When a pinecone is open, it disperses its seeds. Based on your experiment, can you tell what weather conditions are needed for pine trees to release their seeds? Explain your answer.

Answers

Answer:

If a pine seed finds the right micro-climate, it will eventually sprout and a pine seedling will start to grow. However, pine seeds are usually released in a dormant state, which is most often broken by cold stratification. As a result, a pine seed will not sprout until the following spring when warm weather and some spring moisture are present.

If your body is capable of making only certain amino acids, how do we get the essential amino acids we need?

Answers

Answer:

Essential amino acids cannot be made by the body. As a result, they must come from food. The 9 essential amino acids are: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.

Explanation:

Essential amino acids are available to the body through diet.

What are amino acids?

Amino acids are the key units in protein formation. They are the building blocks in determining protein structure.

Amino acids are amphoteric molecules which means that they contain dual functional group - amino and carboxylic acid.

There are twenty different amino acids present. Amino acids are classified into four main groups:

Non polar amino acidsPolar but charged amino acidsNegatively charged amino acidsPositively charged amino acids

Amino acids are crucial in the determination of genetic code. They are also important in transcription and translation process.

Amino acids are joined together in large number and form polypetides through peptide bond formation.

Based on the nutritional requirements amino acids are classified into two types:

Essential amino acids - amino acids which cannot be synthesized by the body and thus need supplementation through diet.Non essential amino acids - amino acids which can be synthesized by the body.

Therefore, amino acids are important in the biochemistry of proteins and several biochemical processes.

What do codons in DNA code for?

Answers

Answer:

mRNA and then amino acids

Explanation:

Codons are triplets (3) bases that code for defined amino acid sequences.

DNA is transcribed into mRNA. The mRNA codons are then translated into amino acid chains that form proteins.

Each codon codes for an amino acid, which is brought to the growing polypeptide chain by tRNAs via complementary base pairing.

Which statement about the structure of organic molecules is true
1. DNA contains fatty acid chain
2. Lipids are composed of Amino acids
3. Proteins are composed of nucleotides
4. Carbohydrates contain monosaccharide units

Answers

Answer: The answer is D

Explanation:

The statement which is true about the structure of organic molecules is as follows:

Carbohydrates contain monosaccharide units.

Thus, the correct option for this question is D.

What do you mean by Organic molecules?

Organic molecules may be defined as those molecules that are correspondingly made of carbon and hydrogen. It can also include other elements like oxygen, sulfur, nitrogen, etc. It must contain carbon atoms covalently bonded to hydrogen atoms (C-H bonds).

DNA possesses monomeric units known as nucleotides. Lipids are the derivatives of fatty acids. While proteins are composed of building blocks that are known as amino acids.

On the other hand, carbohydrates are derived from monosaccharide units that are togetherly held by glycosidic linkage.

Therefore, carbohydrates contain monosaccharide units is a statement that is true about the structure of organic molecules. Thus, the correct option for this question is D.

Which of the following can occur because of the exchange of homologous chromosome parts during the process of meiosis?

Answers

Answer:

Muttation can occur during the exchange of genetic meterial from homologous chromosomes which may led to cause deseases in some cases.

Explanation:

Homologous chromosomes exchange genetic material during the process of meiosis.

What is Meiosis?

Meiosis is a type of cell division in which germ cells present in the sexually-reproducing organisms produces the gametes, such as sperm or egg cells. It involves two rounds of division which results in four cells with only one copy of each chromosome.

These four cells are haploid in nature. Meiosis produces the sex cells or gametes like eggs in females and sperm in males.

Meiosis is divided into nine stages. These are divided between the first time the cell divides (meiosis I) and the second time it divides (meiosis II).

Thus, homologous chromosomes exchange genetic material during the process of meiosis.
