If population remain geographically isolated for thousands of generations, what would happen?
Answer: They would die, or go insane
Explanation: First off, they need to have a steady food supply to maintain society. If, lets say, the food ran out, then everyone would die as they were isolated and had no other food source. Since the human body needs to have interaction, if a certain group of people were isolated, they would most likely also go insane due to the lack of no other people. Of course, the info you gave was very vague, so I couldn't really give a good answer, so yeah
A test cross to determine the genotype of a green-colored seed would best be represented by _______.
a. Yy x Yy
b. YY x YY
c. YY x Yy
d. Yy x yy
Answer:
d. Yy x yy
Explanation:
In Mendelian inheritance, a TEST CROSS is a cross used to determine the actual genotype of a dominant phenotype. The test cross is usually performed between the unknown genotype and a recessive genotype. If all the offsprings are dominant, the unknown genotype is the same allele but if the offsprings are half dominant and half recessive, the unknown genotype is HETEROZYGOUS.
In this case, a test cross to determine the genotype of a green-colored seed would best be represented by Yy × yy because a test cross must include a recessive genotype, which is "yy" in this case.

Why is it important for organisms to get rid of waste?
There are different types of waste such as carbon dioxide and that must be removed. If they are allowed to accumulate they can and will cause poisoning which slows down vital chemical reactions. When excretory organs such as your kidney's are damaged, the organism quickly displays symptoms of poisoning and death is rapid unless treated immediately.
Label the nucleotide correctly
C
* phosphate
:: deoxyribose sugar
nitrogenous base
Answer:
Nucleotides comprise:
a 5-Carbon deoxyribose sugar, one nitrogenous base (adenine, guanine thymine, and cytosine) and a phosphate group.Explanation:
Nucleotides are monomers that makeup DNA- a nucleic acid that functions as a storage molecule for encoding proteins, along with RNA a ribose sugar-containing nucleotide. Nucleotides contain a 5-carbon deoxyribose or ribose sugar, phosphate and one of four nitrogenous bases:
Adenine (A)Guanine (G)Cytosine (C)Thymine (T). Uracil (U) found in RNAEach nucleotide derives its name from its nitrogenous base. The nucleotides on a single strand polymerize via covalent bonding. This occurs between two nucleotides in an esterification reaction where a phosphodiester bond is formed. In double helix formation, base pairs form hydrogen bonds with each other.

O All genes are made of proteins, proteins code for DNA DNA carries out life functions
As
Answer:
Genes are made of DNA; DNA codes for proteins; proteins carry out life functions
Explanation:
The correct statement is "All DNA is made of genes: DNA codes for proteins: proteins carry out life functions"
The deoxyribonucleic acid (DNA) chain is known as a gene, a structure that is constituted as a functional unit in charge of the transfer of hereditary traits.DNA is the biopolymer that houses the data for the synthesis of proteins and that makes up the genetic material that cells have.The functions of proteins are specific to each of them and allow cells to maintain their integrity, defend themselves from external agents, repair damage, control and regulate functions, among other life functions.Therefore, we can conclude that DNA stores the instructions for the synthesis of all the proteins that make up an organism and the minimum units of this genetic information are called genes.

Given that almost all organisms obtain energy from food by the process of cellular respiration, which is the most likely explanation for what prevents Earth from running out of oxygen?
A. The net effects of the reactions of photosynthesis and cellular respiration are the opposite of one another, therefore the products of one are the reactants of the other, creating a cycle.
B. The energy flow—and thus oxygen flow—for cellular respiration and photosynthesis take place in the same direction, and therefore build upon one another.
C. Cellular respiration is a process that releases energy and oxygen, while photosynthesis withdraws energy and uses oxygen, therefore keeping each process in balance.
D. Oxygen readily accepts electrons, so cellular respiration uses a negligible amount of oxygen.
the answer would be A
The net effects of the reactions of photosynthesis and cellular respiration are the opposite of one another, therefore the products of one are the reactants of the other, creating a cycle. Hence option A is correct.
What is photosynthesis?Photosynthesis is defined as the process through which green plants use energy from sunlight to transform carbon dioxide and water into food. The process of photosynthesis is used by plants, algae, and some microorganisms to convert light energy into chemical energy. Photosynthesis is a process, not an event. Every time sunshine is present, it happens continually.
Specifically, glucose-stored energy is converted to ATP during cellular respiration. The chemical energy the cell can use is called ATP, or adenosine triphosphate. It is the molecule that gives your cells the power they need to carry out tasks like contracting your muscles when you walk down the street.
Thus, the net effects of the reactions of photosynthesis and cellular respiration are the opposite of one another, therefore the products of one are the reactants of the other, creating a cycle. Hence option A is correct.

Which macromolecule provides the energy that starts glycolysis?
ATP
sugar
carbon dioxide
water
Answer:
It starts with sugar, or C6H12O6 being broken down.

What would happen to a bunch of balloons that were inflated outside when it was 95 degrees F and you took them into an ice hockey rink where it was 45 degrees F *
Answer:
The balloon shrinks
Explanation:
According to Charles law, temperature and volume are directly proportional. When temperature increases, volume of the gas inside the balloon increases and vice versa at constant pressure.
However, when the balloons are taken into an ice hockey rink and their temperatures drop from 95 degrees Fahrenheit to 45 degrees Fahrenheit, the molecules of gas in the balloons loose energy and move at slower speeds tending to stick closer together. The volume of the balloon therefore decreases accordingly. This means that the balloon shrinks.
