Answer:
The lactose present prevents the production of lactase
Explanation:
This question is describing a set of genes in bacteria called LAC OPERON. Lac operon controls the production of lactase, which is the enzyme that digests lactose. However, this gene can be regulated at the transcription level i.e caused to be transcribed or not depending on certain factors.
According to the question, lac operon, which regulates the production of enzymes will be transcribed and subsequently translated i.e. turned on when there is a substrate (lactose) that the produced enzyme will work on. However, when there is no need of the lactase enzyme or there is absence of lactose (substrate), the lac operon gene is turned off.
Note that, the statement that "The presence of lactose prevents the production of lactase" is not correct.
Answer:
Although humans and animals (technically “non-human animals”) may look different, at a physiological and anatomical level they are remarkably similar. Animals, from mice to monkeys, have the same organs (heart, lungs, brain etc.) and organ systems (respiratory, cardiovascular, nervous systems etc.)
Humans have a heart with two atria and two ventricles that pushes blood in one direction. Some animals have hearts similar to humans but, other animals have only one atrium and one ventricle or a cardiovascular system that can push blood in two directions.
Memory for stimulus sequences distinguishes humans from other animals. Summary: Humans possess many cognitive abilities not seen in other animals, such as a full-blown language capacity as well as reasoning and planning abilities.

global warming is a increase in earths overall temperture caused increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants.
to prevent global warming we could:
Drive less, Recycle more, Use less hot water, Plant a tree, Turn off electronic devices when not being used such as a T.V
all of these ideas save pounds of carbon dixoide and if you look above it is listed as a cause of global warming
Answer:
‼️‼️‼️155.4 calories‼️‼️‼️
Explanation:
1 gram of fat = 9 calories
1 gram of carbohydrates = 4 calories
1 gram of protein = 4 calories
11x9 = 99
1.1x4 = 4.4
13x4 = 52
This would get you go this question thus the answer to your question
99 + 4.4 + 52 = 155.4 calories
