People spray pesticides on crops to kill insects that eat and destroy the crops. However, these insects are becoming resistant to the pesticides. Explain how this could happen.
When an organism or insect develops a mechanism for the removal of the pesticide compound is known as pesticide resistance.
What is pesticide resistance?The organism or insects develop mechanisms such as the alternation of the binding site of the compound present in the pesticide leading to the development of resistance against the used pesticides. The development of resistance against the pesticide is a slow process, it takes time. The usage of pesticides becomes a failure if organisms develop resistance.
The frequent use of pesticide and insecticides cause changes in the genetic material of the organisms. They help in the development of enzymes and changes in the binding sites. These changes are passed on to the next generation of the organism, which makes the entire population resistant to the particular pesticide and insecticide.
The use of the chemicals should be monitored. Only use when required with rotation.

Which best describes the importance of carbohydrates to organisms?
A. Carbohydrates provide an additional source for amino acids.
B.Carbohydrates provide an immediate energy source
C. Carbohydrates provide permanent storage for genetic information.
D.Carbohydrates provide storage for water molecules
Answer:
[tex]\boxed {\boxed {\sf B. \ Carbohydrates \ provide \ an \ immediate \ energy \ source}}[/tex]
Explanation:
Carbohydrates are important because they provide the body with energy. It's essential to consume the correct amount of carbohydrates for your body, but make sure they are healthy (examples: whole grain, squash, sweet potatoes, beans)
Carbohydrates are easy for the body to break down. The body will digest these first into simple sugars, like glucose. The glucose is then used in cellular respiration to produce ATP or energy.
Therefore, carbohydrates can quickly provide energy for the body. The best answer choice is B.
Answer:
Carbohydrates provide energy to organisms.
Explanation:
I'm 100% sure because Carbohydrates can also be defined chemically as neutral compounds of carbon, hydrogen and oxygen. Carbohydrates come in simple forms such as sugars and in complex forms such as starches and fiber. The body breaks down most sugars and starches into glucose, a simple sugar that the body can use to feed its cells

Which of the following is an autotroph?
Shark
Fish
Snail
Algae
Fungus
Algae is an autotroph. Autotrophs include organisms including plants, algae, plankton, and bacteria. Producers, primary consumers, secondary consumers, and tertiary consumers make up the food chain.
An autotroph is what?An organism that can manufacture food by utilizing light, water, carbon dioxide, or other chemicals is known as an autotroph. Autotrophs are occasionally referred to as producers since they grow their nourishment. Although the most well-known autotroph is a plant, there are numerous more types of autotrophic creatures.
What exactly are heterotrophs and autotrophs?Autotrophs are referred to as producers since they can generate their food using energy and raw resources. Plants, algae, and several varieties of bacteria are examples. Heterotrophs are known as consumers because they devour producers or other consumers. Humans, dogs, and birds are all instances of heterotrophs.

All cells contain two proteins called actin and myosin? True or false
Answer: i think its true
Explanation:
True that all eukaryotic cell i.e. muscle cells. contains actin and myosin protein .
What are actin and myosin protein?Actin filaments are responsible for a variety of cell motions, generally in conjunction with myosin. Myosin is a molecular motor prototype—a protein that transfers chemical energy in the form of ATP into mechanical energy, allowing it to generate force and movement. Muscle contraction is the most noticeable type of such movement, and it has served as a model for studying actin-myosin interactions and myosin motor activity. Actin and myosin interactions, on the other hand, are essential for not just muscle contraction but also a range of non muscle cell motions, including cell division, making them important in cell biology.Actin is a protein found in all eukaryotic cells. Actin filaments move along filaments of another protein called myosin to cause cells to contract. It was initially found in skeletal muscle. Actin filaments are less structured in non muscle cells, and myosin is considerably less prominent.Hence, the given statement is true.

b. It unites with amino acids in the cytoplasm
c. It contains uracil, which functions in protein synthesis
d. It consists of alternating phosphates groups and deoxyribose molecules
Answer:
d. It consists of alternating phosphates groups and deoxyribose molecules
Explanation:
The statement above best describes a portion of the molecule that is represented here.
Actually, the molecule represented here is the Deoxyribonucleic acid (DNA). The molecule is composed of two polynucleotide. The DNA carries genetic properties that lead to growth, development, reproduction and functioning of organisms. The phosphate group and deoxyribose molecule are found attached to the DNA. The phosphate group is also found in RNA and in ATP. The deoxyribose is known to be a five-carbon sugar molecule which helps to form the phosphate backbone of DNA molecules.
The given molecule is consists of alternating deoxyribose molecules and phosphates groups.
DNA:

Explain how water is used to create electricity.
Answer:
Explanation:Flowing water creates energy that can be captured and turned into electricity.The most common type of hydroelectric power plant uses a dam on a river to store water in a reservoir. Water released from the reservoir flows through a turbine, spinning it, which in turn activates a generator to produce electricity.
Answer:
Water can be used in a lot of ways, let say that you have a big paddle by a raging river next to you to power your home, this paddle can keeping continuously moving to power that home based off how much that river is going. This is one way that water can be used to make electricity. Hope this helps, Merry Christmas, and have a nice day!

Write a paragraph explaining the function of a cell wall and cell membrane and why plants have cell walls and animal cells do not.
plssssssssssssssssssssssss a good paragraph with good vocabulary
A cell wall is a structural layer surrounding some types of cells, just outside the cell membrane. It can be tough, flexible, and sometimes rigid. It provides the cell with both structural support and protection, and also acts as a filtering mechanism.[1] Cell walls are present in most prokaryotes (except mollicute bacteria), in algae, fungi and eukaryotes including plants but are absent in animals. A major function is to act as pressure vessels, preventing over-expansion of the cell when water enters.
