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.

Answer:

The organism selected based on sexual reproduction is tortoise and based on asexual reproduction is hydra. Both of them are explained in detail below with diagrams.

Explanation:

Tortoise: These are land dwelling reptiles and have a hard shell on their back to protect from predators. They can pull their necks inside for protection. They are different from turtles which as aquatic in nature. They mostly sleep at night and are active during day. These organisms prefer to stay isolated and are not comfortable in crowds.Tortoises have very long life span that between 80-150 years with the oldest one being 255 years.

Sexual reproduction- In most cases, females tend to be larger in size than males. They reproduce sexually by laying eggs at night. Their gametes are haploid in nature which when fused result in a diploid organism. The number of chromosome in a tortoise is 52.

The tortoise eggs can remain fertile till four years after fertilization. One single mating allows 30 eggs to be fertilized. Once the female finds the right environmental conditions, the eggs are laid.

Advantage of sexual mode of reproduction:

Offspring produced have genetic variation.
This genetic variation allows them to adapt well to the surrounding.
All the offspring don not die of a single disease because they are genetically varied.

Disadvantages: Fewer organisms are produced.

Gap between mating season.

Hydra is a fresh water organism belonging to class Cnidaria. It's body has a radial symmetry. The body contains stinging cells known as cnidocytes, which contain neurotoxins. These are released when faced by a predator. Its body is made up of two layers-epidermis and gastrodermis.

If a hydra is cut in half, both the cut parts regenerate into two new hydra. Their mode of reproduction is asexual through the process of budding. a

A new bud arises in some part of the body of hydra which matures and breaks off to form a new hydra. Most hydra are fixed or senile but some of them are free moving.

Advantages of asexual reproduction:

The population multiplies rapidly in favorable conditions.
Single parent is needed.
It's faster than sexual reproduction.

Disadvantages of asexual reproduction:

Limited diversity
Population becomes difficult to control.
Negative mutation continue through the cell lines as there is no mixing of gametes.

Data samples in which you expect no change to occur are_____.

mina [271]

The answer is negative controls. These are groups where no phenomenon is probable. They ensure that there is no effect when there should be no effect. Where there are only two possible outcomes, e.g. positive or negative, if the treatment group and the negative control both produce a negative result, it can be concluded that the treatment had no effect. If the negative control group and the treatment group both yield a positive result, it can be inferred that a puzzling variable is involved in the occurrence under study, and the positive results are not only due to the treatment. In other examples, outcomes might be measured as lengths, times, percentages, and so forth.

Answer:

Sexual reproduction involves two parents and the joining of male and female gametes during fertilisation. The offspring inherit a mixture of genes from both parents, so are different to each other and their parents. In asexual reproduction there is only one parent. The offspring are clones of the parent and each other.
