<h3><u>Answer;</u></h3>
acceleration= 2 m/s²
<h3><u>Explanation;</u></h3>
From the second Newton's Law of motion the resultant force is directly proportional to the rate of change in momentum.
That is;
F = ma
Thus; F = 100 N, m = 50 kg
a = F/m
= 100/50
= 2 m/s²
Answer:
Yes, different cell types also have special duties, like building skin or bone, pumping out hormones, or making anti-bodies.
Explanation:
Cell is the basis structural and functional unit of a living organism. The body of a human is composed of trillions of cells that are organized in around 200 types of cells.
<u>A tissue is simply a group of specific kind of cell that have a specific role.</u>
- For example: The nervous system contains cells called neurons that have ability to transmit message from one place to another and allow us to respond to any environmental stimuli, such as heat, cold, danger etc.
- Skin cell is composed of cells that have a role in protecting the body against the attack of harmful microbes. They also protect have role in building new skin cells and adding the protection to our body.
- Blood cells have a role in providing us immunity (for example white blood cells) therefore, make us better able to protect ourselves from danger of diseases.
- Muscle cells help us in moving our organs as well as allowing the whole movement from one place to another.
Thus we see that different types of cells have special functions and all these different cells coordinate with each other to make an organized and functioning body of a living organism.

I was sitting in my room, my eyes glued to the flashing screen, the palm of my hands slick with sweat as I struggled to hold onto the controller, the smooth surface slipping every second or so. I could barely hear anything, but the blaring of the sound effects that blasted through my room, shutting out any sound, including the knock on my door from my mother. I started, dropping the controller, my eyes wide. I snapped "What!" at my mother, her face contorting into pinched irritation. "Dinner is ready." She said, turning away to head back down the stairs. My eyes shifted to the open doorway, the nostrils of my nose flaring as I took in the scent of food. I could smell spices, and the humid stench of steam. My stomach growled and I quickly shot up from the floor and thundered down the stairs, leaping into the kitchen to find the source of the heavenly smells that wafted in my direction. I spotted turkey, garnished with lemon and green herbs, and sitting beside it, a large bowl of something off-white. It looked like mashed potatoes. I hastily took a seat and set my elbows upon the wooden surface of the table, my mother scolding me over her shoulder as she divided place settings. "Elbows off, please." She piped, pulling out her own chair with an ear splintering squeal that grated my nerves, causing my teeth to grind together. My mother passed a plate of green beans towards me, and I quickly scooped them onto my own plate, then going for the turkey, the mashed potatoes added last. With no time for prayer, I dug in, the tinges of my fork scraping against the plates clay surface as I scooped a fork full of beans up, and shoved it into my mouth. It tasted bland, with the barest hint of salt. I swallowed, cringing as it went down and took a bite of the mashed potatoes. Of course it was delicious. They were light, buttered perfectly. I gave a small sound of appreciation and went for the turkey last. I stabbed a piece of meat and popped it into my mouth, the texture odd. Hard to describe really. It was tough, but also soft enough to bite into, and with lemon added into it, it was tangy, making my mouth salivate. My mom smiled at the expression my face, nearly laughing. I made a face at her and swallowed, going in for another bite.
