Answer:
B. an external force
Explanation:
Inertia can be defined as the tendency of an object or a body to continue in its state of motion or remain at rest unless acted upon by an external force.
In physics, Sir Isaac Newton's first law of motion is known as law of inertia and it states that, an object or a physical body in motion will continue in its state of motion at continuous velocity (the same speed and direction) or, if at rest, will remain at rest unless acted upon by an external force.
Hence, a secured object in an orbiting spacecraft remains at rest unless acted upon by an external force.
Which force produces a change in motion
Answer:
Unbalanced force
Explanation:
This force usually causes a change in motion, an example of this is when two forces act in the same direction of an object, the net forces equals the sum of two forces.

What novel characteristics are shared by gymnosperms and angiosperms but not by mosses and ferns?
Explanation:
Mosses go through sporophyte and gametophyte stages in their life cycle. ... However, mosses are nonvascular while ferns are vascular. Gymnosperms and angiosperms are both vascular, seed-bearing plants. However, gymnosperms release their seeds in cones (like pinecones) while angiosperms release their seeds through flowers.
What does an increased pulse rate indicate about the heart rate
Answer:
A high heart rate can also mean the heart muscle is weakened by a virus or some other problem that forces it to beat more often to pump enough blood to the rest of the body. Usually, though, a high heart beat is not due to heart disease, because a wide variety of noncardiac factors can speed the heart rate.
1. In your own words, what does it mean for a cell to be
specialized?
Answer:
A specialized cell means that even though they are similar, cells differ in size, shape or function depending on their role in our bodies. Each type of cell is modified to work in the way our bodies need it to. Specialized cell group together to form tissues.

A mother and father are curious about the possibility of having children of certain blood types. After some testing, the doctor tells them there is no chance that either of them will ever have a child with type O blood, no matter their partner. He does assure them that all of their children will have the same blood type. On the other hand, none of the children will have the same blood type as either the mother or the father. What blood type will the children be?
The blood type that the children won't have O blood type because the doctor says so and the children will not have the same blood type. This means that the children's blood type will likely be type A or Type B.
The graph shows the effect of pH on the rate of reaction to three different enzymes. What does the graph show?
Answer:
Regarding the effect of pH on the reaction rate of three different enzymes, what the graph shows is that each enzyme works better at different pH (option A).
Explanation:
Enzymes are specialized protein molecules whose function is to contribute to faster reactions with lower activation energy. To fulfill this function, enzymes must be in an optimal range of temperature and pH.
The graph shows three enzymes, one in an acidic medium, one in a neutral medium and one in a basic medium. The reaction rate of each enzyme is similar, indicating that each is working at an optimum pH. The best interpretation that can be drawn from the graph is that each enzyme works best at a different pH.
The other options are not correct because:
B. The variable "temperature" is not included in the graph.
C and D. Since the comparison of the reaction rate of a single enzyme at different pH is not being made, the graph is not useful to indicate whether an enzyme works better in acidic or basic conditions.

Describe: Fossil fuels are used in many ways. Using the Gizmo, describe the main use for each fuel.
Coal:
Petroleum:
Natural gas:
In each case, what is the end product of burning the fossil fuel, and where does it go?
Answer:
Coal:
Coal is primarily used as fuel to generate electric power
Petroleum:
heating and electricity generation, asphalt and road oil, and feedstocks for making the chemicals, plastics, and synthetic materials
Natural gas:
heating, cooking, and electricity generation.
it all end up in the atmosphere
Explanation:
The coal is burned and the heat given off is used to convert water into steam, which drives a turbine.
petroleum was formed from the remains of ancient marine organisms, such as plants, algae, and bacteria.
Like oil, natural gas is a product of decomposed organic matter, typically from ancient marine microorganisms, deposited over the past 550 million years. This organic material mixed with mud, silt, and sand on the sea floor, gradually becoming buried over time.
Coal and natural gas are burned in power plants to boil water. Steam from boiling water converts turbines into electricity. Carbon dioxide from burning fuel is released into the atmosphere.
This is about description of fossil fuels which are simply fuels that are formed from natural processes.
The uses and end products of fossil fuels are talked about in the explanations below;
1) (I) The primary use of the fossil fuel named coal is to generate electricity.ii) When coal is burnt, it produces a very high heat. This heat is so high that it converts water into high-pressure steam. What drives a turbine is a high pressure steam and this drive makes the turbine to produce electricity.
2) I) Petroleum products are used to set vehicles in motion, for asphalt on roads, production of electricity and heating of buildings.II) when petroleum is burnt to create energy, it produces high amount of carbon dioxide and other toxic gases into the atmosphere that can cause greenhouse effect.
3) I) Natural gas is used primarily as a source of energy for cooking, generating heat and for providing electricity.II) When it undergoes combustion is produces large amount of carbon dioxide and nitrogen oxides into the atmosphere.

In regard to actin(the thin filaments) and myosin (the thick filaments), how do
muscles contract?
The globular heads of myosin tie actin, framing cross-spans between the good and bad fibers. This development slides the actin fibers from the two sides of the sarcomere toward the M line, shortening the sarcomere and bringing about muscle withdrawal.
how does a birds digestive system work?ФΔФ
Answer:
Birds have a two part stomach, a glandular portion known as the proventriculus and a muscular portion known as the gizzard. Hydrochloric acid, mucus and a digestive enzyme, pepsin, are secreted by specialized cells in the proventriculus and starts the process of breaking down the structure of the food material.

Answer: Magnolia is a large genus of about 210 flowering plant species in the subfamily Magnolioideae of the family Magnoliaceae. It is named after French botanist Pierre Magnol. Magnolia is an ancient genus. Appearing before bees did, the flowers are theorized to have evolved to encourage pollination by beetles. To avoid damage from pollinating beetles, the carpels of Magnolia flowers are extremely tough. Fossilized specimens of M. acuminata have been found dating to 20 million years ago, and of plants identifiably belonging to the Magnoliaceae date to 95 million years ago. Another aspect of Magnolia considered to represent an ancestral state is that the flower bud is enclosed in a bract rather than in sepals; the perianth parts are undifferentiated and called tepals rather than distinct sepals and petals. Magnolia shares the tepal characteristic with several other flowering plants near the base of the flowering plant lineage such as Amborella and Nymphaea.

D. Offspring are genetically variable.
Answer:
c
Explanation:
i think im not sure
If an organism can reproduce asexually, its offspring are genetically identical to the parent.Therefore, the correct option is B.
What is asexual reproduction?Asexual reproduction is a mode of reproduction in which an organism produces offspring without the involvement of gametes or the fusion of genetic material from two parents.
Asexual reproduction involves only one parent, and the offspring are produced by mitotic cell division, which creates identical copies of the parent's DNA. As a result, asexual reproduction produces offspring that are genetically identical to the parent, and there is no mixing of genetic material from two parents as occurs in sexual reproduction.Therefore, the correct option is B.
