The dynamic equilibrium of your internal environment termed negative feedback mechanism true or false?

Answer:

The correct answer is - small intestine; glucagon, glycogen; glycerol, sodium bicarbonate; starch, iron, plasma, hemoglobin; fats.

Explanation:

The digestive enzymes are released in the small intestine by pancreatic cell, the cluster of these pancreatic exocrine cells called pancreatic islets that release insulin and glucagon hormones for controlling blood sugar level.

Insulin stores the excess amount of blood glucose in the liver as glycogen and in the case of low sugar glycerol is converted to glucose from fats. Pancreatic juice contains sodium bicarbonate to regulate acidity and the amylase enzyme helps in digesting starch. The liver stores various nutritional substances such as vitamins and iron and others and release them in blood plasma.

Answer:

Whey protein.

These proteins help you gain strength, and healthy fats.

Organisms in Bacteria, Archaea, and Eukarya each have adenine, thymine, guanine, and cytosine bases forming their DNA provides evidence that best supports common ancestry for organisms in all three domains.

C is the correct option.

Cell division suggests that a process exists that duplicates DNA and provides identical copies for the daughter cells while preserving an accurate picture of the genome. Genetic inheritance is made possible by the DNA replication mechanism, which is present in all living things.

One old template strand and one freshly generated strand make up each of the two DNA molecules produced by the replication process, which is semi-conservative. It serves as the foundation for how genetic information is expressed through protein synthesis. Given that DNA replication happens quickly, there are a number of ways to assure accurate replication and reduce mistakes. DNA replication mistakes or mutations can lead to cancer.

An adaptation is a heritable change in behavior or morphology that increases fitness. This means that the trait can be passed down through generations and helps organisms better survive and reproduce in their environment.

An adaptation is a heritable change in behavior or morphology that increases fitness, meaning it improves an organism's ability to survive and reproduce in its environment. This change can be the result of natural selection, where advantageous traits are favored and passed on to future generations, or genetic drift, where random changes in a population's gene pool occur due to chance events. Adaptations can also contribute to reproductive isolation, as they may prevent individuals from different populations or species from successfully interbreeding.

Based on the given options, the best phrase to describe these two chromosomes based on their genetic content is: sister chromatids of the same chromosome number.

Sister chromatids are identical copies of a single chromosome that are produced during DNA replication. They are held together at a region called the centromere. Sister chromatids are connected to each other until they separate during cell division.

During cell division, sister chromatids are pulled apart and distributed to daughter cells, ensuring that each daughter cell receives a complete set of chromosomes. Once separated, the sister chromatids become individual chromosomes.

The term "same chromosome number" indicates that the two sister chromatids belong to the same chromosome, meaning they contain the same genetic information. The chromosome number refers to the specific type of chromosome within a species.

It's important to note that homologous pairs of chromosomes also exist in diploid organisms, but they are not applicable to the given scenario. Homologous chromosomes are pairs of chromosomes that have similar genetic content but are not identical. They come from each parent and contain corresponding genes in the same order. Homologous chromosomes pair during meiosis and undergo genetic recombination.

Completely separate chromosome number would refer to distinct and unrelated chromosomes, which is not the case for sister chromatids.

The correct answer is (b) Yes because the proton pump will generate a proton gradient that ATP synthase can use to synthesize ATP for two proteins into the membrane of artificial lipid vesicles.

The light-activated proton pump from Halobacterium halobium will use energy from light to transport protons across the membrane and create a proton gradient. The ATP synthase will use the energy from the proton gradient to synthesize ATP from ADP and Pi.

The electron-transport chain is unnecessary for this system to produce ATP since the energy for proton transport comes from light instead of electron transport.

The fact that the proteins come from different organisms is not a limiting factor since they can still function together in the artificial lipid vesicles.

Spindle fibers are structures in cells that play a critical role in cell division. During cell division, spindle fibers help separate the chromosomes in the cell's nucleus into two equal sets, which then go into separate daughter cells.

The spindle fibers attach to the chromosomes and use their dynamic movement to ensure that each daughter cell receives an equal set of chromosomes.

The spindle fibers are made up of microtubules, which are long, thin, tube-like structures that form the underlying scaffold of the spindle. In addition to their role in cell division, spindle fibers also help organize the shape and structure of cells.

Arteries have thicker walls compared to veins because arteries need to withstand higher blood pressure and maintain their shape while carrying oxygenated blood away from the heart.

Arteries and veins are two types of blood vessels in the circulatory system with distinct functions. Arteries carry oxygenated blood away from the heart to various tissues and organs. To fulfill their role, arteries have thicker walls compared to veins. The thicker arterial walls serve several purposes. Firstly, arteries experience higher blood pressure due to the forceful pumping action of the heart. Thicker walls help arteries withstand this pressure without bulging or rupturing. Secondly, the muscular layer (smooth muscle) within arterial walls allows them to constrict or dilate, controlling blood flow to different areas of the body. Additionally, the elastic fibers in the arterial walls allow them to expand during systole (contraction phase of the heart) and recoil during diastole (relaxation phase), maintaining a continuous flow of blood. In contrast, veins carry deoxygenated blood back to the heart under lower pressure, so their walls are thinner and less muscular.

Answer: Autotroph, producer

Explanation: The grass gets eaten by primary consumer starting the food chain

In a food chain, the grass is referred to as an autotroph and producer. Therefore, option D is correct.

An organism is referred to as an autotroph or primary producer when it uses carbon from simple substances like carbon dioxide to create complex organic compounds. These creatures often obtain their energy from inorganic chemical reactions or light.

Both plants like blue-green algae and microorganisms like cyanobacteria are assumed to be autotrophs. Most plants are autotrophs because they create their own food through photosynthesis. But there are always exceptions to the norm. Some plants are parasitic and non-photosynthetic, getting their nutrition from a host.
