Answer:

The mitochondrial gene tree suggests a later split because it occurred hybridization later in time, with the transference of the brown bear mitochondrial genetic information to the polar bear population. So the mitochondrial gene tree exhibits a later divergence.

Because the first divergence event of the common ancestor occurred 60,000 years ago, evidenced by nuclear DNI and mitochondrial DNI. However, 100,000 years ago, concerning the mitochondrial genetic material, the hybridization event defined a new more recent common ancestor between the two species.

Explanation:

The use of mitochondrial DNA might present a few problems that need to be considered in evolution studies. It involves only one locus, so it has some limitations when reconstructing history, especially if the locus went through any process, such as natural selection, bottleneck events, or its transference to another population due to hybridization. There is also a high possibility of an incomplete reconstruction of the population history if males and females have different dispersal patterns.

The most proper way of reconstructing history is by complementing mitochondrial information with nuclear genetic information and evaluating their concordancies.

In the exposed example, 600,000 years ago, the original species split into the polar bear and the brown bear. But 100,000 years ago, hybridization occurred between a brown bear female and a polar bear male. The offspring joined the polar bear population, carrying the female genetic information, nuclear and mitochondrial. With time, these individuals interbred with the polar bears, diluting the nuclear brown bear genetic information. However, females carrying the brown bear mitochondrial DNI seemed to be more successful reproductively than the polar bear females. The mitochondrial information, hence, has been in the population for many generations, until today. And this information came from a more recent common ancestor, compared with nuclear genetic information.

Answer: Plants that always produce the same traits as their parents when they are self pollinated

Mendel used self-pollination in pea plants to grow true-breeding plants for his experiments. When a true-breeding plant self-pollinates, its offspring all have the same traits as the parent. For example, a true-breeding plant with purple flowers always has offspring with purple flowers.

Answer:

I have never seen this question before but my best guess is B.

Explanation:

Answer:

Verdadero

Explanation:

Sabemos que los caracteres dependen de los genes. Y los genes pueden presentarse en forma de alelos dominantes, o alelos recesivos. La expresión de los alelos recesivos son enmascarados o escondidos por el alelo dominante. Es decir, que si ambos alelos se encuentran juntos en un heterocigota, solo el alelo dominante se expresará.

Entonces el alelo dominante expresa la característica que resulta dominante, mientras que el alelo recesivo expresa la característica recesiva.

Genotipo:

Por ejemplo, si tenemos dos fenotipos rojo y amarillo, y sabemos que el color esta codificado por un gen dialelico llamado M. También supongamos que no sabemos qué alelo expresa qué color. Teniendo solo estos datos, no podemos decir si el rojo es el color dominante o si el amarillo lo es.

Sin embargo, si tenemos los siguientes genotipos acompañando esta información:

Recién ahora podemos deducir que el caracter dominante es el amarillo.

Giraffes are well known for their unusual height, and they generally feed high in the tree canopy, above the height other herbivores can reach. ... Therefore, the researchers argue, it is competition from other herbivores, such as kudu, that appears to drive giraffes to eat leaves high in the trees.

Since plant roots require water and oxygen (from the air in pore spaces), maintaining the balance between root and aeration and soil water availability is a critical aspect of managing crop plants.

Answer:

sperm and the hormone testosterone.

Explanation:

Sperms and hormone testosterone are produced by Testes.

A testicle, which is pronounced "teh-stuh-kl," is a component of the anatomy of men and those who are born male . You typically have two testicles. These organs produce hormones and sperm.

Male gonads or testes (pronounced "teh-steez") are other names for your testicles. A testis is a single testicle.

The temperature of your testicles is roughly two degrees Celsius lower than the rest of your body. Spermatogenesis, the production of sperm, benefits from cooler temperatures.

Therefore, Sperms and hormone testosterone are produced by Testes.

Aaron may not  have a phobic disorder if he had his first pain attack on his first at a new high school.

A phobia is an uncontrollable, irrational, and lasting fear of a certain object, situation, or activity. This fear can be so overwhelming that a person may go to great lengths to avoid the source of this fear. One response can be a panic attack. This is a sudden, intense fear that lasts for several minutes.

It is not compulsary that aaron have phobic disorder if he had his first panic attack on his first day at a new high school because he already faced middle school.

Explanation:

Wegener is not qualified to propose theories in the fields of geology and the history of the Earth because there was no mechanism available to endorse his proposals and offer a convincing and truthful explanation, hence the rejection of the Continental Drift, the theory that made him famous.

The north pole has been known as the northernmost point present on earth, and on the other hand south pole has been known as the southernmost part or the point of the earth. The area present in  between south pole and north pole has been said that it has been extremely cold and the area present near the equator has extremely hot.

The area of north pole has not the part of any country or the north pole does not lie in any country. The main reason of the coldness of the north pole and south pole has that they do not receive any direct sunlight. The best time to visit the north pole has the time of June and July because in this month the ice of the north pole is thinner as compared to other months.

Therefore, Wegener is not qualified to propose theories in the fields of geology and the history of the Earth because there was no mechanism available to endorse his proposals and offer a convincing and truthful explanation, hence the rejection of the Continental Drift, the theory that made him famous.

Explanation:

To review meaning are both prereading and postreading strategies used.

Before attentively reading a text (or a chapter of a text) from beginning to end, pre-reading is the process of scanning the material to identify essential concepts. sometimes known as surveying or previewing.

Pre-reading gives you an overview, which can help you read more quickly and effectively. Examining (and considering) chapter titles, summaries, headings, subheadings, study questions, and conclusions are typical pre-reading activities.

Students can use pre-reading tactics to anticipate what they will read or hear by considering what they already know about a particular topic. Teachers can focus on a book's organization, teach new vocabulary or other concepts, look for the primary idea, and provide students a reason for reading or listening before they even begin to read any material.
