what are some reasons implicit stereotypes might differ from explicit stereotypes?

Answers

Answer:

Implicit stereotypes are automatically activated and operate indirectly, and thus individuals may not be aware that they possess such beliefs. In contrast, explicit stereotypes are accessible to conscious awareness and are what individuals report when asked about group differences.

Explanation:

Please rate, thank me, have a good day

Implicit stereotypes operate automatically and indirectly, so people may not realize they have them. When asked about group differences, people report explicit stereotypes.

What are stereotypes?

A stereotype is a preconceived notion or combination of traits that many people hold to be indicative of a certain kind of person or object. Stereotypes are traits that society automatically ascribes to particular groups of people in order to categorize them according to factors like age, weight, occupation, skin tone, gender, etc.

Since implicit stereotypes function subtly and automatically, people may not even be aware that they hold such beliefs. Conversely, explicit stereotypes are cognizable and are what people report when questioned about group differences.

that is the answer

Photosynthesis is the process by which energy stored in inorganic molecules is used to produce carbohydrate food molecules.

What is photosynthesis?

Photosynthesis is the primary process by which plants, algae, and some bacteria capture and store energy from the sun.

During photosynthesis, light energy is absorbed by pigment molecules in the chloroplasts of plant cells. This energy is then used to convert carbon dioxide (CO2) and water (H2O) into glucose (C6H12O6) and oxygen (O2). The glucose produced during photosynthesis is used by the plant as a source of energy and is also stored as a carbohydrate reserve. The oxygen produced during photosynthesis is released into the atmosphere as a byproduct.

A change in pH has the greatest impact on which life proces

Answers

Answer:

Aquatic Organisms

If the pH of water is too high or too low, the aquatic organisms living within it will die. pH can also affect the solubility and toxicity of chemicals and heavy metals in the water ¹². The majority of aquatic creatures prefer a pH range of 6.5-9.0, though some can live in water with pH levels outside of this range.

Explanation:

Adding more OH- ions increases the pH, making the substance more basic. Increasing the pH will increase the number of OH- ions, so the equilibrium will shift to the left. Decreasing the pH will increase the number of H3 O+ ions; they'll ''use up'' the OH- ions, thus shifting the equilibrium to the right.

How does thermal energy impact the lower layers of atmosphere?

Answers

Answer:

Explanation:

Land and water absorb most of the solar radiation from the sun. Some of this solar energy from land and water is then transferred to the lower atmosphere which is in contact with the continents and oceans. From Land, this occurs mostly as heat energy or infrared radiation. Water usually transfers this energy through the evaporation of water into the atmosphere

Organize these rock layer from youngest to oldest
Breccia

Conglomerate

Dolostone

Shale

Answers

Conglomerate,Shale,Dolostone

From youngest to oldest are Breccia, Conglomerate, Dolostone, and Shale, and as per geology, the principle of superposition states that in a sequence of layered rocks, the youngest layer is on top and the oldest layer is at the bottom.

What are rock layers?

Breccia is the youngest layer in the sequence. Breccia is a coarse-grained sedimentary rock made up of angular fragments of other rocks that have been cemented together. It is formed through a process called brecciation. Conglomerate is also a coarse-grained sedimentary rock, but unlike breccia, its fragments are rounded and well-worn, indicating that they have been transported over a distance by water or wind before being deposited and cemented, and dolostone is older than both breccia and conglomerate. Shale is the oldest layer in the sequence.

Hence,    From youngest to oldest are Breccia, Conglomerate, Dolostone, and Shale.

which high grade, foliated metamorphic rock has visible crystals?

Answers

Answer:

Gneiss

Explanation:

Gneiss forms at the highest pressures and temperatures and has crystals large enough to see with the unaided eye. Gneiss features minerals that have separated into bands of different colors. The bands of colors are what define foliation within gneiss.

Hope this helps! : )

Gneiss crystals are large enough to be seen without magnification. Gneiss has color-banded minerals. Color bands define gneiss foliation.

What is Gneiss?

The metamorphic rock known as gneiss is quite common and can be found all over the world. It is produced when procedures of high temperature and high pressure metamorphism are applied to formations that are made up of rocks that are either igneous or sedimentary in nature.

Gneiss is formed at temperatures and pressures that are higher than those required to make schist. Gneiss almost always has a banded texture that is defined by alternating darker and lighter colored bands and does not have a clear cleavage. Gneiss may also lack a distinct cleavage.

Gneisses are frequently found in the crust of continental shields that formed in the distant past. Gneisses like the Acasta Gneiss are among the oldest rocks on Earth and are classified as Proterozoic.

when two strains of bacteria with genotypes abcd and abcd are grown together in the lab, a small number of bacteria with the genotype abcd eventually arise. how does this likely occur?

Answers

Answer:

These enzymes work in two ways. Some are pre-replicative and search the DNA for nucleotides with unusual structures

Explanation:

This happened through a lateral transfer of genes.

We can arrive at this answer because:

Lateral gene transfer is a system for exchanging genetic material between unrelated bacteria.Bacteria are beings that reproduce without the exchange of genetic material, but in some cases, this can be done with the lateral transmission of genes.This transmission can be done through the process of conjugation, translation, or transformation.

The result is that new bacteria are created with a mixture of genes from two unrelated bacteria.

which muscle group relates best with the term midline?

Answers

The oblique is the muscle group that best relates with the term midline.

The anterolateral abdominal wall contains a muscle group in which there are flat muscles whose fibers originate in the posterolateral part, pass forward and become an aponeurosis towards the midline:

The external oblique muscle is the thickest and most superficial of the three muscles on the lateral wall of the abdomen.

It follows an inferomedial direction and the muscle-tendon limit descends in such a way that, towards the midline and also below the height of the anterior superior iliac spine, it is completely transformed into an aponeurosis.

The aponeurosis of the external oblique joins that of the internal oblique and passes in front of the rectus abdominis; its fibers intersect in the midline with those on the opposite side and contribute to the linea alba.

Therefore, we can conclude that the oblique is the muscle group that best relates with the term midline.
