When you do an experiment and come up with something that works, you...A. have a conclusion in which your hypothesis is correct
B. are doing research
C.have bias because you wanted to be right
D.are making inferences

Answers

Answer 1
Answer:

When you do an experiment and come up with something that works, you are making inferences. Thus, the correct option for this question is D.

What is an Experiment?

An experiment may be defined as a complete methodology that is carried out under a controlled environment in order to discover an unknown effect or law, test or establish a hypothesis, or illustrate a known law.

An inference may be defined as a conclusion that is remarkably based on observations. They are important in order to find the exact demonstration of the experiment on a specific topic to deduce a conclusion.

Without inference, one must treat what they hear or read in a very literal sense. But inferences make a more accurate and valid conclusion.

Therefore, when you do an experiment and come up with something that works, you are making inferences. Thus, the correct option for this question is D.

PKU (Phenylketonuria) is an autosomal recessive disease, in which the synthesis of amino acid Tyrosine from Phenylalanine is blocked. As a result, an excess of Phenylalanine gets converted into phenylketones, which appear in the urine. In severe conditions it may also result in damage to the brain.The gene responsible for this is p, whereas the gene P is responsible for normal synthesis of Tyrosine. In a small population of Brazilian natives, the frequency of gene p, responsible for this disease, is 0.3. What must be the frequency of people who are heterozygous for this disease?

The cell membraneprovides storage in the cell
acts as a barrier
provides energy for all of the internal organelles
resides within the nucleus

Answers

cell membrane is like your skin in a way, it holds the cel together and determines what goes in an out

technically, it could provide storage since it stores the contents of the cell, but this would be the vacuoles

acts as a barrier: this wold be the answer

provides energy: this is mitocondria's job

resides within te nucleous: this is the outside, it's like saying that your skin is all inside your brain



best answer would be acts as a barrier
The cell membrane acts as a barrier because it blocks any "invaders" from coming into the cell, the same way our skin protects any "invaders" from harming our organs inside our body.

in 2002, the fossil of a four- winged dinosaur was discovered in china and named a microraptor. what was the significance of the discovery

Answers

The answer is: the discovery resulted in some theories about the origin of flight.

Microraptor was a four-winged dinosaur, that lived about 120 million years ago. It is suggested that it was able to fly using all for limbs. It also had feathers, which suppose the connection between birds and dinosaurs. But, its feathers are used for gliding and not for flying. This suggests that flight evolved in the trees and not on the land.

Answer: alleles

Explanation:

Alleles are different forms of a given gene. Alleles are mutated forms of a given gene which controls a particular trait. For instance, the gene that codes for hemoglobin is denoted with the letter A but the gene has another variant denoted by S. In abnormal hemoglobin S (sickle hemoglobin), glutamate is replaced by valine at position 6 in the amino acid sequence of the two beta chains of hemoglobin. This change in the amino acid sequence causes the red blood cells to have a sickle shape resulting in sickle cell disease. Therefore hemoglobin A and S are alleles of a given gene.

Fill in the blank: ·In every energy transformation, some____ is released.
·When you climb a rope, you change ____ energy into ____ energy.
·In the muscle cells in your body, ____ energy is changed into ____ energy.
Any that you know would help!

Answers

In every energy  transformation, some THERMAL ENERGY is released. When you climb a rope, you change CHEMICAL ENERGY INTO KINETIC ENERGY. In the muscles cells in your body, CHEMICAL ENERGY is changed into KINETIC ENERGY.
Energy can neither be created nor destroyed, because of this, energy usually remain constant but it can be converted from one form to another.

Some species of bees help flowers reproduce by transferring pollen from one plant to another. Flowers provide a source of food, such as nectar or pollen, for the bees.Which term BEST describes the symbiotic relationship between bees and flowers?
A
commensalism

B
mutualism

C
parasitism

D
predation

Answers

Answer:

Option B. mutualism

Explanation: Mutualism is a symbiotic association in which both the organisms gets benefits from one another. Bees helps in the pollination by transferring pollen grains from one plant to another and in return the flowers provide food in the form of nectar to the bees and in this way both the organism gets benefited. So the relationship which is present between flower and bees

is Mutualism.

Which summary best explains the mechanisms that control the cell cycle in multicellularorganisms?
The type of DNA in each cell controls the rate of the cell cycle and the specific type of cells
formed
The size of the cell determines the number of cells that will be produced from each cycle.
Internal and external signals regulate the progression of the cell cycle at various critical
checkpoints
Hormones signal the start of the cell cycle, and DNA determines how the cell differentiates.

Answers

Answer:

The correct answer is internal and external signals regulate the progression of the cell cycle at various critical check points.

Explanation:

The cyclic event that helps to prepare the cell for division is termed as cell cycle.Cell cycle are regulated by various internal and external factors which regulates the passage of cell through various critical check point.

 For example Maturation promoting factor helps in the progression of frog egg oocytes cells from G2 to M phase.

    G1 cyclin CDK helps in the passage of cell from G1 to S phase.
