Earth is unique in the solar system because it has a relatively stable and mild (blank)
Alexandra [31]

Several conditions make our planet earth unique, to answer this statement we need to understand that.....

<h3>Earth is unique</h3>

There are many planets in the solar system, however, none have a location like planet Earth. Our planet is in a privileged condition, as it is located at a distance from the sun that does not prevent the emergence of elements essential for sustaining life, that is to say, it is not very close, a fact that would raise temperatures, and very far away, when they would be very low, hindering the development of lives.  This factor was decisive for the formation of liquid water on planet Earth, since it is the only one with such a resource in the solar system.

With this information we can come to the conclusion that the statement is <u>correct,</u> the stability of the earth and location in the solar system, provided that the earth could have water in a liquid state.

How do enzymes act as catalysts to help maintain homeostasis for the cell.
Alenkasestr [34]
Enzymes are the things in our bodies that facilitates reactions.  They break down bonds in carbohydrates, lipids and proteins.  When the food is being broken down, it is easier for the body to use.  When the body is conducting cellular respiration, it uses monosaccharides (singular carbohydrate), to form ATP which is useable energy for the body.  The body uses ATP everywhere for all bodily functions, which maintains homeostasis. <span />

Draw a picture of DNA replication. Label the direction each strand is going, the enzymes involved with each step, the leading an
Step2247 [10]

Answer:

The fork is drawn to emphasize its similarity to the bacterial replication fork depicted in Figure. Although both forks use the same basic components, the mammalian fork differs in at least two important respects.

First, it uses two different DNA polymerases on the lagging strand.

Second, the mammalian DNA primase is a subunit of one of the lagging-strand DNA polymerases, DNA polymerase α, while that of bacteria is associated with a DNA helicase in the primosome. The polymerase α (with its associated primase) begins chains with RNA, extends them with DNA, and then hands the chains over to the second polymerase (δ), which elongates them. It is not known why eucaryotic DNA replication requires two different polymerases on the lagging strand. The major mammalian DNA helicase seems to be based on a ring formed from six different Mcm proteins; this ring may move along the leading strand, rather than along the lagging-strand template shown here.

Bas_tet [7]

Answer:

mtDNA is used, consider forensic laboratories to characterize bone remains and identify individuals who have other evidence

The disadvantage of using mtDNA in relation to nuclear DNA is that it does not identify individuals unambiguously, it only detects relationships between groups of individuals
