What is the acceleration of.5-kg bowling ball when a 10-n force is applied
Answer:
The acceleration of ball is 2 m.s⁻²
Explanation:
Given data:
Mass of ball = 5 kg
Force applied = 10 N
Acceleration = ?
Solution:
Definition:
The acceleration is rate of change of velocity of an object with respect to time.
Formula:
a = Δv/Δt
a = acceleration
Δv = change in velocity
Δt = change in time
Units:
The unit of acceleration is m.s⁻².
Acceleration can also be determine through following formula,
F = m × a
a = F/m
a = 10 N / 5 kg
N = Kgm.s⁻²
a = 10 Kgm.s⁻² / 5 kg
a = 2 m.s⁻²

Choose a cellular function and make a claim about how structural features of the cell support the function. Use specific examples and details to support your claim.
Answer:
Cells have many structures inside of them called organelles. These organelles are like the organs in a human and they help the cell stay alive. Each organelle has it's own specific function to help the cell survive. The nucleus of a eukaryotic cell directs the cell's activities and stores DNA.

How are primary, secondary, and tertiary consumers different from each other?
What are autotrophs and heterotrophs?
Where does the energy in an ecosystem come from?
Answer:
Primary consumers are animals that eat primary producers; they are also called herbivores (plant-eaters). Secondary consumers eat primary consumers. They are carnivores (meat-eaters) and omnivores (animals that eat both animals and plants). Tertiary consumers eat secondary consumers.
Energy is transferred between organisms in food webs from producers to consumers. The energy is used by organisms to carry out complex tasks. The vast majority of energy that exists in food webs originates from the sun and is converted (transformed) into chemical energy by the process of photosynthesis in plants.
Summary. Autotrophs store chemical energy in carbohydrate food molecules they build themselves. Most autotrophs make their "food" through photosynthesis using the energy of the sun. Heterotrophs cannot make their own food, so they must eat or absorb it.

A tapeworm attaches to the wall of its host’s intestine and starts to absorb the host’s nutrients. Eventually this can cause great harm to the host as the host loses many important nutrients.
Which type of infectious agent is a tapeworm?
a virus
a bacterium
a fungus
a parasite
Answer:
A
because yes
Tapeworm is a parasitic infectious agent. Thus, the correct option is D.
What are Infectious agents?Infectious agents may be defined as those organisms that are competent in synthesizing infection or infectious disease in living entities. Examples of some infectious agents are bacteria, viruses, parasites, fungi, etc.
Tapeworm in humans is a parasitic-host relationship in which tapeworms are parasites and a human is a host. It is caused by the tapeworm species known as Taeniasis.
Therefore, the tapeworm is a parasitic infectious agent. Thus, the correct option is D.

List the 3 Parts of the Modern Cell Theory
Answer:
1. All organisms are made of cells
Cells are the smallest unit of life. Each cell is a membrane of semi-permeable phospholipids wrapped around cytosol or a solution of water and dissolved solutes. All cells rely on DNA to hold the information necessary to produce the molecules they use to obtain energy. Although the methods for obtaining energy vary widely, all organism obtain energy to grow and reproduce. This first tenet of the cell theory is mostly true, but the discovery of viruses lead to complications. Viruses, while they use DNA or RNA to reproduce, do not have cells or cellular membranes. Viruses typically use a host cell to replicate. In this case, the virus appears to be living, but does not create its own cell. Some scientist argue that viruses are not living, thus cell theory is not violated.
2. Cells are the most fundamental unit of life
Organisms can be single cells, which hold all of the components necessary for a metabolism, or they can be more complex. More complex organisms divide the various metabolic tasks into different groups of cells, called tissues. These tissues are arranged in compartments with membranes that separate them from other tissues. These groups of tissues are called organs. A group of organs functioning together is an organism, or an individual creature. Each cell is distinct from the cells next to it, and each functions independently, while contributing to the output of the organism as a whole. Again, modern cell theory is a bit more complicated because advances in science have revealed many different organelles within cells. These organelles are bound in membranes themselves, and serve different functions for eukaryotic cells. Some scientists argue that these are more fundamental units, but other scientists argue that like an organ outside of an organism, they could not function without the cell.
3. Cells come from other cells
As far as we know, no cell on Earth currently has arisen spontaneously. All cells are the result of cell division. When a cell is large enough, it replicates its DNA and important components. These components can then be divided into two daughter cells, which are copies of each other. Variations in the DNA in each cell can lead to changes in how they function, which can result in them dividing at different rates. The cell that reproduces more than the other cell will pass on more of its DNA. The purpose of every cell or organism is to reproduce the DNA in cells.
This third tenet of the cell theory has yet to be disproven. No scientist has ever created a functioning cell without replicating another cell, although some scientists are trying. If they were successful, it would give proof to how life could have evolved. It is thought that a self-replicating molecule mutated, developed the ability to produce a membrane, and thus the first cell was born. The cell was such a successful form of life that all life since has used the same basic template.
The parts of the modern cell theory are:
All living things are made up of at least one cellCell is the basic and fundamental unit of lifeAll cells arise from pre-existing cellsCELL THEORY:
Cell theory is a universally accepted theory that explains the features of life in three statements.The cell theory was composed in 1890's by three scientists namely: Rudolf Virchow, Mathias Scleiden and Theodor Schwann.

When and where would the number of daylight hours each day be the greatest?
A during the winter near the equator
B during the summer near the equator
C during the winter near the North Pole
D during the summer near the north pole.
Answer:
D. during the summer near the North Pole
Explanation:
The angle of the sun above Earth's Northern Hemisphere is greatest on this day. Because Earth is tilted toward the sun to the maximum degree, the North Pole has 24 hours of daylight on June 20 or 21, whereas the South Pole (which is tilted away from the sun to the maximum degree) has 24 hours of darkness.

Natural resources are used to create synthetic materials.
Synthetic materials are created by chemically altering the starting substances to produce a material with distinct properties.
What is the importance of synthetic materials?The elasticity of synthetic fibers is excellent. They are not easily wrinkled. Fabrics made from these fibers are less expensive, more durable, and more widely available than natural fibers. Synthetic fibers can withstand high loads without breaking.A variety of advantages are provided by synthetic materials. They may be less expensive to produce than natural materials, and they may also perform better. However, synthetic materials pollute the environment more than natural materials, and they can sometimes be harmful to our health.To learn more about : Synthetic materials
