This indicator is an estimate of the amount of space on the earth that an individual uses in order to survive using existing technology. This space includes the biologically productive land and water area that produces the resources consumed by that individual such as food, water, energy, clothing, and building materials. It also includes the amount of land and water required to assimilate the wastes generated by that person. In other words, the ecological footprint measures a person's demand on the bio-capacity of the Earth.
Answer: The answer is that the phenotypic ratio among phenotypes produced from an F1 X F1 dihybrid cross is 9:3:3:1.
Explanation:
Independent assortment of genes explains how alleles on different chromosomes arrange independently of one another during gamete formation.
So, a dihybrid cross involving TWO characters (e.g Seed color & seed shape) would have its respective alleles DISTRIBUTED whether dominant or recessive, for crossing to occur and yield varying proportion of offspring in the well spread ratio of 9:3:3:1; making it a consequence of independent assortment of genes
<span>Levels of OrganizationIn unicellular (single-celled) organisms,
the single cell performs all life functions. It functions independently.
However, multicellular (many celled) organisms have various levels of
organization within them. Individual cells may perform specific
functions and also work together for the good of the entire organism.
The cells become dependent on one another.Multicellular organisms have
the following 5 levels of organization ranging from simplest to most
complex:<span><span>LEVEL 1 - Cells<span><span>Are the basic unit of structure and function in living things.
</span>May serve a specific function within the organismExamples- blood cells, nerve cells, bone cells, etc.</span></span><span>LEVEL 2 - Tissues<span>Made up of cells that are similar in structure and function and which work together to perform a specific activity
Examples - blood, nervous, bone, etc. Humans have 4 basic tissues: connective, epithelial, muscle, and nerve.</span></span><span>LEVEL 3 - OrgansMade up of tissues that work together to perform a specific activityExamples - heart, brain, skin, etc.</span><span>LEVEL4 - Organ Systems
<span>Groups of two or more tissues that work together to perform a specific function for the organism.
Examples - circulatory system, nervous system, skeletal system, etc.
The
Human body has 11 organ systems - circulatory, digestive, endocrine,
excretory (urinary), immune(lymphatic), integumentary, muscular,
nervous, reproductive, respiratory, and skeletal.</span></span><span>
LEVEL 5 - Organisms
<span>
Entire
living things that can carry out all basic life processes. Meaning they
can take in materials, release energy from food, release wastes, grow,
respond to the environment, and reproduce.
<span>Usually made up of organ systems, but an organism may be made up of only one cell such as bacteria or protist.
</span>Examples - bacteria, amoeba, mushroom, sunflower, human</span></span></span></span>
Answer:
This is the remaining incomplete part of the question.
Requires separation of template strand Uses helicase Occurs during interphase of cell cycle Require primers Occurs in nucleus Requires dNTPs Produces Okazaki fragments Requires DNA polymerase Requires Primase Requires Taq DNA polymerase Requires cycles of heating Occurs in cytoplasm Occurs during anaphase of mitosis
Explanation:
Cellular DNA replication Polymerase chain reaction
Requires separation of template Requires separation of template
strand strand
Requires dNTPs Requires dNTPs
Uses helicase Requires cycles of heating
Requires Primase Require primers
Requires DNA polymerase Requires Taq DNA polymerase
Occurs during interphase of cell cycle
Occurs in nucleus Occurs in test tube
Produces Okazaki fragments
Answer:
In the particular case, acute coronary syndrome (ACS) have occurred in the cardiac arrest. The ACS refers to a condition that arise due to the decrease of blood flow in the coronary arteries, such that the segment of the heart muscle is not able to function properly or dies. Some of the signs and symptoms of ACS are chest pain and discomfort, pain rising in your chest and in the arms, shoulders, neck, or jaw, indigestion, nausea or vomiting, shortness of breath, unusual fatigue, excessive sweating, restlessness, dizziness, or fainting.
