Explanation:

On the 28th day of embryonic development, the human brain resembles a hollow tube. This stage is called the neural tube stage, which is a critical period in the formation of the nervous system.

During this stage, the neural plate folds in on itself, forming the neural tube, which will eventually become the brain and spinal cord. The walls of the neural tube differentiate into different regions, and the ventricular system, which contains cerebrospinal fluid, begins to form. This is also the stage when the neural crest cells begin to migrate and differentiate into various cell types, including sensory neurons, autonomic neurons, and glial cells. The neural tube stage is crucial for the proper formation of the nervous system, and any disruptions during this period can lead to serious congenital defects such as spina bifida or anencephaly.

In the structure of epithelium, the cells are arranged in a regular fashion, either in a single layer or stacked one upon another to form many layers. Whereas in the connective tissues, the arrangement of the cells depends upon the location of the tissue, the cells are arranged irregularly. They can be either loosely packed or densely packed.

Since the function of epithelium is to form the outer layer of the skin or form the lining of organs, therefore the cells are arranged in a regular fashion to completely cover the organ they are present in.

Connective tissues have the function of supporting the other tissues or organs. For this the cells are arranged in an irregular haphazard manner so that they support the organ as well as remain light-weighed.

Answer: The recycling of. NAD+ allows glycolysis to continue. The products of this process are two molecules of an alcohol, often ethyl alcohol, two molecules of carbon dioxide, and two molecules of NAD+. Just like lactic acid fermentation, alcoholic fermentation recycles NAD+ and so allows glycolysis to keep making ATP.

Answer:

A primary role for the glucose molecule is to act as a source of energy; a fuel.

Explanation:

Plants and animals use glucose as a soluble, easily distributed form of chemical energy which can be 'burnt' in the cytoplasm and mitochondria to release carbon dioxide, water and energy.

Answer:

It is a source of energy.

Explanation:

Plants and animals use glucose as a source of fuel and is a source of energy in a cell function. It also generates energy that the Human cells use to carry metabolic and  biological function.

The ecologist was comparing the a) density of white-tailed deer between the two woodlots.

Density is a measurement of the number of individuals per unit area or volume, and in this case, it is calculated as the number of white-tailed deer per square kilometer.

Density is an important ecological measurement because it can provide insights into population dynamics, such as growth, reproduction, and mortality rates. It can also help determine if a habitat can support a population of a particular species. In this case, the ecologist recorded twelve white-tailed deer per square kilometer in one woodlot and twenty per square kilometer in another.

The ecologist was not comparing dispersion, which refers to the spatial distribution of individuals within a population, carrying capacity, which is the maximum number of individuals that a habitat can support, or range, which refers to the geographical area over which a particular species occurs.

Therefore, option (a) is correct.

The link between various organisms in an ecosystem is depicted graphically by an ecological pyramid. It displays the movement of energy throughout the various trophic levels of an ecosystem.

Three or four trophic levels make up the majority of food chains. Typical sequences include plant, herbivore, carnivore, and top carnivore; alternatively, plant, herbivore, parasite of the herbivore, and parasite of the parasite may be used.

Various trophic levels are followed by producers at the base of ecological pyramids (such as herbivores that eat plants, then carnivores that eat flesh, then omnivores that eat both plants and flesh, and so on). The top of the food chain is the most elevated position.

Explanation:

Bacterial cells are very small - about 10 times smaller than most plant and animal cells. Most bacterial cells range in size from 0.2 to 10 microns or micrometers (0.0000079 to 0.00039 inches). ... One reason why bacterial cells are so small is that they need a large surface area to cell volume to take in nutrients.

The products of one process are the reactants of the other. Notice that the equation for cellular respiration is the direct opposite of photosynthesis: Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O. Photosynthesis: 6CO2 + 6H2O → C6H12O6+ 6O.

Explanation:

Answer:

Due to mixing of particles present in the upper layer of limestone with sandstone during deposition.

Explanation:

The parent layer was limestone layer which is older than sandstone layer. This sandstone layer spreads on the limestone layer because of wind. The wind moves these sandstone from other region and their deposition occurs on the limestone layer. During deposition of sandstone, some particles of limestone which are present at the surface mixes with the sandstone so that's why in sandstone layer, small and weathered pieces of limestone are present.

Scientists isolate cells in various phases of the cell cycle. They find a group of cells that have 1.5 times more DNA than G1 phase cells. The cells of this group are in the S phase of the cell cycle.

The cell cycle is a series of events that occur within a cell as it grows and divides. Cells spend the majority of their time in interphase, where they develop, duplicate chromosomes, and develop for cell division. Cells then exit interphase, proceed through mitosis, and divide completely.

The S phase (synthetic phase) is the phase of the cell cycle during which DNA is replicated and occurs between the G1 and G2 phases. Since accurate replication of the genome is critical for successful cell division, the processes occurring during S phase are tightly regulated and largely conserved.

In S phase, the cell synthesizes a complete copy of DNA in the nucleus. It also replicates microtubule-organizing structures called centrosomes.
