Answer:
Cytoplasmic inheritance
Explanation:
female variegated leaves × male green leaves ⇒ all variegated leaves female green leaves × male with white leaves ⇒ all green leaves female with white leaves × male with variegated leaves ⇒ all white leavesFrom these crosses, we can notice that only the female´s phenotype is expressed in the progeny, independently of the male´s phenotype. Whenever this occurs, it is probably due to the action of cytoplasmic inheritance.
Extrachromosomal or cytoplasmic inheritance refers to hereditability transmission controlled by cytoplasmic genes.
This form of inheritance lays in genes that are out of the nucleus. Even though most of the DNI is located in the nucleus, information for some characters is placed in organelles in the cytoplasm, such as mitochondria and chloroplasts. These organelles have a well-defined portion of the total cellular genome.
When a female expresses a trait that is defined by genes in the organelles, the whole progeny expresses the same trait as the female.
Mitochondrial inheritance is mostly maternal, but recent studies have demonstrated that it might also be paternal.
The described experiment is an example of Cytoplasmic inheritance.
What do you mean by Phenotypes?Phenotypes may be defined as the appearance or manifestation of a character. Phenotypes are also known as traits.
Cytoplasmic inheritance reveals the phenotypes of offspring according to female parents. In this mode of inheritance, characters or traits are stored in the organelles like chloroplast, and mitochondria, as well as in the cytoplasm.
Therefore, the described experiment is an example of Cytoplasmic inheritance.

Explanation:
The options include:
A. Epithelium
B. Thyroarytenoid muscle
C. Superficial layer of the lamina propria

Glucose molecules provide energy to power the swimming motion of sperm. In this example, the sperm are changingA) chemical energy into kinetic energy.B) chemical energy into potential energy.C) kinetic energy into potential energy.D) kinetic energy into chemical energy.E) kinetic energy into thermal energy.
Answer:
A
Explanation:
The correct answer would be that the sperms are changing chemical energy to kinetic energy.
In order to power the movement of the sperm cells, chemicals in the form of glucose molecules are hydrolyzed and the resulting energy from the reaction is used to power the movement of the sperm cells. Moving sperm cells possess kinetic energy. Thus, we can say that the chemical energy in the glucose molecules is converted to kinetic energy in the sperm cells.
The correct option is A.

Part Two: Position Paper What's your position about building roads in the rainforest? Write a paper that explains your position. Use facts from your research to support your position. How would humans and different parts of Earth be affected by the construction? Is there any argument against your position?
Answer:
We should not be building roads in the rain forest. Some reasons behind this include trees produce oxygen, animals leaving their natural habitat would not survive, and it would only increase pollution. Research states that if pollution increases any more, the Ozone protecting us will deteriorate. Other research states that if animals lose their natural habitat and have to adapt to a new environment, they are not very likely to survive. And not surviving means that the food chain will break, affecting everything above it, and that could also include us. This concludes why we should not build roads in rain forests.
Explanation:
Sorry if its short, but here <3
No roads should be build in the rainforests.
What do you mean by rainforests?
"A luxuriant, dense forest rich in biodiversity, found typically in tropical areas with consistently heavy rainfall."It's a moisture dependent vegetation.Why no roads?To build a road a vast area full of vegetation will be cut down.This will adversely affect the climate and habitats of organisms living there.This will also result in scarcity of rainfall.This results in interference of humans on the habitat of that area.Hence, building of road should be avoided in rainforests.

The transcription of genes in E. coli that lack a termination sequence require _______ factor to terminate transcription.
Answer:
rho
Explanation:
The Rho factor is a prokaryotic helicase protein that acts in bacteria to mediate the process of termination of transcription. In Escherichia coli, the Rho factor is a hexameric ring-shaped helicase and each subunit of this factor contains two domains involved in RNA binding and ATP hydrolysis. The Rho factor binds to the transcription terminator site on single-stranded RNA and then continues along the messenger RNA (mRNA) strand until it reaches the RNA polymerase, subsequently triggering its dissociation from the DNA and thus the termination of transcription.

During pulmonary ventilation, relaxation of the diaphragm and external intercostals ________ and air flows out of the lungs. increases the pressure in the thoracic cavity flattens the floor of the thoracic cavity increases the volume of the thoracic cavity expands the rib cage stimulates the phrenic nerve
Answer:
Increases the pressure in the thoracic cavity
Explanation:
During pulmonary ventilation, relaxation of the diaphragm and external intercostals increases the pressure in the thoracic cavity and air flows out of the lungs.
Pulmonary ventilation involves the exchange of air in the body. The exchange mainly takes place between the lungs and the the blood. When the lungs take in oxygen it distributes it to other parts of the body after which the byproduct is expelled in the form of Carbon dioxide.
The diaphragm and intercostal muscles are found close to the chest(thoracic) region such that when air is expelled it produces a similar effect such as relaxation of the diaphragm which also makes the chest muscles go down and exert pressure. This mechanism aids the expulsion of Carbon dioxide from the lungs.
1 poi A student draws a diagram of a plant cell. The diagram is 40mm in width. The plant cell is 0.02mm in width. What is the magnification of the student's drawing? A. 0.005 B. 0.08 C. x200 D. x2000
Answer:
D. x2000
Explanation:
magnification = image(drawing size)/actual size
magnification = 40/0.02
magnification = x2000
The magnification of the diagram is x2000. So, the correct option is (D).
What is Magnification?Magnification is the process of magnifying something. It enlarge the apparent size and not the physical size. This type of enlargement is certainly quantifiable. It also refers to the action of visually enlarging an object with the help of lenses.
This concept exist in two forms-
1. By microscope
It makes small objects appear large
2. By telescope
It makes a distant object which appear closer and the images are more clear and defined.
The formula of magnification represents the ratio of the height of the image to the ratio of the height of the object.
Magnification = image/actual size
For given example, magnification = 40/0.02
magnification = x2000
Thus, the magnification of the diagram is x2000. So, the correct option is (D).
