How does passive transport occur?​

Biology
1 answer:
Setler [38]3 years ago
6 0

Answer:

In passive transport, substances move from an area of higher concentration to an area of lower concentration. Diffusion through a permeable membrane moves a substance from an area of high concentration (extracellular fluid, in this case) down its concentration gradient (into the cytoplasm).

Angiosperms, dicots

Explanation:

Angiosperms are highly differentiated vascular plants which can produce flowers and bear fruits with seeds in them. These flowering plants undergo reproduction and produces new plants. The reproductive parts like ovules and ovaries, stigma, stamen, pollen are all present in the flowers.

Angiosperms can either be a monocot or dicot. If they contain two embryonic leaves or cotyledons they are referred as dicots. Flowering angiosperms like geranium, magnolias are all dicots.

Geranium is a dicot angiosperms that produces small purple flowers.

Gymnosperms or bryophytes do not bear flowers or fruits. Monocots have only embryonic leaf.

The diagram shows structures found in a seed plant. What is the function of labeled X
Alja [10]

Question is incomplete. Complete question has been attached.

Answer:

carries food produced by leaves

Explanation:

The diagram is a cross section of stem of a dicot plant, specifically <em>Hypericum perforatum</em>. It shows all the structures present in the stem like xylem, phloem, pith, cortex etc. The structure labelled X is phloem. It is present between xylem (stained red) and peripheral cortex. Phloem is responsible for conduction of sugars and nutrients in the plant thus it carries the food produced by leaves. Together xylem and phloem make the vascular tissue which surrounds the central pith (stained bluish-green).

The Coriolis effect happen when ?
Pie
The Coriolis effect<span> is caused by a combination of the inertia of moving air and the rotation of the Earth. Air tends to move from high pressure to low pressure in a straight line, but the rotation of the Earth means that, to an observer at one spot on its surface, the moving air appears to turn.

The largest and most complex mitochondrial genomes come from _____.
alexandr1967 [171]

Answer:

Angiosperm

Explanation:

The mitochondria of flowering Angiosperm plant are the largest. The size of these mitochondria varies from 1.86 million bp to 2.4 million bp. It is also the most complex one as it carries large number of repeating units which allows multiple permutations for recombination. This allows generation of mitochondria of varying sizes with in the same species.

It is least gene dense  as the inter regions are highly expanded. One of the most distinguishing feature of these mitochondria's are that they contain polypeptides. These polypeptides are basically non functional but have potential to evolve into functional one.

Gause's experiments on two species of paramecium with very similar niches allowed him to formulate the principle of competitive
iren [92.7K]

The given example suggests the principle of resource partitioning.

The resource partitioning is a method of division of resources present in a particular niche to avoid the competition. In this case, the organism divide the regions having the abundant resources and they do not interfere in each others region.

In this case, the resource partition takes place by dividing the regions in the flask. one species use he resources present in the middle region and other uses the resource in the bottom.
