The correct answer is option D

The population of rabbit over the first unit of time is reduced because the population of snakes was more than the normal population.

The predators of rabbits are snakes and if the population of predator will be more than the population of the rabbit then snakes will eat them. Ultimately the population of rabbit will be decreased.

Then after some time the population of rabbit increased as the population of snakes decreased.

The rabbit population to decrease because A higher than normal population of snakes. Option D

Due to the fact that there were more snakes than usual during the first unit of time, the rabbit population decreased.

Snakes are the rabbits' main predators, and if there are more snakes than there are rabbits, the snakes will consume the rabbits. The rabbit population will eventually decline. Following that, as the population of snakes declined, the population of rabbit rose.

Non-scientific method:

Well, an easy way is observing the filament under a microscope: if it contains one cell it's unicellular and if it contains more than one cell it's multicellular.

Scientific method:

Filamentous algae are, in principle, single-celled. But, sometimes they can form colonies and evolve to be multicellular. But still, if they just form a colony they'll still be unicellular until they start changing.  

Answer:

Unicellular.

You can only make one zygote but in some cases the egg splits and makes an identical twin.

Final answer:

A couple can potentially produce over 64 trillion unique zygotes due to the combination of meiotic genetic recombination, random fertilization, and occasional occurrences of twins, both dizygotic and monozygotic.

Explanation:

The number of unique zygotes that a couple can produce is astonishingly high due to the genetic variability involved in sexual reproduction. Each human zygote contains a unique set of 46 chromosomes, with 23 inherited from each parent. This genetic diversity arises from the process of meiosis during gamete formation, where chromosomes are shuffled and recombined. Additionally, random fertilization further increases genetic variability.

While most often a single egg is released and fertilized, resulting in a unique zygote for each pregnancy, there are cases such as dizygotic twins where two eggs are released and fertilized by two different sperm, resulting in two genetically distinct zygotes. Furthermore, unique scenarios can lead to monozygotic twins, where a single zygote divides to form genetically identical offspring. However, when considering the number of potential unique children a couple can produce without considering twins, the estimated number of genetically unique zygotes is over 64 trillion, showcasing the vast potential for genetic diversity.

Explanation:

Bohr Model: In this model negatively charged electrons orbits a positively charged nucleus like the planets orbiting around the sun. Coulomb force between the negatively charged electrons and positively charged nucleus is mathematically akin to the gravitational force of the solar system. Important points are-

Bohr Model of Hydrogen :

The example of hydrogen atom is simplest in case of Bohr model or for a hydrogen-like ion in which the electrons which is negatively charged orbits around a positively charged nucleus. Only certain electron orbits are allowed and radius of the orbit increases square of n, where n is the principal quantum number. The first line of Balmer series is produced in the 3 to 2  transition. For hydrogen, z=1, this produces a photon of wavelength 656 nanometer.

Final answer:

The statement is false; dye molecules continue to move randomly even after diffusing evenly throughout the water due to constant kinetic energy.

Explanation:

The statement that 'after a dye diffuses uniformly throughout a glass of water, the dye molecules are no longer moving' is false. Diffusion is the process by which molecules move from an area of high concentration to an area of lower concentration. When you place a drop of dye into water, it will diffuse until there is an even distribution throughout the water. This state is known as equilibrium, where there is no net movement of dye molecules, but the individual dye molecules continue to move randomly. It's important to note that molecular motion is constant due to kinetic energy, so even when the dye has spread out evenly, the molecules are still in motion.

The streams and rivers in the drainage basins were the prairies are converted into farm land are mostly affected by the agriculture and its needs, as well as its consequences.

The agriculture demands water for irrigation, and most of this water comes from  the streams and rivers, so that contributes to lowering of the water levels of the streams and rivers.

The agriculture also causes damage to the streams and rivers by polluting them. Namely, the pesticides, herbicides, and fungicides that are used for protection of the plants, partially end up in the low groundwater's, and in general, these waters are connected to the streams and rivers, so the pollutants end up in them, and that affects the biodiversity in them very badly.

Explanation:

Answer: Option C

Explanation:

The energy that is required by the body is primarily stored in the form carbohydrates. The energy from the carbohydrates is easily converted into a usable form which is adenosine triphosphate.

The energy from the carbohydrates can be derived easily but from lipids it is difficult. Lipids contain more energy than carbohydrates because they contain more carbon to hydrogen bonds and when these bonds are broken down they release energy.

This energy is much more than carbohydrates. Hence, the maximum energy in the molecules is in lipids.

is there any other info?

The correct answer is D. The results only support her hypothesis. I just answered this question on study island and this is the correct answer.

Answer: B. Amount of matter produced by the producers should be more than that of the consumers.

Food web defines a interconnection between different food chains and transfer of energy at each trophic level. According to the ten percent law 10% energy is lost from each trophic level. At the first trophic  level there are producers. Producers occupy the only one level in the trophic levels the rest is occupied by consumers this shows the category of consumer is more than producer. Therefore, for successful food web food availability should be more at initial trophic level hence amount of matter produced by the producers should be more than that of the consumer.

Amount of matter produced by the producers should be more than that of the consumers because matter and energy are lost with each successive step of the food chain. Therefore, for a food web to be functional and successful, the total amount matter produced by the producers be more than that of the consumers they support.

The right option is; C. Inherited mutations exist in all cells in the body and somatic mutations only exist in the cell type that mutated.

Inherited mutations are gene mutations that exist in almost every cell in the body throughout an individual’s life. Inherited mutations are inherited from a parent and can also be transmitted. They are also called germline mutations because they exist in the parent’s egg or sperm cells (gametes).

Somatic mutations are gene mutations that exist in only certain cell types that are mutated, not in every cell in the body and it take place at some time during an individual’s life. Somatic mutations are not inherited and cannot be passed. They are caused due to environmental factors (such as cigarette smoke or ultraviolet (UV) radiation) or due to error during DNA replication.
