1) One reason why deforestation is occuring because people need wood from trees to build things, therefore, leading them to cuting countless of trees.
2) One environmental problem that results from widespread deforestation is that the carbon dioxide they would normally use remains in the atmosphere, therefore, promoting erosion.
3) One way to lessen the effects of deforestation is by re-planting the cut-down trees and by cutting down less trees.

Interactions between organisms and their environment impact the organism’s overall population. The jaguar Panthera onca is the largest cat in North America. It is found in areas across the Southwest, including Arizona, New Mexico, and Texas. It is a carnivore that has powerful jaws and sharp teeth and preys on fish, turtles, tapirs, and many smaller mammals. Which shows the relationship between the jaguar and turtles?
A. Adaptation principle
B. Competitive exclusion principle
C. Predator-prey relationship
D. Niche principle
The correct answer is C. Predator-prey relationship
Explanation:
In a prey-predator relationship, one organism which is the predator feeds on another animal known as the prey. Additionally, predators hunt and kill their prey, which is essential for predators to obtain nutrients and survive. Besides this, predators can hunt and feed on only one type of animal or hunt and feed on different types of animals. This relationship occurs between the jaguar and the turtle because the jaguar hunts, kills, and eats the turtles, which means jaguars hunt and kill other animals to get nutrients. Also, in the case of the jaguar, this hunts different animals including fish, tapirs, turtles, and small mammals.

The resource competition model of sympatric speciation requires: A. divergent/disruptive selection driving character displacement. B. directional selection driving character displacement. C. evolution of reproductive isolation D. Both A & C E. Both B & C
Answers
Answer:
The correct answer is option D, that is, both disruptive selection and evolution of reproductive isolation.
Explanation:
The phenomenon of the evolution of a novel species from a thriving ancestral species and at the same time both continue to live in a similar geographical area is termed as sympatric speciation. Due to reproductive isolation of the population of species that were thriving in a similar habitat, the phenomenon of sympatric speciation results.
On the other hand, sympatric speciation also results due to disruptive selection as in the process the extreme kind of individuals within the population are favored over the hybrids.

which of the following represents a testcross
A- t? x tt
B- XX x XY
C-T? x Tt
D- T? x TT
Answers
Answer:
The option should be like this:
A- T? x tt
Explanation:
In an inheritance pattern in which a particular allele is exhibiting doiminance over the other, the dominant phenotype can either be homozygous or heterozygous. Hence, it is impossible to tell the genotype of a dominant phenotype by merely observing it. A cross called TEST CROSS is used.
A test cross is a cross used to determine the actual genotype of a dominant phenotype i.e. whether it is homozygous or heterozygous by crossing tye unknown genotype with a homozygous recessive parent. If all of the offspring of this cross have a dominant phenotype, it means the dominant parent is HOMOZOGOUS but if offsprings with an equal ratio of dominant and recessive phenotypes are produced, it means the dominant parent is HETEROZYGOUS.
In this case, the dominant phenotype whose genotype is unknown is (T*) while the recessive parent will be (tt).

