Biology

qaws [65]2 years ago
8 0

Explanation:

The three standard sex symbols are the male symbol ♂ and the female symbol ♀, and the hybrid symbol ×. They were first used to denote the effective sex of plants (i.e. sex of individual in a given crossbreed, since most plants are hermaphroditic) by Carl Linnaeus in 1751.

Membrane lipids in tissue samples obtained from different parts of the leg of a reindeer have different fatty acid compositions.
AnnZ [28]

Answer:

The presence of a larger proportion of unsaturated fatty acids in membranes imparts them fluidity at lower temperatures as required to maintain their normal functioning.

Explanation:

The proportion of unsaturated and saturated fatty acids in membranes regulates their fluidity. At lower temperatures, membranes become more rigid. To maintain their normal fluidity, the proportion of the unsaturated fatty acids in membranes is increased. The unsaturated fatty acids have double bonds in their hydrocarbon tails which in turn do not allow their tight packing and impart fluidity to the membrane core.

At higher temperatures, membranes become more fluid and therefore, the proportion of the unsaturated fatty acids is reduced. The tissues of reindeer at the body's extremities such as those near hooves are exposed to surroundings and thereby, lose heat and have lower temperatures. To maintain the fluidity of membranes, the cells of these tissues incorporate more of the unsaturated fatty acids in their membranes as compared to the tissues in the upper legs where the body temperature is relatively higher.

Where is the carbon taken in by plants during photosynthesis stored?
KIM [24]

The carbon taken in by plants during photosynthesis stored in "plant structures".

<u>Option: </u>B

<u>Explanation:</u>

The carbon drawn in by photosynthesis plants is contained in the structures of the plants in the form of polysaccharides such as starch, cellulose, etc. When plant absorbs carbon in the context of glucose using photosynthesis, plants use a certain amount of glucose to generate energy for their day-to-day activities, while the plant retains the excess amount of glucose for potential use in special organelles understood as amyloplasts and stored in roots, stems, tubers, etc like various structures of the plant.

Eric follows a vegetarian eating pattern, and he wants to know whether he needs to take any vitamin and mineral supplements. wha
Reil [10]

It would be most important for Eric to find out his <em>zinc, iron and vitamin B12 (or  riboflavin) levels, and ensure that he is obtaining adequate amounts of these vitamins and minerals through vegetarian sources </em>.

A vegetarian diet is typically low in zinc rich foods, since meat, shell fish and eggs are the most abundant sources of zinc. In order to ensure that he obtains sufficient zinc, Eric should make sure he consumes vegetarian zinc sources such as legumes, lentils, dairy, nuts and seeds on a daily basis.

Since iron and vitamin B12 are also difficult to obtain from vegetarian sources, Eric should consume iron rich foods such as spinach, kale, whole grains, broccoli, legumes,etc., on a daily basis. As for vitamin B12, daily supplementation of 2.4 μg is recommended for vegetarians. Alternatively, riboflavin fortified cereals and grains are also recommended to meet daily riboflavin requirements.
