Which of the four factors that affect evolution apply to the finches that the Grants studied? Use evidence from your research to support your answer.
Answer:
The four factors that affect evolution are mutations, natural selection, genetic drift and the gene flow, In the case, if the ground finches that Grants studied, we can observe the working of the natural selection. Due to change in the conditions in the environment, the large beak was an advantageous trait that was favored by the natural selection. The result of this process was an increase in numbers of large beaked finches and decrease in small-beaked finches compared to the initial numbers in the population.
Explanation:
Factors that affect evolution.
As per the question the evolution is a gradual process that includes the changes in the body of the organisms thereby making them more stronger and dynamic than others. The 4 features that affect evolution are mutations, natural selection, genetic drift, and gene flow.
The answer is thus are a major factor that leads to evolution in specie.
As per the case, Grants studied his works of natural selection. As per the changes associated with the environment, the large beak was an advantageous trait that was favored by natural selection. This leads to the increase in the size of the finches and the decline of other properties. Such a beak size, color, and even behavior. Hence the four-factor to consider are genetic drift, natural selection, adaptation and mutation (evolution).Learn more about the four factors.

Which of the following is the best example of a way human lifestyles affect environmental systems?
Using radioactive materials causes ground pollution as it causes methane to seep into the ground.
Burning fossil fuels causes water pollution by increasing the amount of water vapor in the atmosphere.
Deforestation causes acid rain by decreasing carbon dioxide (CO2) in the atmosphere.
Using aerosols that contain chlorofluorocarbons (CFCs) decreases the amount of protective ozone (O3).
Answer:
Burning fossil fuels causes water pollution by increasing the amount of water vapor in the atmosphere.
Explanation:
This is the best example because when burning fossil fuels, greenhouse gases are released, which can cause global warming. This affects the environment.

after water, which are the next most abundant substances in the human body?
Answer:
Proteins
Explanation:
After water, Proteins are the next most abundant substances in the human body.
In adult men , 60% of body is comprised of water whereas in women , 55% of body is comprised of water.
Protein makes up around 20% in body and is present in every cell.
What are Proteins?Proteins are large complex molecules and play critical roles in the body. They do most of the work in their cells and required for structure functions and regulation of body tissues.
Proteins are made up of smaller units called amino acids, which are attached to one another in long chains.
There are 20 different types of amino acids that can be combined to make a protein.
The sequence of amino acids determines about each protein’s unique 3-dimensional structure and its specific function.
Amino acids are coded by combinations of three DNA building blocks (nucleotides), determined by the sequence of genes.
Functions of Proteins:
1. As an Antibody- Bind to specific foreign particles such as bacteria and virus to help protect the body.
2. As an Enzyme- Carry out thousands of chemical reactions taking place inside the cell
3. As a Messenger- Transmit signals to coordinate biological processes between different cells, tissues and organs.
4. As a Structural Component- Providing structure and support to cells.
5. Transport/Storage- Binding and carrying atoms and small molecules within cells and throughout the body.

Water is extremely important to the survival of all organisms found on Earth.
Water helps support life in many ways. These life providing properties of water
are all basically derived from water's ability to form Hydrogen bonds, as a result
of it being a polar molecule. Describe a typical Hydrogen bond between
Hydrogen and Oxygen.
Your answer
Answer:
Water is called the "universal solvent" because it is capable of dissolving more substances than any other liquid. This is important to every living thing on earth. It means that wherever water goes, either through the air, the ground, or through our bodies, it takes along valuable chemicals, minerals, and nutrients.
Explanation:
SO THE ANSWER IS (A): Water helps support life in many ways. These life providing properties of water.
how fast does a body decompose to skeletal remains?
Answer:
Timeline. In a temperate climate, it usually requires three weeks to several years for a body to completely decompose into a skeleton, depending on factors such as temperature, humidity, presence of insects, and submergence in a substrate such as water.
Explanation:
Which statement accurately describes the bond that forms between carbon and oxygen to create carbon dioxide
Answer:
It's a non-polar covalent bond.
Explanation:
Non-polar means they do not interact with water. Carbon dioxide and Oxygen bonded together by sharing electrons equally.

How are all living cells organized?
Answer:
TaxonomyExplanation:
The cell is the most basic unit of life. Similar cells together form tissues. Similar tissues together form organs. Organs work together in organ systems. Organ systems form complex organisms. Because living things are diverse, taxonomy was created to group organisms into categories and to understand their evolutionary relationships.

And have an amazing day <3
Answer:The biological levels of organization of living things arranged from the simplest to most complex are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.
Explanation:Cells are divided into several compartments, each with a characteristic structure, biochemical composition, and function.
These compartments are called organelles. They are delimited by membranes composed of phospholipid bilayers and a number of proteins specialized for each type of organelle.
All eukaryotic cells have a nucleus surrounded by a nuclear envelope, and a plasma membrane that borders the whole cell.
Most eukaryotic cells also have endoplasmic reticulum, a Golgi apparatus, lysosomes, mitochondria, and peroxisomes.

Which of the following is not a lipid?
Asteroid
B cholesterol
C
wax
D cellulose
Answer:
cellulose
Explanation:
lipids are fats oils or waxes. cellulose is a fiber
Answer:
cellulose
Explanation:
Examples of lipids include fats, oils, waxes, certain vitamins (such as A, D, E and K), hormones and most of the cell membrane that is not made up of protein. Therefore waxes are not the answer.
Steroids are lipids because they are hydrophobic and insoluble in water, but they do not resemble lipids since they have a structure composed of four fused rings. Cholesterol is the most common steroid and is the precursor to vitamin D, testosterone, estrogen, progesterone, aldosterone, cortisol, and bile salts. Therefore steroid and cholesterol is not the answer.
