water makes up what percentage of our body weight?
Answer:
Water represents between half and two thirds of a person's average weight. Adipose tissue has a lower percentage of water than lean tissue, and women tend to have more fat, which is why the percentage of water in women is lower (52% to 55%) in relation to the average body weight of a male (60%).
Explanation:
Answer:
60% of the body is made up of water

Which organisms use photosynthesis to make their own food
Use an example from nature to explain how natural selection causes populations to change as their environment change include the following terms variation trait genes
Answer:
Galapagos finches have various beak sizes that make foraging for food more successful.
Explanation:
Organisms evolve over time due to changes in their genome. These are pontaneous, and occur in DNA at random. These changes are called mutations and form alleles or different forms of a gene.
Over time within a population, the number alleles increase the variation of the population. These variants may confer specific traits within an individual, that may confer a biological advantage.
Thus, the trait may make the organisms more capable of obtaining food, shelter a mate etc. or ensure survival, i.e. they are able to pass on their genes to the next generation.
Which biomolecule provides the instructions to build enzymes?
A. Carbohydrates
B. Lipids
C. Nucleic acids
D. Proteins
Proteins are the building blocks of enzymes, and proteins are made up of amino acids that are linked together in one or more polypeptide chains. Therefore, option (D) is correct.
What are enzymes?Enzymes are proteins that aid in the acceleration of metabolic processes, also known as the chemical reactions that take place in our bodies. They are responsible for the creation of some chemicals while also decomposing others. Enzymes are present in everything that is alive. Enzymes are something that are produced by our bodies spontaneously.
Enzymes regulate most biochemical reactions in animals, plants, and microbes, thus there are many examples. Animal digestive enzymes are well-known. Gastric juices break down food with the enzyme pepsin. Salivary amylase turns starch into sugar, starting digestion.

Answer:
1. False, That person should go to jail instead because the crime is not that bad
2. False, there should not be another trial unless the police have some evidence for it or if the person being trialed has confessed to whatever crime
3. False, the person needs to know what they did in order to learn their lesson.
Answer:
Situation 1: FALSESituation 2: FALSESituation 3: FALSEExplanation:
SITUATION: 1 The death penalty is only used in extreme cases. Depends in each state but a petty theft is never treated with that level of justice. If a person were to commit domestic terrorism or murder several people, kidnapping in WORST conditions, and the judge believes that it is better for the defendant to never go back to society, then execution is permitted.
SITUATION 2: A person who is tried for a crime they did not commit and found not guilty, will be set free. If the police try that same person again for the same reason, they will need proper evidence to try that individual. If found not guilty again, the person can take legal actions for invalid reasons of persecution and the police will be charged instead of the individual being wrongfully charged.
SITUATION 3: It is the law to be told why you are arrested. Even with a warrant with your name on it, you are fully allowed to read the warrant to verify if you are the correct suspect.
All interactions between the atmosphere and geosphere involve (3 points) soil and living things water and living things soil and gases or particles in air gases or particles in air and water
Answer:
Soil and gases or particles in air
Explanation:
The solid part of Earth is called its geosphere. The geosphere includes the rocks, minerals, and landforms of the surface and interior of our planet.
The atmosphere of Earth is the layer of gases that surrounds it. This layer of gases is what we call the air.
Based on this information, we can conclude that all interactions between the atmosphere and geosphere include the soil and gases or particles in the air.
In your Punnett Square activity, you chose beads which represented
genes and used Punnett Squares to determine possible offspring. If
your first parent genotype was yellow bead and blue bead and the
second parent genotype was blue bead and blue bead, how many
offspring out of 4 have the yellow kernel phenotype?
please please!!
Answer:
Two out of four offsprings have the yellow kernel phenotype.
Explanation:
The information that we have is that one parent's genotype is yellow bead (Y) and blue bead (B), and the other parent's genotype is blue bead (B) and blue bead (B).
Parent 1: YB
parent2: BB
If we make a Punnett Square, we can see that two out of four offspring will have the yellow phenotype.
║ B ║ B ║
Y║ YB ║ YB ║
B ║ BB ║ BB ║
The offspring out of 4 have the yellow kernel phenotype in the given case would be - two or 50%
We are given that the kernel color is represented by two beads, yellow and blue beads.
Let us consider yellow bead be represented as Y and blue bead be represented as y. Yellow color is dominant over blue kernel color.parent 1 has a genotype of a yellow bead and a blue bead represented as Yy.parent 2 has a genotype of the blue bead and blue bead, i.e, yy.The cross can be given as,
Genotype Y y
y Yy yy
y Yy yy
Now, two of the four offspring have Yy genotypes.
Thus, 2/4 or 50% of the offspring have a yellow kernel phenotype.

