Complementary strand of DNA? DNA Strand 1: AATCGGTAC

lesantik [10]

Answer:

TTAGCCATG

Explanation:

Deoxyribonucleic acid (DNA) is a double helix molecule made up of two complementary polynucleotide strands oriented antiparallel to each other. Each nucleotide in both DNA strands is composed of a five-carbon sugar (deoxyribose), a phosphate group and a nitrogenous base. In DNA, there are four types of nitrogenous bases: Thymine, Guanine, Adenine and Cytosine (in RNA, Uracil replace Thymine). According to the base-pairing rules, Adenine always pairs with Thymine through two hydrogen bonds, whereas Guanine always pairs with Cytosine through three hydrogen bonds.

Compare and contrast the processes that form different fossil types

marishachu [46]

<h3>Processes that form different fossil types:</h3>

The remained parts and elements of an organism that live several years ago is called as fossils.

Due to natural processes like weathering, soil erosion and other geological activities fossils are hard to preserve.

Carbonization, permineralization, recrystallization and replacement are the fossil formation processes.

Carbonization is the chemical reaction forming the thin film of carbon of the organic material.

Permineralization includes the fossils of bones and teeth. The recrystallization process is responsible for changing the micro-structure of the organic materials to form the fossils.

Use the codon chart to convert this sequence into an amino acid: UCU-CGA-GCC-GUU-GGG-UGA

RUDIKE [14]

The answer is Ser-Arg-Ala-Val-Gly-STOP

It is known that three nucleotide bases on mRNA are called codon and that each codon codes for the specific amino acid. According to the genetic code chart, the following mRNA sequence will code for the following amino acid sequence:

mRNA sequence: UCU CGA GCC GUU GGG UGA

Amino acid sequence: Ser Arg Ala Val Gly STOP

Where do queen bees lay eggs and larval bees are fed by worker bees

steposvetlana [31]

Answer:

1. Queen bees lay their eggs after within each cell inside a honeycomb.

2. True. Worker bees feed the larvae with a combination of nutrients, from nectar and pollen to bee milk and water.

Explanation:

1. Queen bees lay their eggs after within each cell inside a honeycomb (hive) [See image below] during the winter.

The queen is able to lay over two thousand eggs PER DAY! Each egg has an approximate size of 1 mm long. This process then leads to the formation of a whole new colony of bees.

2. True.

Worker bees have the largest density of all, that is, there are numerous worker bees within a colony. As their name "worker" implies, they have plenty of tasks to perform. For example, they have to clean the hive regularly, ventilate it during warm conditions or keep it warm during cold conditions, and also care for the queen. However, one the most important roles of workers is to feed the larvae, during this stage they are also called "nurse bees." These bees feed the young with a combination of nutrients, from nectar and pollen to bee milk and water.
