Mammal 2 and 4 are most related, why?
Explanation: They have TCT, CAG, CTG and CA, the only ones it doesn't have is the last ones, A and G, making it the only difference. 1 has 2 differences to 2, 3 differences to 4, and 3 has 2 differences as well, therefore 2 and 4 have the least differences.
Answer:
2 and 4
Explanation:
You can see their patterns match except for the last letters of 2 and 4

Explanation:
For the growth curve to continue increasing, which of these must occur?
The environment must provide a habitat for a large variety of organisms.
The organisms must migrate to a new environment.
The organisms must adapt to a new habitat.
The resources in the environment must be unlimited.
Answer:
Out of all the answer choices I would say the answer is A: The environment must provide a habitat for a large variety of organisms. i hope this helped you.
Explanation: This is because it would not make sense for the orginisms to move and we can say that the 3rd answer is true but it doesnt make the most sense and we can also eliminate the last one

Alligators live in swamps. They are able to lie so still that the look like floating logs in the
water. How does this adaptation help the alligator survive?
Answer:
Modern alligators have many adaptations to make them well suited for their wetland environment. These plates are extremely thick and well adapted for their environment. Their skin camouflages very well with their environment and along with the bulging eyes this makes them look like a log!

6. explain the relationship between temperature and pressure. why do you think this occurs?
Answer:
The pressure of a given amount of gas is directly proportional to the temperature at a given amount of volume. When the temperature of a system goes up, the pressure also goes up, and vice versa.
Explanation:
This occurs because of the pressure temperature law. (or also known as the Gay-Lussac's law)

Explain how genetic mutations may result in genetic and physical variations differences) within a population.
Answer:
The correct answer is - Mutations produce different versions of genes.
Explanation:
Mutations are the changes in the gene or DNA of an organism that leads to the production of different version of genes and proteins. Mutations result in genetic variation or physical variation within the population as it introduces new alleles in the populations.
Mutations introduce or remove various versions of genes called alleles within a population and increases genetic variation. These changes in the genes are the source for new genetic variation. Genetic or physical variation does not occur without mutations.
cual es la diferencia netre los cloroplastos y la cianobacteria si ambos son bacterias fotosinteticas???
Answer:
Encontré esto en un texto de microbiología, tal vez sea útil.
Explanation:
"Las cianobacterias y los cloroplastos de las plantas tienen ambos fotosistemas, mientras que las bacterias fotosintéticas anoxigénicas sólo utilizan uno de los fotosistemas. Ambos fotosistemas son excitados simultáneamente por la energía luminosa. Si la célula requiere tanto ATP como NADPH para la biosíntesis, entonces llevará a cabo una fotofosforilación no cíclica".
Si estoy equivocado, pido disculpas. También lo he sacado de un traductor así que si suena mal también me disculpo por ello.
A single gene mutation results from
Answer: DNA changes in one particular gene
Explanation:
Single gene disorders are caused by DNA changes in one particular gene, and often have predictable inheritance patterns. Over 10,000 human disorders are caused by a change, known as a mutation, in a single gene. These are known as single gene disorders.
The level in the biosphere that includes abiotic factors
a.community

Explanation:
Please transcribe this DNA code into the complementary
RNA code.
TCG GGG CTA ATC AAG
The transcribed code for the DNA as complementary to the RNA code is AGC CCC GAU UAG_ UUC . Th the option D is correct.
What is the RNA code?The RNA code is made of four nucleotides that are adenine, guanine, the cytosine, and the uracil. The code makes a unit known as a codon which forms the amino acid. The RNA consists of a code that is kept by the cell DNA and signals the formation and end of the protein synheis.

Answer:
false
Explanation:
When the concentration of a solution is higher inside a cell than it is outside of the cell, is the solution inside hypertonic,isotonic, or hypotonic?
Answer:
Hypertonic solution
Explanation:
Hypertonic solution refer to the solution of a cell if the solute concentration is higher inside than outside and it cannot cross the membrane. In Hypertonic solution, Water crosses the cell membrane in both directions which result in more b water leaving the cell than entering it. Therefore, a cell place in this solution will shrink due to exosmosis.
