What helps exploding pods disperse

Answers

Answer 1

Answer: Pods of certain plants such as gorse and pansies have a way of flinging their seeds when ripe in every direction with considerable force. The thing that helps these seeds disperse is first and foremost the mechanical force itself used to catapult the seeds.

As they ripen, the seed pods gradually lose moisture, building up tension in their cells and subsequently in the pod as a whole. The structure inevitably fails gradually and during a hot day it gives way altogether due to heat stress and triggers an explosion firing the seeds with appreciable force away from the parent plant almost like a projectile for up to 100m (300 ft) away.

It is important to note that plants which use this explosive method or ballistic dispersal as it is also called tend to have seeds that are generally large and too heavy to be carried by the wind unlike those of plants such as dandelions which are light enough for wind dispersal. Therefore gorse and suchlike plants employ ballistic methods to ensure their seeds travel as far away from the parent plant as possible.

Viruses do not possess all the characteristics of life. Identify those characterustics that viruses display and those they don't display?

Answers

The main aspect of viruses that causes controversy over it being classified as living is its manner of reproduction.

Viruses do reproduce, like a living organism. However, they cannot do so without a host cell, so they are unable to reproduce on their own, which means that they are not living.

Answer: A: Decreases

Explanation: The pressure is the ratio of the weight of the air to unit area. So, as the height increases, the pressure decreases.

What is transcription in biology

Answers

Transcription is the first step of gene expression, in which a particular segment of DNA is copied into RNA by the enzyme RNA polymerase. Both DNA and RNA are nucleic acids, which use base pairs of nucleotides as a complementary language.

Compare all the organisms. What trend do you see? The proportions of DNA bases vary greatly among organisms. The proportions of DNA bases are similar in closely related organisms, but different in organisms that are not closely related. The proportions of DNA bases are similar among all organisms.

Answers

Answer:

Option 3. The proportions of DNA bases are similar among all organisms.

Explanation:

The DNA is composed of two nitrogen bases called the nucleotide and four nucleobases joined by hydrogen bonds namely:

Adenine (A) 2. Guanine(G) 3. Cytosine (C) 4. Thymine (T)

The proportion and the number of the bases and base pairing are the same in all organisms but what makes an organism different is the order in which they're arranged.
The DNA coding depends on the order of gene expression determined by a specific arrangement of DNA molecules in each organism.
Out of the 3 billion bases found in humans 99% of the bases are similar in all.
