Answer:

,Mass of the Body = 10 kg.

Height = 10 m.

Acceleration due to gravity = 9.8 m/s².

Using the Formula,Potential Energy = mgh

= 10 × 9.8 × 10 = 980 J.

(b). Now, By the law of the conservation of the Energy, Total amount of the energy of the system remains constant.

∴ Kinetic Energy before the body reaches the ground is equal to the Potential Energy at the height of 10 m.

∴ Kinetic Energy = 980 J.

(c). Kinetic Energy = 980 J.

Mass of the ball = 10 kg.

∵ K.E. = 1/2 × mv²

∴ 980 = 1/2 × 10 × v²

∴ v² = 980/5

⇒ v² = 196

∴ v = 14 m/s.

3. Yes - At maximum stretch the ball stops. The ball is now 2 meters plus x below the starting point where x is the stretch distance down. The total energy is all potential in the springs and gravitational and is m g (2 + x)

Answer:

A,B,C,D

Explanation:

Since one parent is CC, there is no way to get cc as an outcome from this cross. However, there is also no way that all of the offspring will be CcDd, which is heterozygous for both traits. Therefore, this is the only answer choice that is incorrect.

As per observation about the  two individuals that have the following genotypes: CCDd and Ccdd the cross are options: a,b,c,d.

Since one parent is CC, there may be no manner to get cc as an final results from this cross. However, there may be additionally no manner that every one of the offspring could be CcDd, that is impure breed for each traits.

Genotype is an individual's series of genes. The time period can also talk to the 2 alleles inherited for a specific gene. The genotype is expressed while the statistics encoded within side the genes' DNA is used to make protein and RNA molecules.

Thus it is clear that all the observations are correct.

Answer:

D they are mistaken by wasps

The most likely explanation for why some species of hover flies resemble wasps in body coloring and shape is that they are mistaken for wasps and avoided by predators (Option D).

Adaptation refers to the process of change in an organism's traits or characteristics over time in response to environmental pressures such as competition, predation, or changing resource availability. Adaptations can be physical, physiological, or behavioral, and they can help an organism to better survive and reproduce in its environment. For example, an organism that lives in a dry and arid environment might develop adaptations such as a deep root system to tap into subterranean water sources or a reduction in body size to reduce water loss through respiration.

Adaptations can occur through natural selection, where traits that are advantageous for survival are more likely to be passed on to future generations, or through other mechanisms such as genetic drift or mutation.

Answer:

weathering occurs when rocks sit in a pool of salt water. weathering or eroding

Explanation:

The Chemical Weathering that is caused here is Solution Weathering.

Weathering is defined as the breaking down or dissolving of rocks and minerals on the surface of the Earth.

Weathering is a slow and irregular process caused by different factors called agents which are - Water, Ice, Acids, Salts, Temperature.

Weathering along with Erosion constantly keeps on changing the geography of the earth as it lead to change in the landscape of the earth.

There are three major types

1. Physical Weathering

2.Chemical Weathering

3. Biological Weathering

Physical Weathering:

Physical Weathering is also known as mechanical weathering is the process causing integration without climate change.

The primary process involved in it is Abrasion.

Factors involved are- Temperature, Pressure, Frost

It is prominent in little or no vegetative area such as deserts, mountains

Chemical Weathering:

Chemical Weathering changes rock composition transforming into different chemical reactions when interact with minerals.

This weathering is a gradual and ongoing process as the rock minerology adjust to the environment near the surface.

The most important process involved here is Oxidation and Hydrolysis.

The process is enhanced by water, oxygen, biological agent such as microbial and plant root metabolism acids.

Chemical Weathering occurs faster at higher temperature with warm and humid conditions.

Chemical Weathering is further divided into- Solution, Hydrolysis and Oxidation

Solution Weathering-  Removal of rock by acidic rainwater in solution i.e. dissolved CO2 containing rainwater. This process is also known as Carbonation.

Hydrolysis Weathering- Acidic water breakdown of rock producing clay and suitable soils.

Oxidation Weathering- Rock breakdown by oxygen and water giving rusty appearance .

Biological Weathering:

It is the weakening and subsequent breakdowns by plants, animals and microbes of rock.

Growing roots of plants can put pressure on rock and this weathering can also lead to chemical weathering.

Microbial activity breaks down rock minerals by altering chemical composition of the rock making it more weather sensitive.

Answer:

Oysters were keeping the nutrient levels relatively stable in the bay by filtering the nutrient sewage, animal waste, and fertilizer that was running into the bay.

Explanation:

Answer:

Water moves by gravity into the open pore spaces in the soil, and the size of the soil particles and their spacing determines how much water can flow in. Wide pore spacing at the soil surface increases the rate of water infiltration, so coarse soils have a higher infiltration rate than fine soils.

How does soil particle size affect permeability?

But permeability is a different thing. It increases as particle size increases. By definition, permeability is a MEASURE OF EASE with which fluids will flow though a porous rock, soil or sediment. ... That means capillarity increase as particle sizes decreases.

Answer:

Energy in the form of heat is released as chemical potential energy is transferred from glucose molecules to ATP molecules

The statement that best explains the movement of energy through aerobic cellular respiration is as follows:

Thus, the correct option for this question is C.

Aerobic cellular respiration may be defined as a type of biological process through which the molecules of glucose are broken down into carbon dioxide and water in the presence of oxygen with the liberation of some amount of energy. The derivation of energy is the fundamental mechanism of this process.

The mechanism initiate after capturing the heat energy from the and transforming it into chemical energy through the process of photosynthesis which synthesizes glucose. This glucose is then transferred to its potential energy to the ATP molecules in the presence of oxygen.

Therefore, heat energy is released as chemical potential energy is transferred from glucose molecules to ATP molecules. Thus, the correct option for this question is C.

I think it is quite an interesting idea to allow parents to 'design' their children before birth. Because some people have preferences and those preferences are taken very seriously. I wouldn't want to have a baby boy, I would want a baby girl. Although, this could be a waste of money and time because this might be one of the things that are better not to be fixed even if it isn't broken. But, this can also be good, if you desperately need a child with specific features, this can help. Even if I can't seem to find a reason where a child is supposed to have specific features.

Explanation:

The alteration of the natural gene by the tools is called genetic engineering. The application of genetic engineering is to make transgenic animals that give protein-rich products and transgenic plants which are disease-free.

The idea of genetic engineering is quite subjective. some people find it right and some find it wrong. In order to evolve biological science, genetic engineering is important but ethically and morally genetic engineering is not good as we altering nature's work.

Genetic engineering allows a parent to check the genetic disease of the child and help them to cure it but it is ethically wrong if they used it to find the sexual gender of the child.

Hence, genetic engineering is wrong in a limited way.

Explanation:

Genetic variation is a measure of the genetic differences that exist within a population. Genetic variation is essential for natural selection because natural selection can only increase or decrease frequency of alleles that already exist in the population. Genetic variation is caused by: mutation.

Answer: Genetic variation is important to the processes of natural selection and biological evolution. The genetic variations that arise in a population happen by chance, but the process of natural selection does not. Natural selection is the result of the interactions between genetic variations in a population and the environment.
