all of the above

Answers

Answer 1
Answer: Factors that margins production are considered limiting factors. Temperature, nutrients, pH, salinity. and light are the most considered limiting factors in an ecosystem. Among the aforementioned factors, there are only three that are considered as universal limiting factors. These are: temperature; pH; and, salinity. These 3 factors affect the growth of organisms in the ecosystem, as well as their growth development. According to some research, temperature affects the physiochemical limit of an organism. Salinity on the other hand affects the organisms' mobility, (organisms vary salt tolerance) or suspends cell division. The pH of water also affects the organisms' physiological performance, specifically the aquatic organisms. The answer to this question then is letter D," all of the above".

How do hydrophobic signalling molecules travel around the body?

Answers

Answer:

Hydrophobic molecules don't like water,just like the membrane.Since the membrane and these signaling molecules are made of the same thing,liquid,they can easily mix together.

Explanation:

Hydrophobic signalling molecules move right through the cell membrane to the target inside the cell.

The air spaces in the _________________ layer of a leaf connect with air through stomata in the epidermis of the leaf.

Answers

Answer: The air spaces in the spongy layer of a leaf connect with air through stomata in the epidermis of the leaf.

Explanation:

The cells in the spongy layer of the leaf contain less chloroplast but act as storage for product of photosynthesis like sugars,amino acids and bases.

The air spaces in the spongy layer connect with air through stomata in the epidermis of the leaf. The air spaces in spongy layer allow diffusion of carbondioxide and oxygen and stomata which is a small pores in the epidermis allow carbondioxide and oxygen to enter and leave the leaf.
The air spaces in the spongy layer.

B. to inform readers about new ideas about the disease using scientific evidence as support

C. to narrate the consequences of contracting the disease

D. to describe the lack of sanitation at the time of the story

Answers

"On the mode of communication of cholera" was written by Dr. John Snow in order to spread awareness about the disease and the new ideas giving scientific proof along with them. Through his text, he aimed at persuading the citizens and the officials to become more aware regarding the sanitation of their surroundings as Cholera is transmitted via the dirty surroundings. In his text he discussed the causes of spread, instances and scientific evidence of Cholera of its communication among different populations.

Hence, the correct answer is 'Option A and B'.
