Susan and Jake's truck gets stuck in the mud. They used a tree branch as a
lever toʻlift the truck out of the mud. They applied an effort force of 700N
to the branch and the back of the truck weighs 2100N. What is the
mechanical advantage of the tree branch lever?*

Answers

Answer 1

Answer:

3

Explanation:

MA = OF(output force) / IF (input force)                                         2100 N / 700 N = 3

OF=2100N

IF=700N

explain the importance of understanding the process of evolution.
why is it important to study how species evolve over the time and how does this relate to their changing environments?

Answers

Answer:

Knowing the evolutionary relationships among species allows scientists to choose appropriate organisms for the study of diseases, such as HIV. Scientists are even using the principles of natural selection to identify new drugs for detecting and treating diseases such as cancer. Environmental change and isolation of groups of organisms play an important role in evolution. Environmental change is any change in an environment to which an organism must adapt. Change can be gradual, such as when mountains or deserts form, other species die out, or new species evolve.

Given the discussion thus far of commensalism and parasitism, would parasitism be an accurate way to describe the relationship between the strangler fig and the cypress tree?

please help me

Answers

Yes, when two root tendrils from a strangler fig touch, they fuse together. Because the roots wrap around the trunk of the host tree, they overlap a lot and eventually form a mesh that completely encircles the host.
The “host” being a cypress tree.

The relationship between the strangler fig and the cypress tree closely resembles one of parasitism but is not. It is considered commensalism.

Parasitism is when one organism uses another as a host in order to survive, which generated negative impacts for the host, which will usually end in death. The strangler fig uses the tree as a host in order to sustain itself structurally but does not siphon nutrients from the tree or directly kill it, therefore it is not a form of parasitism.

Commensalism is described as a relationship between two organisms, in which the benefits are gained by only one of the members, but neither of the two is harmed in any way.

The relationship between the strangler fig and the cypress tree is best described as commensalism, given that although the strangler fig does eventually cause the tree to die by encircling its roots and not allowing it to grow, it does not kill the tree directly in order to survive.

-Enjoy your day!

Global warming affect biodiversity by increasing temperatures mean increased risk of extinction and the correct option is option B.

Global warming has a detrimental impact on biodiversity, primarily increasing the risk of extinction for many species. Rising temperatures disrupt habitats, leading to habitat loss and reduced living space.

Species may struggle to adapt or migrate fast enough to keep up with changing conditions, resulting in range shifts and potential mismatches in ecological interactions.

Additionally, the specific temperature tolerances of many organisms are exceeded, making them vulnerable to heat stress, disease, and other pressures. While some species may exhibit adaptive responses, the overall consequences of global warming on biodiversity are negative, posing significant threats to the intricate web of life on Earth.

Thus, the ideal selection is option B.

Gel electrophoresis can tell you the sequence of a particular DNA fragment.

Answers

True! All DNA molecules have the same amount of charge per mass. Because of this, gel electrophoresis of DNA fragments separates them based on size only. Using electrophoresis, we can see how many different DNA fragments are present in a sample and how large they are relative to one another.

Hope this helps!

The statement 'gel electrophoresis can tell you the sequence of a particular DNA fragment' is FALSE.

Gel electrophoresis is a technique widely used in molecular biology laboratories to separate DNA and proteins on the basis of their molecular sizes.

Gel electrophoresis consists in applying an electrical field through a gel that contains many small pores in which DNA fragments migrate.

The interval of time required for the migration of these fragments of DNA is proportional to the molecular size.

In conclusion, the statement 'gel electrophoresis can tell you the sequence of a particular DNA fragment' is FALSE.
