Which is the greatest threat to survival of large predator species, like mountain lions and tigers
A) loss of other predator species
B) Global climate changes
C) loss of large wilderness areas
D) animal diseases
Answers
Answer:
B) Global climate changes
Explanation:
The greatest threat to the survival of large predator animals such as mountain lions and tigers is the change occurs in climate. Due to climate change, the temperature of the whole world increases. On mountains, the temperature is very low which is favorable for the growth of mountain lions and tiger. But increase occurs in the temperature of these mountain areas due to global warming, these animals die.
B) Global climate changes
Climate change has produced a number of threats to wildlife throughout our parks. Rising temperatures, lower many species survival rates due to changes that lead to less food, less successful reproduction, and interfering with the environment for native wildlife.For example, as temperatures get warmer, many plants are starting to grow and bloom earlier in the spring and survive longer into the fall. Some animals are waking from hibernation sooner or migrating at different times, too.Therefore, correct option is B.

Explanation:
A mutation that inserts or deletes one or two nucleotides is usually more harmful than a mutation that substitutes one base for another because -
A It changes one amino acid in the sequence of a protein
B it shifts the reading frame for the rest of the code causing many errors
C The codon consists of three nucleotides coding for an amino acid
D the chromosomes fail to separate resulting in trisomy 21
Answers
If one or two nucleotides are added or deleted, they will cause a shift in the reading frame. This resulted in many errors.
Frame Shift Mutation:
There is code for every amino acid consecutively present in mRNA. These codes are read by the ribosome to form proteins. If one or two nucleotides are deleted or inserted, It completely changes the patern of codes. Hence it will read differently and form a non-functioning protein.Hence, we can conclude that If one or two nucleotides are added or deleted they will cause a shift in change the reading frame result in many errors.

An uncovered pot of water lies out in the sun. Which statements correctly describe what happens at the surface of the liquid water?
Answers
When an uncovered pot of water lies in the sun, the water undergoes evaporation and potentially reaches a point of equilibrium with condensation when the air is saturated. Water's high surface tension and ice's lower density than liquid water play pivotal roles in Earth's ecosystems.
An uncovered pot of water lying in the sun undergoes several changes on the surface due to energy from the sun. Initially, as the water absorbs heat, it will begin to evaporate, turning from liquid into water vapor. This process decreases the water level in the pot. Over time, the rate of evaporation will be balanced by the rate of condensation, which is when water vapor turns back into liquid water. This balance is achieved when the air above the water becomes saturated with water vapor.
Furthermore, liquid water possesses a high surface tension, which helps it to form droplets and adhere to surfaces. This property, in combination with capillary action, is essential for the upward transport of water in plants and soil. As for solid water, or ice, its lower density compared to liquid water means that it floats, an important factor in the survival of aquatic organisms in cold climates.
The water cycle is demonstrated as a continuous open system in which water gains and losses occur. Water is gained from the outgassing of the earth's crust, while losses happen when hydrogen from water molecules in the gaseous state escapes the earth's gravity and is lost to space due to the energy from sunlight.
In an ecosystem, organisms compete for different resources. Intraspecific competition occurs when there’s competition for resources between members of the same species. What do you think the word interspecific refers to? Give an example with your explanation.
Answers
Answer:
Interspecific competition refers to competition between members of different species. For example, several species of flowering plants compete to attract pollinating insects, such as bees, for successful reproduction.
Explanation:
answer from Plato
The ecosystem is defined as the geographic region, in which plants, animals, and other organisms work together to live and survive.
In an ecosystem, intraspecific and interspecific competition is seen for food, shelter, and habitat.
Intraspecific competition is defined as the competition between organisms belonging to the same species. The organism fight for shelter and food.
Interspecific competition is defined as the rivalry or competition in organisms of different species living in the same ecosystem.
For example, the competition between woodpeckers and squirrels is a type of interspecific competition. Both the organisms fight for shelter and create holes in the trees.
Thus, intraspecific refer to the rivalry among organisms of the same species, whereas the competition between the organisms of different species in an ecosystem is interspecific.

contrast the chromosome number in gametes and zygotes in sexual reproduction into your answer in the space provided
Answers
Answer:
Chromosome number in gametes- haploid (n)
Chromosome number in zygote- diploid (2n)
Explanation:
Sexually-reproducing organisms make use of gametes to reproduce. The gametes are produced via the process of meiosis, which is a cell division that results in daughter cells (gametes) that have their chromosomal number reduced by half. A diploid (2n) organism i.e. possess two set of chromosomes undergoes meiosis to produce haploid (n) gametes i.e. contains one set of chromosomes. The male parent produces haploid sperm while the female parent produces haploid egg.
During reproduction, these haploid gametes (sperm and egg) combine in a process called FERTILIZATION to produce a diploid ZYGOTE. The diploid zygote then divides and grows into the full organism. Hence, since a zygote is formed by the fusion of two haploid gametes (sperm and egg), it contains a diploid chromosome number i.e. sperm (n) + egg (n) = zygote (2n)

What is the inheritance pattern in which
| both alleles are expressed?
Answers
Answer:Codominance, as in human blood type, is a form of inheritance in which both alleles are expressed equally in the phenotype of the heterozygote.
Explanation:
The inheritance pattern where both alleles are expressed is known as codominance, distinct from Mendelian inheritance, with human blood type AB being a classic example.
The inheritance pattern in which both alleles are expressed is called codominance. In this genetic scenario, unlike the Mendelian dominance-recessive relationships, both alleles contribute to the offspring's phenotype. An example of codominance is seen in human blood types, where both A and B alleles are expressed, resulting in AB blood type.
Another form of non-Mendelian inheritance is incomplete dominance, where the phenotype is intermediate between the two parents, like wavy hair resulting from one curly hair allele and one straight hair allele. However, these should not be confused with dominant lethal inheritance patterns, which result in an allele being lethal both in the homozygote and the heterozygote. Dominant lethal alleles can only be transmitted if the lethality phenotype occurs after reproductive age.

