Answer:
A. Gene expression
Explanation:
Every cell has the same DNA, but because of gene expression, we have different cells in our bodies.
Gene expression turns specific genes on and off, which makes each cell have a unique function with differences in things such as protein types.
Gene expression also leads to different cells in our bodies because it changes the function of certain cells.
For example, red blood cells and white blood cells have different functions because of different gene expressions.
So, A is correct.
Due to gene expression one have different cells in the bodies.
What is gene expression?It refers to the process by which a gene gets turned on within a cell to produce proteins and RNA. Each cell in the body possesses the same DNA, however, it is because of gene expression that one possess distinct cells within the bodies.
As it makes particular genes turn on and off, therefore, each gene exhibit distinct functions with variations in the things like kinds of proteins. The gene expression also results in the formation of distinct kinds of cells due to differences in the functions performed by them.
Like platelets and white blood cells exhibit distinct functions due to distinct gene expressions. Thus, the correct answer is option A, that is, gene expression.

What kinds of molecules are used for cellular respiration?

Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water.
What is cellular respiration?Cellular respiration is the process by which biological fuels are oxidised in the presence of an inorganic electron acceptor such as oxygen to produce large amounts of energy, to drive the bulk production of ATP.
Moreover, cellular respiration is a series of chemical reactions that break down glucose to produce ATP, which may be used as energy to power many reactions throughout the body. There are three main steps of cellular respiration: glycolysis, the citric acid cycle, and oxidative phosphorylation.
Therefore, cellular respiration works either in the presence or absence of oxygen. But essentially, the process is called cellular respiration because the cell seems to “respire” in a way that it takes in molecular oxygen (as an electron acceptor) and releases carbon dioxide (as an end product).

The southern United States experiences periodic occurrences of severe cold and drought conditions. Which weather phenomenon most likely causes this and why?
La Niña, because the jet stream is displaced southwards
La Niña, because the jet stream is displaced northwards
El Niño, because of increased upwelling of cooler waters
El Niño, because of decreased upwelling of cooler waters
Answer:
D give Brainlist
Explanation:
La Nia is a climatic phenomenon that causes the surface ocean water temperature along South America's west coast to decrease. It causes the sea water's temperature to be lower than usual, hence option D is correct.
Why are periodic occurrences of severe cold and drought conditions?Lower temperatures lead the central and eastern Pacific to have higher than usual pressure, which reduces rainfall. Due to up-welling, rainfall decreases as cloud formation does.
The "ENSO," also known as the El Nino-Southern oscillation, is a cyclical climate phenomenon that periodically affects the tropical Pacific. Its warm and cool periods are called El Nino and La Nina, respectively.
Therefore, the trend switches back and forth occasionally every two to seven years, disrupting tropical wind and rainfall patterns, hence option D is correct.

In your own words explain why the color of most leaves make a good tool for photosynthesis
chloroplast is what makes the pigment green and makes photosynthesis happen. Because photosynthesis is soaking the sunlight it is he brighter green. that's why the different colored leaves happen in different seasons. with less light the less chloroplast there is.
What does she need from the food she ate and the air she breathes so that she can go on her run? How do Rosa's body systems work together to get the molecules she needs into her cells? How do her cells use these molecules to release energy for her body to run?
The missing part of the question is as follows:
Rosa eats a peanut butter sandwich for lunch. Peanut butter contains a lot of protein, and bread is mostly starch. Rosa plans to go for a run later this afternoon. Rosa is breathing normally.
Answer:
1. The food she ate is peanut butter and bread, the peanut is rich in protein while the bread is rich in carbohydrate which provides sugar (glucose) by breathing she gets oxygen in a sufficient amount to perform cellular respiration (aerobic) to carry out energy for running. Carbohydrates are a better choice of nutrients befors exercise as carbohydrates provide energy immediately.
Aerobic respiration provides a high amount of energy, 36 ATP to be specific, per cycle of cellular respiration.
2. The carbohydrates (glucose) and oxygen she gets from food and breathing react together to perform aerobic cellular respiration to carry out maximum energy. By the digestive system and organs of this system, carbohydrates are broken down into glucose which is diffused into the blood.
Oxygen also diffused to blood from the lungs and heart with the help of the respiratory and cardiovascular systems of her body.
3. By the aerobic cellular respiration process takes place in the mitochondria of the cell helps in providing energy from glucose and oxygen by a three-step process:
Glycolysis, the Krebs cycle, and oxidative phosphorylation. Here glucose reacts with oxygen. Which ultimately provide 36 ATP molecules for the cell in a run.

how are ingneous rocks formed?
Answer:
Hope this helps you mate!
Explanation:
Igneous rock (derived from the Latin word ignis meaning fire), or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava. The magma can be derived from partial melts of existing rocks in either a planet's mantle or crust.

Answer: Scientist and Park Rangers etc.
Explanation:
How does the section “Many Chemical And Physical Changes Are Happening In Nature” relate to section “Matter Isn't Lost In Photosynthesis”
This chemical change conserves matter. These plants are eaten by animals within and near the stream. Their bodies use the chemical energy stored in their bodies to power their cells and move around.
What is law of mass conservation?The law of conservation of mass usually implies that mass can never be created nor destroyed in a chemical reaction.
When coal is ignited, for instance, the carbon atom transforms into carbon dioxide. The carbon atom changes from a solid to a gas, but its mass remains constant.
According to the law of conservation of mass, mass in an isolated system is neither generated or destroyed by chemical or physical transformations.
The mass of the products in a chemical reaction must equal the mass of the reactants, according to the law of conservation of mass.
The two sentences, i.e., “Many Chemical And Physical Changes Are Happening In Nature” relate to section “Matter Isn't Lost In Photosynthesis” as during photosynthesis, mass is conserved but there are many physical and chemical transformations during the process.
Thus, this way these two statements relate to each other.

The excretory system helps the respiratory system by
O introducing more oxygen into the lungs.
O circulating blood into and out of the lungs.
O removing carbon dioxide that is produced during respiration.
O removing urine that is produced during respiration in
Answer:
The excretory system helps the respiratory system by removing carbon dioxide that is produced during respiration (third option).
Explanation:
The lungs are in charge of the breathing process, being the main organ of the respiratory system. Each lung is considered an excretory organ —belonging to the excretory system— since it is capable of eliminating the carbon dioxide (CO₂) produced by the metabolism during expiration.
As a result of the gaseous exchange, the oxygen entering the lungs through the inhaled air passes into the blood, while the CO₂ is removed from the blood. This CO₂ is removed during expiration, which makes the lungs part of the excretory system.
The other options are not correct because:
The excretory system does not introduce more oxygen into the lungs. The circulation of blood in and out of the lungs is a function of the circulatory system. Urine is not produced by breathing.Answer:
The answer is C
