Answer: Mendel considered traits hidden in the first generation to be recessive.

Explanation: Recessive traits, in order to be expressed in an organism's phenotype (physical characteristics) must be homozygous. This means that in a monohybrid cross, which means a trait with only one gene, (E.g. Aa, aa, AA) in order for a recessive gene to be expressed it must be combined with itself. (Examples include aa, bb, cc,)

The 10 metals you would not use would be "Lithium (Li),Sodium (Na), Potassium (K), rubidium (Rb), Cesium (Cs), Francio (Fr)", "Beryllium (Be), Magnesium (Mg), Calcium (Ca), Strontium (Mr), Barium (Ba) and Radio (Ra)" due to their low melting temperature.

Refractory metals are a class of metals that are remarkably resistant to heat and wear. The expression is most often used in the context of materials science, metallurgy and engineering. The definition of which elements belong to this group may vary. The most common definition includes five elements: two from the fifth period (niobium and molybdenum) and three from the sixth period (tantalum, tungsten and rhenium). They all share some properties, including a melting point above 2000 °C and high hardness at room temperature. They are chemically inert and have a relatively higher density. Their high melting points make powder metallurgy the method of choice for manufacturing components from these metals. Some of its applications include tools for machining metals at high temperatures, filament yarn, casting molds, and chemical reaction vessels in corrosive environments. In part due to the high melting point, refractory metals are stable against creep deformation at very high temperatures.

Answer:

D

Explanation:

Because fossil fuels are inexpensive to produce, and distribute. It's not A because fossil fuels are harmful to the environment. Not B because it's not reusable. And it's not C because it won't make the world warm enought for life.

The positive point is that this type of farm reduces the proliferation of antibiotic-resistant bacteria. The negative point is that this makes cultivation difficult, which can make the product more expensive and lead to the sale of dishonest products.

We can arrive at this answer because:

In this case, the changes that lead to the cessation of the use of tylosin are beneficial, as they reduce the proliferation of resistant bacteria. On the other hand, there is a major expense to promote the growth of cattle, which will make the meat more expensive.

In addition, the lack of inspection can promote dishonest products, as it causes some producers to use antibiotics to promote livestock growth, but sell these products like natural products.

Diversity is the first word out of Darwin's mouth at the end of his research travels.

How does evolution explain diversity?

The interactions between organisms and environment and the consequence of interactions over long periods of time explains duversity and evolution.

Darwin discovered the natural selection that explains the development of variety of organisms from a single common ancestor. The change in the environment provides a high variability of alleles that helps in evolving the new environment.

What is the Darwin's theory of evolution?

The process by which change in organisms due to the change in behavioral and physical traits.

Due to the change in environment individuals develop adaptive traits in order to survive and reproduce. These adaptive traits are advantageous to the upcoming population.

Darwin proposed that species change over time and new species come from pre-existing species sharing a common ancestor.

Hence, Darwin discovered diversity at the end of his research travels.

Explanation:

Actin filaments (also known as microfilaments), microtubules, and intermediate filaments make up the cytoskeleton's three primary structural elements.

They each have a unique structural makeup and perform somewhat different but related roles.

Microfilaments, cytoskeleton, and gap junctions make up the cytoplasm of a cell. These elements aid in the organisation of the cell's components and give the cell its form. They serve as a foundation for cell division and mobility as well.

Three main kinds of protein components make up the cytoskeleton. The microfilaments (actin filaments), intermediate filaments, and microtubules are arranged from narrowest to broadest. Myosin is frequently related to microfilaments.

Actin monomers make up microfilaments, whereas intermediate filaments are made up of intermediate filament protein subunits. Microtubules are composed of beta and gamma tubulin dimers.

Explanation:

Living in the Communication Age grants us extensive access to information, but it also exposes us to the risk of information overload, which encompasses the negative emotions associated with receiving an overwhelming amount of information.

Information overload occurs when individuals are bombarded with an excessive amount of information, often surpassing their capacity to process and absorb it effectively. In the Communication Age, the internet, social media, and various digital platforms provide a constant influx of data and news, leading to the potential for information overload.

The consequences of information overload include feelings of overwhelm, stress, and anxiety. When individuals are exposed to an overwhelming amount of information, they may struggle to filter and prioritize relevant content, resulting in a sense of being buried under an ever-growing pile of data. Moreover, information overload can lead to decision paralysis, as individuals may find it challenging to make informed choices amidst a sea of conflicting or contradictory information. The cognitive overload caused by excessive information can impair concentration, decrease productivity, and negatively impact overall well-being. Thus, while access to abundant information has its advantages, it is crucial to manage and filter the flow of information to avoid the detrimental effects of information overload.

Explanation:

The amount of glucose in the blood is regulated by the negative feedback mechanism.

When the glucose level in the blood increased beyond the normal level, the pancreas secretes insulin which converts the excess glucose to glycogen. Glycogen is stored in the liver and the muscles.

When a person has not eaten for a while and the glcose level drops beyond normal, glycogen is converted back to glucose and released into the blood by another enzyme produced by the pancreas, glucagon.
