Answer:

The defining feature of a eukaryotic cell is the presence of a nucleus. Most animals and plants have eukaryotic cells.

Explanation:

Eukaryotic cells have a nucleus, and membrane-bound organelles All multicellular organisms are made up of eukaryote cells

Eukaryotic cells are one of the two types of cell types prokaryotic and eukaryotic. There are various structural and functional differences found in them.

Eukaryotic cells are defined by:

Eukaryotic organisms have various range of organisms including mostly all multicellular such as animals, plants, fungi, and protists, as well as most algae. Eukaryotes can be single-celled as well.

Thus, the eukaryotic cells have a nucleus, All multicellular organisms are made up of eukaryote cells

Answer:

Most environmental issues are problems on a global scale, these include but are not limited to, global warming, ozone pollution, greenhouse gases and many more issues.

This affects the way we try to solve these issues because if we dont all play a part to help change the way things are going, then they will only get worse. We have to come together as a whole.

Unlike individual efforts, different countries can cooperate and implement legislation which limitates all the countries in the globe,solving environmental issue more efficiently.

Answer:

As the Burmese python surpasses its carrying capacity in South Florida, the overpopulation of it leaves less resources for each python, and other organisms. Predators may have way too many pythons, and not be able to keep the balance, and prey might be over hunted or eaten. The population sizes may decrease due to the over-population of the pythons.

Explanation:

If there are ever too many of any ORGANISM in a ecosystem, the balance is sure to be ruined.

8. Decomposers are organisms (bacteria and fungi) that break down dead organisms. They could be at all trophic levels

9.  pyramid of energy shows how much energy is retained in the form of new biomass at each trophic level, while a pyramid of biomass shows how much biomass (the amount of living or organic matter present in an organism) is present in the organisms.

10. energy is lost at each level. Most of the energy lost is lost as heat. Food webs and food chains both involve multiple trophic levels.

Answer:

D. thrombocytes​

Explanation:

The main function of thrombocytes is to stop the bleeding of injured blood vessels. In mammals, thrombocytes are anucleated cell fragments called platelets.

Thrombocytes is responsible for the clotting of blood.

The microscopic blood cells known as platelets, or thrombocytes, aid in blood coagulation. Your body naturally stops bleeding with platelets.

Plasma, red, white, and platelet-containing blood cells make up whole blood. Platelets, the lightest component of whole blood, are pushed to the walls of your blood vessels because they are the heaviest part of the blood.

This allows plasma and blood cells to flow through the center, allowing platelets to reach injury rapidly to stop bleeding.

Therefore, Thrombocytes is responsible for the clotting of blood.

Answer:

Cell membranes restrict diffusion of highly charged molecules, such as ions, and large molecules, such as sugars and amino acids.

Explanation:

Cell membranes serve as barriers and gatekeepers. They are semi-permeable, which means that some molecules can diffuse across the lipid bilayer but others cannot. Small hydrophobic molecules and gases like oxygen and carbon dioxide cross membranes rapidly. Small polar molecules, such as water and ethanol, can also pass through membranes, but they do so more slowly. On the other hand, cell membranes restrict diffusion of highly charged molecules, such as ions, and large molecules, such as sugars and amino acids. The passage of these molecules relies on specific transport proteins embedded in the membrane.

Cellular respiration or aerobic respiration is a series of chemical reactions which begin with the reactants of sugar in the presence of oxygen to produce carbon dioxide and water as waste products.

Answer:

The cell membrane, therefore, has two functions: first, to be a barrier keeping the constituents of the cell in and unwanted substances out and, second, to be a gate allowing transport into the cell of essential nutrients and movement from the cell of waste products.

it has one side that is positively charged and one side that is negatively charged

Answer:

D

Explanation:

A water molecule, because of its shape, is a polar molecule. That is, it has one side that is positively charged and one side that is negatively charged. The molecule is made up of two hydrogen atoms and one oxygen atom. The bonds between the atoms are called covalent bonds, because the atoms share electrons.

Answer:

Natural Selection is survival of the fittest aka Darwinism. It basically states that the strongest survive and the weakest don't. Maybe it's through food shortages, bad weather, or predators. It occurs in an organism for population control. If there is too big of a population, then there will be a recourse drought and natural selection will do its thing again.

Answer: B

Explanation: Because the Red shows activity

Activation energy is defined as the minimum amount of energy required for activating the atoms or molecules to undergo chemical transportation or transfer.

The correct answer is:

Option D. The letter A.

In the graph, activation energy can be explained as:

1. The activation energy is the minimal amount of energy necessary for the compounds to participate in the chemical reaction.

2. In the graph, the activation energy without the enzyme is represented by A,  the activation of energy with enzyme is represented by B, and the change in the free energy is represented by C.

Thus, the correct answer is Option D.

Answer:

Work is the transfer of energy , Energy is the capacity for doing work , and Power is work being done in a unit of time.

There are 2 types of energy

Kinetic Energy : Energy of Motion

Potential Energy : Stored Energy

When calculating work energy and power you use WORK = W=Fd

Because energy is the capacity to do work , we measure energy and work in the same units. Power's SI unit of measurement is the Watt, representing the generation or absorption of energy at the rate of 1 Joule/sec. Power's unit of measurement in the English system is the horsepower, which is equivalent to 735.7 Watts.

Answer:

0.089

Explanation:

The formula to solve for mass is:

m=F/a

So, The force is 0.1, and the acceleration is 1.25^2.

First you must square 1.25, which will give you 1.12 ( I rounded).

Now, we have 0.1/1.12, which equals 0.089, or 0.09.
