What is the other main type of chemical bond?
Answer:
Explanation:
Answer:
answer (UNDER)
Explanation:
Chemical bonds include covalent, polar covalent, and ionic bonds. Atoms with relatively similar electronegativities share electrons between them and are connected by covalent bonds. Atoms with large differences in electronegativity transfer electrons to form ions. The ions then are attracted to each other.

Chemical weathering occurs by which of the following:
heat
oxidation
hydrolysis
dissolution
water
wind
Solution, carbonation, hydration, oxidation, and reduction are significant chemical weathering reactions, hence options B and C are correct.
What is chemical weathering?Chemical weathering is the term used to explain how chemicals in rainfall alter the minerals in a rock. Rainwater becomes somewhat acidic as a result of the air's carbon dioxide being dissolved in it.
Weathering can result from an interaction between the minerals in the rock and precipitation.
Oxidation, hydrolysis, and carbonation are processes that take place during chemical weathering.
Therefore, hydrolysis is a reaction with water, carbonation is a reaction with CO₂ to generate a carbonate, and oxidation is a reaction with oxygen to form an oxide, hence options B and C are correct.

Green seed color (G) is dominant over yellow seed color (g). If two heterozygous parents are crossed, what are the resulting phenotypes expressed as a percent?
A) 50% green, 50% yellow
B) 75% green, 25% yellow
C) 50% GG, 50% gg
D) 25% GG, 50% Gg, 25% gg
E) none of the above
Answer:
B) 75% green, 25% yellow
Explanation:
There are three genotypes made from crossing two heterozygous parents (Gg);
GG
Gg
gg
Crossing two heterozygous parents (Gg) results in 50% Gg, 25% GG and 25% gg. Since green (G) is dominant over yellow (g), there would be a total of 75% green and 25% yellow.

The finches that darwin studied differed in the shape of their beaks. according to darwin, which of these best describes these finches?
Answer:
C
Explanation:
A. no... the finches were living in different environments making them become less similar over time.
B. no... the Galapagos are long way from Africa... not possible
C. yes... This is true ... the size and shape of the beaks makes a big difference in the type of food the finches could eat. Seed types would change as climate change and finches would with the best beak size for the food available would survive.
D. no very unlikely. DNA Evidence show that the finches were from one common ancestor
The finches that Darwin studied differed in the shape of their beaks. According to darwin it become adapted to eating different foods.
Support your answer?The size and shape of the beaks make a big difference in the type of food the finches could eat.
Seed types would change with climate change and finches would with the best beak size for the food available to survive.
Thus, option "C" is correct whereas another option is very unlikely DNA Evidence shows that the finches were from one common ancestor.

A student makes a new gel using agarose, water, and buffer solution. The student loads their DNA samples in their wells and places the gel in the chamber for an appropriate length of time. When the student places the gel on the UV lightbox, no DNA bands show up at all. Even the marker lane is clear and has no bands! What mistake did the student make? Explain your answer.
Answer:
A dye needs to be added to the gel electrophoresis
Explanation:
Ethidium bromide (EtBr) is a reagent that adheres to DNA and fluoresces under ultraviolet (UV) light. Due to this feature, EtBr is widely used to dye DNA strands in molecular biology techniques such as agarose gel electrophoresis. The most common dyes for visualizing and staining nucleic acids during gel electrophoresis include EtBr, SYBR gold, Eva green and SYBR safe. If EtBr (or any other staining agent) was not added to the electrophoresis gel and/or running buffer, the gel will be dark under UV light (even the ladder lane will look empty) because DNA has not been stained.
The mistake the student made was by not adding dye to the sample. Dyes
are commonly used during electrophoresis.
Agarose gel electrophoresis is the process which helps in the separation
and purification of DNA samples. This process involves the use of dyes
which acts as markers.
in this scenario, we were told no DNA bands show up and the marker lane is
clear means no dye was added. The common dye used in agarose gel
electrophoresis is Ethidium bromide (EtBr) which should be added by the
student.

Explanation:
Which is the preserved evidence of the activity of an organism a) cast b) mold c) fossil film d) trace fossil
Answer:
fossil film
Explanation:
A carbonaceous film or carbon film is an organism outline of a fossil. It is a type of fossil found in any rock when organic material is compressed, leaving only a carbon residue or film. ... Fossils usually form when sediment buries a dead organism.
The preserved evidence of the activity of an organism is trace fossil. The correct option is d.
What is trace fossil?Animal behavior is what creates a trace fossil. A trace fossil might be something like a dinosaur footprint or an arthropod burrow. Beetles' pre-fossilization burrows can be seen as holes in this petrified wood.
When an organism leaves an impression in mud or sand, a trace fossil is created. Sediment dries out and becomes harder.
A fresh sediment layer has been added on top of it. The remnant fossilizes as the sediment hardens into rock as a result of cementation and compaction.
Body fossils are the hard parts of an individual creature or plant that have been preserved over time. Trace fossils are the best-preserved examples of an organism's past activity.
Thus, the correct option is d.
