Answer:

This question lacks options, the options are:

A) FF and ff

B) FF and Ff

C) Ff and Ff

D) Ff and ff

The answer is D (Ff and ff for parent 1 and 2 respectively)

Explanation:

This question depicts a single gene coding for fur colour in mice. The gene controls two traits, black fur and white fur, encoded by alleles F and f respectively.

According to the question, a pair of mice has been bred several times to generate the same data of 22 black fur and 23 white fur mice. Based on this data, it shows that the phenotypic ratio of black to white mice is 1:1.

To get a 1:1 phenotypic ratio of black fur offspring to white fur offspring, the parents mice must have genotypes Ff (heterozygous) and ff (same recessive alleles).

In a cross between parents Ff × ff (see punnet square), offsprings with the following genotypes will be produced: Ff, Ff, ff and ff. Ff is black furred while ff is white furred.

Ff (2) : ff (2) is equivalent to Ff (1) : ff (1).

Hence, a data of 22 black mice and 23 white mice which represents a 1:1 ratio will only be produced by parents mice with genotypes: Ff and ff.

Answer:

secondary succession happens more often because it occurs after some kind of distribution that still leaves the soil intact (mudslide,bulldozing,shoveling,or scraping off an area)

Explanation:

Answer:

Secondary succession

Explanation:

Succession may be defined as the change in the biological species community with time. Primary succession and secondary succession are two main types of succession.

Secondary succession is the succession that occurs most often in nature because this succession occurs when the climax community is disturbed by the natural and man made disturbances. The secondary succession has almost every thing to start the new succession again in the destroyed land.\

Thus, the correct answer is secondary succession.

Answer:

A. necklace

Explanation:

Necklace  is most likely made from both metals and gemstones.

A necklace might be a straightforward chain made of gold or silver, a string of beads or diamonds, or a pendant suspended from a rope. It qualifies as a necklace as long as it is worn around the neck.

Unless you are a professional or amateur geologist—or perhaps you earned a merit badge studying them as a scout—you probably won't be able to explain the differences between these four hard natural materials: minerals, rocks, gemstones, and crystals.

The different types of necklace are chocker, Matinee and opera. Long and functional, opera length necklaces. The necklace should hang below the bust when worn as a single strand.

Therefore, Necklace  is most likely made from both metals and gemstones.

Answer: XHXh (Note: the H's are superscripts.)

Explanation:

Hemophilia is a sex-linked recessive trait which means that the males having one altered copy of the gene is enough to cause the medical condition( as they have only one X chromosomes and females have two)

In this case the genotype of father and son is such that they are affected by hemophilia.The son has mother's X chromosome and father's Y chromosome.

XhY is the genotype of father and son. As mother would be heterozygous because she is not affected, her genotype will be XHXh.

Explanation:

The primary and Secondary structure are essential and present in all proteins and also include tertiary.

The primary structure is the amino acid sequence of the protein. This is the basic part of the protein.

The secondary structure are local folded structures that form within a polypeptide as a result of a couple of interactions between atoms of the backbone giving rise to the alpha helix and the beta pleated sheets in protein structures.

Answer:

Deuteromycotes

Explanation:

Kingdom Fungi consist of eukaryotic organisms grouped into 3 phyla, with one group that doesn't fit into any of the grouped three. Each group of fungi were classified into phylum based on their reproductive life cycle. The three phyla are Zygomycotes, Ascomycotes, Basidiomycotes.

Zygomycotes produce their spores by meiosis in a structure called Zygosporangium. Ascomycotes produce their spores via meiosis in ascus (sac-like). Basidiomycotes produce their own spores via meiosis in club-like basidium.

However, a fourth group exists that has no known sexual reproductive structure (meiospores), instead it is known to reproduce asexually via mitospores. This group is called DEUTEROMYCOTES or commonly known as FUNGI IMPERFECTI. It is a group of miscellaneous fungi that doesn't fit into the classification basis of the other three phyla.

