Answer:

Independent Assortment

Explanation:

Inheritance of one gene does not guarantee the inheritance of another.

Answer:

Explanation:

This question is incomplete because of the absence of the graph. However, the independent variable of an experiment is the variable that is not affected by any other variable during the course of the experiment but is however intentionally or unintentionally predetermined by the researcher conducting the experiment. For example, in an experiment to determine the effect of age on blood pressure; age is the independent variable because the age class/groups of the individuals to be used can be determined by the researcher also the age cannot be affected by the pressure (the age of a person cannot change because of an increase/decrease in blood pressure).

Also, the control of an experiment is the variable/data in which other data in the same experiment are compared to. For example, in an experiment to determine the effect of a substance (such as sepin-1) on the growth of cancer cells (using a culture medium), the control can be the culture medium that was not given any substance or the culture medium that was given a pure substance of no effect like water. This means, in this control culture medium, the cancer cells will continue to grow normally while that growth will be compared with what is seen in the culture medium treated with sepin-1.

Answer:

Lipids have 3 main functions, they store energy, they are important signaling molecules, and they make up the components of cell membranes.

more light means more photosynthesis means more oxygen

closer to light the more oxygen is produced

distance from light & oxygen produced is in an inverse relationship which means when one goes up the other goes down

According to the data on the table, when the distance from the light increased, the bubbles produced per minute have decreased. The relationship between the two variables shows an inverse one. This means that if one variable increases, then the other one decreases, and vice-versa. Using this information, we can conclude that when the aquatic plant is placed far from light, it gets less sun exposure. This affects the rate of photosynthesis, including its by-products. When the rate of photosynthesis is slow, the oxygen produced as a waste product is also low.

quizlet

Answer:

The Sun's gravitational pull on the Earth would decrease.

Explanation:

According to Newton's laws,  if its orbit moved farther away from the Sun, the Sun's gravitational pull on the Earth would decrease. The correct option is d.

Gravitational force is the force that attracts everything towards it. The third law of Newton, or the law of action-reaction, states that:

As soon as object A applies a force (referred to as an action) to item B, the opposite force is then applied to the first object (referred to as a reaction).

In other words, when two things exert a force on one another, the two forces have the same magnitude (while the directions are opposite).

The gravitational force that the Earth exerts on the Sun is consequently equivalent to and, in fact, opposite of the gravitational force that the Sun exerts on the Earth, according to Newton's third law.

Therefore, the correct option is d. The Sun's gravitational pull on the Earth would decrease.

Answer:

1. Water Condenses on an Aluminium Can. Water condenses on a can of cold soda. Water vapor in the air reaches its dew point as it cools in the air around the can, forming liquid drops of water. Condensation is the process where water vapor becomes liquid.

2. The Kelvin temperature of a substance is directly proportional to the average kinetic energy of the particles of the substance. For example, the particles in a sample of hydrogen gas at 200 K have twice the average kinetic energy as the particles in a hydrogen sample at 100 K.\

3. A water boiling

Explanation:

1) What has taken place on the outside of the coke can by the movement of the particles is called; Condensation

2) The relationship between temperature and the transfer of kinetic energy is that; temperature is directly proportional to the kinetic energy.

3a) Water Boiling; From liquid to Gas

3b) Popsicle freezing; From liquid to solid

3c)Water condensing on the side of a water bottle; From gas to Liquid.

1) Since a cold can is left on the table at room temperature, it means that it will began to get warm because room temperature is warm. This means the cold can will begin to get less cold and become warm and in this process, it gives off water vapour from the body of the can. This water vapor becomes liquid on the surface of the can in a process known as condensation.

This is because condensation is when water vapor becomes liquid.

2) Kinetic energy is the energy of a substance when its molecules are in motion. Thus, the more heat gained by a substance, the more speed will be gained by the molecules and consequently lead to an increase in kinetic energy.  Thus, temperature is directly proportional to the kinetic energy.

An example, is when we are boiling water water. The more the temperature at which the water heated is increased, the faster the molecules of the water will be and as a result the kinetic energy transferred to the water will also increase.  

3a) Boiling Water; When we boil water, we are basically converting water to steam. This is because the higher the temperature, the higher will be the kinetic energy of the water molecules and at 100°C, liquid water changes state to gas which is steam.

3b) Popsicle Freezing; In contrast to boiling when the temperature is increased, in freezing the temperature is reduced and as a result there is little to no movement between the particles which means that the kinetic energy is very low and as a result the particles come together and begin to bond with each other in freezing. Popsicle is liquid ice cream and as such in freezing changes from liquid to solid.

3c) Water condensing on the side of a water bottle; From question 1 above, this process is called condensation where there is a change of state from gas(water vapour) to liquid.

The various greenhouse gases' varying contributions to global warming are as follows: planting trees can reduce CO2 by 60%. More carbon dioxide is removed from the atmosphere by trees than is released.

Storms, heat waves, floods, and droughts are just a few of the disasters that are getting worse as a result of rising temperatures. Warmer temperatures produce an atmosphere that can hold onto, release, and gather more water. This alters weather patterns such that wet areas get wetter and dry ones to get drier.

The heat from the sun gets trapped on Earth as a result of greenhouse gas production. Global warming and climate change result from this. The rate of global warming is presently higher than it has ever been. Weather patterns are shifting as a result of warming temperatures, which is also upsetting the natural order.

Lipids, which are employed by cells to obtain and store energy, are the proper response.

The storage of energy in the form of neutral lipids like triglycerides and sterol esters is the primary function of lipid droplets (LDs), intracellular organelles. They are common organelles that can be found in bacteria, fungi, plants, and even animals. LDs are made up of a polar lipid monolayer with many different proteins, some of which are involved in lipid metabolism, around a core of neutral lipids. Diglyceride acyltransferase 1 (DGAT1) and other enzymes that synthesize neutral lipids in the endoplasmic reticulum (ER) membrane cause the emergence of nascent LDs, which are organelles that are partially or entirely different from the ER.

A man and his wife both have normal vision, but their daughter has red-green color blindness, a sex linked recessive trait. This is possible due to the inheritance of the sex-linked recessive trait.

The female child inherits an X chromosome from each parent. If the mother is a carrier of the gene for red-green color blindness, the daughter has a 50% chance of inheriting this trait. However, if the father is the one carrying the gene, then the daughter will have a 100% chance of inheriting the trait. This is due to the fact that the mother will pass on either an X chromosome with the gene or an X chromosome without the gene, but the father will always pass on an X chromosome with the gene because he does not have a Y chromosome to pass on. Thus, if the father is the one carrying the gene, the daughter will always inherit the trait.

By analyzing fossils, pollen, soil samples, and other indicators, archaeologists can recreate past environments, ecosystems, and subsistence practices. They can see how people adapted to climate-induced changes in vegetation, water sources, and animal migrations. For example, changes in hunting strategies, toolmaking techniques, and settlement patterns are often related to shifts in climate.

Specific challenges we have today that Mesolithic people didn't have to deal with include the large-scale burning of fossil fuels, which is contributing to the warming of the planet. This is a challenge that requires global cooperation and political will to address. Archaeologists and their specialized knowledge of the past can influence the climate change debate by providing a long-term perspective and demonstrating the impact of human activities on the environment. They can also contribute to interdisciplinary research that brings together scientists, policymakers, and community stakeholders to develop strategies for mitigating and adapting to climate change.
