2.Organisms that are best suited for survival in their environment will be able to compete for limited resources better than organisms that are not well suited to their environment.

3.Hibernation is a way animals conserve energy to survive adverse weather conditions or lack of food. It involves physiological changes such as a drop in body temperature and slowed metabolism.

4."survival of the fittest" is a popular term that refers to the process of natural selection, a mechanism that drives evolutionary change. Natural selection works by giving individuals who are better adapted to a given set of environmental conditions an advantage over those that are not as well adapted.

5.This led to Darwin developing his theory of adaptation.

Darwin's adaptation theory, also known as survival theory or survival of the fittest, ans states an organism's ability to adapt to changes in its environment and adjust accordingly over time

6.c

7.The similarities between different types of an organism can be explained by the theory that they all come from a common ancestor. The differences between them are due to changes over time that have developed through natural selection.

8.Natural selection is the process by which organisms which are not as well adapted to their environment do not survive long enough to pass their less favorable traits on to the next generation of their species.

What is true for two pieces of iron at the same temperature that are different mass?

A) The average kinetic energy of their particles is different.
B) Heat flows from the larger object to the smaller object.
C) The total thermal energy of their particles is different.
D) Heat flows from the smaller object to the larger object.

Answers

Answer:

Their particles have the same total kinetic energy.

Explanation:

Their particles have the same total kinetic energy.

C) The total thermal energy of the particles in each piece of iron will be different, because the total energy of a substance is proportional to its mass. However, if they are at the same temperature, their average thermal energy per particle will be the same.

Which type of selection is shown in the graph above?
A. Disruptive selection
B. Stabilizing selection
C. Disaster Selection
D. Directional selection

Answers

The anwser is A Disruptive selection

In the given graph, the Evolved Population is showing disruptive selection. Hence, the correct option is A. Disruptive selection.

Stabilizing selection is a form of natural selection where individuals with average phenotypes are more likely to survive and reproduce their number. In this selection, the population tends to maintain a stable phenotype. As shown in the graph, the population is maximum for the population having a moderate length of neck.

Disruptive selection is a type of natural selection where extreme phenotypes are preferred over average phenotypes, leading to an increase in genetic variation and the population becoming more diverse. In this type of selection, the population diverges into two or more distinct phenotypic groups. As shown in the graph, two ranges of the population are favored for having traits for extreme lengths of the neck.

What is an ellipse please help)

Answers

normal oval shape traced by a point moving in a plane so that the sum of the distance from the other points is constant.

In mathematics, an ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant. As such, it generalizes a circle, which is the special type of ellipse in which the two focal points are the same.

these days cloths made out of a mixture of synthetic fiber and natural fibers are more popular than those made purly out of synthetic fiber. Discuss the reason for this

Answers

Answer: Clothes purely made of synthetic fibers are not comfortable in a hot and humid environment as they don't have the property to absorb water or sweat quickly so their water-resistant property makes them unsuitable for hot humid environment .

Explanation:

Mixing of synthetic fiber and natural fibers enhances the properties such as strength, elasticity, and ease of ironing and washing. Generally in hot environments it is preferred to wear a mixture of synthetic and natural fiber than wearing only clothes made from synthetic fiber .

Moreover, mixing synthetic fibres with natural fibres enhances their properties, such as strength, elasticity and ease of washing and ironing. Hence, these days clothes made out of a mixture of synthetic fibres and natural fibres are more popular than those made purely out of synthetic fibres.

What needed to be present in marine mud to form fossil fuels?

Answers

Carbon and Hydrogen.

Answer:

Mostly decaying organisms are needed to present in marine mud to form fossil fuels.

Explanation: When organisms and plants died and sank to the bottom of swamps and oceans, brown soil-like materials called peat are formed. Over millions of years, the peat became covered with sand, clay and other minerals and the peat is converted into layers of sedimentary rocks. After a long time, different type of fossil fuels are formed.

When the speed of the bottle is 2 m/s, the KE is kg m2/s2. When the speed of the bottle is 3 m/s, the KE is kg m2/s2. When the speed of the bottle is 4 m/s, the KE is kg m2/s2. When the speed of the bottle is 5 m/s, the KE is kg m2/s2. When the speed of the bottle is 6 m/s, the KE is kg m2/s2.
instructions
In this part of the experiment, you will be changing the speed of the bottle by dropping it from different heights. You will use the same mass, 0.250 kg, for each trial, so record this mass in Table B for each velocity. Then, calculate the expected kinetic energy (KE) at each velocity. Use the formula KE = mv2,
where m is the mass and v is the speed. Record your calculations in Table B of your Student Guide.

Answers

Answer:

Based on the given instructions, you need to calculate the expected kinetic energy (KE) at each velocity using the formula KE = mv^2, where m is the mass and v is the speed. The mass is given as 0.250 kg.

Table B: Calculation of Kinetic Energy (KE)

Speed (m/s)Mass (kg)KE (kg m^2/s^2)20.2500.50030.2500.75040.2501.00050.2501.25060.2501.500

To calculate the kinetic energy at each velocity, multiply the mass (0.250 kg) by the square of the velocity.

For example, when the speed of the bottle is 2 m/s: KE = (0.250 kg) * (2 m/s)^2 = 0.250 kg * 4 m^2/s^2 = 1.000 kg m^2/s^2

Perform similar calculations for the other velocities and record the results in Table B.

Answer:

Explanation:mass of the bottle in each case is M = 0.250 kg

now as per given speeds we can use the formula of kinetic energy to find it

1) when speed is 2 m/s