CIERTO.

Explicación:

Este es un ejemplo de adaptaciones conductuales conocidas como adaptaciones anti-depredadoras. Esto es principalmente importante en áreas donde hay poca vegetación. Los búhos de madriguera, las tortugas que viven en los desiertos y las suricatas son ejemplos. Estos animales se encuentran en regiones de baja vegetación. Por lo tanto, no están protegidos de los depredadores. Por lo tanto, cavan profundo bajo tierra para escapar del depredador.

Además, debido a que estas regiones son principalmente áridas, los animales necesitan escapar de la alta temperatura y, por lo tanto, conservar el agua.

Answer:

"theory of evolution by natural selection,”

this was proposed by charles darwin and alfred wallace in the 19th century

The ecological effects of acid rain are most clearly seen in aquatic environments, such as streams, lakes, and marshes where it can be harmful to fish and other wildlife. As it flows through the soil, acidic rain water can leach aluminum from soil clay particles and then flow into streams and lakes. The more acid that is introduced to the ecosystem, the more aluminum is released, die of biodiversity in environment and other organism that supports decomposition of material

Answer:

Explanation:

Circular and yellow seeds are overwhelming and wrinkled and green seeds are passive. It is vital to keep in mind that resective characteristics are as it were displayed when the sibling has two passive alleles for those characteristic, in the event that the descendant includes a latent allele and a overwhelming allele, the characteristic that will be presented is the overwhelming one. For this reason, able to say that a cross between RRYY x RrYy plants, would not create any descendant with wrinkled and yellow seeds. Typically since, the descendant of a crossing, must show an allele of each parent. One parent as it were has overwhelming alleles (RRYY), so able to say that all descendant will get 1 overwhelming allele for color and a overwhelming allele for seed surface, anticipating the sibling from communicating latent characteristics.

Answer:

The correct answer is Tectonic plate movement is a long-term environmental change.

Explanation:

When tectonic plates in the earth started to move, this process helped the planet to evolve and to shape the continents as exist today.

Different investigation teams have discovered that plates move approximately 2.5 centimeters per year. This movement is the key to the evolution of life and the development of the planet. This slow process involves mountain formation, rocks exposure, and chemical reactions that could stabilize the temperature on the earth´s surface for millions of years. And this stable weather is essential for the evolution of life. Plates movement carries carbon inside and outside of the planet, regulating the amount of carbon dioxide in the atmosphere (greenhouse effect). In this way, it can regulate the temperature. This regulation influence in precipitations,  chemical reactions that involve carbon release and minerals such as calcium, the water flow, volcanic eruptions, among other events. Plates tectonic is also responsible for life, as weathering and mineralization of the rocks release elements and nutrients that are necessary for the life of different organisms.    

So, up to this point, we can say that tectonic plates movement can not be prevented with planning, it does cause environmental change by regulating temperature, and hence it affects organisms.

There are short term effects and long term effects provoked by tectonic plates movement. Earthquakes are examples of short term effects, while mountain formation, ocean formation and, clime regulation are examples of long term changes.

Plates tectonic movement is a very slow process, that might last many years. The Andes formation, for example, started approximately 200 years ago, and these mountains are still rising. The subduction process has not finished as the plates are still moving.

Answer:

Choice A

Explanation: This is because the main purpose of the cell cycle is to create new cells for the organism via mitosis or meiosis.

The cell cycle illustrates the procedures, which occurs as a cell produces new cells.

It refers to a series of events, which occurs in a cell as it grows and differentiates.

A cell devotes majority of its time in the phase known as interphase, and during this time it develops, divides its chromosomes, and prepares for the division.

After that the cell leaves interphase, and goes through the process of mitosis, and completes the process of division.

It can be said that the prime task of cell division is to produce novel cells.

Thus, the correct answer is option A, that is, forms new cells.
