Seeds have cotyledons from where they can draw their nutrient in their early stages of development. Pollens must draw their nutrient from their environment from the start.
Seeds have an outer coating (testa) that protects the embryo and enable it to remain dormant in the soil until right conditions for growth set forth
Seeds have a fully developed embryo that can begin to grow immediately there are right conditions. However, pollen has a single cell instead of an embryo, which must undertake cell division and specialization before beginning to germinate
One way is runoff, I forgot the other
Correct answer: D). If an object's velocity is changing, it's either experiencing acceleration or deceleration
Acceleration can be defined as the rate of change of velocity of an object with respect to time. It is the result of all the forces, which are acting on the body. It can be calculated by dividing the change in velocity with the change in time.
If the velocity of an object is increasing it means the object is in motion and if it is decreasing it shows that the object is experiencing deceleration.
Answer:
- prehensile hands and feet
- five digits and opposable thumbs
- flexible and limber shoulders and hips
- big and complex brains
Explanation:
The primates are the most intelligent animals collectively, and they include the most intelligent animal on the planet, the human. All of them share some common characteristics that lead the paleoanthropology to conclude that they share a common ancestor. Most of them have prehensile hands and feet, which is a rare among other groups of animals. Almost all of them have five digits on their hands and feet, possessing opposible thumbs as well, enabling them to grab things. The shoulders and hips are also much different than the other animals, being much more flexible and limber. The most important characteristic maybe is their brain, as it is abnormally large and complex when compared with other animals of the same sizes. Their complex brains enable them to perform numerous things that other animals can't even imagine, and eventually that large brain helped in creating the most intelligent animal on the planet, the human.
Answer:
C. <em>Clostridium</em> and <em>Bacillus</em>.
Explanation:
<em>Bacillus </em>and <em>Clostridium</em> are the gram-positive bacteria and form endospores. Endospores are the resistant dormant structures formed by some gram-positive bacteria.
These bacteria form the endospores within their vegetative cells. The endospores are highly resistant to environmental stress conditions and make these bacterial genera the dangerous pathogens.
