neutrons.
C. Methane gas combines with oxygen to form carbon dioxide and
water.
O D. Two isotopes of hydrogen fuse to form helium.
SUBMIT
Answer:
C
Explanation:
Because its a chemical reaction or whatever but it's correct
A reaction where the atoms of elements are rearranged is when two isotopes of hydrogen fuse to form helium, which is option D. In this reaction, the atoms of elements (hydrogen isotopes) are rearranged.
The fusion process involves the combination of two hydrogen isotopes, typically deuterium and tritium, to form a helium nucleus. This nuclear fusion reaction is the primary process that powers stars, including our Sun, where hydrogen atoms combine to form helium, releasing a tremendous amount of energy in the process. Deuterium is an isotope of hydrogen that contains one proton and one neutron, while tritium is another isotope of hydrogen that contains one proton and two neutrons.

Natural selection involves energetic trade-offs between ________. Group of answer choices high survival rates of offspring and the cost of parental care increasing the number of individuals produced during each reproductive episode and a corresponding decrease in parental care producing large numbers of gametes when employing internal fertilization versus fewer numbers of gametes when employing external fertilization choosing how many offspring to produce over the course of a lifetime and how long to live Next
Answer:
The correct answer is ''high survival rates of offspring and the cost of parental care''
Explanation:
Natural selection is the differential reproduction of some genetic variants with respect to others. Natural selection favors individuals who maximize their total reproductive success throughout life, that is, it favors certain phenotypes or variants are associated with greater offspring and / or greater survival, that also means that selection will favor those who stop spending on a particular breed at the right time to invest in another, that is, the amount of energy invested in each of them. This same natural selection also favors those genes that make it effective when the body that carries them is in development to extract all possible parental investment from their parents.
Calculate the gravitational potential energy of a 1,200 kg car at the top of a hill that is 42 m high.
Answer:
Gravitational potential energy = 493,920 J
Explanation:
Given:
Mass of car = 1,200 kg
Height = 42 m
Find:
Gravitational potential energy
Computation:
We know that;
Gravitational acceleration g = 9.8 m/s²
Gravitational potential energy = mgh
Gravitational potential energy = (1,200)(9.8)(42)
Gravitational potential energy = (11,760)(42)
Gravitational potential energy = 493,920 J

Scientists are examining the possible role of a large asteroid in the Cretaceous mass extinction event. A large asteroid strike would likely have caused rapid climate cooling and diffusion of sunlight.
Which of the following statements are the best null and alternative hypotheses when scientists look at the geologic evidence of extinction related to the asteroid strike?
A) Null: The rate of extinction would be steady over the entire length of time the climate was altered.
Alternative: The rate of extinction would be greatest immediately before the asteroid strike.
B) Null: The rate of extinction would gradually decrease over the entire length of time the climate was altered.
Alternative: The rate of extinction would be at its lowest immediately after the asteroid strike.
C) Null: The rate of extinction would be steady over the entire length of time the climate was altered.
Alternative: The rate of extinction would be greatest immediately after the asteroid strike.
D) Null: The rate of extinction would gradually decrease over the entire length of time the climate was altered.
Alternative: The rate of extinction would be at its greatest immediately after the asteroid strike.
Answer:
Option C
Explanation:
The null hypothesis is the problem statement and alternative hypothesis is counter of the null hypothesis.
Hence, the null hypothesis here is the rate of extinction was neither higher nor lower when there were sudden climatic changes (asteroid strike)
And alternate hypothesis is "the rate of extinction was either higher or lower when there were sudden climatic changes (asteroid strike)"
Hence, option C is correct

explain how limiting factor may affect your terrarium
Answer:
A limiting factor is anything that constrains a population's size and slows or stops it from growing. Some examples of limiting factors are biotic, like food, mates, and competition with other organisms for resources. Others are abiotic, like space, temperature, altitude, and amount of sunlight available in an environment. Limiting factors are usually expressed as a lack of a particular resource. For example, if there are not enough prey animals in a forest to feed a large population of predators, then food becomes a limiting factor. Likewise, if there is not enough space in a pond for a large number of fish, then space becomes a limiting factor. There can be many different limiting factors at work in a single habitat, and the same limiting factors can affect the populations of both plant and animal species. Ultimately, limiting factors determine a habitat's carrying capacity, which is the maximum size of the population it can support.