What is the term for traits evolved by organisms to help them survive more easily in their climate and biome
Answers
explanation: organisms evolve adaptations that help them survive in the climate of the biome where they live.
The term you are referring to is "adaptive traits" or "adaptive characteristics." Adaptive traits are specific features or characteristics that have evolved in organisms over time to help them better survive and thrive in their particular climate and biome.
These traits are the result of natural selection, a fundamental mechanism of evolution, where individuals with advantageous traits have a higher chance of surviving and reproducing, passing these traits on to their offspring.
Adaptive traits can take various forms, such as physical adaptations (e.g., camouflage, insulation, or specialized appendages for feeding), physiological adaptations (e.g., efficient temperature regulation mechanisms), or behavioral adaptations (e.g., migration patterns or foraging strategies). The key to their success is their compatibility with the specific environmental conditions of a given biome, enabling organisms to exploit available resources and cope with challenges, like extreme temperatures, food scarcity, or predation.
Ultimately, adaptive traits play a crucial role in shaping the diversity of life on Earth and are essential for an organism's survival and reproduction within its specific habitat.

Smallpox is a virus that causes a rash that then turns into painful blisters. The last known case of smallpox was in 1977. smallpox was eradicated when a vaccine was developed against it.
What is smallpox?The variola virus (smallpox virus) first appeared thousands of years ago and began causing illness and death in human communities, with smallpox epidemics occurring on a regular basis.
How was smallpox eradicated by the vaccine?The first successful vaccination was Edward Jenner's smallpox vaccine, which was launched in 1796. He discovered that milkmaids who had previously contracted cowpox were immune to smallpox, and that injected vaccinia protected against inoculated variola virus.Jenner scratched fluid from a cowpox blister into the skin of an eight-year-old boy named James Phipps. James had a single blister on the location, but he recovered quickly. Jenner inoculated the boy with smallpox particles again on July 1, but no sickness developed.

The best explanation for smallpox eradication is the development of an effective vaccine, not increased exercise, genetic testing, or antibacterial products.
The smallpox vaccine, created by Edward Jenner in the late 18th century, was a groundbreaking medical advancement that played a pivotal role in eliminating the disease.
Unlike the other options provided, the success in combatting smallpox was not due to increased exercise, genetic testing, or an uptick in antibacterial products.
Exercise, while beneficial for overall health, is not a direct factor in smallpox eradication.
Genetic testing, though crucial for understanding susceptibility to certain diseases, wasn't the primary strategy for smallpox control.
Similarly, an increase in antibacterial products doesn't address the viral nature of smallpox.
The global smallpox eradication campaign, led by the World Health Organization (WHO), involved mass vaccination efforts and targeted interventions.
The vaccine's efficacy led to the interruption of transmission chains, ultimately resulting in the last known case in 1977.
The comprehensive vaccination strategy and international collaboration demonstrate the significant impact a well-developed vaccine can have in eradicating a deadly infectious disease, marking smallpox as the first human disease to be eradicated through intentional efforts.

Ventricles pump blood out of the heart. Which types of vessels will be the first to contact the blood from the ventricles?
arteries
atria
capillaries
veins
Answers
Ventricles pump blood out of the heart, and the types of vessels that will be the first to contact the blood from the ventricles are arteries. This is the first option, as after the ventricles contract, blood is pumped out of the heart through the pulmonary artery.
What is the heart and ventricles ?The heart has four chambers: two atria (upper chambers) and two ventricles (lower chambers). Blood flows into the atria from the veins and then flows into the ventricles. The right ventricle pumps blood to the lungs through the pulmonary artery, while the left ventricle pumps oxygen-rich blood to the rest of the body through the aorta.
Arteries are blood vessels that carry blood away from the heart. They are thick-walled and muscular, with elastic fibers that allow them to withstand the high pressure generated by the pumping action of the heart. Arteries branch out into smaller arteries and arterioles, which eventually lead to capillaries.
Hence, the ventricles pump blood out of the heart, and the types of vessels that will be the first to contact the blood from the ventricles are arteries. This is the first option.

What is a blood group?A person will still have type A blood even if they inherit both the A and O alleles. Blood type is genetically determined by the genotypes, or allele compositions, of the parents.
Three different allele types—A, B, and O—make up the ABO gene. The first two, A and B, are codominant, which means they each have an equal amount of dominance, allele O, however, is recessive.
The numerous blood types are created by various combinations of these three alleles, which can be the A, B, AB, and O blood group of John.
