Now Thomas Roberts of Oregon State University in Corvallis and Richard Marsh of Northeastern University in Boston propose that frogs maximise their muscle power by storing energy in some elastic structure just before they become airborne. The researchers filmed bullfrogs jumping and used a computer model to calculate the energies required to produce such leaps. They found that the numbers only add up if the frogs’ contracting leg muscles also stretch a tendon-like component. When released, like the elastic in a slingshot, the energy stored in the tendon helps fire the animal into the air

A student used poster board to construct this model of DNA.Which statement describes this model of DNA?

pantera1 [17]

Answer:

The model is inaccurate because the base pairs are incorrect.

Explanation:

The model of DNA that the student made was:

G-G

A-A

T-T

C-C

G-G

A-A

T-T

C-C

The model is pairing the bases incorrectly since guanine (G) forms a base pair with cytosine (C) and adenine (A) with thymine (T). In other words, the bases do not pair with the same type.

The DNA strands, which have deoxyribose, phosphate groups, and different bases, are together thanks to hydrogen bonds between the pairs. The pair G-C has three hydrogen bonds, while the pair A-T has two hydrogen bonds.

Living organisms are only able to function and thrive if they can maintain constant or stable internal conditions. This ability

Hatshy [7]

The ability of organisms to regulate and thus maintain a relatively stable internal environment, despite external pressures, is called HOMEOSTASIS. This word comes from two Latin/Greek root words: "homeo" and "stasis".
"Homeo" means constant or unchanging. And "stasis" or "static" refers to stillness, non-movement. So, together, we can translate Homeostasis into a constant stillness inside, which makes sense for "maintaining normal internal states."

What do the limiting factors actually limit?

Tasya [4]

Limiting factors are resources or other factors in the environment that can lower the population growth rate. Limiting factors include a low food supply and lack of space. Limiting factors can lower birth rates, increase death rates, or lead to emigration.
