Answer:
110 kg
Explanation:
Given
Acceleration (a) = 3m/s²
Force (F) = 330N
Required
Determine the mass of the motorcycle
This question is an illustration of Newton's second law and will be solved using:
Force = Mass * Acceleration
F = m * a
This above implies that force applied on the motorcycle is a product of its mass and its acceleration
Substitute values for F, and a
330N = Mass * 3m/s²
Make Mass the subject
Mass = 330N/3m/s²
Mass = 110kg
Hence, the calculated mass of the motorcycle is 110kg
Answer:
110

why are cell membranes are described as phospholipid bilayers?
Answer:
Phospholipids, arranged in a bilayer, make up the basic fabric of the plasma membrane. They are well-suited for this role because they are amphipathic, meaning that they have both hydrophilic and hydrophobic regions. Chemical structure of a phospholipid, showing the hydrophilic head and hydrophobic tails.

Let's look at the original hypotheses arising from the original question: "Does the size of the
substance affect its ability to diffuse across cell membranes?"
Small substances: If the size of a substance is important in its ability to
diffuse across a cell membrane, then small substances should be able to
freely diffuse across cell membranes.
?
Large substances: If the size of a substance is important in its ability to
diffuse across a cell membrane, then large substances should not be able
to freely diffuse across cell membranes.

Do the observations of H+?glucose and cortisol support the
hypotheses?
Explain your answer
Answer:
H1: false, the observations of the molecules do not support the hypothesis...
Explanation:
The cell membrane is comprised of a phospholipid bilayer, proteins, and cholesterol. These components help the membrane to maintain its selective permeability and concentration of solutes and water.
The lipid molecules have polar hydrophilic heads and hydrophobic tails. These only readily allow for the movement of small non polar molecules. Other substances, like charged ions and large molecules require transport proteins to move in and out of the cell. Hypothesis: H+ is small and should be able to move freely through the membrane, While glucose is large and cannot move freely
Observing H+, despite being very small these cannot easily pass through the membrane. They require transport proteins called channels for their free movement or passive movement across the membrane.For glucose, these molecules pass through specialized channels in facilitated diffusion. They move down their concentration gradient into the cell. To move out of the cell against its concentration gradient glucose requires ATP for active transport.Cortisol, is a large steroid hormone, taken into the cell by simple diffusion across the lipid membrane, down its concentration gradient.Which best describes the nucleus of an atom?

Explain how the daily energy needs are different between the zebra and its predator, the lion. Be certain to include any pertinent differences in the digestibility of these organisms’ food sources, along with differences in digestive tracts and energy spent on digesting. Cite any behaviors you feel may play a role as well.
Answer:
Both animals eats different types of food so they have different digestive system.
Explanation:
The daily energy needs are different between the zebra and its predator, the lion because they have difference in daily activities and they eat different types of food and. Zebra is herbivorous animal while the lion is carnivorous so there is highly difference occurs in their digestive system. Zebra activities is to eat plants and run from the prey which needs more calories but the lion needs very high amount of calories for catching their pray for food.

1. In cellular respiration, stored energy is released from ____________ molecules and transferred to ____________ molecules, which cells can use to provide energy for cellular processes.
Answer:
Glucose, and ATP.
Explanation:
During cellular respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP.
In cellular respiration, stored energy is released from glucose molecules and transferred to ATP molecules, which cells can use to provide energy for cellular processes.
CELLULAR RESPIRATION:
Cellular respiration is the process by which living organisms obtain energy by breaking down food molecules in their cells. Cellular respiration is a requirement for every living cell in order to produce the energy needed for metabolic activities. Cellular respiration, generally, combines glucose molecule and oxygen according to the following reaction:C6H12O6 + 6O2 → 6CO2 + 6H2O + ATPBased on the equation above, stored energy is released from glucose molecules and transferred to ATP molecules, which cells can use to provide energy for cellular processes.Learn more at: https://brainly.com/question/13721588?referrer=searchResults
How many O2 molecules are required for two glucose molecules to undergo cellular respiration?
18
6
12
2
The number of O2 molecules required for two glucose molecules to undergo cellular respiration would be 12.
First, let us look at the balanced equation of respiration:
[tex]C_6H_1_2O_6 + 6O_2 ---> 6CO_2 + 6H_2O[/tex]
From the equation, for every 1 mole of glucose molecule, 6 moles of O2 is required for complete reaction.
Thus, 2 glucose molecules will require 6 x 2 = 12 moles of O2.

Explain the relationship between the processes of breathing and cellular respiration
Cellular respiration uses oxygen to release the energy stored in food.
Explanation:
In breathing living organisms take oxygen and release the carbon dioxide it is similar to the aerobic respiration.
There are two types of respiration:
1. Aerobic respiration
2. Anaerobic respiration
Aerobic respiration
It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.
Glucose + oxygen → carbon dioxide + water + 38ATP
Anaerobic Respiration
It is the breakdown of glucose molecule in the absence of oxygen and produce small amount of energy. Alcohol or lactic acid and carbon dioxide are also produced as byproducts.
Glucose→ lactic acid/alcohol + 2ATP + carbon dioxide!
