Visible light specturm ranges between infrared rays and ultraviolet rays

Answers

Answer 1

Answer: True. Any color of light is nothing but an electromagnetic wave that enables us to see things around us. Humans mostly can see wavelengths between the Electromagnetic spectrum and the Ultra violet region. The wavelength of green light is longer by a small margin than the wavelength of the blue light. Red light has the highest wavelength among all the available colors of light.

Endocrine disruptors are best described as _______.a. highly toxic pesticides
b. hormone mimics
c. plastics precursors
d. industrial byproducts

Answers

Answer:

Endocrine disruptors are the synthetic or natural chemicals that may interfere with the functioning of the endocrine system in the human body. These chemicals mimic the naturally occurring hormones produced in the body like estrogen (a female sex hormone) and androgen (a male sex hormone) also these interfere with the production of the thyroid hormone. They bind to the receptors present in a cell and prevents the endogenous hormone from binding. The normal signaling process fails to respond properly.

Chemicals that functions as endocrine disruptors include dioxine, polychlorinated biphenyls (PCBs), pesticides and DDT.

Answer:

the answer to that one is D

Answer:

It might be A

Explanation:

It might be A because stem cells are usually found in brain, blood, bone marrow, muscle, skin, heart, and liver tissues.

Why is diffusion and osmosis important to the cell

Answers

uses energy to move substances against (up) a concentration gradient or across a partially permeable membrane. In active transport a special transport protein in the cell membrane picks up the useful particle on one side of the membrane. The transport protein then rotates through the membrane and releases the particle on the other side of the membrane. This uses energy from cellular respiration.

Ron is observing an onion cell on a slide under a microscope. He sees chromatids being pulled to opposite ends of the cell. Which phase is he seeing?

Answers

The answer is anaphase.

Ron is obviously observing cell division - mitosis. Mitosis consists of four phases - prophase, metaphase, anaphase, telophase and cytokinesis.

1. Prophase: Chromatin in the nucleus condenses and chromosomes pair up

2. Metaphase: Chromosomes line up at the center of the cell. The sister chromatids are joined together.

3. Anaphase: The sister chromatids separate from each other to the opposite sides of the cells.

4. Telophase and Cytokinesis: Membrane forms around each set of chromosomes on two opposite sides of the cells and cell divides into two identical daughter cells.

Therefore, sister chromatids being are pulled to the opposite ends of the cell in anaphase.
