Mammals like caribou that live in the arctic often use different lipid types in their legs. Legs are more susceptible to heat lo

ss than internal organs, which are closer to the body core and stay warmer. Which adaptations would you expect for lipids in caribou legs?
1. The lipids would be more saturated. True / False
2. The lipids on the fatty acid tails would be shorter. True / False
3. The membranes would contain more cholesterol. True / False

1. The lipid would be more saturated. FALSE

2. The lipids on the fatty acid tails would be much shorter. TRUE

3. The membranes would contain more cholesterol. TRUE

<u>Explanation:</u>

The mammal caribou lives I the extremely cold environment of the Arctic and thus has several physiological adaptations to survive the cold. They have short ears to reduce heat loss and have two layers of fur. The lipids in caribou legs have several adaptations

When compared with saturated fatty acids unsaturated fatty acids are more fluid at low temperatures. Thus the lipids in the legs of caribou are unsaturated to maintain fluid nature at low temperatures of the Arctic. Shorter lipids on fatty acid tails remain more fluid at low temperatures when compared with the longer ones.  

Thus the lipid in the fatty acid tails will be shorter. Similarly the presence of more cholesterol in the membranes would make it more fluid in the cold conditions of the external environment. Thus the membranes would have more cholesterol.

Which element would you expect to be more unstable/reactive, neon or calcium? why?
melamori03 [73]

Answer:

Calcium

Explanation:

Between Neon and Calcium, neon will be more stable compared to the calcium.

Neon belongs to the group of elements on the periodic table called the noble gases. These are the most stable elements and they do not react with other elements.

  • Calcium on the other hand is reactive
  • It requires a loss of two electrons to attain stability.
  • Therefore, it is a more reactive element.

How are vascular and non-vascular plants different, and how do each of them work through osmosis?
Lilit [14]

Answer:

Explanation:

Vascular plants have tubelike structures that carry water, nutrients, and other substances throughout the plant. Nonvascular plants do not have these tubelike structures and use other ways to move water and substances.

Vascular plants are said to have a true stem, leaves, and roots due to the presence of vascular tissues. Non-vascular plants do not have true roots, stems, or leaves and the tissues present are the least specialized forms of tissue. Some examples of vascular plants include maize, mustard, rose, cycad, ferns, clubmosses, grasses. Some examples of non-vascular plants include moss, algae, liverwort, and hornwort.

How vascular plants work through osmosis

The xylem of vascular plants consists of dead cells placed end to end that form tunnels through which water and minerals move upward from the roots to the rest of the plant. Through the xylem vessels, water enters and leaves cells through osmosis.

How non vascular plants work through osmosis

Because non vascular plants do not have the xylem and phloem ystem, they absorb water right into their cells through their leaves when it rains or when dew falls. Internal cells get their water by passive osmosis. While, they use rhizoids to transport nutrients and minerals.

Procedure
lana66690 [7]

The correct order of steps in an experiment would be:

  • Identify the variables.
  • Write out your hypothesis in an if/then format.
  • Gather your materials.  
  • Analyze the data.
  • Write your conclusion.

<h3>What is an experiment? </h3>

An experiment is a term to refer to the process by which a hypothesis is supported/disproved. The experiments serve to explain the cause-and-effect relationship according to the results obtained.

Experimentation has some important steps that we must follow to demonstrate our ideas regarding a scientific manifestation, these steps are:

  • Identify the variables: We must identify the factors that we can manipulate so that the result changes.
  • Write our hypothesis: Establish a hypothetical result that we are going to demonstrate.
  • Gather the materials: We must have all the materials and variables to be able to carry out our experiments.
  • Analyze the data: When we do an experiment we must record everything we see and then analyze it to examine each step and the procedures performed.
  • Write the conclusion: After analyzing the data obtained, we can write a conclusion about the experiment carried out and the result obtained.
