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.

What is mitosis?Mitosis is a type of cell division method that occurs in all the somatic cells and plays a crucial role in living organisms. They produce daughter cells to increase the cell number and to aid in the growth and development.
They replace and repair the damaged cells in the body and also is a form of asexual reproduction where the parent cell is divided to form a new daughter cell with the same ploidy.

1. How much force accelerate a bicycle and rider with mass 60 kg at 1.5 m/s?
Answers
Answer:
Force, F = 90 N
Explanation:
Given that,
Mass of the bicycle and rider, m = 60 kg
Acceleration of the bicycle and rider, a = 1.5 m/s²
We need to find the force acting on the bicycle and rider to accelerate. Let it is F. Its force is given by :
F = ma
F = 60 kg × 1.5 m/s²
F = 90 N
So, the force acting on the bicycle and rider is 90 N.

Every winter, Alice notices that the monarch butterflies seem to disappear from her backyard garden. Then, the butterflies return to her garden each spring. Which best describes the butterflies' behavior? migration, which is a response to an external stimulus migration, which is a response to an internal stimulus flight, which is a response to an external stimulus flight, which is a response to an internal stimulus
Answers
Answer:
migration, which is a response to an external stimulus
Explanation:
The butterflies were migrating in response to external stimuli.
Migration is the movement of organisms from one place to another in response to external stimuli. The stimuli could be for food, shelter, weather, etc.
Flight in response to external stimuli is often due to the presence of danger as stimuli. The adrenal gland releases epinephrine which triggers physiological changes in the body and makes the organism decide whether to run, stay, or fight.
In this case, the butterfly could have been migrating in response to the availability of flower nectars or pollen which serve as food for them. Once flowers are available during the spring, the butterflies come around and when the winter comes and the flowers disappear, they migrate away.
Answer:
A
Explanation:
migration, which is a response to an external stimulus
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 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.
