Answer:
creating a hypothesis
Explanation:
The scientific method is a logical and systematic procedure used to understand phenomena from the real world. The scientific method involves several sequential steps: 1-to observe and pose a question on a particular phenomenon from the real world, 2-to raise a hypothesis or 'explanation' to these observations (this explanation allows to obtain a predictive pattern in order to explain further observations), 3-to test the hypothesis by experimental procedures or further empirical observations, 4-to analyze and interpret data (results), and 5- to reach to a conclusion that confirms or rejects the working hypothesis. A good hypothesis must be 1-plausible (i.e., it is scientifically adequate and appropriate), 2-falsifiable (i.e., it may have a negative answer) and 3-testable (i.e., it must be proven by scientific data).

of the diffusing substance?
O (1) size
O (2) shape
O (3) color
O (4) temperature
Answer:
4
Explanation:
Higher temperatures increase the energy and therefore the movement of the molecules, increasing the rate of diffusion. Lower temperatures decrease the energy of the molecules, thus decreasing the rate of diffusion

The movement of a substance through the cell membrane that requires energy.
Answer:
The correct answer is - active transport.
Explanation:
Active transport is the movement of a substance that crosses the cell membrane against the concentration gradient and therefore requires energy in the form of ATP. In contrast, passive transport does not require energy for the movement of a substance through the cell membrane as it moves to the concentration gradient.
This movement of molecules is towards the region of high concentration from the region of lower concentration through the cell membrane by elcectrochemical gradient or ATP.

Option F. It is moist and cool with decaying debris.
Answer:
F. It is moist and cool with decaying debris.
Explanation:
I know this because an earth room always needs their supplement from the dirt in order to stay moist and wet during any weather.
Leucine biosynthesis occurs in a multistep pathway starting from 2-oxovalerate, and the final product of the pathway (leucine) inhibits the first enzyme involved in the biosynthetic pathway through a process called feedback inhibition. This enzyme inhibition occurs, regardless of whether or not the 2-oxovalerate substrate is bound in the active site of the enzyme. Describe what type of inhibitor leucine is and justify your response.
Answer:
it is a type of mixed inhibition referred to as 'non-competitive inhibition'
Explanation:
Mixed inhibition occurs when an inhibitor binds to the enzyme in a site different from the active site where the substrate binds (i.e., the allosteric site). The term 'mixed' is because this inhibition is a mixture of competitive inhibition, where the inhibitor competes with a substrate to bind to the enzyme, and uncompetitive inhibition, where the inhibitor binds only to the complex formed between the enzyme and its substrate. In competitive inhibition, the maximal velocity of the reaction (Vmax) does not change, whereas the apparent Km (i.e., the concentration of substrate which permits the enzyme to achieve half Vmax) increases. Moreover, in non-competitive inhibition, the Km does not change, whereas the Vmax decreases. Non-competitive inhibition is a special type of mixed inhibition where the apparent Vmax (V app-max) is reduced, while the Km of the enzyme is unaffected.

Answer:
D. the dolphin in the back diverge under different selective pressures, which accounts for their difference
Explanation:
I hope this is helps you
Dolphins and bats share a common ancestor that is more recent than the one shared with birds.
Homologous bodiesHomologous organs are those that may or may not perform the same function, but have the same basic structure and the same embryonic development. This means, therefore, that individuals who have these organs have shared ancestry.
Whit this information, we can conclude that dolphins and bats share a common ancestor that is more recent than the one shared with birds.

What is cell specification?Cell specification is the process by which a cell determines its fate. After specification, a cell's gene pattern changes. Some genes that are present in euchromatin regions are expressed, and as a result, this cell expresses specific proteins and RNA.
After the zygote is formed, it undergoes a cleavage process to form multiple cells by mitosis. The cells then specify and receive their fate, such as some converting into nervous cells, others into epithelial cells, and still others into blood cells.
This change in structure and function is due to the expression of special genes in DNA. Though all cells have the same genetic content, some genes are present in euchromatin regions and some genes are present in heterochromatin regions. Genes of euchromatin are expressed.
Hence, option E is the correct answer, as the cell produced specific transcription factors.

