Which of the following is the best definition of pseudoscience?

Answer:

The plots with no fertilizer

Explanation:

In an experiment, the control group is used as a comparison for the experimental group (the group being actively changed and observed).

So, in this experiment, the control group is the plots with no fertilizer.

This acts as a good control group because it provides a normal standard to show the effect of fertilizer on the tomato plants.

So, the control group in this experiment are the plots with no fertilizer.

Explanation:

Answer:

Whales and dolphins are mammals and have lungs instead of gills for breathing. They have blowholes at the tops of their heads that function like nostrils; they need to put their heads above water every so often to breathe. Both dolphins and whales have hair instead of scales, another quality that is specific to mammals. The animals have live births instead of laying eggs, and baby dolphins and whales nurse from their mothers. Whale and dolphin births take place near the surface of the water, so the young animals can easily take their first breath.

Both whales and dolphins rely on the sounds they make for survival, even though the sounds are utilized differently by each animal. For instance, whales make high-pitched groans and whistles to communicate with one another to warn against danger or navigate during migration

Answer:

COMPARISON AND CONTRAST OF WHALES AND DOLPHINS

Both dolphins and whales belong to the cetacean family and are marine animals that reside in the ocean. Some scientists even assert that dolphins are a type of whale, as the two animals have a number of shared characteristics. However, there are distinct differences between whales and dolphins as well that will teach you more about the physical appearance of these marine creatures and how they survive in their environment.

Esta teoría hace referencia al movimiento actual de las placas que sustentan los continentes y que se desplazan a lo largo de millones de años. En toda la historia geológica de la Tierra, los continentes no han estado siempre en la misma posición. Existe una serie de evidencias que veremos posteriormente que ayudaron a Wegener a refutar su teoría. El movimiento se debe a que continuamente está formándose nuevo material procedente del manto. Este material se crea en la corteza oceánica

Answer:

1:When a scientist repeats an experiment with a different group of people or a different batch of the same chemicals and get very similar results then those results are said to be reliable.Reliability is measured by a percentage if you get exactly the same results every

time then they are 100% reliable.

Viruses are not living cause they need any host (body or living organism) To perform its function.

Explanation:

Answer:

Viruses are not living things. Viruses are complicated assemblies of molecules, including proteins, nucleic acids, lipids, and carbohydrates, but on their own way they can do nothing until they entered a living cell. Without cells viruses will not be able to multiply. Therefore viruses ante not living things.

Human skin color is a good example of polygenic (multiple gene) inheritance. Assume that three "dominant" capital letter genes (A, B and C) control dark pigmentation because more melanin is produced. The "recessive"alleles of these three genes (a, b & c) control light pigmentation because lower amounts of melanin are produced.

Here, from the cross of the purple and white flower, all offspring are purple, which indicates that the purple color is dominant in nature and is present in Option A.

The Punnett square is a tool used to predict the probability of offspring inheriting specific alleles from their parents. If all of the offspring exhibit the same phenotype (such as purple flower color), it is likely that the parents both carried at least one dominant allele for that trait. This would mean that the purple flower color allele is dominant. Here, the parents are both purple and white, so all the offspring are dominant in nature.

Hence, from the cross of the purple and white flower, all offspring are purple, which indicates that the purple color is dominant in nature and is present in Option A.

Cloudlets, also known as altocumulus clouds, are tiny mid-level layers or patches of clouds that are most often seen as spherical clusters. Therefore, option (B) is correct.

Cloudlets, also known as altocumulus clouds, are tiny mid-level layers or patches of clouds that are most often seen as spherical clusters. However, since there are so many different types of altocumulus, they may take on a variety of forms.

Indicators of convection, or increasing heat, in the atmosphere include altocumulus clouds. Warm air rises into the sky, where it cools and condenses nearby water droplets to create the cloud formations that we see from the ground.

Answer:

The correct answer is d

Explanation:

Allosteric enzymes have multiple binding sites to different ligands called allosteric sites (different from the active site), these ligands can modify their kinetic properties. They are generally made up of more than one polypeptide chain, and have a quaternary structure, an enzyme with a quaternary structure can bind more than one substrate molecule. An allosteric enzyme is an enzyme whose activity is regulated by an allosteric center, which is a site, other than the active center of the enzyme, to which a regulator (called an allosteric regulator) binds in a reversible and non-covalent manner. The binding of this regulator modifies the three-dimensional structure of the enzyme and affects the configuration of the active site, thus increasing or decreasing its activity, depending on the case. The allosteric sites present in regulatory enzymes is where allosteric effectors or inhibitors are attached, causing a conformational change in the substrate binding site or catalytic site, thus regulating enzyme activity.

Answer:

d. depends on changes in their quaternary structure on binding of substrates or inhibitors

Explanation:

Allosteric enzymes are oligomeric proteins composed of subunits or polypeptidic chains. They have a quaternary structure -many subunits and active sites- and express two states, R and T. Both states establish an equilibrium, with or without a joint ligand.

When the transition from one state to the other occurs, symmetry is conserved, but the affinity of a site to a ligand is altered. When a substrate joins one of the sites, it affects other binding sites.

Allosteric enzymes can change their conformation, exhibiting active and inactive conformations as a result of substrate binding at the activated center and regulatory molecules at other binding sites -allosteric centers-.
