padilas [110]

Answer and Explanation:

Land - Lion

Water - Sealion

Flies - Bees

Lions have strong retractable jaws that help them eat their prey and that way they adapt to their enviroment.

The Sealion's thick, oily fur and a layer of blubber allow them to keep a high temperature in cold waters.  

A Bees body carries an electrostatic charge that attracts pollen and that way they can keep it in them.

Hope this Helps! Have a GREAT day!

Explain how carbon atoms become part of a plant
Keith_Richards [23]
Some of the carbon atoms in the glucose exit the leaf as carbon dioxide during respiration while other carbon atoms are used to make important parts of the plant, such as additional leaves or wood. Carbon atoms that remain in leaves will either fall off (during plant senescence) or become a meal for an animal. Hope this helps

Saccharomyces cerevisiae is a diploid yeast species that can reproduce either sexually or asexually. An experiment was performed
Savatey [412]

Answer:

D. The first division will reduce the number of chromosomes by half for each daughter cell, and the second division will move single chromatids to each daughter cell.

Explanation:

Gametes are formed by meiosis in diploid gamete mother cells. During gamete formation, the gamete mother cell in the yeast would undergo meiosis I. During first division (meiosis-I), the process of crossing over during prophase-I creates genetic variations and movement of homologous chromosomes to the opposite poles during anaphase-I reduces the chromosome number to half in each daughter cell.

Two daughter cells are formed by the end of meiosis-I each of which enters meiosis-II. Splitting of centromere and separation of sister chromatids during anaphase-II of meiosis-II results in the movement of single chromatids to the opposite poles of the cells.

Most fish need a minimum of ________ parts per million of dissolved oxygen in seawater to survive for long periods.
Andrei [34K]

Most fish need a minimum of 4 parts per million of dissolved oxygen in seawater to survive for long periods.

<h3>How can you mesure dissolved oxygen in water?</h3>

Dissolved oxygen (DO) is estimated utilizing a disintegrated oxygen meter or DO meter. The best strategy is to take the estimation in the field simultaneously every day, in light of the fact that DO fixations can shift all through a 24 hour time span.

Testing disintegrated oxygen (DO) in water is either estimated by means of substance examination, for example, a titrimetric technique, electroanalytical utilizing galvanic and polarographic tests, optical broke up oxygen, and colorimetric strategies.

In any case, present day procedures basically utilize electrochemical or optical sensor techniques.

The Winkler Method is a procedure used to quantify broke up oxygen in freshwater frameworks. Disintegrated oxygen is utilized as a mark of the wellbeing of a water body, where higher broke up oxygen fixations are corresponded with high efficiency and little contamination.

Disintegration of natural material,Bacterial oxidation of dead natural material consumes oxygen. This likewise makes sense of the relating expansion in supplement levels underneath the epipelagic zone.
