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

What are grana?
please help :)
Answer:
Please Mark as Brainliest. Please!!!!!!!
Explanation:
What are Grana?
We all need photosynthesis. All of us living on Earth's surface, that is. Turning light into food energy is the foundation of almost all food chains on Earth and is the livelihood of plants and algae. These organisms house chloroplasts within their cells, organelles responsible for manufacturing energy through the process of photosynthesis. It is within chloroplasts that we find many grana.
Grana (plural of 'granum') are stacks of structures called thylakoids, which are little disks of membrane on which the light-dependent reactions of photosynthesis take place. Stacked into grana, the shape of the thylakoids allow for optimum surface area, maximizing the amount of photosynthesis that can happen.
Within the chloroplast the grana resemble stacks of green pancakes, and are not uniform in their height or distribution. The grana are connected to each other by way of lamellae, or membrane that bridge the grana but also participate in the photosystem 1 stage of photosynthesis. All parts within the chloroplast are surrounded by a liquid suspension called stroma.

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.

One of the atmospheric layers was created by living things to help keep living things alive. What is that layer?
* exosphere
*tropopause
*ozone
*thermosphere
Answer: Troposphere
Explanation: The Troposphere: The Layer in Which We Live
The lowest layer of the atmosphere, which lies next to the
Earth’s surface, is called the troposphere. The troposphere is also
the densest atmospheric layer. It contains almost 90% of the
atmosphere’s total mass! Almost all of the Earth’s carbon dioxide, water vapor, clouds, air pollution, weather, and life-forms
are in the troposphere. As shown in Figure 4, temperatures vary
greatly in the troposphere. Differences in air temperature and
density cause gases in the troposphere to mix continuously.
Answer: That would be the ozone layer.
I took the test to double check the guy above me, and Ozone seemed to be the answer.

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.
