Which is the most likely result if the Ubx gene was activated either before or after it normally is activated in the sequence of Hox gene expression?


A. The insect develops slightly shorter or longer abdominal legs.

B. The insect develops normal body parts at either a slower or more rapid rate.

C. The insect develops normal body parts but in an altered time sequence.

D. The insect develops legs in other parts of its body.

Answers

Answer 1

Answer:

D. The insect develops legs in other parts of its body.

Explanation:

HOX genes, also known as homeotic genes, are evolutionarily conserved genes (containing homeobox sequences) that encode master regulators of embryonic development in animals. Hox genes modulate the body plan of an embryo along the head-tail axis. In general, these genes are arranged in the same order as they are transcriptionally expressed along the anteroposterior body axis. Moreover, Ultrabithorax (Ubx) is a Hox gene that is responsible for the proper development of the third thoracic segment in insects. In Drosophila, it has been shown that different segments of the leg regulate their size in response to Ubx expression.

Which of the following is an accurate description of a positive feedback loop? SC.912.E.7.7

A.
It is uncommon in nature and it makes systems stable.

B.
It is common in nature and it doesn’t change the stability of systems

C.
It is uncommon in nature and is usually caused by humans

D.
It is common in nature and it makes systems stable

Answers

Regulatory functions such as feedback loops are very common in nature and happen thousands of times every day within our bodies alone.

A feedback loop is one of the methods by which biological organisms regulate functions. Feedback loops are a self-regulatory means through which the output of a system is then used as the input. Feedback loops can be of two types:

Positive FeedbackNegative Feedback

A positive feedback loop is one in which the system is stimulated to increase the production of a product. For example, the low levels of an enzyme in the blood will cause the body to produce more of that enzyme in a positive feedback loop. A negative feedback loop is just the opposite, in which high levels will cause a decrease in production.

Feedback loops are a vital part of maintaining homeostasis and for the survival of all organisms. Therefore, we can conclude that option D is correct in stating that feedback loops are common in nature and make the system stable.

When do plants make the most sugar?

Answers

Answer: All green plants make sugar through photosynthesis, the process plants use to transform the sun’s energy into food.

Explanation:

Answer:

Both photosynthesis and respiration occur within plant cells. During the day, photosynthesis is the dominant process in plants. This means that the plant produces more glucose than it uses during respiration. At night, or in the absence of light, photosynthesis in plants stops, and respiration is the dominant process.

the wing of a penguin is ________ the arm of a human.

Answers

The wing of a penguin is homologous to the arm of a human.

Homologous organs refer to organs of different organisms that are structurally similar but functionally different.

The wing of a penguin and the arm of a human are structurally similar because they are both built on the same pentadactyl or five-digit plan.

Despite the structural similarity, the wing of a penguin and the arm of a human are adapted for different functions. While the wings of a penguin are used to propel the animal in water by flapping them together, the arms of a human are adapted for several functions, including swimming when necessary.