The genetic code was elucidated through the use of polyribonucleotide's synthesized either enzymatically or chemically in the laboratory. Given what we now know about the genetic code, how would you make a polyribonucleotide that could serve as an mRNA coding predominantly for may Phe residues and a small number of Leu and Ser residues?
What other amino acid(s) would be encoded by this polyribonucleotide, but in smaller amounts?
Answer:
The genetic codes are responsible for coding the amino acids. The messenger RNA (ribonucleic acid) consists of triplet codons, which is responsible for the synthesis of respective amino acid sequences. The UUU codes for the phenylalanine amino acids. Similarly, the incorporation of 5 mixtures such as ADP, GDP, CDP, and UDP can alternatively produce the mRNA polymer with the serine and lysine residue in a small amount.
EXPLANATION:
The genetic codes are responsible for coding the amino acids. The messenger RNA (ribonucleic acid) consists of triplet codons, which is responsible for the synthesis of respective amino acid sequences. The formation of the RNA stand is done by using ADP, GDP, CDP, and UDP (adenosine, guanosine, cytosine, and uridine diphosphate). It requires no template for the formation of polymers. Therefore incorporation of UDP is done by the incorporation of polynucleotide phosphorylase, which will result in the formation of poly U. The UUU codes for the phenylalanine amino acids. Similarly, the incorporation of 5 mixtures such as ADP, GDP, CDP, and UDP can alternatively produce the mRNA polymer with the ser and lysine residue in a small amount. For example in the stretch of polynucleotide UUU presence of one of the following codon UUA, UUG, CUU, CUC, CUA, CUG as well as UCU, UCC, UCA, UCG, and AGU can synthesize leucine and serine residues. (UUC)n can synthesize the polymer of phenylalanine, serine, and incorporation of few A and G will synthesize leucine. However, the presence of A, C, and G can also synthesize a small amount of tyrosine, isoleucine, and cysteine residue.
1) Identify 4 stimuli that cause a decrease in the number of producers, consumers, and decomposers living in an area.
2) What could be the effects in relation to the energy pyramid, population, and community of organisms within the environment.
Answer:
Temperature, humidity, food and water.
Explanation:
Temperature, humidity, food and water are the four stimuli that is responsible for the decrease in the population of producers, consumers, and decomposers living in that area. If the temperature is too high or too cold, the growth of the producer stops and the plants can't tolerate the temperature will die. The death of producers causes the death of consumers because consumers depend on these producers for food. The population of decomposer also decreases if the environment is too harsh because decomposers also requires suitable environment for growth and survival. There is adverse effect on the energy pyramid, population, and community of organisms within the environment if these stimuli are not present in suitable range.

O C. placental
O D. multipotent
Answer:
I think it it c
Explanation:
if not I'm sorry
The zygote is basically an example of totipotent cell in humans. The correct option is B.
What is totipotent cell?Cell potency refers to a cell's capacity to distinguish into various types of cells. The greater a cell's potency, the more cell types it can differentiate into.
A totipotent cell is a single cell that, when given the proper motherly assistance, can give rise to a new organism.
A totipotent cell is one that can generate all extraembryonic tissues, as well as all body tissues and the germline.
The term "totipotent" refers to a cell that has the ability to split and produce all differentiated body cells, both embryonic and extraembryonic.
Zygotes and spores are instances of totipotent cells in animals.

Rocky's class recently got pet turtles. When putting together the habitat, decomposers were added to the soil, as well as some smaller organisms that turtles eat. Some students wanted to get "fake" plants for the terrarium, but Rocky insisted that this would negatively affect the carbon and oxygen cycles.
Which of the following reasons support why Rocky is correct?
Group of answer choices
A) Carbon won't be removed from the air.
B) Photosynthesis won't occur.
C) The turtles won't be able to breathe.
D) All of these are correct.
Will mark as brainliest if correct
Answer:
The correct answer is - D. All of these are correct.
Explanation:
It is clear that the terrarium is sealed or not, if it is open to the outside environment or not. Considering it sealed and no outer interaction, then if a fake plant to this terrarium then there will be no photosynthesis will take place as there are no green plants to capture the sunlight and make glucose and no way to release oxygen for the other organisms.
If in this no green plants then the removal of CO2 will not be possible. Higher amount of carbon and without oxygen turtles would not be able to survive even though there is food for them.

We spent quite a bit of time discussion the various types of vaccines available this week, and how each of them compare and contrast with each other. However, ALL vaccines have a common purpose, regardless of how they aim to accomplish it. In YOUR OWN WORDS, tell me what that common purpose is. This is a short answer question and should be answered in a sentence or two, maybe three at the most.
Answer:
All vaccines work together to accomplish one main task and that is to prepare your body incase it gets invaded with a harmful virus that could cause you to get very sick. Vaccines are weak forms of the virus that are injected into humans so that the body can start creating the right antibodies to defend the body against the harmful virus.
