Nady [450]

Each daughter cell carries exactly one half of the genetic material from the mother cell. In females the result of meiosis is the production of egg cells, where in the male, the result of meiosis is the production of sperm cells.

The concept of endosymbiosis (chloroplast & mitochondria) is widely accepted. What kind of relationship is it?
melamori03 [73]

Answer:

mutualistic

Explanation:

The interaction between two organisms in which both the organism gets benefitted from each other is called a mutualistic relationship. This mutualistic relationship is seen in the concept of endosymbiosis.

According to the endosymbiotic theory chloroplast and mitochondria are evolved by engulfment of different bacteria by ancestral cells. Then these bacterial remained in a mutualistic relationship with each other and the ancestral cell evolved into a eukaryotic cell.

So as mitochondria and chloroplast live with a symbiotic relationship with eukaryotic cells, therefore, it is considered as mutualistic relationship.

A driver traveling at a speed of 21 m/s tops a hill and spots a deer standing in the middle of the road 90 meters away. He hits
Iteru [2.4K]

Answer:

84m

Explanation:

Using the kinematics equation we can come up with the answer:

d=\dfrac{Vf+Vi}{2}\times t

Where:

Vf = final velocity

Vi = initial velocity

t = time

In your problem we have the following given:

Vf= 0 m/s

Vi = 21 m/s

t = 8 seconds

The Vf is zero because the car stopped. The distance given in this case is not useful in determining the car's distance so we will solve it. So just fill in the equation with the given:

d=\dfrac{Vf+Vi}{2}\times t\\\\d=\dfrac{0m/s+21m/s}{2}\times 8s\\\\d=10.5m/s\times 8s=84m

Thankfully, the deer was not hit!
