One line with red flowers and the other line with violet flowers. You carry out a monohybrid cross and find that all of the F1 offspring have violet flowers, while 97 of 400 F2 offspring have red flowers.
Explain the inheritance of flower colour in this plant species.
Answers
Answer:
See the answer below
Explanation:
The inheritance of flower color in the plant species follows the simple dominance/recessive inheritance of Mendel. The red flower trait did not show up at all at F1 only for it to show up at F2. It simply means that the red flower trait is recessive while the violet flower color is dominant.
Assuming that the allele for violet flower color is designated as R while that of red flower color is designated as r. The genotype of the violet flower would be true-breeding, RR, while that of red flower color would also be true-breeding rr:
RR x rr
F1 Rr Rr Rr Rr
phenotype ratio = all violet flower color
Rr x Rr
F2 RR Rr Rr rr
phenotype ratio = 3/4 violet flower color and 1/4 red flower color
97 red flower offspring out of 400 is approximately 1/4.
Hence, the inheritance of flower color in the plant obeys a simple dominant/recessive Mendelian law with the violet color trait dominant over the red color trait.
How do plant cells differ from animal cells
Answers
Answer: Plant cells have chlorophyll, chloroplasts, cell walls, a more blocky shape, and larger vacuoles. Animal cells have a more rounder shape, no cell wall but only a cell membrane, smaller vacuoles, and other organelles such has centrosomes, which plant cells don’t have.

The Chatham Island robin is a small endangered bird found in scrub forests off the coast of New Zealand. The robin is preyed upon by introduced species such as cats and rats. In 1980, the population decreased to only 5 individuals and every individual today is a descendant of a single female. Which of the following is best illustrated in the decline of the Chatham Island robins?
1. Carrying capacity
2. Population bottleneck
3, Population overshoot
4. Type I survivorship
Answers
Answer: 2. Population bottleneck
Explanation:
A Population bottleneck is a term used to refer to an event that causes the population of a species to reduce in very large numbers. Such an event can be environmental disasters like famine, the overhunting of a species or the destruction of its habitat.
In the case of the Cha-tham Island Robin, the bottleneck event must have been the introduction of cats and rats which then went on to hunt the birds to near extinction.
The maximum number of individuals that an environment can support is called the ___. A)population density B)Competition Factor C)density Independent factors D)carrying capacity

What is the second most abundant element on earth and seems to be very important in biological processes such as oxygen transportation in the body and cellular respiration
Answers
Answer:
iron
Explanation:
Cellular respiration may be defined as the group of metabolic processes as well as reactions which occurs in the cells of the organisms that converts the chemical energy from the oxygen molecules or from nutrients into ATP or adenosine triphosphate and then releases the waste products. Thus it breaks the glucose and produces the ATP. Iron is an important element which are used in many important biological processes in the body like the cellular respiration and oxygen transportation.

Why is it difficult to know the impacts of deep sea mining?
O It has never been tried successfully, so we don't know exactly how it can be done.
Olt is only done in environmentally sensitive areas, where the organisms are being harmed in many ways already, and it is difficult to know the effects of mining.
We know relatively little about deep sea ecosystems, making it harder to assess the impact of mining.

Explanation:
We know relatively little about deep sea ecosystems, making it harder to assess the impact of mining.
Deep sea mining has never been tried successfully, so we don't know exactly how it can be done so it is difficult to know the impact of deep sea mining.
what is deep sea mining?The process of extracting and often excavating mineral deposits from the deep seafloor is known as deep-sea mining.
The deep bottom spans around two-thirds of the total seafloor and is found at ocean depths greater than 200 meters.
Deep-sea mining has been shown to affect marine biodiversity and ecosystems, but we still lack the knowledge and resources to safeguard them.
There are considerable gaps in our understanding of the deep sea's biodiversity and ecosystems since it is still understudied and poorly understood.
This makes assessing the possible effects of deep-sea mining and putting in place necessary safeguards to protect the marine ecosystem and the three billion people whose livelihoods rely on marine and coastal biodiversity challenging.
Hence , the correct option is A.
