How did gravity affect the growth of the germinating corn seeds?

Answers

Answer:

see below

Explanation:

their roots respond positively, growing down, into the soil, and their stems respond negatively, growing upward, to reach the sunlight.

Gravity influenced the growth of germinating corn seeds by providing the directional cue for root growth and promoting proper orientation of the plant.

Gravity plays a crucial role in plant growth and development, particularly during the germination of seeds. When a germinating corn seed is placed in a gravitational field, gravity acts as a guidance mechanism for the growing seedling.

In response to gravity, the root of the germinating seed grows in a downward direction, a process known as gravitropism or geotropism. This downward growth of the root is called positive gravitropism. The root responds to the gravity stimulus by redistributing auxin, a plant hormone, towards the lower side of the root. This causes cells on the lower side of the root to elongate more than cells on the upper side, leading to downward growth. The downward growth of the root helps anchor the plant in the soil and facilitates water and nutrient absorption from the ground.

Simultaneously, gravity also influences the shoot of the germinating corn seed. The shoot exhibits negative gravitropism, where it grows upward against the force of gravity. This upward growth is counterbalanced by the downward growth of the root, allowing the plant to establish proper orientation.

Without the presence of gravity, the germinating corn seeds would not be able to establish the proper orientation and direction of growth. The root may not grow downward, leading to irregular and inefficient water and nutrient absorption. The shoot may not grow upward, resulting in an abnormal and compromised overall plant structure.

Therefore, gravity serves as a crucial external factor that guides the growth of germinating corn seeds, ensuring proper root development, anchorage, and shoot orientation for successful plant growth.

Explanation:

Horizontal cells are the laterally interconnecting neurons having cell bodies in the inner nuclear layer of the retina of vertebrate eyes. They help integrate and regulate the input from multiple photoreceptor cells. Without them you wouldn't be able to see color, which means the mouse won't process color.

Due to a genetic modification, a mouse has no horizontal cells in its retinas and it does not expresses the connexin26.

Why would it be incorrect to say that the DNA sequence A-C-G codes for the amino acid threonine?

Answers

It would be incorrect to say that the DNA sequence A-C-G codes for the amino acid threonine because mRNA codons code for amino acids not DNA.

What is a codon?

A codon is a triplet nucleotide sequence that encodes a particular amino acid.

A DNA sequence is transcribed into mRNA sequence, which is read in a group of three nucleotides called codon.

Each mRNA codon (three letter) encodes an amino acid.
