Which cell structures work together to form a pseudopod?
A. cell wall and nucleus
B. eyespot and chloroplast
C. cytoplasm and plasma membrane
D. contractile vacuole and mitochondria
cytoplasm and plasma membrane
Pseudopodia are formed by some cells of higher animals (e.g., white blood corpuscles) and by amoebas. During amoeboid feeding, pseudopodia either flow around and engulf prey or trap it in a fine, sticky mesh.
Calculate the total resistance (in Ohms) of a light bulb marked 2V and 3A. Do not add units. Leave your answer as a decimal to 2 decimal places.
The total resistance of a light bulb marked 2V and 3A is 0.67ohms
HOW TO CALCULATE RESISTANCE:
The resistance of a substance can be calculated by using the formula as follows:R = V/I
Where;
R = resistance (in ohms)V = voltage (in volts)I = current (in amperes)According to this question, a light bulb is marked 2V and 3A. The resistance (R) can be calculated as follows:R = 2V ÷ 3A
R = 0.67ohms.
Therefore, the total resistance of a light bulb marked 2V and 3A is 0.67ohms.Learn more at: https://brainly.com/question/8776047?referrer=searchResults

how fast does a body decompose to skeletal remains?
Answer:
Timeline. In a temperate climate, it usually requires three weeks to several years for a body to completely decompose into a skeleton, depending on factors such as temperature, humidity, presence of insects, and submergence in a substrate such as water.
Explanation:
Water is extremely important to the survival of all organisms found on Earth.
Water helps support life in many ways. These life providing properties of water
are all basically derived from water's ability to form Hydrogen bonds, as a result
of it being a polar molecule. Describe a typical Hydrogen bond between
Hydrogen and Oxygen.
Your answer
Answer:
Water is called the "universal solvent" because it is capable of dissolving more substances than any other liquid. This is important to every living thing on earth. It means that wherever water goes, either through the air, the ground, or through our bodies, it takes along valuable chemicals, minerals, and nutrients.
Explanation:
SO THE ANSWER IS (A): Water helps support life in many ways. These life providing properties of water.

Which of the following is the best example of a way human lifestyles affect environmental systems?
Using radioactive materials causes ground pollution as it causes methane to seep into the ground.
Burning fossil fuels causes water pollution by increasing the amount of water vapor in the atmosphere.
Deforestation causes acid rain by decreasing carbon dioxide (CO2) in the atmosphere.
Using aerosols that contain chlorofluorocarbons (CFCs) decreases the amount of protective ozone (O3).
Answer:
Burning fossil fuels causes water pollution by increasing the amount of water vapor in the atmosphere.
Explanation:
This is the best example because when burning fossil fuels, greenhouse gases are released, which can cause global warming. This affects the environment.

Which of the following is not a lipid?
Asteroid
B cholesterol
C
wax
D cellulose
Answer:
cellulose
Explanation:
lipids are fats oils or waxes. cellulose is a fiber
Answer:
cellulose
Explanation:
Examples of lipids include fats, oils, waxes, certain vitamins (such as A, D, E and K), hormones and most of the cell membrane that is not made up of protein. Therefore waxes are not the answer.
Steroids are lipids because they are hydrophobic and insoluble in water, but they do not resemble lipids since they have a structure composed of four fused rings. Cholesterol is the most common steroid and is the precursor to vitamin D, testosterone, estrogen, progesterone, aldosterone, cortisol, and bile salts. Therefore steroid and cholesterol is not the answer.

Which statement correctly demonstrates the relationship between cellular respiration and photosynthesis?
A: The ATP produced by all cells during cellular respiration can be used by plant cells to produce water molecules during photosynthes
B: The glucose produced by plant cells during photosynthesis can be used by all cells to produce ATP during cellular respiration.
C: The oxygen produced by all cells during cellular respiration can be used by plant cells to produce glucose during photosynthesis.
D: The water molecules produced by plant cells during photosynthesis can be used by all cells to produce oxygen during cellular O respiration.
Answer:
your answer is B. The glucose produced by plant cells during photosynthesis can be used by all cells to produce ATP during cellular respiration.
Explanation:
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
