what happens to the i band when the sarcomere contracts
Answer:
The A band stays the same width and, at full contraction, the thin filaments overlap. ... The I band contains only thin filaments and also shortens. The A band does not shorten—it remains the same length—but A bands of different sarcomeres move closer together during contraction, eventually disappearing.

How do hydrogen ions get transferred from the Light Reaction to the Calvin Cycle?
Answer:
A photon of light hits chlorophyll, causing an electron to be energized.
The free electron travels through the electron transport chain, and the energy of the electron is used to pump hydrogen ions into the thylakoid space, transferring the energy into the electrochemical gradient.

nucleic acids are assembled in the _____ direction.
Nucleic acids are assembled in the 5' to 3' direction during DNA replication. DNA replication is the process of duplication of DNA molecule.
What are Nucleic acids?Nucleic acids are the biomolecules occurring in the chemical compounds which serve as the primary information-carrying molecules in the cells. Nucleic acids play an important role in directing the process of protein synthesis. The two main classes of nucleic acids include deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Nucleic acids can only be synthesized in vivo in the 5′-to-3′ direction and these can be assembled in the same direction in cell, as the polymerases which assemble various types of new strands generally rely on the energy which is produced through breaking the nucleoside triphosphate bonds to attach these new nucleoside monophosphates to the 3′-hydroxyl (−OH) group, through a phosphodiester bond.

Explanation:
what can be said about altitude, atmospheric pressure, and the partial pressure of oxygen? check all that apply.
As both altitude and atmospheric pressure increase, the partial pressure of O2 will decrease.
Though I could not locate the options online to provide an exact answer, I can offer a general overview of the question at hand.
The interactions between altitude and the partial pressure of oxygen are inversely proportional. This means that as one increases, the other will decrease. The proportion of oxygen is 21% of the air content at all altitudes. However, as the altitude increases, the atmosphere becomes thinner, meaning that the partial pressure of O2 will decrease given that 21% of a thinner atmosphere results in less oxygen.
On the other hand, the relationship between atmospheric pressure and oxygen is that they are directly proportional. This means that as one decreases, the other does as well. In this case, since atmospheric pressure is the sum of the partial pressures of all gases, we can conclude that as it decreases, so to will the partial pressure of oxygen.

Explain the relationship between these terms photosynthesis chlorophyll thylakoids chloroplasts
Answer:
In photosynthesis, oxygen, carbon dioxide, ATP, and NADPH are reactants. GA3P and water are products. In photosynthesis, chlorophyll, water, and carbon dioxide are reactants. GA3P and oxygen are products
Answer:
Photosynthesis occurs in the chloroplasts.
Chloroplasts capture light energy.
Thylakoids can be found inside chloroplasts, where light-dependent reactions occur.
Chlorophyll is found in the thylakoids.
Chlorophyll absorbs light energy.
Chlorophyll is what makes plants look green.

Explanation:
G3P
This process is called carbon fixation, because CO2 is “fixed” from its inorganic form into organic molecules. ATP and NADPH, which were made during the light dependent reactions, use their stored energy to convert carbon dioxide into a three-carbon compound called G3P.

If a hom.ozygous white horse [tex]C^WC^W[/tex] and a hom.ozygous black horse [tex]C^BC^B[/tex] are bred together, what is the likelihood that their offspring will be roan with both colors represented in their hair if this gene follows a codominant inheritance pattern?
A.) 50%
B.) 25%
C.) 100%
D.) 0%
Answer:
c
Explanation:
looked at the answer when i finished the test and got it wrong lol
The roan coat color in horses is also an example of codominance. A “red” roan results from the mating of a chestnut parent and a white parent. Therefore, option (C) 100% is correct.
What is co-dominant inheritance?In the genetic phenomenon known as codominance, both alleles of a gene pair found in a heterozygote are allowed to fully express themselves. Because of this, the phenotype of the offspring is a combination of the phenotypes of both the mother and the father. As a result, the trait does not exhibit dominant or recessive characteristics.
The blue roan horse has hair that is both white and gray, whereas the red roan horse's hair is both white and a reddish-brown color. The hairs of the offspring take on the coloration of both of its parents' coats. This is a situation of co-dominance.
Therefore, the resulting heterozygous progeny will have a 100% codominant inheritance pattern.

what is the most dangerous plant known by man kind?
Answer:
1). The oleander, also known as laurel of flower or trinitaria, is a shrub plant (of Mediterranean origin and therefore, resistant to droughts) with intensely green leaves and whose leaves, flowers, stems, branches and seeds are all highly poisonous, hence it is also known as "the most poisonous plant in the world".
2). The Dendrocnide Moroides is known as "the world's most dangerous plant," with even morphine rendered ineffective against its venom, Nature reports. The shrub has numerous names including the Gympie Gympie, Stinging Bush, Queensland Stinger and the Giant Australian Stinging Tree.