Under certain circumstances, potassium ions ( K+K+ ) in a cell will move across the cell membrane from the inside to the outside. The potential inside the cell is −70.5 mV−70.5 mV and the potential outside the cell is zero. What is the change in the electrical potential energy of a single potassium ion as it moves across the membrane?
Answers
Answer:
the change in the electrical potential energy of a single potassium ion as it moves across the membrane is 1.12941 × 10⁻²⁰ J
Explanation:
The formula used in determining the change in the electrical potential energy can be expressed by the relation.
Charge in electrical Potential energy = [tex]q ( V_2 - V_1)[/tex]
where q = the potassium ion
q = 18 electrons and 19 protons
q = 19-18 = 1 electron
1 electron = 1.602 × 10⁻¹⁹ Coulombs
Thus;
the potential inside the cell is −70.5 mV
= -70.5 × 10⁻³ V
∴ Charge in electrical Potential energy = [tex]q ( V_2 - V_1)[/tex]
Charge in electrical Potential energy = [tex]1.602*10^{-19} ( 0 - (-70.5*10^{-3})[/tex]
Charge in electrical Potential energy = 1.12941 × 10⁻²⁰ J
Thus; the change in the electrical potential energy of a single potassium ion as it moves across the membrane is 1.12941 × 10⁻²⁰ J
what features of meiosis are important in sexual reproduction
Answers
Answer:
The daughter cells are identical to the mother cell in shape and size but different in chromosome number. The daughter cells are haploid. Recombination and segregation take place in meiosis. The process occurs in the reproductive organs and results in the formation of gametes.
Explanation:
During sexual reproduction, meiosis generates genetic variation in offspring because the process randomly shuffles genes across chromosomes and then randomly separates half of those chromosomes into each gamete. The two gametes then randomly fuse to form a new organism.
alapogos tortoises have a number of shell variations, shown right. What are the advantages of choosing a system examining the beaks of finches instead of the shells of tortoises? Check all that apply. Birds have shorter lifespans, making generations shorter. The bird population is likely much greater, allowing for more data. Tortoises move too slowly for natural selection to influence shell phenotype. Birds are easier to track and monitor.
Answers
The question lacks essential part that is options to answer, however the options are given:
1. Birds have shorter lifespans, making generations shorter.
2. The bird population is likely much greater, allowing for more data.
3. Tortoises move too slowly for natural selection to influence shell phenotype.
4. Birds are easier to track and monitor.
Answer:
The correct options are : 1, 2, and 4.
Explanation:
For the accuracy and dependability of any experiment, various observations must be as extensive as possible. It decreases the impact of any observation or any event which may have occurred by some coincidence or mistake.
Therefore, finches were smarter to record observation as they were accessible in enormous numbers when compared with the turtle.
Likewise, the life cycle of birds is less when contrasted with the turtle which empowered the researchers to observe more generations.
In conclusion, the birds were anything but difficult to catch and track when contrasted with the turtle. Turtle is a land and water proficient which made it hard to follow them.

A farmer is raising rabbits. The average body weight in his population is 3kg. The farmer selects the 10 largest rabbits in the population, whose average body weight is 4kg, and interbreeds them. If the heritability of body weight in the rabbit population is 0.7, what is the expected body weight among the offspring of the selected rabbits?
Answers
Answer:
The expected weight increase that is expected of offspring of selected parents is 0.7 kg
Explanation:
Given from the question:
The average body weight in his population of rabbits = 3 kg
heritability of body weight in the rabbit population (h^2)=0.7
Average body weight of the 10 selected largest rabbit =4 kg
(R) = response to selection
selection differential (S)= Average body weight of the 10 selected largest rabbit - The average body weight in his population of rabbits
selection differential (S)= 4-3=1 kg
But heritability of body weight in the rabbit population (h^2)=0.7
Then, Heritability of body weight in the rabbit population (h^2) can be calculated using the formula below;
Heritability of body weight in the rabbit population (h^2)=
response to selection (R) / selection differential (S)
response to selection (R) = Heritability of body weight in the rabbit population (h^2) × selection differential (S)
R= h^2 x S= 0.7 x 1kg= 0.7 kg
The expected weight increase that is expected of offspring of selected parents is 0.7 kg
Average weight of offspring = The average body weight in his population of rabbits + heritability of body weight in the rabbit population (h^2)
Average weight of offspring= 3 kg + 0.7 kg = 3.7kg
Therefore, the Average weight of offspring is 3.7kg and The expected weight increase that is expected of offspring of selected parents is 0.7 kg
during drought years on the galapagos,small easily eaten seeds become rare, leaving mostly large, hard-cased seeds that only birds with large beaks can eat. if drought continues for several years, measurable changes to the beak size of the galapagos bird population can be observed. which of the following identifies the changes to the beak size of the galapagos bird population what would most likely be expected as a result of natural selection? a) more small-beaked birds dying than larger beaked birds. the offspring produced in later generations have a higher percentage of birds with large beaks. b) small birds gaining larger beaks by exercising their mouth parts c) small birds mutating their beak genes resulting in later-generation offspring having larger beaks d) small birds anticipating the long drought and eating more to gain weight, resulting in them growing larger beaks
Answers
Answer:
A) More small-beaked birds dying than larger beaked birds
Explanation:
Natural selection will cause the small-beaked birds to die, while large-beaked birds will begin producing more birds with that gene. This causes large-beaked birds to become dominant, and less and less small-beaked birds will survive.
Hope this helps!
Answer:
A.
Explanation:
Considering that the seeds have changed to where larger birds can only consume them (or birds with larger beaks, anyways..) then smaller beaked birds would die or as a result of the changing in the food supply.If the food supply revolves around having a stronger or larger beak, then birds with larger beaks are more likely to flourish.
