H₂O molecule (labeled a) that is removed from monomers during dehydration synthesis to create the disaccharide.
Dehydration synthesis :A water molecule is released during the process of making larger molecules out of smaller monomers, which is known as dehydration synthesis. This can be applied to the synthesis of big biological molecules like triglycerides and carbohydrate polymers, as well as artificial polymers such polyethylene terephthalate (PET).
The dehydration synthesis reaction is used in a wide range of biological or chemical activities. Examples include the conversion of monosaccharides like glucose into disaccharides like sucrose and the condensation of alcohol to produce ether. A dehydration synthesis reaction may be catalyzed by an acid.

The cell theory includes different tenets to explain the organization of life. what principles comprise the cell theory? check all that apply.
The principles that comprise the cell theory are:
(i) All living organisms are composed of cells and products of the cells.
(ii) All cells arise from pre-existing cells.
In 1838, Matthias Schleiden, a botanist, did research on plants and discovered that all plants are made of cells.
At around the same time, Theodore Schwann, a zoologist , studied different types of animal cells and concluded that they are also composed of cells.
Schleiden and Schwann together gave the cell theory.
But a major drawback of this theory was that it could not explain how new cells are formed.
Rudolf Virchow, on careful analysis, observed that new cells are formed from pre-existing cells( Omnis cellula-e cellula).
Virchow gave the final shape to the cell theory based on the following points:
All living organisms are composed of cells and products of cells.
All cells arise from pre-existing cells.

Physiologic/pathologic conditions is most likely to result in an alkalosis, provided the body cannot fully compensate?
Repeated vomiting of stomach contents including HCl is most likely to result in an alkalosis in the given conditions.
Alkalosis is a condition which is characterized by the presence of excess amounts of base or alkali in the body fluids. It is just the opposite of a condition known as acidosis which is linked with the presence of excess acid.
Low levels of carbon dioxide as well as high concentration of bicarbonate in the body often leads to alkalosis. However, alkalosis can be of several types.
Metabolic alkalosis is generally caused due to accumulation of excess bicarbonate in the blood. It may also result from specific kidney disorders.

When organisms leave the group they were born into and join another group, this can alter allele frequencies in the new group. What mechanism is this?.
The answer to the question is gene flow.
What is gene flow?Gene flow, sometimes referred to as gene migration, geneflow, and allele flow in population genetics, is the exchange of genetic material between populations. A population can be deemed to be a single effective population if two populations have equal allele frequencies and the rate of gene flow is high enough. It has been demonstrated that all it takes is "one migrant each generation" to stop populations from drifting apart. Depending on how severe the selection pressure is, populations can diverge even when they are exchanging alleles. The exchange of genetic variety between populations is facilitated through gene flow. By altering allele frequencies, migrants affect how genetic variation is distributed among populations.

Names the retinal cells that communicate with ganglion cells, bipolar cells, and other cells that are similar to them.
What are retinal cells?
Light must travel through layers of neurons and capillaries before it reaches the photosensitive regions of the rods and cones in vertebrates because the light-sensing cells are located at the rear of the retina. The optic nerve must pass through the retina in order to reach the brain because the ganglion cells, whose axons make up the optic nerve, are located at the front of the retina. The blind spot results from the absence of photoreceptors in this area.

What is an important regulation process that connects various parts of a system?
Answer:
An important regulation process that connects various parts of a system is feedback.
Explanation:
A reaction inside a biological system—a molecule, tissue, species, or population—that affects the behavior or performance of that system is known as feedback. It essentially involves the regulation of a metabolic pathway by the activity's byproducts.
Both positive and negative feedback is possible. Negative feedback is indeed a component of any feedback mechanism that keeps things in balance. Positive feedback in biology occurs far less frequently. Whenever a change in variable results in a reaction that undoes the original change, this is known as negative feedback. A reaction is generated by a change in a factor when there is positive feedback. For instance, a warm-blooded species like a whale keeps a greater body heat to improve the internal equilibrium and while a cold-blooded animal such as fish retains a lower temperature of the body in accordance with the surrounding environment.

According to the question,
The number of mature seeds are formed in the fruit = 50 (Given)
The number of pollen grains land on a stigma = 100 (Given)
We know that, one male gamete will fuse with one egg nuclei to form zygote. In the double fertilization process, one gamete fuses with polar nuclei and forms endosperm. The other male gamete fuses with the egg to form zygote then it gives rise to seeds.
∴ 50 male gametes fuse with egg cells to form 50 seeds and other 50 male gametes fuse with 100 polar nuclei.
