According to this dichotomous key, any catfish must have

A red blood cell will shrink in size when placed in a more concentrated salt solution because of the passive process called

Leto [7]

This process is called osmosis whereby water exits the cell through its selectively permeable membrane and into the salt solution to dilute and balance the pressure caused by the concentrated salt solution.

On your first research mission you make an amazing discovery by finding a new species living in the hostile environment of the s

Tomtit [17]

The best classification for this new species is Animalia.

According to the six kingdom classification given by Carl Woese, all organisms are divided into 6 kingdoms.

1) Archaebacteria

2) Eubacteria

3) Protista

4) Fungi

5) Plantae

6) Animalia

As the newly discovered species is a multicellular (made up of more than one cell) organism.

Then it can only belong to Kingdom Fungi, Plantae and Animalia as the rest of the kingdoms like Archaebacteria, Eubacteria and Protista consist of unicellular organisms that are made up of only one type of cell.

Now this species is not autotrophic ( i.e. an organism that can get its own nutrition by the use of light, water, carbon dioxide, or other substances).

It means it is heterotrophic which means it can't get nutrition on its own.

Out of the Fungi, Plantae and Animalia , only fungi and Animalia kingdoms consist of heterotrophic organisms.

Now this species also does not contain chitin which is an important characteristics of Fungi.

So only option left is Animalia.

Hence, the best classification for this new species is Animalia.

How does solid rock become soil

kipiarov [429]

rocks can become soil in multiple different ways one could be primary succession which means some algae or moss grows onto rocks with out soil then they slowly gain moisture which attracts some other plants like flowers which then breaks down the rock into smaller things then grasses come in and turns it into soil.

Wheat has flowers similar to those in Fig. 5.1, but reproduces by self-pollination. Explain the consequences of self-pollination

Salsk061 [2.6K]

Answer:

The transfer of mature pollen grain from anther of the flower to the stigma of the same flower of the same [species is called self pollination.

Generally, the transfer of pollen grains by wind,animals,and water to stigmas is called pollination. It is a means of vegetative propagation which ensures reproduction.

Therefore during self pollination, the same genes are distributed from one generation to another. Thus genetic purity is ensured. It also ensured reproductive success. because there is little chance of the pollen grain getting lost in transit. It is also certain a particular plant would always breed true.

Additionally it prevent the process of transfer of genes in some transgenic crops( rice, maize) where through genetic engineering some genes are introduced in their genome.

The only negative effect is lack of genetic diversity. Therefore after a period of time the plants get weak and prone to diseases and infection. Because of poor resistant from lack of variation.
