Answer: Viruses are complicated assemblies of molecules, including proteins, nucleic acids, lipids, and carbohydrates, but on their own they can do nothing until they enter a living cell. Without cells, viruses would not be able to multiply. Therefore, viruses are not living things.
Would a light source be considered an internal or external stimulus?
For plants, light is an external stimulant. Phototropism is a response to light that plants have. The plant responds by orienting its growth in the direction of the light.
What is stimulus?A stimulus is an occasion or any change in the environment that causes an organ or tissue to have a certain functional response.
An external or internal trigger is possible. Sensitive to external stimuli like sound and touch are sense organs like the ear and sensory receptors like those in the skin.
Direct one-to-one stimulus-response reactions are the most basic sort of response. The stimulus is a change in the environment, and the response is how the organism responds to it.
A stimulation that comes from outside the organism is known as an external stimulus. Light is one example of an outside stimulation. Although it comes from outside the body, it has an impact there as well.
Thus, it can be concluded that light is an external stimulus.

the diagram shows two cells found in human blood.
a. the actual diagram of
red blood cell is 0.007mm ( 7 um) in diameter.
Calculate the magnification of the diagram. show your working.
side note: I measured it in a ruler and it's 2.3 cm = 23 mm (drawn to scale)
a)
Actual diameter = 0.007 mm
Diameter of scaled diagram = 2.3 cm = 23 mm
Formula to use:
Magnification = scaled dimension/actual dimension
Magnification = 23/0.007
Magnification = 3285.714... → x3286
b)
Red blood cells (RBCs), otherwise known as erythrocytes, don't have nuclei and organelles such as mitochondria, are smaller than WBCs and have a biconcave disc shape ideal for purpose
c)
i.
RBCs transport oxygen inhaled into the lungs around the body to all tissues and organs
ii.
RBCs are void of organelles so they are maximally packed with haemoglobin to bind and transport oxygen;
The biconcave disc shape is ideal for flowing through the blood vessels, particularly the capillaries, optimising them for transporting oxygen;
The small size also helps in being able to circulate the vasculature effectively and successfully

Which is true about water molecules?
A. Water molecules are nonpolar, meaning their charges balance each other out.
B. Water molecules are polar, meaning they have a net partial negative charge.
C. Water molecules are polar, meaning they have partial negative and positive
charges.
D. Water molecules are nonpolar, meaning they do not interact with each other.
Answer: C
Explanation: Water is a polar molecule because the electrons of the hydrogen atoms get "pulled" towards the electrons of the oxygen atom. Which is both positive and negative on opposite ends.
It could be B as well but, I believe it's C
Is the cholesterol molecule mostly polar or mostly nonpolar?
Answer:
Most of the cholesterol molecule in non-polar and therefore associations with the non-polar fatty acid tails of the phospholipids. However, the hydroxyl group (-OH) on cholesterol carries a negative charge and therefore associates with the polar environment of water either inside the cell or outside.
Explanation:

Answer:
Cholesterol is very non-polar, except for the hydroxyl group attached to the first ring.

The place where a group of organisms lives is called the ___________. The combination of the community and habitat is called the ___________.
Answer:
the first blank is biodiversity. I think like that
The place where a group of organisms lives is called the habitat. The combination of the community and habitat is called the ecosystem.
What is habitat and ecosystem?An ecosystem is basically the neighborhood where animal lives. The habitat is the animal's address in that neighborhood. Some animals can survive in more than one habitat. Other animals are limited to certain habitats. For example, moose habitat is more specific than gray squirrel habit.
Moreover, ecosystem is defined as the interrelationships between the biotic and abiotic component of the environment. Whereas habitat is defined as the natural environment in which a particular species of plants and animals lives.
Therefore, a habitat is a place where an organism makes its home. A habitat meets all the environmental conditions an organism needs to survive. For an animal, that means everything it needs to find and gather food, select a mate, and successfully reproduce.

Given that breaking bonds requires energy and forming bonds releases energy, explain how we know that cellular respiration releases energy overall?
because it's overall final fee energy value is less than it's initial, meaning that it has a negative free energy amount. therefore, there is a net release of energy in cellular respiration, so we know it releases more energy than it invests into the bonds of its products.
