blood and one with type A blood.
Explanation: They both have different blood types, so that leads to the child having an O blood type.
Hope this helps!!
Sorry if it's wrong!!
Have a great day!!
If the two parents have blood group A and blood group B with their child of type O blood. Then, the possible genotypes of the parents is AO and BO. Thus, the correct option is A.
What is Blood group?A blood type is the classification of blood. Classification of blood group is based on the presence and absence of antibodies and inherited antigenic substances on the surface of red blood cells. These antigens are biomolecules which may be proteins, carbohydrates, glycoproteins, or glycolipids, depending on the blood group system.
There are four main blood groups which are A, B, AB and O. Blood group is determined by the genes a person inherit from the parents. In a cross between one parent with blood type A and one with blood type B having child with blood type O has genotypes AO and BO. The genotype is shown in the punnett square.
Therefore, the correct option is A.

I will mark brainliest!! THANK YOU! Students are discussing differentiation of cells in an organism. Which student has to most accurate description of differentiation?
Answer:
Student 2
Explanation:
I think it is student 2 because differentiation is the dividing and changing of embryonic stem cells into cells that are specialized in structure and function. Some stem cells form liver cells, some heart cells, muscle cells.
Answer: Student 1: differentiation occurs during reproduction.
Explanation:
The process of cell differentiation starts with the fertilization of the female egg. As soon as the egg is fertilized, cell multiplication is initiated resulting in the formation of a sphere of cells known as the blastocyst.

What must be true about the number of chromosomes in each sex cell (when compared to the number of chromosomes in body cells
Answer:
The number of chromosomes in sex cell must be haploid (1n) as compared to body cell which is diploid(2n).
Explanation:
Body cells are diploid while the sex cells are haploid. We can say that sex cells contain half number of chromosomes as compared to body cells.
The number of chromosomes in each s-ex cell is half the number chromosomes in body cells.
Chromosomes:Every cell in the human body contains 23 pairs of such chromosomes; our diploid number is therefore 46, our ‘haploid’ number 23. Of the 23 pairs, 22 are known as autosomes. The 23rd pair is made up of the s-ex- chromosomes, called the ‘X’ and ‘Y’ chromosome. These 46 chromosomes carry the g-enetic information that’s passed from parent to child through heredity.

C- All members of the population are genetically similar and are less likely to survive environmental change.
Explanation:
In asexual reproduction, there is no diversity since the offspring gets all their genes from their parent. That being said, they won't be able to inherit traits that would help them survive in a changing environment since there is no diversity of traits that would help them in other environments.
