In what direction does blood flow through the heart?.
Answer:
The right ventricle pumps the oxygen-poor blood to the lungs through the pulmonary valve.
Explanation:
The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle through the mitral valve. The left ventricle pumps the oxygen-rich blood through the aortic valve out to the rest of the body.
Most of the atp production during cellular respiration occurs __________.
Answer:
Cellular respiration takes place in both the cytosol and mitochondria of cells.
Explanation:
The energy produced by the mitochondria is stored as potential energy in molecules called adenosine triphosphate (ATP). The main chemical produced in cellular respiration is ATP.
In snapdragon flowers, the allele for flower color shows incomplete
dominance. Flowers can be red (RR), white (WW), or pink (RW).
4. Two pink flowers are crossed how many offspring (%) are:
Red? % red?
White? % white?
Pink ?. % pink?
Answer:To get the most pink flowers, a red and white rose plant must be mated. Red would have two red alleles--RR and white would have two white alleles--WW. In this cross, all of the offspring would inherit one red allele and one white allele-RW and would be 100 percent pink!
Explanation:

In stratified epithelium, the cells in the deepest layer are often a different shape than the cells in the most superficial layer. This tissue is classified according to the shape of the cells in the ______ layer
Stratified epithelium is classified according to the shape of the cells in the apical layer, that is the layer towards the surface.
How is the stratified epithelial tissue classified?Stratified epithelium refers to the tissue that consists of two or more layers of epithelial cells. The main purpose of this multilayer is to protect the underlying tissues. These are present in areas that are more prone to wear and tear.
Stratified epithelium is classified on the basis of type of cell at the apical layer and underneath layers of cells can be varying. The types of stratified epithelium are as follows:
1. Stratified squamous epithelium - the cells at the apical layer are squamous, that is flat-shaped. Involved mainly in protection.
2. Stratified cuboidal epithelium - the cells at the apical layer are like cubes or hexagons. Involved in secretion and absorption as well as protection.
3. Stratified columnar epithelium - the cells at the apical layer are tall like columns and have cilia or villi, specialized for secretion and absorption.
4. Transitional epithelium - these apical layer cells are able to change shape to cuboidal or columnar, located in structures that are capable of expanding and contracting.
Thus, the correct answer is apical layer.

A physician takes a biopsy, or tissue sample, from the skin of a patient. Which observation of the cells in the tissue would most strongly support the conclusion that the patient has skin cancer? A. Many cells in the tissue sample appear identical to one another. B. All of the cells are packed closely together. C. Some of the cells were dead when the biopsy was obtained. D. A group of cells appear larger and rounder than surrounding cells.
The study of cells is called cell biology. There are two types of the cell on the basis of their number and these are unicellular and multicellular.
The correct answer to the question is option B that is All of the cells are packed closely together.
What is a biopsy?A biopsy is a medical test commonly performed by a surgeon, interventional radiologist, or interventional cardiologist. The process involves the extraction of sample cells or tissues for examination to determine the presence or extent of a disease.According to the question, the cancer cell is defined as the cell which loses its dividing property and divides unconditionally in a specific position from a clumped and called cancer cell.
Cell regulates its division with the contact of other cells and this property is known as contact inhibition.
Hence, The correct answer to the question is option B.

Which factor produced most of the oxygen that is found in the atmosphere today?.
The layer of the gases that surrounds the planet and is found in the layers of the planet held by gravity is called the atmosphere. It comprises many gases in certain ratios and varies in temperature according to altitude.
Living organisms produce most of the oxygen that is found in the atmosphere.
How a living organism plays role in oxygen production?Oxygen is the most essential and crucial gas required for the survival of the organism and the process that occurs. Living organisms like plants and trees are the major source for oxygen production and yield them by the process of photosynthesis. They utilize atmospheric inorganic resources like water, carbon dioxide and sun energy to create glucose(food molecule) and oxygen.Even small microscopic organisms like cyanobacteria use inorganic components and synthesize oxygen. Thus, phytoplankton and microorganisms also contribute to oxygen production.Therefore, living organisms yields most of the oxygen.
