The non-seed structure in seed plants that made them even more water-reliant than seedless vascular plants is the protective coat or seed coat.
This layer of protection around the embryo keeps the embryo safe and moist, allowing it to survive in a variety of environments. It also helps to conserve water by preventing the embryo from drying out.
Furthermore, the seed coat can retain nutrients and water, which can help the seedling to grow faster and stronger when the seed is planted.
In addition, the seed coat can also provide protection from predators and disease. All of these features work together to make the seed plants more water-reliant than seedless vascular plants.

retrotransposon (short inverted/directly repeated long terminal repeats at both ends, requires ____ to move, how does it replicate?)
Retrotransposons are a type of transposable element that move within a genome via an RNA intermediate. They are characterized by short inverted/directly repeated long terminal repeats (LTRs) at both ends, which play a critical role in their replication and movement.
To move, retrotransposons require an enzyme called reverse transcriptase, which is encoded by the retrotransposon itself. The reverse transcriptase enzyme allows the retrotransposon RNA to be converted back into DNA, which can then be inserted back into the genome at a new location. This process is known as retro transposition and is the basis of the movement of retrotransposons within a genome.

what does the neural tube become after neurulation?
After neurulation, the neural tube becomes the central nervous system, which includes the brain and the spinal cord.
Neurulation is the process by which the neural plate folds and closes to form the neural tube during embryonic development. The process of neurulation begins when the underlying dorsal mesoderm (and pharyngeal endoderm in the head region) signals the ectodermal cells above it to elongate into columnar neural plate cells.
This process is called primary neurulation, and it begins with an open neural plate, then ends with the neural plate bending in specific, distinct steps. These steps ultimately lead to the neural plate closing to form the neural tube.
Neurulation is a process in which the neural plate bends up and later fuses to form the hollow tube that will eventually differentiate into the brain and the spinal cord of the central nervous system.

What are the steps of pyruvate oxidation carried out by (enzyme)?
Steps in pyruvate oxidation:
Pyruvate undergoes enzymes with the removal of a carboxyl group and releases carbon dioxide.As the first step's two-carbon molecule is oxidized, NAD+ takes the electrons to create NADH.Coenzyme A is joined with the two-carbon oxidized molecule, an acetyl group, to create acetyl CoA. Pyruvate undergoes the removal of a carboxyl group. It releases CO2. NAD+ is converted to NADH in 2. 3. Coenzyme A receives a transfer of an acetyl group, resulting in acetyl CoA.
After glycolysis, pyruvate is transferred to the mitochondria where it is oxidized inside the mitochondrial matrix. Pyruvate is created during glycolysis and reaches the mitochondria where it starts the process of aerobic respiration. The transformation of pyruvate into acetyl CoA signals the start of aerobic respiration. Decarboxylation is the first of three processes in this reaction.

_____ does not use water as an initial electron source for the light dependent reactions
non-cyclic photophosphorylation pathway does not use water as an initial electron source for the light dependent reactions.
A excited electron is passed through a series of electron carriers after being absorbed by photosystem I, eventually landing in NADP+ to form NADPH. In contrast to the oxygenic photosynthesis pathway this process does not require splitting water molecules in order to produce electrons. A different method of generating ATP and NADPH that does not require the division of water molecules is non-cyclic photophosphorylation.
In this pathway, photosystem I serves as the main electron donor. The electrons are then transferred through a number of electron carriers, such as ferredoxin and the enzyme NADP+ reductase, before being used to convert NADP+ to NADPH.

A husband and wife have normal vision, although both of their fathers are colorblind. What is the probability that their first child will be a daughter who is colorblind?
The probability of the next child being a son who has normal vision and is blood type A is 25%, assuming the parents are both heterozygous for the A allele.
The chance of having a son is 50%, and the chance of having a child with the A blood type is 75% (since both parents are type A). However, since the previous son was colorblind, he must have received a recessive X allele from his mother (who is a carrier), which means there is a 50% chance that the next child will also receive that same X allele and be a daughter who is a carrier for color blindness.
The proportion of offspring that will be mutant in phenotype for all four markers is 1/32 or 0.03125. This is calculated by multiplying the probability of each individual marker being mutant (1/2 for the X-linked markers and 1/4 for the autosomal markers), since the inheritance of each marker is independent.
The probability of the next child being a female who has normal vision and is type O is 25%, assuming the parents are both heterozygous for the A allele. The chance of having a daughter is 50%, and the chance of having a child with the O blood type is 25% (since both parents are type A and carry the O allele).
Since the scalloped female is wild type for ebony, she must be[tex]X^sX^[/tex]+ and the male must be ee.

contrast cardiovascular and metabolic dynamics during upper-body versus lower-body exercise
The cardiovascular dynamics during upper-body exercise result in a higher heart rate and blood pressure compared to lower-body exercise, while the metabolic dynamics show a greater reliance on anaerobic metabolism for energy production in upper-body exercises and aerobic metabolism in lower-body exercises.
Cardiovascular dynamics:
1. Upper-body exercise: During upper-body exercise, the heart has to work harder to pump blood to the muscles involved, resulting in a higher heart rate and blood pressure than during lower-body exercise. This is because the upper body has relatively smaller muscles and a greater reliance on the arms.
2. Lower-body exercise: Lower-body exercise typically involves larger muscles, such as the legs and glutes, which require a more significant amount of blood flow. However, the heart doesn't have to work as hard to pump blood to these areas, leading to a relatively lower heart rate and blood pressure.
Metabolic dynamics:
1. Upper-body exercise: Upper-body exercises generally involve shorter-duration, higher-intensity movements, which rely more on anaerobic metabolism for energy production. Anaerobic metabolism primarily utilizes glucose and glycogen stored in the muscles.
2. Lower-body exercise: Lower-body exercises often consist of longer-duration, lower-intensity movements, which rely more on aerobic metabolism for energy production. Aerobic metabolism uses a combination of carbohydrates, fats, and oxygen to produce energy for the working muscles.
