Answer:
Social issues such as poverty and to fulfill basic needs etc.
Explanation:
Social issues such as poverty, lack of awareness and to fulfill basic needs etc affected the problem or its solution in the stories i.e. "Using forests wisely" and "Community conservation" because these issues forced people to cut the forest and use the lands unwisely to fulfill their basic needs and betters their social status in the society. Due to poverty, people cut the trees in the forest and sold them to earn money in order to buy food and other necessary items for their family. If these social issues are solved, there is no need for cutting of trees and land use.

how do lizards regulate body temperature in winter?
Answer:
Lizards are experts in thermoregulation and are able to maintain an ideal body temperature most of the time. Lizards hibernate in winter if the weather is too cold for them to reach the required body temperature.
Explanation:
reptiles regulate their body temperature through what is called thermoregulating . simply put this means basking in a warm area to heat up and moving to a cool are to cool down ..... reptiles hibernate in winter if the weather is too cold for them to reach the required they body temparature
Why does the mitochondrial gene tree suggest a later split? Why the disparity between the nuclear gene tree?
this is the link: https://learn.genetics.utah.edu/content/evolution/bears/
Answer:
Why does the mitochondrial gene tree suggest a later split?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.
Why the disparity between the nuclear gene tree?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.
Why are both prereading and postreading strategies used?
O to review meaning
O to increase reading speed
O to enhance comprehension
O to memorize text
Answer:
A. to review meaning
Explanation:
To review meaning are both prereading and postreading strategies used.
What is Prereading?
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.
Therefore, To review meaning are both prereading and postreading strategies used.

Answer:
sperm and the hormone testosterone.
Explanation:
Sperms and hormone testosterone are produced by Testes.
What is 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.

Verdadero o falso mediante el genotipo podemos determinar si existen dominancia en una característica
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:
Homocigota dominante ----> Expresa caracter dominante (Solo el alelo dominante esta presente)Heterocigota -------------------> Expresa el caracter dominante (Ambos alelos estan presentes, pero el dominante es quien se expresa)Homocigota recesivo --------> Expresa el caracter recesivo (solo alelos recesivos estan presentes)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:
MM--> AmarilloMm--> Amarillomm --> RojoRecién ahora podemos deducir que el caracter dominante es el amarillo.
