Explanation:
Animal cells are considered eukaryotic, and bacteria cells are considered prokaryotic. The difference between these two cell types is that–
Answer:
The main difference is that in prokaryotic cells the genetic material is not separated from the cytoplasm and eukaryotes present the genetic material is organized in chromosomes surrounded by a membrane that separates them from the cytoplasm.
Explanation:
All living beings are made up of cells that, depending on their structure, can be eukaryotic or prokaryotic. The eukaryotic cell is the building block of life for protozoa, fungi, plants, and animals. It is characterized by keeping its genetic material packed within a membrane, forming the nucleus. It also has other intracellular structures surrounded by membranes, known as organelles: mitochondria, vesicles, chloroplasts, among others.The prokaryotic cell is a simple organism composed of a membrane and cytoplasm, which lacks a nucleus and does not present organelles like eukaryotic cells ( mitochondria, chloroplasts and endoplasmic reticulum). In addition, it has a cell wall that supports the cell.

Explanation:
What might explain why light travels in a straight line? Group of answer choices If there is nothing to interfere with light waves, they should travel in a straight line. Light waves will always travel in a straight line, even if they come into contact with another object. Light waves don't travel in a straight line. Light waves travel in a straight line because sound waves travel in a straight line.
Answer:
A. If there is nothing to interfere with light waves, they should travel in a straight line.
Explanation:
A light wave is a transverse wave, and do not require material medium for its propagation. It travels in straight lines in all directions from the source.
Light waves travel in straight paths (a principle referred to as the rectilinear propagation of light) known as rays, of which the combination of two or more rays gives a beam of light. When there is an obstruction on or interference with the path of light, it stops traveling in a straight line due to either absorption, refraction or diffraction.
When light from a source is forced to travel in one direction only, it is said to be polarized.

Which of the following methods uses the decay of atomic particles in an object to find its exact age? (3 points)
a
Fossil dating
b
Geologic dating
c
Radioactive dating
d
Relative dating
Answer:
C. Radioactive dating
I know this because radioactive dating is done by examining the atomic particles found in an object. The atomic particles decay over time at a predictable rate. Scientists are able to measure the rate of decay to establish the age of the fossil, organism, and/or material.

Max tried an experiment in which he added red-dyed salt water to clear freshwater. He noticed that a lot of the red water sank below the clear water. Which of the following statements explains why this happened?
a. Adding salt to water makes it more dense.
b. Adding salt to water makes it less dense.
c. Adding salt to water decreases its temperature.
d. Adding salt to water increases its temperature
Answer:
A
Explanation:
Adding salt to water causes its density to increase. Denser water will sink below less dense water.
As salt water is denser and will sink at the bottom and adding the salt raises the temperature of water body and hence will make it more warm and saline.
A max tries to add red dyed salt water to clear the fresh water he sees a red color sinking below the fresh water that is cool.The option D is correct.

Several kinds of specialized cells work together to create the sense of hearing. Hair-shaped cells sense vibrations and nerve cells send signals to the brain. Structural cells hold the hair cells in place. No matter their specialty, which functions must all cells perform to survive? Choose the three statements that apply.
Answer:
The correct answer is -
bringing in nutrients and water,
getting rid of wastes, and
obtaining energy.
Explanation:
All cells no matter what type of cell they are or their specialty, they need to bring water and nutrients to work properly and survive. These cells also need to remove cellular waste to prevent toxicity in the cell. All the toxic material or metabolic waste must be removed from the cells.
All the cells of the bodu=y including hair-shaped cells or structural cells all required energy to perform their function therefore obtaining energy is one of essential function cell need to be performed.

Parents that are heterozygous for having freckles (dominant) are crossed. Which correctly describes their offspring?
O Twenty-five percent have freckles.
O Twenty-five percent are Ff.
O Seventy-five percent have freckles.
O Seventy-five percent are Ff.
Answer:
In a cross of parents heterozygous for having freckles, the ratio of their offspring is (C) Seventy-five percent have freckles. Let allele F be dominant and allele f be recessive. Heterozygous parents will have genotype Ff.
Explanation:
Seventy-five percent have freckles.
What is homozygous dominant genotypes?Homozygous dominant is a genotype that consists of two dominant alleles for a gene.
What is heterozygous dominant in biology?'heterozygous' organism for a particular trait means that it possesses dissimilar alleles (e.g. Aa); one of the alleles is dominant and the other is recessive.
Hence, C is correct option

(REPOST)if something needed to enter the cell and couldn't go through the phospholipid bilayer, how else could it enter the cell?
Answer:
by being facilitated
Explanation:
If something needs to enter the cell and could not go through the phospholipid bilayer, it could be assisted through a process known as facilitated diffusion.
Facilitated diffusion involves the passive movement of molecules that will ordinarily not pass through the phospholipid bilayer of the cell membrane through the help of the channel or carrier proteins.
If the phospholipid bilayer will not allow some molecules to pass through it as a result of a concentration gradient, the channel/carrier proteins form a special passage and the molecule is facilitated by such passage to move across the membrane.
