a force has direction and contact true or false
Answer:
Because a force is a vector that has a direction, it is common to represent forces using diagrams in which a force is represented by an arrow. In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate. ... A force has both magnitude and direction, making it a vector quantity.
Therefore, yes
What can consumers do to make sure that more materials are recycled?
А buy products made from recycled materials
00
buy biodegradable plastics
С
use canvas bags when shopping
D
use paper bags instead of plastic bags
Answer:I feel like some of the answers for me would be A and B but if you only had to choose one I would choose A
Explanation: When you buy recycled you are helping the local economy and the environment. You already know that recycling keeps useful materials from going to waste in landfills or incinerators. But did you know that buying recycled-content products ensures that markets for those recovered materials are strong
Edit: Just figured out it's not B here's why:
Plastics marketed as "biodegradable" will contribute to plastic pollution if they are lost or littered. They do not break down as quickly and completely in the environment as the term might imply and thus can harm wildlife and ecosystems. Sorry if it's long
At the time when the consumers do to make sure that more materials are recycled so here option A is considered i.e. buy products made from recycled materials.
Recycled materials:At the time when we purchase the recycled so you helped the economy as well as the environment. Also, recycling plays a vital role for minimizing the wastage and make the proper utilization of the product.
Hence, At the time when the consumers do to make sure that more materials are recycled so here option A is considered i.e. buy products made from recycled materials.

Name the enzyme that breaks the hydrogen bonds holding the
two DNA strands together during DNA replication?
DNA helicase is the enzyme that breaks the hydrogen bonds which holds the two DNA strands together during DNA replication.
What is DNA helicase?During replication of DNA , the enzyme DNA helicase separates the two strands of DNA and causes the breakdown of hydrogen bonds between the two DNA strands which leads to separating of the DNA double helix into two individual strands which make easier to copy it.
In conclusion, DNA helicase is the enzyme that breaks the hydrogen bonds.

Which product of fermentation expands bread dough
Ethanol
Energy
Carbon dioxide
Carbon dioxide because During fermentation, carbon dioxide is produced and trapped as tiny pockets of air within the dough. This causes it to rise. During baking the carbon dioxide expands and causes the bread to rise further. The alcohol produced during fermentation evaporates during the bread baking process.

Explanation:
When humans come to a previously pristine environment, they inadvertently bring organisms with them that can be harmful to the local flora and fauna. Such organisms are known as _____.
Answer:
INVASIVE species
Explanation:
In biology, an organism is said to be INVASIVE if the organism is foreign to a particular region or habitat and possess the unpleasant ability to proliferate or grow rapidly to the point of competing with local species of organisms.
According to this question, humans are said to introduce organisms that have the ability to harm the local flora and fauna. Hence, these organisms are INVASIVE SPECIES because they are foreign to that place and cause damage in their new environment.

r If a mouse population changes color from white to black over many generations, which question should be asked to determine whether the population changes are a result of natural selection or artificial selection?
A.
What do humans need to keep mice healthy as pets?
B.
Was there a change in the genetic traits of the mice?
C.
Were the genes of the mice inherited from their parents?
D.
Was there a change in the environment where the mice live?
Answer:
D if there is a change in environment that would favor black fur you could assume that natural selection caused the fur to change
Explanation:
The question which should be asked to determine whether the population changes are a result of natural selection or artificial selection is that was there a change in the environment where the mice live? Thus, the correct option is D.
Natural selection is the process through which the populations of different living organisms adapt and change with respect to their surrounding environment. Individuals in a population are naturally variable, it means that they are all different in some way or the other. This variation in the population means that some individuals have traits which are better suited to the surrounding environment than others.
If a mouse population changes its color from white to black over many generations, then the question which should be asked is "Was there a change in the environment where the mice live?"
Therefore, the correct option is D.

Which of the following choices below represents an argument for the advantages of asexual reproduction?
A. Organisms that reproduce asexually are likely to find a mate at a faster rate than sexually reproducing organisms, which allows them to reproduce faster.
B. Organisms that reproduce asexually are more diverse and are more likely to pass on key genes for survival to future generations, which aids in maintaining beneficial genes for survival in the gene pool
C. Organisms that reproduce asexually gain variation through processes like crossing over, which allows survival in instances of ecological change
D. Organisms that reproduce asexually create a large amount of offspring in a short period of time in order to maintain their population
