identify an independent variable in the experiment graphed in figure 1. based on the data in figure 1, identify a control that shows that sepin-1 rather than something else in the culture medium is inhibiting that growth of the cancer cells

Answers

Answer 1

Answer:

Explanation:

This question is incomplete because of the absence of the graph. However, the independent variable of an experiment is the variable that is not affected by any other variable during the course of the experiment but is however intentionally or unintentionally predetermined by the researcher conducting the experiment. For example, in an experiment to determine the effect of age on blood pressure; age is the independent variable because the age class/groups of the individuals to be used can be determined by the researcher also the age cannot be affected by the pressure (the age of a person cannot change because of an increase/decrease in blood pressure).

Also, the control of an experiment is the variable/data in which other data in the same experiment are compared to. For example, in an experiment to determine the effect of a substance (such as sepin-1) on the growth of cancer cells (using a culture medium), the control can be the culture medium that was not given any substance or the culture medium that was given a pure substance of no effect like water. This means, in this control culture medium, the cancer cells will continue to grow normally while that growth will be compared with what is seen in the culture medium treated with sepin-1.

Answers

Answer:

The correct answer is A.

Explanation:

Correct on edge :)

**it wouldn't hurt to mark brainliest!!

Producing a litter of puppies by mating two dogs of different breeds using genetic engineering is an example of hybridization. Thus, the correct option is A.

What is hybridization?

Hybridization is the process in which two complementary single-stranded DNA molecules or RNA molecules bond together with each other to form a double-stranded molecule of genetic material. The bonding is dependent on the appropriate base-pairing across the two single-stranded molecules of genetic material.

Interbreeding between individuals of different species within the same genus with favorable characteristics is called interspecific hybridization. For example, mule is produced from the cross between male donkey and female horse.

Therefore, the correct option is A.

why does mitochondria add acid to food in the digestive system?​

Answer:

Digestive system

The ribosomes is like the production of proteins

Explanation:

It serves as passage way of air into the lungs

Answers

Answer:

air travels down the pharynx (back of the throat), passes through your larynx (voice box) and into your trachea (windpipe). Your trachea is divided into 2 air passages called bronchial tubes. One bronchial tube leads to the left lung, the other to the right lung

Explanation:

Trachea

Explanation:

The trachea, commonly called the windpipe, is the main airway to the lungs. It divides into the right and left bronchi at the level of the fifth thoracic vertebra, channeling air to the right or left lung. The cartilage in the tracheal wall provides support and keeps the trachea from collapsing. The mucous membrane that lines the trachea is similar to that in the nasal cavity. Mucus traps airborne particles and microorganisms, and the cilia propel the mucus upward, where it is either swallowed or expelled.

Cells can benefit from diffusion even though it occurs naturally without action from a cell.
How can cells benefit from diffusion?
Cells increase concentration of certain molecules Cells achieve balance with their environment
Cells decrease concentration of certain molecules,
All of the above are correct
10
How does the cell membrane help to maintain the health of this cell? *

Answers

Answer:

See the answers below

Explanation:

Cells can benefit from diffusion in a variety of ways depending on what they need at a particular time. In some instances, cells might need to increase the concentration of certain molecules and as such, would require facilitated diffusion to achieve it. In some other time, cells might just need to achieve a balance/equilibrium or decrease the concentration of certain molecules within their bodies. Here, diffusion just needs to happen naturally without any facilitation.

Hence, all the options are correct.

Cell membrane helps to maintain the health of the cell because it acts as a selectively permeable interphase that allows for the passage of important materials and shuts the door to those that are not needed.

A. asexual
B. sexual
C. nonsexual

Answers

Answer:

The type of process is Asexual.

Explanation:

Because within simple living organisms, mitosis is a type of asexual reproduction .

Mitosis is an example of an asexual process. Thus, the correct option is A.

What is Mitosis?

Mitosis may be defined as a type of cell division in which the parental cell is divided into two daughter cells. Both synthesized daughter cells have the same kind and number of chromosomes.

In mitosis, the cell first makes the division of the nucleus and process known as karyokinesis, then the division of cytoplasm takes place and process known as cytokinesis.

And thus, the parent cell successfully divides itself into two daughter cells that are identical to one another.

Therefore, it is well described above.

Because gravity diminishes by the inverse square of the distance if you get away from the earth microgravity takes over.

Things orbiting Earth appear weightless but are actually falling around the Earth.  The Correct one is this

Gravity in space, or microgravity, is a tiny fraction of what it is on Earth.

Astronauts are able to float because they are out far enough from the Earth to escape gravity.

Just like an apple falls to the ground things in orbit are actually falling in the same way but are going fast enough so they continue to fall "around" the Earth.

Answer: The testing and release of genetically modified organisms (GMOs)—in particular GM plants—is tightly regulated internationally to prevent any negative effects on the environment or human health. However, these regulations are based on transgenic organisms and do not discriminate between transgenic plants and cisgenic plants, although we believe that they are fundamentally different Now, cisgenic plants fall under regulations designed for transgenic organisms, possibly because there have not yet been any applications for the approval of the deliberate release of cisgenic plants into the environment.

Covalent bonding can take place between atoms of the same element.​

Answers

Answer:      true

Explanation:

A covalent bond is the force of attraction that holds together two atoms that share a pair of valence electrons. Covalent bonds form only between atoms of nonmetals. The two atoms that are held together in a covalent bond may be atoms of the same element or different elements.

This question is incomplete because the options are missing. Here are the options:

A. True.

B. False.

A covalent bond occurs in two atoms when they join, to reach the "stable octet", and share electrons in the last orbit, forming a molecular orbital.

Covalent bonds are characterized by occurring

Between atoms of the same nonmetal element for example two or more atoms of carbon, nitrogen or argon bondedBetween different nonmetals, for example one atom of hydrogen bonded to one of carbon Between a nonmetal and hydrogen, for example one atom of hydrogen linked to one of nitrogen

Therefore, the statement that a covalent bond can be formed between two equal elements is true.

D.Few theories from previous eras are actually valid.

Answers

Answer:

Theories are sometimes disproven because new discoveries show they are incorrect.

Explanation:

In science, theories constitute the explanations to natural phenomena, with an experimental base and whose variables are congruent, allowing to make inferences, explanations and to raise predictions of the reality to which this theory is applied.

All theories are susceptible to be refuted or substituted by a more solid approach.  A theory is maintained and is valid only until new experiments or established theories detract from its validity or substitute it.

Other options are not correct because:

    B. The scientific method does not experiment changes over time.

   C. Updated mathematical formulas do not relate to the validity of a theory.

   D. It is unlikely that theories from other eras are currently valid.
