In beetles, the gene for color and the gene for pattern are located on the same chromosome and exhibit recombination. The lined

pattern allele (l) is recessive to the solid unpatterned allele (L), and the aqua color allele (b) is recessive to the blue color allele (B). Geneticists cross a homozygous lined aqua beetle with a homozygous solid blue beetle. Then, they carry out a testcross using the F1 progeny. The parental chromosomes for the testcross are given. Identify all possible gametic haplotypes each parent can form.

Answer and Explanation: First cross is between homozygous: LLBB x llbb.

Homozygous individuals produce one type of gamete:

  • For homozygous dominant is <u>LB</u>
  • For homozygous recessive is <u>lb</u>

So, F1 progeny will have genotype : LlBb

Second cross is between the F1 progeny in a testcross. A testcross is a genetic cross between a homozygous recessive individual and a suspective heterozygous genotype to determine the latter.

So, second cross is: LlBb x llbb

As said before, homozygous will produce only one type of gamete: <u>lb</u>

For heterozygous individuals, and one that exhibits recombination, will produce 4 types of gametes:

  • <u>LB</u> : parental
  • <u>lb</u> : parental
  • <u>Lb</u> : recombinant
  • <u>lB</u> : recombinant

Which energy source did you rank as the worst option for the rescue team
stellarik [79]

Answer:

The worst option of energy source for the rescue team would be - nuclear, hydroelectric, combustion and fuel burning all are worst option fro max to less worst.

Explanation:

The best option for the energy source for the rescue team would be hand canker, lever as it is mechanical energy generator does not require anything but hand movement to generate energy to charge equipment and easily carry  anywhere.

Solar, wind energy are also helpful for rescue team but nuclear energy, hydropower, fuel burning energy source are risky, not handy and costly options.

Thus, the worst option are-  nuclear, hydroelectric, combustion and fuel burning energy source.

you are a molecule of carbon. choose a starting point in the carbon cycle and describe the process you would go through to move
Assoli18 [71]
Answer:

1) start as a carbon molecule in the atmosphere
2) taken in by trees through photosynthesis
3) carbon is taken into decayed organism
4) then it is taken into dead organisms and waste products underground
5) millions of years later, it is stored in a fossil
6) fossil fuels used by factories then emit carbon dioxide back into the atmosphere (back to starting position

if you want the whole cycle then..
7) used again by a tree
8) released as organic carbon (some)
9) tree leaf is eaten by an animal, which then releases carbon either from respiration or when it dies

A botanist has discovered a new plant species and is trying to classify the plant. Its seed has one cotyledon, it has six flower
lana66690 [7]

The best suited group for the mentioned plant is Angiosperms and monocot.

Answer: Option C

<u>Explanation:</u>

As mentioned the seed of the plant has one cotyledon and the specific name for these type of plants whose seeds has one cotyledon is called Monocot, Suppose if the seed of the plant has two seeds, It is called dicot.

Hence we can conclude that the mentioned plant comes under monocot and not dicot.  On the other hand, Angiosperms refers to the plants that has flowers with it and gymnosperms usually includes plants without flowers and hence we can classify the plant as Angiosperm and monocot.

The three dimensional folding shape of a prion is probably most determined by
Vlad [161]
Prions are infectious agents that are made up of proteins which can fold in multiple ways. The three dimensional folding shape of a prion is determined by folding and intra molecular bonding of the linear amino acid chain. The folding and the intra molecular bonding on the other hand is determined by the amino acid sequence in the prion.
