1. Why does sand settle to the bottom of a jar<br> faster than mud does?<br> 2. What is sediment?
Marysya12 [62]

1. Sand particles are too big to dissolve so their density sinks them

2. Sediment is a naturally occurring material that is broken down by processes of weathering and erosion, and is subsequently transported by the action of wind, water, or ice or by the force of gravity acting on the particles.

Protists are very diverse, and many different classification schemes have been used to define relationships between the protists
andrey2020 [161]

Answer:

D. heterotrophic by ingestion, pseudopods

Explanation:

Protists are generally classified  as all eukaryotic organisms that are not plants, animals or fungi. Example is amoeba, paramecium etc.They may be unicellular or multi cellular in nature.Most exist in colonies.

Their mode of nutrition can be photosynthetic or hetrotrophic. Hetrotrophic  protists   can be divided into  phagotrophs and osmotrops/saprotrophs. The phagotrophs  makes use of the cell body to engulf the food materials as  in amoeba ,carry out extracellular digestion before swallowing it.

Osmotrops absorbed dissolved food from surrounding liquid environments directly. (Some photosynthetic protists can also be heterotrophic.

Amoeboid movement is the mode of locomotion of protists and some  other eukaryotes. It involved the protrusion of cytoplasm, which exert pressure on the cell membrane to form pseudopodia and  the posterioly  evolved  <u>Uropods. </u>

<u />

<u>  </u>

<u>Sol-gel theory has been proposed to expalin this movements, The ectopalsm of amoeba is gelly-like , while the endiplams is less viscpus   and said to be sol. The interchange of the cytoplasmic fluis between the endo-and ecto plasm gives the SOL-GEL propulsion of the protopalms for the amoebic moveemnts .</u>

<u />

<u>The false feet(psuedopodium) drags the amoeba  along in the direction of the flow of the cytoplasm.</u>

Therefore option D is  the right option

Hemoglobin is the protein that transports oxygen in mammals. Different species of mammals have slightly different forms of hemog
slavikrds [6]

Answer:

The correct answer is - 6.8950.61 gm per mole

Explanation:

Given:

One form of hemoglobin is 0.324% Fe by mass

1 hemoglobin = 4 Fe

Solution:

Molar Mass of iron = 55.85

mass of 4 iron atom = 55.85 * 4 = 223.4 gms

0.324 % correspond to 223.4 gms

100 % correspond to = 223.4 *100/0.324

= 68950.61 gm

MM of haemoglobin = 68950.61 gms = 6.8 E4 gms
