Answer:
The hydrophobic core of the membrane does not allow the charged particles to pass through it.
Explanation:
The inner core of the membrane is made up of hydrophobic fatty acid tails of phospholipids. Due to this, some substances such as large, charged and polar particles cannot cross the membrane. This is why Na+ with a positive charge cross the membrane with the help of transport proteins only. On the other hand, molecular oxygen (O2) has a small structure and does not carry any charge. Therefore, it can cross the membrane without any help of transport proteins.
Answer:

- The difference between a rock and a boulder can be explained in terms of size and detachment. A rock is defined by geologists as an aggregate of minerals. A boulder is a type of rock, specifically a large detached one. All boulders are rocks, but not all rocks are boulders.

I'm sorry if this is wrong but after doing some research for this I only found that granite and large boulders are considered rocks. And again I'm sorry if this is wrong, and sorry that this response is late.,.
Edit: Can you tell me if the answers is wrong? you don't have to tho.
Answer:
<em>Small teeth will be missing. </em>
Explanation:
As seen from the information of the question, that dogs having medium and long teeth will not carry any alleles for small teeth. So, if a certain viral disease eradicates all the dogs with small teeth, there will be no organisms left to carry genes for this trait. Over time, the medium teeth dogs and long teeth dogs will be more adapted to the environment. Hence, after 10 generations no small teeth dogs will be seen.
Selective breeding is breeding between two animals of similar characteristics. cross breeding occurs when two animals from the same species create a new breed. such as when a husky and wolf have a puppy. they are the same species but different breeds.
Answer: Option E. "toxoplasmosis"
Explanation:
Toxoplasmosis is a disease caused from infection with the parasite "Toxoplasma gondii". It can occur due to eating undercooked contaminated meat, from mother-to-child during pregnancy or exposure from infected cat feces.
Toxoplasmosis is said as one of the major problem for AIDS patients that is caused by reactivation of a chronic infection. It generally targets to the brain (encephalitis) and the the eyes.
The common symptoms of toxoplasmosis involves swollen lymph nodes, headaches, fatigue, and fever.
Thus the correct option is E.
