Answer:
D
Explanation:
Being permeable means that it is easy for liquids to pass through it. Liquids, being in this case water, passing through water fast and easy means that the soil is permeable
This is called a .............................................. reaction.
Ps. something to do with neurons
Due to the strong intermolecular force of attraction in cellulose it provides high strength and support.
Cellulose is a significant polysaccharide since it is the most copious natural compound on Earth. Cellulose is a significant segment of intense cell dividers that encompass plant cells, and it's what makes plant stems, leaves, and branches so solid. It absolutely takes a ton of effort to cause damage to the structure of cellulose.
Cellulose particles are arranged parallel to one another and are combined with hydrogen bonds. This structures long, link like structures, which join with other cellulose atoms and is the thing that produces such a solid help structure.
Answer:
I) For gametes formation
II) For pollen grain formation
III) For seed formation
Explanation:
The importance of meiosis are:
- gamete formation
During meiosis, sex cells such as sperms and ova are formed in the testes and ovary respectively
- pollen grain formation
Pollen grain are formed in the anthers of flowering plants
- Seed formation
Seeds also known as ovules, are formed in the ovary of flowering plants
b.conditions in an organisms environment ensure the organisms survival
c.birds and reptiles share a number of inherited characteristics
d. tigers are so different from cheetahs
Answer:
The correct answer would be c. birds and reptiles share a number of inherited characteristics.
In evolutionary biology, the principle of common ancestors or descent explains how different groups of organisms share a common ancestor.
In other words, different groups of organisms are believed to evolve from a common ancestor.
The groups which share recent common ancestor share a number of common inherited characters.
The groups which share distant common ancestor share less common characters.
Thus, birds and reptiles share a number of characters as they have evolved from common descent or ancestor.
Answer:
The correct answer is because of gravity and air resistance.
Explanation:
When we speak of free fall, we are referring to something that falls "into the void", and which has no force to oppose such a fall.
Due to the gravity and atmosphere of our planet, this situation is not possible. When an object falls close to our surface, it is very difficult to do it in free fall. Gravity is going to pull this object down, which along with air resistance, will cause the object to fall at a constant speed.