Thanks Hope it helps.Name at least two ways in which insects are beneficial to humans.
Answer:
Natural and biological control :
The balance of nature depends on the activities of parasites and predators, the majority of which are species of insects. Researchers use this concept in biological control, and have been dramatically successful in many programs.
Silk :
The recognition of silk as a valuable product dates back to China, arguably in the year 2640 B.C. Presently, China annually produces some 30,000 tons of raw silk, which accounts for 80 percent of the world's supply. Most silk is produced from the cocoons of the Silkworm.

Chicken pox is a virus that causes an itchy rash but typically does not have any major or lasting effects on an infected person. Before 1995, chicken pox parties were popular. In a chicken pox party, healthy children were brought around children who were ill with chickenpox so that they would be exposed to the virus and their immune system would learn to fight it. A vaccine for chickenpox was developed in 1995, and chicken pox parties are now rare.

La interacción entre soluto y solvente que permite que se forme una disolución se denomina solvatación
Answer:
Verdadero.
Explanation:
En una solución hay un solvente y uno a más solutos. El solvente es el componente que se encuentra en mayor cantidad y que disolverá al soluto. El soluto es el componente que se encuentra en menor cantidad y que se disolverá en el solvente. Para que se forme la disolución, los iones o moléculas presentes en el soluto tienen que ser rodeados por moléculas provenientes del solvente, este proceso se llama solvatación.

Differentiate between dominance and co-dominance.
Answer:
Dominance is when only 1 type of dominant allele is expressed. Incomplete dominance is when 2 different types of recessive alleles are received. This means neither trait is expressed, but a mixture of both traits are expressed (e.g. white and black horse have grey offspring) because both are recessive, so one cannot mask the other.

In pea plants, the allele for smooth pods (S) is dominant over the allele for constricted pods (s).
Which of the following pairs of terms are correctly matched?
Choose 1 answer:
Ss - phenotype; smooth pod - genotype
SS - genotype; constricted pod - phenotype
SS - phenotype; constricted pod - genotype.
SS - genotype; constricted pod - phenotype
Answer:
ss - genotype; constricted pod - phenotype
Explanation:
trust me Lol
Pea plants having gene control phenotype of pod shape S is dominant having phenotype smooth and phenotype constricted pods having s genotype, hence option d is correct.
What is the difference between genotype and phenotype?Phenotype is a physical observation of a trait which control by agene
and genotype is a genetic observation that can not be seen physically.
The allele which controls the phenotypic character of a plant is called the dominant over the other allele which can not show its expression, the allele is always present in a group but only the dominant will show its expression.
In a pea plant, if the allele for smooth is dominant over the other, it shows expression in allelic combination and masks the expression of constricted pods.
Therefore SS is the genotype and the constricted pod is the
phenotype, hence option d is correct.

How does biological evolution work?
Answer: It uses natural selection to choose traits that are more favorable which is measured by if the species can make fertile offspring. For example horses can make fertile offspring like donkeys can also do this but a cross betweek male donkeys and female horses can make offspring(mule) but not fertile ones. Fertile offsprings are offsprings/ kids that can have kids.

Disorders can occur as a result of a person missing chromosomes or having too many chromosomes. Which of the following cells would not have a disorder?
sex cell with 24 chromosomes: 22 autosomes and two sex chromosomes
sex cell with 23 chromosomes: 22 autosomes and one sex chromosome
sex cell with 24 chromosomes: 23 autosomes and one sex chromosome
sex cell with 22 chromosomes: 22 autosomes and no sex chromosomes
Answer:
sex cells with 23 chromosomes: 22 autosomes and one sex chromosome.
Explanation:
Sex cells are the gametes and are products of meiosis. These cells have haploid chromosome number. Human sex cells are sperms and egg which serve as male and female gamete respectively. Human sex cells have n = 23 chromosomes. Out of total 23 chromosomes, 22 chromosomes are autosomes while one is the sex chromosome (either X or Y chromosome). Deviation from this pattern can cause any genetic disorder.