Birds belong to different species but share similar characteristics. What inference can be correctly drawn about this statement? (5 points)
Group of answer choices
All birds share the same habitat.
All birds produced similar offspring.
All birds reproduce with genetic variation.
All bird species adapt through evolution
Answer:
All bird species adapt through evolution
Explanation:
The correct answer would be that all birds reproduce with genetic variation and adapt through evolution.
Sexual reproduction causes genetic variation in sexually reproducing organisms due to crossing over and a random assortment of genes. Birds can only reproduce sexually and hence. they produce offspring that are genetically different but that might share many similar characteristics.
Evolution refers to the development of complex organisms from simple ancestral ones. Organisms change and evolve as they constantly try to adapt to their changing environments. Hence, organisms of the same species growing in a different environment might end up becoming different species as a result of adapting to their different environments, although they would still have some similarities to one another. In other words, evolution has a tendency to cause speciation.

Which part of photosynthesis is represented by the diagram to the right
Answer:
Light-dependent reactions
Explanation:
Photosynthesis occurs in two stages: light-dependent reactions and light independent-reactions. This last stage is often called Calvin cycle.
The diagram shows reactions occurred in the thylakoid membranes which are located inside the chloroplasts. Therefore, we can identify that these reactions are the light-dependent reactions. During this part of photosynthesis, the energy from the sunlight is absorbed by a pigment called chlorophyl (Chl). Then, it is sequentially coverted into chemical energy stored in the form of molecules: NADPH (nitotinamide adenine dinucleotide phosphate) and ATP (adenosine triphosphate).

How can both of these samples be pure phosphorus?
State your claim. Make sure your claim fully explains how the two samples can both be pure phosphorus. Summarize the evidence you have gathered to support your claim and explain your reasoning.
Answer:
If impurities are removed from the samples, pure phosphorus will be obtained.
Explanation:
Both of these samples be pure phosphorus if the atoms and other impurities are removed from chemical as well as physical means. Pure phosphorus means that there is only atoms of phosphorus present but pure phosphorus is not available because of its reactivity so for that reason it reacted with the oxygen present in the air and formed phosphate molecules and stabilize itself.

What would best describe the structure of the plasma membrane?
1.rigid (not flexible)
2.gaseous
3.solid
4.fluid (flexible)
Answer:
4. Fluid (Flexible)
Explanation:
Plasma membranes must be very flexible in order to allow certain cells, such as red blood cells and white blood cells, to change shape as they pass through narrow capillaries. The primary function of the plasma membrane is to protect the cell from its surroundings. Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells.

Nucleotides in a row on mRNA determine a specific amino acid in the polypeptide
Answer:
This statement is true. Nucleotides in the mRNA strand determine a specific amino acid, and its position, in the polypeptide.
Explanation:
Messenger RNA (mRNA) contains the information it has received from the DNA transcription, arranged in a nucleotide sequence, necessary to perform protein synthesis.
The sequence of nitrogenous bases in the mRNA can be distributed in trios of bases, called triplets or codons. Each of the codons encodes an amino acid, the beginning of the synthesis of a polypeptide or the completion of such synthesis. The order in which the nucleotides are found also determines the order or sequence of amino acids in a polypeptide.
