reason:

Life process

Explanation

Earthworms

Movement

All living things move in some way. This may be obvious, such as animals that are able to walk, or less obvious, such as plants that have parts that move to track the movement of the sun.

Earthworms use circular and longitudinal muscles to move through soil or along surfaces.

Respiration

Respiration is a chemical reaction that happens within cells to release energy from food.

The food that earthworms eat supplies their body with energy-rich molecules such as glucose. On entering the cells of their body, these molecules are broken down in a series of steps to release energy to be used by the body, producing carbon dioxide and water as waste products.

Sensitivity

The ability to detect changes in the surrounding environment.

Earthworms have light-sensitive cells scattered in their outer skin. Their skin cells are also sensitive to touch and chemicals.

Growth

All living things grow.

Earthworms hatch from eggs and can grow up to a metre or more in length! Some earthworms are also able to regrow small parts of their body that have been lost or injured.

Reproduction

The ability to reproduce and pass genetic information onto their offspring.

Earthworms have both sperm and eggs within their bodies (they are hermaphrodites) but they cannot self-fertilise and need to mate with another individual. After mating, a cocoon containing the fertilised eggs is deposited in the soil.

Excretion

Getting rid of waste.

Earthworms excrete waste from their anus – the last segment of their body.

Nutrition

The intake and use of nutrients. This occurs in very different ways in different kinds of living things.

Earthworm nutrition comes from a variety of sources, depending on their species. Food types include manure, compost, plant material, fungi, microorganisms and decaying animals. They take in food through their mouths.

Answer:

Map distance = Genetic distance, GD = 3.9 MU ≅ 4 MU

Explanation:

The more separated two genes are, the more chances of recombination there will be.  The closer they are, the fewer chances of recombination there will be. Two genes that are very close will have a few recombination events and are strongly bounded.    

To analyze the recombination frequency, we have to know that:

The map unit is the distance between the pair of genes for which every 100 meiotic products one of them results in a recombinant one.  

Knowing that the genes are linked, we can calculate genetic distances between them. First, we need to identify the genotypes of the parental gametes with the ones of the recombinants. We can recognize the parental gametes in the descendants because their phenotypes are the most frequent, while the recombinants are the less frequent. So:

Parentals:

Recombinants:

To calculate the recombination frequency we will make use of the next formula: P = Recombinant number / Total of individuals.

P = Recombinant number / Total of individuals.  

P = 17 + 12 / 337 + 364 + 17 + 12

P = 29 / 730

P = 0.039

The genetic distance (GD) will result from multiplying that recombination frequency (P) by 100 and expressing it in map units (MU).

GD = P x 100

GD = 0.039 x 100

GD = 3.9 MU ≅ 4 MU

Answer:

cloning is the right answer

Through Recombinant DNA scientists can artificially change the DNA code of organisms.

Recombinant DNA is a term used to describe the process of creating new combinations of DNA from different sources. This is done by cutting DNA molecules from different sources and joining them together, creating a recombinant molecule.

This process is often used in biotechnology for applications such as creating new vaccines, improving crop yields, and producing therapeutic proteins. Recombinant DNA technology plays a crucial role in many areas of modern biology and medicine, including genetic engineering, gene therapy, and drug discovery.

The parietal lobes are primarily responsible for receiving and processing sensory input such as touch, pressure, heat, cold, and pain. The parietal lobes are also involved in the perception of body awareness and the construction of a spatial coordinate system (mental map) to represent the world around us

Answer:

The parietal lobe is one of the four major lobes of the cerebral cortex in the brain of mammals. The parietal lobe is positioned above the temporal lobe and behind the frontal lobe and central sulcus. ... The name comes from the parietal bone, which is named from the Latin paries-, meaning "wall".

Explanation:

hope this helps!

The rabbit population will consist of 35% white rabbits and 65% brown rabbits.

Until a limiting factor, such as low reproduction, food scarcity, predation, disease, and/or weather conditions restrict populations, the population tends to grow.

Some density-dependent limiting factors are the spread of pathogens, competition for nesting locations, the destruction of habitat, increase in the population of predators. Several predators, including raptors and coyotes, use rabbits as food, but in urban and suburban areas, cats and dogs pose the biggest threat. Some abiotic limiting factors are drought, flood, earthquake, and all types of natural disasters.

Thus, the rabbit population will consist of 35% white rabbits and 65% brown rabbits.

The city's water supply shortage seems to be the result of a combination of physical, social, and political factors. Well below-average rainfall patterns, the increasing unpredictability of weather conditions due to anthropogenic climate change impacts, population growth, and government mismanagement have produced one of the worst urban water crises in recent memory.

here is the reason your explanation from the water shortage now just figure out what the factors are in your answers I would say it's naturally occurring drought conditions because it says on here well below average rainfall patterns and climate change

Water shortage can occur as a result of mismanagement practices by humans or as a result of natural occurrences such as droughts.

Water shortage refers to a situation in which there is not enough water to meet the daily water needs of the human, animal and plant population in a particular area.

The hydrogen bond is responsible for many of the anomalous physical and chemical properties of compounds of N, O, and F. In particular, intermolecular hydrogen bonding is responsible for the high boiling point of water (100 °C) compared to the other group 16 hydrides that have much weakerhydrogen bonds

Explanation:

Hydrogen bonding is primarily responsible for the high boiling point of the water. Thus, the correct option is B.

Hydrogen bonding is an interaction which involves a hydrogen atom that is located between a pair of other atoms such as nitrogen, oxygen, and fluorine which have a high affinity for electrons, and such a bond is weaker than an ionic bond or a covalent bond but are stronger than van der Waals forces and dispersion forces.

Hydrogen bonding is primarily responsible for the high boiling point of water solvent. Hydrogen bonding is a strong affinity. Hydrogen bonding is created when a hydrogen atom is bonded to an electronegative atom by approaching a nearby electronegative atom.

Therefore, the correct option is B.

Nuclear power comes from nuclear fission

The steam is used to spin large turbines that generate electricity. Nuclear power plants use heat produced during nuclear fission to heat water. In nuclear fission, atoms are split apart to form smaller atoms, releasing energy

In nuclear power plants, neutrons collide with uranium atoms, splitting them.  In the core of nuclear reactors, the fission of uranium atoms releases energy that heats water to about 520 degrees Farenheit. This hot water is then used to spin turbines that are connected to generators, producing electricity
