Two nucleotides on the same strand form a <u>Phosphodiester bond </u>while two complimentary bases on opposite strands form <u>Hydrogen bonds</u>. An a-t base pairing forms <u>2</u> such bonds.

The constituent components that make up DNA's double-helix structure are known as nucleotides. Each nucleotide has a base in it. The four various colors you see here stand for the four different bases that might be used. Between nucleotides, a unique kind of covalent link known as a phosphodiester bond occurs. The two strands of DNA are formed by these phosphodiester linkages.

Hydrogen bonds are the bonds that develop between base pairs. Thymine and adenine make two hydrogen bonds, and guanine and cytosine form three hydrogen bonds. Therefore, we have concluded that hydrogen bonds are the type of binding that develops between base pairs in DNA to hold the two strands of a double helix together.

Fdsci 101 what general trend do you observe relative to the masses of these species? question 3 options: all species basically h
Alexandra [31]

The third and last option is correct.


Species in the past (referring to dinosaurs) were more massive.

\bf~CO_{2} levels where higher in the past, which meant that plants prospered during that time since they had a easy access to food. That contributes to the fact that herbivores could grow bigger because there was more food. Which in turn, increases the size of early carnivores which eat bigger herbivores.




Hope it helped,


Happy homework/ study/ exam!

How could the tomato plants response to being eaten by a hornworm caterpillar be described as a function of homeostasis
sesenic [268]

Answer:

First, it's important to get clear on the meaning of Homeostasis.

In simple terms, it refers to the capacity of a living thing (plant or animal) to react or behave in such a way that enables it to continue to survive irrespective of changes in its immediate environment.

       

Explanation:

In humans, the body has a system which reacts to the external stimuli of temprature. When the weather is hot, the brain through a sequence of electrical and chemical signals tells the skin to open up the pore, then we experience venting of sweating which cools the body and regulates internal heat. This is an instance of homeostasis.

This does not mean that the plant or animal is completely immune to such external changes.

In the case of the tomato plant, the hair on the leaves and stem of the plant is an example of Homeostatic responses which have evolved over the years to discourage predators such as the hornworm caterpillar from defoliating the plant.

Cheers!

An exocrine gland that has an unbranched duct would be classified as a __________.
Firdavs [7]

Answer:

B) Multicellular Simple gland

Explanation:

Exocrine Glands:Glands that secrete their products onto the apical(or epithelia) surface directly or via epithelial ducts or tubes that are connected to the apical surface. These Exocrine glands are composed of highly specialized epithelial cells..

Exocrine glands can either be branched or Unbranched based on the arrangement.

*Multicellular simple glands*:Glands that have an *unbranched duct* into which cells secrete. Each secretory portion empties separately on an epithelial surface.
