Answer:
1. False
2. False
3. The adult stage for one-celled organisms is usually extremely long.
Explanation:
1. Yeast is a fungus that uses heterotrophic means of obtaining food. A yeast cell does not have the ability to perform photosynthesis (provide energy source) because it cannot make use of light energy from the sun. Hence, the answer is FALSE.
2. The cells of a yeast lacks chlorophyll pigment needed for the capturing of light energy. Hence, this statement is FALSE.
3. Yeast is a unicellular organism that reproduces via spores and budding. Budding is the asexual form of reproduction while they produce spores when stressed. However, the adult stage for one-celled organisms is usually extremely long.

Answer:the third one
Explanation:
Joanna read that certain perfumes would cause bees to leave the hive and act in an agitated fashion. She decided to investigate the response of bees to five different perfumes- Ralph Lauren, Armani, Mark Jacobs, Vera Wang, and the last is an odorless liquid. She placed a saucer containing 20ml of perfume A 10 meters from a beehive. She then recorded the total number of bees that emerged from the hive during a 15 minute interval and made observations on their behavior. Using a 30 minute interval between tests to allow recovery time for the bees, she then repeated the procedure to test the remaining three samples. Each test was conducted on the same day with similar weather conditions. whats the independent variable
Answer:
PERFUME
Explanation:
In an experiment, the independent variable is the variable that is changed or manipulated by the experimenter in order to effect a measurable response in the dependent variable.
In this experiment, Johanna is trying to investigate the response of bees to five different perfumes- Ralph Lauren, Armani, Mark Jacobs, Vera Wang, and an odorless liquid, which is the control. Hence, the PERFUME is the independent variable because it is the manipulated variable.
can someone give me 4 similarities between mitosis and meiosis
Answer:
Both mitosis and meiosis are multistage processes. The stages are interphase, prophase, metaphase, anaphase and telophase. The same general processes occur in each of these stages for mitosis and meiosis. Interphase is cell growth and DNA replication in preparation for cell division.
Explanation:
Answer:
The answer is listed below...
Explanation:
Mitosis and Meiosis are two completely different terms but could be alike in a way. Both Mitosis and Meiosis are involved in the duplication of a cell's DNA content. A common goal of mitosis and meiosis is to split the nucleus and its DNA content between two daughter cells, although the meiosis stage is longer. Each strand of a chromosome is replicated, resulting in two sister chromatids for each chromosome. Both mitosis and meiosis produce fresh new cells based on their parent cells' genes.
Need some differences?
Mitosis is the method by which cells split in half to produce two new cells, identical to the parent cell. Meiosis is a special type of cell division that applies only to sex cells. Mitosis produces two cells from one parent using one division event. But meiosis produces four new child cells with two divisions, each of which has half the genetic material of its parent.

i have to write an Ocean Observation Method Paragraph can some one help me please?
Answer:
Changes in marine biodiversity—the variety and variability of life in the ocean—can be an early indicator of change, provided it's noticed. The U.S. Marine Biodiversity Observation Network (MBON) aims to ensure that scientists not only notice changes in biodiversity at locations around the nation, but also have the tools in place to better understand what these changes tell us about ocean health over time. But marine life doesn't know borders. That's why the U.S. network also supports international cooperation with other marine biodiversity networks, research institutions, governmental and non-governmental organizations and stakeholders around the world towards development of a truly

A molecule has been isolated from a cell. The molecule's structure has a three dimensional shape and is made of folded chains of amino acids. The function of this molecule is enzymatic catalysis of glycolysis. An analysis of this molecule would show that it contains which of these elements that would NOT be found in carbohydrates? A) carbon B) nitrogen C) oxygen D) phosphorus E) sulfur
Answer:
B) nitrogen
Explanation:
According to this question, a molecule which has been isolated from a cell has a three dimensional shape made of folded chains of amino acids. The molecule functions in the enzymatic catalysis of glycolysis. Based on the description of this molecule, it can be determined that it is a PROTEIN.
This is because PROTEINS are the biomolecules that are composed of amino acids monomers. The three dimensional shape of the molecule represents the protein at the TERTIARY LEVEL. However, in the structure of the amino acids, which forms the protein molecule, a central carbon is attached to a carboxyl group (-COOH), an anime group (-NH2) and a R side chain.
The protein molecule, therefore, contains NITROGEN element, which cannot be found in carbohydrates (made up of only carbon, hydrogen and oxygen).
An analysis of this molecule (protein) would show that it contains this chemical element that would not be found in carbohydrates: B) nitrogen.
A molecule with a three (3) dimensional shape and comprises folded chains of amino acids describes a protein.
Also, one of the function of protein is the enzymatic catalysis of glycolysis.
Generally, protein is a macromolecule which is formed as a result of the union of many folded chains of amino acids.
The molecular structure of protein is made up of the following:
A carboxyl group (COOH).An anime group (NH2).A R-side chain.In conclusion, an analysis of protein would show that it contains nitrogen which would not be found in carbohydrates.

What is the relationship between air pressure and wind?
Answer:
Wind is air pressure converted into movement of air. When air slows down, its pressure increases. The kinetic energy or momentum of a moving air mass is converted in static atmospheric pressure as the air mass slows down. This means that higher wind speeds will show lower air pressure readings.
Answer: As the Sun unevenly heats the surface of the Earth, air rises and sinks, resulting in high and low regions of air pressure. As air rises, the pressure lowers and surrounding air moves in to replace it, causing wind. The more the pressure changes over a given distance, usually the faster the wind will be.
